Autores: Gomez Selvaraj,Michael; Narayana,Manivannan; Schubert,A. Michael; Ayers,Jamie L; Baring,Michael R; Burow,Mark D.
Bulked segregant analysis was used to identify simple sequence repeat (SSR) markers associated with pod and kernel traits in cultivated peanut, to permit rapid selection of superior quality genotypes in the breeding program. SSR markers linked to pod and kernel traits were identified in two DNA pools (high and low), which were established using selected F2:6 recombinant individuals resulting from a cultivated cross between a runner (Tamrun OL01) and a Spanish (BSS 56) peanut. To identify quantitative trait loci (QTLs) for pod and kernel-related traits, parents were screened initially with 112 SSR primer pairs. The survey revealed 8.9% polymorphism between parents. Of ten SSR primer pairs distinguishing the parents, five (PM375, PM36, PM45, pPGPseq8D9, and...

INFLUENCE OF OPERATIONAL CONDITIONS OF MECHANIZED HARVESTING ON SUGARCANE LOSSES AND IMPURITIES
Provedor de dados: 70
Autores: Martins,Murilo B.; Ruiz,Daniel.
ABSTRACT Operational conditions of mechanized harvesting can affect the quality of harvested sugarcane. Therefore, the aim of this study was to assess the influence of the displacement speed and cutting height on the quality of the raw material during the mechanized harvest of sugarcane. Vegetable losses were accounted for in the field by manual collection of the fractions left after harvest. Vegetable and mineral impurities were determined at the processing stage in the laboratory. Both the displacement speed and cutting height did not affect vegetable losses. However, the increase in vegetal impurities occurred at higher displacement speeds, whereas lower cutting heights resulted in higher amounts of mineral impurities.

ABSTRACT This study aimed to assess the drying kinetics of red and yellow chili peppers, “dedo-de-moça” variety, at different temperatures (35, 45, 55, and 70 °C) and model this phenomenon mathematically. We also evaluated the effect of these drying air temperatures on pepper fruit color. Pepper fruits were dried in a forced-air circulation dryer. Ten mathematical models were fitted to the experimental data by nonlinear regression analysis. After drying, pepper samples were analyzed for the following colorimetric parameters: lightness (L*), chroma or saturation (c), and hue angle (h), in order to determine the influence of drying air temperature on fruit coloration. Our findings showed that the higher the air temperature, the faster the drying process....

ABSTRACT Numerous factors are related to the individual sensory perception of consumers, which makes it impossible to adapt a model that explains their behavior. In this context and given the scarcity of statistical indexes that evaluate preferences for specialty coffees, new statistical methods should be studied. To this end, our study aimed to create an index that measures the acceptance of specialty coffees. The index was built considering the fit of regression models as a function of principal component scores. Validation was done by significance tests, whose probabilities were obtained by bootstrapping, considering the main measures used in diagnosing outliers as weights, with application to real data from different consumer groups. The coffee...

ABSTRACT Statistical process control in mechanized farming is a new way to assess operation quality. In this sense, we aimed to compare three statistical process control tools applied to losses in sugarcane mechanical harvesting to determine the best control chart template for this quality indicator. Losses were daily monitored in farms located within Triângulo Mineiro region, in Minas Gerais state, Brazil. They were carried over a period of 70 days in the 2014 harvest. At the end of the evaluation period, 194 samples were collected in total for each type of loss. The control charts used were individual values chart, moving average and exponentially weighted moving average. The quality indicators assessed during sugarcane harvest were the following loss...

Provedor de dados: 75
Autores: Camelo,Andrés F.Lopes; Horvitz,Sandra; Gómez,Perla A.
The onion is a major export crop in Argentina and obtaining consistent quality is a matter of concern to remain competitive internationally. Grading is generally done according to Mercosur standards but quality assurance programs are necessary at the packinghouse level. The objective of this study was to develop a first approach for characterizing sorting and sizing efficiency. During the 1998 season five onion packinghouses located in the Valle Bonaerense del Río Colorado (Buenos Aires Province, Argentina) were randomly selected. In all of them, variables measured were: sorting table width, bulb transport and rotation speed as well as number of bulbs/sorter/hour. Before and after sorting, samples of 100 bulbs of each size category were randomly taken and...

Autores: Cardoso,Jean C; Ono,Elizabeth O; Rodrigues,João D.
The flower industry represents about one billion dollars in Brazil and the development of techniques aimed at flowering control is required. This study evaluated the influence of gibberellic acid (GA3) on the vegetative and reproductive development of young plants of Phalaenopsis FSNT 'Dai-Itigo' hybrid pink color. The application of GA3 was made by foliar sprays at concentrations of 0, 125, 250, 500 and 1,000 mg L -1. The length of leaves increased significantly when using GA3 at low concentrations, but leaf width decreased. The application of GA3 at 125 mg L -1 showed the best results for the promotion of flowering and flower quality of this orchid hybrid. In this treatment, about 50% of plants treated with GA3 flowered about 6-12 months before the...

Provedor de dados: 75
Autores: Pinho,Lucinéia de; Almeida,Anna Christina; Costa,Cândido A; Paes,Maria Cristina D; Glória,Maria Beatriz A; Souza,Rogério Marcos.
The physicochemical characteristics of the cherry tomato cultivated in organic and conventional production systems and harvested at either 30 or 45 days of cropping were evaluated using a randomized, 2x2 factorial design (2 cropping systems x 2 harvesting times) with five repetitions. The parameters analyzed were color, centesimal composition, total energetic value, carotenoids and bioactive amine content. Tomatoes harvested at 30 days had higher total soluble solid (TSS) content when grown conventionally, but when harvested at 45 days, both conventional and organic tomatoes had similar TSS values, probably due to increased N availability in the soil. Organic cherry tomatoes had higher contents of β-carotene, lycopene and bioactive amine. On the other...

Autores: GUERRA, A. F.; FIALHO, J. de F.; ROCHA, O. C.; EVANGELISTA, W.
RESUMO: Este trabalho objetivou avaliar o efeito de diferentes espaçamentos de plantas, em duas variedades de mandioca, sobre a produtividade e a qualidade do produto quando submetidos a quatro regimes de irrigação. Os espaçamentos de plantas utilizados foram 60*60;100*60*120*60 cm, e os valores de tensão de agua no solo, usados nos quatro ensaios, foram 33,60,100 e 500 kPa medidos a 10 cm de profundidade. Sempre que a tensão de agua no solo atingia os valores predeterminados, procedia-se à irrigação para elevar o conteúdo de agua na camada superficial de 35 cm até a capacidade de campo. As tenções de 33 e 60 kPa foram monitoradas por tensiômetros e as de 100 e de 500 kPa, por blocos de gesso. Verificou ? se redução linear da produtividade com o aumento da...

O risco de subprodutos indesejáveis &amp;#8203;&amp;#8203;da desinfecção com cloro em indústrias de produtos minimamente processados, juntamente com sua eficácia limitada, levou à busca de agentes alternativos. O objetivo deste estudo foi avaliar a eficácia dos óleos essenciais de capim-limão e alecrim-pimenta no controle da microflora natural de cenoura minimamente processada e, ao mesmo tempo, considerar seu impacto nas propriedades organolépticas do produto. Contudo, o uso de óleos essenciais de capim-limão e alecrim-pimenta resultou em cenouras minimamente processadas de baixa aceitabilidade, não sendo um tratamento recomendado nas concentrações testadas.

Forrageiras: principais fatores de antiqualidade.
Provedor de dados: 14
Autores: JERBA, V. de F.; MEDEIROS, S. R. de; FERNANDES, C. D.
A pecuária brasileira baseada em pastagens é uma das atividades econômicas mais importantes do Brasil, portanto são necessárias a manutenção e a ampliação de programas de melhoramento genético de forrageiras. Além de observar o desempenho agronômico do vegetal, é importante a determinação do seu valor nutritivo. Essa última característica é comumente determinada por análises bromatológicoas, mas, no entanto, existem fatores que limitam a ingestão e a digestão das forrageins que não são determinadas pelas análises convencionais, os quais são denominados de antiqualidade ou antinutricionais, os quais projudicam até mesmo a aceitabilidade da forragem pelos animais. Os fatores de antiqualidade são de natureza quimica ou estrutural, podendo ser determinados em...

A produção de couro no Centro-Oeste.
Provedor de dados: 14
Autores: CARDOSO, E. E.
Ao longo dos últimos 40 anos a pecuária bovina foi gradualmente migrando para as regiões Centro-Oeste e Norte do País, transformando a primeira no principal produtor nacional de carne e couro. Fruto dessa expansão, o País tornou-se o segundo maior produtor mundial de couro, atrás apenas dos Estados Unidos, que é o principal produtor. No entanto, a baixa qualidade do couro brasileiro e a falta de infra-estrutura para mudar esse quadro, mormente na região Centro-Oeste, impedem que o País torne-se mais competitivo no mercado internacional. Diante desses antecedentes, justifica-se plenamente a implantação, no Centro-Oeste, de um centro de tecnologia voltado para o couro, como forma de impulsionar a melhoria da qualidade dos couros produzidos na região. Com...

Since 1998, a growth and quality monitoring study of reared molluscs has been developped as part of a close collaboration between the Shellfish Research Laboratory of Normandy (IFREMER Port-en-Bessin, Calvados) and the SMEL (Syndicat Mixte d'Expansion du Littoral) Experimental Centre (Blainville, Manche). REMONOR (REseau MOllusque de NORmandie) is based on the experience gained through the national monitoring network REMORA, which protocol has been entirely applied. Adults and spat of Pacific oysters Crassostrea gigas were placed in 13 stations all along the oysters rearing areas of Normandy. These oysters had the same origin and history (i.e. age and weight) until they were dispatched on the 13 stations. 4 essential criteria were used to monitor rearing...

Salmoniculture marine : la collecte, une étape clé
Provedor de dados: 5
Autores: Knockaert, Camille.
For several reasons, the harvest stage is most important in aquaculture. Not properly managed, it may diminish efforts invested throughout the whole culture cycle. This operation consists in harvesting and in killing the fish for marketing purposes and must be achieved with care to optimizing the final quality of the product in terms of flavor, sanitary aspects and preparing it well for processing. Analysing the numerous complaints expressed by endusers concerning the quality of cultured salmon demonstates that the harvest stage is the main cause of these failures. Among the failures reported, we can quote the problems of "gaping" (disconnection of the myotomes in the fillets), of brown spots (spotlights of blood), of soft texture, discoloration and early...

The national REMORA network is targeted on the studies of growth, flesh quality and mortality of a sample of cupped oyster Crassostrea gigasdistributed on 9 stations along the coast of Normandy. As a better precision is needed for regional purpose, 7 new stations have been added. A total number of 16 stations is now sampled from Chausey to Meuvaines. Weak rates of mortality have been noticed in 2002 on both adults (7%) and spat (6 %). These rates are the weakest ever seen. The mortality rates in the Baie des veys were less than 10 %. This rearing area shows usually a much higher mortality level. Growth rates were noticed weaker than usual. They slowly decline from 1999. From Mach to December, the growth rate of adults has been computed to 0,21 %/day (for a...

The network named REMONOR (REseau MOllusqueNORmandie) aims to assess mortality, growth and tissue quality of the Pacific oyster, Crassostrea gigas, cultivated in Normandy over an annual cycle. This local network relies on the same material and methods as the national one named REMORA (REseau Mollusques Ressources Aquacoles). The study was carried out in 17 sites, which were distributed in the four basins where oyster rearing occurs in Normandy (West and East coast of Cotentin, Baie des Veys and Meuvaines). In 2003, a new site was added, which was located in the area of Ver-Sur-Mer (Calvados). The results obtained in 2003 showed a low annual mortality for adults (8%) as well as for juveniles (10%). Growth was also low for the two age classes of oyster...

Some methods for quantifying quality in the scallop Pecten maximus (L.)
Provedor de dados: 5
Autores: Maguire, Julie A.; Fleury, Pierre-gildas; Burnell, Gavin M.
(Not controled OCR) Because biological systems do not work in isolation, behavioral, biochemical, and physiological tests can give an overview of an individual's vital processes and reaction to stress. Two stress gradients were applied in this study, a short acute desiccation stress and a long-term density stress. These stress gradients were used to assess the usefulness of various techniques for quality assessment: namely, a standard salinity stress test, condition index, recessing speed of the scallop, adenylic energetic charge (AEC). and percentage carbohydrate content of the striated muscle. The results showed that AEC could be used effectively to measure the effect of a short-term stress. In the striated muscle. AEC levels were useful in...

This study aims to investigate the benefits associated with traceability and its relationship to quality. Market research has been conducted in Spain, Portugal, France, UK and Germany. The results show that the expected benefits for consumers related to traceability focus on food safety and quality. Relevant information about traceability should focus on the intrinsic quality attributes highly valued by consumers and food safety. Among them, it highlights the origin, the value of which has been highly appreciated by most consumers in different countries. As regards signalling, consumers rate labelling very favourably, which would have to offer all relevant information on the intrinsic quality attributes. The implementation of technology (e.g. QR) could...

Changes in Atlantic cod (Gadus morhua L.) sperm quality during the spawning season
Provedor de dados: 5
Autores: Rouxel, Catherine; Suquet, Marc; Cosson, J; Severe, Armelle; Quemener, Loic; Fauvel, Christian.
The biology of cod reproduction is well described in the scientific literature. However, sperm biology and spermatozoa management are poorly studied in this species. Because of its recent farming expansion, a better knowledge of cod gametes is becoming especially useful. This work aimed at establishing tools to study sperm biology in cod, and also investigated the existence of changes in cod sperm quality during the spawning period. We showed that sperm concentration could be assessed using spectrophotometry at 260 nm. Sperm motility significantly decreased after a 168-h storage at 4 degrees C. A 1:9 dilution of sperm in a non-activating medium (1/3 seawater and 2/3 freshwater, osmotic pressure: 360 mOsm kg(-1)) improved sperm storage. Sperm concentration,...

Nutritional components affecting skeletal development in fish larvae
Provedor de dados: 5
Autores: Cahu, Chantal; Zambonino, Jose-luis; Takeuchi, Toshio.
Marine fish larvae undergo major functional and morphological changes during the developmental stages and several factors can interfere with the normal development of larvae and affect fry quality. Skeletal malformations, such as spinal malformation-scoliosis, lordosis, coiled vertebral column-, missing or additional fin rays, bending opercle or jaw malformations, are frequently observed in hatchery-reared larvae. This paper reviews the effects of some nutritional components on skeletal development in larvae of a number of fish species. In the dietary lipid fraction, for instance, it was proven that the phospholipid concentration affected the spinal malformation rate in sea bass fed a compound diet from mouth opening onwards. Phosphatidylinositol, in...

The aim of this study was to investigate the impact of superchilling (-2 degrees C) on the evolution of Listeria monocytogenes and organoleptic characteristics of cold-smoked salmon samples. An Hadamard matrix experimental design was carried out on artificially inoculated samples stored at +4 degrees C for 10 d and at +8 degrees C for 18 d to know the influence of four factors: salt content, strain, cold stiffening and superchilling time, on the level of L.monocytogenes in cold-smoked salmon. The growth of L. monocytogenes in naturally contaminated cold-smoked salmon and the organoleptic properties were investigated under superchilling conditions. Superchilling (-2 degrees C for 28 d) had a limited impact on some of the organoleptic properties but the...

La densite, un critere de qualite applicable en ecloserie aux embryos de Pecten maximus (mollusque bivalve)
Provedor de dados: 5
Autores: Faure, Catherine; Devauchelle, Nicole; Dorange, Germaine.
The quality of the scallop embryos is determined by the spawners characteristics as well as by the external factors they support during the maturation and the spawning phases. All these parameters are not still well controlled during the artificial conditioning in the hatcheries. As a consequence, the quality of the embryos is drastically variable and with them, the larvae performances in terms of survival and growth rates. It would be interesting to get a simple and quick test which would allow the estimation of the spawns quality. The embryos density, evaluated by isopycnic centrifugation of Percoll medium, is well adapted to this objective. Actually, a centrifugation of embryos two hours after fertilization separates them in 3 stratum with their density...

ATP content and viability of spermatozoa drive variability of fertilization success in the Pacific oyster ( Crassostrea gigas )
Provedor de dados: 5
Autores: Boulais, Myrina; Soudant, Philippe; Le Goic, Nelly; Quere, Claudie; Boudry, Pierre; Suquet, Marc.
Fertilization of the oocyte is a critical process of sexual reproduction depending among other factors on spermatozoa functionality. Mitochondria participate in many crucial processes for spermatozoa motility and fertilizing ability. The Pacific oyster, Crassostrea gigas, is characterized by a high inter-individual variability of its reproductive success which has been shown to be partially due to the variability of gamete quality. The present study explored spermatozoa characteristics such as: i) relationships among mitochondrial functionality (ATP content, mitochondrial membrane potential (MMP), reactive oxygen species production); sperm viability (percentages of live, dying, and dead); and motility; and ii) their involvement in inter-oyster variability...

The network IFREMER/REMORA has watched every year, since 1993, from February to December, mortality, growth and quality criteria of two oyster class-size ("juveniles" of the first-year c1ass and "adults" of the second year c1ass), distributed among various stations of the French oyster areas. This has provided a quite standard and simple annual assessment of the rearing results, generally tallied with professional observations. From year to year, data series have been obtained, from which mean values (references), chronological trends or spatial differences can be analysed. Results in Brittany, from 1993 to 1998, show that, in a "normal" year, 30 g oysters grow to 60-80 g at the end of the year, with a mortality rate of 10-15%. Mortality occures mainly in...

Autores: Gremare, A; Amouroux, Jm; Charles, F; Medernach, L; Jordana, E; Nozais, C; Vetion, G; Colomines, Jc.
Gross sedimentation rates (GSRs) were monitored together with meteorological data and the main biochemical characteristics of the collected material (i.e. organic content, C, N, total proteins, carbohydrates, lipids and available proteins) over a three year cycle at a shallow station (18 m) of the Bay of Banyuls, France. GSRs were between 0.26 (11/04/92) and 317.75 gDW m(-2) d(-1) (18/02/94). They followed an annual cycle with low and relatively constant values during spring and summer and high, variable Values during fall and winter. During the study GSRs correlated poorly (state of the sea, precipitation) or even non-significantly (wind speed) with the main meteorological parameters. GSRs correlated negatively with the organic content of the material...

Trends in postmortem aging in fish: Understanding of proteolysis and disorganization of the myofibrillar structure
Provedor de dados: 5
Autores: Delbarre Ladrat, Christine; Cheret, Romuald; Taylor, Romuald; Verrez-bagnis, Veronique.
Introduction :  Quality attributes of fish flesh, including food safety, organoleptic features, nutritional quality and aptitude to industrial transformation, influence consumption and acceptability of fish as food. Fish sensorial changes and texture properties are closely linked to freshness. Along with ante mortem muscle biochemistry, postmortem biochemical processes are directly linked to final quality attributes. The understanding of postmortem mechanisms is a prerequisite for an accurate control of the quality of commercialized fish by the identification of objective markers or indicators. Postmortem tenderization is one of the most important quality attributes of fish muscle. Loss of freshness is due to a complex combination of biochemical, chemical...

Product differentiation and quality approach in the French market for oysters and mussels.
Provedor de dados: 5
Autores: Charles, Erwan; Paquotte, Philippe.
France is one of the world top producers of oysters and mussels by aquaculture with 140 000 tonnes of oysters, 60 000 tonnes of mussels and an ex-farm turnover accounting to 350 millions US$ in 1996. The French market is by far the largest one in Europe for oyster and is supplied entirely by domestic production, with very little external trade. On the contrary, the French market for mussel is a very competitive one, widely open to imports. Given the evolution of market conditions due to the development of supermarkets, to the competition of new value added products and to the modification of consumer's habits, the French oyster and mussel producers have started to implement various strategies of product differentiation and of quality approach. These...

At the end of its third year, the regional network for monitoring REMONOR, confirms the particularities of oyster from Normandy in matter of growth and quality. Results from 2 000 are globally very close of those from 1998. Mortality of adults reached 14% and juvenile 6% which represent a low death rate. For this year the most blow area is the Baie des Veys with 31% death rate at Géfosse. Observed growth this year had been weaker than the past two years despite the spring and automnal growth. At spring, the higher recorded growth rate on the West coast with 0.42% (regional average : 0.29%). This seasonal trend seems more and more obvious every year. Regarding the classification of the special oysters, despite the change of the standard, the Baie des Veys...

The monitoring network IFREMER/REMORA in Thau lagoon is assessing, on a yearly basis, mortality, growth and quality criteria distributed among 6 stations. Samplings are carried out in March, June, September and December. 2003 is a year with a very important mortality in Mèze and Marseillan area due to an anoxy and an anormal mortality at Bouzigues Nord in december. The growth rate is always better than others French oysters areas. Afnor index is high (beetwen 13.7 and 16.5 in december), so the totality of the oysters are classifed in "Spéciales". Polydora sp. Index is important but the initial stock was first infected. The valve quality is good, with no gelatine, except on Bouzigues South.

Risks of vaccination: a review
Provedor de dados: 80
Autores: Rashid,A; Rasheed,K; Asim,M; Hussain,A.
To be granted a product license, a vaccine must present adequate quality, safety and efficacy. Studies on these criteria often utilize target species in a laboratory setting. Vaccines that had been proven effective during laboratory analysis may not present the same features when sold on a large scale, after encountering field conditions, and furthermore, can even produce complications. Measures are already in place to detect adverse reactions as reported by veterinarians to manufacturers, so that vaccines under suspicion of failing can be identified and investigated. The present review article describes the main problems, specifically adverse reactions and lack of efficacy, that have been encountered following release of vaccines for general use.

Cambios de color en la piel del dorado (Mahi-mahi, Coryphaena hippurus) en relación a la formación de histamina
Provedor de dados: 20
Autores: Wood, C.D.; Camba, N.; Grijalba, M.
En el Ecuador se utiliza el cambio de color en la piel del dorado amarillo a blanco como indicador de la calidad. Se investigó este cambio en relación a la formación de histamina bajo varias condiciones. Luego de este estudio se concluyó que, en combinación a otros parámetros como olor y textura, el color de la piel puede ser útil para distinguir pescado de buena calidad (grado A) y pescado de calidad inferior (grado B). Sin embargo existen condiciones bajo las cuales es posible tener dorado no apto para consumo humano con piel amarilla y por eso siempre es recomendable revisar todas las características sensoriales en la evaluación de calidad. Este cambio de color no hace posible la distinción entre dorado con niveles significativos de histamina. Solamente...

Lutte contre le mildiou de la laitue (Bremia lactucae) sous abri froid : compte-rendu d'essai 2009
Provedor de dados: 21
Autores: Lambion, Jérôme.
Le mildiou de la laitue (Bremia lactucae) est la maladie la plus redoutée sur cette espèce, notamment en culture biologique d’hiver sous abris. En Provence, les dégâts sont très importants, parfois dès la pépinière, et entraînent de fortes pertes financières. Cette situation est due à deux facteurs principaux : d’une part au contournement récurrent des résistances génétiques par de nouvelles souches de Bremia (26 races déterminées à ce jour), et d’autre part à la faiblesse des méthodes de lutte biologique possibles contre ce champignon (notamment la faible efficacité des traitements à base de cuivre). Cet essai consiste en un test de produits alternatifs de différentes natures (extraits de plantes, produits minéraux...).

Interaktionen zwischen Anbaubedingungen, Pilzbefall, Backqualität und Mykotoxinbelastung in der ökologischen Weizenproduktion
Provedor de dados: 21
1. Feldversuche  Die Winterweizensorten Arina und Capo wurden im Versuchsjahr 2002/2003 auf insgesamt 12 Standorten im Ökologischen Anbau als Reinbestände und als Sortenmischung angebaut. Das Versuchsjahr war extrem trocken, weshalb kein relevanter Krankheitsbefall zu verzeichnen war. Die Erträge variierten je nach Standort von 26 bis 53 dt/ha wobei Capo deutlich ertragsstärker war als Arina. Die Mischung brachte im Schnitt 3% mehr Ertrag als erwartet und war im Ertrag deutlich stabiler. Dies war auf die stärkere Konkurrenzkraft der Sorte Capo an fast allen Standorten zurückzuführen.  Arina übertraf Capo signifikant im Rohprotein (RP) (12.9 versus 12.2%) und Feuchtklebergehalt (FK) (29.8 versus 25.3%), was auch im Backvolumen reflektiert wurde. Während bei...

Screening of micro-organisms for Venturia inaequalis control by means of DGGE
Provedor de dados: 21
Autores: Speksnijder, Arjen; Lombaers- van der Plas, Carin; Köhl, Jürgen.
Venturia inaequalis causes apple scab. The control of the disease in organic apple production depends on the use of copper which will be restricted in future for environmental reasons.   In the search for environmental friendly microbial biocontrol agents and stimulation of antagonistic populations in situ the molecular technique of DGGE fingerprinting can is applied. This fingerprinting technique allows to bypass culturing techniques and even can identify not yet culturable organisms.   Comparison of microbial fingerprints and pathogen development in the leaf samples during winter and spring has been performed to identify populations with antagonistic potential. Such potential antagonistic organisms can be further identified by their specific DNA...

Autores: Pfeiffer, B.
Different strawberry varieties, available from organic propagation at that time were, planted  in August 2004 and proofed about their suitability for organic cultivation, each variety was  tested with and without biodegradable mulch film. Within the early ripening strawberry  varieties ‘Clery’ had a middle yield and was susceptible for infections with leaf spot, losses  of plants by Verticillium were seldom. This variety should be planted early to reach enough  vigor in autumn. ‘Clery’ has an interesting potential in the phase of higher prices at the  beginning strawberry season. ‘Darselect’ ripened shortly before ‘Elsanta’, the yield was  lower, but the fruit-size bigger, so the picking could be done more quickly. ‘Elsanta’  showed in this trial under...

The two-spotted spider mite can be controlled by water
Provedor de dados: 21
Autores: Conte, Dr. Luca; Chiarini, Dr. Francesca.
The effects of a fogging system on the control of the two-spotted spider mite (Tetranychus urticae) were studied in greenhouse cultivation of eggplant, cucumber and strawberry during the period 1999-2006. At the beginning the pest and the phytoseiid predator Phytoseiulus persimilis were released on the crops and then observations were made on the development of the populations of both mites. Fogging system effects were found in terms of lowering the T. urticae population and hindering the growth of powdery mildew fungus. Furthermore there was a yield increase in the cases of strawberry and cucumber in 2001 but no negative impact on pest management was ever detected, particularly on the biological control of the melon aphid (Aphis gossypii) achieved using...

Prediction of grain yield of spring barley varieties by disease and growth characteristics from VCU testing
Provedor de dados: 21
Autores: Østergård,  H.; Kristensen, K.; Jensen, J.W.
Fifty spring barley varieties grown under organic as well as conventional growing conditions in experimental fields in four combinations of year and site were studied. The yield varied much within and between environments (years and sites) and systems. Further, the variation between varieties was substantially and it differed between different environments and systems. Associations between observed grain yield of these varieties and disease and growth characteristics assessed in the official conventional variety testing were compared between the organic and the conventional system. Using factorial regression analysis, the best model for predicting the observed grain yield each year from these characteristics the previous year was found. In this model, the...

Klippträda istället för svartträda – Icke-kemisk kvickrotsbekämpning i växande gröda
Provedor de dados: 21
Autores: Bertholtz, Erik.
Kvickrot (Elytrigia repens (L.) Desv. ex Nevski) är ett flerårigt ogräs som är vanligt förekommande i svenska odlingsmarker. Innan kemisk totalbekämpning med glyfosat var kvickrot ett vanligt problem i lantbruket. Ogräset kontrollerades då med intensiv jordbearbetning. Idag är kvickrot ett viktigt ogräs i ekologisk odling och i system med reducerad jordbearbetning. Dock måste kvickrot fortfarande anses vara ett problem i konventionella system eftersom glyfosat måste användas återkommande för att slippa konkurrenseffekterna från kvickrot. Detta arbete är ett delprojekt som ingår i ett större projekt som syftar till att utveckla ekologiska odlingssystem som inte är lika beroende av jordbearbetning för att kontrollera kvickrot som dagens system.

Simultaneous epidemic development of scald and net blotch on single leaf layers of a spring barley crop
Provedor de dados: 21
Autores: Vollmer, J.H.; Pinnschmidt, H.O.; Munk, L.; Østergård, H.
Background and objectives  Two pathogens growing on the same leaf compete for the same resources, i.e. space and plant nutrients. This may lead to density dependent disease development. The pathogens may also influence each other directly such that the influence of one on the other is more complex than a simple function of the area of the other pathogen. Different interaction types are, for example, competition, mutualism and exploitation. The importance of such interactions for epidemics of simultaneously occurring pathogens has received little attention. The objective of this study is to investigate the simultaneous epidemic development of Rhynchosporium secalis (causing scald) and Drechslera teres (causing net blotch) on spring barley under field...

Sheep grazing vs. cutting: regeneration and soil nutrient exploitation of the grassland weed Rumex obtusifolius
Provedor de dados: 21
Autores: Zaller, Johann G.
Broad-leaved dock (Rumex obtusifolius L., Polygonaceae) is an agronomically  important perennial weed causing decreases in pasture yields and fodder quality.  Non-chemical control measures for dock are often limited to frequent pulling and  cutting, additionally it is usually avoided by grazing animals. Here, the regeneration of  R. obtusifolius in a Rumex-infested grassland grazed by a sheep breed that explicitly  feeds on dock (Ovis aries L. cv. East Prussian Skudden) was compared to cutting.  Therefore, regeneration of 90 R. obtusifolius plants of three different size classes was  monitored in three plots during three grazing and cutting cycles. Plant height and  number of fruit-stands of regrown R. obtusifolius was significantly lower, number of...

More and more organic farmers lift potatoes which are damaged by wireworms (Agriotes spec. and Hemicrepidus niger). A nationwide status quo-analysis was carried out by the Chamber of Agriculture of North Rhine-Westphalia in 2002 and 2003. The survey included an intensive literature research, a questionnaire with 26 questions, on-site assessments, and on-farm trials. It was noticed that a long period of grass-clover cultivation in the crop rotation had a negative effect on the quality of potato tubers. Peas and lupines seemed to be the better pre-crops for a good quality of tubers in contrast to field beans and red clover. An autumn fertilization with manure resulted in a low feeding damage on potatoes by wireworms. Many perennial weeds some like...

Many growers of organic strawberry and raspberry have large losses in yield and reduced quality of their products because of insect damage. For many insects species pheromones and host plant volatiles are of major importance in mate finding and host plant location. In this project we want to extend our knowledge of these systems to develop effective control measures to control these pests in organic crops. The focus will be on the strawberry blossom weevil, the European tarnish plant bug and the raspberry beetle.

Efficacy testing of novel organic fungicides and elicitors: from the lab to the field
Provedor de dados: 21
Autores: Schaerer, Hans-Jakob; Amsler, Thomas; Thürig, Barbara; Tamm, Lucius.
Novel organic fungicides and elicitors against downy mildew on grapevines were evaluated on grapevine seedlings in a series of indoor screening experiments under controlled conditions and, if they have shown a good efficacy indoors, in a screening vineyard under field conditions.   From 39 products tested under controlled conditions 10 were further examined under field conditions.  All of the new products tested under field conditions showed at least partial efficacy. However, the efficacy was not good enough to protect grapevine plants sufficiently from downy mildew. For a complete re-placement of copper in plant protection against downy mildew on grapevine in organic agriculture, additional new products are needed.

Biodiversité fonctionnelle en maraîchage biologique : comment favoriser les punaises prédatrices ? Compte-rendu d'essai 2008
Provedor de dados: 21
Autores: Lambion, Jérôme; Amour, Clément.
La biodiversité fonctionnelle consiste à implanter autour des cultures des espèces végétales qui vont attirer, héberger, nourrir les insectes auxiliaires indigènes (notamment les punaises prédatrices), participant au maintien des populations de ravageurs sous le seuil de nuisibilité économique. L'objectif est donc de transposer cette technique pour améliorer la lutte contre les aleurodes et les acariens tétranyques, qui sont parmi les principaux ravageurs sous abri dans le Sud de la France. Les espèces végétales les plus intéressantes globalement sont donc, dans l’ordre : Calendula officinalis, Dittrichia viscosa, Geranium robertianum, Achillea millefolium et Phacelia tanacetifolia.

Methods for seed treatment in organic farming
Provedor de dados: 21
Autores: Koch, E.; Schmitt, A.
Abstract – Seed-borne diseases are increasingly becoming important in organic farming, therefore effective seed treatment methods are urgently needed. Physical methods have efficacy against a number of seed-borne pathogens, but may have adverse effects if applied at too high intensity. Thermal treatment in water has the widest application. To control the loose smuts of wheat and barley it is still the only available non-chemical sanitation method. Other physical treatment methods with practical relevance in cereals are hot humid air and electron treatment. Hot water treatment is also known to control different seed-borne pathogens of vegetables. Various preparations of microorganisms, plant extracts and other agents of natural origin have been and are...

Am Kompetenzzentrum für ökologischen Gemüsebau in Bamberg (Bayr. Landesanstalt für Wein- u. Gartenbau) fand 2008 ein Vergleichsanbau von 20 supersüßen und zwei normalsüßen Sorten Zuckermais statt. Weltweit gibt es nur fünf Züchter von Zuckermais, von denen sich vier in den USA befinden. In Anbetracht der räumlichen Konzentration der konventionellen Maiszüchtung und der dadurch steigenden Gefahr der gentechnischen Verunreinigung galt den fünf Sorten aus Ökozüchtung (dabei Probesaatgut von drei Sativa-Selektionen) ein besonderes Interesse. Bewertet wurden marktfähiger Ertrag und Süße.

The effect of companion planting on the abundance of pest complex and its parasitism rate on white cabbage
Provedor de dados: 21
Autores: Kaasik, R.; Kovács, G.; Pehme, S.; Veromann, E.
The findings of this paper could help to develop and maintain a sustainable cabbage production by the enhancement of natural pest control with the help of companion planting. Our results indicate that Lobularia maritima (Brassicaceae) could be used to attract pests of cruciferous plants away from the crop.  Centaurea cyanus (Asteraceae) and Fagopyrum esculentum (Polygonaceae) could be used to suppress pests of cruciferous crops and to increase parasitism rate by fostering parasitoids.

Entomopathogenic nematodes for biological control of codling moth
Provedor de dados: 21
Autores: Peters, A.; Katz, P.; Elias, E.
Entomopathogenic nematodes are often found naturally infecting codling moth larvae. The  effect of an autumn treatment with S. feltiae on the fruit damage in the following summer  was evaluated by treating 4 different apple orchards in October 2004 and 2005 at  application rates of 3.75; 2 and 1.5 billion nematodes in 4000 l / ha. In three of the treated  orchards, one treated with 3.75x109 nematodes/ha the other two treated with 2e9  nematode/ha, reduction in fruit damage was around 50%. In the most heavily infested  orchard, which was treated with 1.5x109 nematode/ha only 33% reduction in fruit damage  was achieved. Compared to previous studies, this was the first assessing the effect on the  fruit damage in the summer following the treatment rather than...

We have studied the emission of volatile organic compounds (VOCs) from young strawberry plants, cultivars Polka and Honeoye, after feeding by several strawberry herbivores under laboratory conditions. VOC profile of strawberry plants is highly dominated by green leaf volatiles (GLVs), which are released also due to mechanical damage. Our results reveal that strawberry has potential for inducible VOC defence, and this encourages testing the attractiveness of these strawberry VOCs to predatory mites.

Finger Millet Growth and Nutrient Uptake Is Improved in Intercropping With Pigeon Pea Through “Biofertilization” and “Bioirrigation” Mediated by Arbuscular Mycorrhizal Fungi and Plant Growth Promoting Rhizobacteria
Provedor de dados: 21
Autores: Saharan, Krishna; Schütz, Lukas; Kahmen, Ansgar; Wiemken, Andres; Boller, Thomas; Mathimaran, Natarajan.
Legume-cereal intercropping is well known in traditional dry land agriculture. Here, we tested whether finger millet, a shallow-rooted cereal, can profit from neighboring pigeon pea, a deep-rooted legume, in the presence of “biofertilization” with arbuscular mycorrhizal fungi (AMF) and plant growth-promoting rhizobacteria (PGPR), under drought conditions. We conducted a greenhouse experiment using compartmented microcosms. Pigeon pea was grown in a deep compartment with access to a moist substrate layer at the bottom, whereas finger millet was grown in a neighboring shallow compartment, separated by 25-µm nylon mesh, without access to the moist substrate layer. In the presence of a common mycorrhizal network (CMN), with or without PGPR, a drought condition...

Autores: Østergård, H.; Kristensen, K.; Jensen, J.W.
Six 3-component variety mixtures of spring barley and their component varieties have been grown in 17 different environments (3 years, 3 locations, 3 different growing systems). For three of the six mixtures, the grain yield was significantly higher than the average yield of its components; in none of the mixtures it was significantly lower. The variation in grain yield over environments of all variety mixtures was compared to the variation of all component varieties. The six mixtures were on average more stable than the 14 component varieties grown in pure stands with respect to actual yield as well as to rank values of yield.

Grassland management, soil biota and ecosystem services in sandy soils
Provedor de dados: 21
Autores: Eekeren, N. van.
Recent legislative restrictions on the use of fertilizers and irrigation, and a quest for sustainable farming systems have drawn renewed attention to the functioning of the soil and the ecosystem services it provides. Soil biota play an important role in the provision of these ecosystem services, which may be influenced by grassland management. The two objectives of this thesis were 1) to gain insight into the effect of different grassland management measures on soil biota in sandy soils; and 2) to explore the effect of grassland management on the ecosystem services provided by soil biota.

During the last years damage caused by plant parasitic nematodes in organic field vegetable farming has been observed with increasing attention. A general inquiry was started on farms with nematode problems to collect information about infestation, crop rotation and control strategies. Soil samples from 207 vegetable fields were taken from 55 farms in Germany and the detected nematodes were analysed. Seventeen different genera of plant parasitic nematodes were found. Nematodes of the genus Pratylenchus were found on 90 % of Meloidogyne on 50 % of the analysed fields - these two are the most important genera that damage vegetables. More than half of the infested fields were of sandy soils. Yield reductions of 50 % could be observed on 40 % of the fields...

In Switzerland, transplants for organic vegetable growing have been fertilised traditionally with slaughterhouse by-products. In autumn 2000, the Swiss government restricted the use of such products because of the BSE crisis. To maintain the production of organic transplants, alternative fertilisers needed to be tested. Eleven alternatives to horn powder (standard fertiliser) were selected based on the organic standards of the European Union, including feather powder (as an animal based product without BSE risk). The products were mixed with a standard growing media for organic transplants in a concentration of 300 mg nitrogen L-1 growing media.

Vanaf 2007 wordt nagegaan of de wortelvlieg in het veld te beheersen is door het toepassen van twee verschillende sterk geurende oliën. De volwassen wortelvlieg vindt een peenperceel met behulp van de geuren die de planten afscheiden. De vraag is of de geur van zo’n peenperceel gemaskeerd kan worden met sterk ruikende plantaardige oliën zodat de wortelvlieg dit perceel niet meer kan vinden. In 2008 waren er aanwijzingen dat uienolie de wortelvliegaantasting kan verminderen.     In 2009 zijn op 6 peenpercelen en een perceel wortelpeterselie demonstraties aangelegd om de wortelvliegaantasting te beperken.

Drahtwürmer können durch Lochfraß an Kartoffelknollen das gesamte Erntegut vermarktungsunfähig machen. Immer mehr ökologisch wirtschaftende Landwirte ernten Kartoffeln, die durch Drahtwürmer geschädigt sind. Daher wurde an der Landwirtschaftskammer Nordrhein-Westfalen eine bundesweite Status-quo-Analyse zur Drahtwurmproblematik im Ökologischen Kartoffelanbau und 20 Praxiserhebungen mit Kartoffelbonituren durchgeführt.    Insgesamt wurden Betriebs- und Flächendaten von 46 Betrieben und 121 Flächen aus 9 Bundesländern ausgewertet. 86% der Betriebe werden seit mehr als 10 Jahren ökologisch bewirtschaftet. 51%...

Optimising nutrition in organic tomato production
Provedor de dados: 21
Autores: Thorup-Kristensen, Kristian.
The abstract describes experiments with different cropping systems for organic greenhouse production of tomatoes. In this experiment two main questions are adressed. As greenhouse tomato production is a very intensive monoculture production, problems with nutrient supply and balances are expected, and problems with soilborne pests and diseases are widespread. To counter such problems, we compare the normal method of soil grown tomatoes with systems where tomatoes are grown in compost filled boxes. This allows to control nutrient losses and prevent carry over of diseses and pests in the soil. We also study an intermediate system, where where tomatoes are established in compost filled boxes, but the roots are allowed to develop also in the soil outside the...

Green Breeding: Bioimpuls Programme 2009-2013  -  Perspectives on  Phytophthora-resistant potato varieties
Provedor de dados: 21
Autores: Scholten, Olga E.; Lammerts van Bueren, E.T.
The heavy outbreaks of Phytophthora in 2007, and again in 2012, reconfirmed the need for resistant potato varieties for the organic sector. Until recently no such varieties were available. In 2009 the Bioimpulsprogramme was launched to give more priority to breeding organic, Phytophthora-resistant varieties. In this 10-year programme, wild potato species are crossed with cultivated potato to develop new resistant varieties. Although this classical breeding strategy is a long road, the advantage is that you can select for multiple traits along the way. This brochure presents the results of the first four years of the programme.

Innate and learned olfactory attraction to flowering plants by the parasitoid Cotesia rubecula (Marshall, 1885) (Hymenoptera: Braconidae): Potential impacts on conservation biological control
Provedor de dados: 21
Autores: Fataar, Shakira; Kahmen, Ansgar; Luka, Henryk.
In conservation biological control, flowers can be used to increase the biological control potential of parasitoids, which benefit from the offered food sources. Besides exhibiting exploitable nectar, flowers should preferably be olfactorily attractive, as highly attractive flowers are easily located, reducing the time spent searching for food and subsequently increasing the per capita host searching efficiency. In this study we thus focused on the olfactory attractiveness of Fagopyrum esculentum Moench (Polygonaceae), Centaurea cyanus L. (Asteraceae) and Vicia sativa L. (Fabaceae) to Cotesia rubecula (Marshall, 1885) (Hymenoptera: Braconidae), a larval parasitoid of the cabbage pest Pieris rapae (Linnaeus, 1758) (Lepidoptera: Pieridae). With a Y-tube...

Fugleskader i majs - kan der gøres noget?
Provedor de dados: 21
Autores: Schou, Anders.
Der gives ingen lette løsninger på problemet med fugleskader i majs. Det skal dog ikke hindre os i at lave forsøg på at afværge fugleskaderne. Skaderne sker ved at fugle finder og æder de nysåede majskerner, så længe de stadig indeholder oplagsnæring. Iværksætter man ikke foranstaltninger til at afværge fugleskader kan fuglene æder rydde store arealer af majsmarken. Fugleskader kan på visse lokaliteter opleves som den største udfordring og det største problem ved dyrkning af økologisk majs.

Peach orchard protection strategies and aphid communities: Towards an integrated agroecosystem approach
Provedor de dados: 21
Autores: Penvern, Servane; Bellon, Stéphane; Fauriel, Joël; Sauphanor, Benoit.
Aphid populations, including a widespread pest, Myzus persicae, are known to be affected by cultural practices, plant growth and natural regulation, but their control in orchards most frequently relies on regular treatments aiming to avoid direct damage and virus transmission. This study aimed first at characterising farmers’ management strategies towards aphids and, secondly evaluating them in terms of efficiency and impact on aphid natural enemies from 19 organic and conventional fruit farms in south-eastern France. Comprehensive variables made it possible to differentiate four strategies: intensive, optimised, input-substitution and integrated. The more integrated the strategy, the more diverse and abundant the aphids. The two most effective strategies...

Olfactometer screening of repellent essential oils against the pollen beetle (Meligethes spp.).
Provedor de dados: 21
Autores: Daniel, Claudia.
Essential oils can have an impact on pollen beetle (Meligethes spp.) host plant location behaviour. Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study that compared five different essential oils (Mauchline et al., 2005). However, lavender oil is one of the most expensive essential oils – a fact that could seriously hamper on-farm implementation of this strategy. To find a cheaper essential oil with comparable efficacy to lavender oil, we compared the essential oils of Mentha arvensis, Eucalyptus globulus, Melaleuca alternifolia, Citrus sinensis, Citrus paradisi, Citrus limon, Juniperus mexicana, Abies sibirica, Illicium verum, Gaultheria procumbens, Cymbopogon flexuosus, Syzygium aromaticum, and Litsea...

Thinning trials with lime sulphur in comparison to other products were carried out for 4 years in an ‘Elstar orchard’ at the OVB Jork in Northern Germany. Beside the yield, the influence on fruit size, colour, russet-ting and return bloom of treated trees were observed. Mechanic thinning was too strong and had other negative effects. Thinning with potato meal and coconut soap had no effect. Organic oil (Telmion) reduced the yield between 0 and 20%. Lime sulphur reduced the yield 0 – 40% in comparison of the concentration and the number of applications. There were great fluctuations from year to year. In conclusion lime sulphur gives the best results, but the variation from year to year is not acceptable for a practical advising in the northern area of...

Amara ovata und A. similata (Coleoptera, Carabidae), zwei  phytophage Laufkäferarten in Rapsfeldern
Provedor de dados: 21
Autores: Luka, Henryk; Pfiffner, Lukas; Wyss, Eric.
Amara ovata und A. similata, zwei im Adultstadium phytophage Laufkäferarten, wiesen in Rapskulturen im Vergleich zu Winterweizenflächen und ökologischen Ausgleichsflächen (Buntbrache und extensiven Wieslandstreifen) in der Nähe von Basel ein mit TRichterfallen gemessene, hohe Aktivitätsdichte auf. Handfänge und Beobachtungen auf fünf anderen Rapsfeldern in der Umgebung von Basel zeigten, dass Amara ovata und A. similata Schoten, Samen und Blüten der Rapskultur fressen. Aufgrund der nahen Verwandtschaft des Rapses mit anderen Brassicaceen nehmen wir an, dass Raps für A. ovata und A. similata eine bevorzugte Nahrungsquelle darstellt. Ob dadurch ein wirtschaftlicher Schaden entsteht, ist zurzeit noch nicht klar. Ein stärkerer Befall ist in der Nähe von...

Cultivating a diverse wheat population suitable for low-input and organic farming
Provedor de dados: 21
Autores: Caldbeck, Janie.
The Population produces more stable yields than those of the parent varieties due to more efficient use of soil nutrients and water, and lower plant disease and pest levels. When compared to the parent varieties, it produces yields of higher quality; increased protein content, improved hardness, good baking quality, comparable nutrition levels, and it is suitable for animal feed.  Practical recommendation  • The Population is most suitable for growing in low input or organic systems (under high input conditions it maintains its stability, but could yield significantly lower than pure line varieties).  • It is able to adapt to changing environmental and weather conditions and cope with variation in diseases and weeds. To further increase crop resilience,...

Autores: Gronle, Annkathrin; Böhm, Herwart.
The infestation of peas by aphids and moths was assessed in winter pea sole crops and compared to spring pea sole and winter pea-triticale intercrops. The field experiments were conducted in Northern Germany in the growing seasons 2009-2011. The maximum number of pea aphids per plant and the percentage of attacked plants were lower in semi-leafless and normal-leafed winter pea sole crops than in semi-leafless spring peas. Pea moth larvae damaged 6-32 % of seeds in winter peas and 40-55 % of seeds in spring peas. Winter pea-triticale intercropping reduced the attack of pea aphids, whereas no beneficial effect of intercropping was observed concerning moth-damaged peas. Owing to the earlier maturity, winter peas were less susceptible to pea pest attacks than...

Snabbare uppkomst och knölutveckling i ekologisk potatisodling genom en utvecklad förgroningsteknik
Provedor de dados: 21
Att odla potatis ekologiskt är mycket svårt och detta märks genom att arealen ekologiskt odlad potatis inte ökat utan snarare minskat under de senaste två åren. Det stora problemet för odlingen är risken för bladmögelangrepp. Det finns inga riktigt verkningsfulla bekämpningsmetoder att tillgå och de medel som finns kan i bästa fall fördröja angreppet någon vecka.        De mest verkningsfulla åtgärderna i dagens ekologiska potatisodling är att:         * Välja sorter som är motståndskraftiga mot bladmögel.    * Vidta åtgärder för att få en så tidig och snabb start av odlingen så att knölbildning och knöltillväxt kommer igång tidigt, t ex genom förgroning.

Autores: Schleuß, Uwe.
Zusammenfassend lässt sich nach den in Berlin (7. Fachgespräch zum Pflanzenschutz im ökologischen Landbau) vorgestellten Ergebnissen feststellen, dass momentan auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau noch nicht verzichtet werden kann. Um die Umweltauswirkungen auf Boden und Gewässer so gering wie möglich zu halten, muss die Aufwandmenge deutlich reduziert werden. Andererseits muss natürlich die fungizide Wirkung erhalten bleiben.  Ein Durchbruch beim Ersatz von Kupferpräparaten ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Deshalb ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen.

Prämunisierung (cross protection) als neue Strategie zur Bekämpfung von Phytoplasmosen im Obstbau am Beispiel der Apfeltriebsucht
Provedor de dados: 21
Autores: Schneider, Bernd; Jelkmann, Wilhelm.
Cross-Protection, ein Verfahren in dem Pflanzen durch Vorinfektion mit einem avirulenten Erregerstamm geschützt werden sollen, wurde als neue Methode zur Bekämpfung der Apfeltriebsucht erprobt. Gewächshausversuche mit Catharanthus roseus und Freiland-versuche mit Malus x domestica wurden durchgeführt, indem Versuchspflanzen zuerst mit dem avirulenten oder virulenten Stamm infiziert, und anschließend mit dem jeweils anderen Stamm zweitinfiziert wurden. Die Entwicklung der Erregerstämme wurde durch real time-PCR Analysen verfolgt. In den C. roseus Versuchen unterdrückte der avirulente Stamm 1/93 den virulenten Stamm 12/93, selbst wenn dieser zuerst vorhanden war. Die Ergebnisse der Freilandversuche waren nicht so einheitlich. In einem Versuch verhielten sich...

Das Anbaukonzept Weite Reihe bei verschiedenen Druschkulturen unter   Berücksichtung des Vorfruchtwertes
Provedor de dados: 21
Autores: Becker, Konstantin; Leithold, Günter.
Different row distances (12,5 cm vs. 50 cm) and leguminous underseeds have nor-mally little effect on of grain crop yield. When the main crops are strongly influenced by weed a higher yield can be achieved with the help of the wide-row-system. The crop quality can also be improved, for example the baking performance of winter wheat. The higher preceding crop value of wide-row-system with underseed can be demonstrated by potatoes.

Influence de la qualité des composts et de leurs extraits sur la protection des plantes contre les maladies fongiques
Provedor de dados: 21
Autores: Larbi, Mohamed.
Le potentiel suppressif de certains composts et de leurs extraits sur les maladies telluriques ou foliaires a souvent été démontré. L’efficacité des composts et/ou des extraits varie en fonction du type de compost et du système plante hôte-pathogène. Les raisons de cette variabilité demeurent encore en grande partie méconnues. De plus, les mécanismes d’inhibition des pathogènes par les composts et/ou les extraits de composts restent encore insuffisamment explorés. Une meilleure connaissance des paramètres influençant les propriétés phytosanitaires des composts et de leurs extraits est donc indispensable afin de pouvoir optimiser leur utilisation pour lutter contre les maladies des plantes.  Les objectifs du présent travail visent (i) la caractérisation des...

Autores: Singer, Christoph; Cergel, Sylvia.
Die einzige derzeit bestehende, voll wirksame und zugelassene Pflanzenschutzmaßnahme gegen verschiedene Schadpilze im Ökologischen Landbau sind Zubereitungen auf der Grundlage von Kupferverbindungen. Dies führt jedoch zur Anreicherung dieses Schwermetalls im Boden, was ab gewissen Konzentrationen zu toxischen Effekten führen kann.  Eine Herangehensweise im Ökologischen Landbau ist es, die natürlichen Widerstandskräfte der Pflanzen gegen Pilzinfektionen zu unterstützen und zu stärken. Das Ziel dieser Studie war es, das Potenzial von Traubenkernextrakten zu untersuchen, um die Pflanzen im ökologischen Weinbau gegen den Falschen Mehltau (Plasmopara viticola) und im ökologischen Landbau gegen weitere Schaderreger, wie den Erreger der Kraut- und Braunfäule...

Control of pollen beetle in organic farming with plant protecting  agents
Provedor de dados: 21
Autores: Humphrys, Clay; Jossi, Werner.
Pollen beetle (Meligethes spp.) is a major yield-limiting factor in organic oilseed  production. Currently there are no effective methods available to control this beetle in  organic agriculture. From 2006 to 2008 work was carried out at Agroscope ARTReckenholz  to find suitable organically compatible plant protecting agents which are  effective against the beetle. A partial reduction in beetle infestation was observed  when liquid manure, lavender oil and rapeseed oil was applied. Dusting agents such  as ash and substances containing silicate (stone meal) were very efficient, almost  completely removing the beetle after application. However, beetle infestation  increased again after one or two days following application. Dusting substances in  combination...

Klimaschutz auf Kosten des Bodens?
Provedor de dados: 21
Autores: Beste, Dr Andrea.
The current cultivation practice of conventional energy plant cropping does not increase biodiversity as it was announced by politics. Beyond that it does not minimize pesticide and  mineral manure application - quite the contrary.  It is a great challenge for the organic production of energy plants to connect humus balance with the use of bio-energy. First of all the sustainable use of liquid biogas manure must be queried regarding the nutrition quality of soil life.

Aerated compost tea (ACT) to improve soil biology and to act as a biofertiliser/biofungicide
Provedor de dados: 21
Autores: Amos, Dominic.
There is a growing body of evidence supporting the benefits of aerated compost tea (ACT) application, but not all studies have shown this conclusively. Compost tea application helps build healthy soils which can lead to benefits for the crop including improved crop health and nutrition, improved crop quality, as well as growth promotion and plant protection through pathogen suppression. Additionally ACT may also help crops cope better with abiotic stress factors such as drought.  Practical recommendation  • Exact methods of composting and compost tea making (aerobic vs anaerobic) are open to debate, but this practice abstract will focus on the method for producing aerobic compost tea.  • The most important step is to produce mature, well aerated compost...

Obwohl der Flug der Rapsglanzkäfer im Jahr 2008 schon im Februar einsetzte, blieben die Käfer  an den meisten Standorten unter der Schadschwelle. Die kühle Witterung bis Ende April  bremste die Aktivität der Käfer. Ende April waren bereits die ersten Rapsblüten geöffnet, sodass  die Rapsglanzkäfer kaum noch Schäden verursachen konnten. Zu kritischen Situationen kam  es in nur warmen Lagen mit schwerem, kühlen Boden (Fricktal): Die warmen Temperaturen  sorgten für eine starke Käferaktivität, während die kühlen Böden das Pflanzenwachstum und  die Blütenentwicklung bremsten.

To examine the use of low energy electrons as a method of seed dressing in ecologi¬cal agriculture, especially concerning its influence on seed vitality, samples of wheat, rye and barley were investigated by testing germination vigour under cold stress and by Bio crystallisation methods. Lowered germination speed indicated a decrease of seed vitality. Alterations of growth, like disturbance of gravitropism and an increased root:leaf ratio prove a significant impairment of the embryo by electron treatment. Results of biocristallisation and capillary dynamolysis indicate a loss of vital quality.

Clover fatigue - a reason for precaution in organic farming?
Provedor de dados: 21
Autores: Serikstad, Grete Lene; de Boer, A.; Magnusson, C.
Different species of fungi and nematodes cause clover fatigue. The literature review shows that there is a lack of knowledge about the status of clover fatigue in Norway. Samples from fields with clover/grass ley on organic farms in Norway demonstrated the presence of plant parasitic nematodes (Serikstad and De Boer 2013).   High densities of fungi and nematodes can impair the growth of legumes. Intensive use of clover in organic farming systems and a warmer climate are factors that indicate a need for attention to increased occurrence of diseases and pests in clover (Brandsæter et al. 2006). Problems with growing legumes will influence the nitrogen supply and economy in organic farming negatively.

The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0,1 and 0,2 %(w/v) and tested for their antifungal activity against the three fungi. In addition, the fungi were cultivated in a medium containing a commercial fungicide in the concentration of 0,2 % (w/v). Both of the phenolic concentrations inhibited the growth of all three fungi with the higher being more effective. It resulted in a four-fold reduction of the mycelial growth rate of A. solani and F. culmorum. The present...

Påvirker høstetid for gras innholdet av gunstige fettsyrer i økologisk melk?
Provedor de dados: 21
Autores: Adler, Steffen A.; Randby, Åshild T.
Effekten av høstetid for økologisk eng i Nord-Norge på sammensetning av fettsyrer i melk ble undersøkt i et fôringsforsøk med melkekyr. Tidlig høsting av økologisk eng økte ytelsen og protein% i melk. Normal høstetid ga høyere fett% og en antatt helsemessig gunstigere sammensetning av melkefettet. Dette skyldtes bedre forhold mellom mettet og umettet fett samt mer CLA og transvaccensyre (C18:1t11). Innholdet av alfa-linolensyre (C18:3c9,12,15), og forholdet mellom omega-6 og omega-3 fettsyrer var gunstigst i melk fra tidlig høsta gras.

Exploit biodiversity in viticultural systems to reduce pest damage and pesticide use, and increase ecosystems services provision: the BIOVINE Project
Provedor de dados: 21
Autores: Rossi, Vittorio; Berbegal, Monica; Armengol Forti, Josep; Kehrli, Patrik; Ranca, Aurora-Maria; Širca, Saša; Wipf, Daniel.
Organic vineyards still rely on large external inputs to control harmful organisms (i.e., pests). The BIOVINE  project aims to develop natural solutions based on plant diversity to control pests and reduce  pesticide dependence. The capability of plants of increasing the ecosystem resistance to pests and invasive  species is a well-known ecosystem service. However, monocultures (including vineyards) do not  exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased  plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots, edgings)  vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes,  fungi, nematodes), and foliar...

Der Einsatz von natürlichen Feinden ("Biocontrol-Organismen") schützt Kulturpflanzen wirkungsvoll vor Krankheiten und Schädlingen, bei minimalen Gefahren für Mensch und Umwelt. Bei der Zulassung sind solche Verfahren den synthetischen Pestiziden gleichgestellt, und die Anforderungen sind nicht an ihre Besonderheiten angepasst. Dadurch wird das Zulassungsverfahren unnötig verteuert und verlangsamt, was die Markteinführung dieser Verfahren bremst.

Provedor de dados: 21
Autores: Böhm, Herwart; Cerny, Dirk.
The effects of different plant protection treatments on foliar infestation by Phytophthora infestans and on tuber yield were tested in field trials from 1999 to 2001 under organic farming conditions. Foliar treatments with plant extracts of Potentilla erecta, Salvia officinalis, seaweed extracts, potassium oleate, some other plant vigorisers and combinations with an adjuvant as well as copper hydroxide resulted in different Area Under Crop Health Curves and tuber yield increase. Experiments were conducted at an ecologically-managed farm in the North of Germany (near Hamburg) on a sandy soil or loamy sand (pH 5.2 – 5.7) with the possibility of sprinkler irrigation. In all field trials copper hydroxide showed the lowest AUCHC and the highest yield...

Provedor de dados: 21
Autores: Schlötelburg, Annika; Wolff, Christian; Plekat, Alexandra; Wittmann, Christian; Jacob, Jens.
Feldmäuse (Microtus arvalis) können schwere Schäden in der europäischen Landwirtschaft verursachen und werden bei Bedarf mit Rodentiziden bekämpft. Nicht-chemische, großflächig anwendbare Alternativen stehen nicht zur Verfügung, was besonders im ökologischen Anbau ein Problem ist. Potenziell geeignete nachhaltige Methoden wurden im Labor entwickelt und in Feldversuchen an Feldrändern angewendet: 1) Pflugfurche mit Repellentien auf abbaubarem Trägermaterial (Dispenser); 2) Pflugfurche mit „Selbstbedienungsfallen“ für Prädatoren, die mit einem attraktiven Feldmaus-Köder bestückt sind.  Eine am Markt verfügbare Selbstbedienungsfalle ist die Standby-Box (Andermatt Biocontrol AG). Dieser Fallen-Typ wurde mit der im Projekt entwickelten Fangwanne verglichen, die...

Oospores of Phytophthora infestans in soil provide an important new source of primary inoculum in Finland
Provedor de dados: 21
Autores: Lehtinen, Ari; Hannukkala, Asko.
There have been numerous indications since the 1990s that oospore-derived primary infections play an increasing role in the epidemiology of potato late blight. The aim of this study was to verify that oosporederived epidemics actually occur in Finland. For this purpose, 20 suspected foci of oospore-derived potato late blight were scouted in 2000–2002. All of these were located in fi elds in which late blight had been observed in at least one of the four previous years. Primary symptoms in these foci occurred always on the lowest leaves near or touching the ground. Leafl ets typically showing numerous primary infections or lesions were in direct contact with the soil. In the former, oospores were observed after incubation. Soil samples from two experimental...

Vermeidung und Reduktion von Möhrenfliegenschäden im  Ökolandbau
Provedor de dados: 21
Autores: Herrmann, Farina; Buck, Holger; Liebig, Nadine; Hommes, Martin; Saucke, Helmut.
The carrot fly Psila rosae is a major pest in organic carrots. Damage strongly depends  on local factors and is often found when cropping intensity is high. However, limited  field site availability may require growing carrots close to crop sites of preceding  years. Here, results of the first two years show carrots may be protected from  infestation using trap crops (also carrots) to bind and actively reduce the local P. rosae  population. To protect the main carrot field, pair wise arrangements of carrot strips  were sown 1) directly at the previous year carrot field and 2) close to the main field to  protect the present carrots. During the first generation a mean sum of 36 and 62 flies/  trap in 2007 and 2008 respectively were monitored with yellow...

Better Organic Bread: Integrating Raw Material and Process Requirements for Organic Bread Production
Provedor de dados: 21
The UK organic wheat crop, of about 15,000 hectares, is rarely able to consistently provide flour of suitable quality to meet the needs of the baking industry. As a result, more than 50% of the requirement for wheat in the organic bread market is imported.   This project seeks to address the constraints to the expansion of the market for organic bread produced from wheat grown in the UK. This will be achieved by identifying the effect of agronomic practices on the protein content and quality of organic wheat. The work will optimise the interaction of raw material characteristics with formulation and processing approaches on bread quality. This will be achieved by establishing the effects of varieties and nitrogen applications in crop husbandry practices on...

Proposals for Regulation of Semiochemicals
Provedor de dados: 21
Autores: Speiser, Bernhard; Tamm, Lucius; Mattock, Susan.
Semiochemicals are substances that evoke behavioural or physiological responses. Pheromones modify the behaviour of other individuals of the same species, while allelochemicals act on individuals of different species. Pheromones are used in plant protection (i) to interfere with the mating behaviour of pests ('mating disruption'), (ii) to attract pests to insecticidal traps or baits ('attract and kill'), (iii) to trap pests ('mass trapping'), and (iv) to monitor pest populations. Semiochemicals present a particular case among active ingredients used in plant production products, as they are only substances not intended to kill the pest organism directly. The current regulatory system of pesticides is often seen as a major hurdle for the market introduction...

Autores: Karise, Reet; Muljar, Riin; Smagghe, Guy; Kaart, Tanel; Kuusik, Aare; Dreyersdorff, Gerit; Williams, Ingrid; Mänd, Marika.
Kaolin is an inert material with a broad range of applications, e.g. as an insecticide and as a filling substance in the formulation of biopesticides. Hence, bees that dispense biopesticides to the field in the context of entomovectoring are exposed to elevated risks because of sideeffects of those products. Here, we investigated with use of bumble bee workers of Bombus terrestris L. the lethal and sublethal effects of (i) pure kaolin, (ii) the biofungicide Prestop-Mix containing the parasitic fungus Gliocladium catenulatum and kaolin and (iii) the bioinsecticide BotaniGard containing the entomopathogenic fungus Beauveria bassiana and compared with wheat flour powder that we considered safe for bumble bees. As the most important result, treatment with...

A review of knowledge of the potential impacts of GMOs on organic agriculture
Provedor de dados: 21
Autores: Dale, Phillip; Clarke, Belinda; Fontes, Eliana; Martin, Wolfe; Pearce, Bruce; Welsh, James.
The organic movement believes that organic agriculture, by its nature, cannot involve the use of genetically modified organisms (GMOs).  This has been incorporated into EU regulations which state that there is no place in organic agriculture for GMOs.  The aim in this review is to consider the ways in which the use of GMOs in agriculture in the UK and internationally might impact on organic farming.  It does not address the controversy about the rights or wrongs of GMO’s per se.  The subjects covered are based on a set of questions raised at the beginning of the study.  The review is based primarily on evidence from peer-reviewed literature.    The report is based on a number of themes, as follows:  • Fate of DNA in soil  • Fate of DNA in livestock feed...

Nutrient use efficiency and arbuscular mycorrhizal root colonisation of winter wheat cultivars in different farming systems of the DOK long-term trial
Provedor de dados: 21
Autores: Hildermann, Isabell; Messmer, Monika; Dubois, David; Boller, Thomas; Wiemken, Andres; Mäder, Paul.
BACKGROUND: For organic farming, cultivars are required with high nutrient use efficiency under nutrient limited conditions. Arbuscular mycorrhizal fungi (AMF) are known to contribute to nutrient uptake under low input conditions. We compared nutrient use efficiency (NUE) of old and modern organically and conventionally bred cultivars in organic and conventional systems and assessed AMF-root colonisation (AMF-RC) in relation to nutrient concentrations.    RESULTS: Cultivars and systems had a statistically significant effect on nitrogen (N) and phosphorus (P) concentrations and NUE parameters, whereas no genotype × environment interactions appeared. In contrast to N and P uptake, the NUE parameters were higher under organic than under conventional...

Autores: Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Becker, Dorit; Wohanka, Walter.
Biological control of plant pathogens on strawberries may be improved by the simultaneous application of different biological control agents (BCAs). Therefore, the compatibility of various BCAs which had previously shown to be effective against powdery mildew (Podosphaera aphanis (Wallr.) U. Braun &amp; S. Takam) under laboratory conditions was examined in vitro. Inhibitory effects between fungal and bacterial BCAs were demonstrated in dual culture tests on two solid nutrient media. Leaf disc assays with single and multiple strain treatments demonstrated either unaffected or significantly improved control of P. aphanis for many multiple strain treatments, even if antagonistic interactions previously occurred in dual culture tests. Highest inhibition of...

Biologisch geteeld kleinfruit is enorm geliefd bij het grote publiek. Biotelers van houtig kleinfruit kampen echter met een aantal probleemplagen en -ziekten die ze zonder de krachtige chemische gewasbeschermingsmiddelen het hoofd moeten bieden. Daarom werd in 2013 in het kader van een CCBT-project in gezamenlijk overleg gezocht naar alternatieve oplossingen voor de bestrijding van deze plagen en ziekten. In de loop van dit project werden diverse overlegmomenten georganiseerd tussen telers, voorlichting en onderzoekers waarin de prioriteiten voor het onderzoek werden bepaald (dit uiteraard vooral door de biotelers zelf).

In the EC at the moment only cupper and sulphur products are allowed to regulate a multiplicity of diseases in different vegetable crops. On the other hand it is well know that both have also negative side effects on beneficial organisms and the soil. Since many years researches are looking for alternatives to reduce and substitute the use of the mentioned products.  Bicarbonates are substances which were pointes out for many years. They are present in nature and were used in the past in organic farming. Until now there was no registration for them in the EC as plant protection materials. There is a palpable possibility that it would change in future, what will open the possibility to apply for the introduction of potassium bicarbonate in annex 2B of the...

Bacillus polymyxa som växttillväxtbefrämjande och stresstoleransinducerande bakterier
Provedor de dados: 21
Forskare vid SLU har under det senaste året visat att markbakterien Bacillus polymyxa kan skydda växter mot växtpatogenen Erwinia samt förbättra växtens motståndskraft mot torka.                 I detta nya forskningsprojekt är syftet att undersöka på vilket sätt bakterien åstadkommer dessa effekter. Framför allt undersöks förändringar i växtens genuttryck. Markbakterier kommunicerar med varandra genom signalsubstanser, som också kan påverka växters tillväxt. Forskarna ska även undersöka dessa substanser för att kunna renframställa tillväxtbefrämjande ämnen. Projektet finansieras av spannmåls- och oljeväxtproducenter via Stiftelsen Lantbruksforskning.

Bioraps: Erfolg auch in Finnland
Provedor de dados: 21
Autores: Hokkanen, H.; Menzler-Hokkanen, I.; Daniel, C.
In Finnland gibt es schon länger einen nennenswerten Anbau von Bioraps als bei uns. Nach einigen Startschwierigkeiten sind Finnlands Biobäuerinnen und Biobauern bei einer Anbaufläche von gegen 3000 Hektaren angelangt. Lernen können wir aus der finnischen Erfahrung vor allem zu den Themen Rapsglanzkäfer und Untersaaten.  Seit etwa 10 Jahren werden in Finnland jährlich 2000–3000 Hektaren Biosommerraps angebaut. Einheimisches kalt gepresstes Biorapsöl ist nicht nur in Bioläden, sondern auch in den meisten Supermärkten erhältlich. Auch in Finnland übersteigt die Nachfrage immer noch das Angebot; die Ölpressen nehmen zurzeit nur noch Bioproduzenten neu unter Vertrag.

New Results from scab-experiments  (treatments on fallen leaves and summer-applications)

Autores: Pfeiffer, Barbara.
In the leaf-decompositon-trials to reduce the ascospore potential of Venturia inaequalis (2003/2004 and 2004/2005) different agents were tested with regard to direct effects on scab and to increasing the attractivity of the leaves for earthworms. TSB (lab medium with soya extracts) had a heavy direct effect on ascospore potential, but in this formulation it cannot be used in organic fruit-growing. Humofix and Bactofil B didn´t re-duce the potential as strongly as in the trial 2002/2003. A yeast extract and a combination of bean extract with powdered milk increased the attractivity for earthworms. In the trial 2004/2005 the reduction of the asco-spore potential was at best to 60 % of the control (powdered milk+Humofix), respecting the loss by earth-worms...

Sprays Used in Ecological Agriculture: Potential and Constraints for Use
Provedor de dados: 21
Autores: Znaor, Darko.
Due to the benefits of diversity, autonomous ecosystem management and careful farmers' stewardship, pest and disease control doesn't pose a profound problem in ecological agriculture practice. However, during the conversion period, and in ecological horticulture, particularly in fruit growing, this preventive control is often not sufficient enough, and additional control, mostly (curative) spraying is needed. This need for additional pest and disease control (spraying) in ecological horticulture, may be linked with our incomplete understanding of the role of those subsystems in the agro-ecosystem as a whole.     Currently, organic standards normally do specify permitted (environmental friendly, mainly natural substances), prohibited (synthetic pesticides),...

Pushing forward white lupin as a local source for protein and nitrogen in Central Europe
Provedor de dados: 21
Autores: Rosenfeld, Simon; Voegele, Ralf T.; Messmer, Monika; Finckh, Maria R.; Szuszkiewicz, Roderick; Oberhänsli, Thomas; Hohmann, Pierre.
White lupin (Lupinus albus L.) is a promising leguminous crop. Europe is fully dependent on protein and nitrogen fertilizer imports. This has tremendous negative effects both in Europe and the producing countries, such as loss of terrestrial biodiversity, pollution of freshwater, increase of greenhouse gases and soil acidification. Diverse crop-rotations with a substantial amount of pulses are a proven solution. The protein composition and yield potential of white lupin suggest that it could become the ‘Soy of the North’.  Currently, the seed-borne pathogen Colletotrichum lupini is substantially impeding the cultivation of white lupin in Central Europe. We developed a DNA-based diagnostic test to identify and quantify the fungal pathogen in plants and...

Einsatz mikrobiologischer Präparate zur Regulierung von Schadinsekten und Krankheiten an Erdbeeren
Provedor de dados: 21
Autores: Bisutti, Isabella Linda; Stephan, Dietrich.
Im organischen Erdbeeranbau sind bodenbürtige Krankheiten, z. B. Verticillium-Welke und Rhizomfäule, ein wachsendes Problem. Auch im konventionellen Anbau ist eine Bekämpfung der Verticillium-Welke nur bedingt möglich, da keine effizienten Pflanzenschutzmittel verfügbar sind. Aus diesem Grund sollte untersucht werden, ob Mikroorganismen zur Regulierung von bodenbürtigen Krankheiten an Erdbeeren verwendet werden können.  Hierfür wurden 98 Mikroorganismen, davon 68 Bakterien und 26 Pilze, in in vitro Tests gegen die Verticillium-Welke (V. albo-atrum, V. dahliae), die Rhizomfäule (Phytophthora cactorum) und die Rote Wurzelfäule getestet. In einem mehrstufigen Selektionsprozess wurden von den 98 Mikroorganismen 15 Mikroorganismen für weitere Laborversuche...

Disease control in organic cherry production with new products and early plastic cover of the trees
Provedor de dados: 21
Autores: Häseli, Andreas; Weibel,  Franco.
The effect of 3 new natural fungicides to control Monilia (Monilia laxa) of sweet cherry as well as the  effects of plastic cover during flowering period were tested in different trials on 4 organic farms in  Switzerland during three years. Under low to medium disease pressure Serenade (Bacillus subtilis),  Trilogy (Azadirachtin-free Neemoil) and lime sulphur reduced Monilia incidence by 30 to 60 %  relative to control. With high disease pressure, however, non of these products had a relevant  controlling effect.  Covering the trees during flowering period resulted in a &gt;90 % reduction of the 3 diseases Monilia  laxa, Clasterosporium carpophilum and Blumeriella japii.

Management of soil suppressiveness against soil-borne diseases
Provedor de dados: 21
Autores: Tamm, L.; Thürig, B.; Bongiorno, G.; Postma, J.; Fuchs, J. G.; Oberhänsli, T.
Soils suppressive to soil-borne diseases have attracted the attention of farmers and researchers for decades and many suppressive soils have been described. Microorganisms and soil microbial communities involved in suppressiveness have been studied intensively, but the underlying mechanisms are still not well understood. Suppressiveness to soil- as well as air-borne diseases has been shown to be highly site-specific. We will review how suppressiveness can be influenced by agricultural practices. Suppressiveness destroyed e.g. by steam sterilisation of soils could only be partially restored on the short-term by re-inoculation of soils, and the success of re-inoculation depended on the soil matrix as well as on the inoculum used. Long-term management (e.g....

Organic farmers urgently need cultivars resistant to Phytophthora infestans. Such cultivars also need to be adapted to other traits important for organic farming systems. One goal in the first five years of this ten-year, public-private partnership was to establish a program within the Dutch potato breeding system that includes farmer breeders working in close collaboration with six commercial breeding companies and two research institutes. To meet the goals we have involved 14 organic farmer breeders through setting up a yearly breeding course. A pre-breeding program is now running to introgress late blight resistance from wild relatives into cultivated material, and to make crossings with advances genitors to distribute seeds to farmer and commercial...

Protection biologique contre les nématodes à galles : test du champignon nématophage (Arthrobotrys conoïdes) : compte-rendu d'essai 2005
Provedor de dados: 21
Autores: Védie, Hélène; Geffroy, Thomas.
Les travaux menés par le GRAB depuis plusieurs années ont permis de tester l’intérêt des tourteaux végétaux, de neem et de ricin, et celui des engrais verts nématicides (tagetes, crotalaires…) dans la lutte contre les nématodes à galles (Meloidogyne spp). Les résultats de ces techniques s’avèrent aléatoires selon les sites, et sont insuffisants pour lutter efficacement contre ce ravageur du sol, notamment dans les sites très infestés.   L’avenir de la lutte contre les nématodes à galles en agriculture biologique passe très vraisemblablement par l’association de plusieurs techniques : raisonnement de la rotation, avec cultures de plantes non-hôtes ou résistantes (porte-greffes), désinfection (vapeur, solarisation), utilisation de tourteaux ou de la...

Biostrategie gegen Feuerbrand
Provedor de dados: 21
Autores: Schärer, Hansjakob; Tamm, Lucius; Häseli, Andreas; Weibel, Franco.
Der Bioobstbau ist gewappnet gegen den Feuerbrand – auch ohne das Antibiotikum-Präparat Streptomycin, das im Biolandbau nicht zugelassen ist. Für das laufende Jahr ist mit einem hohen Infektionsdruck zu rechnen, denn der Erreger ist nach dem hohen Befall im letzten Jahr fast überall zu finden. Wird eine breit angelegte Strategie sorgfältig umgesetzt, ist die Lage in den Griff zu kriegen.

Successful control of apple scab with hydrated lime
Provedor de dados: 21
Autores: Grimm-Wetzel, Peter; Schönherr, Jörg.
In an attempt to control scab, a 12-year-old apple orchard was treated with suspensions of 5 g/l hydrated  lime (Ca(OH)2) using overhead irrigation for 15 min. No other fungicides were used. In treatment A, irrigation  was started when infection according to Mills had taken place. In treatments B and C, treatment was delayed  by 6 h and 20 h, respectively. Irrigation was initiated when the scab warning system signaled even very low  infection risk, and a total of 62 treatments were applied. At harvest, the fruits of ‘Golden Delicious’ and  ‘Jonagold’ varieties of untreated controls were scabbed, while those of ‘Elstar’, ‘Fiesta’, and ‘Kent’ had no  visible scab symptoms. During both conventional and ULO storage for 7.5 months, all control fruits  developed...

Efficacy of Quassia extract on the apple sawfly Hoplocampa testudinea Klug
Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Maxin, P.; Rank, H.; Bathon, H.; Zebitz, C.P.W.
The efficacy of Quassia extract with a standardized content of Quassin was proved in various field trials in  different regions during three years. The amount of Quassin of 6 g/ha/m tree height will be recommended to  practice. It is not important to have a contact effect on the eggs. The larvae must feed on the product before  they enter the fruit. There is a very good efficacy on primaray infestation. Furthermore, there is even an efficacy  on secondary infestation. Thus, even if due to difficult conditions during application or not optimal termination  of the treatment the efficacy on the primary infestation is not entirely sufficient, the secondary infestation  will be controlled better.

Advantages and disadvantages of different break crops in organic grass/arable rotations (OF0143)
Provedor de dados: 21
Autores: Anon,.
This is the final report of Defra project OF0143.  Choice of break crops to grow in addition to cereals and the fertility building phase is crucial to the agronomic and economic success of organic arable rotations. There are four specific functions that a break crop may perform, namely: addition, conservation and cycling of nutrients; pest and/or disease control; weed control and improvement in soil physical characteristics. Individual break crops may perform one or several of these functions. A good break crop must also produce satisfactory yields, be of marketable quality and produce an economic return for the farmer.   This project analysed the overall suitability of new break crops by simultaneous assessment of key agronomic, economic and environmental...

Alcuni compost, addizionati al suolo o impiegati come componenti di substrati per colture in vaso, possono svolgere un’attività repressiva nei confronti dei patogeni terricoli. Nel biennio 2005-2006 sono stati saggiati, a Grugliasco (TO), in serre in ferro/vetro, compost provenienti da aziende di compostaggio presenti sul territorio piemontese al fine di valutarne la loro capacità repressiva. Dai risultati è emerso l’efficace contenimento nei confronti di F. oxysporum f.sp. basilici, da parte di compost prodotto a partire da rifiuti solidi urbani e fanghi, con una diminuzione fino al 50% di piante morte e un incremento fino al 25% di biomassa prodotta a fine ciclo rispetto a quanto rilevato impiegando un ammendante torboso scelto come riferimento.

Autores: Kienzle, Jutta.
Das pflanzliches Insektizid Pyrethrum ist für den ökologischen Obstbau ein unverzichtbarer Bestandteil der Pflanzenschutzstrategie. Die Breitbandwirkung und die entsprechenden Auswirkungen auf die Arthropodenfauna ist zwar zu berücksichtigen, kann aber im Freiland nicht mit Breitenwirksamkeit synthetischer Insektizide wie z.B. Pyrethroide oder Parathion verglichen werden. Der schnelle Abbau der Pyrethrine in Verbindung mit einer relativ geringen Mortalität sind gute Voraussetzungen für eine rasche Regeneration der Abundanz betroffener Arthropodengruppen.    Das neu zugelassene pflanzliche Insektizid NeemAzal-T/S stellt eine sehr wertvolle Bereicherung der Pflanzenschutzstrategie im ökologischen Obstbau dar.

Organic Food and Health: A new project to study the effects of plant cultivation methods (organic and conventional) on nutritional value, health and reproduction in an animal experiment
Provedor de dados: 21
Autores: Brandt, Kirsten; Nygaard Larsen, Hanne; Andersen, Jens-Otto; Mølgaard, Jens-Peter; Lauridsen, Charlotte; Jørgensen, Henry; Gundersen, Vagn; Larsen, Erik; Badsberg, Jens Henrik; Thorup-Kristensen, Kristian.
Many consumers believe that food from plants grown under certain conditions, such as organic agriculture, will benefit health more than conventional food. This cannot be determined simply by analysing the material, since our understanding of the connections between food components and health is still to imprecise for such a purpose. Rather than waiting until basic research provides the knowledge needed for this approach, in the spring of 2001 we have initiated a project to study physiological effects of plant quality directly, in an animal experiment.     The following cultivation treatments are used to grow plants that are typical ingredients for a human diet (potato, mature peas, kale, spring wheat, oilseed rape, carrots and apples):    1.

Entomopathogenic fungi as a new strategy to control the European cherry fruit fly Rhagoletis cerasi Loew (Diptera: Tephritidae)
Provedor de dados: 21
Autores: Daniel, Claudia.
The European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), is a highly destructive pest of sweet cherries in Europe. Up to 100% of the fruit can be infested. Methods for controlling this pest are limited in organic agriculture as well as in integrated production, as the insecticide currently used (Dimethoate) is being challenged due to problems of ecotoxicity and residues. Alternative methods for cherry fruit fly management are therefore needed. The aim of this thesis was to develop a new control strategy for R. cerasi using entomopathogenic fungi.  In a first step, the effects of six fungus isolates on the mortality of different life stages of R. cerasi were assessed in a series of laboratory experiments. All fungus isolates caused...

L'enherbement permanent comme alternative au travail mécanique sous les oliviers
Provedor de dados: 21
Autores: Warlop, Francois; Andrieu, Camille; Sallaberry, Camille; Filippi, Olivier; Lemoine, Hélène.
Le travail mécanique au pied de l'arbre, pour contrôler l'enherbement, demande trop d'attention et d'énergie pour un résultat souvent imparfait.  Les agriculteurs sont demandeurs d'alternatives fiables aux herbicides et au travail mécanique. Une flore adaptée au pied des arbres représente une solution séduisante d'autant plus qu'elle peut jouer un rôle agroécologique utile. L'expérimentation a permis de suivre le développement d'espèces couvre-sols, choisies en fonction de résultats obtenus sur d'autres vergers, et de leurs propriétés attendues (faible concurrence, port ras, étalement rapide). Certaines espèces ont des comportements adaptés aux conditions de culture de l'olivier.

Anthracnose bei Rotklee: Ansätze zur Züchtung resistenter  Sorten
Provedor de dados: 21
Autores: Jacob, Irene; Hartmann, Stephan.
Der Rotkleeanbau in Deutschland könnte künftig durch eine Pilzkrankheit, der Anthracnose, erschwert werden. Um den Anbau weiterhin zu sichern, wurden die in Deutschland zugelassenen Rotkleesorten hinsichtlich ihrer Resistenz gegen die Krankheit in einer Prüfung im Gewächshaus evaluiert. Weiterhin wurde untersucht, ob man mit dem Verfahren der rekurrenten Selektion eine Anhebung des Resistenzniveaus bestehender Populationen erreichen kann. Zudem wurden molekulare Markeranalysen durchgeführt, die die Basis künftiger Züchtung durch markergestützte Selektion (MAS) bilden können.

Molecular diagnostic methods can prevent unnecessary rejection of organic seed lots
Provedor de dados: 21
Autores: Justesen, A.F.; Pinnschmidt, H.O.; Hansen, H.J.
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P. graminea (barley leaf stripe), which causes rejection of seed lots. A real-time PCR method for detection and quantification of P. graminea has been developed.

Fertile soils are highly important for arable farming. To maintain soil fertility, crop rotation including legumes is applied, particularly in stockless farms. Yet, many commercial farms report yield reductions for legumes. The aim of the present study was to evaluate whether the causes for the observed soil fatigue can be narrowed down by a bioassay (modified differential diagnosis according to Bouhot) and whether this bioassay could be a useful tool to predict the suitability of a field to grow legumes.

Entwicklung von Anbaustrategien zur Sicherung und Ausweitung des heimischen Anbaus von Bio-Einlegegurken
Provedor de dados: 21
Autores: Rupp, Jochen.
Der Bedarf nach Einlegegurken aus ökologischer Erzeugung ist in den letzten Jahren stetig gewachsen. Er kann nicht mit inländischer Ware gedeckt werden. Dies ist auf das hohe Anbaurisiko des Erzeugers bedingt durch Befall mit Pseudoperonospora cubensis zurückzuführen.  Nach Erstbefall dauert es nur 3 Wochen bis die Kultur abgebrochen werden muß. Innerhalb des Projektes 06OE150 wurden folgende Lösungswege verfolgt:  - Verlängerung der potentiellen Kultur- / Erntezeit durch Verfrühung bzw. Pflanzung  - Verwendung resistenter Sorten  - Einsatz neuer Pflanzenstärkungsmittel  Über einen Zeitraum von 3 Jahren liefen Versuche in Oberbayern, Franken und Brandenburg.  Die Ergebnisse zu den drei Lösungsansätzen fielen allesamt ernüchternd aus. Beim Vergleich des...

Autores: Burmeister, Johannes; Walter, Roswitha.
Short rotation alley cropping can affect biodiversity and ecosystem services. Thus the epigeic fauna was investigated in different distances from a strip with short rotation poplar cultivation at two sites in Bavaria. An increase of carabid beetle diversity on field-scale was noted due to the appearance of adapted carabid species inside the strip, however with no distinct correlation between distance from poplar strip and carabid species diversity. Slug activity density decreased with increasing distance.

First experiences in the application of biopreparations against the cherry fruit fly in Southern Russia in 2007
Provedor de dados: 21
Autores: Vasilyeva, L. A.; Hummel, E.
On the Russian market there are no currently registered biological preparations for the  control of Rhagoletis cerasi (cherry fruit fly, CFF), and therefore the effects of natural  products against this pest were studied. In laboratory, semi-field and field experiments a  range of botanicals (NeemAzal-T/S and Quassia-MD) were tested alone and in  combination with comparison product Phytoverm and chemical standard insecticides for  their effectiveness against R. cerasi in commercial orchards. These products showed a  high biological effectiveness against R. cerasi comparable with chemical insecticides.

Dispersal of Rhagoletis cerasi in commercial cherry orchards: Efficacy of soil covering nets for cherry fruit fly control
Provedor de dados: 21
Autores: Daniel, Claudia; Baker, Brian.
Demand for organic cherries offers producers a premium price to improve their commercial viability. Organic standards require that producers find alternatives to pesticides. Soil treatments to control the European cherry fruit fly Rhagoletis cerasi (L.)(Diptera: Tephrididae) appear to be an attractive option. However, soil treatments can only be effective if the migration of flies is low, because mature flies may migrate from near-by trees for oviposition. To examine the general potential of soil treatments and to understand the dispersal and flight behaviour of R. cerasi within orchards, experiments using netting to cover the soil were conducted in two orchards with different pest pressure during two years. The netting reduced flight activity by 77% and...

The Colorado Potato Beetle is one of the most important pests of potatoes. The effect of various plant protection products based on neem (NeemAzal-T/S), pyrethrum/rape oil (Spruzit Neu) and Bacillus thuringiensis - B.t.t. (Novodor FC) against this pest has been compared in a field experiment from 2004 until 2006. The combined application of neem and B.t.t.-product have reduced the number of Colorado Potato Beetle larvae as well as the losses of plant material by feed of the beetle larvae significantly. In three years of field experiments the application of pyrethrum/rape oil has shown no significant effect to reduce the number of Colorado Potato Beetles.

Effects of different row distances and seed densities on yield and quality of blue lupins (L. angustifolius) in organic farming
Provedor de dados: 21
Autores: Böhm, Herwart; Aulrich, Karen.
Blue lupins have become more important in animal feeding due to increasing organic animal husbandry. The high protein content of blue lupins shows the best protein quality of the home-grown grain legumes combined with low starch content. The feed quality of blue lupins can be analysed very quickly and cost-effi ciently with NIRS. Weed infestation in pure stands of blue lupin is often a problem. Mixed cropping systems are a good alternative for weed suppression, but the yield percentage of blue lupins in mixed cultivation is low.  Weed infestation can be reduced by hoeing. For this, blue lupins were cultivated in wider row distances (25.0 cm, 37.5 cm) with the possibility of hoeing, and compared with the cultivation to 12.5 cm row distance (only harrowing)....

Im Jahr 2000 konnte überall eine sehr starke Berostung an 'Elstar', 'Jonagold' und anderen Apfelsorten festgestellt werden. Die starke Qualitätsminderung durch Berostung trat jedoch nicht nur in der ökologischern Apfelproduktion sondern auch bei integriert wirtschaftenden Obstbaubetrieben auf. Bei der Ursachensuche wurde häufig Schwefelkalk im Zusammenhang mit Berostung erwähnt. Die Erfahrungen mit Schwefelkalk, die in vielen Versuchen an der Staatlichen lehr- und Versuchsanstalt Ahrweiler gewonnen wurden, deuteten jedoch nicht auf ein starkes Berostungspotential des Schwefelkalkes hin. Jedoch ist der pH-Wert von Schwefelkalk sehr hoch und liegt bei einem Wert von über 12. Alkalische Spritzbrüher werden im Allgemeinen als berostungsfördernd betrachtet. Um...

Biological control of Frankliniella occidentalis on table grapevine using predation and plant association
Provedor de dados: 21
Autores: EL KHOURY HANNA, Youssef.
Since 1989-90, Frankliniella occidentalis (Pergande) has been classified as the most harmful insect for table grapes after Lobesia botrana ( Den et Schiff.)Cultivar “Italia”, the most economically-relevant table grapes variety in Apulia, is  susceptible to Frankliniella occidentalis  which induces typical halo spots symptoms. Many conventional and IPM control methods have been developed to limit the attacks of this pest. In contrast little has been made for the biological control in the vineyard. This present work aims on one hand to verify the damage of Frankliniella in the presence of attractive blue flowers of Phacelia tanacetifolia, and on the other to evaluate the predation efficiency of the predator Orius. In that context, Phacelia tanacetifolia,...

In a pilot field study conducted in an apple orchard in Hardanger (Western Norway) in two  succesive years both Beauveria bassiana and Metarhizium anisopliae were applied to  apple trees just after hatching of mirid nymphs in spring. Both predatory, omnivorous and  principally plant-pathogenic species of mirids were collected, and all groups of species  were infected by B. bassiana or M. ansiopliae in treated plots. B. bassiana and M.  anisopliae were also found on some individuals in non treated control plots the second  year. M. anisopliae was more predominant in 2006, B. bassiana in 2007. Mirids were also  observed for natural occurrence of parasitoids, and parasitoids were found both years.

1. Feldversuche  Die Winterweizensorten Arina und Capo wurden im Versuchsjahr 2002/2003 auf insgesamt 12 Standorten im Ökologischen Anbau als Reinbestände und als Sortenmischung angebaut. Das Versuchsjahr war extrem trocken, weshalb kein relevanter Krankheitsbefall zu verzeichnen war. Die Erträge variierten je nach Standort von 26 bis 53 dt/ha wobei Capo deutlich ertragsstärker war als Arina. Die Mischung brachte im Schnitt 3% mehr Ertrag als erwartet und war im Ertrag deutlich stabiler. Dies war auf die stärkere Konkurrenzkraft der Sorte Capo an fast allen Standorten zurückzuführen.  Arina übertraf Capo signifikant im Rohprotein (RP) (12.9 versus 12.2%) und Feuchtklebergehalt (FK) (29.8 versus 25.3%), was auch im Backvolumen reflektiert wurde. Während bei...

Autumn applications of sulphur – a new approach to control the pear leaf blister mite Eriophyes pyri.  Abstract: The pear leaf blister mite can cause severe damage to pear leaves and young fruits in some regions. Due to hidden living inside leaf blisters, the mites are largely protected against the impact of plant protecting agents. Until now, treatments with mineral oil or rape oil in early spring, during the time when the mites leave their hibernation sites under the bud scales to invade the young leaves and blossoms, are the only possibility to control these mites in Swiss organic fruit growing. The aim of this study was to examine the effects of sulphur, mineral oil and Surround®WP applied after harvest during the time, when the mites leave their...

A survey of natural parasitism of mirid bugs by parasitoids on apples and pears in Norway
Provedor de dados: 21
Autores: Jaastad, G.; Trandem, N.; Hovland, B.; Djønne, R. T.
Mirid bugs are important pests in both integrated and organic fruit production. In a survey  in 2006 the proportion of mirids parasitized by parasitoids was investigated in 18  Norwegian orchards. More than 50 beating samples were collected from apple and pear  orchards under integrated and organic management in different areas of Norway. About  30% of nymphs of the most abundant mirid bug species, Lygocoris pabulinus, Ortholylus  marginalis and Psallus ambiguus, were parasitized. Important factors for enhancing  biological control in organic fruit production are discussed.

Autores: Jones, H; Clarke, S M; Haigh, Z; Hinchsliffe, K; Wolfe, M S; Thomas, J; Gibbon, D; Harris, F; Lyon, F.
The performance of UK winter wheat varieties was tested under organic conditions involving farmer participation. Three breadmaking varieties (Hereward, Solstice and Xi19) and their mixture (1:1:1) were grown at 19 UK farms in 2003/04 and 2004/05. The variability of productivity on organic farms was illustrated with more variation among farm sites than among varieties. Seed health was generally high over all sites. Although the trials were successful, more time was needed at project initiation to improve farmer involvement. Some farmers expected more researcher visits, and were reticent about assessing the trials themselves. In contrast, some participants valued the variety performance data on their farms particularly when related to that of other growers....

Organic Centre Wales Technical Note 6: Biology and management of leatherjackets
Provedor de dados: 21
Autores: Anon,.
Leatherjackets are the larvae of crane flies (Tipula spp.) which are better known as daddy longlegs. The largest populations are found in grassland and populations in infested fields can reach 0.6 million leatherjackets/ha. The threshold population for field crops is 0.25 million/ha. Crops of brassicas, courgettes and roots following grass may suffer most damage. Damage is usually seen in spring with young plants and seedlings the worst affected.  This technical note discusses natural enemies of leatherjackets, nature of damage, life history and control measures, and a list of sources of further information.

In this study, the impact of grazing in comparison to cutting on yield and forage feeding value at permanent grassland swards was investigated. A six-year trial (2007-  2012) was established at the Institute of Organic Farming of AREC Raumberg- Gumpenstein to test four types of permanent grassland uses (1: annual change between cutting and grazing; 2: four times cutting year-1; 3: cut of the first growth following grazing; 4: grazing). There were found no significant differences in the DM yield between the four variants. The significant highest crude protein yield (over 1,843 kg ha-1) was found in the grazing system. Energy concentration of grazed swards reached 7 MJ NEL kg-1 DM during spring and decreased to 6.2 MJ NEL kg-1 DM  during summer. Crude...

Nutrition ecology of Ascogaster quadridentata (Hymenoptera,  Braconidae) and its host in apple orchards
Provedor de dados: 21
Autores: Herz, Annette; Drexler, Nils; Matray, Silvia; Veekmann, Oliver.
The codling moth, Cydia pomonellaL. (Lepidoptera, Tortricidae) is the key pest in apple growing worldwide. Its increasing resistance against various insecticides, including granulosevirus based plant products, initiate the search for supporting tools for natural control, e.g. the activity of parasitoids. The Chelonine species Ascogaster quadridentata, an egg-larval parasitoid, does not host-feed, but requires sustainable access to sugar resources for nutrition. In the framework of the European CoreOrganic Plus project EcoOrchard (http://coreorganicplus.org/researchprojects/ ecoorchard/)weestablished flowering strips in the rows between trees with the aim to support natural enemies. In adjacent laboratory tests we explored which kind of flowering plants and...

Monitoring of click beetles (Agriotes lineatus and A. obscurus) in organically managed farms in Northern Germany
Provedor de dados: 21
Autores: Böhm, Dr. Herwart; Koppe, Wiebke; Dreyer, Wilfried.
Wireworms, the larvae of Agriotes spp., are an increasing problem on many organically managed farms with potato or vegetable production. The damage caused by wireworms is economically significant. With the use of pheromone traps it is possible to get more information about the habitat requirements of click beetles. In 2005 and 2006 click beetles were monitored at different locations in northern Germany. Because of the warmer springtime in 2005, the first peak of click beetles was about two weeks earlier than in 2006. The second peak was found one month later. The presented data show the highest occurrence of click beetles in ryegrass-clover mixtures in both years. The catches in cereals were much lower than in ryegrass-clover. The reasons for the...

Ensilert bygg ble sammenlignet med tørket bygg som eneste kraftfôr til melkekyr i økologisk landbruk. Melkeproduksjonen har vært moderat i gruppen med 40% kraftfôr og lav i gruppen med 10% kraftfôr. Både tørking og ensilering konserverte bygget godt, med antydning til mugg på toppen av sekker med det ensilerte. Begge fôrslag hadde omtrent samme virkning på fôropptak og produksjon. Det har vist seg at bygg alene er for lite smakelig når det gis større mengder. Proteininnholdet i bygg var for lavt når det ble gitt som eneste kraftfôr til et surfôr med lavt proteininnhold.

Management of strawberry blossom weevil and European tarnished plant bug in organic strawberry and raspberry using semiochemical traps
Provedor de dados: 21
In the absence of effective control measures, the strawberry blossom weevil (Anthonomus rubi), the European tarnished plant bug (Lygus rugulipennis) and the raspberry beetle (Byturus tomentosus) cause large (10 - &gt;80%) losses in yield and quality in organically grown strawberry (A. rubi and L .rugulipennis) and raspberry (A. rubi and B. tomentosus). In this project the natural semiochemical mechanisms of sexual attraction and host plant finding of these key pests will be exploited to develop effective semiochemical traps for their management through mass trapping. Attractive lures will be combined into a single multitrap for economic management of these pests simultaneously in each crop. This will be one of the first approaches to pest management of...

Development of a strategy for fire blight control in organic fruit growing
Provedor de dados: 21
Autores: Kunz, Stefan; Haug, Philipp.
Effective control strategies are needed in organic fruit growing to prevent blossom infections by the fire blight pathogen Erwinia amylovora. There are many potential control agents under discussion. 18 preparations have been tested for their efficiency against Erwinia amylovora.  Twelve of them were highly effective against E. amylovora in vitro.  Nevertheless only five of them led to a symptom reduction of  more than 50% on de-tached apple blossoms. These results and data on field performance from the literature indicate that Blos-som-Protect is the most effective preparation to prevent blossom infections by fire blight. Therefore further experiments have been performed to develop a strategy for the use of  Blossom-Protect in organic fruit grow-ing. The...

Management-induced Soil Structure Degradation: Organic Matter Depletion and Tillage
Provedor de dados: 21
Autores: Kay, B.D.; Munkholm, L.J.
Soil structure is an important element of soil quality since changes in structural characteristics can cause changes in the ability of soil to fulfil different functions and services. Emphasis in this chapter is placed on the role of soil structure in biological productivity of agroecosystems. Combinations of management practices in which the extent of the degradation of soil structure caused by one practice is balanced or exceeded by the extent of regeneration by other practices will help sustain the productivity of agroecosystems. Tillage and practices that change the organic matter (OM) content of soil are foremost among the many practices that influence soil structure. The links between management, OM content and soil structure and between tillage and...

Nützlingsförderung in einjährigen Kulturen bedeutet, Leistungen der räuberisch (z.B. Spinnen, Marienkäfer) und parasitisch (z.B. Schlupfwespen) lebenden Nützlinge signifikant zu erhöhen. Durch naturnahe Flächen wie lang blühende Wildkrautstreifen, perennierende Säume, Hecken und artenreiche Wiesen werden die Nahrungsgrundlagen und Überwinterungschancen für viele Nützlinge und andere Tierarten entscheidend verbessert. Um eine hohe Schädlingsregulation zu erreichen, ist es meist nicht ausreichend allein die generelle biologische Vielfalt zu fördern.

Biofumigation zur Bekämpfung von Verticillium dahliae
Provedor de dados: 21
Autores: Michel, Dr Vincent.
Cruciferous plants with high contents of glucosinolates can be used to control soilborne  diseases. During the degradation of such plants, the glucosinolates are  transformed into isothio- and thiocyanates. These molecules are volatile and toxic,  therefore, this method is called biofumigation. In this context, the efficacy of two brown  mustard (Brassica juncea) and one canola (Brassica napus) cultivars to reduce the  number of Verticillium dahliae microsclerotia was tested in pot trials. Verticillium  dahliae is the causal agent of verticillium wilt of a large number of important crops.  Microsclerotia are the surviving structures of V. dahliae in the soil. A strong decrease  of the number of microsclerotia was observed using the high...

Autores: Schmid, Andi; Daniel, Claudia; Weibel, Franco.
Damage of leaf spot, caused by Mycosphaerella fragariae and gray mold also called Botrytis fruit rot, caused by Botrytis cinerea, average fruit weight and yield were evaluated with regard to cultural methods over two years. Leaf spot damage decreased significantly by around 90 % due to leaf sanitation (removal of dead and leaf spot infected leaves in early spring) and by 50 % due to plantation in a one-row-system instead of a two-row-system. When all leaves including the healthy green ones were removed in early spring average fruit weight decreased significantly by 10 %. Fruit sanitation - the third treatment – did not influence any of the measured parameters.   Neither leaf sanitation nor fruit sanitation (removal of damaged fruits during harvest) reduced...

In 1994 und 1995 durchgeführten Labor- und Freilandversuchen konnten wir zeigen, dass die Werren (Maulwurfsgrille; Gryllotalpa gryllotalpa L.) mit einer Nematodenart (Steinernema capocapsae) biologisch reguliert werden können. Bei einem hohen Werrenbesatz reduzierte eine 60 cm breite Streifenbehandlung innerhalb den Pflanzreihen den Ausfall an Tomatenpflanzen im Folientunnel um 84 Prozent.     Die Nematodenart S. carpocapsae wurde in der Praxis bisher gegen Erdraupen und Larven des Dickmaulrüsslers eingesetzt. Sie gilt als relativ spezifisch und sucht aktiv die Werre auf und dringt durch ihre Körperöffnungen ein. Dabei gibt sie Bakterien aus ihrem Verdauungstrakt ab, was nach starker Vermehrung innerhalb weniger Tage den Tod der Werre verursacht. Die...

Sulfur and baking-quality of breadmaking wheat
Provedor de dados: 21
Autores: Hagel, Ingo.
It is well known in biological science that all factors applied to living organisms (light, water, warmth, fertilizers etc.) show an optimum, when their input is increased. Healthy organisms and sus-tainable systems are, on the long run, only achieved when care is taken not to destroy this equilibrium of factors producing an optimum. With regard to the baking quality of wheat breeders and cereal scientists obviously failed to achieve this aim by breeding their cultivars on the background of ample S depositions in the ecosystems. They (involuntarily) selected plants showing definite characteristics of S deficiency (higher proportions of HMW-glutenin, stronger gluten and dough) even under conditions of ample S supply. I suppose they also selected plants with...

Efficacy of Armicarb (potassium bicarbonate) against scab and sooty blotch on apples
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Schärer, Hansjakob; Refardt, Matthias.
A novel formulation of potassium bicarbonate (Armicarb) was evaluated in 2004 and 2005 as agent against apple scab (3 field trials) and sooty blotch (2 field trials). Armicarb controlled scab equally well as the reference treatments sulphur and copper. Armicarb showed also excellent activity against sooty blotch. However, potential side-effects such as lenticell spot development need further investigation. At present, potassium bicarbonate is considered by the Swiss registration authorities as non-toxic to humans and in consequence, no residue levels have been specified.  Armicarb has very interesting properties as a plant protection agent and its composition and risk profile are expected to fulfil the IFOAM standards for acceptance of novel plant...

Physikalische Barrieren (Insektenzäune) zur Regulierung von Gemüseschädlingen
Provedor de dados: 21
Regulierung von Gemüseschädlingen mit Hilfe von vertikalen Netzen (Insektenzäunen)  Viele wichtige Gemüseschädlinge, wie zum Beispiel die Möhrenfliege, die Kleine Kohlfliege und die Kohldrehherzgallmücke, sind ausgesprochene Tiefflieger, das heisst sie bewegen sich in oder nur knapp über der Vegetation fort. Stellt man ihnen ein Hindernis in den Weg, versuchen sie nach oben auszuweichen. Hat dieses Hindernis auch noch einen Überhang, so bleiben die Schädlinge dort gefangen, weil sie immer nur nach oben und hin zum Licht ausweichen.  Ausgehend von dieser in Kanada gemachten Beobachtung, wurden am FiBL Versuche mit vertikal stehenden Netzen, so genannten Insektenzäunen, gemacht, um Schädlinge am Einflug in die Kultur zu hindern. Nach den guten Ergebnissen...

Versuche zur Reduzierung kupferhaltiger Pflanzenschutzmittel   im ökologischen Hopfenbau
Provedor de dados: 21
Autores: Schwarz, Johannes; Weihrauch, Florian.
In den Jahren 2010 und 2011 wurden im Rahmen eines noch laufenden Forschungsprojektes Versuche zur Reduzierung der Kupferaufwandmenge bei der Bekämpfung des Falschen Mehltaus im ökologischen Hopfenbau gesucht. Getestet wurden Kupferhydroxide und Kupferoxychlorid mit niedrigen Aufwandmengen (2 und 3 kg/ha) an Reinkupfer sowie in Kombination mit den drei Pflanzenstärkungsmitteln 'Herbagreen', 'Biplantol' und dem phosphonathaltigen 'Frutogard'. Die ersten Ergebnisse zeigen, dass mit modernen Kupferhydroxiden eine erfolgreiche Bekämpfung des Falschen Mehltaus auch mit einem reduzierten Aufwand von 3 kg/ha Kupfer möglich sein kann. In Kombination mit den geprüften Pflanzenstärkungsmitteln wurde sogar durchwegs eine Wirkungsverbesserung erzielt. Die besten...

Soil nitrogen in an organic apple orchard
Provedor de dados: 21
Autores: GIRARD, T.; SIMON, S.; CORROYER, N.; FAURIEL, J.; BUSSI, C.
Introduction  The lack of vigour of an organic apple orchard (Smoothee cultivar) planted in 1994 pointed out the management of tree nitrogen supply in this orchard. Serious damages due to Dysaphis plantaginea, the rosy aphid, were also noted on trees. As tree vigour and therefore aphid population levels are related to nitrogen nutrition, the monitoring of soil nitrogen availability was necessary to analyse the causes of these problems. Besides, the aim was to optimise the orchard organic nitrogen fertilisation.    Materials and methods  From 1994 to 1998, the fertilisation management mainly consisted in compost supply (10 t.ha-1). From 1999 to 2001, autumn compost supply was reduced to 5 t.ha-1, complemented with organic quickly mineralised fertilisers in...

Aedmaasikas on maailmas üks enam kasvatatavaid marjakultuure. Kuigi enamik aedmaasika Fragaria x ananassa sortidest on isetolmlemisvõimelised, aitab risttolmlemine kaasa suuremate ja kõrgema kvaliteediga viljade moodustumisele (Klatt jt., 2014). Puudulikult tolmeldatud õitest arenenud viljad on sageli ebakorrapärase kujuga ja väiksemad. Lisaks on hästi tolmeldatud viljad ka paremini värvunud, tugevama  viljalihaga ning säilivad korjamisjärgselt kauem (Klatt jt., 2014). Aedmaasika põhiliseks kahjustajaks on hahkhallitus, Botrytis cinerea (Legard jt., 2000), mille tõrjumisel on sünteetiliste preparaatide kõrval osutunud efektiivseks ka mullaseen Gliocladium catenulatum.

Sustainable apple breedings needs sustainable marketing and management
Provedor de dados: 21
Autores: Weber, M.
Apple breeding programmes are currently in the middle of transition in terms of  ownership and management. Until now most of them were funded by the public.  Breeding took place by traditional methods since decades in a very sustainable way  to develop better apple varieties. Today, increasing loss of national boundaries and  globalisation, less interest by national bodies and institutions and rising cost levels  for high tech breeding methods entire programmes are nowadays urged to look for  new sustainable co- or self-financing business models in order to continue their  work. The paper explains through financial calculations how risk can be split by all  partners and how the supply chain can be developed further into a value chain by  using a collective...

Introduction  The vast majority of apple production in Europe takes place in intensive orchards, this implies the need for intensive capital investment for support structures which then have to be used for a number of generations of trees. Consequently new orchards have to be replanted in the same place as previous plots. This causes soil sickness or yield decline of which “replant disease” is the main biological component. Resulting yield losses are difficult to assess; a recent study in South Tyrol, where 12% of total EU apple is produced, showed that growth reduction can vary from 20 to 60% in replanted orchard compared to fallow control. Severity of this etiology is mediated by plant vigour, physiological state of plants and abiotic factors. Therefore,...

Combined production of broilers and fruits
Provedor de dados: 21
Autores: Lindhard Pedersen, H.; Olsen, A.; Pedersen, B.; Korsgaard, M.; Horsted, K.
Combined production of broilers and fruit trees is a subject often discussed in organic fruit  production in Denmark. Very little research has been carried out on this type of production  system. In organic production in Denmark, nearly no pesticides are allowed, so the need  for alternative pest control is large. Apple sawfly (Hoplocampa testudinea) and pear midge  (Contarinia pyrivora) cause big crop losses in apples and pears respectively, in unsprayed  organic fruit production. Both insects infest fruitlets and cause these to drop prematurely  after which the pests pupate in the topsoil. In the present experiment a research orchard  with the varieties ‘Discovery’ and ‘Conference’ were used as outdoor area for broilers to  minimise the population of...

Autores: Hagner, Marleena; Pasanen, Tiina; Lindqvist, Bengt; Lindqvist, Isa; Tiilikkala, Kari; Penttinen, Olli-Pekka; Setälä, Heikki.
The use of birch tar oil (BTO) is a new innovation in plant and animal protection working against various weeds, harmful insects and rodents. Due to its novelty as a biocide/repellent/plant protection product, no comprehensive information on the effects of BTO on non-target soil organisms is available. In this study we examined the impact of BTO on non-target soil organisms (enchytraeids, nematodes and soil microbes) and plants using laboratory toxicity tests and field experiments. In addition, we determined the LC50 value of BTO to the earthworm Aporrectodea caliginosa and the EC50 value of BTO to the offspring production of the collembolan Folsomia candida. The effects of BTO on soil fauna were mostly insignificant. BTO seemed to be detrimental to the...

The European cherry fruit fly (Rhagoletis cerasi) is the only pest insect which makes a  insecticide treatment of cherry fruit necessary. With regard of residue free cherries a  biocontrol method for R. cerasi by soil applications seems attractive. However, soil  treatments can only be effective if the migration of flies is low. In order to examine the  potential of soil treatments and to understand the dispersal behaviour of R. cerasi in  orchards, experiments using nettings to cover the soil were conducted. The  experiments were arranged in commercial, organically managed orchards. The  nettings reduced fruit infestation by 90%. In addition, it was shown that the flies move  only very short distances (less than 5 m) within orchards. Thus, soil treatments...

Alternativen zur Anwendung von Kupfer als Pflanzenschutzmittel [Alternatives for copper application as plant protection products]
Provedor de dados: 21
Autores: Schleuß, Uwe.
Zusammenfassend lässt sich nach dem 7. Fachgespräch "Pflanzenschutz im ökologischen Landbau" in Berlin resümieren, dass zur Zeit auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau noch nicht verzichtet werden kann. Um die Umweltauswirkungen so gering wie möglich zu halten, ist eine Minimierung der Aufwandmenge anzustreben. Dabei muss natürlich die fungizide Wirkung erhalten bleiben. Ein Durchbruch beim Ersatz von kupferhaltigen Pflanzenschutzmitteln ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Daher ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen, z. B. Anbau resistente Sorten.

Organic Methods for Control of Root Rot in Pea and Spinach in Northeastern U.S.
Provedor de dados: 21
Autores: Schrum, H. W.; Kotcon, J.; Verlinden, S.
The root rot disease complex is a limiting factor in organic production of cool season crops. This study aimed to increase seedling stands of peas and spinach by altering the seed environment such that the growing conditions of the seeds were favored over those of the pathogens. We compared treatments of raised (ridged) seed beds, dairy and vermicompost troughs, transplanting, and a biocontrol soil drench. Of the methods tested, transplanting provided the most reliable and best crop stands for both seasons (p=0.05) Since this method relies on the biological resistance the plants develop naturally with age, this method could prove applicable across many climates and other crops which are threatened by root rot.

Results from two years of sanitation measures to reduce apple scab in organic orchards
Provedor de dados: 21
Autores: Kelderer, Markus; Lardschneider, Ewald; Marschall, Klaus.
Scab is still a big challenge for those apple orchards which are managed organically.  Inoculum survives during winter in leaf litter, and sporulates in spring when  vegetation starts. Different surveys in other regions showed that it is possible to  reduce the presence of scab in apple orchards by removing the leave litter from the  orchards. Different trials were carried out to understand if sanitation measures would  also be of practical interest in organic orchards in South Tyrol. The results varied. In  some trials, scab was reduced on the leaves up to 60%, in others no differences  were observed. It is therefore not clear if the results justify the expense of cost and  time for such measures.

Regulierung der Kraut- und Knollenfäule im ökologischen Landbau durch Verwendung resistenter Sorten und Unterblattspritzungen mit reduzierter Kupfer-Aufwandmenge
Provedor de dados: 21
Autores: Biologische Bundesanstalt für Land- und Forstwirtschaft, Institut für Pflanzenschutz in Ackerbau und Grünland.
Auf der Versuchsfläche Ahlum der Biologischen Bundesanstalt für Land- und Forstwirtschaft Braunschweig wurde in einem zweijährigen Feldversuch die Möglichkeit der Befallsreduktion von Phytophthora infestans durch den Anbau von Kartoffelsorten mit unterschiedlicher Anfälligkeit sowie durch differenzierte Kupferanwendungen mit Unterblattspritztechnik im ökologischen Kartoffelanbau untersucht.   Dabei zeigten sich im Befallsjahr 2002 in den Kontrollvarianten zwischen den Sorten Secura, Grata und Bettina Anfälligkeitsunterschiede, die in Übereinstimmung mit den Angaben der Beschreibenden Sortenliste stehen. Die unterschiedliche Anfälligkeit der Sorten spiegelte sich nicht in den Ertragsleistungen der unbehandelten Varianten wider. In beiden Versuchsjahren...

Erarbeitung einer Strategie zur Reduzierung des Kupfereinsatzes bei der Apfelschorfbekämpfung im ökologischen Obstbau
Provedor de dados: 21
Der Apfelschorf (Venturia inaequalis) stellt in den Obstbaubetrieben, die nach ökologischen Richtlinien wirtschaften, ein großes Problem dar. Daher ist eine konsequente Schorfbekämpfung in den Betrieben unerlässlich. Derzeit gibt es noch keine gleichwertige Alternative zu Kupfer- und Schwefelpräparaten bei der Regulierung des Apfelschorfes.    Ziel des Projektes ist es, die bestehenden Verfahren zu optimieren, um mit möglichst geringem Einsatz von Kupfer eine effektive Schorfregulierung zu erreichen. Hierzu soll eine sichere Schorf-bekämpfungsstrategie entwickelt werden, die im Laufe der Schorfsaison auf kupferfreie oder kup-ferminimierte Präparate zurückgreift. Dafür ist es notwendig die Parameter der einzelnen Alternati-ven genau zu erarbeiten. Es soll...

Die Wirkung von Myco-Sin gegen den Apfelschorf in Abhängigkeit der Schwefelformulierung
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Böger, N.; Fuchs, Jacques G.
Schlussfolgerungen:   Zur Regulierung von Apfelschorf in kühlen Phasen im Frühjahr sollte Myco-Sin auf keinen Fall ohne Schwefelzusatz verwendet werden.   Netzschwefel Stulln ist als Mischungspartner zu Myco-Sin besser geeignet als Thiovit. Netzschwefel Stulln ist per 2004 im Biolandbau zugelassen.   Zahlreiche Versuche zeigen, dass die Schorfwirkung von Tonerde + Schwefel besser ist als von Netzschwefel alleine.

Effects of crop mixtures on pest of faba bean under organic agritultural conditions
Provedor de dados: 21
Autores: Fernandez-Aparicio, M.; Jørnsgård, B.; Rubiales, D.
Faba bean could be a popular break crop in organic agriculture but serious attack from the black bean aphid (Aphis fabae Scopoli) can reduce the yield significantly. Field experiments performed under organic conditions showed that aphid attack is reduced when faba bean is intercropped with triticale and wheat, On the contrary, damage by weebil (Sitona lineatus L.) and pod borer (Heliothis armigera Hübner) was not reducer or even increased.

Autores: Cooper, J.M.; Schmidt, C.S.; Lueck, L.; Shotton, P.N.; Leifert, C.
The Nafferton Factorial Systems Comparison (NFSC) experiments are part of a long-term field trial that compares organic and conventional systems of crop rotation, crop protection and fertility management, in a factorial design.  Pest and disease incidence in vegetables in the 2005, 2006 and 2007 season are reported.  Cabbage root fly damage was always reduced under organic crop protection, but there were no consistent trends for the effects of fertility management on this pest.  Sclerotinia in lettuce was consistently higher under conventional fertility management.  Blight in potatoes was enhanced in the 2007 season by the combination of conventional fertility management and organic crop protection practices.  Mechanisms for these effects, including the...

Effektiv og systematisk bejdsning af størstedelen af den danske såsæd har medført, at alvorlige og tabsgivende frøbårne sygdomme har været holdt på et meget lavt niveau. En stor del af sædekornet (85-90%) bejdses i dag, mens bejdsning af andre afgrøder varierer en del afhængig af den aktuelle forekomst af sygdomme. Det samlede forbrug af bejdsemidler (fungicider og insekticider ) ligger i størrelsesordenen 80-110 t virksomt stof ( i 1994 11-12 % af det samlede fungicid og insekticidforbrug eller omkring 3 % af det samlede pesticidforbrug). Sygdommene er, trods denne systematiske indsats, ikke udryddet, men kun holdt på et lavt niveau. I en fremtidig dyrkningspraksis uden effektiv bekæmpelse af frøbårne sygdomme, ville en række alvorlige sygdomme relativt...

The soil borne pathogen Rhizoctonia solani is of increasing importance since organic seed potatoes are compulsory in organic potato production. No convincing measure to control the disease is available for organic production. The effect of a suppressive compost mixture of organic household and yard waste to control R. solani in potatoes was tested in an organic field trial at the University Kassel in 2006. The compost was directly applied at the seed tuber area. Seed tubers (variety Nicola) naturally infested with black scurf were planted in three infection classes (no, middle and high infection).  Compost amendment had a strong impact on symptoms of R. solani on tubers. The reduction of both the infestation of harvested potatoes with black scurf and the...

Virulence pattern in Danish races of common bunt (Tilletia caries) Common Bunt
Provedor de dados: 21
Autores: Borgen, Anders.
Spores of common bunt (Tilletia caries) was sampled from different places in Denmark in 2000-2005 and maintained as a bulk sample on susceptible varieties. In 2011 and 2012, spores were harvested from selected infected varieties, and used to reinoculate the same variety from where they were harvested. 98 out of 240 tested varietes had an increase of infection from this inoculation method compared with infection from the bulk spore sample. This is interpreted as a sign of virulence development. Using this method on the differential varieties for bunt resistance and other varieties with known bunt resistance genes indicated that virulence races were present able to infect varieties having resistance genes Bt-1, Bt-2, Bt-3, Bt-4 Bt-5, Bt-7, Bt-8, Bt-10 and...

L'objet premier du projet est la protection durable des végétaux contre les bioagresseurs invasifs dans les vergers et les vignes dans le Rhin supérieur. Le point fort est la Drosophila suzukii.  Le projet revêt une importance particulière: les petites parcelles des vignobles et des vergers avec leurs structures accompagnantes sont typiques pour la région du Rhin supérieur. Elles abritent une grande diversité d'espèces de flore et faune, mais aussi fournissent des abris et de la nourriture aux espèces invasives. De plus, la région se caractérise par un climat chaud qui convient bien à ces bioagresseurs invasifs qui ne connaissent pas les frontières.     La coopération transfrontalière est donc essentielle pour atteindre les objectifs fixés.    Partenaires:...

Autores: Fittje, Susanne; Menzel, Dr. Wulf; Saucke, Dr. Helmut; Vetten, Dr. Heinrich-Josef.
An apparently new virus disease of carrots (Daucus carota) has gained increasing importance in Germany. The complex of symptoms consisting of leaf reddening, plant stunting, hairy and rat tailed roots is thought to be caused by viral infections. Particularly the main carrot growing areas in Lower Saxony are adversely affected. In field surveys in 2003 about 30 % symptomatic plants were observed with average weight losses of about 30 %. In severe cases symptom-related yield reduction was estimated to be 17 % on-farm, which corresponded to a monetary loss of up to 600 €/ha. In 2004 up to 6 % of the plants displayed virus like symptoms. Varietal differences in susceptibility were observed. In general, late maturing varieties for processing showed more...

Scab-resistant apple varieties are urgently required in ecological fruit growing in the Lake  Constance region. In the season 2007 more than 60 scab-resistant varieties were  investigated concerning their sensibility to sooty blotch. Apart the influence of harvest  periods (early or late) the investigations show an influence of the cross parents of new  varieties. Varieties with Topaz as one parent were much more sensitive to sooty blotch  than varieties with Florina as cross partner.

Ukrudtsbekæmpelse og sygdomme i lupin
Provedor de dados: 21
Autores: Rasmussen, Henrik.
Økologisk Rådgivning har i år gennemført et landsforsøg med ukrudtsbekæmpelse i lupin. I forsøget er der sået med to forskellige rækkeafstande, og ukrudtsbekæmpelse er sket med strigling, radrensning eller kombination heraf.  Forsøgsbehandlingerne fremgår af tabel 1. Forsøget var med den uforgrenede sort Prima på en fin sandblandet lerjord (JB6). Forsøget er sået sent (2. maj), og såbeddet var tørt. Dette bevirkede sammen med den efterfølgende regn, at lupinerne spirede meget uens frem. Dette gjorde det meget svært at ramme lupinernes optimale stadium for ukrudtsbekæmpelse. Den megen regn besværliggjorde også ukrudtsbekæmpelsen.

Ryania Speciosa: an insecticide for organic orchards?
Provedor de dados: 21
Autores: Kelderer, Markus; Sgarbossa, Manuela; Schönweger, Gudrun; Elias, Ellen; Roland, Zelger; Santer, Johann; Stuppner, Hermann.
Ryania speciosa is a grove belonging to the family Flacourtiacea, located in tropical  climates in Central- and South- America. The Indigenous population used the plant, which  contains toxic alkaloids, against cockroaches. In the forties the ground wood was used as  insecticide against different pests. In the first version of annex 2b from the EC regulation  2092/91, Ryania was still listed, but it was subsequently cancelled due to its lack of  registration as a pesticide in any European country. In organic farming, only a few  insecticides are allowed, but in orchards there is a permanent need to control larvae such  as coddling moth, etc. The Italian Ministry of Agriculture initiated a survey to investigate  the possibility of developing an 'organic'...

For a precise diagnosis of the wheat bunt diseases, common bunt and dwarf bunt (Tilletia spp.), reliable and reproducible methods are essential. Further the accurate  quantification of the spore number on infested seed is important for seed multiplication and international seed trading, as different thresholds and quarantine regulations have to be considered. At present the determination of the teliospores is carried out according to a filtration method (ISTA 1984) combined with a microscopic examination requiring considerable experience to distinguish the different Tilletia species. Therefore the aim of this research work is to develop an efficient molecular testing  method by means of quantitative Real-time PCR (qPCR). Based on genome data species...

Effects of extra floral and floral nectar of Centaurea cyanus on the parasitoid wasp Microplitis mediator: Olfactory attractiveness and parasitization rates
Provedor de dados: 21
Autores: Géneau, Céline E.; Wäckers, Felix L.; Luka, Henryk; Balmer, Oliver.
Nectar is an important food source for adult parasitoids and can increase their longevity and fecundity and hence their parasitization rate. Both floral and extrafloral nectar are used as food sources by parasitoids. While floralnectar exploitation by parasitoids has been extensive lystudied, little is known on how parasitoid slocate extrafloral nectar,nor whether the availability ofextrafloral nectar increases parasitization of pests in the field. We conducted aY-tube olfactomete rexperiment to determine if the parasitoid Microplitis mediator utilizes olfactory cues tolocate the extrafloral nectar of Centaurea cyanus. Inaddition, weperformed asemi-fieldexperiment to investigate whether M.mediator are differentially attracted by C.cyanus offering...

Investigations on the occurrence of wheat bugs (Scutelleridae, Pentatomidae; Heteroptera) in organic farming of Eastern Austria
Provedor de dados: 21
Autores: Grünbacher, Mag. Eva Maria; Kromp, Dr. Bernhard.
Wheat bugs, an umbrella term for a set of different species, damage wheat by sucking on semi-ripe grains. The proteolytic enzyme inserted with the saliva destroys the gluten. If more than 1.5 – 2% of the grains are infected, the ground wheat loses its baking quality. In 2003, for the first time since the fifties, a significant occurrence of wheat bugs was recorded in Eastern Austria. Since in organic farming no insecticides are available for direct control, the farmers were advised to grow quality wheat at the greatest possible distance to fallows, windbreaks and other uncultivated areas. To clarify their significance for the wheat bug occurrence, a diploma thesis was performed in the year 2004. The sampling sites were situated in Burgenland, Eastern...

Autores: Flügel, Hans-Joachim; Luka, Henryk.
Der Verlust an Biodiversität durch die moderne agroindustrielle Landwirtschaft mit ihrem massiven Pestizideinsatz ist heute ein immer größer werdendes Problem. Es gibt deshalb Versuche, den Pestizideinsatz zu reduzieren. Dazu gehört auch die Einbeziehung von wildlebenden Pflanzen, Tieren und sonstigen Organismen in den landwirtschaftlichen Produktionsprozess. Am Beispiel des Kohlanbaus werden die Ergebnisse von Versuchen mit Blühstreifen und Begleitpflanzen zur Förderung von Nützlingen dargestellt. Daneben werden weitere Hilfsorganismen aus der Klasse der Insekten tabellarisch aufgeführt. Die Ergebnisse zeigen, dass dadurch nicht nur der Ertrag gesichert, sondern auch die Artenvielfalt auf dem Acker erhöht werden kann.

The aim of the project is to use an ecological approach to analyse the interactions of a range of key agronomic variables in organic wheat production (wheat genotype, spatial arrangement of seed, seed density and wheat/white clover bi-cropping) to determine an optimal approach to improved and stabilised production. The fi rst set of data revealed that seedling competition was infl uenced by seed rate and drilling arrangement. Furthermore, the variety Hereward had increased emergence and establishment to Aristos. An interaction exists between wheat variety, seed rate and drilling arrangement on the level of canopy cover at different developmental stages – these factors are important for the suppression of weeds.

The growth inhibiting effect of four commercially available grapefruit seed extracts  on the causal organism of apple scab  Venturia inaequalis was tested. Germination of  the conidia of Venturia inaequalis was pronouncedly inhibited by all tested extracts.  The commercial products were analyzed by high pressure liquid chromatography and  thin layer chromatography. All samples contained at least one preserving agent.  These substances were identified as either benzethonium chloride, benzalkonium  chloride, methyl parabene or propyl parabene. Freshly prepared extracts from seeds  of grapefruits (Citrus paradisi) did not inhibit the germination of Venturia inaequalis. It  was therefore concluded that the antifungal effect of grapefruit seed extracts is...

Fireblight (Erwinia amylovora) was detected on rootstocks in several apple orchards in Baden-Württemberg.  In Germany the mostly used rootstocks on apple ‘M9’ and ‘M26’ are known to be susceptible to fire blight.  Therefore the LVWO Weinsberg participated in the “European Cornell-Geneva rootstocks trial” which is a  common experiment of seven research institutes over whole Europe. Six fire blight resistant or tolerant rootstocks  from the Geneva® breeding program were tested in comparison to ‘M9’ (Type T337 and Pajam 2).  The variety was ‘Golden Delicious’ and the trees were planted in 2001 . An outstanding new rootstock was  ‘Geneva® 11’. The tree size was similar to ‘M9’ (above 7% more growth in comparison to ‘T337’). Besides  that the influence on the...

In an organic orchard with a codling moth (CM) population less susceptible to CpGV it was tested,  whether an increased dosage of CpGV by factor 10 would result in any increased efficacy.  The applications were set in shorter than weekly intervals with 10 ml/ha Madex (low dosage plot)  and 100 ml/ha Madex (high dosage plot). The higher dosage showed also a better efficacy, especially  on the “active damage” (live larvae).  The orchard where the experiments were conducted was known to have a less susceptible CM  population (2004) although there were no serious CM problems reported by the farmer despite the  CM control was done only with CpGV. It was investigated, whether natural antagonists might have  been a reason for the absence of serious problems in...

RAPD markers for the characterization of the olive fruit fly parasitoid Opius concolor (Spzel.) used in biological control programs.
Provedor de dados: 21
Autores: ALBAKRI, Mamoun.
The endoparasitoid Opius concolor (Spzel.) has been used as a biological control agent in the biological control programs of the olive fruit fly, which consists of massive releases of parasitoid in fields where indigenous wild types are present. Field differentiation between the released and the indigenous parasitoids, and the estimation of the proportion of released individuals in the overall field population are a prerequisite to estimate the efficiency of the biological control programs. Because wild and released parasitoids are morphologically indistinguishable, a DNA molecular technique, based on Polymerase chain reaction (PCR), the Random Amplified Polymorphic DNA (RAPD-PCR) was used to differentiate between five different populations of this...

Erarbeitung von Schwellenwerten zur wirksamen Bekämpfung von Zwergsteinbrand (Tilletia controversa) und Steinbrand (Tilletia caries) sowie deren praktische Umsetzung im Öko-Landbau
Provedor de dados: 21
Steinbrand und neuerdings auch Zwergsteinbrand entwickelt sich zunehmend zu einem Problem im ökologischen Weizen- und Dinkelanbau. Mit Brandbutten / Brandsporen belastetes Getreide kann weder zu Saat-, zu Back- oder zu Futterzwecken verwendet werden. Eine Verbreitung kann sowohl über das Saatgut als auch über den Boden erfolgen. Neuste Untersuchungen zeigen, dass insbesondere der Zwergsteinbrand, der ursprünglich in höheren Lagen über 1000 m zu finden war, sich zunehmend bis auf 400 m Meereshöhe ausbreitet. Verbindliche Grenzwerte, die eine Einschätzung des Risikos zulassen, existieren noch nicht. Bei der Suche nach Möglichkeiten zur Eindämmung wurden in der Vergangenheit bereits Projekte zur Züchtung toleranter bzw. resistenter Sorten initiiert. Aktueller...

Praxiserfahrungen mit Naturalis-L zur Regulierung der Kirschenfliege im Jahr 2009
Provedor de dados: 21
Autores: Daniel, Claudia; Häseli, Andreas.
Der Erfolg des Naturalis-Einsatzes zur Regulierung der Kirschenfliege wurde im Jahr 2009 auf sieben Praxisbetrieben begleitet. Auf drei Betrieben wurden befriedigende Resultate erzielt. Bei zwei Betrieben ist die ungenügende Wirkung auf klare Anwendungsfehler zurückzuführen. Die schlechten Resultate auf zwei weiteren Betrieb sind im Moment nicht abschliessend begründbar. Die Situation auf diesen Betrieben sollte im nächsten Jahr besser überwacht werden. Hauptfehlerquellen waren die extakte Bestimmung des Flugbeginns (Gelbfallen häufig zu spät oder gar nicht montiert) und die zu langen Abstände zwischen den Spritzungen, sowie zwischen der letzten Spritzung und der Ernte.

Tiefflieger über Schweizer Gemüsefeldern
Provedor de dados: 21
Autores: Wyss, Eric; Daniel, Claudia.
Viele wichtige Gemüseschädlinge, wie zum Beispiel die Möhrenfliege, die Kleine Kohlfliege und die Kohldrehherzgallmücke, sind ausgesprochene Tiefflieger, das heisst sie bewegen sich in oder nur knapp über der Vegetation fort. Mit vertikal stehenden Netzen, so genannten Insektenzäunen, können diese Schädlinge am Einflug in die Kultur gehindert werden.   Als wichtigste Schlussfolgerung aus den Versuchen in den Jahren 2002 und 2003 lässt sich sagen, dass die Insektenzäune gegenüber den bekannten Kulturschutznetzen entscheidende Vorteile bieten: (1) Kein Aufliegen der Netze auf der Kultur. (2) Keine Beeinflussung des Mikroklimas und damit weniger Probleme mit Krankheiten. (3) Weniger Aufwand durch einfacheres Öffnen der Zäune an den Stirnseiten der Felder bei...

Provedor de dados: 21
Autores: Rau, Florian; Weier, Ulrike; Krebs, Kurt-Ernst; Jahn, Marga.
Teilversuch 1  Die Ergebnisse des ersten Versuchsjahres zeigen, dass es Unterschiede im Befall des Saatgutes mit  Möhrenschwärze (Alternaria dauci) und Sortenunterschiede im Auftreten der Krankheit auf dem Feld gibt. Ob die unterschiedlichen Befallsstärken auf dem Feld auf einen unterschiedlich starken Ausgangsbefall des Saatgutes zurückzuführen sind muss weiter geprüft werden.   Das Ertragspotential der Sorten war unterschiedlich, die stärksten Sorten erreichten etwa den doppelten Ertrag der schwächsten Sorte.  Starke Laubschädigungen durch Alternaria führten tendenziell zu erhöhten Nitratgehalten im Erntegut. Hier kann – je nach Vermarktungsweg – eine frühere Ernte für die Praxis empfehlenswert sein.

Autores: Wendling, G.F.D.
The use of different tillage systems and winter crop plants over a long period of time on a clayed and naturally acid soil can promote changes in the forms of aluminum present in the soil, reducing the possibility of its toxicity to major crops. The aim of this study was to evaluate different forms of aluminum in a Oxisol in an experiment conducted by IAPAR (Southwest of Paraná) for 23 years. In the region, which was originally covered by Atlantic Forest, two systems of tillage (no-tillage (NT) and Conventional Planting System (CPS) were employed using the cultivation of six different species of winter plants (lupine blue, hairy vetch, black oats, turnip, wheat and fallow) in sequence to soybean and corn in the summer. In October 2009, there was the...

The restriction on the use of copper salt fixed by the European Community (Reg. EC n. 473/2002) owing to the environment problems due to the copper accumulation in the soil, has stimulated the research to evaluate the possibility to reduce the copper use. This field experiment was carried out to estimate, in an organic vineyard, the effectiveness, against Plasmopara viticola (Berk. et Curt) Berl. et  De Toni, of copper compounds at a low rate or alternative copper products. Guideline EPPO/OEPP PP 1/3 (2) has been used. Plots of 18 plants each, repeated 4 times in a randomized design, have been arranged.

Ecology of the ochratoxin A producing Penicillium verrucosum: Occurrence in field soil and grain with special attention to farming system and on-farm drying practices
Provedor de dados: 21
Autores: Elmholt, Susanne.
Mycotoxin contamination of organically grown cereals has been a growing concern during recent years, one of the most important being ochratoxin A (OTA). In countries with a temperate, humid climate, OTA is produced by Penicillium verrucosum and it is crucial to focus on the fungus to obviate problems. This paper presents results to elucidate different aspects of the ecology of P. verrucosum. In a survey of differently farmed soils, P. verrucosum was found in 11 out of  65 soils (35% of the organically and 7% of the conventionally cultivated), these being the first reports of its natural occurrence in soil. Except for two soils it was found with low frequencies (100-300 cfu g dry soil-1), and the results point to home grown seed as a potential risk of soil...

Consumers have become more aware of healthy and safe food produced with low environmental impact. We studied the quality of wheat (Triticum aestivum L., winter form) grown in a 21-year agro-system comparison between organic and conventional farming in Central Europe, known as the DOK experiment.    The 71% lower addition by plant available nitrogen to the organic field plots led to 14% lower wheat yields. However, the nutritional value, i.e. protein content and baking quality, were hardly affected by the farming systems. Despite exclusion of fungicides from the organic production systems, the quantities of mycotoxins detected in wheat grains did not differ. Food preference tests, as an integrative method, indicated a tendency for rats to prefer organically...

The C.R.A. Experimental Institute for Olive Growing has been performing for many years the study of olive germplasm in order to identify genetic resistance sources to the olive parasites. Some pathogens are particularly noxious for olive table production because they attack and disfigure the outward appearance of the fruits. Camarosporium dalmaticum (Thum) is a pathogen widespread in Southern Italy determining the olive fruit rot in many genotypes particularly susceptible to its infection. The object of the present study is an investigation carried out in Calabria in an experimental field, analysing 25 cvs cultivated under the same environmental and growing conditions. The observations were performed on olive fruit samples (200 per thesis) and the...

Brassica juncea è una pianta annuale appartenente alla famiglia delle Cruciferae, usata nelle nostre aree come coltura da sovescio, sia per aumentare la sostanza organica, che per la biofumigazione del terreno. Ci sono alcuni sistemi di protezione naturali, basati sulla produzione di molecole con attività biologica contro fitopatie e fitofagi. Nella famiglia Brassicaceae esiste il sistema chimico Glucosinolati (GLS) - Mirosinasi il quale è capace di generare composti tossici per funghi patogeni e nematodi. Durante il 2003 e il 2004, il C.R.A.B. ha testato le opportunità d'uso di Brassica juncea come biofumigante. L'azione degli isotiocianati presenti in B. juncea risulta funzionare anche contro i semi delle infestanti presenti nel terreno. Negli ultimi...

Abstract: The effect of exclusion fences on the colonization of broccoli and kohlrabi by the Swede midge, Contarinia nasturtii (Diptera: Cecidomyiidae).  The Swede midge Contarinia nasturtii (Diptera: Cecidomyiidae) is an important and wide spread pest in Europe. In Swiss organic vegetable production only the expensive product “Audienz“ (active matter: Spinosad) is permitted. In addition, netting the entire crop surface can exclude the Swede midges from crops, but it has a negative influence on the microclimatic conditions and the labour and capital cost are often too high. Since it is known, that several vegetable key pest species spread within the crop or only a few centimetres above it, the use of vertical exclusion fences has been developed in Canada....

This trial took place in an organic fruit growing farm located near Lake Constance with the variety ‘Elstar’  planted in 1995. In 2004 and 2005 one variant (control) was pruned normally during the winter, the other  variant was pruned more intensively to reduce the amount of flower buds. In 2004 at both variants the number  of apples was reduced to 165 apples/tree at the end of May. Time for thinning by hand was cut down  significantly in the intensively pruned variant. In addition at harvest the number of apples with bigger diameters,  especially 75-80 mm, increased. Moreover the number of flower buds for the next season rose by 20 %.  Therefore in 2005 the yield per tree at the intensively pruned variant increased about 15 %, but also the  working hours...

Potatoes are one of the most important crops in organic farming with respect to farmers’ income. Yields are often strongly influenced by regional and yearly diffe-rences. Despite the availability of detailed knowledge, it is only now that a crop growth model has been generated which allows for the estimation and prediction of potato yield under organic conditions. The aim of our study was to produce a highly elaborate prediction model based on the utilization and speed of nitrogen uptake as they relate to the yield dynamics of tubers and canopy in combination with late blight dynamics. Therefore, from 2005 to 2014, these parameters were assessed in up to 18 varieties of potatoes comprised of differing maturity groups. The data were ana-lyzed in R using...

Evaluation of an active mating disruption concept against codling moth (Cydia pomonella) under the aspects of different application systems and varieties
Provedor de dados: 21
Autores: Schildberger, B.; Wurm, L.; Kickenweiz, M.
Beside standard systems of mating disruption the activity of the product Exosex CM and  Exosex 2 CM under the aspect of different application systems and several varieties were  tested at the research station of the Federal College and Institute for Viticulture and  Pomology Klosterneuburg. Male insects were attracted into the Exosex dispenser by using  the appropriate pheromone, which acts on the pheromone receptive sensors on the male  so that they cannot locate calling females. Standard mating disruption techniques usually  rely on the introduction of amounts of pheromone emitted by natural populations of pest  species into the atmosphere. Exosex CM significantly reduces deployment time and labour  costs in the orchards, additionally the flexibility to...

Late blight of potatoes, caused by Phytophthora infestans, is particularly difficult to prevent or control in organic agriculture. In this study, the host resistance of selected varieties to foliar and tuber blight and their yield under organic growing conditions were assessed in trials carried out in four countries (Switzerland, France, England and Norway) in 2001 and 2002. The objective was to identify new, more resistant varieties which might replace some of the more susceptible varieties which are currently grown in organic agriculture. In each country, five test varieties were compared with two reference varieties, identical for all sites, and with two locally popular varieties. In addition, the effect of copper fungicides was assessed for all...

Autores: Holopainen, Jarmo K.
Compared to conventional farming the pest management strategies in organic farming is based on better plant resistance and sustainable cultivation technique that does not destroy the natural enemies of pest insects. Methods that reduce feeding efforts of pests and maintain strong population of predators and parasitoid on crop plant, are the way forward for sustainable plant protection strategies. Volatile compounds extracted from plants and sprayed on crop plants are one of the key factors for the development of these techniques.

Effekten av tre ulike konserveringsmetoder for bygg på fôropptak og melkekvalitet i økologisk landbruk ble testet i et fôringsforsøk med cross over design med tre perioder á en uke. Kyrne ble tildelt 6,0 kg TS (førstekalvskyr 5,0 kg TS) av enten tørket bygg (Arve), valset bygg ensilert med melasse, eller valset bygg ensilert med syrer. I tillegg til bygg ble kyrne tildelt grassurfôr ad libitum og en mineral/vitamin-blanding. Forsøket ble gjennomført i Bodø i mars 2004.  Alle de tre metodene konserverte bygget godt. Konserveringsmetoden hadde ingen innvirkning på det totale fôropptaket. Kyrne var i sen laktasjon og melkeproduksjonen var lav, men det var ingen forskjell i ytelse mellom konserveringsmetodene for bygg. Innholdet av råprotein var lavt i...

Neem-Azal T/S to control leafhoppers and aphids in greenhouse sweet pepper and tomato.
Provedor de dados: 21
Autores: Daniel, Claudia; Koller, Martin; Wyss, Eric.
Aphids and leafhoppers can cause heavy damage to sweet pepper (Capsicum annuum) and tomato (Solanum lycopersicum). Neem-Azal T/S was therefore evaluated in greenhouse experiments for leafhopper and aphid control.   In 2005, five organic greenhouse compartments were treated with Neem-Azal T/S (0.2%, 1000-1500 L water ha-1; two treatments on tomato; three treatments on sweet pepper) for control of leafhoppers; four greenhouse compartments were left as untreated controls. Leafhopper flight activity was monitored using yellow sticky traps. Leaf damage was estimated by evaluating the fifth leaf from the top of the plant on 100 plants per plot. Flight activity was reduced by 80% (Abbott’s formula; 11-20 days after the 2nd treatment) to 93% (60-75 days after last...

Quantification of leaf stripe, Pyrenophora graminea, in barley seed by real-time PCR
Provedor de dados: 21
Autores: Justesen, A.F.; Hansen, H.J.; Pinnschmidt, H.
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P. graminea (barley leaf stripe), which causes rejection of seed lots. A real-time PCR method for detection and quantification of P. graminea has been developed.

Provedor de dados: 21
Autores: Parisi, Luciana; Gros, Christophe; Combe, Freddy; Parveaud, Claude-Eric; Gomez, Christelle; Brun, Laurent.
The impact of a cultivar mixture within the rows including the cvs Melrouge (low susceptibility to scab) and Pitchounette (Rvi6 resistant) was assessed during 2008e2009 in an organic apple orchard located in Rhône Valley (Drôme, France), on three important pests and diseases: scab, powdery mildew and rosy apple aphid. In this area, the resistance of Rvi6 gene was effective since the orchard plantation in 2004. The impact of the cultivar mixture was assessed per se, but also associated with sanitation practices to decrease the primary inoculum of scab and mildew, and compared to disease development on pure stands of Melrouge. The cultivar mixture showed a good efficiency to decrease the scab incidence on leaves and fruits; a significant effect on scab...

Biocontrol zur Regulierung der Kirschfruchtfliege
Provedor de dados: 21
Regulierung der Kirschfruchtfliege im biologischen Anbau: Prüfung von entomopathogenen Pilzen in Labor- und Feldversuchen.  Die Kirschfruchtfliege Rhagoletis cerasi Loew (Diptera: Tephritidae) ist der wichtigste Schädling im Süsskirschenanbau in Europa. Bei unbehandelten Bäumen können bis zu 100% der Kirschen Madenbefall aufweisen. Da Handel und Verbraucher nur einen Befall von maximal 2% tolerieren, sind effiziente Bekämpfungsmassnahmen gefragt. Im biologischen Anbau ist eine Bekämpfung derzeit nur mit Leimfallen oder durch den Einsatz von Netzen möglich. Beide Methoden sind sehr arbeitsintensiv und oft nicht ausreichend wirksam. Der Einsatz von Mikroorganismen als Biocontrol-Massnahme könnte eine Alternative darstellen. In Laborversuchen wurden mehrere...

Fruit thinning in organic apple growing with optimized timing and combinations strategies including (new) natural spray products and mechanical rope-divices
Provedor de dados: 21
Autores: Weibel, Franco P.; Chevillat, Véronique S.; Tschabold, Jean-Luc; Stadler, Walter.
The aim of our study was to find new thinning methods for organic apple production able to fulfil the standards of Bio-Suisse, the main label organisation of the organic food sector in Switzerland. The 14 trials reported were carried out during flowering period in 2003 and 2004 on the cultivars Pinova, Gala, Maigold, Elstar, Golden Delicious and Otava at different sites. The results confirm the good efficiency of mechanical thinning with the rope thinner and the thinning potential of vinasse, a by-product of molasses.  Different vinasse products were tested (K-Vinasse, light-vinasse, N-Vinasse) and it was observed that those containing less nitrogen had a minor thinning effect. To avoid phytotoxicity on leaves, the concentration of NVinasse should not...

Competitive ability of Rumex obtusifolius against native grassland species: above- and belowground allocation of biomass and nutrients
Provedor de dados: 21
Autores: Zaller, Johann G.
Understanding the competitive ability of Rumex obtusifolius against grassland species is essential for developing efficient control strategies against docks. Here we present results from a greenhouse experiment where we tested shoot and root competition between Rumex regenerating from rhizome fragments and grassland species (grasses, herbaceous and leguminous species). Competitive ability was expressed as the relative above- and belowground biomass partitioning and, concentrations and allocation of carbon and nitrogen of the plant species studied. Regeneration of Rumex was significantly affected by  competition through neighbouring native grassland species. Rumex responded to concurrent shoot and root competition of grassland species with 50% more...

Evaluierung von Brassicaceae auf Resistenz gegen die Mehlige Kohlblattlaus (Brevicoryne brassicae) als Basis zur Nutzung blattlausresistenter Kohlsorten für den ökologischen Landbau
Provedor de dados: 21
Autores: Bundesanstalt für Züchtungsforschung an Kulturpflanzen, Institut für Epidemiologie und Resistenz.
Die Mehlige Kohlblattlaus ist sowohl im konventionellen als auch im ökologischen Landbau ein wirtschaftlich bedeutender Schädling des Gemüsekohls. Im ökologischem Anbau ist die Bekämpfung der Blattlaus sehr schwierig, gleichzeitig hat aber in den vergangenen Jahren der Befallsdruck infolge der Ausweitung des Rapsanbaues als nachwachsender Rohstoff zugenommen. Daher ist es notwendig, Gemüsekohlgenotypen mit Blattlausresistenz zu finden bzw. mögliche Resistenz im Rahmen der ökologischen Züchtung in die Sorten zu übertragen. Bisher sind keine vollständig resistenten Sorten bekannt, lediglich graduelle Unterschiede im Befall  wurden gefunden. In Gewächshausprüfungen wurden aus 275 evaluierten Genotypen 20 selektiert, auf denen nach 14 Tagen die...

Effekt af tekstur og struktur på roddybden
Provedor de dados: 21
Autores: Munkholm, Lars J.; Andersen, Mathias N.
Dybdegående rodvækst giver en række fordele både i relation til planteproduktion og miljø. Der kan opnås en bedre udnyttelse af næringsstoffer og vand, et øget potentiale for biologisk omsætning i dybere jordlag og der ophobes kulstof i dybere jordlag. Rodudviklingen er i høj grad betinget af naturgrundlaget ( klima, jordtype og jordbundsudvikling), men afhænger også stærkt af dyrkningen (jordbearbejdning, trafik, gødskning, vanding, dræning,, kalkning mv.). Jordfysiske faktorer er ofte af dominerende betydning for rodudviklingen i dyrkede jorde. Mekanisk modstand har meget stor betydning for rodvæksthastighed og –nedtrængning, men er samtidig en meget sammensat størrelse, som påvirkes af bl.a. tekstur, struktur, volumenvægt og vandindhold, der igen...

Autores: Knudsen, Jens; Larsen, John; Bødker, Lars; Jørnsgård, Bjarne; Jensen, Birgit.
The possibility of improving resistance in pea against the root pathogen Aphanomyces euteiches using composite cross as a breeding and selection method was examined. In order to maintain acceptable agricultural features and high yield 6 out of the 8 parental varieties in the present composite-cross were commercially grown varieties. Populations of the composite cross were grown up to five generations with selection pressure in soil heavily infested with pea root pathogens or without selection pressure on soil free of pea root pathogens. Yield of populations of the F9 and F10 generations of the composite cross grown with selection pressure was on average 35% higher than that of the population obtained without selection pressure as well as the average yield...

Soil properties, crop yield and quality with farmyard manure with and without biodynamic preparations and with inorganic fertilizers
Provedor de dados: 21
Autores: Raupp, Joachim; Oltmanns, Meike.
Since 1980 a 2 factor fertilization experiment compares 3 fertilization types (farmyard manure with and without biodynamic preparations vs. inorganic fertilizers) applied at 3 different rates in a 4 field crop rotation. Except for fertilization all other elements of cultivation were the same in all treatments and followed normal organic farming practices. The key results of the experiment obtained in more than 2 decades are reported with respect to soil parameters (e.g. organic carbon content, microbial biomass and activity, particulate organic matter, amino acid content, carbon source utilization, micronutrients), crop parameters (yield formation depending upon fertilization and site conditions, mycorrhiza development) and weed abundance.

In vitro screening of the effect of three glucosinolate derived nitriles on soil-borne fungi
Provedor de dados: 21
Autores: Bellostas, Natalia; Casanova, Esther; Garcia-Mina, Jose Maria; Sorensen, Jens Christian; Sorensen, Hilmer.
Glucosinolates are allelochemicals present in all plants of the order Capparales that are hydrolysed by endogenous enzymes (myrosinases) forming a variety of compounds with biological activity. ‘Biofumigation’ is the term used to describe the effect of these compounds on soil-borne pathogens and it has normally been attributed to isothiocyanates. At acidic pH and in the presence of redox co-factors such as glutathione, glucosinolate hydrolysis yields also nitriles, which are more hydrophilic and stable than isothiocyanates.   Three nitriles (allyl-, benzyl- and phenethyl cyanide) were tested against soil borne fungi of economic importance: Aphanomyces euteiches var. pisi, Gaeumannomyces graminis var. tritici and Verticillium dahliae. The nitriles were...

Phenolic compounds and disease resistance of 5 blackcurrant varieties in an organic growing system
Provedor de dados: 21
Autores: Iversen, C.K.; Lindhard Pedersen, H.; Brandt, K.
The field resistance and the concentration of phenolic compounds of five black currant varieties grown under organic conditions were compared. Significant differences between varieties were seen for all of seven quantified hydroxycinnamic acid derivatives. The variety 'Intercontinental' clearly contained the highest level of hydroxycinnamic acid esters and at the same time was the most resistant variety. There seems to be a connection between the content of a caffeoyl-di-quinic acid ester and coumaryl-quinic acid ester and disease resistance under field conditions. The effect of four different growing conditions was much less evident. Analysis of the content of these phenolic acids might be a tool to help choosing the disease resistant varieties that are...

A simulation program for infections by Sooty Blotch was developed based on  literature data and expert judgements. The value of the model as tool for timing  fungicide sprays to control Sooty Blotch was tested in 2003 in two randomized plot  trials, and four “on farm” trials where the treatments where made by the growers.  Disease pressure was relative low due to the warm and dry summer of 2003. Two to  five post infection treatments with lime sulfur or coconut soap aimed at severe  infection periods as indicated by the model provides 72 to 100 % control.

Climate change is assumed to benefit Finnish agriculture by extending the thermal growing season and by milder winters in future. While providing opportunities for Finnish field crop production as new crop species and larger scale use of winter-sown crops, climate change is also amongst the most important global driving forces promoting pest species invasion and establishment into new ranges.

Potato late blight – PLB is the most destructive foliar fungal disease for the crop in Southern Brazil. Organic farmers are in the urge to find ways to minimize losses due to the disease. Thus, the main objective of this study was to evaluate the effect of mulching on potato crop on late blight epidemic reduction using soil mulching. Two experiments were installed for the spring planting, at Lapa, PR. Treatments were with mulching (60 t/ha fresh weight, plant cover composition was mainly of ryegrass, oats, mixed with wild radish) and no mulching. Cultivars Ágata (susceptible) and BRS Ana (moderately resistant) were used in each experiment. Randomized complete blocks with 4 reps was the experimental design. PLB severity was weekly assessed visually on plots...

Eindämmung des Erregers der Anthraknose der Lupine im ökologischen Landbau durch Anbau weniger anfälliger Lupinensorten der drei landwirtschaftlich wichtigen Lupinenarten
Provedor de dados: 21
Autores: Nirenberg, H.I.; Feiler, U.
Das Projekt befasste sich mit einem Sortenscreening von 23 Lupinus albus-, 14 L. luteus- und 21 L. angustifolius-Sorten auf die Reaktion gegenüber einer Infektion mit Colletotrichum lupini var. setosum.  Für die Infektion der Samen wurde der Substrattest, eine Methode, die die Primärinfektion des Pathogens simuliert, genutzt. Der Einfluß der Infektion auf verschiedene Merkmale, wie Überlebensrate der Pflanzen, Symptome, Befallsverlauf und auf den Ertrag wurden bewertet. Die drei Lupinenarten zeigten unterschiedliche Krankheitssymptome. Während die Symptome bei L. luteus und L.angustifolius oft untypisch waren, entwickelten sich bei L. albus bekanntere Anthraknosesymptome. Unterschiedliche Verhaltensweisen der drei Lupinenarten waren auch im Befallsverlauf...

Autores: Wilbois, K.-P.; Spieß, H.; Vogt-Kaute, W.; Waldow, F.; Jahn, M.; Wächter, R.; Koch, E.; Müller, K.-J.; Leopold, J.; Reiners, E.
Mit Inkrafttreten der Verordnung (EG) Nr. 1452/2003 Anfang 2004 werden die Möglichkeiten des Rückgriffs auf nicht ökologisches Saatgut im Ökologischen Landbau einschränkt. Der damit einhergehende vermehrte Einsatz von Öko-Saatgut neben der insgesamt stattfindenden Ausdehnung des Ökologischen Landbaus steigert die Bedeutung gesunden Saatgutes für einen erfolgreichen ökologischen Anbau. Derzeit stehen im Ökologischen Landbau neben präventiven Maßnahmen eine Reihe verschiedener Saatgutbehandlungsverfahren zur Verfügung, die allerdings unterschiedlich weit für die landwirtschaftliche Praxis entwickelt und für den Anbauer sowie Saatgutproduzenten einsetzbar sind. Zu einzelnen Verfahren aus jeder dieser Gruppen liegen erste Ergebnisse vor (Jahn 2002), die...

Organic Horticultural Seed Trials in Wales
Provedor de dados: 21
Autores: Robertshaw, Paul; Hitchings, Roger.
Under the organic standards, producers are required to use organic seed. However, a derogation can be obtained from the appropriate certification body that allows the use of (untreated) non organic seed where appropriate organic material is not available. There are, however, a number of barriers to the wider use of organic seed including:  • Many of the industry’s standard varieties are not available in organic seed. The lifting of the derogation would oblige growers to use varieties of which they had little of no experience  • By extension of the previous point, many popular varieties will no longer be available on the organic markets. It uncertain whether retailers, and in turn their customers, would accept alternative varieties  • There is little...

Provedor de dados: 21
Autores: Morris, Leigh.
This report reviews the development work carried out within the ‘UV Blocking Polythene Trial’ on the organic farm at the Welsh College of Horticulture during the period May 2003 to September 2004. Two tunnels were erected in 2003, one covered in UV blocking ‘Sterilite’ film and the other in the non-UV blocking ‘Super Strength 600’. The salad/brassicas crops grown during the first season under the UV blocking film showed significantly less pest attack (both winged and non-winged pests). Less aphids were present and their ‘flight behaviour’ was greatly reduced under the UV blocking film. The crops under the UV blocking film also appeared to establish quicker and reached a greater final size. Two more tunnels were erected in spring 2004 and covered in...

MAPPING SOIL SPATIAL VARIABILITY AT HIGH DETAIL BY PROXIMAL SENSORS FOR A VINEYARD PLANNING
Provedor de dados: 21
Autores: Priori, S.; L'Abate, G.; Fantappiè, M.; Costantini, E.A.C.
Planning new vineyard needs accurate information about soil features and their spatial variability. The use of soil proximal sensors, coupled by few detailed soil observations and analysis allows to obtain high detailed maps of soil variability at affordable costs. The work showed the methodology to interpolate the proximal sensors data and to delineate homogeneous area by clustering, corresponding to likely soil units. The description and analysis of one profile for each homogeneous area allowed to describe the soil features of each soil typological units and to produce useful thematic maps for vineyard planning.

Susceptibility of different life stages of the European cherry fruit fly, Rhagoletis cerasi, to entomopathogenic fungi
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The effects of six fungus isolates on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae), were assessed in a series of laboratory experiments to find an isolate suitable for biological control. In a first step, the effects of fungus treatments on mortality, mycosis and fecundity of adult flies at a concentration of 107 conidia/ml were evaluated. All fungus isolates caused mycosis but virulence varied considerably among the isolates. Beauveria bassiana and Isaria fumosorosea caused 90–100% mortality and had the strongest influence on fecundity. Metarhizium anisopliae also induced high rates of mortality, while the pathogenicity of Isaria farinosa was low. The effects of lower conidia...

Reduced tillage combined with about 10cm of fresh mulch of a mixture of green peas and rye was compared to a system with conventional tillage with a plow for its effects on disease development of Phytophthora infestans. Within tillage treatments the precrops for potatoes were weedy fallow, vetch (Vicia sativa), or a mixture of oilseed radish and black oats with or without compost application. The Area Under the Disease Progress Curve in the minimum tillage and mulched plots was on average 881 while in the plowed plots it was 1336, a highly significant difference. Yield data are currently being analyzed and will be presented.

The effects of various fertilizers and different compost extracts on crop health and tomato yield were studied in the field in 2004–2005 in two locations in Iran. Treatments included different fertilizers (cattle, sheep and chicken manures, green waste and household composts and chemical fertilizers) and five aqueous extracts (from cattle manure, chicken manure, green-waste and house-hold composts and water as control). The effect of fertilizer type on tomato yield was significant in both locations (P &lt; 0.05). Organic fertilizer use did not obtain higher yields compared to using chemical fertiliser. Generally, chicken manure and green-waste compost led to the highest and lowest tomato yield among different organic fertilizers, respectively. The effect...

Mixed cropping systems for control of weeds and pests in organic oilseed crops
Provedor de dados: 21
Autores: Paulsen, H M; Schochow, M; Ulber, B; Kuhne, S; Rahmann, G.
Agricultural advantages of mixed cropping are gained from biological effects like light competition offering weed-suppressing capacities, or by diversification of plant covers to break development cycles of pests. These effects were measured in a two-year project on mixed cropping with organic oilseed crops. It was found that weeds can be efficiently suppressed in organic linseed (Linum usitatissivum) grown in combination with wheat (Triticum aestivum) or false flax (Camelina sativa). Linseed growth was, however, impaired. In organic pea production (Pisum sativum) also, growing the crop as a mixture with false flax led to a significant decrease of weed population. Either culture showed a balanced plant development. In winter rape (Brassica napus) there...

Autores: Döring, Thomas F.; Heimbach, Udo; Thieme, Thomas; Saucke, Helmut.
Aphids are important pests in potatoes, mainly due to their ability to transmit virus diseases. 17 field experiments were conducted over 4 years at 4 sites on organically managed farms to investigate the effect of straw mulch, applied at various amounts (2–8 t ha-1) shortly after crop emergence, on aphid infestation of potato leaves. The percentage of leaves infested with aphids was repeatedly determined during the growing period in 10 experiments. It was significantly reduced in the mulched treatments at the time around 2 weeks after mulching in 4 experiments, and later, at peak infestation, in 8 experiments. The aphid population size was regularly determined in 11 experiments and was significantly reduced by mulching in 4 of them. In a small scale...

Codling moth populations less susceptible to CpGV: What about higher concentrations?
Provedor de dados: 21
Autores: Kienzle, Jutta; Zebitz, C.P.W.
In an organic orchard with a codling moth (CM) population less susceptible to CpGV it was tested, whether an increased dosage of CpGV by factor 10 would result in any increased efficacy.   The applications were set in shorter than weekly intervals with 10 ml/ha Madex (low dosage plot) and 100 ml/ha Madex (high dosage plot). The higher dosage showed also a better efficacy, espe-cially on the “active damage” (live larvae).   The orchard where the experiments were conducted was known to have a less susceptible CM population (2004)  although there were no serious CM problems reported by the farmer despite the CM control was done only with CpGV. It was investigated, whether natural antagonists might have been a reason for the absence of serious problems in this...

Disease development, yield and baking quality were assessed on the winter wheat cultivars Arina and Capo and their 1:1 mixture in a total of 12 sites on-farm in 2002/2003. Due to a severe drought disease severities were very low and probably had little effect on the plants. The more drought tolerant variety Capo over-yielded in mixtures on average by 21% while Arina yielded in mixtures as expected. Protein and gluten contents and baking volume in pure stands of Arina were usually higher than for Capo. Both varieties changed their quality parameters in mixtures. However, the parameters of the mixtures were not equal to the mean of the pure stands indicating some unknown interactions. The quality parameters of each variety or mixture were compared to the...

Mass trapping Anthonomus rubi and Lygus rugulipennis in strawberries
Provedor de dados: 21
Autores: Sigsgaard, Lene; Trandem, Nina; Fountain, Michelle; Borg-Karlson, Anna-Karin; Hall, David; Cross, Jerry; Ralle, Baiba; Baroffio, Catherine; Wibe, Atle.
The strawberry blossom weevil, Anthonomus rubi, and the European tarnished plant bug,Lygus rugulipennis, can cause substantial damage in organic strawberries in Northern and Central Europe. In conventional production it is also desirable to find alternatives to current pesticide controls, which negatively affects beneficials and also creates a risk of building pesticide resistance. Anthonomus rubi lays an egg in a developing flower bud and then partially bites off the flower stem, resulting in a loss of yield. Lygus rugulipennis nymphs and adults feed on flowers and developing fruitlets, causing a fruit distortion which makes the damaged fruit unmarketable. In the ERA-NET CORE Organic project “Softpest Multitrap”, we studied how pheromone and plant...

Wie lässt sich Drahtwurmfraß an Kartoffeln im Ökologischen Landbau reduzieren?
Provedor de dados: 21
Autores: Schepl, Ute; Paffrath, Andreas.
Wireworms are very important animal pests in ecological farming. Some strategies were tested to regulate wireworm damage in potato farming. Forecrops such as an-nual legumes reduce the damage by wireworms under 10%. Catch crops such as Trifolium resupinatum have a positive impact on the quality of food potatoes. Under-sown crops after the last ridging had no reducing effects. Some potato varieties are more susceptible for wireworm damage. The cultivar ‛Nicola’ had the lowest wireworm damage with about 13%. Wireworm damage arised linear with later harvest dates. Pheromone traps are a good method for controlling beetles flight. Metarhizium ani-sopliae was tested as a biological control agent for wireworms. There was no effect on the wireworms’ population.

Introduction of Aureobasidium pullulans to the phyllosphere of organically grown strawberries with focus on its establishment and interactions with the resident microbiome
Provedor de dados: 21
Autores: Sylla, Justine; Alsanius, Beatrix. W.; Krüger, Erika; Reineke, Annette; Bischoff-Schaefer , Monika; Wohanka, Walter.
Currently, there is little knowledge of the establishment of repeatedly applied biological control agents (BCAs) in the phyllosphere of plants and, in particular, their interactions with the resident microbiome. Under field conditions, the BCA Aureobasidium pullulans was applied as a model organism to organically grown strawberries during two subsequent years (2011, 2012), either as single strain treatment or with the co-application of the entomopathogenic fungus Beauveria bassiana. Fungal and bacterial communities of strawberry leaves were investigated by means of plate counts and 454 pyrosequencing. The establishment of the introduced A. pullulans strains considerably differed between the two years, presumably due to distinct environmental conditions....

Thermal Band Heating for Intra-Row Weed Control
Provedor de dados: 21
Autores: Jørgensen, M.H.; Kristensen, E.F.; Kristensen, J.K.; Melander, B.
Surface steaming of soil is a very energy-intensive process, and consequently, efforts have been made to develop a machine for narrow-band steaming of the soil under and around rows of cultivated plants prior to seeding. The use of this machine may achieve up to 90% energy savings, and will also reduce the amount of damage to the flora and fauna. A special test rig has been developed with the objective of obtaining new information about narrow-band soil steaming. For a detailed analysis of the temperature profile in a cross-section of the processed band, an apparatus has been developed especially to record the temperatures obtained at 63 locations and at seven levels across the ditch. On the basis of the results from the test rig, a prototype band-steamer...

Processed Kaolin as an alternative insecticide against the European pear sucker, Cacopsylla pyri (L.)
Provedor de dados: 21
Autores: Daniel, Claudia; Pfammatter, W; Kehrli, P; Wyss, Eric.
Application of processed kaolin particle film repels insects without lethal effects; hence side effects on beneficial arthropods are low. Processed kaolin may be an alternative to broad-spectrum insecticides used against European pear sucker, Cacopsylla pyri (L.), in organic and conventional pear production.   Trials showed that the processed kaolin showed a very high efficacy, and the population of C. pyri was kept under a damaging level over the whole season. In conclusion, kaolin shows promise as an alternative control for C. pyri in organic and orchards of Integreted Pest Management.

Disease management in organic apple orchards is more than applying the right product at the correct time
Provedor de dados: 21
Autores: Trapman, Marc; Jansonius, Pieter Jans.
The relative importance of diseases on apple is varying with cultivar, management, time,  and climate. Many aspects of the cropping system influence the development of diseases.  The choice of the variety determines the disease management during the lifetime of the  orchard. Cultural practices improve the growth and nutrial status of the tree, and therewith  influence the susceptibility of the plant and fruits to diseases directly. Prolonged growth  can also have an indirect effect by causing a microclimate and growing pattern that  favours infection of tree, leafs and fruits by various diseases. Sanitation measures are  common practise for most organic fruit growers and help to make other measures more  effective by reducing infection inoculums. Despite...

Knowledge transfer to organic fruit industry
Provedor de dados: 21
Autores: Anon,.
Although consumer demand for organic fruit is strong, it is currently the least developed sector of the UK organic industry, represented by only a small number of commercial growers.  One of the main constraints preventing growers becoming more involved in this sector has been the lack of technical information and guidance, resulting in very few growers having the knowhow and confidence to convert.  The aim of this project was to produce technical guides for growers on two of the more important commercial fruit crops in the UK, one entitled ‘Organic Apple Production – pest and disease management’ and the other, ‘Organic Strawberry Production – a grower’s guide.’  These have now been published and the information contained within the two booklets should go...

Development of a method for profiling of volatile organic compounds to monitor heat stress in hot water dipped apples
Provedor de dados: 21
Autores: Himmelboe, Martin.
Storage rot is a major contributor to losses of organic apples due to restrictions in spraying in orchards. Postharvest pre-treatments such as hot water dipping (HWD) have been proven successful to reduce storage rot. However, excessive heat during dipping easily induces heat stress and physiological disorders, which only show up after several weeks of cold storage. To develop further the HWD technology, a method for early detection of physiological disorders is desirable. As apples emit volatile organic compounds (VOCs) in response to stress and ripening, VOC profiling can be a useful tool for detecting the immediate heat stress and latent physiological disorders.  In this study, a selected ion-monitoring program was developed for analyzing VOCs from...

Bevar naturens egen regulering
Provedor de dados: 21
Autores: Meyling, Nicolai V.; Sigsgaard, Lene.
Naturlig regulering af bestande i naturen foregår hele tiden. Derfor bliver langt fra alle potentielle skadedyr til virkelige skadedyr et givet år eller sted. Planteædende insekter reguleres bl.a. via fødekæden; nedefra gennem planten og oppefra ved deres naturlige fjender. Blandt skadedyrenes naturlige fjender er rovinsekter, edderkopper og rovmider, snyltehvepse (samlet kaldet nyttedyr) samt sygdomme af størst betydning for den naturlige regulering. Den intensive landbrugspraksis i det moderne jordbrug har dog reduceret effekten af disse fjender. Den manglende regulering medvirker til de skadedyrangreb, som opleves i forskellige afgrøder. I de seneste år er der skabt en øget interesse for at forstå og anvende disse naturlige reguleringsmekanismer for at...

Potential Response of Soil-Borne Fungal Pathogens Affecting Crops to a Scenario of Climate Change in Europe
Provedor de dados: 21
Autores: Manici, L.; Donatelli, M.; Fumagalli, D.; Lazzari, A.; Bregaglio , S.
A study was carried out on the potential response of soil-borne pathogens causing crop yield losses under a climate change scenario in Europe. A controlled chamber set of experiments was carried out to quantify pathogen response to temperature using pure colonies of three soil-borne fungi, representative of low (Fusarium nivale), medium-high (Athelia rolfsii) and high (Macrophomina phaseolina) temperature requirements. A generic model to simulate fungal growth response to temperature based on these experiments was developed and linked to a soil temperature model component, and to components to simulate soil water content accounting for crop water uptake of potential hosts. Pathogens relative growth was simulated over Europe using the IPCC A1B emission...

Provedor de dados: 21
Autores: Köppler, K.; Kaffer, T.; Vogt, H.
Bait spray experiments against Rhagoletis cerasi were carried out in 2005 to 2007. The  main principle of this method is to use food (e.g. sugar and proteins) as baits for the flies  with small amounts of insecticides, which is applied on parts of the cherry tree. Main focus  was aimed at laboratory and field cage experiments using the commercial GF-120  Naturalyte Fruit Fly BaitTM with the insecticide spinosad, which is registered against North  American cherry fruit fly species in the US and Canada. Furthermore, additional bait spray  formulations as alternatives to GF-120 were used to define the right food bait quality for a  high attractiveness and low reproduction ability. Beyond, the negative effect on  reproduction of flies for azadirachtin (neem)...

In organic cucumber production the infection with downy mildew (Pseudoperonospora  cubensis) is one of the major problems. Use of biological control agents based on  plant extracts and antagonistic micro organisms may be one possibility to control the  disease.  Plant extracts from Salvia officinalis and a plant belonging to the family Fabaceae  (P1), as well as cultures of Brevibacillus brevis showed, in bioassays on potted  cucumber plants, high potential to control the disease with efficacies between 55%  and 100%. For S. officinalis extract the efficacy was close to 100% even at a  concentration of 0.1325%. Initial trials under commercial growing conditions showed  that the control of P. cubensis is better in protected than in open field production. In...

Role of Golden Apple Snail in Organic Rice Cultivation and Weed Management
Provedor de dados: 21
Autores: Joshi, R. C.; Martin, E. C.; Wada, T.; Sebastian, L. S.
The Golden Apple Snail (GAS), Pomacea canaliculata (Lamarck), is a major pest of rice and other aquatic crops in many Asian farms. Farmers’ first line of defense is to use non-specific chemicals for “instant” kill of GAS, without considering its effect on their health, the environment, and non-target organisms. However, some organic rice farmers in Japan, Korea, and the Philippines do not kill GAS but manage them as bio-weeders in rice fields. We evaluated organic farmers’ innovation at the PhilRice Central Experimental Station (CES) using large fields. Then we demonstrated GAS paddy-weeding effects in several farmers’ fields in the Philippines, during the 2003 and 2004 dry (DS) and wet seasons (WS).  Our own experiences and that of the farmers’ in the...

Autores: Seidler-Lozykowska, Dr Katarzyna; Golcz, Dr Anna; Kozik, Dr Elzbieta; Wojcik, Joanna.
In five field experiments the quality of thyme herb and usefulness of Polish cultivar ‘Słoneczko’ for organic cultivation were tested. The following features were tested: dried herb yield, stem content in dried herb, essential oil content, nitrate content, macro- and microelements content and microbiological purity. Only from Słońsk thyme herb yield was higher compared with the yield from conventional cultivation though it contained high amount of stems. Thyme herb was characterized by higher content of essential oil and increased content of macro- and microelements except calcium. Evaluation of microbiological purity showed that for both types of cultivation herb contamination did not exceed standard for raw materials treated with hot water.

Provedor de dados: 21
Autores: Daniel, Claudia; Collier, Rosemary; Thomas, Jane; Hommes, Martin.
Abstract: Pests and pathogens of Brassica vegetables and oilseed rape are mainly managed at a field level. Management of pest insects at a farm level is only suitable for farmers owning compact areas of land, which is not the case in many central European areas. This paper discusses the effects of landscape and region on pests and pathogens in Brassica crops. Topics covered include pest and disease dispersal and persistence, regional races or biotypes, new pests and pathogens, insecticide resistance, conservation biocontrol and monitoring and forecasting.

Observations on the epidemiology of Sooty Blotch in Organic orchards in the Netherlands
Provedor de dados: 21
Autores: Trapman, Marc.
From 2002 to 2005 field observations where made on the occurrence of Sooty Blotch (SB) in unsprayed  orchards on the apple variety Topaz. First SB symptoms in high inoculum orchards where found after on average 639 leaf wetness hours following the first rain 10 days after petal fall. Even then symptoms where present only on places on the fruits that probably stayed wet longer than the leaf wetness sensors have indicated. Weather stations that are set up to register average orchard conditions are unlikely to detect the wetness conditions that lead to SB infections in critical parts of the orchard.  From the delayed symptom development compared to the published data form USA we concluded that un-der Dutch conditions the lower temperature retards the symptom...

Spatio-temporal distribution, combined with aspects of insect biology and ecology can influence the infestation risk of the key pea pest Cydia nigricana in vegetable- and  field peas. The proximity of pea fields of the previous cultivation period highly affects the infestation potential of the moth. The presented study aims to monitor the  infestation development in three different regions in Germany (North Hesse, Saxony, Saxony-Anhalt) in four consecutive years and to relate empirical pest incidences to  key factors as crop abundance, the distance to previous pea fields, the pea plant phenology and climatic conditions. In a next step, these data will form the basis for the  elaboration of a computer-aided decision support system, which assists farmers in...

Influence of compost and digestates on plant growth and health: potentials and limits
Provedor de dados: 21
Autores: Fuchs, Jacques G.; Berner, Alfred; Mayer, Jochen; Smidt, Ena; Schleiss, Konrad.
Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. In order to estimate the potential of Swiss composts to influence soil fertility and plant health, one hundred composts representative of the different composting systems and qualities available on the market were analyzed.  The organic substance and the nutrient content of the composts varied greatly between the composts; the materials of origin were the major factor influencing these values. The respiration rate and enzyme activities also varied greatly, particularly in the youngest composts. These differences decreased when the composts become more mature. Maturity, the degradation stage of the organic matter,...

Vole trapping fences - a new approach to migration barriers
Provedor de dados: 21
Autores: Walther, Bernd; Fuelling, Olaf.
To control problematic vole species in organic orchards farmers can choose between different measures. Some methods like gassing, trapping and even the support of natural  vole antagonists target to reduce vole population by killing individuals. Other methods like protective guards or migration barriers exclude voles from single trees or whole orchards. Recent combinations of the two approaches worked well but had some drawbacks in practice. Nevertheless, efficiency of migration barriers can be improved by attracted natural predators. Here we present first practical experiences and field observations of a  vole-trapping-fence prototype. The new construction consists of prefabricated recyclable polypropylene pieces which are mounted to modules and assembled...

Growing Vegetables Without Irrigation. More locally grown food in semi-arid regions is possible
Provedor de dados: 21
Autores: Quinn, Robert M.
There is a growing conflict between cities and agriculture for fresh water.  To learn what we can grow without irrigation in semi-arid regions, and to demonstrate the potential of a more local food production, I have been experimenting with dry land storage vegetables (potatoes, winter squash and onions) on our organic farm in North Central Montana in the Northern Great Plains of North America.

Aeromonas media in compost amendments contributes to suppression of Pythium ultimum in cress
Provedor de dados: 21
Autores: Oberhaensli, T.; Hofer, V.; Tamm, L.; Fuchs, J. G.; Koller, M.; Herforth-Rahmé, J.; Maurhofer, M.; Thuerig, B.
Soil-borne diseases such as damping-off caused by Pythium sp. are responsible for high yield losses in organic vegetable production and are difficult to control. Compost amendments have been shown to improve in many cases survival and growth of plants in soils infested with soil-borne diseases. Yet, not all composts are disease suppressive and suppressiveness of composts can be pathogen-specific. Cress (Lepidium sativum L.) was grown in a standard peat substrate amended either with coco fiber (conducive control) or with composts differing in their suppressiveness towards Pythium ultimum. Bacteria were isolated from the rhizoplane and the most abundant species identified by MALDI-TOF MS. The bacterial composition in the rhizoplane of plants grown in...

Organic farmers’ reality to manage functional agrobiodiversity in European organic apple orchards
Provedor de dados: 21
Autores: Fernique, Sarah; Penvern, Servane; Cardona, Aurélie; Ahrenfeldt, Erica; Grebeau, D.; Jamar, Laurent; kruzynska, Dorota; Matray, Silvia; Ozoliņa-Pole, Laura; Ralle, Baiba; Sigsgaard, Lene; Steinemann, Beatrice; Świergiel, Weronika; Telfser, Joseph; Warlop, Francois; Herz, Annette.
According to its principles and standards, organic farming particularly rely on natural processes and functional agro-biodiversity (FAB) to benefit from essential ecosystem services. However, these processes are mostly complex, hardly visible and site-specific, thereby making it difficult to assess and manage on-farm. A European survey has been carried out among organic farmers and emphasizes the variability among countries with a diversity of techniques targeting different functional groups according to farming contexts and farmers’ expectations. The different criteria used by farmers to evaluate FABtechniques efficiency and implementation potential clearly illustrate the difficulty to assess the agroecosystem as a whole.

Disease-resistant vi ne varieties as a tool to minimize the use 01 copper
Provedor de dados: 21
Autores: Basler, Pierre.
Due to the climatic conditions in some viticultural areas of Switzerland, where the annual rainfalilies between 1000 and 2000 mm, the selection of the vine cultivars for organic viticulture encounters very strong restrictions with traditional European varieties. These cir-cumstances necessitate numerous routine sprayings with fungicides. Therefore there is an increasing interest among both, organic and non organic wine growers, to use, to a certain extent, less susceptible vine cultivars. According to the site, the year, the trellising system, the management and the cultivar selected, these vines need much less or even no fungicide treatment. Blind wine tastings show that the sensoric judgment and the acceptance of wines from interspecific cultivars are...

Etude et suivi des problèmes entomologiques en arboriculture dans les conditions de la Suisse latine
Provedor de dados: 21
Le carpocapse est le ravageur-clé en arboriculture.  Le choix limité des produits phytosanitaires contre le carpocapse favorise le développement de résistances envers ces produits.   Les méthode de contrôle biologique (confusion, virus) qui les remplacent sont encore plus chères et plus difficiles à appliquer. De nouvelles méthodes sont développées et de nouveaux produits apparaissent sur le marché.  D'autres ravageurs peuvent occasionnellement créer des problèmes régionaux et doivent être combattus.

Prospecting for new fungicides to control apple scab (Venturia inaequalis) in organic fruit growing
Provedor de dados: 21
Autores: Bengtsson, M.; Heijne, B.; Jong, P.F. de; Jørgensen, H.J.L.; Paaske, K.; Pedersen, H.L.; Trapman, M.; Wulff, E.; Hockenhull, J.
Apple scab (Venturia inaequalis (Cke.) Wint.) causes serious losses in quality and yield of organically as well as conventionally grown apples. Organic apple growers are highly dependent on the use of sulphur, lime sulphur and copper fungicides to control apple scab. Whereas only elemental sulphur is permitted for scab control in organic apple production in Denmark, and in addition lime sulphur in The Netherlands, copper fungicides are used in organic production in many European countries. However, the use of copper fungicides in the EU is now being phased out (EU Council Regulation (EEC) No. 2092/91) and alternative fungicides for control of apple scab and other diseases in other crops are increasingly needed. As part of the EU project REPCO (Replacement...

Autores: Hummel, Edmund; Kleeberg, Hubertus.
In 2000 wurde gegen Kartoffelkäfer ein Pflanzenextrakt aus indischem Neem-Baum - NeemAzal-T/S (1% Azadirachtin) in Deutschland zugelassen. NeemAzal-T/S hat eine effektive Wirkungszeit auf Kartoffelkäfer bis zu 10 Tage nach der Applikation - danach baut sich das Präparat biologisch ab, ohne Rückstände vom Wirkstoff und Formulierung in der Pflanze oder Ernte zu hinterlassen. NeemAzal-T/S gehört zur Gruppe der entwicklungshemmenden Mitteln und zeigt deshalb keine sofortige toxische, sondern eine langsam einsetzende Wirkung.

Hinreichende Wirksamkeit von Pflanzenschutzmitteln im ökologischen Landbau aus Sicht des ökologischen Anbaus
Provedor de dados: 21
Autores: Reiners, Eckhard.
Der Beitrag gibt einen Überblick über die Rolle von Pflanzenschutzmitteln im ökologischen Landbau.   Es wird betont, dass die Pflanzenschutzmittelanwendung häufig nur als ergänzende Maßnahme zu einer Palette kulturtechnischer und vorbeugender Maßnahmen gehört. Dementsprechend reicht es in den meisten Fällen aus, wenn durch die Pflanzenschutzmittelanwendung eine befallsmindernde Wirkung erzielt wird. Eine weitestgehende Eliminierung der Schadorganismen durch eine Einzelmaßnahme ist in der Regel nicht notwendig.

Autores: Döring, T. F.; Hiller, A.; Wehke, S.; Schulte, G.; Broll, G.
Carabids, a species rich arthropod family, potentially contribute  much to biodiversity in agroecosystems, but assessing and  monitoring carabid diversity is costly and time consuming.  Therefore, this study aimed at finding more easily measurable  parameters indicating high carabid diversity within organic and  conventional management systems. Cover and number of weed  species as well as activity density of single carabid species and of  total carabids were investigated as potential indicators of carabid  species richness. The study was carried out near Reckenfeld in  Westphalia on sandy Plaggenesch soils. Three organically and  four conventionally managed fields (cereals and corn) were  investigated at the field margins and in the field centres from...

The scarcity of non-renewable resources such as soils and fertilizers and the consequences of climate change can dramatically influence the food security of future generations. Mutualistic root microorganisms such as plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) can improve plant fitness. We tested the growth response of wheat (Triticum aestivum [L.]), rice (Oriza sativa [L.]) and black gram (Vigna mungo [L.], Hepper) to an inoculation of AMF and PGPR alone or in combination over two years at seven locations in a region extending from the Himalayan foothills to the Indo-Gangetic plain. The AMF applied consisted of a consortium of different strains, the PGPR of two fluorescent Pseudomonas strains (Pseudomonas jessenii,...

Influence of pH and type of myrosinase complex on the products obtained in the myrosinase catalysed hydrolysis of glucosinolates – a MECC study
Provedor de dados: 21
Autores: Bellostas, Natalia; Sørensen, Jens C.; Sørensen, Hilmer.
Environmental conditions, e.g. pH and the presence of Fe2+ are well known factors that influence the product profile of the myrosinase catalysed hydrolysis of glucosinolates. Depending on the plant genera, the species and tissue of origin myrosinase isoenzymes (thioglucohydrolase EC 3.2.1.147) have different characteristics in terms of MW, subunit composition and pI. However, the influence of these parameters on the outcome of glucosinolate hydrolysis has not been traditionally studied, which hinders the full exploitation of the catalytic potential of these enzymes. In the present experiments the effect of myrosinase type on the products obtained in the hydrolysis of glucosibarin was studied by MECC using two B. carinata myrosinase preparations differing...

Development of "Boni-Protect" - a yeast preparation for use in the control of postharvest diseases of apples
Provedor de dados: 21
Autores: Weiss, Armin; Mögel, Gudrun; Kunz, Stefan.
Postharvest pathogens cause major losses in apple production. Gloeosporium album (Pezicula alba) and Gloeosporium perennans (Pezicula malicorticis) are the main pathogens in organic fruit growing. There are several microorganisms with an antagonistic efficency against these fungi. Out of these organisms two yeast isolates have been chosen to develop the plant strengthener Boni-Protect. Boni-Protect reduced the symp-tom development of P. malicorticis, B. cinerea and P. expansum after artificial inoculation of apple wounds. In several field trials preharvest applications of Boni-Protect led to reduced disease development during stor-age.

All the catches were photographed, identifyid and stored. Yellow sticky papers: sticky papers were located in a circle of about 20-60 kilometers from the polarimetric radar in Kumpula. Papers were examined whenever FMI predicted a migration was on its way.  Lygus bugs, flea beetles and bird-cherry aphids were the most common insects on traps in May.  Lygus bugs and flea bettles were probably domestic and bird-cherry aphids migrated.

How to select varieties for organic farming: science and practice
Provedor de dados: 21
Autores: Hoad, S P; Davies, D H K; Topp, C F E.
Selection of cereal varieties suited to organic farming requires a different, but complementary, approach to that used when developing cereals for conventional high input systems. Selection is based on the interaction between a series of desirable plant and crop characteristics, in particular competitive ability against weeds. Certain key characteristics that are generically desirable for organic cereal varieties include: (1 good establishment ability, (2) high tillering ability, (3) increasing plant height, (4) planophile leaf habit, (5) high leaf index and (6) robustnesses in yield performance across sites. Our data strongly suggest that high crop ground cover is the most important feature for creating a highly competitive crop that also has consistency...

Effects of composting manures and other organic wastes on soil processes and pest and disease interactions
Provedor de dados: 21
Autores: Litterick, Audrey; Harrier, L.; Wallace, P.; Watson, C. A.; Wood, M.
Introduction  Composts and manures are of major importance in providing fertility in organic farming systems, since synthetic fertilisers are prohibited. It is understood that composts have radically different nutrient release characteristics to those of uncomposted materials and manures, and it is believed that composting increases the beneficial effects of organic materials on soil health, soil quality, soil fertility and nutrient use efficiency. It has also been shown that some plant pests and diseases are suppressed through the application of composts and compost extracts to soils. There is considerable potential to use a wider range of feedstocks from on and off-farm sources and to improve the composting process and compost/manure application...

Blight-MOP: Development of a systems approach for the management of late blight (caused by Phytophthora infestans) in EU organic potato production
Provedor de dados: 21
Autores: Leifert, C.; Wilcockson, S.J.
Blight-MOP  Late blight (caused by Phytophthora infestans) is the most devastating fungal disease affecting organic (and conventional) potato production in the EU. It kills the foliage and usually results in losses of yield which can be very large when infection is severe and occurs early in the season. The disease may be transmitted to the tubers which become unmarketable and these can lead to complete deterioration of the stored crop if put into storage with healthy tubers. To a great extent, conventional production systems rely upon frequent applications of synthetic fungicides with different modes of action for late blight control, but this is seldom completely successful. However, in organic systems, the availability of chemical fungicides is...

Constraints to the sustainability of a stockless arable rotation
Provedor de dados: 21
Autores: Cormack, W F.
The sustainability of an organic stockless arable rotation on a fertile soil in eastern England was assessed from 1990 to 2005. The good water and nutrient holding characteristics of the silty clay loam soil were well suited to a stockless organic rotation. Fertility-building clover crops were the most difficult to establish, and failed completely in some years despite one or two re-sowings. Crop yields were good, particularly for cereals, with an average for winter wheat of 7 t ha-1. Crop yield did not show any particular trend with time; there was no evidence of either a post conversion adjustment period, or a fall in yield due to declining fertility. High organic crop prices in the 1990s, resulted in significantly higher gross margins than from...

En 2006, une étude réalisée au GRAB dans les mêmes conditions de culture avait montré l'intérêt d'une protection basée sur des lâchers en pépinière du prédateur polyphage Macrolophus caliginosus. L'étude mise en place en 2007 a pour objectif de valider l'intérêt de ce positionnement des lâchers.  Les populations de M. caliginosus se sont bien installées, et leur action, complétée par celle des Dicyphus indigènes est probablement à l'origine du bon état sanitaire de la culture : peu d'aleurodes, pas de thrips, ni pucerons, ni acariens.

Cereal breeding strategies for organic and low-external-input crop production systems
Provedor de dados: 21
Autores: Acikgoz, Prof. Dr. Nazimi; Ilker, Dr. Emre.
Increasing trend in organic farming does not seem to have yet attracted the attention of many plant breeders. On the other side, in every cropping system, for every species, best performing cultivars are needed in each macro-ecology. Considering dif-ferent cropping systems, such as open or glasshouse production, main or second crop alternatives, plant breeders have to focus on the genotype-environment and genotype-input interactions.   Organic farming is in need of tailor-made genotypes for almost every crop. In fact, in the near future the same amount of organic registered cultivars will be needed as the conventional cultivars.  Conducting an immediate single or combined “seed-bed – pot – field test” might be a logical start to de-termine organic...

Suppressive effects of yard waste composts on Pythium spp. and Phytophthora spp. damping-off - a review about several research studies
Provedor de dados: 21
Autores: Bruns, Dr Christian; Hagn, Dr Alexandra; Schloter, Dr Michael; Michel, Dr Kerstin; Ludwig, Prof.Dr. Bernard.
In three long-term studies Yard Waste Composts (YWC) turned out to be sustainable suppressive to Pythium and Phytophthora root rot reducing the disease up to 98%. This was shown under lab and commercial conditions with composts from model and pilot-scale systems. Though suppression was related to microbial activity of the media we could not find a single microbial indicator for suppression over a wide range of samples. High quality YWC of different age showed distinct DNA fingerprints but similar suppressive effects. Thus, still it remains unclear what kind of microbial populations and functions are affecting disease suppression. However, non-destructive near-infrared spectroscopy (NIRS) turned out to predict suppression at least satisfactorily.

Kaolin as a possible treatment against lepidopteran larvae and mites in organic fruit production
Provedor de dados: 21
Autores: Jaastad, G.; Røen, D.; Helgheim, Å-M.; Hovland, B.; Opedal, O.
Few control methods are available in Norwegian organic fruit production that can prevent damage by early  and late larvae. Also phytophagous mites are difficult to control without harming the beneficial mites. Processed  kaolin function by coating trees and thus creating a physical barrier to infestation, impeding movement,  feeding and egg-laying. Kaolin may reduce feeding and movement of over-wintering tortricide larvae  and other larvae that hatch early in spring and have a repellent effect against egg-laying tortricide females in  summer. Kaolin may also have a control effect against mites as it clings to the body and reduce feeding. Trials  with kaolin were conducted in 2003, 2004 and 2005 in plum and apple orchards. Results show that kaolin  reduces...

Yield, pest density, and tomato flavor effects of companion planting in garden-scale studies incorporating tomato, basil, and Brussels sprout
Provedor de dados: 21
Autores: Bomford, Michael K.
Companion planting is a small-scale intercropping practice often associated with organic or biodynamic gardening. Two garden-scale studies tested popular companion planting claims by comparing garden beds devoted entirely to one of three or more test crops (monocultures) to all possible two-crop mixtures (dicultures) of the same species. A third study evaluated effects of planting density and crop ratio in three dicultures using a novel experimental design to create gradients in both factors. All studies incorporated basil (Ocimum basilicum L.), Brussels sprout (Brassica oleracea L.), and tomato (Lycopersicum esculentum Mill.). A preliminary study also included snap bean (Phaseolus vulgaris L.), radish (Raphanus sativus L.) before Brussels sprout, and...

To improve its sustainability, viticulture should increase the provision of ecosystem services to decrease its use of inputs and the resulting environmental impact while maintaining high socio-economic performance. Soil functions in relation with their physical, chemical and biological properties can be regulated by proper soil surface management. Cover crops deliver ecosystem services such as protection of soils, better water infiltration and nitrogen fixation. Yet to avoid trade-off between provision of services and production of grapes, the management of cover crops should adapt to climate variations and to the yield objective. Pest and diseases can be regulated by various technical levers, including the control of the grape vegetative development. The...

Relative Bedeutung des Vorkeimens und der Sortenwahl als ertragssichernde Maßnahmen und zur Vorbeugung von Ertragseinbußen durch Befall mit Phytophthora infestans im ökologischen Kartoffelbau
Provedor de dados: 21
Autores: Möller, Kurt.
Zusammenfassung:    Aus den Ergebnissen kann ganz allgemein geschlossen werden, dass unter den genannten vorbeugenden Maßnahmen das Vorkeimen des Pflanzgutes die stärkste Wirkung auf die Wachstumsdauer der Kartoffelbestände hat. Der mit dem Vorkeimen einhergehende Ertragseffekt ist jedoch sehr stark von den spezifischen Wachstumsbedingungen abhängig. Das Vorkeimen bewirkt signifikante Ertragseffekte bei Sommertrockenheit, das frühere Wachstum und die schnellere Beschattung des Bodens führt zu einer effizienteren Nutzung der Winter- und Frühjahrsniederschläge. Bei ausreichender Wasserversorgung führt das Vorkeimen in der Regel nur auf Standorten mit einer für Öko-Bedingungen hohen N-Versorgung zu höheren Erträgen. Dies kann dadurch erklärt werden, dass je...

Einsatz mikrobiologischer Präparate zur Regulierung der bodenbürtigen Erdbeerkrankheiten Verticillium dahliae und Phytophthora cactorum sowie des Erdbeerblütenstechers
Provedor de dados: 21
Autores: Bisutti, Isabella Linda; Stephan, Dietrich.
Die Erdbeere zählt zu den beliebtesten Obstarten in Deutschland. Allerdings wird eine Ausdehnung des Anbaus -insbesondere des Bio-Erdbeeranbaus - durch hohe Ertragsausfälle aufgrund von Krankheiten und Schädlingen begrenzt. Insbesondere die Krankheitserreger der Rhizomfäule bzw. der Lederbeerenfäule sowie der Verticillium-Welke stellen die wichtigsten bodenbürtigen Krankheitserreger der Erdbeere dar. Inwieweit antagonistische Mikroorganismen gegen diese Bodenpathogene angewendet werden können, wurde am JKI in Darmstadt untersucht.  Aufbauend auf Laborversuchen wurden ad planta Versuche mit dem Bakterium Bacillus amyloliquifaciens FZB42 (RhizoVital® 42 fl.), dem Pilz Trichoderma harzianum T58 (Trichostar®) und dem insektenpathogenen Pilz Metarhizium...

Growing oganic cereals in Northern Ireland - disease and weed problems
Provedor de dados: 21
Autores: Mercer, P C.
The small organic arable sector in N. Ireland could be expanded to provide winter feed for cattle. Spring barley or wheat are likely to be the most suitable crops as they are reported to have fewer weed and disease problems than winter cereals. Trials from 2003 –05 on weed control showed no consistent effect of cultivar, although higher seed rates reduced weed biomass and tended to increase yield, albeit marginally. Trials on disease control showed no synergistic effects of two- or three-way cultivar mixtures over single cultivars, although disease levels were generally low. Particularly in spring barley, results from mixtures tended to be averages of those of individual components. It is suggested that it may be more advantageous and practical to use the...

Mixtures of varieties of spring cereals for weed suppression in organic crop production
Provedor de dados: 21
Autores: Zarina, Livija; Kaczmarek, Sylvia; Melander, Bo.
The suppression of weeds exerted by the crop plays a significant role for weed management in organic crop production. Crop species have different competitive abilities against weeds but also crop varieties vary in their suppression of weeds. Previous studies with varieties of spring cereals have demonstrated marked differences in the suppression of weeds caused by different attributes, such as stem height and leaf area index. However, little is known when different varieties of the same cereal species are mixed in different compositions both in terms of the number of varieties included and the seed rates at which they are established. Some studies have focused on yield and disease aspects but this study aimed to identify and select blends of cultivars of...

Control of seed borne diseasees in organic seed propagation
Provedor de dados: 21
Autores: Borgen, Anders.
Introduction  The key control measure of plant diseases in organic agriculture is crop rotation, mixed cropping and moderate fertilization. A wide range of plant diseases can be controlled or minimized in this way. However, at least one group of plant diseases, the seed borne diseases, cannot. The seed borne diseases are not transmitted through the soil, and crop rotation is therefore an insufficient tool. Mixed cropping is impractical in seed propagation, where seed purity according to the seed legislation is imperative. The fertilization level primarily has an impact on facultative saprophytes, and not on the specialized seed pathogens.    Seed borne diseases were the first plant pathogens to be controlled by pesticides. Heavy metals has been used as...

Während zwei Jahren wurden Versuche, zusammen mit der ACW Wädenswil durchgeführt, um die Chalara- Erregerdichte im Boden vor einer Karottenkultur, mit Biofumigation zu reduzieren. Dabei wurde im Frühjahr vor einer Karottenkultur Brauner Senf angebaut und zur Blüte gemulcht und eingearbeitet. Weder im Boden noch an den Karotten konnte dabei eine Reduktion des Schaderregers beobachtet werden. Die fehlende Wirkung hatte wahrscheinlich folgende Gründe: Die Grünmasseentwicklung des Senfes war zu gering, und die Einarbeitung zu wenig tief.

Spritzbeine: Die nächste Generation

Autores: Koller, Martin.
Auch wenn die meisten Gärtner nicht gerne die Feldspritze anhängen; in vielen Kulturen ist der Erfolg von einem wirksamen Pflanzenschutz abhängig. Mit Ausnahme von NeemAzal T/S wirken alle im Bioanbau erlaubten Behandlungsmittel nur lokal, dass heisst sie wirken nur dort wo sie hingesprüht werden. Viele Versuche zeigen, dass mit einer Applikation unterhalb des Blattdaches, mit sogenannten Droplegs (Spritzbeinen), der Erfolg einer Behandlung verbessert werden kann. Nun sind Spritzbeine entwickelt worden, die deutlich praxisreifer sind, als die bisherigen Prototypen. Schliesslich gilt; wenn schon spritzen, dann richtig.

New tools to manage and assess orchard Functional Agrobiodiversity (FAB)
Provedor de dados: 21
Autores: Sigsgaard, Lene; Warlop, Francois; Pfiffner, Lukas; Herz, Annette.
The EcoOrchard project (2015-18) has produced a handbook on FAB assessment in dialogue with growers and advisors and a technical guideline for FAB orchard management.  Orchards are perennial cultures, and, especially in organic fruit production, it is essential to design and manage orchards in a way which favours predators and parasitoids over pests. Increasing plant biodiversity and habitats in such a way that beneficial organisms are favoured is called Functional Agrobiodiversity (FAB). The value of FAB for reducing pesticide use in fruit production is generally acknowledged, and many organic fruit growers try to increase it in spite of a shortage of information on FAB, economical and technical challenges and lack of situation-specific, detailed advice....

Elicitors and soil management to induce resistance against fungal plant diseases
Provedor de dados: 21
Autores: Tamm, L.; Thürig, B.; Fließbach, A.; Goltlieb, A. E.; Karavani, S.; Cohen, Y.
Air-borne foliar diseases as well as soil-borne diseases can cause substantial losses in agricultural production systems. One of the strategies to overcome production losses caused by plant diseases is the targeted use of disease defence mechanisms that are inherent to plants. In this paper, the potential to enhance the plant’s health status either by inducing resistance through optimized soil management techniques or by foliar application of inducers of resistance is explored on the basis of a literature review and results from laboratory and field experiments. In our studies, the focus was on recent research about the use of dl-ß-aminobutyric acid (BABA) and an aqueous extract of Penicillium chrysogenum (Pen) as elicitors. We conclude that BABA as well...

Autores: András, Jung; Boglárka, Hegedűs; Dóra, Drexler; Michael, Vohland.
Agricultural crops are in different physiological conditions caused by fertilizer, pest and disease incidence, drought or frost. Vegetation response to treatments varies with both the type and the degree of treatment. On the other hand, treatment may cause biochemical changes in the cellular or leaf structure, which have an effect on pigment system or the canopy moisture content.  A variety of factors, including climate, soil, nutrients, phytomass, water content, disease, weeds, insects and more can be measured using ﬁeld spectral radiometers, airborne multispectral, hyperspectral and thermal cameras. High resolution remote sensing provides primary source of information for identifying, classifying, mapping, monitoring of agricultural phenomenon. It can...

Ecological selectivity of pesticides and application methods.
Provedor de dados: 21
Autores: Collier, Rosemary; Jukes, Andrew; Daniel, Claudia; Hommes, Martin.
Abstract: There has been a lot of emphasis over the years on the development and use of pesticides that are specific and/or physiologically selective. This is a property of the chemistry and mode of action of the pesticide and the physiological and biochemical attributes of organisms. However, there is also the potential to make pesticides more selective through their judicious use, based on critical selection, timing, dosage, placement and formulation of pesticides (which are often broad spectrum). This paper discusses approaches to increase the ecological selectivity of pesticides and pesticide application methods, in the context of Integrated Pest Management in Brassica crops. Topics covered include minimisation of the dose applied, controlled release...

Autores: Wohlleben, S.; Bartels, G.
Four field experiments were conducted in 2004 to analyse the efficacy of reduced rates of copper fungicides against Phytophthora infestans (3 x organic and 1 x conventional growing). Copper (Cu-hydroxide, Cu-oxychloride or Cu-octanoate) was sprayed in a weekly routine or according to the decision support system SIMPHYT with total dosages ranging from 0.57 kg/ha to 4.0 kg/ha. The results revealed in almost all treatments a significant reduction of late blight, except for the lowest rates (e.g. 4 x 0.14 kg/ha Cu as Cu-octanoate or 6 x 0.15 kg/ha Cu as Cu-hydroxide). There was a clear dose-response relation between increasing rates of copper and control of late blight in each experiment. Marketable yields varied from 132 dt/ha to 238 dt/ha in organic field...

Autores: Paffrath, Andreas.
Limiting factors in organic potato production are predominantly nitrogen and infesta-tion with late blight disease (Phytophthora infestans). To maintain high yields, organic nitrogen fertilization, presprouting and control of potato late blight with copper-treatments are potential measures. A field trial was conducted in 2005 and 2006 to evaluate which single measure and combination of measures was most likely to achieve the best results. In both years, organic nitrogen fertilization led to an average yield increase of 16%. Tuber presprouting before planting accelerated plant emer-gence, increasing yields by up to 24%. It was the most effective single measure, provided that late blight disease appeared (2005). In absence of infection with late blight,...

Autores: Kleijer, Dr. G.
Winter wheat trials have been carried out from 2002 to 2007 under extensive or organic  conditions. The results of baking quality analyses have been compared for the  same varieties, cultivated under both conditions during the same year. Rheological  analyses generally show lower results for the varieties cultivated under organic conditions  when baking tests result nearly identical in both networks. Wet gluten is an  important baking quality parameter for the users. The percentage of wet gluten is not  correlated with the gluten index, the extensographe energy or the points obtained by  the baking tests. This parameter alone cannot be used for determination of the baking  quality.

Breeding for microbiome-mediated disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Bodenhausen, Natacha; Messmer, Monika.
Plant-associated microbial communities play a crucial role for the expression of various plant traits including disease resistance. Increasing evidence suggests that host genotype influences the composition and function of certain microbial key groups, which, in turn, effects how the plant reacts to environmental stresses. Several studies indicate that modern plant breeding may have selected against plant traits essential for hosting and supporting beneficial microbes. However, they also highlight the presence of an exploitable genetic base for the regulation of the rhizosphere microbiota.  We illustrate the concept of breeding for microbial symbioses with pea (Pisum sativum L.). Firstly, genotypic variation for the efficiency of a mycorrhizal symbiosis is...

Evaluation of grapefruit seed extract as natural fungicide to control apple scab in organic apple growing
Provedor de dados: 21
Autores: Trapman, Marc.
C-pro, an experimental fungicide based on grapefruit seed extract was compared to  copper oxychloride for the control of apple scab in a field trial. Efficacy and possible  phytotoxic effects where accessed. The C-pro formulation was analysed for possible  chemical additives by HPTLC.  C-pro proved tot be more effective in controlling apple scab then the standard rate of  300 gram copper oxychloride per ha, and gave a better leaf quality and less fruit skin  russeting then the standard program of copper oxychloride.  However C-pro contained 6.6 % of the synthetic preservation agent benzethonium  chloride what excludes C-pro from use in organic agriculture.  There is a growing interest in grapefruit seed extract products as well as in other  plant extracts...

Züchtungsmethodische Ansätze zur Erhöhung der Anbaubedeutung der Gelben (Lupinus luteus) und Weißen Lupine (Lupinus albus) im Ökolandbau
Provedor de dados: 21
Autores: Ruge-Wehling, Brigitte; Jansen, Gisela.
Ziel des Vorhabens war es, die Anbauwürdigkeit und Ertragssicherheit von Gelben Lupinen (LUG) und Weißen Lupinen (LUW) zu steigern. Die wissenschaftlichen Arbeitsziele waren (A) Identifizierung von genetischen Ressourcen für Anthraknoseresistenz und Frühzeitigkeit und (B) Charakterisierung von LUG- und LUW-Sorten und Zuchtstämmen hinsichtlich Kornertrag, Rohprotein- und Alkaloidgehalt.  Im dreijährigen Versuch erwies sich die polnische LUG Sorte 'Taper' als sehr resistent und zugleich frühzeitig. Bei LUW wurde diesbezüglich keine Differenzierung beobachtet. Die Vererbungsanalyse der Resistenz in 'Taper' ergab einen monogen-dominanten Erbgang. Zur Entwicklung von Selektionsmarkern für die Resistenz wurden ca. 80 PCR-Markerassays aus verschiedenen...

Alternative Wachstumsregulierung von Pflanzen mittels gesteuerter Vibrationstechnik als Ersatz chemischer Hemmstoffe
Provedor de dados: 21
Autores: Grüneberg, Heiner; Helbig, Diana; Rocksch, Throsten.
Steigende Umweltbelastungen durch Pestizide, in diesem Falle durch chemische Wachstumsregulatoren, erfordern Forschungen zur alternativen Wachstumsregulierung. Der Aktionsplan zur nachhaltigen Anwendung von Pflanzenschutzmitteln des BMEL unterstreicht dieses Absicht. Im durchgeführten Projekt soll eine Wachstumsregulierung (hauptsächlich die Hemmung des Längenwachstums) durch definierte mechanische Reize (Seismomorphogenese) mittels Vibrationen realisiert werden, um einen Verzicht auf synthetische Wuchshemmstoffe möglich zu machen. Die Entwicklung eines anwendertauglichen Vibrationstisches erfolgte zunächst in der Forschungseinrichtung. Anschließend wurden in zwei zertifizierten Bio-Gartenbaubetrieben entsprechende Tische auf ihre Praxiseignung getestet....

Zur Regulierung des Kleinen Fruchtwicklers Grapholita lobarzewskii Ragonot
Provedor de dados: 21
Autores: Kienzle, J.; Buchleither, S.; Scheer, C.; Zebitz, C.P.W.
Several products were tested for their efficacy in control of the apple seed moth (Grapholita lobarzewskii Ragonot). None of them had a good efficacy. With several treatments with Bacillus thuringiensis an efficacy about 50 % could be achieved. An early treatment before egg-laying seem to improve the results. Quassia extract (9 g Quassin/ha/m tree height) gave efficacy about 50-60 % even if treated only once. NeemAzal gave only moderate efficacy (about 40-50 %). Mating disruption method was effective if the populations were not too high when the treatements were started. With high populations there was no sufficient control in the first year of application.

Biologische Bekämpfung von Rhizoctonia solani im ökologischen Anbau mit Hilfe von bakteriellen und pilzlichen Antagonisten
Provedor de dados: 21
Rhizoctonia solani Kühn ist ein weit verbreiteter bodenbürtiger Erreger, der an verschiedenen Kulturen für ökonomisch relevante Ertragsverluste verantwortlich ist. Der Erreger R. solani ist aufgrund seiner sowohl saprophytischen als auch parasitischen Eigenschaften sowie seiner persistenten Dauerorgane (Sklerotien) schwer zu bekämpfen. Seine Fähigkeit auch an Nichtwirtspflanzen seinen Lebenszyklus vollenden zu können, erschwert die Kontrolle über Fruchtfolgen, die insbesondere im organischen Landbau Teil der Bekämpfungsstrategie gegen bodenbürtige Erreger sind. Probleme durch R. solani treten im ökologischen Anbau vor allem an Kartoffeln auf. Derzeit stehen dem ökologischen Anbau keine geeigneten Strategien zur Bekämpfung des Erregers zur Verfügung. Ziel...

Zum Auftreten der Amerikanischen Kirschfruchtfliege in der Nordwestschweiz und im Tessin
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
Eng verwandt mit der Europäischen Kirschfruchtfliege Rhagoletis cerasi sind die beiden amerikanischen Kirschfruchtfliegen R. indifferens und R. cingulata Beide Arten sind morphologisch nicht zu unterscheiden (Foote, 1981). Ein Individuum dieser Artengruppe wurde erstmals in den 80er Jahren im Kanton Tessin in der Schweiz gefangen. Zwischen 1991 und 1993 wurde diese Art dann wiederholt im Süden des Kantons Tessin gefangen (Boller and Mani, 1994). Bisher sind keine grösseren Populationen dieser Art in der Schweiz bekannt (Boller, 2000), was jedoch möglicherweise auf eine zu wenig intensive Überwachung zurückzuführen ist. Ein intensives Überwachungsprogramm im Rheintal (Rheinhessen, Deutschland) konnte zwischen 2002 und 2004 nachweisen, dass diese Art weit...

Management of plant diseases in organic seed potato production
Provedor de dados: 21
The biggest difference between organic and conventional seed potato production is that the use of fungicides against potato late blight and seed borne diseases are forbidden in organic farming. The quarantine diseases such as bacterial ring rots and diseases limited in certified seed, like Erwinia soft rots are a serious threat to organic seed potato production. However the management strategies against these diseases are similar in both organic and conventional production. At the present only one producer in Finland is growing certified organic seed potato. Due to problems in plant protection there has not been enough courage among farmers to specialise organic seed potato production. The aim of current study is to develop crop management strategies for...

Autores: Nielsen, G.C.
For økologiske landmænd med en fremavlskontrakt er det vigtigt at have en fornemmelse af, hvor ofte udsæden kan forventes at blive kasseret pga. udsædsbårne svampe. Nedenfor bringes resultatet af en spørgeskemaundersøgelse hos leverandører af økologisk udsæd i 2005 og de foregående seks år. De laveste kassationsprocenter som følge af udsædsbårne sygdomme blev fundet i havre og rug, hvor 1-2 pct. af partierne blev kasseret. De absolut højeste kassationsprocenter som følge af udsædsbårne sygdomme findes i ærter, hvor i gennemsnit knap halvdelen af partierne (ved en grænse på maks. 20 pct. angrebne frø) blev kasseret i 2003-2005.

Influence of fungicides used in organic orchards on the net-photosynthesis of apple trees
Provedor de dados: 21
Autores: Mittersteiner, Roland; Kelderer, Markus.
Im biologischen Obstbau sind einige wenige Kontaktfungizide (Schwefel-, Kupfer-, Tonerdenpräparate) zur Schorfregulierung zugelassen. Aus der Literatur ist bekannt, dass sich diese Fungizide unterschiedlich auf die Netto-Photosynthese (PN) der Pflanzen auswirken (HOFFMAN 1935, CLORE 1936, MURPHY 1939, SOUTHWICK &amp; CHILDERS 1939). PN spiegelt den Kohlenstoffgewinn abzüglich des Energieverbrauchs durch Atmung wieder. Deshalb hängen Ertrag, Fruchtqualität und Wachstum von Apfelbäumen, neben der Verwertung und Verteilung des Kohlenstoffs innerhalb der Pflanze, auch davon ab, wie viel insgesamt davon aufgenommen wird (LANGE &amp; LENZ 1997, HANSEN 1978).  In dieser Arbeit wurde untersucht, wie sich Behandlungen mit Kupfer, Schwefel, Schwefelkalk und Ulmasud...

Le cumul de pluie reste le principal facteur explicatif du lessivage des produits cupriques étudiés (Héliocuivre et BB RSR Disperss)et donc le seul critère de renouvellement de la protection (hormis naturellement la vitesse de croissance). Les autres critères étudiés, répartition des pluies,intensité  ou délai de 7 jours entre traitement et pluie se révèlent sans effet. Les 5 premiers millimètres de pluie sont ceux générant le plus de pertes, le taux de lessivage diminuant très rapidement au-delà.Environ 40% de la dose initiale reste présent après 50mm de pluie.La perte de cuivre est de nature hyperbolique. Les dynamiques de lessivage ont été modélisées.

Der Ersatz von Kupfer und anderen Pestiziden ist eine der dringlichen Aufgaben der Forschung im biologischen Landbau. Beim direkten Pflanzenschutz stehen fungizid wirkende Substanzen, Biocontrol-Organismen und Pflanzenstärkungsmittel zur Diskussion. Das Konzept der Pflanzenstärkung ist seit langem im biologischen Landbau bekannt. Beispielsweise werden Kompostextrakte, Brennesselextrakte, aber auch kommerzialisierte Produkte aus Reynoutria sachalinensis oder Backpulver eingesetzt.

When resistance to the Mexican isolate of Cydia pomonella Granulovirus (CpGV-M) arose  in several organic orchards in Germany in 2004 and 2005, the future of codling moth  control became a serious concern of organic fruit growing. In 2006, a new virus isolate  from Andermatt Biocontrol AG (Madex Plus) was first tested in two field trials in organic  orchards on codling moth populations resistant against the Mexican isolate of CpGV.  Madex Plus showed a better efficacy on these populations than Madex 3. However, larval  mortality larvae seemed to be somewhat delayed. A very good effect was shown in  population control. The number of larvae in corrugated card board belts was significantly  reduced after treatment with Madex Plus. In addition to these trials,...

Repeated Applications of a Nonpathogenic Streptomyces Strain Enhance Development of Suppressiveness to Potato Common Scab
Provedor de dados: 21
Autores: Hiltunen, L H; Kelloniemi, J; Valkonen, J P T.
Potato scab caused by several Streptomyces spp. is an important disease with no effective methods of control. Suppressiveness against common scab can develop in soil as a result of long-term monoculture and has been associated with nonpathogenic Streptomyces spp. To determine whether the development of scab suppressiveness could be enhanced, the effect of repeated antagonist Streptomyces strain on common scab was investigated in a long-term field trial over 5 years. Streptomyces strain 272 applied annually at planting consistently suppressed development of common scab symptoms. On scab-susceptible potato cultivar Bintje, strain 272 reduced disease severity, on average, by 43 %; whereas, on the scab-tolerant Nicola, the strain reduced both disease incidence...

Impact of water regimes on an experimental community of four  desert arbuscular mycorrhizal fungal (AMF) species,  as affected by the introduction of a non-native AMF species
Provedor de dados: 21
Autores: Symanczik, Sarah; Courty, Pierre-Emmanuel; Boller, Thomas; Wiemken, Andreas; Al-Yahya'ei, Mohamed N.
Field studies have revealed the impact of changing water regimes on the structure of arbuscular mycorrhizal fungal (AMF) communities, but it is not known what happens to the abundance of individual AMF species within the community when the water conditions in the rhizosphere change. The behavior of four AMF species isolated from the Arabian desert (Diversispora aurantia, Diversispora omaniana, Septoglomus africanum, and an undescribed Paraglomus species) was investigated when assembled in microcosms containing Sorghum bicolor as host plant, and treated with various water regimes. Furthermore, the impact of invasion of these assemblages by Rhizophagus irregularis, an AMF species widely used in commercial inocula, was studied. The abundance of each AMF...

Controlling root flies with exclusion fences?
Provedor de dados: 21
Autores: Siekmann, Gitta; Hommes, Martin.
Protecting crops with insect fences is currently being considered as an alternative to row cover netting and synthetic insecticides. Previous studies reported efficacies of such fences with 50-90 % reduction in crop damage by root flies. We conducted trials with a 1.70 m fence over two years to monitor carrot rust fly (Psila rosae) in carrots and cabbage root fly (Delia radicum)  in radish. There was a significant reduction in cabbage root fly damage in fenced plots whereas no such effect could be found with carrot rust fly. The structure of the overhang at the top of the fence and the mobility of this particular species may be important elements to consider in fence design. The length of the overhang also seemed to be important for cabbage root fly (Delia...

Bekämpfung von Microdochium nivale (Schneeschimmel) auf Weizen mit Präparaten auf Pflanzenbasis
Provedor de dados: 21
Autores: Vogelgsang, Dr. Susanne; Bänziger, Irene; Krebs, Heinz; Legro, Robert; Forrer, Dr. Hans-Rudolf.
Snow mold, caused by the fungal pathogen Microdochium nivale, is an important  seed-borne disease of various cereals and fodder plants, leading to reduced stands  after emergence. No agricultural measures are known to prevent snow mold, hence,  direct control measures are needed. For organic agriculture, seed dressing with plantbased  products could be an alternative. In contrast to spray treatments onto the crop,  the formulation and application of plant preparations onto seeds represents a greater  challenge in terms of adhesion, persistence, and lasting efficacy. In the current study,  three plant-based powders applied with two different seed coating materials were  tested for their efficacy against MN of wheat. Both adjuvants demonstrated equally...

Potassium Bicarbonate as a Potential Sulphur Substitute in Protected Organic Cropping
Provedor de dados: 21
Autores: Koller, Martin.
Powdery mildew attacks several important crops in greenhouses (e.g. tomatoes, cucumbers). Compared to other airborne pathogens, such as downy mildews (e.g. Pseudoperonospora cubensis or Phytophthora infestans) or Botrytis, the damage is often not very severe. However, an effective control of powdery mildew with organic fungicides gives the possibility to optimize climate conditions to also prevent downy mildews and gray mold. Sulphur, a well established fungicide, is rated as slightly to very harmful to beneficial organisms (Koppert Biological Systems, 2010) and may have a phytotoxic effect on some crops (e.g. melon). Effects of potassium and sodium bicarbonate (baking soda) against diseases are well known (Horst et al., 1992). In 2008, the European...

Bei mehrjähriger Vermehrung von Wintergerste nach ökologischen Richtlinien muss beim Anbau von anfälligen Sorten mit einem Auftreten von zunehmendem Brandbefall gerechnet werden. Einen Ausweg böte der Anbau von resistenten oder teilresistenten Sorten. Eine verlässliche Testung der Resistenzen gegen Brandkrankheiten benötigt mindestens zwei Prüfzyklen, weshalb bei der Vielzahl neu zugelassener und wegfallender Sorten Kenntnislücken nicht zu vermeiden sind.  Beim Flugbrand zeigten sich die künstlich inokulierte Flugbrand-Prüfrasse und drei weitere Flugbrandherkünfte unterschiedlich virulent. Von 223 Handelssorten und 74 Genbankmustern waren sieben Handelssorten und zwölf Genbankmuster gegenüber der Prüfrasse genetisch resistent. Nur die aktuell zugelassene...

Phytosanitary protocol for the establishment of grapevine certified organic mother plant fields
Provedor de dados: 21
Autores: IYED, Kacem.
In Europe, similarly to propagation material for conventional agriculture, the grapevine organic propagating material must have a certified sanitary status and comply with the requirements of the legislation (EU Reg. 193/68 and Italian D.P.R. N°1164). In organic farming considering the low availability of means to control virus and virus-like disease vector populations and potential virus sources (herbaceous species) it is important to evaluate and prevent all risks of vine reinfection. In three potential suitable fields the following risks have been analysed and evaluated: a) presence of transmissible viruses in spontaneous herbaceous flora (by ELISA and biological assays) and in the surrounding vineyards (by ELISA); b) presence of virus and phytoplasma...

Sund udsæd til korn og bælgsæd
Provedor de dados: 21
Autores: Nielsen, Bent J.
Projektet har dokumenteret, at de fleste grænseværdier generelt også kan anvendes i det økologiske system. Der er dog to vigtige områder, hvor projektet forslår revidering. Det anbefales således at fastholde den vejledende tærskel for frø med ærtesyge på 5% i ærter til modenhed og 10% i ærter til helsæd, men at grænsen udvides til 20%, hvis der bliver mangel på udsæd. Der skal ved mangel på udsæd tages hensyn til, om sorten er anvendelig til helsæd eller ikke. I byg anbefales, at grænseværdierne for bygbladplet baseres på sortens resistensniveau over for sygdommen. Hvis sorten er fuldt modtagelig foreslås en grænseværdi på 5%, mens der i moderat resistente sorter kan accepteres 15% bygbladplet og i resistente sorter helt op til 25% bygbladplet.

At the LVWO Weinsberg in 1998 and 1999 different scab-protecting-strategies were tested at the variety Jonagold. Some examinations were done about fruit-setting depending on additives to sulphur like algae, vitamin E or Kaliumpermanganat.  The conditions of the leaves (damage by scab, intensity of chlorophyll) had a great influence on the number of inflorescences in the following spring. Positive effects by Kaliumpermanganat and Vitamin E were found.  In 1999 was the russetting of the fruits higher than in 1998, all combinations with cupper were more strongly russetted than the control, limesulphur was similiar to the control.

Can ants control plant diseases?
Provedor de dados: 21
Autores: Offenberg, Joachim.
Ants are challenged with disease transmission and microbial hygiene due to a life in densely populated long-lived ant nests. To improve hygiene ants use different ways to reduce microbial growth. They groom their bodies with (i) antimicrobial excretions from their metapleural and poison glands, they (ii) associate with bacterial symbionts capable of producing antibiotics, or they (iv) eat microbial spores. These defenses extend beyond the individual ant, as ants may groom nest mates, food substrates or nesting material. Defenses may even extend beyond the nest and affect mutualistic partners. For example, ants in specialized myrmecophytic ant-plant interactions have been shown to reduce pathogen loads on their host plants. Here we tested if wood ants...

Erfahrungen mit RIMpro in Versuch und Praxis
Provedor de dados: 21
Autores: Tamm, Lucius; Schärer, Hans-Jakob; Denzel, Christoph; Amsler, Thomas.
Die Saison 2005 war ein ausgesprochen anspruchsvolles Jahr für die Bekämpfung von Schorf. In der Primärsaison wurden an 41 Tagen Ascosporenausstoss beobachtet, davon an 20 Tagen Ausstösse mit grösseren Mengen von Ascosporen. Gemäss Modellrechnungen nach RIMpro kam es dadurch zu 8 Ereignissen mit ernstzunehmendem Infektionsrisiko. Zum Vergleich: im Jahr 2004 wurden nur gerade 2-3 derartige Ereignisse verzeichnet. Der Vergleich des gemessenen Ascosporenausstosses mit den Modellrechnungen von RIMpro zeigt, dass die Modellrechnungen relativ gut mit der Realität übereinstimmen. Unsere Erfahrungen im Jahr 2005 zeigen aber, dass für die Kalibrierung des Modells Ascosporenzählungen zu Beginn der Saison unerlässlich sind. Nur wenn die ersten Austösse erfasst...

Pflanzengesundheitliche Bewertung der besonderen Risiken für den ökologischen Landbau durch die Einschleppung und Verbreitung von gebietsfremden Schadorganismen
Provedor de dados: 21
Autores: Müller, Petra; Gärtig, Susanne; Kehlenbeck, Hella.
Der Ökologische Landbau ist aufgrund seiner Produktionsweise stärker als der konventionelle Pflanzenanbau durch die Einschleppung gebietsfremder Arten gefährdet. Die aktuellen Regelungen und Anforderungen zum Schutz des Kulturpflanzenanbaus können kein vergleichbares Schutzniveau für den ökologischen Landbau bewirken, weil diese häufig auf Bekämpfungsmaßnahmen basieren, die im biologischen Anbau nicht angewendet werden können. Vor diesem Hintergrund wurden die derzeit in der EU-Richtlinie 2000/29/EG rund 300 gelisteten Quarantäneschadorganismen bezüglich der von ihnen ausgehenden potentiellen Bedrohung für den ökologischen Landbau geprüft. Dabei zeigten 29 der gelisteten Arten ein besonders hohes Risikopotential für eine Ansiedlung und Schädigung in...

Entwicklung situationsbezogener Strategien zur Vermeidung von Möhrenfliegenschäden auf Praxisbetrieben
Provedor de dados: 21
Autores: Herrmann, Farina; Wedemeyer, Rainer; Liebig, Nadine; Buck, Holger; Hommes, Martin; Saucke, Helmut.
Mit dem Ziel, Möhrenfliegenbefall über eine verbesserte präventive Anbauplanung zu reduzieren, wurden die Anbaukonstellationen von 5 Praxisbetrieben über 3 Jahre hinsichtlich räumlich / zeitlicher Risikofaktoren mit GIS- und der Simulations-Software (SWAT) zur Schädlingsphänologie auf den Befall analysiert.  Bei Möhrenfliegenbefall im Vorjahr war die Entfernung zur Vorjahresfläche der dominierende Risikofaktor. Ähnlich wie bei den ebenfalls im Projekt erprobten Fangstreifen, konzentrierten sich Zuflug und Befall überwiegend auf das nächstgelegene Feld im Umkreis von 10 bis 500m. Dadurch entstanden je nach Anbaukonstellation nutzbare „Nichtbefallslagen“ für entfernter liegende Flächen. Die jeweils empirisch ermittelten kritischen Entfernungen für...

Provedor de dados: 21
Autores: Kunz, Stefan.
In organic apple-growing control agents are necessary to prevent the blossoms being infected by  the fire blight pathogen Erwinia amylovora. Detached apple blossoms were used as an experimental  model to develop preparations based on yeast isolates for use in the control of fire blight. Several  yeast isolates reduced disease incidence in apple blossoms. The efficiency of yeast isolates  was increased by developing a suitable formulation. This yeast preparation exhibited high efficiency  in the control of fire blight in field-trials and will be marketed under the tradename "Blossom-  Protect".

Plan d’actions contre la drosophila suzukii :  fruits à baies
Provedor de dados: 21
L'objet premier du projet est la protection durable des végétaux contre les bioagresseurs invasifs dans les vergers et les vignes dans le Rhin supérieur. Le point fort est la Drosophila suzukii.  Le projet revêt une importance particulière: les petites parcelles des vignobles et des vergers avec leurs structures accompagnantes sont typiques pour la région du Rhin supérieur. Elles abritent une grande diversité d'espèces de flore et faune, mais aussi fournissent des abris et de la nourriture aux espèces invasives. De plus, la région se caractérise par un climat chaud qui convient bien à ces bioagresseurs invasifs qui ne connaissent pas les frontières.   La coopération transfrontalière est donc essentielle pour atteindre les objectifs fixés.  Partenaires:...

Influence of clover species in mixtures with grasses on fatty acid composition of mixtures
Provedor de dados: 21
Autores: Steinshamn, H.; Bleken, M.A.; Langeland, Å.; Thuen, E.
White clover (WC, Trifolium repens L.) or red clover (RC, Trifolium pratense L.) was grown in mixture with grasses. Samples of the mixtures and pure clovers were taken during three cuts, and the fatty acids (FA) compositions were determined. The clover species had no significant effect on the individual FA contents of the leys (g kg-1 dry matter (DM)), nor on the total FA content. Pure clovers had lower content of all individual FA (8.2 vs. 12.4 g kg-1 DM) than mixtures; the contents of all FA decreased with increasing percentage of clover in the mixture, but the decrease was weaker for C18:3n-3 than for the other FA. Although pure WC and RC had similar FA contents, the relative proportions (percentage of total FA content) of C16:0 and C18:3n-3 differed;...

Autores: Renaud, E.N.C; Lammerts van Bueren, E.T.; Myers, J. R; Paulo, M.J.; Eeuwijk, F.A.; Zhu, N.; Juvik, J.A.
Organic agriculture requires cultivars that can adapt to organic crop management systems without the use of synthetic pesticides as well as genotypes with improved nutritional value. The aim of this study encompassing 16 experiments was to compare 23 broccoli cultivars for the content of phytochemicals associated with health promotion grown under organic and conventional management in spring and fall plantings in two broccoli growing regions in the US (Oregon and Maine). The phytochemicals quantified included: glucosinolates (glucoraphanin, glucobrassicin, neoglucobrassin), tocopherols (d-, c-, a-tocopherol) and carotenoids (lutein, zeaxanthin, b-carotene). For glucoraphanin (17.5%) and lutein (13%), genotype was the major source of total variation; for...

Abwehr von Wühlmausschäden im ökologischen Obstbau
Provedor de dados: 21
Wühlmausschäden gehören zu den am schwierigsten lösbaren Pflanzenschutzproblemen im ökologischen Obstbau. Nach einer Umfrage waren im Jahr 2002 79 % der deutschen Apfelanbaubetriebe von solchen Schäden betroffen. Auf 80 % der Flächen war die Schermaus (A. terrestris) der Hauptschadensverursacher. 61 % der Obstbauern sahen einen hohen Bedarf an der Entwicklung neuer Präventiv- und Bekämpfungsmaßnahmen.  Um die Einwanderung von Wühlmäusen in Obstbauflächen zu verhindern, wurde ein mechanisches Barrieresystem entwickelt und an je einem Standort in Baden-Württemberg und Rheinland-Pfalz getestet. An jedem Standort wurden zwei ca. 0,7 ha große Parzellen mit Barrieren aus Drahtgitter (Maschenweite 10 mm) bzw. Polyolefin-Folie umgeben. Zwei ungeschützte...

Effect of organic, low-input and conventional production systems on yield and diseases in winter barley
Provedor de dados: 21
Autores: Cooper, J. M.; Schmidt, C. S.; Lueck, L.; Shotton, P. N.; Turnbull, C.; Leifert, C.
The effect of organic, low-input and conventional management practices on barley yield and disease incidence was assessed in field trials over two years. Conventional fertility management (based on mineral fertiliser applications) and conventional crop protection (based on chemosynthetic pesticides) significantly increased the yield of winter barley as compared to organic fertility and crop protection regimes. Severity of leaf blotch (Rhynchosporium secalis) was highest under organic fertility and crop protection management and was correlated inversely with yield. For mildew (Erysiphe graminis), an interaction between fertility management and crop protection was detected. Conventional crop protection reduced severity of the disease, only under conventional...

Plant protection is still a burning issue in organic apple production. Insufficient strategies lead to minor quali-ties and immense profit cuts. To thwart these problems and to support organic apple production a program has been started to test a new cultivation system for apple farming. Preconditions for the profitability of the new method are a high yield of premium quality apples comparable to those reached in conventional farming. Main components of the new cultivation system are a foil canopy to prevent fungal infections and lateral net-tings for protection against animal pests and to allow the application of beneficial organisms. To meet the top claims of organic production no chemical plant protection is performed and EU regulations are regarded....

In humid regions and organic production of potatoes, late blight poses a special challenge for farmers. The only effective treatment against it is copper, which is strictly  regulated by EU and national organic regulation bodies. “Bio-Austria” as an Austrian one, allows for example only 2 kg copper ha-1 year-1. The Institute for Organic Farming  at AREC Raumberg-Gumpenstein carried out two field trials in 2010 and 2012 with two alternative treatments in comparison to copper: Myco-Sin and an extract of field horsetail (Equisetum arvense). The field trials confirmed the use of copper as best protection of the leaves against late blight with the highest tuber yield, showing a significant difference to all other treatments.

Heterogeneity of protected crop colonization by beneficial insects: role of crop management and landscape context
Provedor de dados: 21
Autores: Aviron, Stéphanie; Perraudin, M.; Redondo, S.; Varennes, Y-D.; Lefèvre, Amélie.
Enhancing insect pest control by their natural enemies is considered as a promising crop protection strategy in organic vegetable production systems. In Mediterranean areas, native natural enemies such as mirid bugs (Heteroptera: Miridae) settle spontaneously in protected vegetable crops and can play an important rolefor pest regulation, which remains however very heterogeneous from field to field and hardly predictable. The present study is part of the project REGABRI, which aims at identifying key factors of colonization of organic and conventional protected tomato crops by mirid bugs in Roussillon area. A first survey in 2010-2011 on 34 crops showed that mirids abundances in crops vary according to management practices and landscape features in the...

Alternative, non-animal based nutrient sources, for organic plant raising OF0308
Provedor de dados: 21
Autores: Unspecified,.
Organic plant raising has been investigated under two previous government funded projects (OF0109 &amp; OF0144) (1, 2) and it was shown in this research that organic ‘transplants’ could be produced for a range of crop species (3, 4, 6, 7).  However, some species were easier to produce than others and one of the limiting factors was the availability of suitable nutrient sources, especially for supplementary feeding.   The use of animal based nutrient sources in organic plant raising has always been considered far from ideal and there are now moves within the EU to ban all animal bi-products in organic plant raising.  This work aimed to identify suitable non-animal based nutrient sources to be used as base nutrients for growing media and as supplementary...

A non-chemical method for monitoring adult olive weevil populations in Tadla-Azilal plain in Morocco
Provedor de dados: 21
Autores: EL JIATI, Abdelazize.
The olive weevil becomes one of the major olive pests in Tadla-Azilal in Morocco. The chemical control is expensive and of low efficiency. Its application at night complicates the task for olive growers. An alternative non-chemical method has been developed using polyester fiber as a trap. It has a high efficiency, low cost and might be advised to organic olive farmers.

Results from a Research Project about foliar fertilizers in organic fruit-growing
Provedor de dados: 21
Autores: Belz, J.; Pfeiffer, B.
The intention of this research project, which was supported within the "Bundesprogramm Ökologischer  Landbau", was to investigate in 2003 the situation on organic apple farms of nutrition of  leaves and fruits of the variety 'Topaz' and 'Elstar'. The contents of N, P, K, Ca and Mg were determined  in the leaves in April, June and August, micronutrients like Fe, Mn, Zn, B and Cu in April and  August. The number of flower-clusters per tree, the fruit-setting and the yield were investigated.  There were great differences between the orchards, the yield per tree varied between 3 and 24 kg,  depending from the age and height of the trees. Field trials were done to proof the effect of the foliar  fertilizers Vinasse, Biokal, Phytoamin, Wuxal Ascofol and Humulus....

Integration of fertility management, cultivar selection and alternative spray treatments to optimize control of foliar diseases of greenhouse grown tomatoes
Provedor de dados: 21
Autores: Dafermos, N.G.; Kasselaki, A.M.; Malathrakis, N.E.; Leifert, C.
Powdery mildew caused by Leveillula taurica (Lev.) Arn. is one of the most serious foliar diseases of greenhouse and open field tomato. The disease is currently controlled with the use of organic fungicides and sulphur, the latter being the only product permitted in organic crops. The aim of this study was to investigate the potential of controlling the disease by integrating: a) hybrids of low susceptibility to the disease, b) organic fertilisers (chitin) and c) alternative spray treatments. Some of the combinations of the above factors were highly effective in decreasing the percentage of disease severity. Specifically the combination of the hybrid of low susceptibility with the addition of chitin in the substrate and the spray treatment...

Perennial survival of common bunt (Tilletia tritici) in soil under modern farming practice
Provedor de dados: 21
Autores: Borgen, Anders.
Three years of field trials in Denmark have shown that common bunt (Tilletia tritici) is able to infect wheat in crop rotations with several intercrops between susceptible crops. This contradicts most previous literature which concluded that common bunt is a seed-borne pathogen only able to infect through the soil in cases where wheat is grown in two consecutive years. It is argued that the reason for this change in pathogenicity can be explained by a change in farming practice

Vinterhvede
Provedor de dados: 21
Autores: Hansen, Jesper.
Som det fremgår af foregående afsnit, er det stadig ikke så spændende at dyrke vinterhvede, som det har været. Merprisen for brødhvede er efter vores opfattelse for lav i forhold til ulemperne, der er forbundet med dyrkningen. Den største del af hveden afsættes da også til foder. Har man en god forfrugt og/eller gødning til rådighed, er vinterhvede da også konkurrencedygtig når det gælder afsætning til foder. Dette gælder især for den gode jord.

Autores: Markkula, Irmeli; Ojanen, Hannu; Tiilikkala, Kari; Raiskio, Sakari; Pylkkö, Pirkko; Koistinen, Jarmo; Leskinen, Matti; Ooperi, Sini.
In this migration event we could observe large insects migrating high in the atmosphere nearly inside precipitation at the cloud base or between precipitative cells. On the other hand, daytime migrants seemed to fill most of the rain free areas. The accuracy of forecasted rain areas is probably never good enough to predict where and when rain would cause the insects to land, and dispersion model may have difficulties in predicting the migration through partially rainy weather. In addition, the highest levels of infestation may occur at rain areas that form barriers for the migrants.

Vorhersage der Backeignung von Weizen (Triticum aestivum L.) anhand struktureller Unterschiede in der Glutenin-Komposition
Provedor de dados: 21
Autores: Linnemann, Dr. Ludger.
To dissect the most important determinant of wheat bread-making quality, gluten protein-types from 128 flours of organically grown German wheat varieties Bussard and Orestis were investigated by quantitative HPLC and SDS-PAGE procedures using protein standards. Both varieties exhibit great differences in gluten strength (&gt; 34 %) at two locations and between two years determined by SDS-sedimentation volume (SDS-SV), a measure of bread-making quality. Unexpectedly, the results showed that neither concentrations of gliadin, gluten, HMW-glutenin or glutenin could explain the observed variation in SDS-SV even if protein concentrations were equal. In the case of glutenin this was found to be due to a low glutenin recovery resulting from a partial insolubility...

Potato is affected by numerous diseases. Among those diseases, late blight (Phytophthora infestans) and rhizoctonia (Rhizoctonia solani) have a strong economic impact. Organic farming doesn’t have efficient protection products to control those diseases and to guarantee yield and production quality. Furthermore, we observe that organic food chain propose the same cultivars as the traditional food chain and those cultivars are generally susceptible to late blight. Regarding to the trials managed to propose new cultivars to Swiss cultivars recommendation list, there are numerous new cultivars with interesting resistance profile. Among 141 cultivars tested, 30 could be proposed to the organic food chain. Indeed, those cultivars are less susceptible to late...

Rhagoletis cerasi: Oviposition reduction effects of oil products
Provedor de dados: 21
Autores: Daniel, Claudia.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. Methods to control it are limited and alternatives are needed.Observations of cherry fruit flies suggest that females exert much effort to penetrate cherries at color change stage (from green to yellow) for oviposition. Therefore, the question arose as to whether a physical barrier on the fruit surface could reduce oviposition. The effects of different commercial horticultural oil products on R. cerasi oviposition were evaluated in a series of laboratory, semi-field and field experiments. In the laboratory experiments, the rate of successful oviposition on fruits treated with 0.25% v/v of the rapeseed oil product Telmion was significantly reduced by...

Identification and quantification of ‘Candidatus Phytoplasma pyri’ in declining trees of a Swiss cider pear orchard after incision treatment at the stem base
Provedor de dados: 21
Autores: Toenshoff, E. R.; Brunner, H.; Tamm, L.; Schärer, H.-J.; Oberhänsli, T.
Candidatus Orchards of 30 to &gt;100 years old fruit trees used for cider production are endangered by an accumulation of abiotic and biotic stress factors. Among biotic stress factors, diseases such as pear decline (PD) caused by the bacterial pathogen ' Phytoplasma ' contributes to a weakening and reduced life time of affected trees. Since direct treatment of this disease is not possible, approaches have gained attention, which might lead to an increased resilience against this pathogen, such as incisions of the cambium at the graft union at the stem base. Six 35 years old pear trees () of a Swiss cider production orchard, all affected by mild decline were chosen for this study. Four out of them were treated with 2-4 incisions per tree in February 2016....

Biologisk bekämpning: genetisk analys av mekanismer
Provedor de dados: 21
Fluorescerande pseudomonader är en grupp bakterier som är vanligt förekommande i jord och på olika växtdelar. De är ofta nyttiga för växter genom deras förmåga att skydda växten mot sjukdomar och/eller stimulera tillväxt och skörd. I detta projekt har vi arbetat med en fluorescerande pseudomonad som är den aktiva beståndsdelen i ett biologiskt fröbehandlingspreparat, Cedomon™, som marknadsförs av BioAgri AB (Uppsala), och som har effekt framför allt mot fröburna svampsjukdomar i stråsäd. Celler av denna bakterie som appliceras på ett frös utsida har förmågan att skydda den framväxande plantan mot svampsmitta som redan finns närvarande inne i fröet. Viktiga frågeställningar för projektet har varit: hur lyckas bakterierna åstadkomma denna s.k. biologiska...

Which carabid species benefit from organic agriculture? - a review of comparative studies in winter cereals from Germany and Switzerland
Provedor de dados: 21
Autores: Döring, Thomas; Kromp, Bernhard.
Data of comparative studies about carabid beetles in organically and conventionally managed winter cereal fields of central Europe, using the pitfall trapping method, were collected from the literature and unpublished data sources and were then pooled and analysed. According to an index, which was designed to calculate how much a species benefits from organic management, Carabus auratus turned out to benefit most. Some Amara species (A. familiaris, A. similata and A. aenea) as well as Pseudoophonus rufipes and Harpalus affinis also showed high index values. When analysing the traits of the carabids, the habitat preference was the most important variable for the differentiation of organic and conventional management. The stronger the preference for open...

IS LEAF LITTER REMOVAL MORE EFFICIENT THAN LEAF LITTER SHREDDING TO CONTROL APPLE SCAB? A FIRST ANSWER IN A COMMERCIAL ORGANIC ORCHARD
Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Gomez, Christelle; Gros, Christophe; Asencio, Pedro; de le Vallee, Damien; Brun, Laurent.
In organic apple orchards, sanitation practices are a keystone of a sustainable scab management. Because the suppression of the inoculum by leaf litter removal could be a promising practice, we carried out an experiment to assess the interest of leaf removal versus leaf shredding on disease development and fruit damages. For one of the two cultivars studied, we showed that leaf litter removal can significantly decrease scab damages on fruit and leaf in comparison to leaf shredding.

Användning av feromoner för varning och bekämpning av vinbärsskottmal i svarta vinbär
Provedor de dados: 21
Vinbärsskottmal (Lampronia capitella) uppträder som skadedjur i svarta vinbärsodlingar. Artens larver förstör under våren skottknopparna och vid höga populationstätheter kan skadorna medföra stora skördeförluster. Vid ekologisk vinbärsodling är arten mycket svår att bekämpa med nu tillgängliga medel och metoder. Bekämpning med hjälp av artens sexualferomon enligt förvirringsmetoden kan vara ett sätt att öka odlingssäkerheten för ekologiska odlare. Feromonerna kan användas även av konventionella odlare för att fastställa om och när ett bekämpningsbehov finns. För detta andamål behövs kunskap om samband mellan fällfångst och larvangrepp och kunskap om honornas äggläggningsperiod. Vinbärsskottmalens feromon har nyligen identifierats och kan användas direkt i...

Wildflower companion plants increase pest parasitation and yield in cabbage fields: Experimental demonstration and call for caution
Provedor de dados: 21
Autores: Balmer, Oliver; Géneau, Céline E.; Belz, Elodie; Weishaupt, Bettina; Förderer, Gerda; Moos, Sebastian; Ditner, Nadine; Juric, Ivan; Luka, Henryk.
Monocultures typical of intensive agriculture offer ideal conditions to specialized herbivores while depriving their natural enemies of habitat and nutritional resources. The resulting release of herbivores from both bottom-up and top-down control causes pest outbreaks in economically important crops. Boosting locally occurring natural enemy populations through species-specific habitat management to restore natural herbivore control has been much advocated but remains rarely tested in the field. Here, we investigated whether adding specifically selected flowering plants to monocultures increases parasitation rates of herbivores and crop yield. We performed replicated field experiments in 2 years and found that adding cornflowers (Centaurea cyanus) into...

Autores: Kühn, Birka Falk.
Twentyfive apple varieties were evaluated for Apple scab (Venturia inaqualis), Nectria  canker (Nectria galligena) and Powdery mildew (Podosphaera leucotricha) for 4 to 7 years.  The trees were grown unsprayed. The weather conditions at the experimental orchard  normally results in high infections of apple scab and low infections of powdery mildew.  Infections of Apple scab is often seen also in scab resistant varieties. Williams Pride,  Katinka and Katrina (scabresistant varieties) were the only varieties not showing scab in  the experimental period. The two scabresistant varieties Angold and Produkta (varieties  having a poor fruit quality) was unsusceptible to Nectria canker.

Autores: Trivedi, Mahendra Kumar; Branton, Alice; Trivedi, Dahryn; Nayak, Gopal.
Among the oilseeds grown around the world, mustard is one of the important crop worldwide due to its wide adaptability and high yielding capacity. Owing to the importance of its utilities as condiment, cooking oil and some medical aids, the demand for its seed production is too high. The present study was carried out to evaluate the impact of Mr. Trivedi’s biofield energy treatment on mustard (Brassica juncea) for its growth-germination of seedling, glutathione (GSH) content in leaves, indole acetic acid (IAA) content in shoots and roots and DNA polymorphism by random amplified polymorphic-DNA (RAPD). The sample of B. juncea was divided into two groups. One group was remained as untreated and coded as control, while the other group was subjected to Mr....

Autores: Asser-Kaiser, Sabine; Fritsch, Eva; Undorf-Spahn, Karin; Kienzle, Jutta; Eberle, Karolin; Gund, Nadine; Reineke, Annette; Zebitz, Claus; Heckel, David; Jehle, Johannes.
Insect-specific baculoviruses are increasingly used as biocontrol agents of lepidopteran pests in agriculture and forestry, and thy have been previously regarded as robust to resistance development by the insects. However, in more than a dozen cases of field resistance of codling moth Cydia pomonella to commercially applied C. pomonella granulovirus (CpGV) in German orchards, resistance ratios exceed 1000. The rapid emergence of resistance is facilitated by sex-linkage and concentration dependant dominance of the major resistance gene and genetic uniformity of the virus. When the gene is fixed, resistance levels approach 100.000-fold. Our findings highlight the need for development of resistance management strategies for baculoviruses.  (C)2007, American...

How expensive is vole damage?
Provedor de dados: 21
Autores: Walther, B.; Fülling, O.; Malevez, J.; Pelz, H.-J.
Vole species, especially Arvicola terrestris and Microtus arvalis cause significant economical damage in organic pomiculture by gnawing the root system of trees. The importance of voles as pest organisms is well known. Nevertheless, the estimation of financial loss caused by voles is difficult for German fruit growers. We conducted a survey among organic fruit growers to get data on kind and amount of annual damage. Using the available publications and official statistics we calculated economical values of organic apple trees for different types of orchard processing and tree ages. Furthermore we calculated the number of trees lost due to voles in one year.

Evaluation of the users value of salts against apple scab and powdery mildew for fruit production
Provedor de dados: 21
Autores: Creemers, P.; Van Laer, S.; Van Mechelen, A.; Vorstermans, B.; Hauke, K.
The research was aimed at finding anti resistance strategies for Integrated fruit growing.  As the salts tested may be approvable for organic farming, the trial results are also of  value for the development of scab an mildew control strategies for organic fruit growing. As  new fungicides are mainly unisite action fungicides, the problem of fungicide resistance  development is becoming more important every year. Combining chemical fungicides,  which is the best anti-resistance strategy, is not always possible or recommended in the  case when the number of available chemical fungicides are limited or a reduction in  fungicide use is asked for. Therefore the use of salts as an anti-resistance strategy was  looked upon. The salts evaluated were K(HCO3),...

Single and multiple applications of pyrethrin and kaolin were tested at different dates after apple harvesting in autumn 2002 when sexuales of the rosy apple aphid were present. Repeated applications of Surround WP in autumn significantly reduced the number of females in autumn and, consequently, the number of hatched fundatrices in spring. Single kaolin treatments were less effective. Unexpectedly, neither single nor multiple applications of the contact insecticide...

Die untersuchten morphologischen Merkmale weisen insgesamt eine niedrigere Heritabilität und eine geringe Korrelation mit Kornertrag auf. Dies weist darauf hin, dass sich diese Merkmale nur bedingt als Selektionsmerkmal und zur Sortenbeschreibung eignen. Aber auch wenn nur ein geringer positiver Zusammenhang mit dem Kornertrag erkennbar ist, kann sich z.B. ein höherer Bodenbedeckungsgrad auf lange Frist die Menge der Unkrautsamen im Boden verringern. Der positive Zusammenhang von Pflanzenhöhe und Ertrag ist teilweise durch eine bessere Gesundheit hoher Pflanzen zu erklären.

Use of genetic resources and partial resistances for apple breeding
Provedor de dados: 21
Autores: Kellehals, Markus; Duffy, Brion.
Modern apple breeding strategies are mainly considering the most advanced selections and culti-vars as parents. This tends to lead to a narrowed genetic basis. The introgression of traditional va-rieties and accessions of the gene pool is often feared due to undesirable characteristics that might be incorporated. However, there is scope for considering a wider genetic basis in apple breeding to support sustainable fruit production systems. The focus at Agroscope Changins-Wädenswil (ACW)  is put on high fruit quality combined with low susceptibility to scab (Venturia inaequalis), fire blight (Erwinia amylovora), and powdery mildew (Podosphaera leucotricha). The Swiss scab and fire blight resistance research programs are focused on developing and applying...

Here, large-scale untargeted LC-MS-based metabolomics was used to compare the composition of white cabbage from organic and conventional agriculture, measuring 1,600 compounds. Cabbage was sampled in 2 years from one conventional and two organic farming systems in a rigidly controlled long-term field trial in Denmark. Using Orthogonal Projection to Latent Structures-Discriminant Analysis (OPLS-DA), we found that the production system leaves a significant (p = 0.013) imprint in the white cabbage metabolome that is retained between production years. We externally validated this finding by predicting the production...

Agronomic aspects of strip intercropping lettuce with alyssum for biological control of aphids
Provedor de dados: 21
Autores: Brennan, Eric B.
Organic lettuce growers in California typically use insectary strips of alyssum (Lobularia maritima (L.) Desv.) to attract hoverflies (Syrphidae) that provide biological control of aphids. A two year study with transplanted organic romaine lettuce in Salinas, California investigated agronomic aspects of lettuce monoculture and lettuce-alyssum strip intercropping on beds in replacement intercropping treatments where alyssum transplants replaced 2 to 8% of the lettuce transplants, and in additive intercropping treatments where alyssum transplants were added to the standard lettuce density without displacing lettuce transplants. Alyssum and lettuce dry matter (DM) were determined at lettuce maturity. Alyssum transplants produced less shoot DM in the additive...

Does fruit-tree architecture manipulation affect the development of pests and pathogens? A case study in an organic apple orchard
Provedor de dados: 21
Autores: SIMON, S.; LAURI, P.E.; BRUN, L.; DEFRANCE, H.; SAUPHANOR, B.
Centrifugal training, based on the extinction procedure, is an innovative type of apple tree training recently used in French apple orchards. The thinning cut of fruiting spurs along the trunk and on the proximal and underside parts of the fruiting branches modifies the within-tree leaf density and light environment, which is likely to affect the development of some apple pests and pathogens. In this study, the development of the most serious foliar pests (aphids, mites) and disease (apple scab) was assessed over 3 years in an organic apple orchard with two training systems: the centrifugal training (CT) system, and the original Solaxe (OS) system, using a bent axis with no removal of fruiting spurs, as a control. Infestation levels were significantly...

Reduzierung des Phytophthora-Primärbefalls durch eine Kupferbeizung unter den besonderen Bedingungen des Ökologischen Kartoffelanbaus
Provedor de dados: 21
Autores: Benker, M.; Zellner, M.; Kleinhenz, B.
Im ökologischen Kartoffelanbau stellt der Primärbefall ein großes Problem dar, weil er mit Kupferspritzungen nur schwer zu kontrollieren ist und schnell zum vorzeitigen Ausbruch von Sekundärbefall führen kann. Nach ergiebigen Niederschlägen und hoher Bodenfeuchte kann der Erreger Phytophthora infestans entweder von der latent infizierten Pflanzknolle im Stängel nach oben wachsen oder auf der Oberfläche der Pflanzknolle sporulieren. Unter für den Erreger optimalen Witterungsbedingungen können beide Infektionswege einen Primärbefall am Stängel auslösen.

Complex interplay of future climate levels of CO2, ozone and temperature on susceptibility to fungal diseases in barley
Provedor de dados: 21
Autores: Mikkelsen, B. L.; Jørgensen, R. B.; Lyngkjær, M. F.
Barley (Hordeum vulgare) was grown in different climatic environments with elevated CO2 (700 vs 385 ppm), O3 (60/90 vs 20 ppb) and temperature (24/19 vs 19/12°C day/night) as single factors and in combinations, to evaluate the impact of these climatic factors on photosynthesis and susceptibility to powdery mildew and spot blotch disease. No significant increase in net CO2 assimilation rate was observed in barley grown under elevated CO2 at ambient temperature. However, this rate was positively stimulated under elevated temperature together with a slightly higher potential quantum efficiency of PSII, both at ambient and elevated CO2, suggesting that photosynthesis was not limited by CO2 at ambient temperature. When growing under elevated temperature or O3,...

Residues of copper and sulphur on fruits from organic orchards
Provedor de dados: 21
Autores: Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
Copper und sulphur compounds are listed in annex 2b of the EC regulation 2091/92 and  are used in organic orchards to control scab, mildew and sooty blotch also during summer  time. In Italy, copper compounds have a waiting period from 20 days between last  treatment and harvest, for sulphur compounds it differs and can reach until 30 days for  lime sulphur. The trials carried out showed that using the recommended low dosages for  copper and lime sulphur it should not be a problem to reduce these waiting periods. The  residues remained clearly under the legal values, also when the samples where collected  the same day of the treatment.

Arthropod pest management in organic crops
Provedor de dados: 21
Autores: Zehnder, Geoff; Gurr, Geoff M.; Kühne, Stefan; Wade, Mark R.; Wratten, Steve D.; Wyss, Eric.
Burgeoning consumer interest in organically produced foods has made organic farming one of the fastest growing segments of agriculture. This growth has not been supported adequately by rigorous research to address challenges such as arthropod pest management. The research that has been conducted, however, is complemented by research in aspects of conventional agriculture that may have applicability in organic systems, as well as by research in underpinning ﬁelds such as applied ecology. This article synthesizes the available literature in relation to a conceptual model of arthropod pest management strategies suitable for organic systems. The present work uses the four phases of the model to review the strategies in an agroecological context and provides a...

Capacity of Deep Rooted Species to Take Up Water and  Nutrients from Deep Soil Layers
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Rasmussen, Camilla Ruø; Thorup-Kristensen, Kristensen.
Introduction  Agricultural cropping systems generally have a limited use of water and nutrients from the soil below 1m depth. However, several plant species have much deeper root systems, and if included in cropping systems, these would allow for exploitation of otherwise unused resources from deep soil layers. In a unique facility consisting of 12, 4m high ‘root towers’ we examined the root development and root activity in different soil layers of different biannual/perennial plant species.    Methods  Four plant species lucerne (Medicago sativa), rosinweed (Silphium integrifolium), intermediate wheatgrass (Thinopyrum intermedium), and dyers voad (Isatis tinctoria) were grown in soil in large rhizotrons (root towers) (4m×1.2m×0.6 m). Root growth was...

Negative effects of low developmental temperatures on aphid predation by Orius majusculus (Heteroptera: Anthocoridae)
Provedor de dados: 21
Autores: Helgadóttir, Friða.
Biological control agents (BCA) are often mass reared at conditions very different from those at which they have to provide their service, especially if they are to be used under field conditions. It has been suggested that biocontrol efficiency might be enhanced by acclimating the BCA under near-field conditions for some time before release (beneficial acclimation hypothesis), and some studies (e.g. with ladybirds) have supported this idea. We reared Orius majusculus, a commercially available BCA, at three temperatures (12, 16 and 20 °C) throughout the whole development. The predation capacity for rosy apple aphids (Dysaphis plantaginea) of females from each of these treatments was tested at the same temperatures (12, 16 and 20 °C). Additionally, we...

The Nafferton factorial systems comparison (NFSC) experiments facilitate the investigation of effects of, and interaction between, three production system components - a) rotational position, b) fertility and c) crop protection management - in organic, conventional and low-input crop management systems. This paper presents first results on pesticide and growth regulator residues observed over a period of two years. Residues were only detected for three (Chlormequat, Chlorothalonil and Aldicarb) of the 28 pesticides used in the experiments. As expected, residue levels were affected by the crop protection practices, but significant effects of fertility management practices were also detected. This indicates that the human health risks associated with...

Rolling of grains to prevent winter kill damage
Provedor de dados: 21
Autores: Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
The pressure of the roller stimulates not only the forma¬tion of roots and improves access to water, but stimulates also the tiller of the grain increasing its stability and thus reducing the risk of falling over.  Practical recommendation  • Rolling requires dry soil in order to prevent the soil from sticking to the roller and ripping out the plants (especially when using smooth rollers).  • The corrugated roller must not damage the plants too much. Take special care when using sharp-edged rollers.  • Every mechanical interference puts the plants under stress. For this reason, it is advised to go at a maximum rolling speed of 5 km/h.  Notes  • Even in densely sown or strongly fertilized spelt crops, the rolling is recommended. It weakens the main shoot...

Acting against common bunt: exploration of various control methods
Provedor de dados: 21
Autores: Fontaine, Laurence; Robin, N.; Bruyère, J.; du CHEYRON, P.
Common bunt (Tilletia caries, Tilletia foetida) is a fungal disease with a large ability to spread. Consequences may be rejection of grains for sale or even a large decrease of yield. Different trials were carried out in organic farming in a research project (funded by the French Ministry of Agriculture between 2008 and 2011) to achieve a better control of common bunt. Results confirm that the resistance of wheat cultivars is a factor to consider. Despite most varieties currently cultivated in organic farming are sensitive to common bunt, some cultivars appeared to be resistant to the races tested. Concerning seed treatment, no product is available for organic farming and 100% efficient; but several solutions have been identified. Only one product is...

Autores: Schmitt, Annegret; Scherf, Andrea; Schuster, Christina; Gärber, Ute; Marx, Peggy; Idczak, Elke; Rupp, Jochen; Leinhos, Gabriele; Konstantinidou-Doltsinis†, Stavroula.
A raw extract of licorice (Glycyrrhiza glabra) was tested against downy mildew in vegetables under semi-commercial conditions. In two greenhouse trials in cucumber, efficacies of ca. 70% were achieved (3% extract concentration) in either 7 or 10-11 day application intervals. Under open field conditions, weekly treatments resulted in ca. 2 week retardation of disease. In open field trials in lettuce, efficacies after weekly application of 5% G. glabra extract were variable, depending on disease pressure. In contrast, on lettuce seedlings in climate chambers, the extract reduced disease incidence of Bremia lactucae by 66 to 100%. In onion, applications of the extract at 6% concentration failed to control Peronospora destructor, despite of high efficacies...

Wie kommen Giftspuren in den Biowein? Und vor allem: Wie lassen sie sich vermeiden, welche Ritzen muss man stopfen? Das Amt für Lebensmittelkontrolle von vier Ostschweizer Kantonen und das FiBL legen einen neuen Untersuchungsbericht vor.

Organic potatoes, reduced tillage and mulch in temperate climates
Provedor de dados: 21
Autores: Finckh, Maria R.; Bruns, Christian; Bacanovic, Jelena; Junge, Stephan; Schmidt, Jan Henrik.
The experiments with mulching were done in a systems approach comparing potatoes as they are typically produced in Germany with ploughing to a system of non-inversion tillage combined with mulch. As the plots are integrated in two long-term experiments comparing ploughed versus minimum tillage it was not possible to integrate a mulched ploughed treatment or a non-mulched non-inversion tillage due to restrictions in plot size. We tested the effects of mulching in a ploughed system in 2015. There was no late blight but good erosion control (Pict.5) and yields were increased through mulching. Compost effects on the system were so far not clearly visible. It will most likely take several more years of regular applications to start seeing changes in system...

Monitoring of total contents of copper in organically and  conventionally managed soils. Part 1: Study plan and  preliminary sampling of copper and other anthropogenic  induced heavy metal contents in vineyard soils
Provedor de dados: 21
Autores: Riepert, Frank; Steindl, Anna; Eibach, Rudolf; Maixner, Michael; Reichmuth, Christoph; Strassemeyer, Jörn; Strumpf, Thomas.
The project aims to develop a survey designed for the representative assessment of copper contents in vineyard soils. The method development for the sampling of adequate monitoring areas is based on a preliminary survey of load distribution as well as on exposure assessment on selected areas of some typical vinery sites in Rheinland-Pfalz, differently managed and with different use history. Additionally to the sampling of selected areas, which reflects the spectrum of the load situation in viticulture, chemical quantitative analysis of soil samples collected from areas of known mode of cultivation and history followed by biological standard tests will be conducted.  Obtained findings will serve for further method development, for preselection of adequate...

Kløvertretthet - et problem i økologisk engdyrking?
Provedor de dados: 21
Autores: Serikstad, Grete Lene; de Boer, Anne; Magnusson, Christer.
Kløvertretthet er en fellesbetegnelse på sykdom og misvekst hos kløver. Det kan være flere årsaker til kløvertretthet, blant annet angrep av ulike nematoder og råtesopper. Intensiv engdyrking med kløver og bruk av kløver som underkultur og grønngjødsel i andre kulturer i økologisk drift vil gi et stort innslag av kløver i vekstskiftet, noe som vil øke faren for problemer med kløvertretthet. Det fins lite kunnskap om omfanget av problemene i Norge.  I prosjektet er det utført en enkel kartlegging av status for situasjonen i Sverige, Danmark og Nederland. I Sverige legges det vekt på rotråte som årsak til problemene. I Danmark og Nederland anbefales vekstskifte for å unngå avlingsskader på grunn av nematoder. For å kartlegge situasjonen i Norge ble jord og...

Regulierung von Schadschnecken im Erwerbsgemüsebau
Provedor de dados: 21
Im Labor untersuchten wir die artspezifische Wirksamkeit der Nematodenart Phasmarhabditis hermaphrodita (Handelsprodukt "Bioslug-Schneckennematoden", resp. "NemaSlug"). Dabei bestätigte sich, dass diese Nematoden gegenüber ausgewachsenen Spanischen Wegschnecken (Arion lusitanicus) ungenügend wirken; frisch geschlüpfte Spanische Wegschnecken sind jedoch sehr empfindlich gegenüber den Nematoden. 1999 versuchten wir, die Spanische Wegschnecke früh im Frühjahr zu bekämpfen, wenn sie noch klein ist. Diese Strategie war allerdings nicht erfolgreich, da die Spanische Wegschnecke grössere Wanderungen macht, und somit zu wenig lange im Kontakt mit den Nematoden ist, um infiziert zu werden.

Efficacy of products allowed in organic olive farming against Bactrocera oleae (Gmel.)
Provedor de dados: 21
Autores: Iannotta, Nino; Belfiore, Tiziana; Noce, Maria Elena; Perri, Luigi; Scalercio, Stefano.
In organic olive farming one of the most problems is how to control the olive fly. The present study has been performed in two different Calabrian olive areas in order to test some active molecules allowed by regulation concerning organic farming. The tested compounds were Rotenone, Azadiractin, Copper, Kaolin and Propolis. The results showed that, at harvesting time (end of October), the lowest infestation has been registered on the trees treated with Propolis and Kaolin in both investigated fields. The obtained results display that the restraining of the active infestation of Bactrocera oleae within limits of 20%, compatible with a quality production, turns to be possible also in Southern olive areas.

The aim of this work is to evaluate the impact of oil cake amendments (argan, neem, castor cake and ground castor) on control of Meloidogyne spp., soil fertility, and the growth and yield of cucumber grown under greenhouse in south-western Morocco. The results show that oil cakes induce a reduction in gall formation, soil nematodes density, root rot infestation, and an improvement of plant height and yield as compared to the control. Argan cake improved yield by 112% compared to the control. Generally, argan cake gave better results compared to the other treatments. In pots experiment on melon, maximum suppression (100%) of root knots and soil larvae population were found with argan, castor cake and ground argan shoot; while neem cake was less effective....

Effect of Compost versus Animal Manure Fertilization on Crop Development, Yield and Nitrogen Residue in the Organic Cultivation of Potatoes
Provedor de dados: 21
Autores: Willekens, Koen; De Vliegher, Alex; Vandecasteele, Bart; Carlier, Lucien.
Organic farmers in Flanders use manure from extensive conventional livestock systems due to a lack of animal manure from organic producers. The research question was if on-farm prepared compost mainly consisting of vegetal residues can be a good alternative. A long-term fertilization trial with a 4-year crop rotation of maize - potatoes - spring barley - red clover is carried out on two fields with a time difference of one year. The fertilization treatments are on-farm prepared compost, applied as a single dose and a double dose, farmyard manure, slurry and slurry combined with composted municipal waste. This paper concerns the experimental results of the potato crop in 2006 and 2007. The nitrate content of the plant juice was monitored and the potato...

The majority of crops grown in the UK are host to single or multiple insect pests that feed on the growing plant at some stage of their life cycle. Insect pest is not strictly correct terminology because the pests come from a wide range of families or groups, from Coleoptera (beetles), Diptera (true flies), Lepidoptera (butterflies and moths), Molluscs (slugs and snails) and Nematodes.  This technical sheet lists major and minor pests, provides a simple key for identifying soil pests, lists requirements for effective cultural control of pests and lists sources of further information.

Effect of mechanical soil treatment in blueberry orchards
Provedor de dados: 21
Autores: Benduhn, Bastian; Maxin, Peter; Pfeiffer, Barbara.
From June 2004 onwards a trial was conducted on a blueberry farm in the Lüneburg  Heath, Northern Germany, in which methods of mechanical soil cultivation were compared  with mulching. The aim was to determine how far the mechanical methods and equipment  established for soil management in viniculture and pomiculture can be adapted to  blueberry cultivation, and can be improved. The results showed a clear advantage of the  methods based on mulch technology in the shape of increased yields. Whilst the  mechanical treatments provided acceptable weed control, they cannot be recommended  for routine use at present because of strong yield reductions associated with damage to  the shallow root system of highbush blueberry shrubs.

Verbesserung der Jugendentwicklung von Sojabohnen durch Priming und Saatgutbeigaben
Provedor de dados: 21
Aufgrund der in Mitteleuropa vergleichsweise kühlen Temperaturen zur Aussaat von Sojabohnen sind sowohl das Auflaufen als auch die Jugendentwicklung der Sojapflanzen insgesamt häufig verzögert. Diese Verzögerungen können die jungen Pflanzen schwächen, den Befall mit bodenbürtigen Schaderregern erhöhen und die Konkurrenzkraft der Sojapflanzen gegenüber Unkräutern erheblich mindern. Aus diesem Grund sind Maßnahmen, die ein zügiges und möglichst gleichmäßiges Auflaufen sowie ein kräftiges Jugendwachstum fördern, entscheidend für einen erfolgreichen Sojaanbau unter hiesigen Bedingungen. Wissenschaftliche Untersuchungen haben gezeigt, dass Saatbeigaben von bestimmten Mikroorganismen (Rhizobakterien und Mykorrhiza-Pilze) oder von sojaeigenen isoflavonoiden...

Most horticultural crops are attacked by more than one insect pest. As broad-spectrum chemical control options  are becoming increasingly restricted, there is a need to develop novel control methods. Semiochemical attractants  are available for three important horticultural pests, strawberry blossom weevil, Anthonomus rubi Herbst  (Coleoptera: Curculionidae), European tarnished plant bug, Lygus rugulipennis Poppius (Hemiptera: Miridae) and  raspberry beetle, Byturus tomentosus deGeer (Coleoptera: Byturidae). Traps targeting more than one pest species  would be more practical and economical for both monitoring and mass trapping than traps for single-species. In this study we aimed to (1) improve the effectiveness of existing traps for insect pests in...

Investigations on the efficacy of different products for the control of Stephanitis pyri  in an organic pear orchard during the two-year period 2004-'05
Provedor de dados: 21
Autores: Vergnani, S; Caruso, S.
The results of two trials, carried out  respectively in 2004 and 2005, against Stephanitis pyri in an organic pear orchard are reported. Different formulations of the following active substances were tested:  pyrethrum + PPBO, rotenone, rotenone + pyrethrum + PPBO, azadirachtin,  Beauveria bassiana strain ATCC 74040, Marsiglia and potassium soap; and quassia wood. The  pyrethrum + PPBO- and rotenone-based formulated products showed good efficacy, when applied against neonate larvae. A good efficacy was also observed with the azadirachtin-based formulation, but the product may have phytotoxic effects on pear, and therefore its use is not recommended. The  B. bassiana-based product showed partial efficacy in controlling the target pest, while the efficacy of...

Experiences in Transplanting Wood Ants into Plantations for Integrated Pest Management
Provedor de dados: 21
Autores: Nielsen, J.S.; Nielsen, M.G.; Offenberg, J.
Ants can function efficiently as biocontrol agents in open field horticulture. Temperate wood ants can control forest pests, including species damaging forest regeneration plots and fruit plantations. Thus, they possess potential as biocontrol agents in open field horticulture, if they can persist in these systems. Here we present observations on activity and survival of wood ants transplanted from forests into different types of plantations. Mound fragments were transplanted into a conifer seedling plot, an organic and a conventional Christmas tree plantation, and into an organic apple plantation. Colonies survived at least one year in all types of plantations. In some cases, however, ants moved to new locations or migrated between mound fragments,...

Organic seed treatment to control common bunt (Tilletia tritici) in wheat
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt caused by the fungus Tilletia tritici (syn. T.caries) is one of the most devastating plant diseases in wheat. In conventional agriculture the disease is controlled exclusively by fungicide seed treatment, but in organic farming these fungicides are not accepted. Previous studies in India have shown that seed treatment with plant extracts of Canabis sativa, Eucalyptus globulus, Thuja sinensis and Datura stramonium was fully effective against the disease under field conditions. Later, in vitro studies have shown that also germination of spores of the Karnal bunt pathogen (Neovossia indica) could be prevented by these plant extracts. The experiment was repeated in Denmark with extracts from the same species grown in Denmark, which has climate...

Using weeds to reduce pest insect numbers in organic vegetable crops - a desk study (OF0329)
Provedor de dados: 21
Autores: Grundy, Dr Andrea.
At present, weeds and pest insects are two of the major constraints to the production of high quality organic vegetable crops, primarily because the range of control measures available to UK growers is extremely limited. Several studies have shown that the numbers of pest insects found on crop plants are reduced considerably when the crops are allowed to become weedy. However, if weeds are not removed by a certain stage of crop growth, they start to compete with the crop plants and yield begins to decline. Warwick HRI already has models that are used independently to predict both the onset of weed competition and the timing of pest insect attacks. However, in practice, growers have to manage weeds and pest insects at the same time and hence the decisions...

Integrated control of slug damage in organic vegetable crops- OF 0158
Provedor de dados: 21
Autores: Glen, David.
Slugs are important pests of a wide range of organic vegetable crops, which are high quality products, desired by consumers. Slug problems are especially acute in comparison to conventional vegetable production because use of chemical control measures is prohibited. The purpose of this project is to provide organic vegetable growers with effective integrated pest management techniques for control of slug damage. The project builds on the results of MAFF Project No. OF0137 (September 1996 to March 1999), which demonstrated that biological control using slug-parasitic nematodes (Phasmarhabditis hermaphrodita) can give effective and long-lasting control of slug damage to organic vegetable grown in polytunnels in autumn and early spring.

Effect of autumn application of urea on saprotrophic fungi in off-season leaf litter of sour cherry and evaluation of fungal isolates to reduce primary inoculum of Blumeriella jaapii
Provedor de dados: 21
Autores: Bengtsson, M.; Green, H.; Leroul, N.; Pedersen, H.L.; Hockenhull, J.
The effect of autumn application of urea on the activity and composition of saprotrophic fungi associated with sour cherry (Prunus cerasus) leaf litter infected with the leaf spot pathogen, Blumeriella jaapii, was studied under orchard conditions from the time of leaf fall to the release of ascospores, the following spring. The ability of treatment of infected leaves post leaf fall with urea or with inoculum of selected fungal strains to reduce primary inoculum (ascospores and winter conidia) of B. jaapii in spring was evaluated. Fungal activity was measured enzymatically by quantifying -N-acetylglycosaminidase and fungal composition and frequency were evaluated following isolation at low temperature of mycelia embedded in leaf particles.

The effect of potato variety mixtures on epidemics of late blight in relation to plot size and level of resistance
Provedor de dados: 21
Autores: PHILLIPS, S L; SHAW, M W; WOLFE, M S.
Potatoes of a number of varieties of contrasting levels of resistance were planted in pure or mixed stands in four experiments over 3 years. Three experiments compared the late blight severity and progress in mixtures with that in pure stands. Disease on susceptible or moderately resistant varieties typical of those in commercial use was similar in mixtures and pure stands. In 2 of 3 years, there were slight reductions on cv. Sante, which is moderately susceptible, in mixture with cv. Cara, which is moderately resistant. Cara was unaffected by this mixture. Mixtures of an immune or near-immune partner with Cara or Sante substantially reduced disease on the latter.  The effect of the size of plots of individual varieties or mixtures on blight severity was...

Plants for predators - a participatory experiment
Provedor de dados: 21
Autores: Sievwright, H C; Sutton, G L; Rosenfeld, A.
Encouraging natural enemies by growing attractant plants is a highly effective method of pest control in organic systems. However, it is important to establish which plants are most effective at attracting benefi cial insects. Experiments were carried out by 179 HDRA members, who grew four plant species (Coriander, Corn Marigold, Fennel and Phacelia) in their gardens and allotments. Over the course of the growing season, assessments were made on the growth and flowering of the plants and the presence of four key groups of beneficial insect (ladybirds, hoverflies, lacewings and parasitic wasps). Phacelia established quickly and its long flowering period meant it attracted insects throughout the summer. However, Phacelia was only the most attractive plant at...

Regulierung des Falschen Mehltaus an Salat – Neue Lösungsansätze durch Erprobung feldresistenter Sorten aus biologisch-dynamischer Zucht in Kombination mit verschiedenen anbautechnischen und pflanzenstärkenden Maßnahmen
Provedor de dados: 21
Der Falsche Mehltaus (Bremia ssp.) stellt seit Jahren durch erhebliche Qualitätsmängel und empfindliche Ertragseinbußen eine große Gefährdung des ökologischen Salatanbaus dar. Trotz der konsequenten Umsetzung vorbeugender Maßnahmen und der Etablierung resistenter Sorten gibt es keine wirksamen langfristigen Lösungsansätze. Der Grund dafür liegt u.a. in der hohen Variabilität und Agressivität des Erregers, der es durch die Bildung ständig neuer Rassen schafft, neue monogene Sortenresistenzen (vertikale Resistenz) innerhalb kürzester Zeit zu überwinden. Aber auch anbautechnische Zwänge führen zu einer Förderung dieses Erregers (z.B. lange Blattnässedauer durch Einsatz von Kulturschutznetzen zur Schädlingsabwehr oder Beregnung).

Innovative strategies for the control of apple scab (Venturia inaequalis [Cke.] Wint.) in organic apple production
Provedor de dados: 21
Autores: Jamar, Laurent.
The aim of this thesis, conducted over six growing seasons (20032008), is to define new measures for reducing the use of fungicides and in particular, copper fungicides, for the control of apple scab (V. inaequalis) in organic apple production. Special emphasis is put on primary scab infection control during spring season. An original approach is proposed for defining a specific spray timing involving spraying during the infection processes, especially before fungal penetration, determined by the RIMpro software warning system. This ‘during-infection’ spray strategy allows reducing from 30 to 50% the amount of fungicide usually used for effective apple scab control, on high scab-susceptible cultivars. The field study shows that six alternative products...

The main role of the Spanish group within BIO-INCROP is to investigate novel approaches to the fight against soil-borne pathogens causing growth diseases in organic citrus production. These new strategies range from the use of biologically-active commercial products to management options to improve soil biological activity and diversity, together with techniques for soil disinfection suited for organic cropping.  Several assays are currently under way to evaluate in detail such strategies. Most of the work is being performed in a field trial set in an old farm sited at Gandía (Valencia),  wherein citrus have been cultivated for more than a century. Many Phytophtora attacks have been recorded in the last decades, and intensive farming has also led to a very...

Autores: Wolfe, M S; Hinchsliffe, K E; Clarke, S M; Jones, H; Haigh, Z.
Genetically diverse Composite Cross Populations (CCPs) may be useful in environmentally variable low-input systems as an alternative to pure line varieties. They are formed by hybridising lines with diverse evolutionary origins, bulking the F1 progeny, and allowing natural selection of the progeny in successive crop environments. CCPs derived from 10 high yielding parents (YCCPs), 12 high quality parents (QCCPs), or all 22 parents (YQCCPs), were grown at four sites (2 organic, 2 conventional) in the UK; they are currently (2006) in F5. The YCCPs out yielded the QCCPs, which had better quality characteristics. Although the CCPs performed within the range of the parents, the values obtained were often better than the mean of the parents. Some population...

Functional biodiversity to improve pest control in organic cropping systems
Provedor de dados: 21
Autores: Pfiffner, Lukas; Schärer, Hans-Jakob; Luka, Henryk.
A sustainable use of functional agrobiodiversity (FAB) providing habitats with suitable floral resources is needed to conserve and improve pest control by natural enemies in organic cropping and other low-input systems. We present an overview on our activities identifying appropriate flowering plants in relation to the antagonists-pest complex and quantifying benefits and limits in lab- and field tests. We have focussed on the control of apple-aphids and cabbage lepidopterean pests in two organic cropping systems. We can show that tailoring the flowering strips to the needs of specific natural enemies within a cropping system is a key issue for successful application of FAB. We found plants as Fagopyrum esculentum, Centaurea cyanus and Vicia sativa...

Manipulating within-orchard and adjacent habitats to provide better pest control in organic orchards. Some elements for modulating “orchard tree-pest-natural enemy” relationships
Provedor de dados: 21
Autores: SIMON, S.; SAUPHANOR, B.; DEFRANCE, H.; LAURI, P.E.
The control of pests in organic orchards cannot solely rely on the use of direct control methods. The effect of manipulating the habitat of orchard pests and natural enemies through tree architecture and the increase of plant diversity has been investigated in an experimental organic apple orchard and in a pear orchard, in order to provide information about the potential benefits of these cultural practices. Tree training affected the development of the most detrimental pests of apple trees, and the centrifugal training system globally provided better aphid (Dysaphis plantaginea) and mite (Panonychus ulmi) control than the more classical Solaxe system, whereas codling moth (Cydia pomonella) was favoured compared to Solaxe. The study of an experimental...

Contributions of EU-project REPCO to apple scab control
Provedor de dados: 21
Autores: Köhl, Jürgen; Heijne, Bart; Hockenhull, John; Lindhard Pedersen, Hanne; Trapmann, Marc; Eiben, Ute; Tamm, Lucius.
The objective of REPCO is to contribute to the replacement of copper fungicides in organic agriculture by new measures for control of downy mildew (Plasmopara viticola) in grapevine and scab (Venturia inaequalis) in apple. Both major European organic crops strongly depend on copper fungicides. Permitted amounts will be reduced stepwise during the following years (Council Regulation (EEC) 2092/91, Annex II) to avoid environmental risks. In European countries where copper fungicides are already out of use, production of organic apples suffers severe economical problems because of insufficient scab control.   Potentiators of resistance, organically based fungicides and biocontrol agents are screened and evaluated in apple. Effects of crop management practices...

Organic seed treatment to control common bunt (Tilletia tritici) in wheat
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt caused by the fungus Tilletia tritici (syn. T.caries) is one of the most devastating plant diseases in wheat. In conventional agriculture the disease is controlled exclusively by fungicide seed treatment, but in organic farming these fungicides are not accepted. Previous studies in India have shown that seed treatment with plant extracts of Canabis sativa, Eucalyptus globulus, Thuja sinensis and Datura stramonium was fully effective against the disease under field conditions. Later, in vitro studies have shown that also germination of spores of the Karnal bunt pathogen (Neovossia indica) could be prevented by these plant extracts. The experiment was repeated in Denmark with extracts from the same species grown in Denmark, which has climate...

Autores: Daniel, Claudia; Hommes, Martin; Koller, Martin.
Growers of organic Brassica vegetables and oilseed rape face the same potentially severe plant protection problems as their colleagues in conventional or integrated pest management systems.Management strategies in organic systems rely on preventive measures (crop rotation, crop isolation,soil management, host plant resistance, farm/field location; manipulate timing of planting or harvest; intercropping, mulching), use of functional agro-biodiversity (reduction of pest by enhancing natural enemies), release of biocontrol agents and a few approved pesticides of biological and mineral origin, as well as mating disruption or the use of anti-insect nets (Zehnder et al., 2007). The methods used in organic might also be applicable in IPM systems. However, several...

Cadmium uptake by cocoa trees in agroforestry and monoculture  systems under conventional and organic management
Provedor de dados: 21
Autores: Gramlich, A.; Tandy, S.; Andres, C.; Chincheros Paniagua, J.; Armengot, L.; Schneider, M.; Schulin, R.
Cadmium(Cd) uptake by cocoa has recently attracted attention, after the European Union (EU) decided to establish values for tolerable Cd concentrations in cocoa products. Bean Cd concentrations from some cocoa provenances, especially from Latin America, were found to exceed these values. Cadmium uptake by cocoa is expected not only to depend on a variety of soil factors, but also on plant and management factors. In this study, we investigated the influence of different production systems on Cd uptake by cocoa in a long-term field trial in the Alto Beni Region of Bolivia,where cocoa trees are grown inmonocultures and in agroforestry systems, both under organic and conventional management. Leaf, fruits and roots of two cultivars were sampled fromeach...

Autores: Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
The aim of this study was to investigate possible interactions between a preventive and a curativ method  (combination of one pre and one post-emergence weed harrowing). We estimated the damages by weed harrowing in four pure varieties of spring barley, and analysed if there were differences in resistance and tolerance to weed harrowing between the varieties. As organic growing conditions are characterised by greater differences in nutrient levels, we further examined if there was any interactions between harrowing resistance and tolerance of the varieties and two nutrient level. Tolerance to weed harrowing was measured as an immediate effect (Resistance=how much of the plant is covered with soil after weed harrowing), a short-term effect (growth rate...

Bekämpfung von Drosophila suzukii in Reben: Versuchsbericht 2014
Provedor de dados: 21
Autores: Daniel, Claudia; Matray, Silvia; Gallati, Philip.
Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa eingeschleppt und verursacht seitdem z.T. massive Ertragsausfälle. Sie befällt alle Weichobstarten, wie z.B. Beeren, Kirschen, Zwetschgen und Trauben. Auch viele wilde Pflanzen, wie z.B. Holunder und Schneeball dienen als Wirtspflanzen. Der Hauptschaden entsteht durch den Larvenfrass an den Früchten. Da der Generationszyklus sehr kurz ist und daher mehrere Generationen parallel auftreten, kommt es zu einem starken Befallsdruck im Spätsommer und Herbst. Da Weinreben länger hängen als z.B. Beeren und die Lese erst im Herbst stattfindet, findet ein besonders starker Einflug statt. In diesem Tastversuch wurden fünf verschiedene Mittel und Mittelkombinationen gegen D.suzukii...

Plant protection in an organic crop rotation experiment for grain production
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Askegaard, Margrethe; Olesen, Jørgen E.
The plant protection carried out in the Danish crop rotation experiment is described. These measures can be quite different in the different systems. While mechanical weed control can be carried out in systems without catch crops, it is not possible to do so in systems with catch crops without affecting the establishment of the catch crop.   The occurrence of weeds, pests and diseases is recorded, and the results are described. Since the results are only from the two first years of the experiments, it is not possible to conclude anything about the crop rotations as such. There are however differences related to the other experimental treatments in the experiment: the presence or absence of catch crops and manure. Only in very few cases are the differences...

The best application technique and application data for the treatments with Quassia extract against  the apple sawfly Hoplocampa testudinea Klug were tested. The spraying solution was distributed  best on the receptacle of the blossom – the place where the sawfly larvae feed before the enter the  blossom – when the treatment was effecttuated at fading blossom with a high amount of water  (about 500 l/ha/mTh). The addition of T/S forte, a wetting agent, could also improve the efficacy of  Quassia treatments in a lower dose. Thus, it is recommended to apply in fading blossom with addition  of T/S forte and high amounts of water to obtain the best effect.

Integration of different control measures to maximise disease control of Plasmopara viticola in Italian organic viticulture
Provedor de dados: 21
Autores: Dagostin, Silvia; Ferrari, Alessandro; Pertot, Ilaria.
In organic viticulture so far only copper can assure a good control of the disease but its use will be limited by the European community to 6 kg/ha/year from 2006, because of its accumulation in soil. Efficacy against Plasmopara viticola on grapes of 17 new and 10 alternatives to traditional copper for-mulations were compared respectively in glasshouse and experimental field, in Italy in 2005. Four products (plant extract 1, Bion® 50 WG, Tecnobiol and Elot-vis®) controlled P. viticola artificial infections under greenhouse conditions, but only one (Bion®) con-firmed its efficacy under vineyard condition. None of the other tested products showed a comparable control.

Autores: Alkemade, Joris; Arncken, Christine; Voegele, Ralf T.; Finckh, Maria R.; Hohmann, Pierre; Messmer, Monika.
Durch ihren hohen Proteingehalt und tiefen Nährstoffbedarf ist die Weisse Lupine (Lupinus albus) eine nachhaltige europäische Alternative zum gegenwärtig massiven Sojaimport für Futter und Nahrung. Der Lupinenanbau ist jedoch durch die Brennfleckenkrankheit Anthraknose, verursacht durch den saatgutbürtigen Pilz Colletotrichum lupini, stark eingeschränkt. Schon ein geringer Saatgutbefall kann zum totalen Ertragsausfall führen. Für einen erfolgreichen Anbau der Weissen Lupine ist es daher wichtig, Resistenzquellen zu finden.

Sowing time affects the abundance of pests and weeds in winter rye
Provedor de dados: 21
Autores: Huusela-Veistola, Erja; Jalli, Heikki; Salonen, Jukka; Pahkala, Katri; Laine, Antti.
Selection of an appropriate sowing time for some winter rye (Secale cereale) cultivars could reduce the need for crop protection measures. In this study the occurrence and status of pests and weeds in relation to sowing time and growth habit of winter rye was studied in southern Finland. This was done using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye was severely affected by pests (Oscinella frit, Mayetiola destructor) and weeds, whereas postponing sowing for two weeks after the recommended sowing time in late August resulted in considerably less damage and the optimal establishment of crop stands. The German hybrid varieties Picasso and Esprit produced more tillers m-2 in autumn...

Identification of Heterotrophic Zinc Mobilization Processes  among Bacterial Strains Isolated from Wheat Rhizosphere  (Triticum aestivum L.)
Provedor de dados: 21
Autores: Costerousse, Benjamin; Schönholzer-Mauclaire, Laurie; Frossard, Emmanuel; Thonar, Cécile.
Soil and plant inoculation with heterotrophic zinc-solubilizing bacteria (ZSB) is considered a promising approach for increasing zinc (Zn) phytoavailability and enhancing crop growth and nutritional quality. Nevertheless, it is necessary to understand the underlying bacterial solubilization processes to predict their repeatability in inoculation strategies. Acidification via gluconic acid production remains the most reported process. In this study, wheat rhizosphere soil serial dilutions were plated on several solid microbiological media supplemented with scarcely soluble Zn oxide (ZnO), and 115 putative Zn-solubilizing isolates were directly detected based on the formation of solubilization halos around the colonies. Eight strains were selected based on...

Translocation of imidacloprid from coated rape (Brassica napa) seeds to nectar and pollen
Provedor de dados: 21
Autores: Eggen, T.; Odenmarck, S.R.; Løes, A.-K.
Bees and other pollinating insects contribute significantly to the world’s production of edible crops. Bees and bumblebees are threatened by modern agricultural practices like monocropping, destruction of natural habitats and pesticide use. Organic farming practice avoids the pesticides, but should also actively support the living conditions for pollinating insects, e.g. by maintaining flowering strips and trees. A recent ban on imidacloprid as rapeseed coating in Norway may encourage research in alternative ways of protecting rapeseed against ground flees (Phyllotreta spp.). Such studies may be beneficial also for organic rape growers.

Lutte contre le mildiou de la laitue (Bremia lactucae) sous abri froid : compte-rendu d'essai 2011
Provedor de dados: 21
Autores: Lambion, Jérôme; Gomes, Liliane; Brenner , Johanna.
Le mildiou de la laitue (Bremia lactucae) est la maladie la plus redoutée sur cette espèce,notamment en culture biologique d’hiver sous abris. En Provence, les dégâts sont très importants, parfois dès la pépinière, et entraînent de fortes pertes financières. Cette situation est due à deux facteurs principaux : d’une part au contournement récurrent des résistances génétiques par de nouvelles souches de Bremia (28 races déterminées à ce jour), et d’autre part à la faiblesse des méthodes de lutte biologique possibles contre ce champignon (notamment la faible efficacité des traitements à base de cuivre). Cet essai s’inscrit dans le cadre d’un programme CASDAR porté par l’ITAB visant à tester des extraits de plantes.

Mechanical In-Row Weed Control in Transplanted and Direct-Sown Bulb Onions
Provedor de dados: 21
Autores: Ascard, Johan; Fogelberg, Fredrik.
Different strategies for mechanical in-row weed control were evaluated in direct-sown and transplanted bulb onions (Allium cepa) in terms of in-row weeds, labour requirements for hand weeding and marketable yield. Transplanted onions generally performed much better than direct sown onions. The best strategies in transplanted onions decreased the hand weeding time by 70% and increased marketable yield by 96% compared with the best strategies in direct-sown onions.      In transplanted onions, one weed harrowing and three in-row cultivations with torsion weeders reduced in-row weed numbers by 85%, reduced hand weeding time by 73%, and caused no yield reduction compared with the normal strategy of one weed harrowing and ordinary inter-row cultivation.

En nærmere analyse af 13 forsøg fra 1999-2001 med ærtesyge har klarlagt en signifikant sammenhæng mellem angreb af ærtesyge på udsæden og udbytteniveauet. For hver procent frø, der blev udsået med ærtesyge, var der et udbyttetab på 0,059 hkg/ha. Ved udsåning af ærter med eksempelvis 20 procent frø med ærtesyge, kan der således forventes et udbyttetab på 1,18 hkg/ha (20 gange 0,059).

The data requirements and the administrative procedure needed for the registration of biological plant protection products and their active ingredients (micro-organisms including viruses, plant extracts, and semiochemicals) are described for the European Union, the USA, Canada und Australia and compared between these systems. Experiences from registration procedures are compared. While data requirements and formalities are rather similar in all systems considered, the time span needed for evaluation and the possibility to predict this time span are quite different. Alternative regulatory measures existing in different regulatory systems are described and initiatives for the facilitation are presented.

Autores: Atanassova, D.; Popova, T.; Todorova, R.
Our study presents a part of the long-term program for resistance breeding to smuts in barley in Bulgaria. 56 dihaploid lines were derived from F1-hybrids of two barley crosses between resistant and susceptible Bulgarian and foreign cultivars bearing the resistant genes Run12 and Run13. The DH progenies were tested in 3 generations for loose smut resistance on the field and in the lab with the embryotest.  10 resistant DH-progenies with gene Run12 and 16 resistant DH-progenies with Run13 were selected and agronomically characterised for new cultivar development.

Strategien zur Reduzierung der Kupferaufwandmengen im ökologischen Kartoffelanbau – Projekt “ÖKO-SIMPHYT“
Provedor de dados: 21
Autores: Benker, M.; Zellner, M.; Bangemann, L.-W.; Kleinhenz, B.; Bartels, G.
Potato late blight (Phytophthora infestans) is still an unsolved problem in organic farming. Up to now the disease can only be controlled by copper fungicides. Our project is aiming to reduce the application of copper-containing fungicides by introduc-tion of the new blight forecasting system “ÖKO-SIMPHYT” based on meteorological parameters. Primary stem infections should be reduced by seed treatment with copper fungicides thus to postpone the beginning of the blight epidemic as well as the start of spraying. To control secondary infections on the foliage, fungicide strategies should be elaborated to achieve best efficacy with reduced amounts of copper. Therefore copper amounts and spraying intervals should be adjusted to the infection pressure. Based on...

Modeling the effect of management strategies on the seed bank dynamics of volunteer oilseed rape
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Holst, Niels; Madsen, Kathrine Hauge.
Seeds of genetically modified (GM) crops remaining in the field after harvest may later emerge as volunteers. These can affect the purity of subsequently harvested crops and cause an uncontrolled flow of GM pollen into the agro-ecosystem. Management strategies that reduce these long-term effects of GM crops include (1) minimizing the input of GM seeds into the soil, (2) preventing proliferation by volunteers and (3) fast depletion of the soil GM seed bank. Formulation of such strategies requires knowledge of the biology of the GM plant (seed loss at or before harvest, seed survival, germination and emergence rates, reproduction, etc.) and of the effect of management practices on the different life stages.    Of the GM crops considered for cultivation in...

Biological activity of Citrus spp. metabolites on Ceratitis capitata (Wiedemann).
Provedor de dados: 21
Autores: Faraone, Nicoletta; Caleca, Virgilio; Bruno, Maurizio; Vitagliano, Silvia; De Cristofaro, Antonio.
The Mediterranean fruit fly (medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is one of the most injurious pest at global level. During the last years, several electrophysiological and behavioural studies have been carried out in order to investigate plant volatile compound-insect interactions with the aim to use this knowledge in sustainable control techniques.  It has been observed that lemons are not attacked by medfly, probably because of the peel oil, that is toxic to other fruit flies. In the present paper electrophysiological recordings were conducted to evaluate the insect sensitivity to peel extract and peel oil of two Sicilian cultivars (Interdonato and Lunario) of Citrus x limon (L.) Burm.f. on C. capitata females. Behavioural...

Comparing two models of the diurnal temperature cycle for simulations of crop and pest phenology under climate change
Provedor de dados: 21
Autores: Felber, Raphael; Fuhrer, Jürg; Stöckli, Sibylle; Calanca, Pierluigi.
Air temperature is the most important determinant of crop and pest phenology. Developmental rates of organisms are thus usually modelled as a function of growing degree-days. These can be evaluated based on either daily or hourly temperatures. However, as climate model do not provide reliable information at high temporal resolution, statistical or empirical models are needed to generate hourly temperature data for assessing crop and pest phenology under climate change.  We present the comparison of two approaches for generating hourly temperatures from daily values of the minimum (Tmin) and maximum (Tmax) temperature. The statistical downscaling approach proposed by Hirschi et al. (2012) uses a nearest neighbour re-sampling procedure to prescribe realistic...

Die positive Korrelation zwischen einem hohen Kalziumgehalt in den Früchten und guter Qualität wird von der Literatur zusammengefasst. Die traditionellen Kalziumspritzungen sind nicht ideal (Synthetische Ursprung, Schalenberostung, Sonnebrand). Wir forschen nach Möglichkeiten für Obstbauern weniger abhängig zu sein von Kalziumchlorid und doch qualitatives Obst zu bekommen.  Bei unserer Beurteilung der Kulturmaßnahmen in Bio Obstbau ist der Kalziumgehalt der Früchte eines der Kriterien. Positiv in diesem Rahmen haben sich gezeigt: ein lebendiger Boden, Begrünung, besonders Klee, Begrenzung des Wuchsniveaus, gute Qualität Rosettenblätter, Früchte an der Basis des Triebes und Früchte mit viele Samen.

Evolutionary plant breeding for low input systems
Provedor de dados: 21
Autores: Phillips, Scott; Wolfe, Martin.
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases.  An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural  election for mass sorting of the progeny in successive natural cropping environments. Composite cross...

Bremia lactucae an Salat - Erarbeitung einer Entscheidungshilfe zur Sortenwahl
Provedor de dados: 21
Autores: Gärber, Ute; Idczak, Elke; Behrendt, Ulrike.
Erreger des Falschen Mehltaus an Salat ist der Pilz Bremia lactucae. Der Pilz besitzt eine hohe Variabilität und hat durch die Entwicklung neuer Rassen mehrfach die durch Züchtung erzielte Resistenz durchbrochen. Die Befallsgefahr hat insbesondere im ökologischen Anbau zugenommen, da direkte Regulierungsmaßnahmen fehlen. Die Entwicklung ständig neuer Erregerformen sowie das lokale Vorkommen einer Vielzahl an Erregerformen, erschweren dem Anbauer, die "richtige", resistente Sorte auszuwählen. Daher soll eine Methode erprobt werden, die es dem Anbauer ermöglicht, entsprechend der regionalen Anbausituation die Sorten auszuwählen, für die im Feld eine nur geringe Anfälligkeit zu erwarten ist.

Abstract: Effects of compost applications on foot diseases and biomass yield of winter peas. A field experiment was conducted to assess the effects of compost applications on the growth and health of winter peas from September 2009 to May 2010. A total of 5 t DM ha-1 of a 12 month old yard waste compost were applied in plots that were either uninoculated or inoculated with Phoma medicaginis grown on infested oat kernels. The control treatment received no compost and was left uninocu-lated. Main plots received all four treatments and were replicated four times. Compost slightly reduced the incidence of Mycosphaerella pinodes and Phoma medicaginis in March and the foot disease severity in May. Overall fresh matter production was significantly reduced by...

Backweizen ist eines der wichtigsten Produkte des ökologischen Landbaus, dessen Erzeugung in Hinblick auf die erforderliche Qualität leider großen Schwankungen und Risiken unterworfen ist. Zur Synthese von Eiweiß, im Falle der Backqualität von Korneiweiß, ist eine genügende N-Nachlieferung aus dem Boden in späten Wachstumsstadien nach der Blüte notwendig. Hier besteht im ökologischen Landbau in der Regel ein deutlicher Mangel.

Shifts in the composition of plant parasitic nematodes under different tillage sytems, living mulch, and compost application
Provedor de dados: 21
Autores: Schmidt, Jan Henrik; Šišić, Adnan; Bacanovic, Jelena; Hallmann, Johannes; Finckh, Maria R.
Plant parasitic nematodes may cause massive yield reductions in organic farming. Long rotations, often high amounts of weeds and a high frequency of legumes favour parasitic nematodes with a broad host range such as Meloidogyne spp. und Pratylenchus spp. The EU- Projekt OSCAR (Optimizing Subsidiary Crop Applications in Rotations) aims at improving soil conservation through minimum tillage combined with living mulches, cover crops and the use of suppressive composts. An experiment was set up with a rotation of 2-year grass-clover mix followed by wheat and then potatoes. Experimental factors were tillage, cover crops, and compost application. Until now Nematodes were sampled before and after wheat and before potatoes. Population dynamics over time were more...

The need to breed crop varieties suitable for organic farming, using wheat, tomato and broccoli as examples: A review
Provedor de dados: 21
Autores: Lammerts van Bueren, E. T.; Jones, S.S.; Tamm, L.; Murphy, K.M.; Myers, J. R; Leifert, C.; Messmer, M.
It is estimated that more than 95% of organic production is based on crop varieties that were bred for the conventional high-input sector. Recent studies have shown that such varieties lack important traits required under organic and low-input production conditions. This is primarily due to selection in conventional breeding programmes being carried out in the background of high inorganic fertilizer and crop protection inputs. Also, some of the traits (e.g., semi-dwarf genes) that were introduced to address problems like lodging in cereals in high-input systems were shown to have negative side-effects (reduced resistance to diseases such as Septoria, lower protein content and poorer nutrient-use efficiency) on the performance of varieties under organic and...

Det var generelt et høgere innhold av de enkelte mikromineralene i andre slått enn i første slått. Flere av planteprøvene viste så lavt innhold av sink at det kan redusere avlingsnivået. Mikromineralinnholdet i kløver var høyere enn i den samlede fraksjonen av gras, kløver og urter, slik at økt kløverinnhold i enga er viktig for å øke innholdet av mikromineraler i fôret Ut fra mineralbehovet hos sau- og storfe viste plante- og blodprøver at flere av besetningene hadde for liten tilførsel av selen og E-vitamin, mens tilførselen av kobolt og kopper stort sett var tilfredsstillende.

Biological control of the cherry fruit fly, Rhagoletis cerasi L. (Diptera, Tephritidae)  by use of entomopathogenic nematodes: first experiences towards practical  implementation.
Provedor de dados: 21
Autores: Herz, Annette; Köppler, Kirsten; Vogt, Heidrun; Elias, Ellen; Peters, Arne; Katz, Peter.
The use of entomopathogenic nematodes (EPN) is a promising approach to control the cherry fruit  fly, Rhagoletis cerasi L.. We already demonstrated the high potential of EPN to infect larvae after  leaving the cherry for pupation in the soil in laboratory and field experiments. For practice, an application  technique is needed, that is both, grower- and EPN friendly. We tested a tractor mounted  spray boom for treatment under the canopy area. The achieved rate of EPN in the soil met the expectations.  The activity of EPN in soil samples was high after application, but dropped to 60% of the  initial activity within one week. Exact forecasting of larval drop from cherries is another major challenge.  To obtain basic data, we recorded the phenology of...

Survey on natural occurrence of Cydia Pomonella granulovirus in apple orchards of Iran
Provedor de dados: 21
Autores: Rezapanah, M.; Kharrazi-Pakdel, A.; Kamali, K.; Huber, J.
The Cydia pomonella granulovirlls (CpGV) is a very effective biological control agent against codling moth, Cydia pomonella L. (Lep.: Tortricidae). Its isolation from natural populations of codling moth is difficult and only a few isolates have been described in the world, because diseased larvae usually rupture and disintegrate and can not be found on the trees. So, in this survey, lots of corrugated cardboard trap bands were placed around the trunks of apple trees in different regions of Iran and they were surveyed for codling moth larvae infected by CpGV. At least, 11 natural isolates from Northwest and Northeast of Iran were collected and surveyed. Viruses from single or pooled infected larvae were isolated and propagated in the fourth in star larvae...

Appropriate disease assessment methods and parameters reflecting whole-season disease severity levels in field plots remain important issues in studies related to plant disease epidemiology, disease resistance of crop cultivars, and disease-induced yield losses. Such methods and parameters should be yield-related to ensure relevance. Net blotch severity was determined over time in inoculated and non-inoculated field plots of three spring barley varieties by whole plot assessments and by assessments of individual leaves of single main tillers. Disease severity measures such as the area-under-disease-progress-curve, mean and maximum severity as well as severity levels at specific growth stages (GS) were derived from the data. Their relation to thousand grain...

Provedor de dados: 21
Autores: Muljar, Riin; Karise, Reet; Mänd, Marika.
Hahkhallitus on aedmaasikal suuri saagikadusid põhjustav seenhaigus (Døving ja Mage, 2001; Williamson jt., 2007), mille tõrjumine keemiliste taimekaitsevahenditega on mahetootjale keelatud. Seetõttu on tekkinud vajadus alternatiivsete taimekaitsemeetodite järele, mis oleks loodust säästvamad ning sobiks ka kasutamiseks mahepõllumajanduses. Üheks selliseks alternatiiviks on entomovektortehnoloogia – biotõrje meetod, kus pulbrilisi biopreparaate viivad taimeõitele mesilaselaadsed putukad.

Livet i jorden
Provedor de dados: 21
Autores: Elmholt, S.; Holmstrup, M.
Når jordbundens mikroorganismer og smådyr har det godt, er jorden som regel også god at dyrke planter i. Og jordbundens levende organismer trives, hvis de får rigeligt med næring og fred og ro. Det første kan økologiske jorde levere, men på grund af mekanisk ukrudtsbehandling ofte ikke det sidste. En mindre del af de konventionelt dyrkede marker giver jordbundsorganismer lige så gode betingelser, så økologisk dyrkning er ikke en absolut betingelse for et godt jordliv.

Resistance Breeding in Apple at Dresden-Pillnitz
Provedor de dados: 21
Autores: Peil, A.; Dunemann, F.; Richter, K.; Hoefer, M.; Király, I.; Flachowsky, H.; Hanke, M.-V.
Resistance breeding in apple has a long tradition at the Institute of Fruit Breeding now Julius Kuehn-institute in Dresden-Pillnitz. The breeding was aimed at the production of multiple resistance cultivars to allow a more sustainable and environmentally friendly production of apple. In the last decades a series of resistant cultivars (Re®-cultivars) bred in Dresden-Pillnitz has been released, ‘Recolor’ and ‘Rekarda’ in 2006. The main topic in the resistance breeding programme was scab resistance and the donor of scab resistance in most cultivars was Malus x floribunda 821. Due to the development of strains that are able to overcome resistance genes inherited by M. x floribunda 821 and due to the fact that single resistance genes can be broken easily,...

Alleyway groundcover management and scab resistant apple varieties
Provedor de dados: 21
Autores: Pedersen  , Hanne Lindhard; Bertelsen, Marianne.
The use of scab resistant apple varieties is the best way to prevent inflections of apple scab (Venturia inaequalis). In 1995 the then 10 most promising resistant apple varieties for Denmark where planted at Research Centre Àrslev, Denmark in an organic production system. Three different cover crops where established in the alleyways. Weed cleaning in the tree row was done mechanically and the trees were kept unfertilised.  The annual shoot growth, nutrients in leaf sample, mineralised nitrogen in soil, content of water in the upper 50 cm soil, Fruit yield and Fruit quality were assessed.  The annual cover crop caused the longest shoot growth, the highest content of nitrogen in leaves and soil, the smallest competition with the trees concerning soil water...

Qualität und Ertrag von Öko-Zwiebeln: Vergleich von Pflanzung und Direktsaat
Provedor de dados: 21
Autores: Bufler, Gebhard; Hübner, Oliver; Funk, Rainer.
Yield and quality (bulb size, sugar content and composition, pungency, initial sprout growth) of early and late transplanted and directly sown onions (cv. Sturon) were compared in field experiments (2009-2011) at different intensities of weeding (weed-free or mechanical weed control only). Early transplanting (weed-free) resulted in the highest yield and best quality performance, whereas late transplanting combined with mechanical weed control  only (including harrowing weeds before transplanting onions) resulted in medium yield and quality, however, at a relatively low work-input. It is suggested that infection by powdery mildew was the key limiting factor in the development of yield and quality in late-transplanted and directly-sown onions.

IL RUOLO DEL GENERE TRICHOGRAMMA NEL CONTENIMENTO DELLE INFESTAZIONI DI MAMESTRA BRASSICAE (L.) SU COLTIVAZIONI BIOLOGICHE DI CAVOLO IN PROVINCIA DI TORINO
Provedor de dados: 21
Autores: PINNA, MASSIMO; SPAGNOLO, SANDRA; GAMBA, URSULA.
Il lepidottero nottuide Mamestra brassicae L. rappresenta un grave problema per le  coltivazioni di cavolo verza presenti in provincia di Torino; le uova, deposte sulla  pagina inferiore delle foglie, sono spesso difficili da individuare e le larve, che si generano da esse, vengono individuate dagli agricoltori quando hanno ormai raggiunto  dimensioni notevoli, tali da renderle meno sensibili agli insetticidi.  Gli Imenotteri Tricogrammatidi possono rappresentare un efficace fattore naturale di  contenimento di questi insetti, ma la loro attività è spesso ostacolata dai prodotti di  sintesi impiegati per la difesa della coltura. Anche i principi attivi naturali come piretro e zolfo bagnabile possono influenzare la loro presenza; alcune osservazioni...

Effect of sowing date and straw mulch on virus incidence and aphid infestation in organic faba-beans (Vicia faba L.)
Provedor de dados: 21
Autores: Saucke, H.; Juergens, M.; Döring, Th. F.; Lesemann, D.E.; Fittje, S.; Vetten, H.-J.
The effect of sowing date on aphid infestation and the incidence of aphid-transmitted viruses were investigated in organically managed, small-scale field experiments with two faba bean cultivars over 3 years (2002–04). As an additional factor, strawmulchwas applied in 2 of the 3 years shortly before the start of vector activity in May. Virus incidence was determined using enzyme-linked immunosorbent assay and immunoelectron microscopy. Aphid flight activity was monitored using standard yellow water traps. Bean colonising aphids were assessed throughout the vegetation period by counting the number of plants infested with Acyrthosiphon pisum, Megoura viciae and Aphis fabae. Pea enation mosaic virus and bean yellow mosaic virus were the most abundant...

Detecting key parasitoids of lepidopteran pests by multiplex PCR
Provedor de dados: 21
Autores: Traugott, Michael; Zangerl, Petra; Juen, Anita; Schallhart, Nikolaus; Pfiffner, Lukas.
The use of diagnostic polymerase chain reaction (PCR) is a valuable approach to study host–parasitoid interactions. It circumvents problems inherent to rearing parasitoids from Weld-collected hosts or host dissection. Here, we present a PCR-based detection method for Diadegma semiclausum, Cotesia glomerata, and Cotesia rubecula, which are key parasitoids of the three lepidopteran cabbage pests Plutella xylostella, Pieris brassicae, and Pieris rapae, respectively. Primer pairs for the three parasitoid species and Pl. xylostella were developed: they were used either separately in singleplex PCR or combined in multiplex PCR to (1) screen simultaneously for the two Cotesia species or to (2) detect the parasitoid D. semiclausum and identify its host Pl....

Ertragseinbusse beim Anbau von Erbsen und anderen Leguminosen?
Provedor de dados: 21
Autores: Hohmann, Pierre.
Leguminosen wie die Erbse verbessern die Bodenfruchtbarkeit. Sie sind daher eine wichtige Komponente im biologischen Anbau. Fehlende Resistenzen gegen bodenbürtige Erreger in modernen Sorten führen jedoch vermehrt zu Ertragseinbussen. Die Erreger überleben lange im Boden und können sich mit der Zeit anreichern. In Deutschland werden mittlerweile bei Erbsen Anbaupausen von bis zu 10 Jahren empfohlen. Damit es in der Schweiz erst gar nicht so weit kommt, beschäftigt sich das FiBL intensiv mit der «Leguminosenmüdigkeit ». Bereits liegen vielversprechende Forschungsergebnisse zu Resistenzen, Mischkulturen oder Kompost vor.

The field experiment was conducted at Tushikamane Centre  Kilakala, Morogoro Tanzania to investigate the effect of EM technology on maize (Zea mays L.) growth, development and yield. Maize is a major cereal consumed; over 80% of population depends on maize for food in Tanzania. Low soil fertility, insect pests and diseases are among the primary constraints in maize production. This is due to continuous cultivation without fertilizing the soil, poor and lack of proper measures to control pest and diseases. Most farmers in both rural and urban areas of Tanzania are not aware with the use of organic fertilizers especially the EM (Effective Microorganism) technology in agriculture to increase crop yield without the use of agricultural chemicals or artificial...

Einfluss von reduzierter Bodenbearbeitung, Zwischenfrüchten und Kompostdüngung auf pflanzenparasitäre Nematoden im Ökolandbau
Provedor de dados: 21
Autores: Schmidt, Jan Henrik; Bleher, K.; Hallmann, Johannes; Finckh, Maria R.
Pflanzenparasitäre Nematoden (PPN) können im ökologischen Landbau zu erheblichen Ertragseinbußen führen. Die langen Fruchtfolgen und zumeist stärkere Unkrautvorkommen führen im Allgemeinen zu einem häufigeren Auftreten von PPN mit einem breiten Wirtsspektrum. Meloidogyne spp. und Pratylenchus spp. zählen zu den wirtschaftlich bedeutendsten Gattungen. Ihr endoparasitisches Verhalten bewirkt, dass bereits eine geringe Anzahl dieser PPN zu Schäden an Kulturpflanzen führen kann.

BACKGROUNd  There is growing demand to replace chemical pesticides with alternatives owing to concerns related to impacts on human health and the environment. Plant-derived plant protection products could provide sustainable and environmentally friendly alternatives to chemical products. The aim of this study was to identify plant and fungal extracts with so far unknown activity against important plant pathogens by in vitro screening of a library of more than 3000 extracts.  RESULTS  Several plant extracts with promising in vitro fungicidal activity (MIC100 ≤ 50 µg mL−1) towards one or several of the investigated pathogens (Venturia ineaqualis, Phytophthora infestans, Plasmopara viticola) were identified by the screening. One of the hits, an ethyl acetate...

Interactions of summer pruning techniques and vine performance in the white cultivar Ortrugo (Vitis vinifera L.)
Provedor de dados: 21
Autores: Gatti, Matteo; Garavani , A; Cantatore, A; Poni, Stefano.
Background and Aims: The increasing interest by the wine market in sparkling white wines challenges how the  desired grape composition can be achieved under the pressure of global warming. The aim of the present study was  to assess the viability of summer pruning as a tool to pilot ripening towards desired compositional patterns.  Methods and Results: Ortrugo was subjected to basal leaf removal applied either at pre-flowering (ELR) or in  lag-phase (LLR) and to bunch thinning (BT; removal of 50% of crop at lag-phase) in comparison with untreated  control (C). Treatments induced large variation in bunch mass (30% less in ELR vs BT), yield per vine (37 and 21%  less in BT and ELR vs C) and total soluble solids at harvest (BT scored 2.9°Brix higher than that...

Die Kirschessigfliege – ein neuer Schädling im Weichobstanbau
Provedor de dados: 21
Autores: Daniel, Claudia; Baroffio, Catherine.
Die Kirschessigfliege Drosophila suzukii wurde 2008 nach Europa eingeschleppt und hat im Mittelmeerraum bereits für starke Schäden gesorgt. Im letzten Sommer wurde der neue Schädling erstmals auch in der Schweiz nachgewiesen. Die Fliegen befallen alles Weichobst (Beeren, Kirschen, Trauben) sowie viele Wildfrüchte. In diesem Jahr sollten alle sensiblen Kulturen mit Apfelessig-Fallen überwacht werden. Zur Befallsvorbeugung werden der Einsatz von engmaschigen Netzen, Massenfang mit Fallen sowie das Vernichten befallener Früchte empfohlen. Das BLW hat den Einsatz von Spinosad und Pyrethrum unter Auflagen bewilligt.

Biological activity of glucosinolate derived compounds isolated from seed meal of Brassica crops and evaluated as plant and food protection agents
Provedor de dados: 21
Autores: Bellostas, N.; Casanova, E.; Garcia-Mina, J.M.; Hansen, L.M.; Jørgensen, L.N.; Kudsk, P.; Madsen, P.H.; Sørensen, J.C.; Sørensen, H.
Glucosinolates are amino acid derived allelochemicals characteristic of plants of the order Capparales. These compounds are present in seeds of agriculturally common Brassica crops in varying quantities depending on the species (ref). The use of the remaining seed cake after oil extraction has traditionally been limited by the concentration of these compounds. However, the extraction of glucosinolates from seed meal is nowadays possible and it further contributes to an increased quality of the seed meal for feed (Sørensen et al., this conference). Glucosinolates are hydrolysed by endogenous enzymes (myrosinases; EC 3.2.1.147) and a number of compounds are produced depending on the parent glucosinolate and the environmental conditions.1 Among these...

Autores: Schulte Geldermann, Elmar; Dlugowski, Susanne; Finckh, Maria R.; Bruns, Christian.
Three potato varieties – Nicola, Rosella, and Simone, differing in the time of initiation of tuber formation (early, middle, late, respectively) – were grown in a 3-factorial field trial for two years in 2 rotational positions i. e. after grass clover and winter wheat in order to induce a different fertility status. A copper control was included. Nitrogen supply after grass clover was between 26 to 32 kg higher than after winter wheat. Late blight severity was high in 2002 but almost nil in 2003 (Area under the curve 1100 versus 75, respectively). In both years, it was consistently but not significantly higher after grass clover. N-mineralisation rates in 2002 were below average due to unfavourable weather conditions in May and June. Thus, only in 2003 the...

Schurft optimaal bestrijden met een minimale hoeveelheid koper
Provedor de dados: 21
Autores: Hemelrijck, Wendy.
Door de mogelijke schadelijke effecten, bv. door een te hoge hoeveelheid aan koper in de bodem, staat het gebruik van koper in de land- en tuinbouw ter discussie, ook in de biologische teelt van pitfruit. Desondanks de vele studies zijn er tot op heden nog geen andere middelen ter beschikking om koper te vervangen. Tot op heden is het weglaten van preventieve koperbehandelingen uit de managementstrategie naar schurft in de biologische teelt dus ondenkbaar.    Toch worden vanuit de Biovakgroep pitfruit inspanningen gedaan om het gebruik van koper te doen dalen indien mogelijk.     Daarom werd, in samenwerking met de Biovakgroep pitfruit, een project uitgevoerd waarin werd nagegaan of er voor de beheersing van schurft bij Conference kan gebruik gemaakt...

Weed control in organic farming
Provedor de dados: 21
Autores: Dryjańska, Elżbieta.
This website article explains direct and indirect measures for weed management in organic farming, focusing on the importance of crop rotation.  It recommends for example cultivating broad-leaved, fast growing and soil-improving plants, such as buckwheat, pea, vetches, white mustard, legumes and lucerne. An important element is fodder crops, which weaken annual and perennial weeds through multiannual cutting regimes and cutting of the shoots. The article mentions the major role root crops and intercropping play in suppressing weeds. Insufficiently processed compost and decomposed manure can be a source of weeds as well as unclean seeds and machinery.  Apart from preventive measures, the article lists agrotechnical methods, like stubble cultivation,...

Pathogenicity in Verticillium on strawberry plants
Provedor de dados: 21
Autores: Schubert, P.; Golldack, J.; Schwärzel, H.; Lentzsch, P.
In the most common strawberry cv. ’Elsanta’, Verticillium infection can lead to rapid wilt  and even death of plants. It is known, that a dead plant can be located directly beside vital  ones. In a survey of 8 fields in Brandenburg, Mecklenburg- Vorpommern, Sachsen-Anhalt  and Sachsen, 432 genotypes of Verticillium dahliae Kleb. were isolated from wilted and  even vital plants from 8 fields and classified by PCR-fingerprints. For strawberries, the  genotypes can be classified as apathogenic, weakly and highly pathogenic according to  the results of climate chamber experiments on strawberry transplants.  At landscape scale, similarity analysis of the PCR fingerprints of 432 genotypes resulted in  13 genetic subtypes. Several of these subtypes occurred at...

Autores: Luka, Henryk; Barloggio, Guendalina; Pfiffner, Lukas.
Die Regulation von Schädlingen kann im Bio-Gemüsebau mit Hilfe von Biodiversitätsflächen verbessert werden. Dies zeigen mehrjährige Untersuchungen am Modellsystem Kohl, am Schädling Kohleule und an dessen Ei- und Larvenparasitoiden (Nützlinge).  Gefördert wurden die Nützlinge durch Blühstreifen am Feldrand und Beipflanzen innerhalb des Feldes. Geeignete Pflanzen für die Blühstreifen wurden aufgrund der Fachliteratur und eigener Laborexperimente ausgewählt und in Feldversuchen überprüft. In Laborversuchen verlängerte das Angebot von Buchweizen, Kornblumen oder Futterwicken die Lebensdauer der Kohleulen-Parasitoide um 43 bis 85%. Die Parasitierung der Kohleule-Larven erhöhte sich im Vergleich zur Kontrolle um das Drei- bis Sechsfache. In den Feldversuchen...

Cross vane funnel bucket traps with water and detergent captured significantly more A. rubi than sticky traps. L. rugulipennis catches were higher in the cross vane traps, but catches were impeded by the bee excluder grid. There were fewer of the target pest species captured on sticky traps and these devices tended to capture significantly more by-catch (e.g. Diptera) including beneficial insects, e.g. spiders and Carabidae. In the second experiment, the height of the green cross vane had no effect on the numbers of male L. rugulipennis trapped in the funnel traps. However, the higher cross vanes captured more coccinelids and opiliones. In the A. rubi trials there were significantly more individuals in the full height cross vane compared to the half-height...

Regulierung des Kleinen Fruchtwicklers im ökologischen Obstbau
Provedor de dados: 21
Der Kleine Fruchtwickler Grapholita lobarzweskii, der bis dato im süddeutschen Raum eher als Nebenschädling betrachtet wurde, entwickelt sich vor allem im Bodenseegebiet zunehmend zum Problemschädling (Befall bei der Ernte im Jahr 2002 bis zu 30%). In Deutschland steht zur Zeit kein für den ökologischen Obstbau zulässiges Bekämpfungsverfahren zur Verfügung. Ziel des Projektes ist es daher, die Regulierung des Kleinen Fruchtwicklers zu optimieren. Hierbei sollen folgende für den ökologischen Obstbau zugelassene Pflanzenschutzmittel und deren Kombinationen getestet werden: XenTari, NeemAzal-T/S, Quassia. Ausserdem soll die Wirkung der Verwirrungsmethode in starken Befallslagen überprüft werden. Weiterhin soll untersucht werden, inwiefern Parasitoide als...

Einsatz moderner Züchtungsstrategien zur Verbesserung der Eigenschaften von Sommerbraugerste für den ökologischen Landbau
Provedor de dados: 21
Autores: Herz, Markus; Aschenbach, Birte; Müller, Karl-Josef.
Sommergerste ist im ökologischen Landbau nach Weizen, Hafer und Dinkel die Getreideart mit der höchsten Bedeutung für die verarbeitende Industrie. Der Markt für Öko-Braugerste ist in den letzten Jahren rasch gewachsen. Der gestiegenen Nachfrage steht ein knappes Angebot aus deutscher Erzeugung gegenüber, so dass viele Mälzereien zu Importen gezwungen sind. Voraussetzung für eine stärkere Verbreitung des Sommergerstenanbaus im ökologischen Landbau ist die Bereitstellung geeigneter Sorten. Für die Sommergerste sehen Vertreter der Ökolandbau-Beratung einen hohen Bedarf an Züchtung und Züchtungsforschung. Resistente Sorten haben im Ökolandbau besonders große Bedeutung.  Im Rahmen des Projektes konnten unter konsequenter Anwendung von Strategien der...

Vorratsschädlinge im ökologischen Landbau
Provedor de dados: 21
Autores: Schleuß, Uwe.
Der Artikel bezieht sich auf die Ergebnisse des im Juni 2002 veranstalteten 8. Fachgespräches "Pflanzenschutz im ökologischen Landbau". Die Thematik der Veranstaltung bezog sich auf Fragen des Vorratsschutzes unter den Produktionsbedingungen des ökologischen Landbaus.  Zusammenfassend lässt sich aus den Ergebnissen schließen, dass dem Vorratsschutz in den vergangenen  Jahren zu wenig Aufmerksamkeit gewidmet wurde. Ein Indiz dafür ist die geringe Forschungskapazität, die für dieses Fachgebiet in Deutschland zur Verfügung steht. Das Hauptaugenmerk im Vorratsschutz ist auf die Schädlingsvermeidung durch geeignete Lagerungstechnik und gezielte Hygiene zu fokussieren. Unter kühlen, trockenen und sauberen Lagerungsbedingungen ist bei laufender Überwachung des...

An assessment of nitrogen fixation in 'organically managed' spring-sown lupins and leaching under a following winter cereal
Provedor de dados: 21
Autores: Joynes, A; Hatch, D; Stone, A.
Three spring-sown species of lupins (Bora, Prima and Wodjil) and peas were compared in terms of N fixation and subsequent leaching under a following winter cereal crop. Although peas out-yielded lupins (5.4 t compared with ca 3.5 t grain, respectively), the yellow lupin (Wodjil) fixed more N than peas (180 compared with 120 kg N ha-1) and all three lupins contained more protein (&gt; 30%) than the peas (22%). Wodjil was the most effective at suppressing weeds, carrying only 12% of the weed burden found in fallow plots, followed by peas (19%). Winter leaching amounted to &gt; 50 kg nitrate-N ha-1 from under the winter cereal, regardless of whether the previous treatment was a legume crop or was left fallow. There were no significant differences in leaching...

Autores: Lambion, Jérôme; Bellec, Anne-Gaelle.
Le mildiou des cucurbitacées (Pseudoperonospora cubensis) est la maladie aérienne la plus grave sur concombre en Agriculture Biologique. L’attaque est souvent foudroyante : concombre et mildiou appréciant tous deux des atmosphères chaudes et humides, il est difficile de jouer sur l’aération des tunnels pour limiter le développement de la maladie. De plus, les moyens de lutte disponibles en AB sont très limités (pas de variétés résistantes, produits fongicides encore peu efficaces et pas encore d'homologation contre le mildiou).

Entwicklung und Darstellung von Strategieoptionen zur Behandlung von Saatgut im ökologischen Landbau
Provedor de dados: 21
Die Verwendung gesunden Saatguts spielt eine große Rolle im ökologischen Landbau. Zum einen, da schlechte Saatgutqualität einen lückigen Aufgang des Saatguts und somit Ertrags- und Qualitätseinbußen bedeutet und zum anderen, weil in den nächsten Jahren ein möglichst vollständiges Zurückgreifen auf Öko-Saatgut angestrebt wird. Trotzdem liegt bislang für Landwirte keine praxisorientierte Übersicht für jeweils geeignete Saatgutbehandlungsverfahren vor. Ziel des Vorhabens ist daher, bisher vorliegende Angaben zu Verfahren und Präparaten zur Saatgutgesunderhaltung zusammenzutragen, sie auf ihre Tauglichkeit zu prüfen und - wenn möglich und notwendig - für die Praxisanwendung weiter zu entwickeln. Darauf aufbauend sollen Leitfäden zur Saatgutgesundheit im...

Rhizospheric changes of fungal and bacterial communities in relation to soil health of multi-generation apple orchards
Provedor de dados: 21
Autores: Caputo, F.; Nicoletti , F.; De Luca Picione , F.; Manici, L.
The study focused on changes of rhizosphere microbial communities in apple trees in long-term replanted orchards of Central Europe, aiming at developing cropping practices to mitigate replant problems. It started from the evidence of a previous study which showed that a slight modification  of root-colonizing fungal communities was responsible for a great increase of plant growth in soil samples which had previously been subjected to a gamma-irradiation cycle (25 kGy for 8 h), as compared to that observed in the corresponding untreated native soils.  The study was performed on rhizospheric soil from nine multi-generation apple orchards after a plant growth assay with M9 rootstock plantlets. PCR-DGGE analysis of soil DNA was performed to evaluate fungal and...

Entwicklung und Praxiserprobung eines neuen Züchtungskonzeptes für einen stabilen ökologischen Salatanbau
Provedor de dados: 21
Trotz steigender Nachfrage nach Salaten aus dem „Bio-Sektor“ stagniert der heimische Anbau. Grund ist die fehlende Anbausicherheit. Krankheiten wie der Falsche Mehltau und abiotische Schadfaktoren führen häufig zu starken Ertragsverlusten. Auf dem Markt fehlen Sorten, die eine große Anbausicherheit im ökologischen Anbau mit einer guten Produktqualität vereinen. In den BÖLN-Projekten 2810OE064/069 wurden erstmals neue Züchtungsmethoden erprobt. Dabei zeigte sich, dass die Arbeit mit Kreuzungspopulationen und der Anbau von Liniengemischen geeignete Lösungswege sind, um Ertragsstabilität zu erreichen. Möglich wird dies durch eine höhere Variabilität durch die Durchmischung des Bestandes bzw. die Genetik, wodurch eine variablere Reaktion auf Stressoren gegeben...

Nowadays, organically produced products have become more popular than ever and interest in them is still   growing fast. The early blight causal pathogen Alternaria solani has not been considered a great threat to potato in   northern climate conditions in the past and has not been routinely sprayed against. During our study early blight   was evaluated in 2010 and 2011 on the plants of a potato cultivar ‘Reet’ in an organic farming experiment. In our   study, both growing seasons were very favourable for early blight development. Significant differences between   the two cultivation technologies were found (F1,12 = 4.84, p = 0.048). In 2010, the area under disease progress curve   (AUDPC) value was 303 on cover crop (CC) plots and 990 on CC + M (manure)...

Autores: Jermini, Mauro; Gusberti, Michele; Trivellone, Valeria; Wyss, Erich; Linder, Christian.
Flavescence dorée and the mandatory control of its vector Scaphoideus titanus pose  important problems in organic vineyards. The goal of our field studies conducted in the  Ticino was to develop a pest control strategy conform to the guidelines of organic  production. Insecticides containing pyrethrin were the only organic products showing  an efficacy higher than 90% against the immature stages of S. titanus. However, these  products had no effect on adult leafhoppers. Repeated applications of pyrethrin  proved to be toxic against the predatory mite species Amblyseius andersoni. Despite  this toxicity, the only efficient and recommended control strategy in organic vineyards  is their application. Pyrethrin should be applied three times at an interval of...

The overall objective is to determine, if conventional and organic food products show differences in effects on animal physiology, of a type and magnitude, that indicates that such products will affect humans differently. The agricultural treatments used are:   1: An organic cultivation treatment, with low input of nutrients through animal manure and use of catch crops, and no pesticides.  2: A conventional cultivation system, with high input of nutrients through mineral fertiliser and intensive use of pesticides.  3: A combination of 1 and 2, with low input of nutrients, primarily animal manure, and intensive use of pesticides.     The treatments will be established on two sites. Wheat, potatoes and oilseed rape will be produced in Foulum, and carrots,...

Susceptibility of different life stages of Rhagoletis cerasi to entomopathogenic fungi. The effects of six fungus strains (Deuteromycotina: Hyphomycetes) on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), were assessed in a series of laboratory experiments. All fungus strains caused mycoses in larvae and adults of R. cerasi. Virulence however varied considerably between the strains. Effects on L3-larvae were negligible; none of the fungus strains caused mortalities of more than 25% of larvae. Adults by contrast were highly susceptible to fungal infection. Beauveria bassiana and Paecilomyces fumosoroseus caused 90 to 100% mortality and had a strong influence on fecundity. Metarhizium...

Autores: Bomford, Michael K.; Vernon, Robert S.; Päts, Peeter.
Fine nylon mesh fences (135 cm high) with varying lengths of downward-sloping collection overhangs were evaluated for efficacy in excluding the female cabbage flies Delia radicum (L.) from plots of radish, Raphanus sativus (L.). During three trials conducted in 1994 and 1995, fences without overhangs, fences with 12.5-cm overhangs, or fences with 50-cm overhangs were tested against fences with standard 25-cm overhangs and unfenced control plots. In fenced plots with standard 25-cm overhangs, the mean number of D. radicum females caught on yellow sticky traps placed within plots was 85% less than those caught in corresponding control plots.

Varieties of field vegetables and potatoes for organic production and marketing OF0304
Provedor de dados: 21
Autores: Unspecified,.
The objectives of the work were to investigate the suitability of selected varieties of vegetables and potatoes for organic production using organic or untreated seed on certified organic sites.     Organic growing of vegetables and potatoes imposes restrictions on the treatments which growers can apply to crops to maximise yield and maintain quality.  Hence choice of variety is more critical in organic situations than for conventional crops where problems can be solved at a later date by application of pesticides or fertilisers.  Varieties are needed that can respond to the sometimes sub optimum conditions that are imposed by the restrictions of organic systems and identification of these are not always evident from trials under conventional conditions....

DO LIVING MULCH BASED VEGETABLE CROPPING SYSTEMS YIELD SIMILARLY TO THE SOLE ONES?
Provedor de dados: 21
Autores: Canali, S.; Campanelli, G.; Bavec, F.; von Fragstein, P.; Leteo, F.; Jocop, M.; Kristensen, H.L.
Ecological services may be exploited by use of living mulches in intercropping systems for production of vegetable crops. But may high yields be attained in intercropping systems for production of resource demanding crops such as cauliflower? In the frame of the InterVeg (Core Organic II) project, four field experiments were carried out in IT, SLO, DE and DK in order to study the effect of the living mulch introduction in cauliflower based cropping systems on crop yield and yield quality. The preliminary results, obtained after the first year project, showed yield and produces quality equal to those obtained in the sole cropping system if the system is properly managed (i.e. LM is late sown or its growth is controlled by root pruning).

Wie jede andere Leguminose, kann auch die Sojabohne (Glycine max (L.) Merr.) mit Hilfe von Soja-spezifischen Knöllchenbakterien (Bradyrhizobium japonicum) Luft-Stickstoff binden. Da die Bradyrhizobien natürlicherweise nicht in den mitteleuropäischen Böden vorkommen, müssen die Samen der Sojabohne mit kommerziell verfügbaren Bradyrhizobien-Impfpräparaten inokuliert werden. Beim Anbau hat sich in den letzten Jahren jedoch gezeigt, dass die Inokulation vor allem in kühleren Klimaten bei einzelnen Präparaten zu unzuverlässiger Knöllchenbildung und damit ungenügender Stickstoffbindung führen kann. Ziel dieser Arbeit ist es, die Eignung kommerziell verfügbarer Bradyrhizobien-Impfpräparate zur Inokulation der Sojabohne zu prüfen.

De teelt en afzet van biologische aardappelen is de afgelopen jaren onder grote druk komen te staan. Een belangrijke oorzaak hiervan is de aardappelziekte Phytophthora infestans. Als de ziekte in het gewas komt dan moet het gewas doodgebrand worden. In sommige jaren, zoals in 2007, gebeurde dit al vroeg in het seizoen en was én de opbrengst laag en de kwaliteit onvoldoende. Behalve met resistente rassen zijn er maar weinig mogelijkheden om aan deze beruchte ziekte te ontkomen. Gelukkig komen er steeds meer rassen die minder vatbaar zijn, maar op dit moment zijn de vatbare rassen nog het meest gewild bij retailer en consument.

In Finland most of the long-range migrations of pest insects are carried by warm air currents from south and south-east, by winds blowing from the continent. Changes in climate affect not only local populations, but also the source populations in these migrations. The possible  changes predicted by climate change models in the areas of interest in Finland include longer growing seasons, milder winters, and slight increase in precipitation at the higher latitudes, but also increase in droughts in the southerly areas where many of the migrants are supposed to overwinter. The migratory insect pests can take full advantage of the longer growing season, and monitoring of the migration both in the fields and in the air would be important in making the control...

Der er kommet flere aftagere af spelt på markedet, men markedet for spelt er stadig lille. Produktionen kan derfor hurtig blive for stor. Så en kontrakt på afsætning er en god ide, før man giver sig i kast med dyrkning af spelt. Kvaliteten af den høstede spelt er meget vigtig, da spelt som udgangspunkt kun kan afsættes til melproduktion. Det er især vigtigt at fokusere på faldtallet, da vinterspelt er spirevillig ligesom rug og derfor hurtigt kan blive påvirket af dårligt vejr under modningen.

Strawberry is a fruit crop grown worldwide. There are two main strawberry production systems: open fields and protected cultures (greenhouses or high tunnels). Growing strawberries under high tunnels has many advantages such as protection from different weather conditions, but also disadvantages such as lack of pollinators. The aim of this study was to investigate whether additional pollinators (bumble bees) visit strawberry flowers at different rate under high tunnels compared to open fields. Field experiment was performed to collect and analyze bumble bee corbicular pollen from hives located under high tunnels and open fields. We found that bumble bees under high tunnels gathered more pollen from  plant species (strawberry and white clover) present...

Strategies for controlling seed-borne diseases in cereals and possibilities for reducing fungiside seed treatments
Provedor de dados: 21
Autores: Nielsen, Bent; Borgen, Anders; Nielsen, Ghita; Shceel, Christiane.
In the short term there is no useful alternative to chemical seed treatment for controlling the important seed-borne diseases in cereals. The only way to secure high quality seed is by discarding seed lots which have more than a specified level of disease. Without any other effective control measure than seed treatment large quantities of cereal seeds would be expected to be discarded. Another reduction model might be a differentiated use of seed treatments in the different certified seed generations. An important condition for the models is a representative seed test which for the moment only is possible in spring cereals. The threshold levels for the different diseases should under these circumstances be re-evaluated. In the long term other measurements...

Why farmers should manage the arbuscular mycorrhizal symbiosis
Provedor de dados: 21

The Tansley review by Ryan &amp; Graham (2018) provided a welcome critical perspective on the role of arbuscular mycorrhizal (AM) fungi in large‐scale industrial agriculture, with a focus on cereals (wheat, Triticum aestivum). They conclude that there is little evidence that farmers should consider the abundance or diversity of AM fungi when managing crops. We welcome many of the points made in the paper, as they give an opportunity for self‐reflection, considering that the importance of AM fungi in agroecosystems is often taken for granted. However, we suggest that it is too early to draw the overall conclusion that the management of AM fungi by farmers is currently not warranted.    We offer the following points to contribute to the discussion. The first...

Verbesserung der Krankheitstoleranz von Kulturpflanzen mit resistenzinduzierenden Natursubstanzen (PEN)
Provedor de dados: 21
Die Pioniere des biologischen Landbaus berichten schon seit Jahrzehnten von der pflanzenstärkenden und krankheitsvermindernden Wirkung von verschiedenen Kräutertees, Kompostextrakten, Gesteinsmehlen und bio-dynamischen Präparaten. Mittlerweile wurden derartige Phänomene wissenschaftlich untersucht und unter dem Begriff der induzierten Resistenz zusammengefasst. Für die Entwicklung des Biolandbaus ist es entscheidend, dass Pflanzenschutzpräparate wie Kupfer ersetzt und die Ertragssicherheit generell erhöht wird.  Im Jahre 1997 wurde in einer von der Biochemie GmbH (Kundl, Österreich) und der Universität Basel mitbetreuten Diplomarbeit abgeklärt, ob die Widerstandsfähigkeit von Tomaten, Gurken und Reben gegen Krankheiten mit einem Naturextrakt erhöht werden...

Verminderung gefährlicher Alkaloide in der Nahrungskette durch die züchterische Verbesserung der Mutterkorn-Resistenz von Roggen
Provedor de dados: 21
Roggen ist anfällig gegen Befall mit dem Mutterkornpilz (Claviceps purpurea). Die Überdauerungs-organe (Sklerotien) enthalten eine Vielzahl von Alkaloiden, die für Mensch und Tier äußerst schädlich sind. Gerade ökologisch wirtschaftende Betriebe sind auf die züchterische Verringerung der Mutter-kornbelastung des Erntegutes angewiesen (dünnere Bestände, spätere Saatzeit, diverse Feld(rand)- flora). Im Projekt sollen genetische Ressourcen auf zwei CMS-Tester und Roggenlinien auf ein bis zwei Tester ausgekreuzt werden und die entstehenden Testkreuzungen und Linien je zweijährig an zwei Standorten auf Mutterkornresistenz geprüft werden. Nur durch die Verwendung von CMS kann erstmals die physiologische Resistenz von Faktoren, wie Witterung, Blühverhalten,...

This report is the result of a network project which was established to discuss the potential for collaboration on development of systemic approaches to pest management without pesticides between Chinese and Danish researchers. The focus is on systemic approaches rather than input substitution of synthetic chemicals with agents of natural origin, however, the latter is considered as an integrated tool for the development and design of systemic approaches. The discussions were, furthermore, limited to management of invertebrate pests as well as diseases, while other pests such as weeds have not been included in the discussions. The discussions took place at two workshops and were based on presentations of research from the two countries and field visits in...

La drosofila del ciliegio – un nuovo parassita nelle colture di frutta a polpa tenera
Provedor de dados: 21
Autores: Daniel, Claudia; Baroffio, Catherine.
La drosofila del ciliegio Drosophila suzukii è stata importata in Europa nel 2008 ed ha già causato gravi danni nell’area mediterranea. L’estate scorsa il nuovo parassita è stato per la prima volta segnalato anche in Svizzera. I moscerini attaccano tutta la frutta a polpa tenera (bacche, ciliegie, uva) e diversi frutti selvatici. Quest’anno tutte le colture sensibili saranno monitorate con trappole all’aceto di mele. Per prevenire l’infestazione si raccomanda l’impiego di reti a maglie fini, la cattura in massa con trappole e la distruzione dei frutti infestati. L’UFAG ha permesso, a determinate condizioni, l’uso di spinosad e piretro.

Strategien zur Bekämpfung von Brandkrankheiten bei Getreide im Ökologischen Landbau
Provedor de dados: 21
Autores: Spieß, H.; Lorenz, N.; Müller, K.-J.; Koch, E.; Wächter, R.; Jahn, M.; Waldow, F.; Vogt-Kaute, W.; Wilbois, K.-P.
Getreidebrände als saatgutübertragbare Erkrankungen der Ähre haben im Ökologischen Landbau stärkere Bedeutung erlangt, weil eine Beizung mit hochwirksamen Fungiziden unterbleibt. Eine Bekämpfung ist jedoch zwingend notwendig, weil in der Regel Ertragseinbußen eintreten und die Sporen toxikologisch bedenklich sind. Zudem droht der Saatgutvermehrung Schaden, denn bereits mehr als drei bzw. fünf befallene Pflanzen pro 150 m² führen zur Aberkennung des Basis- bzw. Z-Saatgutes. Resistente Sorten stehen kaum zur Verfügung, denn wegen der Saatbeizung bestand für die Züchtung seit Jahrzehnten keine Notwendigkeit, sich einer Resistenzzüchtung zu widmen. Das spiegelt sich auch in den Zulassungskriterien des Bundessortenamtes wider, wo die Anfälligkeit der Sorten auf...

Evaluation of organic pest management strategies to control the cocoa mirid (Monalonion dissimulatum Dist.), Alto Beni, Bolivia
Provedor de dados: 21
Autores: Ferrari, Leone; Florez, Andrez; Velásquez, Fortunato; Schneider, Monika; Andres, Christian; Milz, Joachim; Trujillo, German; Alcon, Freddy; Fromm, Ingrid.
The cocoa mirid (Monalonion dissimulatum) is one of the major pests in cocoa cultivation in Alto Beni, Bolivia, causing up to 50% yield losses. The most common control method is the manual removal of the nymphs sucking at the pods in the morning. This practice is very time-consuming, and farmers often do not dispose of enough time to perform these control measures. Therefore, there is an urgent need for more efficient practices to control this important pest.  The present study evaluated the pathogenicity of two strains of Beauveria bassiana for the control of Monalonion dissimulatum on cocoa: a non-native, commercialized strain (Probiobass MR, Probiotec S.R.L.), and a native strain of Alto Beni, which is not yet commercialized (isolated by the local...

Quantifying resistance and lifestyle assessments of Colletotrichum in lupin
Provedor de dados: 21
Autores: Alkemade, Joris; Messmer, Monika M.; Finckh, Maria R.; Vögele, Ralf T.; Hohmann, Pierre.
Currently Europe imports large amounts of unsustainably produced soy to meet the plant-based protein demand of the feed and food industry. The high protein content and low nutrient requirements of white lupins make them a sustainable local alternative. However, lupin cultivation is severely impaired by anthracnose disease, caused by the seed- and air-borne fungus Colletotrichum lupini. Low levels of seed infestation can already lead to complete yield loss. Understanding the pathogen’s lifestyle and identifying sources of resistance are therefore of major importance to make the re-introduction of white lupin a success. Resistance screening was performed under controlled conditions. Disease severity was scored visually and qPCR was performed on inoculated...

Efficacy of different insecticides and a repellent against the European pear sucker (Cacopsylla pyri)
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The efficacy of different insecticides (neem, pyrethrin, spinosad, and rotenone) and a repellent (kaolin)  applied with different strategies (single or repeated applications) against the over-wintering pear  suckers (Cacopsylla pyri) and nymphs of the first generation was tested in a field trial in Switzerland  in spring 2003.  Rotenone, the only admitted product in Swiss organic agriculture, showed good effects. But, since  Rotenone is toxic for non-target insects we looked for an alternative. The application of spinosad  (Audienz) in combination with rape oil (Telmion) as well as the application of pyrethrum showed  similar efficacy as rotenone. Neem had no or a very low impact on the pear sucker populations. The  repellent kaolin (Surround® WP) showed...

Effect of storage temperature during tuber pre-sprouting on sprout and yield development of organically grown potatoes
Provedor de dados: 21
Autores: Stumm, Chistoph; Neuhoff, Daniel; Koepke, Ulrich.
In the frame of the on-farm-research project ‘Organic Pilot Farms in North Rhine-Westphalia’ (Germany) the influence of different storage temperatures (8, 12, 16°C) during pre-sprouting under full light (&gt; 200 lux) on tuber development was tested. Sprout length and yield development of cultivars Belana and Nicola as affected by the pre-sprouting regime were recorded in five field trials on two sites over three years. Increasing storage temperature during pre-sprouting resulted in significantly longer sprouts at planting. The higher risk of sprout breaking during mechanical planting of seed tubers with longer sprouts was overcompensated by faster crop development. As a function of higher temperatures during pre-sprouting all measured parameters showed...

In Osterreich ist die Nachfrage nach biologisch produzierten Erdbeeren im Steigen. Die im Erdbeeranbau verwendete Hauptsorte Elsanta weist aber eine hohe Anfälligkeit vor allem gegenüber Wurzelkrankheiten (Phytophthora sp., Verticillium sp.) auf. Für den biologischen Landbau ist sie daher nur bedingt geeignet.  Am Markt werden regelmäßig neue Sorten angeboten, für deren Anbau es in Österreich noch wenig praktische Erfahrung gibt. Im vorliegenden Versuch wurden 12 neue und 2 Standardsorten auf ihre Eignung für den biologischen Anbau getestet.

Potential and limitations of plant virus epidemiology: lessons from the Potato virus Y pathosystem
Provedor de dados: 21
Autores: Döring, Thomas F.
Abstract Plant virus epidemiology provides powerful tools to investigate key factors that contribute to virus epidemics in agricultural crops. When successful, epidemiological approaches help to guide decisions regarding plant protection strategies. A recent example is epidemiological research on Potato virus Y (PVY) in Finnish seed potato production; this study led to the dentification of the main PVY vector species and helped to determine the timing of virus transmission. However, pathosystems rarely allow research to produce such clear-cut results. In fact, the notorious complexity of plant virus pathosystems, with multiple interactions between virus, vector, plant and environment, makes them often impenetrable even for advanced epidemiological models....

Effect of two Oat–legumes intercrop systems on weed flora under Mediterranean conditions
Provedor de dados: 21
Autores: Bilalis, Ass. Prof. D.; Konstantas, MSc A.; Efthimiadou, MSc A.; Papatheohari, Dr Y; Kakampouki, MSc I.
The experiments were conducted in Greece in 2002 and 2003. The objective of this research was to investigate i) the effect of intercrop system on weeds and ii) if each intercrop system (oat-pea or cereal legume) is going to affect the weed control differently. The light penetration within the canopy measured during the first experiment (2002), was decreased up to 90%, due to the increase of the companion crops’ leaf area. In both years the decrease of the available light to the weeds, has led to the reduction of the weed dry matter, in comparison to the pure stands. Finally the oat-bean intercrop system gave better results than oat-peas system. As a result we can say that the intercrop system constitutes a new approach to weed control for low input...

Autores: Runno-Paurson, Eve; Tein, Berit; Luik, Anne.
Kartuli kuivlaiksust (Alternaria solani, A. alternata) on seni Eestis peetud suurt kahju põhjustavaks kartulihaiguseks. Viimastel aastatel on kuivlaiksus osutunud  suureks probleemiks Eesti kartulipõldudel, seda eriti just vastuvõtlikel sortidel.  Kuumadel keskmise niiskusega kasvuaastatel on kuivlaiksusele vastuvõtlikel sortidel vaja tavaviljeluses teostada keemilist tõrjet, kuna haigus hävitab enneaegselt  kartuli lehestiku, sageli enne veel kui lehemädanik lööbida jõuab. Kuivõrd maheviljelus välistab keemilise tõrje, siis tuleb leida kasvatustehnoloogilisi võtteid  ning kasutada võimalikult haigusekindlaid sorte.  Uurimustöö eesmärgiks oli selgitada, kuidas erinevad maheviljeluse tehnoloogiad mõjutavad kartuli kuivlaiksuse arengut haigusele soodsal...

Pest and disease management in organic farming: implications and inspirations for plant breeding
Provedor de dados: 21
Autores: Döring, Thomas F.; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
The co-evolution of plants with their pests and diseases is a major driving force in evolution in nature. As a consequence, many pests and pathogens have multiple functions involved in survival on host populations. As a result of this continuous co-evolution, plant pests and pathogens have been selected for high reproduction rates, because of the low probability of an individual being able to find or infect a compatible host plant. For their part, host plants in natural ecosystems are often interspersed among other plant species and show wide and changing variation among individuals for genes affecting specific or non-specific resistance to each of the many pathogens that may attack them. Throughout the plant world there are dynamic and unstable equilibria...

Common bunt is infecting wheat seedling just after sowing, in the heterotrophic phase before seedling emergence. The seed per se is healthy at the time of sowing, but gets infected from spores resting on the seed surface.  Bechel et al. 1998 has shown that only a minor fraction of the spores of the the closely related bunt species T.contraversa in a seed lot end up in the flour, while the majority are removed during the cleaning of the seed before or during milling. However, little is known about the destiny of the spores during the cleaning process of seed intented for sowing.  Seed lots contaminated with bunt spores during threshing was cleaned in a brush cleaner (ø=400mm) (http://www.westrup.com/HAsideeng.htm) with and without precleaning. Airstream...

Aphid (Homoptera: Aphididae) accumulation and distribution near fences designed for cabbage fly (Diptera: Anthomyiidae) exclusion
Provedor de dados: 21
Autores: Bomford, M.K.; Vernon, R.S.; Pats, Peeter.
Aphids accumulate near exclusion fences designed to intercept Delia radicum (L.) movement into fields. Aphid accumulations increase with fence height, but are not affected by fence overhang length. Overall aphid levels are higher in small (4.3 x 4.3 m) enclosed plots than in unenclosed plots. Enclosing large (38 x 38 m) plots does not alter overall aphid catches, but does alter aphid distribution within enclosures. In large enclosures aphid accumulations are higher at enclosure perimeters than interiors, with the highest accumulations near enclosure corners. This concentric distribution is not observed in unfenced areas, and is not altered by the addition of a trap crop inside an enclosure.

Autores: Bauer, Robert; Voit, Benno; Killermann, Berta; Hülsbergen, Kurt-Jürgen.
Steinbrand und Zwergsteinbrand sind bedeutende Krankheiten im ökologischen Landbau. Starker Befall führt zu einem Anstieg des Brandsporenpotenzials im Boden. 3-jährige, randomisierte Fruchtfolgeversuche werden an drei Standorten in vier Wiederholungen auf frisch befallenen Flächen durchgeführt. Die Böden weisen dabei entweder Brandsporen von T. controversa oder von T. caries auf. Es soll im Rahmen des Versuchs überprüft werden, ob durch im ökologischen Landbau übliche Fruchtfolgen das Brandsporenpotenzial im Boden reduziert werden kann. Durch Anbau von Senf als Zwischenfrucht wird getestet, ob durch die Freisetzung von Thiocyanaten und Isothiocyanaten nach dem Mulchen und anschlieβendes Einarbeiten in den Boden eine Abnahme der Sporenzahl im Boden erfolgt....

Provedor de dados: 21
Autores: JIMOH, MUIDEEN; ENIKUOMEHI, OLOLADE; OLOWE, VICTOR; AFOLABI, CLEMENT.
The quest for alternative method in managing diseases in crop production as against the use of prohibitive synthetic chemicals which are harmful to human health has been receiving serious attention by scientists in the last two decades. Two field trials were conducted during the early and late cropping seasons of 2010 to evaluate the effect of nine treatments (Tithonia diversifolia and Chromolaena odorata sprayed at 7.0, 7.5 and 8.0%, sesame sprayed with distilled water, sesame intercropped with maize and sole sesame) on the control of Cercospora leaf spot (CLS) and Alternaria leaf blight (ALB) diseases and agronomic performance of sesame in the transition zone. The experiment was laid out in a randomized complete block design and replicated three times....

Diversification des cultures dans les exploitations maraîchères biologiques : conséquences sur les gestions agronomique et commerciale.
Provedor de dados: 21
Autores: MARGUERIE, Mathieu.
La diversification des productions en agriculture est souvent mise en avant pour ses nombreux intérêts économiques et agronomiques. Ceci est particulièrement vrai en agriculture biologique où les intrants sont très limités et les circuits courts recherchés par le consommateur. L’étude présentée dans ce rapport se concentre sur le maraîchage biologique et sur les formes de diversification des productions au niveau intra-maraîchage et vers d’autres types de productions (céréales, vigne, arboriculture). Ces formes d’organisation sont en effet susceptibles d’accélérer les conversions d’exploitations en France, notamment celles de taille moyenne et importante. Les résultats sont basés sur vingt-cinq enquêtes semi-directives réalisées dans trois départements du...

Bedeutung von direkten Regulierungsmaßnahmen und dem Beweidungsmanagement auf den Besatz mit Ampfer-Arten (Rumex spp.) im ökologisch bewirtschafteten Grünland
Provedor de dados: 21
Autores: Finze, Jana; Böhm, Herwart.
Im ökologisch bewirtschafteten Grünland stellen die Ampfer-Arten ein besonderes Problem dar. Aufgrund ihrer differenzierten Vermehrungs- und Überlebensstrategie können sie bislang nicht effektiv und vor allem nicht nachhaltig reguliert werden. Die Zielsetzung des vorliegenden Projektes besteht in der Evaluierung von bestehenden Strategien zur Regulierung der Ampfer-Arten im ökologisch bewirtschafteten Grünland und der Ableitung von neuen Handlungsempfehlungen. Als Basis dienen sowohl die Ergebnisse aus Versuchen zur Regulierung der Ampfer-Arten auf dem Versuchsbetrieb Trenthorst, als auch der Darstellung der Ist-Situation auf landwirtschaftlichen Betrieben durch eine bundesweite Umfrage.  Die Feldversuche zeigen, dass mit den direkten Regulierungsmaßnahmen...

Welche Bodenzusätze helfen bei der Lösung von Problemen mit Feldaufgang in Spinat?
Provedor de dados: 21
Autores: Meyer, Audrey; Fuchs, Jacques G.; Schärer, Hansjakob.
Damping-off of spinach, caused by soil-borne pathogens, is one of the most serious problems in organic spinach production. To overcome these problems soil amendments based on specific strains of micro-organisms or based on organic material are proposed. In pot experiments under controlled conditions 14 microbial strains and six organic soil amendments were tested on their ability to suppress soil borne diseases and to improve plant stand establishment. In a subsequent field experiment with the best treatments, soil amendments with compost showed the best effect while products based on single strains of micro-organisms failed to improve plant stand establishment. It is concluded that under high disease pressure a diverse population of microorganisms as it...

Provedor de dados: 21
Autores: Atungwu, J. J.; Yusuf, A. O.; Oladeji, O. A.; Aruna, W. O.; Joseph-Adekunle, T. T.; Tijanni, I.
Although fluted pumpkin (Telfairia occidentalis Hook F.) is cherished because of its nutritional, medicinal and industrial values, its profitable production and sustainability in agro-ecosystems is threatened by plant-parasitic nematodes. This study, therefore, tested the hypothesis that Gateway organic fertilizer can effectively suppress herbivorous nematodes while increasing the non-parasitic types. Gateway organic fertilizer (GOF) is one of the series of novel commercial fertilizers being utilized by organic farmers in South-western Nigeria. In this assessment, GOF was applied at the recommended rate of 5 tha-1. Application of 0 tha-1 served as the control. Treatments were laid out in Randomized Complete Block Design and replicated four times. Nematode...

A new visual trap for Rhagoletis cerasi (L.) (Diptera: Tephritidae).
Provedor de dados: 21
Autores: Daniel, Claudia; Mathis, Samuel; Feichtinger, Georg.
The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is the most important pest of sweet cherries in Europe. The aim of our experiments was to develop a new, cost-efficient, lead chromate-free and more eco-friendly trap for monitoring and mass trapping of R. cerasi. Five different-colored yellow panels and three different trap shapes were compared to a standard Rebell® amarillo trap in three experimental orchards in 2012. Trap color F, with a strong increase in reflectance at 500–550 nm and a secondary peak in the UV-region at 300–400 nm, captured significantly more flies than the standard Rebell® amarillo trap. Yellow traps with increased reflectance in the blue region (400–500 nm) were least attractive. Trap shape was of minor...

Disease severity and grain yield of spring barley variety mixtures grown under organic and conventional conditions
Provedor de dados: 21
Autores: Østergård, H.; Kristensen, K.; Hovmøller, M.S.; Jensen, J.W.
Despite quite intensive testing of varieties, predictions of future performance of varieties, when grown on specific locations, are known to be nearly impossible; this especially within organic growing systems, where no pesticides and fertilizers can help stabilize yield. Therefore, using mixtures of appropriate varieties might be a way to obtain more stable and acceptable yields. Variety mixtures have so far been studied mostly under conventional farming conditions and focus has often been to characterize disease progress of one pathogen. Here we consider simultaneously four important foliar diseases on spring barley grown in organic as well as conventional growing systems. Further, we study the changes in disease severity of variety mixtures when...

Nye æblesorter til økologisk dyrkning
Provedor de dados: 21
Autores: Bertelsen, Marianne.
Økologisk dyrkning stiller særlige krav til sortsvalget, som bør bestå af sorter, som er modstandsdygtige over for æblernes mange skadevoldere. I mange år har de professionelle sortsforædlere derfor satset på at udvikle sorter, som er resistente over for æbleskurv, der er den værste svampesygdom på æble. Desværre er skurvresistensen i de seneste år blevet brudt, og de tidligere resistente sorter kan nu angribes af skurv. Det betyder fornyet fokus på at finde egnede sorter til økologisk dyrkning, og det har været et mål for projekt "Fruitgrowth" som har løbet i perioden 2010-2014.

L’agriculture biologique repose sur des apports fréquents de matière organique pour maintenir un bon fonctionnement du sol. Ces apports sont particulièrement importants en cas de reconversion de sol en maraîchage, les sols étant dans ce cas généralement appauvris en matière organique. Avec la raréfaction des ressources en fumier, des composts commerciaux conditionnés en bouchon sont fréquemment utilisés, ainsi que depuis quelques années les composts de déchets verts, économiquement très intéressants mais de composition mal connue.   Une expérimentation conduite sur du moyen terme (8 années) à l’INRA d’Alénya a permis de mieux connaître l’évolution des 2 types de compost fréquemment utilisés en système maraîcher sous abri.

There has been a remarkable scientific output on the topic of how climate change is likely to affect plant diseases in the coming decades. This review addresses the need for review of this burgeoning literature by summarizing opinions of previous reviews and trends in recent studies on the impacts of climate change on plant health. Sudden Oak Death is used as an introductory case study: Californian forests could become even more susceptible to this emerging plant disease, if spring precipitations will be accompanied by warmer temperatures, although climate shifts may also affect the current synchronicity between host cambium activity and pathogen colonization rate.

The cocoa swollen shoot virus disease is a major factor limiting cocoa (Theobroma cacao L.) productivity for West African farmers. The only treatment against this disease is to cut infected trees and replant with disease-free planting material. Research has recommended the prevention measures: (i) cordon sanitaire (leaving 10-m-wide cocoa-free zone around cocoa), (ii) barrier cropping, (iii) using partly tolerant hybrids, and (iv) removing specific alternative host tree species. Here, we evaluate the current adoption of these measures and identify their adoption constraints. We conducted a quantitative survey with 396 farmers in the Eastern and Western Regions of Ghana, held six focus group discussions and hosted a multi-stakeholder validation workshop...

Many growers of organic strawberry and raspberry have large losses in yield and reduced quality of their products because of insect damage. For many insects species pheromones and host plant volatiles are of major importance in mate finding and host plant location. In this project we want to extend our knowledge of these systems to develop effective control measures to control these pests in organic crops. The focus will be on the strawberry blossom weevil, the European tarnish plant bug and the raspberry beetle.

The release of Aphelinus mali HALD. from artificial rearing for the control of Woolly Apple Aphid (Eriosoma  lanigerum HAUSM.) was tested in field trials. The release of adults proved to be more suitable than the release  of cards with parasitized mummies as practised in the first trial. Setting free adult A. mali at the beginning of  June reduced the aphid population, though its efficiency was not high enough to prevent damage of the trees  totally. The practical applications of A. mali in early spring (after blossom) were not effective because climatic  conditions were not suitable enough. The fertility of A. mali depends on temperature and light intensity.  The application of Micula (rape oil) and T-S forte reduced the growth of the aphid population...

Does regional organic screening and breeding make sense?  Experimental evidence from organic outdoor tomato breeding
Provedor de dados: 21
Autores: Horneburg, Dr. Bernd; Becker, Prof. Heiko.
Does regional organic screening and breeding make sense? To answer this question we looked for experimental evidence in an organic outdoor tomato project. Potentially suitable varieties were collected, genotype x environment interactions were investiga-ted and selection was carried out within three crosses at three farms in Central and Northern Germany. The resulting selections were compared at all farms. Screening within organic horticulture was the most important means of finding suitable varieties. After three years of evaluation, 71% of the 18 most successful varieties came from colleagues within organic horticulture. The analysis of the regional evaluation did not reveal strong interactions of varieties and locations. The rate of Phytophthora (late...

FP-7 projektet OSCAR syftar till att utveckla funktionella odlingssystem där marken är täckt av växter under en stor del av året, där den biologiska mångfalden är hög och och där behovet av och mängden jordbearbetning är litet. Föredraget presenterar översiktligt OSCAR-projektet.

New Results from scab-experiments (treatments on fallen leaves and summer-applications)
Provedor de dados: 21
Autores: Pfeiffer, Barbara.
In the leaf-decompositon-trials to reduce the ascospore potential of Venturia inaequalis (2003/2004 and  2004/2005) different agents were tested with regard to direct effects on scab and to increasing the attractivity  of the leaves for earthworms. TSB (lab medium with soya extracts) had a heavy direct effect on ascospore  potential, but in this formulation it cannot be used in organic fruit-growing. Humofix and Bactofil B didn´t reduce  the potential as strongly as in the trial 2002/2003. A yeast extract and a combination of bean extract  with powdered milk increased the attractivity for earthworms. In the trial 2004/2005 the reduction of the ascospore  potential was at best to 60 % of the control (powdered milk+Humofix), respecting the loss by earthworms...

Control of common scab without the use of water
Provedor de dados: 21
Autores: Hilton, A J; Walker, R L; Wale, S J.
The most effective way to control common scab is by irrigating a potato crop at tuber initiation. With the introduction of legislation such as the Water Framework Directive this will become increasingly difficult. In this field experiment, we assessed the potential of a number of non-water measures for controlling this disease. Common scab on daughter tubers at harvest was reduced by applying rapeseed meal at 1 t ha-1 to the beds and then incorporating it into the soil, and adding a mixture of Trichoderma viride isolates into the furrow at planting. None of these treatments was as effective as using water.

Zwiebelproduktion über Steckzwiebeln: Die Qualität des Pflanzguts entscheidet für den Ertrag
Provedor de dados: 21
Autores: Koller, Martin.
Im Bioanbau hat der Anbau von Zwiebeln über Steckzwiebel immer noch eine grosse Bedeutung. Zwar eignet sich die Kulturweise gut für den Bioanbau, da die Unkrautbekämpfung im Vergleich zu anderen Zwiebelanbausystemen einfach ist, aber die Schalenfestigkeit und die Lagerfähigkeit der Zwiebeln aus der gesteckten Kultur ist oft mangelhaft. Ziel der durchgeführten Versuche war, neue und bekannte Sorten auf diese Eigenschaften zu prüfen.  Das FiBL hat in Zusammenarbeit mit Bioproduzenten im Jahr 2005 an zwei Standorten Versuche durchgeführt. Getestet wurden Standardsorten sowie Jetset aus zwei Herkünften, eine neue Sorte und zwei Säzwiebelsorten, die im Vorjahr als Steckzwiebeln produziert wurden.

Entwicklung eines zeitlichen und räumlichen Entscheidungshilfesystems gegen den Erbsenwickler  (Cydia nigricana, Fabricius)
Provedor de dados: 21
Autores: Schieler, M.; Riemer, N.; Racca, P.; Saucke, Helmut; Clemenz, C.; Schwabe, K.; Müller, U.; Hammer-Weis, M.; Kleinhenz, Benno.
Pea moths (Cydia nigricana) can cause severe damages in pea crops (Pisum sativum). Larvae feed on the seeds in the pods and contaminate them with feces. In the cultivation of organic green peas 0.5 % damaged seeds lead to the denial of  whole pea fields (Schulz &amp; Saucke 2005). There can be a yield loss in forage peas and a loss of quality of seeds for propagation. Within the framework of the project to improve the spatial and temporal cultivation strategy of peas to get less damage due to pea moths, is the intention. For  a better spatial and temporal cultivation strategy, the DSS creates a map with areas with an infestation risk factor. The higher the risk factor, the earlier the new fields  should be cultivated. Therefore, the first part of the DSS...

The nitrogen supply plays an important role in achieving quality characteristics in organic potato farming. Different defoliation systems of ryegrass–clover may influence the amount of fixed nitrogen available to the tubers. In a field experiment, the effect of different defoliation systems (cutting, mulching and a combination of them) of the pre-crop ryegrass–clover on selected quality attributes of organically grown potatoes, destined for processing into French fries (cv. Agria) or crisps (cv. Marlen), were conducted in two consecutive years (2003 and 2004).  Parameters studied included compounds related to the sensory properties of potato food (tuber dry matter, starch, reducing sugars) as well as nutritional quality (nitrogen,minerals). Selected...

Breeding for bunt resistance in organic wheat and spelt
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt (Tilletia caries) is one of the most evastating plant diseases, and a particular problem for organic seed production. Organic farming aims at controlling pests and diseases with the use of biodiversity and resistance. However most organic wheat fields today are sown with monocultures of pure line varieties, and resistance to common bunt is rarely used, even this disease causes severe problems for seed producers and for farm saved seed, as infected seed lots are discarded because of contamination with bunt spores. To improve the system, organic wheat needs resistance to common bunt that is effective enough to prevent development of the disease over time. For this reason several initiatives are ongoing to improve bunt resistance in organic wheat...

To increase the yield of organically grown cucumber a lot of investigations were carried out in the last years. The influence of sowing and planting was compared and the susceptibility of different varieties as well as the influence of plant extracts was investigated in field trials. Planting resulted in an earlier harvest with a higher yield. Further effort in breeding resistant varieties with higher yield is needed. Also, the efficacy of plant strengthening products and plant extracts must still be improved. Regulation by specific climate strategy under glass was successful to avoid or delay the infection with Pseudoperonosproa cubensis.

Inokulummängdens betydelse för utveckling av vetets stråbasröta orsakad Fusarium graminearum – Utvärdering av ett biotest
Provedor de dados: 21
Autores: Bertholtz, Erik.
Fusarium graminearum är en av de viktigaste patogenerna på stråsäd och orsakar stora förluster i skörd över hela världen. Den mest odlade stråsäden i Sverige är höstvete. F. graminearum producerar både sexuella och asexuella sporer för spridning. Flera faktorer påverkar produktionen av dessa sporer. Stråbasröta orsakad av Fusarium-släktet är en ekonomiskt viktig sjukdom som kan ge avkastningsförluster på mellan 35% och 61%. I detta försök har ett biotest utvärderats för förhållandet mellan inokulummängd och sjukdomsutveckling hos stråbasröta orsakad av F. graminearum. Sjukdomsindex visade på en tydlig trend med ökande symptom med ökad konidiekoncentration medan torrviktsresultatet inte uppvisade en lika tydlig trend. Biotestet ger ett relativt snabbt...

Beneficials can prevent or reduce outbreaks of pest species. To strengthen the  populations of beneficials, their food sources must be improved in cultivated areas.  The effects of habitat management for augmenting beneficial population on parasitism  and predation rates of three lepidopteran pest species were investigated on two  organic fields in Alten (Switzerland). The aim was to improve pest regulation through  wild flower strips along fields and by planting Centaurea cyanus as companion plant  within the crop. Strips of Centaurea cyanus and Fagopyrum esculentum increased  parasitsm on the lepidopteran pests. C. cyanus planted as companion plant  furthermore increased predation on the eggs and parasitism of the larvae of Mamestra  brassicae. Several...

Plant genomics – a way forward?
Provedor de dados: 21
Autores: Beynon, Jim.
This report was presented at the UK Organic Research 2002 Conference. Diseases of plants cause significant losses in crop yield and quality. Plants contain a battery of genes whose role is to prevent pathogens invading. Their effective use in crop plants is very important in crop production and especially in chemical free cropping systems. Such genes are introduced into crop varieties by plant breeding. The new science of genomics may enable scientists to recognise all the resistance genes present in a plant. This will eventually allow plant breeders to more precisely and rapidly select useful resistant plants in their breeding programmes. Furthermore, genomics could enable effective deployment of these genes in cropping systems, so providing more durable...

Carabid beetles (Carabidae) in agroecosystems - case study on the effects of conversion to organic farming and land structure
Provedor de dados: 21
Autores: Sarapatka, Bořivoj; Vesely, Milan.
Our research compared the effects of farming systems (conventional, conversion to organic farming, resp. organic farming) and land structures (ecotones) on carabid beetles in four experimental plots during a five-year crop rotation cycle. An important factor affecting the composition of carabid communities was the type of land fragmentation contributing to a faster colonization of fields from ecotones. The factor of agricultural management, organic farming, was also significant. In the final years of the experiment we noted changes in the species composition of the carabid communities compared with the first years of the experiment, with an increase in the preference of bigger carabid species. The abundance of large carabid species was much lower in...

Autores: BARBERI, PROF. P.; BIGONGIALI, DR. F.; ANTICHI, DR. D.; CARLESI, DR. S.; FONTANELLI, DR. M.; FRASCONI, DR. C.; LULLI, DR. L.
In organic agriculture, it is important to tackle crop and weed management from a system perspective to make it effective, especially in poorly competitive crops such as vegetables. For that reason, we developed two innovative integrated crop and weed management systems for a field vegetable crop sequence in a commercial organic farm that we have been comparing to a standard farm system from 2006 to 2008. The three systems are applied to a spinach-potato-cabbage-tomato two-year crop sequence and include different levels of technical innovation: Standard Crop Management System (SCMS); Intermediate Crop Management System (ICMS); and Advanced Crop Management System (ACMS). ICMS is based on a sequence of physical weed management treatments, whereas ACMS also...

Knowledge exchange platform for agroecology
Provedor de dados: 21
It offers videos, dossier and short info-sheets reporting practical farmers experiences. At today, for arable crops, it includes a dossiers on direct-drilling in crop residues or living mulches, a dossier on crop association (companion planting) with several details on how to do it in practices and what still needs to be fixed in order to be successful in certain situations, and a dossier on biological control as a tool to manage habitats.  The  language of the platform is very direct and it is easy and fast to use. The platform is a dynamic tool so further material will probably be added in the future.

Einfluss ökologischer Bewirtschaftung und verschiedener Kulturen auf die Regenwurmfauna
Provedor de dados: 21
Autores: Dubois, D.; Jossi, W.; Pfiffner, L.; Tschachtli, R.; Zihlmann, U.
Problemstellung/Ziele:Vorkommen und Artenzusammensetzung der Regenwurmpopulation haben eine grosse Bedeutung im nachhaltigen Ackerbau. Als Architekten und Bauarbeiter des Bodens beeinflussen die Regenwürmer verschiedene Parameter der Bodenfruchtbarkeit und damit das Wachstums der Kulturpflanzen. Der Landwirt beeinflusst das Regenwurmvorkommen bei vorgegebenem Standort und Fruchtfolge vor allem durch Bewirtschaftungsmassnahmen wie Düngung, Pflanzenschutz und Bodenbearbeitung. Um Richtung und Ausmass dieser Einflüsse zu erkennen untersuchten wir von 1997 bis 2001 die Regenwurmpopulationen im ökologischen und den integrierten Anbausystemen des Vergleichsversuches Burgrain (D. Dubois, 1999).    Fazit: Ökologische Bewirtschaftung förderte auf Burgrain...

Den danske dyrkningsjords tilstand og kvalitet - konsekvenser af trafik og jordbearbejdning
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.; Debosz, K.; Mikkelsen, G.H.; Trautner, A.
Et alsidigt sædskifte og/eller tilførsel af organisk stof til jorden giver en god jordkvalitet (her defineret som en gunstig jordstruktur). Ensidige driftsformer kan i sig selv give anledning til en dårlig jordkvalitet. Jordpakning via trafik på jorden kan eliminere de gode effekter af et godt sædskifte og tilførsel af organisk stof.   Trafik på jorden og i endnu højere grad intensiv jordbearbejdning øger risikoen for, at jordens lermineraler dispergeres til vandfasen. Dette kan give tilslemning og skorpedannelse på jorden og indebærer endvidere en risiko for nedvaskning af de vigtige lermineraler fra dyrkningslaget. Der bør foretages undersøgelser af omfanget af denne proces med de i dag anvendte bearbejdningsteknikker.   Komprimering af jorden under...

Spore contamination of Tilletia tritici in seed lots as affected by field disease incidence
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
Seed lots normally become contaminated by spores of the seed borne common bunt (Tilletia tritici) during harvest of fields with infected plants. To demonstrate the relation between the number of infected plants in the field and the resulting number of spores in the harvested seed lot, a fixed number of infected tillers were placed in uncontaminated wheat fields. Two field experiments show   that the number of spores in the seed lot is proportional to the number of infected plants in the field. Only 3% of the spores from the infected plants in the field end up in  the seed lot after harvest with a combine harvester. However, only few spores in a seed lot is enough to establish infection in the next year field, and with a threshold of 10 spores/g seed which...

Autores: Benduhn, Bastian; Krauthausen, Hermann-Josef; Schult, Tina; Toups, Ina; Zimmer, Jürgen.
Ziel des Projektes war es, Möglichkeiten zur Regulierung der Doldenwelke beim Schwarzen Holunder (Sambucus nigra) zu erarbeiten. Dazu wurde zunächst das zeitliche Auftreten der Pathogene erfasst sowie die Erreger bestimmt. In den vier in Nord- und Westdeutschland untersuchten Holunderanlagen wurde die Doldenwelke überwiegend durch Colletotrichum acutatum verursacht. Andere pilzliche Welkeerreger (wie Fusarium sp., Phoma sp.) spielten in den drei Jahren vergleichsweise nur eine untergeordnete Rolle. Vor allem ab Farbumschlag der Beeren stieg der Befall drastisch an. Untersuchungen zur Überdauerung von Colletotrichum acutatum in einer Befallsanlage haben ergeben, dass der Erreger im Dezember an alten Früchten und Fruchtstielen nachzuweisen war. Bei...

Bombus terrestris as an entomovector for suppressing Botrytis cinerea in open field strawberry
Provedor de dados: 21
Autores: Mänd, Marika; Karise, Reet; Muljar, Riin.
Strawberry (Fragaria x ananassa) is a fruit crop grown worldwide, but diseases such as the grey mould Botrytis cinerea frequently limit its yield. Most of grey mould infection on the fruits is initiated during the flowering period. Use of foraging bees as disseminators of microbial control agents (MCAs) to flowers is known as entomovector technology. Many researchers have shown that bumble bees can efficiently vector MCAs; however, most studies have been conducted in greenhouse conditions.

Conference pears; work on system changes to enable better scab  control in organic orchards in the Netherlands
Provedor de dados: 21
Autores: Jansonius, Pieter Jans.
Scab control in Conference pears is the bottleneck in organic growing. A group of growers,  advisers and researchers in the Netherlands is working on new approaches to organic  pear growing. Central to this approach is a reliable and good scab control. Changes in the  system of cultivation are sought which will enable this scab control with less fungicide.  This has become even more urgent since copper was banned as a fungicide in the  Netherlands. First results from trials on vigour control show that there is potency for  system changes that will enable a better scab control in organic growing. Scab incidence  was reduced in three trials with 34, 58 and 82% respectively. The project, in which also  other cultivation measures are being tested, will be...

The mineralization of commercial organic fertilizers at 8°C temperature
Provedor de dados: 21
Autores: Kelderer, M.; Thalheimer, M.; Andreaus, O.; Topp, A.; Burger, R.; Schiatti, P.
In organic production only organic fertilizers and soil conditioners can be used to supply  the soil with nitrogen. The mineralization of these products is slow and so there can be  problems with the supply of nitrogen, when the demand of the plants is high. The supply of  nitrogen from organic products depends on the speed of their mineralization which is  primarily influenced by the composition and formulation of their raw material.  In apple production in the Alps-region especially during spring problems with nitrogen  supply are common. In that period, the weather conditions are sometimes bad, the  temperature in the soil is low and mineralization starts slowly - apple trees demand more  nitrogen than the soil can deliver.  To compensate the demand of...

Das Aroma wird durch flüchtige Verbindungen, die durch metabolische Prozesse in der Pflanze bzw. durch den Verarbeitungsprozess entstehen, hervorgerufen. Für das Aroma gekochter bzw. gebackener Kartoffeln sind besonders die thermischen Reaktionsprodukte von ausschlaggebender Bedeutung. Die Literaturrecherche ergab, dass bislang 159 flüchtige Aromastoffe in rohen Kartoffeln, 182 in gekochten sowie 392 in gebackenen Kartoffeln identifiziert...

Alternative Behandlungsverfahren für die Bekämpfung der Kraut- und Knollenfäule der Kartoffel sowie des Schneeschimmels, des Stinkbrandes und der partiellen Taubährigkeit bei Weizen
Provedor de dados: 21
Pflanzenkrankheiten können mit der Verwendung von gesundem Saat- und Pflanzgut, der Einhaltung einer Fruchtfolge und dem Anbau von wenig anfälligen Sorten, reguliert werden. Für die Erreger der Kraut- und Knollenfäule der Kartoffel (Phytophthora infestans; PI), des Stinkbrandes von Weizen (Tilletia caries; TC) und des Schneeschimmels (Microdochium nivale; MN) trifft dies nur beschränkt zu: MN ist der wichtigste Erreger auf Getreidesaatgut. Er wird durch die Anbautechnik wenig beeinflusst. Der Stinkbrand wurde bisher durch eine beinahe 100%ige chemische Beizung des Saatguts gut kontrolliert, er kann sich jedoch mit der vermehrten Verwendung von ungebeiztem Saatgut wieder leicht ausbreiten. Fusarium graminearum (FG) tritt speziell bei bodenschonendem Anbau...

New Results from scab-experiments  (treatments on fallen leaves and summer-applications)
Provedor de dados: 21
Autores: Pfeiffer, Barbara.
In the leaf-decompositon-trials to reduce the ascospore potential of Venturia inaequalis (2003/2004 and 2004/2005) different agents were tested with regard to direct effects on scab and to increasing the attractivity of the leaves for earthworms. TSB (lab medium with soya extracts) had a heavy direct effect on ascospore potential, but in this formulation it cannot be used in organic fruit-growing. Humofix and Bactofil B didn´t re-duce the potential as strongly as in the trial 2002/2003. A yeast extract and a combination of bean extract with powdered milk increased the attractivity for earthworms. In the trial 2004/2005 the reduction of the asco-spore potential was at best to 60 % of the control (powdered milk+Humofix), respecting the loss by earth-worms...

Wireworm Control using Fodder Rape and Mustard – evaluating the use of brassica green manures for the control of wireworm (Agriotes spp.) in organic crops
Provedor de dados: 21
Autores: Frost, D; Clarke, A; McLean, B M L.
In a field experiment at ADAS Pwllpeiran in 2001, brassica green manures were grown for 6 weeks and dug in before planting King Edward potatoes, to see if they suppressed wireworm in the crop. There was a trend for potatoes grown after mustard to suffer less damage from both wireworms and slugs than potatoes grown after fodder rape or no green manure, but the differences were not significant. Further trials, with longer green manuring periods, are needed to establish if there is a benefit, and whether the breakdown products of brassica green manures are toxic to wireworms.

Autores: Lambion, Jérôme; Raoux, Lucie.
Le mildiou des cucurbitacées (Pseudoperonospora cubensis) est la maladie aérienne la plus grave sur concombre en Agriculture Biologique. L’attaque est souvent foudroyante : concombre et mildiou appréciant tous deux des atmosphères chaudes et humides, il est difficile de jouer sur l’aération des tunnels pour freiner le développement de la maladie. De plus, les moyens de lutte disponibles en AB sont très limités (pas de variétés résistantes, produits fongicides encore peu efficaces et pas encore d'homologation contre le mildiou).   L’objectif de cet essai est :   - de confirmer l'efficacité du soufre mouillable (homologué contre oïdium) : appliqué contre les acariens dans un essai GRAB en 2004, il a montré une efficacité secondaire intéressante contre le...

Nachhaltige Wirkung von Ölrettich auf die Abundanzdynamik von Wurzelgallennematoden im ökologischen Landbau
Provedor de dados: 21
Bei den von pflanzenparasitären Nematoden hervorgerufenen Schäden handelt es sich um ein neuartiges Problem, das im Ökologischen Landbau ein stetig wachsendes Schadenspotential darstellt. Die Ursachen liegen u.a. in zu engen Fruchtfolgen, einem hohen Anteil an Wirtspflanzen (Leguminosen, Gemüse, Hackfrüchte) bzw. einem geringen Anteil an Nicht-Wirtspflanzen (Getreide, Mais) in der Fruchtfolge sowie einer unbefriedigenden Unkrautkontrolle. Zur Zeit ist eine effektive Nematodenregulierung im Ökologischen Landbau nicht möglich.

Autores: Haseli, Andi; Wyss, Eric; Weibel, Franco; Zingg, Daniel.
Einleitung  1997 trat die Blutlaus (Eriosoma /anigerum) in der Schweiz in verschiedenen Bioobstanlagen stark auf. Die Gründe dafür liegen wahrscheinlich in der ungenügenden Parasitisierung der Blutläuse durch die Blutlauszehrwespe. Zwei kalte Winter (1995/96 und 1996/97) aber auch die kühle und nasse Witterung im Mai und Juni 1997 haben die Entwicklung der Zehrwespenpopulationen stark eingeschränkt. Die Schaden waren vielfach enorm und führten nebst Fruchtverschmutzungen zu irreversiblen Trieb- und Knospenschaden, gefolgt von Ernteausfall im Folgejahr, bis zum Absterben ganzer Baume. Die Praktiker begegneten dem Übel mit Mineralölbehandlungen, Entfernung der Kolonien durch Abbürsten bzw. mit einem Hochdruck-Wasserstrahl oder mit viel Geduld für den Aufbau...

In most countries of Mediterranean Basin, Bactrocera oleae (Gmel), the olive fruit fly, is the key pest insect on olives. In Sicily this pest causes losses of fruits and a poor quality olive oil. Many researchers have recently carried out some field studies which were based on the use of kaolin and copper against the olive-fruit fly. In the last years these products have been effective several times in reducing olive fly infestation. Kaolin had, also, some important effect in reducing heat-stress in fruit crops and olive-trees.    The aim of the present study was to assess the effect of kaolin and copper treatment on olive infestations in Sicily and to evaluate chemical and sensory parameters of oils extracted. For this reason, within 2003-2005, the IX...

Autores: Marx, Dr. Peggy; Gärber, Dr. Ute.
Pseudoperonospora cubensis (downy mildew) is an aggressive fungal pathogen of  cucumber. In 2007, glasshouse experiments with organically grown cucumber  (´Airbus`, ´Juliandra`) were performed to investigate the effects of a climate strategy  “conventional” versus “dehumidified” on the development of the downy mildew  epidemic. In both climate strategies the commanding variable for ventilation is the  temperature; in the strategy “conventional” the established set point for ventilation is  22 °C, whereas in the climate strategy “dehumidified” the set point for ventilation  varies from 18 °C to 23.5 °C, depending on the humidity. The results show that the  climate “dehumidified” lowers the occurrence of downy mildew significantly.

Conservation agriculture is arising as an alternative to conventional agriculture with the aim to have a reduced impact on the environment. This includes the use of cover crops to conserve soil quality by limiting soil erosion, adding organic matter, and enhancing soil nutrient content, as well as water availability, which are all factors that can greatly influence the presence of soil organisms. In the current study, we investigated whether winter cover crops can enhance the persistence of entomopathogenic nematodes (EPN) over the winter season. In a first trial we augmented EPN populations in plots without (bared) and with the cover crops, pea (Pisum sativum) or mustard (Brassica juncea). In late autumn, individual mini-plots in each of the three...

Improving disease resistance of pea through selection at the plant-soil interface
Provedor de dados: 21
Autores: Wille, Lukas; Hohmann, Pierre; Messmer, Monika; Studer, Bruno.
Pea (Pisum sativum L.) belongs to the legume family (Fabaceae). Legumes form mutualistic symbiosis with nitrogen fixing rhizobacteria and, thereby, are able to improve soil fertility. Legume crops are important protein source for food and feed and contribute to the nitrogen demand of succeeding crops. Despite their importance, cultivation of cool-season legumes in temperate zones remains below expectations due to low and unstable yields. Soil fatigue is caused by a complex of different soil-borne pathogens and thought to be the main reason for yield losses, especially in pea. Plants have the ability to actively shape the community of root associated microbes through root exudations. Evidence is growing that there is considerable genetic variation for plant...

Multi-dimensional approach against Marssonina coronaria in apple (Abstr.)
Provedor de dados: 21
Autores: Schärer, H.-J.; Ludwig, M.; Oberhänsli, T.; Bohr, A.; Buchleither, S.; Tamm, L.
Marssonina leaf blotch is a fungal disease of apple caused by the ascomycete Diplocarpon mali (anamorph: Marssonina coronaria). The pathogen origins from Asia where it accounts for crop losses of up to 100%. In Europe it was first detected in Italy in 2001 and is spreading since then in Switzerland and southern Germany (first reports in 2010), mainly in organic apple orchards and in orchards for cider production with a reduced fungicide regime. M. coronaria infects the leaves by using appressoria and shortly afterwards forms haustoria in the host cells. Blackish-violet spots appear on the upper leaf side, sometimes turning into star-like lesions. On the lesions acervuli are produced and eventually the leaves become chlorotic and fall off. First symptoms...

Kupferminimierungsstrategien im ökologischen Kartoffelanbau  – Projekt “ÖKO-SIMPHYT“: Erste Erfahrungen aus dem norddeutschen Freiland
Provedor de dados: 21
Autores: Bangemann, L.-W.; Wohlleben, S.; Benker, M.; Kleinhenz, B.; Zellner, M.; Bartels, G.
In the research project „ÖKO-SIMPHYT“ different strategies are tested to reduce the copper application  for Phytophthora infestans in organic potato cultivation. Within the first two years of our research a reduction of the total amount of copper per hectare could be accomplished when applying the new developed forecast system ÖKO-SIMPHYT. With this decision support system a reduction of copper up to 46% was possible, when the infection pressure was relatively low. These first results have now to be proven under high infection pressure conditions. Experiments were carried out in the greenhouse to test the rain stability of copper and contacting agents. It could be proved that precipitation of 30 mm is able to reduce the degree of a copper treatment by up...

Nutzung von Pflanzenextrakten zur Kontrolle der Krautfäule (P. infestans) im ökologischen Kartoffelbau
Provedor de dados: 21
Autores: Neuhoff, D.; Klinkenberg, H.-J.; Köpke, U.
Der Befall mit dem Erreger der Kraut- und Knollenfäule (P. infestans) hat durch frühzeitigen Verlust der Assimilationsfläche regelmäßig erhebliche Ertragsverluste im Ökologischen Kartoffelbau zur Folge. Neben einer Reihe von vorbeugenden Maßnahmen, inbesondere Wahl toleranter Sorten und Vorkeimen des Pflanzgutes (KARALUS 1995, MEINCK 1999), sind zur direkten effizienten Kontrolle derzeit nur Kupferverbindungen zugelassen. Ein weitgehend unerforschtes Potential zur Kontrolle dieses Oomyceten liegt in der Nutzung von Pflanzenextrakten, diese Wirkung wurde in Feldversuchen untersucht.

Autores: Jacob, Irene; Hartmann, Stephan; Schubiger, Franz Xaver; Struck, Christine.
Einleitung und Problemstellung  Anthracnose (Colletotrichum trifolii) hat in den letzten Jahren als Krankheit an Rotklee an Bedeutung gewonnen. Diese Pilzkrankheit kann zu einem erheblichen Verlust von Rotkleepflanzen in Rein- und Mischbeständen mit Gräsern führen. Falls es zu einem vermehrten Auftreten dieser Krankheit auf landwirtschaftlich genutzten Flächen kommt, wäre der Einsatz von Sorten mit einer hohen Resistenz ein vielversprechender Ansatz, um die Grundfutterversorgung, aber auch die Stickstoffversorgung v.a. ökologisch wirtschaftender, viehloser Betriebe abzusichern. Durch die Züchtung von resistenten Sorten spielt die Krankheit bei Rotklee in den USA nur noch eine untergeordnete Rolle. In der vorliegenden Untersuchung sollte geprüft werden, ob...

Organic farming and gene transfer from genetically modified crops
Provedor de dados: 21
Autores: Moyes, Catherine L.; Dale, Philip J.
This is the final report of MAFF/Defra project OF0157.    Genetically modified (GM) crops cannot be released into the environment and used as food, feed, medicines or industrial processing before they have passed through a rigorous and internationally recognised regulatory process designed to protect human and animal health, and the environment.      The UK body that oversees standards in organic farming, the United Kingdom Register of Organic Food Standards (UKROFS), has ruled that genetically modified (GM) crops have no role to play in organic farming systems. They, therefore, have concerns about the possibility and consequences of the mixing of GM crops with organic crops.      The two main sources of mixing are through pollen and seed. Pollen from GM...

Determining the effect of organic and low-input production methods on food quality and safety. QLIF subproject 2: Effects of production methods
Provedor de dados: 21
Autores: Leifert, C.
The objectives of QLIF subproject 2 were to: (i) identify the effect of production systems (organic, low-input and conventional) on food quality and safety parameters; (ii) identify agronomic parameters responsible for differences in food quality and safety; (iii) carry out a pilot study into the effect of consumption of organic crops on hormonal balances and immune status in a model experimental animal system. The results showed that organic food production methods resulted in: (a) higher levels of nutritionally desirable compounds (e.g., vitamins/antioxidants and poly-unsaturated fatty acids such as omega-3 and CLA); (b) lower levels of nutritionally undesirable compounds such as heavy metals, mycotoxins, pesticide residues and glyco-alkaloids in a range...

Breeding is an important tool to develop varieties with an optimal adaptation to organic farming. Several important traits are not covered by conventional research and breeding. At the State Plant Breeding Institute we are presently working on (1) resistance of rye to ergot (Claviceps purpurea), (2) nitrogen(N)-use efficiency in triticale, and (3) protein content of sunflower. The inheritance of these complex traits is quantitative. They are analysed in replicated field experiments at two locations in three years at several organic farms in Germany. For testing ergot resistance in rye, 68 populations, 250 full-sib families, 64 lines, and their 90 testcrosses were inoculated at mid-flowering by a spore suspension.

Marker assisted breeding and mass selection of wheat composite cross populations
Provedor de dados: 21
Autores: Steffan, Philipp; Borgen, Anders; Lazzaro, Mariaterresa; Backes, Gunter; Rasmussen, Søren Kjærgaard.
Utilising diverse populations instead of single line varieties is expected to lead to a number of advantages in cereal production. These include reduced epidemics of plant diseases, improved weed competition and better exploitation of soil nutrients, resulting in improved yield stability. However, a number of challenges must be met before diverse wheat populations can be introduced into commercial wheat production: one of these is the development of breeding technologies based on mass selection which enable breeders and farmers to improve specific traits in populations and maintain diversity at the same time.

Composition of variety mixtures in barley and wheat
Provedor de dados: 21
Autores: Østergård, H.
Breeding within the last 50 years has focused on developing genetic uniform crops/varieties for farmers to be able to produce homogeneous products to be sold. Therefore, especially for selfing crops like wheat and barley where nearly all plants in a field are genetical identical, specific tools have to be applied to ensure genetic diversity. Among these tools is the use of variety mixtures. Principles for composing variety mixtures are to a large extent based on disease resistance characteristics and this is insufficient to predict the performance of the mixtures. Biological principles for interactions between varieties will be of relevance not only to organic farming but also to conventional agriculture where variety mixtures have been used for many years...

En agriculture biologique, les moyens de protection contre les ravageurs aériens sont coûteux et leur efficacité est parfois insuffisante. La pratique des brumisations sous abris réduit les températures et augmente l’hygrométrie, et peut améliorer la protection contre l’acarien Tetranychus urticae, comme l'ont montré les essais du GRAB conduits de 2002 à 2004 sur melon, aubergine et concombre. Cet essai a pour objectif d’étudier l’intérêt de la brumisation et de la lutte biologique contre l'ensemble des ravageurs aériens sur tomate : acariens, aleurodes, pucerons, thrips.

Migration und Ausbreitung der Kirschfruchtfliege innerhalb von Obstanlagen – Möglichkeit der biologischen Bodenbehandlung
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The European cherry fruit fly (Rhagoletis cerasi) is the only pest insect which makes a  insecticide treatment of cherry fruit necessary. With regard of residue free cherries a biocontrol  method for R. cerasi by soil applications seems attractive. However, soil treatments can only be  effective if the migration of flies is low. In order to examine the potential of soil treatments and to  understand the dispersal behaviour of R. cerasi in orchards, experiments using nettings to cover the  soil were conducted. The experiments were arranged in commercial, organically managed orchards. The nettings reduced fruit infestation by 90%. In addition, it was shown that the flies move only very short distances (less than 5 m) within orchards. Thus, soil treatments...

Genetic potential for grain yield in spring barley varieties and variety mixtures in variable organic environments
Provedor de dados: 21
Autores: Østergård, Hanne; Kristensen, Kristian; Hovmøller, Mogens; Willas, Jakob.
For organic crop production, well-characterised varieties increase the possibilities for controlling diseases and weeds and compensating for deficits in nutrients. Variation in grain yield was studied in about 150 spring barley varieties and variety mixtures and 20 combinations of location, growing system and year. Choice of variety was found to be as important a factor for grain yield as other factors in the management. Some variety mixtures out yielded even the best variety in the mixture, when this was grown in pure stand. Finally, a concept for organic variety testing of spring barley was developed. This Danish project is part of a European COST Network on sustainable low-input cereal production (SUSVAR) which coordinates studies in different countries...

Die Versuche unter norddeutschen Praxisbedingungen sowie die Ergebnisse der Feldversuche belegen eine durchgehend höhere Attraktivität des Rübsens gegenüber Raps für den Rapsglanzkäfer. Damit werden die Beobachtungen aus der Praxis zunächst bestätigt. Durch den direkten Vergleich von Rapsfeldern mit und ohne Rübsen-Randstreifen sowie von Raps/Rübsen-Mischsaaten mit Rapsreinsaat in Praxis- sowie Feldversuchen war es möglich, den Erfolg dieser Maßnahme in seiner gesamten Wirkungsvielfalt zu untersuchen.  Es hat sich gezeigt, dass entgegen den Erwartungen weder der Schädlingsbesatz noch der Schaden im Rapskernbestand durch den Rübsen-Fangstreifen wesentlich reduziert werden konnte.

Results in research on lime sulphur and other products to control apple scab under northern German climate conditions
Provedor de dados: 21
Autores: Klopp, Karsten; Kruse, Petra; Maxin, Peter; Palm, Gerd.
In 2003 six apple scab control strategies were tested, three with only lime sulphur in  different application strategies, another three strategies with different amounts of  copper. The strategies were tested in an organic apple orchard near Hamburg,  Germany, on a 15 year old `Elstar´ plantation. Due to the recorded infection periods  and the infection load the different strategies were tested. The results show that a  proper lime sulphur strategy is quite successful to fight apple scab (&lt; 4% infected  fruit), has good side effects on apple mildew (&lt; 2%) and only little russetting (&lt; 5%)  compared to strategies with copper fungicides. ablto fight fruit scab as well as leave  scab. A proper strategy means no application later than 15 hours after...

Potatisbladmögel, fältinventering av olika smittkällors betydelse
Provedor de dados: 21
Målet är att undersöka vilka källor till primärinokulum av Phytophthora infestans som finns och vilken roll de har för starten av bladmögelepidemier i Halland och nordvästra Skåne. Fördjupade kunskaper om de huvudsakliga källorna till epidemierna är grundläggande för att utarbeta praktiskt användbara handlingsprogram som kan hjälpa lantbrukarna att nå hög kvalitet och hög kvantitet i ett långsiktigt perspektiv.        Projektet kommer att genomföras i huvudsak genom en inventering. Syftet är att inventera de tidigaste angreppen i området och provta dem för att analysera om det rör sig om ett primärangrepp och av vilken karaktär angreppet är.

The identification and production of varieties that increase the value of oats as a profitable component of organic production
Provedor de dados: 21
Autores: Clarke, S M; Haigh, Z; Hinchsliffe, K E; Jones, H E; Wolfe, M S.
Two experiments, one comprising husked, and the other naked, oats were established at Wakelyns Agroforestry, Suffolk in October 2004 to determine traits and varieties of oats suited to organic systems, and whether growing variety mixtures conferred any advantage. Unselected F2 breeding lines were also included for selection. Husked varieties had relatively higher yields; this may have been partly the result of poor establishment in the naked varieties. Variety height was found to be an important characteristic; tall oat varieties out-yielded the dwarfs. Two of the three variety mixtures containing the naked oat variety Expression yielded 8 and 9 % higher than the average of the component varieties. The data will be verified in the second year of replicated...

Strawberry blossom weevil (SBW), Anthonomus rubi Herbst (Coleoptera: Curculionidae) and European tarnished plant bug (ETB), Lygus rugulipennis Poppius (Hetereoptera: Miridae), cause significant damage to strawberry and raspberry crops. Using the SBW aggregation pheromone and ETB sex pheromone we optimized and tested a single trap for both species. A series of field experiments in crops and seminatural habitats in five European countries tested capture of the target pests and the ability to avoid captures of beneficial arthropods. A Unitrap containing a trapping agent of water and detergent and with a cross vane was more efficient at capturing both species compared to traps which incorporated glue as a trapping agent. Adding a green cross vane deterred...

Bladsygdomme på byg afhænger af sort, placering i sædskiftet og gødningstype
Provedor de dados: 21
Autores: Hovmøller, M.S.; Berntsen, J.; Thomsen, I.
Plantesygdomme i økologisk planteproduktion har stor indflydelse på produktkvalitet og udbytte. Specielt i korn er der gode muligheder for at forebygge svampesygdomme ved hjælp af sortsresistens, idet mange års planteforædling har bidraget til at øge niveauet af resistens mod de mest betydende svampesygdomme. Dette gælder bl.a. resistens mod bladsvampe som meldug, bygrust, skoldplet og forskellige bladpletsvampe.    En sorts resistensniveau mod en given svampesygdom er imidlertid ikke konstant, men kan ændre sig over tid og have forskellig effekt i forskellige dele af landet. Det skyldes primært forskelle og dynamik i de patogenpopulationer, som forårsager de pågældende sygdomme. Derudover er sygdomsniveauet i den enkelte mark afhængig af det lokale...

Susceptibility of Rhagoletis cerasi to entomopathogenic fungi
Provedor de dados: 21
Autores: Daniel, Claudia; Keller, Siegfried; Wyss, Eric.
The effects of six fungus strains (Deuteromycotina: Hyphomycetes) on the mortality of different life stages of the European cherry fruit fly, Rhagoletis cerasi Loew (Diptera: Tephritidae), were assessed in a series of laboratory experiments. All fungus strains were able to cause mycosis to larvae and adults of R. cerasi. However, virulence varied considerably among the strains. Effects on  L3-larvae were negligible. In contrary, adults were highly susceptible to fungus infection. Beauveria bassiana and Paecilomyces fumosoroseus caused 90 to 100% mortality and had a strong influence on fecundity. Metarhizium anisopliae also showed reliable effects. The pathogenicity of Paecilomyces farinosus was low. Higher conidia concentrations lead to higher mortality,...

Fruit quality of Elstar en Santana in the Netherlands

Autores: Jansonius, Pieter Jans.
The growth of the market for Dutch organic apples is disappointing. Especially the large-scale introduction  in the supermarket channel is not happening as fast as many hoped. One of the explanations  given is that there is a gap between the quality as produced and the quality as expected by the  retailers. In a three year project the Louis Bolk Institute together with many other partners in the  sector have tried to facilitate talks on apple quality between actual partners in the different chains  from producer till retailer. During this period we monitored the quality of Elstar and Santana on  many farms and on the shelf in the different outlets. This has given us detailed information about  the current quality of Dutch organic apples. Presented here are...

Final report for the CORE Organic Plus funded project “Innovative design and management to boost functional biodiversity of organic orchards EcoOrchard”
Provedor de dados: 21
Orchards are perennial cultures, and especially in organic fruit production it is essential to design and manage orchards in a way which favours predators and parasitoids over pests. Increasing plant biodiversity and habitats in such a way that beneficials are favoured is called Functional (Agro-)Biodiversity (FAB). The value of FAB for reducing pesticide use in fruit production is generally acknowledged, and many organic fruit growers try to increase it in spite of a shortage of information on FAB, economical and technical challenges and lack of situation-specific, detailed advice. To improve this situation, ECOORCHARD combined several complementary and goal oriented approaches: i) identifying and compiling still “unknown” methods already implemented by...

Wheat/forage legume intercropping in organic grain system: an answer to both weed and nitrogen deficiency issues
Provedor de dados: 21
Autores: Amosse, Camille; Celette, Florian; Jeuffroy, Marie-Hélène; David, Christophe.
Organic grain system managers have to find solutions to nitrogen deficiency and weed infestation. It is especially true when no animals are present on the farm to justify the use of forage legumes despite their interests in the crop succession. Our study focused on the role of four legume cover crop species inserted in a succession of winter wheat and maize on both problems. This insertion consisted in relay-intercropping the legumes under the canopy of wheat. Cover crops were maintained on the field after the harvest of the cereal until the sowing of the subsequent maize crop. The performance of the three crops of the succession was monitored as well as weed development and nitrogen dynamic in the soil-plant system. On the one hand, our results showed...

Overskridelse af den nuværende tærskel af 15% frøsmitte vil formodentlig kun i modtagelige sorter som Lux og Prestige give anledning til høje bladpletepidemier og dermed højt risiko for høje udbyttetab. Mit forslag er derfor: tærsklerne sættes ned (5%) for sorter i PVO gruppe 3, tærsklerne bliver som de er (15%) for sorter i PVO gruppe 2, tærsklerne sættes op for sorterne i PVO gruppe 1 (25%); tærsklerne er ikke nødvendige for sorter i PVO gruppe 0. (Faktisk vil man i praksis sandsynligvis ikke kunne finde 25% frøsmitte i sorter i PVO gruppe 0 og/eller 1.)

Quote from the article    "Potassium phosphite, also called «phosphonate», is a salt of phosphonic acid with the formula K2HPO3.    It should not be confounded with phosphates, nor with the organophosphorous insecticides which are also called «phosphonates». Potassium phosphite can be used as a fungicide against oomycetes in various crops. In the early 1990ies, it was extensively tested on organically grown grapevines in Switzerland. It was effective against downy mildew (Plasmopara viticola), and blocked the disease up to 3 days after infection. Phosphite was mobile and very persistent in plants and could be detected in grapes harvested one year after the last application. Analyses of 53 wine samples reveiled that the treatment inevitably leads to...

Significance of seed-borne Ascochyta on pea and test of management strategies
Provedor de dados: 21
Autores: Wolffhechel, H.; Bødker, L.; Nielsen, G.C.
Large amounts of Danish pea seeds are rejected each year due to high levels of Ascochyta infections. Selection of less susceptible pea varieties may reduce seed infections, while intercropping with barley only gives a small reduction. Increasing seeding rates has no effect.

How to improve disease control in European organic viticulture
Provedor de dados: 21
Autores: Rossi, Vittorio; Legler, Elisabetta.
Organic agriculture and, in particular, organic viticulture have grown considerably in the last decade, nonetheless organic farming still has a huge potential for innovation and improved solutions. The research project VineMan.org (www.vineman-org.eu) aims at improving disease control, which is one of the main and most difficult tasks in oganic viticulture, by integrating plant resistance against fungal pathogens, vineyard management practices, and the use of biological control agents according to optimized outbreak forecasting systems.

Samspel mellan skadedjur och deras naturliga fiender i ekologiskt odlade äpplen
Provedor de dados: 21
Syftet med projektet är att etablera en baskunskap om mekanismerna för samspelet mellan skadedjur och deras naturliga fiender i äppelodling. Denna kunskap kan sedan användas för utveckling av en strategi för förbättring av den naturliga biologiska bekämpningen av skadedjur i odlingssystemet. Till exempel genom att öka de naturliga fiedernas födoresurser och förbättra deras övervintringsförhållanden. Projektet fokuserar på två fjärilslarver, rönnbärsmalen (Argyresthia conjugella) och äpplevecklaren (Cydia pomonella), som båda gör skada på äpplen i form av gångar i fruktköttet. Först görs inventeringar i fält för kartläggning av skadedjurens olika utvecklingsstadiers fenologi. Under samma tid identifieras de naturliga fienderna och deras fenologi. De två...

Suivi et étude des viroses et maladies similaires (phytoplasmoses) courantes et émergentes de la vigne en Suisse, sélection sanitaire virologique, miase à jour et développement de méthodes et de réactifs diagnostiques et de moyens de lutte
Provedor de dados: 21
Plusieurs dizaines de virus, viroïdes et phytoplasmes infectent la vigne et certains de ces agents entravent la croissance et la productivité des ceps ou ils diminuent la qualité du vin. La multiplication végétative et le greffage créent des conditions particulièrement favorables à la dissémination massive de ces infections. Par manque de traitements chimiques contre ces maladies, la lutte se limite principalement à l'utilisation de plants rigoureusement sélectionnés, exempts des principaux virus et agents similaires. Par manque de produit homologué, la lutte chimique contre les nématodes vecteurs des virus associés à la dégénérescence infectieuse (court-noué) n'est pas non plus possible. La sélection sanitaire du plant requiert des moyens de diagnostic et...

Efficacy of biological insecticides to control the Colorado potato beetle (Leptinotasara decemlineata) in organic farming
Provedor de dados: 21
Autores: Kühne, Stefan; Reelfs, Torben; Ellmer, Frank; Moll, Eckard; Kleinhenz, Benno; Gemmer, Christine.
The Colorado potato beetle (Leptinotasara decemlineata Say) is one of the most important pests on potatoes (Solanum tuberosum). In the present study, we compared the efficacy of three biological insecticides – Neem (NeemAzal-T/S), pyrethrum/rapeseed oil (Spruzit Neu) and Bacillus thuringiensis var. tenebrionis (Novodor FC) – against this pest in field trials conducted from 2005 to 2007. The combined and temporarily shifted application of neem and B.t.t. reduced significantly the number of beetle larvae and the percentage of defoliation due to larval feeding, and increased the potato yield considerably. The SIMLEP3 forecasting model is useful for determining the optimal timing of the treatment. Pyrethrum/rapeseed oil did not lead to a significant reduction...

Autores: Cahenzli, Fabian; Daniel, Claudia.
Im Sommer 2016 wurde an der Weinsorte Cabernet Cortis in Elfingen ein Versuch angelegt, um die Wirksamkeit von Nekapur (Löschkalk, Calciumhydroxid) und dem Versuchsprodukt N-2015 gegen die Kirschessigfliege Drosophila suzukii zu testen.  Aufgrund des geringen Befallsdruck konnte im Versuch lediglich eine geringe Eiablage im Rebberg festgestellt werden. Es konnten keine Nebenwirkungen der geprüften Mittel auf Nichtzielorganismen gefunden werden. Aufgrund der niedrigen Anzahl an Nichtzielorganismen in der unbehandelten Kontrolle, kann dazu jedoch noch keine abschliessende Aussage getroffen werden.  Neben den Erhebungen im Freiland wurden neun Tage nach der letzten Behandlung Beeren geerntet, die im Labor in Fliegenkäfigen exponiert wurden. Die Spritzmittel...

Rhizosphere microbiome and disease resistance - Project presentation
Provedor de dados: 21
Autores: Hohmann, Pierre; Wille, Lukas; Studer, Bruno; Messmer, Monika.
Disease resistance is not a mere plant but a system trait involving the complex plant-associated microbial community (Berendsen et al. 2012). As with pathogens, past research often focussed on single, culturable symbiotic microbes. More recently, microbial shifts on the community level have been linked to disease resistance. However, simplistic statements such as “high microbial diversity equals healthier plants” were not confirmed in most recent microbiome analyses (Hartmann et al. 2014, Yu et al. 2012). Plants have the ability to influence the microbial structure in the rhizosphere. Besides soil type, it has been demonstrated that not only different plant species, but also different genotypes within the same species can modify the rhizosphere microbiome...

Provedor de dados: 21
Autores: Bauer, Andrea; Sedlmeier, Monika; Killermann, Berta; Voit, Benno.
Mit Hilfe neuer Untersuchungsmethoden ist es in einem Forschungsprojekt erstmals gelungen, das Brandsporenpotential von Steinbrand (Tilletia caries)- und Zwergsteinbrand (Tilletia controversa) im Boden quantitativ zu erfassen und zu bestimmen (Dressler et al.  2011). Bei Zwergsteinbrand ist seit langem bekannt, dass neue Infektionen vom Boden aus erfolgen. Bei Steinbrand konnte dies erstmals nachgewiesen werden. Mit Feldversuchen auf Öko-Flächen, die ein hohes Sporenpotential aufweisen, soll anhand verschiedener Fruchtfolgen untersucht werden, ob unterschiedliche Bewirtschaftungen die Infektionsfähigkeit der Sporen beeinflussen. Es werden zum einen sehr gegensätzliche Bewirtschaftungen, wie offengehaltene Brache- und ständig bewachsene Kleegrasflächen...

Effect of alternative seed treatments on seed-borne fungal diseases in tomato
Provedor de dados: 21
Autores: Kasselaki, A. M.; Malathrakis, N. E.; Goumas, D. E.; Leifert, C.
The fungus Didymella lycopersici infects tomato seed and results in great losses before and after germination. To control the disease, seed companies use thiram preventively, although human allergy problems have been reported. For this reason as well as to address needs in organic agriculture, this study has focused on the effects of alternative methods of control. Nitrite solutions and resistance inducers were tested in a growth chamber. Results showed that soaking the seed in a nitrite solution with a concentration of 300mΜ (in citric acid buffer, pH 2) for 10 minutes reduced losses due to low seed germination and disease incidence in the germinated seedlings completely. When applied for longer intervals sodium nitrite proved phytotoxic whereas in...

Biologische Bekämpfung von Rhizoctonia solani im ökologischen Anbau mit Hilfe von bakteriellen und pilzlichen Antagonisten
Provedor de dados: 21
Autores: Grosch, Rita; Lottmann, Jana; Faltin, Franziska; Berg, Gabriele.
Rhizoctonia solani Kühn ist ein weit verbreiteter bodenbürtiger Erreger, der an verschiedenen Kulturen für ökonomisch relevante Ertragsverluste verantwortlich ist. Der Erreger R. solani ist aufgrund seiner sowohl saprophytischen als auch parasitischen Eigenschaften sowie seiner persistenten Dauerorgane (Sklerotien) schwer zu bekämpfen. Seine Fähigkeit auch an Nichtwirtspflanzen seinen Lebenszyklus vollenden zu können, erschwert die Kontrolle über Fruchtfolgen, die insbesondere im organischen Landbau Teil der Bekämpfungsstrategie gegen bodenbürtige Erreger sind. Probleme durch R. solani treten im ökologischen Anbau vor allem an Kartoffeln auf. Derzeit stehen dem ökologischen Anbau keine geeigneten Strategien zur Bekämpfung des Erregers zur Verfügung. Ziel...

Autores: Brandt, Kirsten; Ejlersen, Astrid; Nørbæk, Rikke; Lindhard Petersen, Hanne.
Apples were grown with 3 different alleyway groundcover management strategies, providing a wide range of nutrient availabilities to the trees, spanning the ranges normally found in both conventional and organic orchards. These treatments had significant effects on both yields and incidence of fungal diseases. However, the differences in yields and disease incidence cancelled each other out, resulting in identical average yields of marketable fruit, as reported earlier (Lindhard Petersen &amp; Bertelsen 2002).     These results indicated that the composition of the fruit may also differ, and that this material is useful as a model for investigating how growth conditions influence the content of nutritionally relevant compounds, and thus may affect the...

In future the current molecular methods will be improved, validated and  automated, making it possible to use them in the routine identification, detection and  quantification of Fusarium species for e.g. resistance studies. Molecular analyses  require expensive equipment, but they allow quicker and more reliable identification  with fewer people than traditional morphological identification. Internal standards  should also be used in future to discriminate between uninfected samples and possible  PCR inhibition (Waalwijk et al., 2004). The computer analysis of molecular data is also  expected to improve and the total amount of sequence data in the databases will  increase. The whole genome of F. graminearum, for instance, has already been  sequenced...

Autores: Häseli, Andreas; Zingg, Daniel.
Since reduction in effectivity of the bitter wood preparation Quassan in the years 1999 and 2000, the quality of the product had to be criticised. Quality control has since been improved, in so far as each batch is now tested in a biotest on aphids before dispatch. Parallel to its normal use in the field, the effect of Quassan was also field tested in 2001 against apple sawflies. Quassan was tested in different concentrations per hectare and the effect compared with an untreated control as well as with plots treated with a self-cooked Quassiawood extract. All the methods showed an efficacy of 80% or more as compared with the control. Differences due to concentration per hectare used were only minimal.

Introduction: For many insect species, pheromones and host plant volatiles are of major importance in mate finding and host plant location. Therefore, there is potential for using these interactions to develop new strategies and effective control measures. The strawberry blossom weevil (Anthonomus rubi), the European tarnished plant bug (Lygus rugulipennis) and the raspberry beetle (Byturus tomentosus) cause large losses (10-&gt;80%) in both conventional and organic strawberry and raspberry production. We investigated whether the natural semiochemical mechanisms of these key pests can be exploited to develop effective traps for their management through mass trapping.  Methods: Attractive traps and lures with host plant volatiles and pheromones were...

Organic breeding should select for plant genotypes able to efficiently exploit indigenous Probiotic Rhizobacteria
Provedor de dados: 21
Autores: Bosco, M.; Baruffa, E.; Picard, C.
In order to rapidly achieve crop varieties adapted to organic crop production systems, it is of crucial importance to know plant genotype potential for positive interactions with soil indigenous microflora. In this frame, European research efforts are now considering beneficial non-symbiotic (probiotic) rhizobacteria as an essential factor for sustainable plant breeding. Published findings are beginning to elucidate how probiotic rhizobacteria contribute to plant nutrient assimilation and disease resistance. Future efforts for crop breeding in organic agriculture should take into the right account the capacity of plants to efficiently exploit indigenous probiotic rhizobacteria in low-input cultural conditions.

Effect of Rapid or slow release nitrogen supply and cover crop/weed management on crop yield, pest incidence and fruit quality in intensive organic apple production
Provedor de dados: 21
Autores: Lindhard Pedersen, H.
Apple is the commercially most important top fruit crop grown in the European Union.   In spring 2001 one-year-old trees of the apple variety ‘Ingrid Marie’ were established in an organic production system with 3.0 m between the tree rows. Each plot consisted of three semi-plots at planting distances 0.6m (5555 trees ha-1), 0.9 m (3333 trees ha –1) and 1.2 m (2777 trees ha-1). Tree growth, soil moisture, soil-, leaf- and branch analysis, diseases, fruit production, outer and inner fruit quality were measured.  The healthiest trees with the best coloured fruits were produced on trees grown in weed. But the yield was so low that production was not economical. A high production combined with trees less infected with fruit tree canker and with a satisfactory...

Einsatz suppressiver Grünabfallkomposte zur Kulturstabilisierung gegenüber bodenbürtigen Krankheiten im ökologischen Gartenbau
Provedor de dados: 21
Autores: Bruns, Christian; Waldow, Franziska; Schüler, Christian.
Suppressive Effekte von Komposten sind für eine ganze Reihe von unterschiedlichen Kompostarten beschrieben worden. Dazu gehören Komposte aus der getrennten Sammlung organischer Abfälle. Insbesondere Grünabfallkomposte aus Baum- und Strauchschnittsammlungen verfügen über vorzügliche Qualitäten, da sie in Substraten für gärtnerische Kulturen wegen ihrer geringen Salz- und Nährstoffgehalte besonders gut einzusetzen sind. Grünabfallkomposte zeigen fungistatische Effekt gegenüber Erregern aus der Klasse der Oomyceten. Vielfach wiesen die Komposte hohe Anteile von potentiellen Antagonisten auf (Pseudomonas spp., Trichoderma spp. Actinomyceten) und zeigten hohe mikrobielle Aktivitäten, die eng mit den suppressiven Effekten korreliert haben. Die bisher vor allem...

Sortenanfälligkeit von interspezifischen Rebsorten für Drosophila suzukii
Provedor de dados: 21
Autores: Daniel, Claudia; Matray, Silvia.
Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa eingeschleppt und verursacht seitdem z.T. massive Ertragsausfälle. Sie befällt alle Weichobstarten,wie z.B. Beeren, Kirschen, Zwetschgen und Trauben. Auch viele wilde Pflanzen, wie z.B. Holunder und Schneeball dienen als Wirtspflanzen. Der Hauptschaden entsteht durch den Larvenfrass an den Früchten. Da der Generationszyklus sehr kurz ist und daher mehrere Generationen parallel auftreten, kommt es zu einem starken Befallsdruck im Spätsommer und Herbst. Da Weinreben länger hängen als z.B. Beeren und die Lese erst im Herbst stattfindet, ist in Reben mit einem besonders hohen Befallsdruck zu rechnen. Aufgrund der Witterungsbedingungen wurden in der Schweiz im Jahr 2014 erstmals...

Control strategies for late blight in organic potato production
Provedor de dados: 21
Autores: Zarb, John; Ghorbani, Reza; Juntharathep, Pintip; Shotton, Peter; Santos, Joanna; Wilcockson, Steve; Leifert, Carlo; Litterick, Audrey M; Bain, Ruaridh A; Wolfe, Martin.
This report was presented at the UK Organic Research 2002 Conference. Protective copper fungicides are currently used to control late blight in most organic production systems, but approval for their use in organic farming will be revoked in 2002. Evidence suggests that organic potato production will not be reliably economic in the absence of Cu. Current controls for late blight are reviewed including: variety selection/breeding for blight resistance, diversification strategies, agronomic strategies for the management of late blight, and alternative treatments to Cu-fungicides.

Meta-analysis is a powerful tool to summarize variety mixture effects - exemplified by grain yield and weed suppression of spring barley
Provedor de dados: 21
Autores: Kiær, Lars; Skovgaard, Ib; Østergård, Hanne.
In a new project, we aim to increase the general understanding of the power of meta-analysis to combine existing experimental results on variety mixtures. In this way, explanatory power can be increased compared to separate analyses and overall measures and relationships may be revealed. We will thus pursue to uncover a number of critical issues, including the relative importance of various traits and trait combinations on mixing success. To demonstrate the methods of meta-analysis applicable for variety mixture data, we considered a data set consisting of grain yield and weed ground cover assessments in 16 field trials of six 3-component variety mixtures and their components (part of the Danish BAR-OF field trials). The effects of mixing were analysed...

The use of organic certified compost to control soilborne diseases caused by Phytophthora spp.
Provedor de dados: 21
Autores: Pugliese, Massimo; Gullino, M. Lodovica; Garibaldi, Angelo.
Soilborne pathogens can cause serious damages to economically important crops. Control of these diseases has traditionally depended upon rotations and soil quality improvement strategies. Compost has shown a suppressive activity against soilborne pathogens, and its use may decrease the severity of root rot diseases, optimize waste recycling and increase yields in organic farming. An organic certified compost produced from biowaste, green and yard wastes in a composting plant in the North-West of Italy, has been analysed for its suppressiveness against Phytophthora disease. The organic certified compost has been compared with a conventional compost produced in the same composting plant and with a peat substrate. In the first  group of trials, composts...

EFFECT OF DIFFERENT ECOLOGICAL ENVIRONMENTS ON ORGANIC CULTIVATED SOYBEAN (Glycine max (L.) Merril.)
Provedor de dados: 21
Autores: Borbélyné Hunyadi, Éva.
In recent years different protein sources have gained importance. Crop cultivation plays an important role in meeting the demand for many of these. In order to improve the quantity and the quality of yields; we must acquire a complex ecological attitude and exercise a more rational use of natural resources. To succeed requires favourable material, technical and social circumstances. The exploitation of genetic capability – as a form of renewable resource – is a fundamental method for increasing yields. To do this we must harmonize the biological needs of the given variety, its ecological attributes, with the circumstances of its cultivation.   Today, the soybean is one of the most important plant sources of protein and vegetable fats (Bódis and...

By harvesting fungal spores from partly resistant varieties (as is the practise in normal organic seed production and farming), virulent races of common bunt builds up to devastating levels. The experiment shows that virulence against rare resistance genes to common bunt might be more frequent than expected, since European resistance screening so far have been done without preselecting of virulent races.

Phylogenetic analyses of sequences of the SSU–ITS–LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on...

Neue Strategien zur Regulierung von Schädlingen im Obstbau
Provedor de dados: 21
Im biologischen Obstbau werden möglichst alle indirekten Methoden zur Regulierung von Schädlingen genutzt (Sortenwahl, funktionelle Biodiversität). Dennoch müssen für den Bioobstproduzenten Möglichkeiten der direkten Regulierung der Schädlinge erarbeitet werden, um bei Schädlingskalamitäten eingreifen zu können. Ungelöste Probleme sind z.B. Kirschenfliege, Birnenblattsauger, diverse Wicklerarten und Blutläuse. Sie verursachen grosse Ertrags- und Qualitätseinbussen. In verschiedenen Projekten werden die Möglichkeiten der direkten Regulierung mit insektiziden und anderen pflanzenschützenden Stoffen geprüft.

Copper-based fungicides are used to control the disease in organic vineyards. However, since 2006, copper use has been limited by an European Commission regulation. In this study conducted from 2004 to 2007, we tested materials that might replace copper in organic viticulture, under controlled greenhouse and field conditions at two locations in Europe (northern Italy and Switzerland). We tested 112 different treatments, including biocontrol agents, materials of animal origin, homeopathic preparations, inorganic materials, microbial extracts, natural derivatives, plant extracts, physical methods and synthetic...

Laboratory Studies of the Activity of Spinosad against Leptinotarsa decemlineata (Say) Depending on Different Temperature
Provedor de dados: 21
Autores: Kowalska, Jolanta.
Mortality of the Colorado potato beetle larvae (Say) and adults caused by commercial formulation of spinosad at 15, 20 and 250C was determined under laboratory conditions.  The insects and the leaves of potatoes were sprayed with the insecticide. Thus, the insecticide was toxic by exposure to treated surfaces and ingestion. Three concentrations of insecticide were used: 0.2%, 0.1% and 0.05%. The effect was assessed the 6th day after treatment. All concentrations caused mortality both adults and larvae; however mortality of tested insect stages increased as concentration of spinosad increased. For adults was observed the highest mortality in combination with 0.2% at 150C, whereas at this same temperature in combination with 0.1% was reached the lowest...

Relevance of hot water treatments for decay control
Provedor de dados: 21
Autores: WARLOP, Francois; BOMPEIX, Gilbert.
In France, postharvest decay can lead to important losses in the case of stone fruits, as for pome fruits. Many farm-research trials with natural fungicides (vegetal extracts, mineral compounds) gave no satisfying results yet, and conventional growers also face difficulties to manage diseases with resistance appearance, and inputs reduction strategy to fit consumers expectations. Postharvest treatments seem to have an interest to decrease development of decay (Monilia sp., Rhizopus sp., Penicillium sp.,...) in storage rooms. Hot water treatment offers many advantages (compared to active compounds used after harvest) that will be presented hereafter. Its use in packing houses however remains tough, since cultivar susceptibility to heat injury may vary,...

Autores: Barloggio, Guendalina; Tamm, Lucius; Oberhänsli, Thomas; Nagel, Peter; Luka, Henryk.
This work, which is part of a project called Biocomes (www.biocomes.eu), focuses on the control of the cabbage moth Mamestra brassicae (Linnaeus, 1758) (Lepidoptera: Noctuidae) through mass release of the egg parasitoid Telenomus sp. (Hymenoptera: Scelionidae). In the first year of the project we conducted different experiments to undercover aspects of the biology of this egg parasitoid that could help the creation of an efficient rearing system. Parallel we developed a species specific primer for the molecular species determination. Here we will present the most important results.

Somatic embryogenesis (SE) is the most striking and prominent example of plant plasticity upon severe stress. Inducing immature carrot seeds perform SE as substitute to germination by auxin treatment can be seen as switch between stress levels associated to morphophysiological plasticity. This experimental system is highly powerful to explore stress response factors that mediate the metabolic switch between cell and tissue identities. Developmental plasticity per se is an emerging trait for in vitro systems and crop improvement. It is supposed to underlie multi-stress tolerance. High plasticity can protect plants throughout life cycles against variable abiotic and biotic conditions. We provide proof of concepts for the existing hypothesis that alternative...

An assessment of apple varieties for their suitability in organic production systems
Provedor de dados: 21
Autores: Fitzgerald, J.; Cross, J.; Berrie, A.; Cubison, S.
Twenty seven varieties of apple were assessed for their susceptibility to apple scab,  mildew and rosy apple aphid in a replicated experiment at East Malling Research. The  varieties most affected by mildew were Goldrush, DL11, Liberty, Bohemia and Pinova.  Ceeval, Discovery, Edward VII, Howgate Wonder, Rajka, Rebella and Topaz had the  lowest incidences of mildew. The highest incidence of scab occurred on Pilot and Pinova,  but infestation was low throughout the assessment period. In 2006 when aphid populations  were high, Liberty, Goldrush and Delorina had no aphid infestations, and low infestations  were seen on Edward VII, Resi and Santana.

Practical experience with the use of Baking Powder (potassium bicarbonate) for the control of Apple Scab (Venturia ineaqualis)
Provedor de dados: 21
Autores: Trapman, M.
In small plot trials, performed by several institutes in the past years, potassium bicarbonate  proved to be a promising alternative to the use of copper for the control of apple scab in  organic orchards. Feasibility, effectiveness, consequences, and side effects of the  replacement of copper by bicarbonate under practical conditions are largely unknown. In  2007 Five Dutch organic apple growers compared a bicarbonate based scab management  strategy with their standard spray program. The use of 5 kg potassium bicarbonate + 2 kg.  wettable sulphur shortly before rain or during infection development, was the core of the  strategy. It was concluded that the control of apple scab with the potassium bicarbonate  strategy was as effective as the standard spray...

Saatgut-Testmethoden für Falschen Mehltau an Feldsalat
Provedor de dados: 21
Autores: Schärer, Hansjakob; Penzkofer, Lena; Reents, Hansjürgen; Brändle, Frank.
Peronospora valerianellae is one of the most important pathogens of corn salad. It is  seedborne and besides seed treatments there is no possibility to control the disease.  The wash-off-test and the grow-out-test are currently in use to test seed lots for the  presence of the pathogen. Despite these test methods, there are still seed lots that  show infected plants during production of corn salad. This indicates that a low  infection rate of a seed lot (&lt; 0.25% - 1%) may lead to serious problems in grower’s  production units. To allow an improved identification of seed lots with low infection  rate, a specific PCR-based detection method for P. valerianellae was developed.  Three test methods were compared for their efficacy to detect contaminated seed...

Pesticides are used to protect crops from diseases and pests. Their application in agriculture has been in existence since ancient times to date. They have also been used in growing vegetables especially exotic vegetables that are more prone to pests and diseases. There have been concerns over indiscriminate use of pesticides by farmers to grow vegetables especially for local markets since there are no guidelines on Maximum residue levels. This study was done to determine the concentration of cypermethrin and lambda-cyhalothrin pesticide residues in Collard (Brassica oleracea var. acephala) Tomatoes (Solanum lycopersicum) and swiss chard (Beta vulgaris subsp. cicla). The samples included both organic and conventional vegetables that use chemical...

IPM strategier
Provedor de dados: 21
Autores: Sigsgaard, Lene.
Forebyggelse er fundamentet for integreret plantebeskyttelse (IPM), og med en god præventiv indsats opnås et robust dyrkningssystem. Hvis denne indsats ikke er tilstrækkelig, udvælges først skånsomme metoder som biologisk bekæmpelse og som sidste udvej pesticider. IPM opstod som reaktion på alvorlige pesticidproblemer i 1960erne og frem. IPM er i Europa udviklet og beskrevet af IOBC-WPRS (1). IPM indgår i EUs Direktiv 2009/128/EF om indsatsen for en bæredygtig anvendelse af pesticider (annex 3), og vigtigheden af forebyggelse understreges.

Résumé    La culture de colza bio en Suisse ne permet pas de couvrir la demande du marché. Cela est, en partie, dû au fait que cette culture est chaque année attaquée par les méligèthes du colza qui engendrent d’importants dégâts voir des destructions totales. Les moyens de lutte mis à disposition des agriculteurs en agriculture biologique sont relativement restreints. De plus, aucun d’eux n’a, à l’heure actuelle, démontré une grande efficacité.  Dans le canton de Vaud, M. Roulin produit du colza bio avec un rendement moyen avoisinant les 30 dt/ha. Une étude est donc menée afin de déterminer si la production atteinte par cet exploitant est le résultat de la lutte par dynamisation de méligèthes et des produits Vitalsel.

Control methods against bugs (Hemiptera; Heteroptera) in organic apple and pear production
Provedor de dados: 21
Autores: Jaastad, G.; Trandem, N.; Hovland, B.; Opedal, O.; Mogan, S.; Røen, D.; Sørum, O.; Bjotveit, E.
True bugs (Hemiptera; Heteroptera) are important pests in fruit production in Norway. In organic fruit pro-duction they may damage up to 40% of the crop. Several of the Heteropteran species attacking apple and pear are polyphagous, with many other hostplants than pome fruit. In organic production few control meth-ods are available against bugs. In this study we have tried a cultural control method (mowing of ground-cover) as well as spray applications of various biological insecticides against bugs. Spray application of azadirachtin (NeemAzal), rape oil and garlic extract (Ecoguard) were tested. Results indicate that the effect of mowing groundcover inside the orchard is variable and small. Applying NeemAzal reduced the number of bugs and damage. Oil and...

Entwicklung und Darstellung von Strategieoptionen zur Behandlung von Saatgut im ökologischen Landbau
Provedor de dados: 21
Die Verwendung gesunden Saatguts spielt eine große Rolle im ökologischen Landbau. Zum einen, da schlechte Saatgutqualität einen lückigen Aufgang des Saatguts und somit Ertrags- und Qualitätseinbußen bedeutet und zum anderen, weil in den nächsten Jahren ein möglichst vollständiges Zurückgreifen auf Öko-Saatgut angestrebt wird.

Die befruchteten Weibchen überwintern in Kolonien unter den Knospenschuppen und besiedeln schon im zeitigen Frühjahr die sich entfaltenden Blätter (Jeppson et al. 1975). Durch die Einwanderung der Milben ins Blattmesophyll wird die Bildung von Blattpocken ausgelöst (Baillod &amp; Höhn 1991). Geschützt im Inneren der Pocken findet die Eiablage und Juvenilentwicklung statt. Die jungen Adulten der nächsten Generation verlassen die Pocken, um neue Blätter zu besiedeln. Pro Jahr können 2-4 Generationen beobachtet werden (Alford 1992, Bovey et al. 1979, Friedrich...

Autores: Metral, Raphaël; Rapidel, Bruno; Delière, Laurent; Petitgenet, Morgane; Lafond, David; Chevrier, Christel; Bernard, François-Michel; Serrano, Eric; Thiollet-Scholtus, Marie; Wéry, J.
The results of our re-design and experimentation of grapevine agrosystem, as well as on the other crops (Lançon et al., 2007 and Wery &amp; Langeveld, 2010) show promising perspectives of the prototyping method to achieve high goals for performance and innovation. The complexity of the grapevine agrosystem (ie the number of technical interventions and their potential interactions) requires a strong systemic approach at the interface between the technical and biophysical dimensions of cropping systems (Rapidel et al., 2009). The approach must implement agro-ecological processes to greatly limit inputs. It also required a high innovation and significant changes in the grapevine agrosystem genetics, structure and management. Our results point out the need to...

Fruit thinning in organic apple growing with optimized timing and combination strategies including (new) natural spray products and mechanical rope-devices
Provedor de dados: 21
Autores: Weibel, Franco P.; Chevillat, Véronique S.; Tschabold, Jean-Luc; Stadler, Walter.
The aim of our study was to find new thinning methods for organic apple production able to fulfil the standards of Bio-Suisse, the main label organisation of the organic food sector in Switzerland.   The 14 trials reported were carried out during flowering period in 2003 and 2004 on the cultivars Pinova, Gala, Maigold, Elstar, Golden Delicious and Otava at different sites. The results confirm the good efficiency of mechanical thinning with the rope thinner and the thinning potential of vinasse, a by-product of molasses. Different vinasse products were tested (K-Vinasse, light-vinasse, N-Vinasse) and it was observed that those containing less nitrogen had a minor thinning effect. To avoid phytotoxicity on leaves, the concentration of N-Vinasse should not...

Leaf stripe resistance of spring barley cultivars
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.
Results of six years of screening trials clearly indicate that effective resistance against barley leaf stripe is available, also in modern cultivars. Among the spring barley cultivars that are currently most widely grown in Denmark, Cabaret, Troon, Sebastian, Justina and Brazil appear most resistant, but only Brazil combines a favourable resistance performance (= low mean and standard deviation of environment-adjusted leaf stripe incidence) with a high number of observations (= years of testing). However, the cultivars appearing most resistant over the years are relatively old ones such as Vada, Alabama, Odin and particularly Scarlett, which has been resistant in all years in which it was tested. Amongst the new cultivars, Marigold, Native and SW Immer...

Perspektiven ökologischer Regulierungsverfahren für den Erbsenwickler (Cydia nigricana, Lep. Tortricidae) in Saat- und Gemüseerbsen mit Sexual-Pheromonen und Granuloseviren
Provedor de dados: 21
Autores: Saucke, Helmut; Brede, Uwe; Rama, Franco; Kratt, Armin; Lorenz, Norbert; Zimmermann, Olaf.
Aufgrund der in den letzten Jahren in Deutschland stetigen gestiegenen Anbaufläche für Körnererbsen ist das Schadpotential einiger Leguminosenschädlinge, insbesondere des Erbsenwicklers (Cydia nigricana (Lep.: Tortricidae))deutlich gestiegen. In der ökologischen Vermehrung von Körnererbsensaatgut beeinträchtigt erhöhter Wicklerbefall die Keimfähigkeit, Triebkraft und auch die Saatgutreinheit  durch sich festsetzenden Unkrautsamen in angefressenen Saaterbsen. Dies kann zur Abstufung ganzer Saatgutpartien führen. Weiterhin treten in den letzten Jahren Probleme im Vertragsanbau von Öko-Gemüseerbsen für die Tiefkühlbranche auf. Dort droht bereits mit der Überschreitung von 0,05% C. nigricana-geschädigter Erbsen die Aberkennung und damit Totalausfall für die...

Feldversuche zur Wirkung von Spinosad-, Neem- und B.t.t.-  Präparaten auf die Regulierung des Kartoffelkäfers  (Leptinotarsa decemlineata Say)
Provedor de dados: 21
Autores: Kühne, Dr Stefan; Priegnitz, Uta; Ellmer, Prof. Frank; Moll, Dr. Eckard; Kowalska, Dr. Jolanta.
The Colorado potato beetle (CPB) is one of the most important pests on potatoes  (Solanum tuberosum). In many areas, preventive measures are not sufficient  enoughto prevent the damage caused by the CPB. Therefore insecticides such as  neem and Bacillus thuringiensis v. tenebrionis (B.t.t.) have an important role in organic  potato production in Germany. The new insecticide Spinosad was added to Council  Regulations (EEC) No. 2092/91 on organic production in 2008. It is now possible to  use Spinosad in organic agriculture in the EU. The active ingredient of Spinosad is  obtained from the bacterium Saccharopolyspora spinosa through fermentation. Field  studies compared three treatments to control CPB in 2008. 1: single Spinosad  treatment (24 g/ha active...

Autores: Jong, Ir. P.F. de; Heijne, Dr. Ir. B.
Leaves from organic apple trees were dipped with different organic materials and leaves were placed on the orchard floor in autumn. Leaf area and the amount of ascospores of Venturia inaequalis were measured in spring. The objective of this research was to find alternatives for urea that simulate the decomposition of apple leaves and reduces the asco-spore production. In both years urea gave an increase of the leaf degradation and a significant reduction of the number of ascospores. The antagonist Coniothyrium minitans had no significant effect on the ascospore production in both years but decreased the leaf degradation. Beet pulp showed a significant reduction of the number of spores but reduced the leaf degradation rate. Applying extra earthworms...

Various ways for successful Cultivar introduction in the market
Provedor de dados: 21
Autores: Nuijten, E.; Zeelenberg, Arend; Janmaat, Leen; Lammerts van Bueren, E.T.
Organic production requires novel, robust cultivars especially for crops such as apple, grape, tomato and potato which are very disease susceptible and are often protected by copper compounds. The European project CO-FREE aims to develop innovative methods, tools and concepts for the replacement of copper to reduce the use of copper in organic farming systems. One key strategy is the introduction of resistant cultivars. However, previous studies have shown that the introduction of novel cultivars often meets substantial obstacles as retailers’ and/or consumers’ awareness has to be generated in order to open the market. Resistance is an important issue for farmers but not immediately appealing for consumers as they are hardly aware of the fact that current...

Provedor de dados: 21
Autores: Volakakis, Mr N.; Eyre, Dr M.D.; Kabourakis, Dr E.; Leifert, Prof C.
Olive fly activity and olive fruit infestation was monitored in a table olive orchard in southern Crete throughout most of 2006 using McPhail traps. Flies were trapped weekly for 40 weeks, starting at the beginning of February. The fly data was split into 10 four-week periods. Male, female and total fly activity was significantly related to sampling period, maximum temperature and relative humidity but the pattern of catches was not consistent. Activity increased from February until July but declined in August and was very low in September, October and November. The low activity in the last three months was reflected in low fruit infestation levels, with a maximum of 3.6% in October which contrasts with infestation levels usually around 30%. Olive fly...

Using multi-temporal sensor-based measurements in early growth stages to estimate potential yield of spring barley (Hordeum vulgare L.) varieties in competition with weeds
Provedor de dados: 21
Autores: Hansen, Preben Klarskov.
At the time for weed control, either chemical or physical, the potential yield of the crop (and thus the potential size of the yield loss due to weeds) is very uncertain, as only a minor part of the growing season has passed and the time for the major yield formation is after the weed control.  The aim of this study was to investigate four scenarios of using sensor-based reflectance, vegetation cover- and canopy structure measurements in the early growth stages to estimate the potential yield of four pure spring barley varieties and four variety mixtures of spring barley grown in competition with weeds under two different nutrient levels in two years.

Orchards, as intensive cropping systems, often have low diversity of plant species, which limits the promotion of natural enemies for pest control. The implementation of agri-environmental schemes, such as flower strips, could enhance biological control. We developed perennial, multifunctional flower strips with native plant species. In the second and third year after sowing, plant diversity and ground cover between flower strips (FS) in the drive alleys and the spontaneous orchard vegetation in control plots (Cont) were compared in 19 experimental blocks of eight organic apple orchards in six European countries. On average 73.7% of the sown plant species were established and plant diversity of FS was on average 43% higher than in Cont. Multivariate...

In den Jahren 2004 und 2005 wurde eine neue Formulierung von Kaliumbicarbonat (Armicarb) gegen Schorf und gegen Regenflecken geprüft. Armicarb zeigte ähnlich gute Ergebnisse wie die Referenzverfahren Netzschwefel und Kupfer. Auch gegen die Regenfleckenkrankheiten zeigte Armicarb ausgezeichnete Wirkung. Mögliche Nebenwirkungen wie die Förderung von ‚Lentizellen-Spot’ müssen noch näher überprüft werden. Armicarb wird vom Bundesamt für Gesundheit (BAG) als nicht-toxisch eingestuft und es wurden deshalb auch keine Grenzwerte festgelegt. Armicarb hat sehr interessante Eigenschaften als Pflanzenschutzprodukt und wir erwarten, dass die bio-spezifischen Anforderungen bezüglich Zusammensetzung und Risiko-Profil weitgehend erfüllt werden.

Autores: Sylla, Justine; Alsanius, Beatrix W.; Krüger, Erika; Reineke, Annette; Strohmeier, Stephan; Wohanka, Walter.
The increasing use of biological control agents (BCAs) against Botrytis cinerea in strawberry raises the question of whether there are any undesirable impacts of foliar applications of BCAs on nontarget microorganisms in the phyllosphere. Therefore, our objective was to investigate this issue within a field study. Strawberry plants were repeatedly sprayed with three BCAs—namely, RhizoVital 42 fl. (Bacillus amyloliquefaciens FZB42), Trianum-P (Trichoderma harzianum T22), and Naturalis (Beauveria bassiana ATCC 74040)—to suppress Botrytis cinerea infections. Microbial communities of differentially treated leaves were analyzed using plate counts and pyrosequencing and compared with the microbial community of nontreated leaves. Plate count results indicate that...

Assessment of disease in low-input cereal cropping systems and variety trials
Provedor de dados: 21
Autores: Hovmøller, M.S.; Pinnschmidt, H.; Willas, J.; Østergård, H.
Disease assessment is the basis for describing disease resistance characteristics of commercial varieties in national variety lists for all crops where disease is considered a problem. It is well known that ‘disease’ in a specific situation depends on a whole range of interacting hosts, pathogens and environmental conditions. However, the biological complexity conflicts with the wish to express disease resistance characteristics of a variety as a single score per disease. This problem will be illustrated by basic dynamics of growth and senescence of both host and pathogen over time. Disease expressed in terms of absolute diseased leaf area, disease relative to total leaf area or green leaf area will be discussed in general. Two particular problems in...

Study of trapping systems for control of bactrocera oleae (gmelin)(diptera:tephritidae) in crete olive groves
Provedor de dados: 21
Autores: Alexandrakis, V.; Varikou, K.; Kalaitzaki, A.
Studies have been carried out the last four years to search for improved mass trapping systems for the control of olive fruit fly in olive groves in Chania, Crete (Greece). Trapping materials, which include various food and sex attractants and different types of traps (liquid and paper traps), were tested for their attractiveness and effectiveness in field trials.   Among the tested attractants (Entomella 50 (E50), Entomella 75 (E75), Dacus bait 100 (Db100), Ammonium sulphate (As) and Sex pheromone (Sp)), the hydrolyzed protein ‘Db100’ showed the highest attractiveness regardless of the ‘Sp’. Among the tested traps (Daidalos, Elcofon, Zervas, Agrisense &amp; Ecotrap), Daidalos captured significantly more flies than the other traps.  When the traps were...

Strohmulch und Vorkeimen zur Minderung des Virusrisikos in ökologisch produzierten Pflanzkartoffeln
Provedor de dados: 21
Autores: Döring, Thomas F.; Saucke, Helmut.
Das von Blattläusen übertragene Y-Virus der Kartoffel (PVY) stellt eines der Hauptprobleme bei der vegetativen Pflanzkartoffelvermehrung dar, da bei einem Anteil virusinfizierter Knollen über 8% die amtliche Anerkennung als Pflanzgut ausgeschlossen ist. Diesem Risiko steht bei Anerkennung jedoch ein hoher wirtschaftlicher Erlös gegenüber. Das für ökologische Produzenten ab 2004 geltende Verbot der Verwendung von konventionellem Pflanzgut läßt einen steigenden Bedarf an Ökopflanzgut erwarten. Schon jetzt bestehen jedoch v.a. nach blattlausreichen Jahren Engpässe in der Verfügbarkeit von zertifiziertem ökologisch erzeugten Pflanzmaterial. Ziel war daher die Evaluation und Optimierung verschiedener kulturtechnischer Verfahren zur Minderung des Virusrisikos im...

Development of a dynamic population model as a decision support system for Codling Moth (Cydia pomonella L) management
Provedor de dados: 21
Autores: Trapman, M.; Helsen, H.; Polfliet, M.
In 2004 RIMpro-Cydia was developed as a dynamic population model that simulates the  within-year biology of a local codling moth population. The model is meant to be used by  growers and advisors to optimize the control of codling moth populations in organic and  integrated managed orchards. The model is based on literature data and unpublished  research data. Fractional boxcar trains are used to mimic the dispersion in the  developmental processes. The model is run in real time on the data input of local weather  stations, starting on 1 January. The output of the model was compared with the results of  field observations in three years in an untreated orchard. In the years 2005 to 2007 the  progress in egg deposition as predicted by the model was in...

Wuchsdepressionen von Gehölzarten im Baumschulbereich
Provedor de dados: 21
Autores: Spethmann, Wolfgang; Wilstermann, Maike.
Im Rahmen des Projektes wurden wissenschaftliche und populäre Veröffentlichungen zum Themenbereich Wachstumsdepressionen, Nachbauprobleme, Bodenmüdigkeit und Allelopathie recherchiert und ausgewertet. Es wurden Praktiker, Berater und Wissenschaftler befragt und die jeweiligen Ergebnisse in 3 Workshops diskutiert. Rosaceae sind von den Nachbauproblemen am stärksten betroffen. Die größte wirtschaftliche Bedeutung haben dabei Rose und Apfel. Mit großer Sicherheit kann ein Zusammenhang zwischen einem Befall mit Aktinomyceten und einer Reduktion des vegetativen Wachstums bei Malus festgestellt werden. Obwohl andere Rosaceae davon ebenfalls betroffen sind, konnten als Ursache für die Müdigkeit bei Rosen, bisher keine Aktinomyceten festgestellt werden....

Effect of Strategic Irrigation on infection of Apple scab (Venturia inaequalis)
Provedor de dados: 21
Autores: Korsgaard, Maren.
Strategic irrigation is a method to prevent Apple scab. It is performed by irrigating the orchard floor in dry periods during spring, 24 hours before rain forecast. Irrigating the old leaves on the orchard floor will elicit the release of ascospores, but due to the dry trees and the dry weather, the ascospores dry out without causing infections.

Slaked lime against european fruit tree canker: efficacy and introduction into practice
Provedor de dados: 21
Autores: Heijne, Bart; Jong, Peter Frans de; Wenneker, Marcel; Jansonius, Pieter Jans.
European fruit tree canker, caused by Nectria galligena, is a major disease in organic apple cultivation. No copper can be used in Denmark and the Netherlands to control the disease. Removal of cankers is the only remaining method to control the disease. Slaked lime (calcium hydroxide) was applied at 50 or 100 kg/ha three times during the leaf fall period to protect apple trees against the disease. Experiments under high inoculum pressure showed a reduction in newly formed cankers of 57, 35 and 60 % with respect to untreated for 3 years respectively. The chemical standard thiophanate-methyl further reduced the number of newly formed cankers by 99, 60 and 89 % with respect to untreated for these 3 years respectively in these experiments. These results...

Stable and attractive organic bread based on increased usage of Norwegian grown wheat
Provedor de dados: 21
The project shall lead to increased use of Norwegian wheat in organic bread, and establish a knowledge step-stone needed for contributing to the National goal of 15% organic food consumption. An increasing amount of organic grown wheat is produced in Norway, but it fails to reach the organic market. The bakeries producing organic bread use imported wheat due to unstable quality of the Norwegian wheat. In order to use more Norwegian organic wheat for food there is a need for more stable quality, improved utilisation of quality control, sorting and blending to level out variations, and improved knowledge on how the baking process can be adapted to the flour quality. By creating knowledge on how gluten proteins are built up during the growing season when...

Grünland und Futterbau
Provedor de dados: 21
Autores: Leisen, Edmund.
Einleitung:  Im Ökologischen Landbau bilden Dauergrünland (mehr als 50 % der Öko-Fläche in NRW) und Kleegras die Hauptfuttergrundlage. Zusätzlich werden als Grundfutter je nach Betrieb und Standort Getreide, Getreideleguminosengemenge oder Mais zur Gewinnung von Ganzpflanzensilage angebaut.    Landwirte und Berater können nur bedingt auf die Erfahrungen aus konventionellen Versuchen zurückgreifen. Das gilt zwar auch für andere Bereiche des Ökologischen Landbaus. Beim „Mischanbau unterschiedlicher Arten“ (Grünland, Kleegras, Getreide-Leguminosengemenge) wirkt sich das Anbausystem aber stärker aus als bei Reinkulturen. So führt der Verzicht auf leicht verfügbare Stickstoffdünger beispielsweise zu einer veränderten Pflanzenzusammensetzung. Nicht nur der...

Organic farming has been identified as the road map for food sovereignty, economic security, and alleviation of food toxicity. And, with changing climatic patterns it has become more of a necessity for harnessing both mitigation and adaptation potentials. For sustainable agriculture qualitative developments of soil has been prioritized. But it has been a time taking process, moreover; component wise redressal has not provided much relief considering that still now not even 1% of total agricultural production world over is organic. To reach the objective in a time bound manner, besides healthy soil, healthy plant system has become pre-requisite, as also supported by ‘Trophobiosis theory’ of French scientist F. Chabassou (1985) that depicts ‘Healthy Plants’...

Novel development of heat treatment techniques for seed surface sterilisation
Provedor de dados: 21
Autores: Borgen, Anders; Krebs, Niels; Langkjær, carsten.
Heat treatment to prevent seed borne diseases, e.g. in the form of hot water or warm humid air, will normally heat up the entire seed. Heat treatment of the seed embryo will always have a negative side-effect on seed vigour and the duration of several minutes are difficult to implement in seed plans treating huge volumes of seed. However, in the case of common bunt in wheat and similar diseases, where the inoculum is transmitted as fungal spores on the surface of the seed, an uniform and efficient surface sterilisation will be sufficient to prevent the transmission of the disease.     To test the effect of surface heat sterilisation of seed, an equipment was developed, where seeds were exposed to a combination of steam and ultrasound. The principle is that...

First results with the Gas Discharge Visualisation (GDV) method (Kirlian photography) to assess the inner Quality of apples
Provedor de dados: 21
Autores: Weibel, Franco P.; Saikov, Aleksander; Bigler, Christoph.
GDV technology can provide useful information for distinguishing healthy and stressed plants and, in some cases, it can provide useful information for distinguishing different varieties and rootstocks. It can also provide information for distinguishing fruits grown using different fertilization treatments. However, in our cases with fruit of very similar standard quality, we were not able to find complementary information to distinguish organically from conventionally grown apple fruit. Currently we are carrying out two larger and refined studies on just that topic with 5 conventional/ organic comparison pairs from harvests of two years.

Bio-fortification and isotopic labelling of Se metabolites in onions and carrots following foliar application of Se and 77Se
Provedor de dados: 21
Autores: Kapolna, Emese; Laursen, Kristian Holst; Husted, Søren; Larsen, Erik H.
The aims were to bio-fortify onions by foliar application of selenium (Se) and to intrinsically label bioactive Se-metabolites in onion and carrot by enriched, stable77Se for use in human physiological studies. Onion bulbs and leaves were enriched in Se by repeated foliar spraying of 10 or 100 μg Se mL-1 solutions of sodium selenite (Se(IV)) or sodium selenate (Se(VI)). ICP-MS analysis of onion leaves and bulbs showed that the Se concentration was enhanced by up to a factor of approximately 50 and 200 in bulbs and leaves, respectively. HPLC-ICP-MS analysis of proteolytic plant extracts showed that foliar application of Se(IV) gave rise to bio-synthesis of a higher fraction of the desired organic Se species and was better tolerated by the plants than...

Non- chemical methods of seed treatment for control of seed- borne pathogens on vegetables
Provedor de dados: 21
Autores: Amein, T.; Wright, S.A.I.; Wikström, M.; Schmitt, A.; Koch, E.; van der Wolf, J.; Groot, S.; Forsberg, G.; Werner, S.; Jahn, M.
Abstract – The aim of EU-project "Seed Treatments for Organic Vegetable Production"  (STOVE) was to evaluate non-chemical methods for control of seed-borne pathogens in organic vegetable production. Physical (hot air, hot water and electron) and biologi-cal (microorganisms and different agents of natural origin) methods have been investigated. Trials have been carried out with different patho-systems such as cabbage / Alternaria spp and parsley / Septoria pet-roselini. Good control was generally obtained with the physical methods. In field trials, the yield of parsley naturally infested by S. petroselini was increased by 20 % when the seeds were treated with hot air. In trials performed under controlled conditions, also thyme oil treatment increased the...

Kväveformens inverkan på produktkvalitet: Innehåll av vitamin C och antioxidanter i tomat
Provedor de dados: 21
Bakgrund &amp; syfte:  Mot bakgrund av regeringens mål att 20 % av åkermarken ska brukas ekologiskt år 2005 ökar vikten av att få kunskap om hur olika odlingssystem påverkar kvalitén på våra livsmedel. Ekologisk odling spelar en viktig roll i utvecklingen av uthålliga system som producerar livsmedel av hög kvalitet. Det finns dock flera målkonflikter, såsom att nå stor avkastning utan användning av kemiska gödselmedel eller pesticider, och minimering av växtnäringsförluster. Projektets syfte var att testa om kvävemängd och kväveform som skiljer sig mellan organiska och mineralgödselmedel påverkar tillväxt, skördemängd och produktkvalitet (smak och näringsinnehåll) i en tomatodling på olika sätt, och om en näringsbegränsning korrelerar med liten avkastning...

The challenges and potential benefits of perennial organic cropping systems-example of organic top fruit
Provedor de dados: 21
Autores: Firth, C; Cubison, S; Cross, J.
Of all the organic food sectors in the UK, top fruit production is one of the least developed. Despite strong consumer demand and high prices for organic fruit, UK production remains small and 90% of supplies are imported. Current methods of production are unsatisfactory with low yields and erratic quality, with resulting variable economic performance. Pest and disease problems are one of the main reasons for this poor performance, with current varieties being unable to provide sufficient resistance. New varieties and an improved pest and disease management programme, identified as part of a HORTLINK project, offer new hope to the sector. There are now opportunities for the sector to grow and provide greater UK supplies of top fruit, in addition to...

Un nouveau ravageur menaçant pour les cultures fruitières biologiques : Drosophila suzukii
Provedor de dados: 21
Autores: WARLOP, FRANCOIS; MANDRIN, Jean-François; Weydert, Claire; Filleron, Emmanuelle; Turquet, Marion; Gallia, Valérie.
A new pest has been officially described in France in 2010. Drosophila suzukii (also called Spotted-wing Drosophila) attacks many species of fruits, before ripening, and economic consequences are very important. Because of a very high fecundity and a great lack of knowledge on this invasive pest, there is a high need of applied research to provide efficient techniques to conventional and also organic farmers. Indeed, organic cherry or strawberry production is directly threatened by this new pest. The poster presents different control strategies and state of art for each of them.

Tiltak mot skadegjørere i økologisk produksjon av kålvekster
Provedor de dados: 21
Autores: Serikstad, Grete Lene; Bysveen, Kari; Holz, Thomas.
Mange skadegjørere kan ødelegge kvalitet og avling av kålvekster. Skadeomfanget av de ulike skadegjørerne varierer mellom de ulike kålvekstene, ut fra hva som er matnyttig del av planten og lengden på vekstperioden. Økologisk dyrking av slike vekster krever god kunnskap om  skadegjørerne. Et gjennomtenkt vekstskifte, tilstrekkelig næring og god jordkultur er nødvendig for god vekst og sterke planter. Direkte tiltak må settes i verk til rett tid. Nytteorganismer kan bidra til å redusere skadeomfanget.

Plant protection in organic apple production: A summary of research conducted under the German Federal Programme for Organic Agriculture and other forms of Sustainable Agriculture
Provedor de dados: 21
Autores: ANON, AN.
In this focus area, research projects were carried out on two main subjects: apple scab (Venturia inaequalis) and codling moth (Cydia pomonella). Scab control projects started in 2002, projects on codling moth control in 2006, and research on both topics has intensified since 2010. From the be-ginning, the search for alternative materials for scab control was prioritised, since the use of copper as a treatment for scab is going to be restricted in the future, and the efficiency of materials approved for treating organic apples has often been too low in the past to prevent significant yield losses. Alternative materials were tested and compared, including materials from Inula viscosa, Quillaja saponaria bark, citrus species and Saponaria officinalis. These...

Mildiou de la laitue sous abri : comment faire face ?
Provedor de dados: 21
Autores: Lambion, Jérôme; Mazollier, Catherine.
Le mildiou de la laitue provoqué par Bremia lactucae est une des maladies les plus graves touchant la salade. En Provence où cette culture occupe la grande majorité des tunnels en hiver, les dégâts très importants, parfois dès la pépinière, peuvent entraîner de fortes pertes financières. Cette situation est due à deux facteurs principaux : d’une part au contournement récurrent des résistances génétiques par de nouvelles souches de Bremia (25 races déterminées à ce jour), et d’autre part à la faiblesse des méthodes de lutte biologique possibles contre ce champignon. Cet article paru dans Alter Agri (Editions ITAB) présente les dégâts causés par le mildiou, quelques éléments de biologie de Bremia lactucae, et fait le point sur les méthodes de lutte...

Lutte contre oïdium sur Cucurbitacées - compte-rendu d'essai 2010
Provedor de dados: 21
Autores: Lambion, Jérôme.
En culture maraîchère, l’oïdium constitue une maladie fréquente et parfois grave, notamment sur solanacées et cucurbitacées. Le recours aux variétés tolérantes existe pour certaines cucurbitacées : concombre, melon, courgette mais la sélection se heurte à l’apparition de nouvelles souches qui contournent ces tolérances et les rendent partiellement inefficaces. La lutte directe, préventive ou curative est donc essentielle. En maraîchage biologique, seul le soufre est à la fois autorisé au cahier des charges européen et homologué en France sur certaines cultures : tomate, courgette, concombre, melon. L'objectif de cet essai est de tester des porduits alternatifs au soufre, toxique contre les auxiliaires. Dans les conditions de faible pression en oïdium de...

Autores: FARES, Roula.
The adaptation of potato (Solanum tuberosum) under organic farming is an object of several important researches worldwide. To evaluate potato adaptation under organic farming in Lebanon, the performances of the mostly used three varieties, Remarka, Spunta and Folva, were compared in correlation to 2 fertilizers, an on-farm compost and commercial one (Siforga). A  fertilized control was also used. A Split Plot Design with three replicates was applied. The measured parameters were germination rate, resistance to pathogens, yield, quality control and panel test. Remarka gave the best performances under both the commercial and the on-farm compost: high germination (100%), high resistance to the bacteria Erwinia carotovora and to the fungus Rhizoctonia sp.,...

Soil borne diseases are highly important in organic grain legumes. Suppressive composts are an important measure to control soil borne pathogens in different crops. So far, reports on the foot rot causing pathogens in peas such as Fusarium spp., Phoma medicaginis, Mycospherella pinodes are rare. In our study Phoma medicaginis, Pythium ultimum and Fusarium avenaceum were significantly controlled with yard waste composts demonstrating the principal potential of composts to suppress these diseases. However, the main challenge for organic farmers are to transfer these results to the practise in organic farms. In a field trial with peas 5 and 18 t/ha of compost were applied as broadcast or as strip application while sowing peas with a new developed sowing...

Autores: Wyss, Eric; Tamm, Lucius; Siebenwirth, Joachim; Baumgartner, Stephan.
A laboratory model system with the rosy apple aphid (Dysaphis plantaginea Pass.) on apple seedlings was developed to study the effects of homeopathic preparations on this apple pest. The assessment included the substance Lycopodium clavatum and a nosode of the rosy apple aphid. Each preparation was applied on the substrate surface as aqueous solution of granules (6c, 15c, or 30c). Controls were aqueous solutions of placebo granules or pure water. In eight independent, randomized, and blinded experiments under standardized conditions in growth chambers, the development of aphids on treated and untreated apple seedlings was observed over 17 days, each. Six experiments were determined to assess the effects of a strict therapeutic treatment; two experiments...

The virulence of Finnish Pyrenophora teres f. teres isolates and its implications for resistance breeding
Provedor de dados: 21
Autores: Jalli, Marja.
In Finland, barley, Hordeum vulgare L., covers 50 % of the total acreage devoted to cereal cultivation. The most common disease of barley in Finland is net blotch, a foliar disease caused by the ascomycete Pyrenophora teres Drechsler. Disease resistance based on plant genes is an environmentally friendly and economical way to manage plant diseases caused by biotic stresses. Development of a disease resistance breeding programme is dependent on knowledge of the pathogen. In addition to information on the epidemiology and virulence of a pathogen, knowledge on how the pathogen evolves and the nature of the risks that might arise in the future are essential issues that need to be taken into account to achieve the final breeding aims.    The main objectives of...

Autores: Arnault, Ingrid; Lombarkia, Nadia; Ondet, Sophie-Joy; ROMET, L.; Brahim, Imene; Meradi, Rahma; Auger, J; Derridj, Sylvie.
Abstract  BACKGROUND    The effects of foliar applications of microdoses of sucrose to reduce the damage by the codling moth have been reported from nine trials carried in France and Algeria from 2009 to 2014. The activity of sucrose alone was assessed by comparison with an untreated control and some treatments with the Cydia pomonella granulovirus or a chemical insecticide. The addition of sucrose to these different treatments was also investigated.  RESULTS    The application of sucrose at 0.01% reduced the means of infested fruits with a value of Abbott's efficacy of 41.0 ± 10.0%. This involved the induction of resistance by antixenosis to insect egg laying. Indeed, it seems that acceptance of egg laying on leaves treated with sucrose was reduced. The...

Gulrot konkurrerer dårlig mot ugras første halvdel av sesongen og god avling og kvalitet krever  at dyrkeren er på rett sted til rett tid med ulike tiltak. Forebyggende tiltak som vekstskifte og  god jordkultur er viktig for at gulrota skal komme i god vekst, noe som er et godt planteverntiltak  i seg sjøl. I tillegg er det helt nødvendig med kunnskap om de viktigste skadegjørerne og hvilke  direkte tiltak som kan benyttes.

Mykotoksiner er giftige metabolismeprodukter produceret af svampe. Ordet er afledt af det græske mykês, der betyder svamp. Hvilke mekanismer, der regulerer svampemetabolismen og dannelsen af toksiner, og hvilken rolle metabolitterne har i svampenes livscyklus, ved vi stadig meget lidt om.   Nogle af metabolismeprodukterne er til gavn for mennesker bl.a. ved anvendelse inden for den farmaceutiske industri, andre er skadelige. Ochratoksin A (OTA) er et eksempel på et af de skadelige metabolismeprodukter. Det er et af de vigtigste mykotoksiner globalt set, og sundhedsrisikoen for mennesker og dyr er blevet påvist. OTA er både nephrotoksisk, carcinogent, teratogent og immunotoksisk. I de tempererede områder forekommer OTA specielt i cerealier, hvor det...

In the control of codling moth it is common to combine the granulovirus with other agents,  especially fungicides, in spray application. Therefore the knowledge about the influence of  these agents on the efficacy of the virus in tank mix is very important. Studies on this  subject were part of a project supported by BMELV (German Federal Ministry for Food,  Agriculture and Consumer protection) at the Institute for Biological Control of JKI in  Darmstadt.  The granulovirus of Cydia pomonella (L.) (CpGV) was mixed with 10 different agents at  concentrations as applied in the field. After the exposure the virus activity was calculated  from larval mortality determined in bioassays with neonates of a susceptible codling moth  strain.  Only two agents with a...

This deliverable presents the results of the survey carried out in the frame of Tasks 3.1. and Task 5.1 in the Horizon 2020 Project Organic PLUS. A common table/questionnaire for both tasks was used in order to map the use of contentious inputs linked to plant protection (mainly Cu, S and mineral oils), and the use of peat, plastic and fertilisers used in growing, in 10 countries participating in Organic-PLUS (Denmark, France, Germany, Greece, Italy, Norway, Poland, Spain, Turkey and UK). The survey was carried out mainly by interviewing one to three experienced advisors per crop, asking them to fill in a table describing a typical organic production of the relevant crop, emphasising the use of various inputs. In some cases the survey was based on already...

Culturable Fungi of Stored ‘Golden Delicious’ Apple Fruits:  A One-Season Comparison Study of Organic and Integrated  Production Systems in Switzerland
Provedor de dados: 21
Autores: Granado, José; Thürig, Barbara; Kieffer, Edith; Petrini, Liliane; Fliessbach, Andreas; Tamm, Lucius; Weibel, Franco; Wyss, Gabriela S.
The effects of organic and integrated production systems on the culturable fungal microflora of stored apple fruits from five matched pairs of certified organic and integrated ‘Golden Delicious’ farms were studied at five representative production sites in Switzerland. Isolated fungi were identified morphologically. Colonization frequency (percentage of apples colonized), abundance (colony numbers), and diversity (taxon richness) were assessed for each orchard. The standard quality of the stored fruits was comparable for both organic and integrated apples and complied with national food hygiene standards. Yeasts (six taxa) and the yeast-like fungus Aureobasidium pullulans were the dominant epiphytes, filamentous fungi (21 taxa) the dominant endophytes. The...

Entwicklung eines Zuchtgarten-Befallsmanagements für die Züchtung flugbrandresistenter Sommergersten unter natürlichen Befallsbedingungen
Provedor de dados: 21
Für den ökologischen Landbau sind derzeit keine praktikablen Saatgutbehandlungsmethoden zur Reduzierung des Flugbrandbefalls unter die für die Basis- oder Z-Saatguterzeugung vorgesehene Schwelle in Sicht. Resistenzzüchtung ist momentan die einzige Möglichkeit. Jedoch schrecken viele Züchter bezüglich der Züchtung auf Flugbrandresistenz zurück, aus Angst vor einer unkontrollierten Ausbreitung der Krankheit im Zuchtgarten. Da es im Zuchtgarten auf einzelne Ährennachkommenschaften ankommt, kann ein zu hohes Befallsniveau zum Verlust ganzer Zuchtlinien führen, auch wenn diese aufgrund anderer Eigenschaften für die weitere Züchtung besonders erhaltenswert wären. Ein zu niedriges Befallsniveau erfordert umfangreiche und aufwendige Nachprüfungen mittels...

Mixed cropping systems for biological control of weeds and pests in organic oilseed crops
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Schochow, Martin; Ulber, B; Kühne, Stefan; Rahmann, Gerold.
Agricultural advantages of mixed cropping are gained by biological effects like light competition, offering weed-suppressing capacities or by diversification of plant covers to break development cycles of pests. In a two-year project on mixed cropping with organic oilseed crops these effects were measured. It was found that weeds can be efficiently suppressed in organic linseed (Linum usitatissivum) in crop combinations with wheat (Triticum aestivum) or false flax (Camelina sativa). But linseed development was strictly limited. Also in organic pea production (Pisum sativum) the introduction of mixtures with the oil crop false flax led to a significant decrease of weed population. Either culture showed a balanced plant development. In winter rape (Brassica...

Autores: Schmehe, Ben; Becher, Thorben; Spieß, Hartmut.
In 2005 an organic oat (Avena sativa L.) breeding programme was initiated by the on farm breeding and research institute at Dottenfelderhof, Hessen, Germany, with the purpose of releasing oat varieties suitable for organic agriculture. From the very beginning it was one goal to develop varieties resistant to loose smut of oat (Ustilago avenae), which can be a severe problem for the certification of seeds. Therefore registered varieties as well as gene bank accessions were used for crosses and evaluated for resistance to loose smut over the years. In this paper the selection process is being described and the resistant level of the present filial generations in 2012 is shown. Additionally the results of the evaluation of registered varieties from 2010-12...

Control of apple scab by curative applications of biocontrol agents
Provedor de dados: 21
Autores: Kunz, S.; Mögel, G.; Hinze, M.; Volk, F.
In organic apple growing protective applications with copper, sulphur or lime sulphur are  used for apple scab control. Protective applications have to be repeated when new leaves  unfold. The timing of protective sprays depends on the weather forecast. If forecasted  infection conditions fail to appear, treatments were for nothing. With curative control  agents available, the number of treatments could be reduced. In greenhouse trials we  tested control agents for their protective and curative efficiency against apple scab after  artificial inoculation of potted apple trees. Applications were done 2 hours before  inoculation, 5 hours after inoculation on wet leaves, 5 hours after inoculation during  simulated rainfall or 24 hours after inoculation on wet...

Main source of stem blight infections and possibilities of reducing symptoms
Provedor de dados: 21
Autores: Zellner, Michael; Hofbauer, Johann; Keil, Sven; Benker, Marianne.
Symptomless seed tubers are no guarantee for them being free of tuber blight, therefore they bear the risk of bringing P. infestans to the fields. Because of the high risk of using infected seed tubers control measures are highly recommended. Systemic fungicides spread into the plant tissue and can reduce the growth of the fungus from within the plant. Treating seed tubers with copper is another possibility especially in organic farming. Further research should deal with possibilities to reduce latent infections of seed tubers with P. infestans as they are the main reason for an early outbreak and a strong late blight epidemic.

Tolerance of four spring barley (Hordeum vulgare L.) varieties to weed harrowing
Provedor de dados: 21
Autores: Hansen, Preben Klarskov; Rasmussen, Ilse A.; Holst, Niels; Andreasen, Christian.
We investigated the tolerance to weed harrowing of four spring barley varieties and examined the possible interactions between varietal weed suppressive ability and two nutrient levels. Tolerance was defined as the combined effect of crop resistance (ability to resist soil covering) and crop recovery (the ability to recover in terms of yield). The weed harrowing strategy was a combination of one pre- and one post-emergence weed harrowing. In terms of yield, the four varieties responded significantly differently to weed harrowing and the response depended on nutrient level. At the lower nutrient level, weed harrowing caused an increase in yield of 4.4 hkg ha-1 for a strong competitor (cv. Otira), while there was no effect on yield at the higher nutrient...

Intercropping – The practical application of diversity, competition, and facilitation in arable and organic cropping systems
Provedor de dados: 21
Autores: Jensen, Erik Steen; Hauggaard-Nielsen, Henrik; Kinane, Julia; Andersen, Mette Klindt; Jørnsgaard, Bjarne.
Intercropping (IC) is the simultaneous cultivation of more than one crop species on the same piece of land. The IC practice offers many advantages to organic agriculture in terms of resource use, yield stability, weed management and increased diversification of agroecosystems. Field experiments carried out at two sites in Denmark over three consequetive cropping seasons showed that ICs of cereals and grain legumes gave higher yields, less weeds, lower infection with plant diseases and higher grain quality compared to corresponding sole crops.

Autores: Speiser, Bernhard.
The use of nanoparticles (particles smaller than 100 nanometers) is only at its beginning, but it is already evident that nanomaterials will soon infiltrate most areas of modern life, including many applications in agriculture, food processing, and packaging. Nanoparticles are very heterogeneous with respect to their origin.  With few exceptions, there are no organic production standards relating specifically to the use of nanoparticles. The Soil Association excludes all uses of nanoparticles, and Austria Bio Garantie excludes nanoparticles from organic cosmetics. In a discussion at BioFach 2008, most participants felt that more information is needed in order to make a decision.  Nanotechnology is an up-and-coming technology with a wide array of potential...

Provedor de dados: 21
Autores: Toivanen, Marko; Huttunen, Sanna; Riihinen, Kaisu; Obey, Jackie; Tikkanen-Kaukanen, Carina.
Antimicrobial resistance (AMR) resistance, similar to climate change, is a shared global problem. AMR threatens the effective prevention and treatment of an ever-increasing range of infections. There are plenty of resistant bacteria that cause common infections such as urinary tract infections and pneumonia. In addition to causing death, disability and suffering AMR has huge economic impacts. The alarming increase in drug-resistant bacteria means that there is a need for novel means of fighting against bacterial infections. One feasible approach is to use agents that interfere with the ability of the bacteria to adhere to the tissues of the host, the initial stages of the infectious process. Our research project deals with milk oligosaccharides, wild berry...

Carie du blé : agir avant qu'il ne soit trop tard
Provedor de dados: 21
Autores: FONTAINE, Laurence.
La carie commune du blé (Tilletia caries ou Tilletia foetida)était une maladie courante jusqu’aux années cinquante. La pratique de désinfection des semences par lutte chimique l’a réduite à un état de bruit de fond. Aujourd’hui la maladie est en nette recrudescence, particulièrement en agriculture biologique, sans doute en lien, d’une part, avec l’obligation d’utilisation de semences biologiques donc non traitées chimiquement et, d’autre part, avec le fait que les agriculteurs ne connaissent plus cette maladie et ne prennent pas à temps les précautions qui s’imposent. Le pouvoir de propagation de la maladie est extrêmement important, ce qui en fait un risque majeur en agriculture biologique. Le blé tendre est concerné, mais également ses apparentés, à des...

Gibt es Alternativen zur Anwendung von Kupfer als Pflanzenschutzmittel?
Provedor de dados: 21
Autores: Schleuß, Uwe.
In diesem Artikel geht es um die Umweltauswirkungen von Kupfer, die für den Ökolandbau zugelassenen Pflanzenschutzmittel und die Anwendungsgebiete von Kupfer.    Zusammenfassend wird festgehalten, dass momentan auf den Einsatz von Kupfer als Pflanzenschutzmittel im ökologischen Landbau  noch nicht verzichtet werden kann. Um die Umweltauswirkungen auf Boden und Gewässer so gering wie möglich zu halten, muss die Aufwandmenge deutlich reduziert werden. Dabei muss natürlich die fungizide Wirkung erhalten bleiben. Ein Durchbruch beim Ersatz von Kupferpräparaten ist hinsichtlich Wirksamkeit und Kontinuität noch nicht gegeben. Deshalb ist zunehmend mehr Wert auf Präventionsmaßnahmen zu legen.

Autores: Seljåsen, Randi; Kristensen, Hanne L.; Lauridsen, Charlotte; Wyss, Gabriela S.; Kretzschmar, Ursula; Birlouez-Aragone, Inès; Kahl, Johannes.
The aim of this review is to provide an update on factors contributing to quality of carrots, with special focus on the role of pre- and postharvest factors and processing. The genetic factor shows the highest impact on quality variables in carrots, causing a 7–11-fold difference between varieties in content of terpenes, β-carotene, magnesium, iron and phenolics as well as a 1–4-fold difference in falcarindiol, bitter taste and sweet taste. Climate-related factors may cause a difference of up to 20-fold for terpenes, 82% for total sugars and 30–40% for β-carotene, sweet taste and bitter taste. Organic farming in comparison with conventional farming has shown 70% higher levels for magnesium and 10% for iron. Low nitrogen fertilisation level may cause up to...

Cet article reprend des éléments des journées techniques fruits, légumes et viticulture bio de l'ITAB/GRAB et Bio de Provence (2012). Des expérimentations ont été menées en vergers d'abricotiers pour trouver comment limiter le développement du Monilia Laxa dans les fleurs d'abricotiers en bio. Il apparaît que le cuivre seul est insuffisant, et que la stratégie cuivre+soufre soit plus appropriée. Bakour, Goldrich, TomCot® et Malice® sont des variétés résistantes. Les travaux montrent qu'il existe deux mécanismes de résistance : l'un au moment de la floraison et l'autre au niveau du rameau.

Målet med detta projekt är att studera hur olika gröngödslingsgrödor kan användas i praktisk odling för att förhindra eller reducera angrepp av jordburna skadesvampar på sockerbetor. Ett flertal oljeväxter bl a oljerättika och vitsenap har visat sig ha bekämpande effekt på bl a Aphanomyces cochlioides som är den vanligaste jordburna patogenen på sockerbetor i Sverige. Oljeväxterna innehåller glukosinolater som vid nedbrytning av växtdelarna bildar svavelhaltiga föreningar sk isothiocyanater. Dessa svavelhaltiga föreningar har i laboratorieförsök visat sig kunna hämma flera stadier i svampens utveckling. Även havre innehåller ämnen sk sapponiner som är skadliga för många jordburna svampar.

Effects of landscape context on herbivory and parasitism at different spatial scales
Provedor de dados: 21
Autores: Thies, Carsten; Steffen-Dewenter, Ingolf; Tscharntke, Teja.
Local community structure and interactions have been shown to depend partly on landscape context. In this paper we tested the hypothesis that the spatial scale experienced by an organism depends on its trophic level. We analyzed plant-herbivore and herbivore-parasitoid interactions in 15 agricultural landscapes differing in structural complexity using the rape pollen beetle (Meligethes aeneus), an important pest on oilseed rape (Brassica napus), and its parasitoids. In the very center of each landscape a patch of potted rape plants was placed in a grassy field margin strip for standardized measurement. Percent non-crop area of landscapes was negatively related to plant damage caused by herbivory and positively to the herbivores’ larval mortality resulting...

At present, around 95% of organic production is based on crop varieties that were bred for the conventional high-input sector, lacking important traits required under organic and low-input production conditions. Populations with a high level of genetic diversity are promising for OA (organic agriculture) conditions due to their adaptation, resilience and performance stability in different environments. Organic farming will benefit from cultivars (populations, varieties) that can cope with multiple stresses such as weeds, diseases, pests, climate change and low nitrogen input from manure. In the COBRA project (Coordinating Organic Plant Breeding Activities for diversity), plant genetic diversity and its potential have been investigated from both an...

In the organic apple orchards in South Tyrol different voles (Fam. Arvicolidae) are the cause of big damages on the trees. At present there isn't any product listed t the annex 2b of the EC- decree 2092/91 for organic agriculture, which could control the voles efficiently. Therefore it is quite difficult to control the voles in organic orchards. It is necessary to convince European and national authorities, associations and organs of control to allow the use of suitable products.  Our trials showed that Silmurin, an extract of the red sea-onion (Uriginea marsitima) controls quite efficiently the field mouse (Microtus arvalis), but hasn't any effect against the earth vole (Arvicola terrestris). Against these voles we obtained good results with...

Vigorous seedlings are an important base for vegetable production. Beside the availability of appropriate amounts of nutrients, the health of seedlings is decisive. Soil-borne diseases are a challenging problem in organic seedling production. Here, we present results on the development of disease-suppressive growing media. Three aspects were examined: (i) use of different components of growing media (peat, coconut fiber, wood fiber, compost), (ii) influence of selected organic nitrogen fertilizers and (iii) use of different microorganisms (including commercial biocontrol agents (BCA)). Three plant-pathogen systems were used in this study: cucumber-Pythium ultimum, cress-Pythium ultimum and basil-Rhizoctonia solani. Green waste compost showed a good...

Organic farming is reliant on alternative active substances like plant extracts for plant protection. Limited stability of plant extracts complicates their use and storage.  Consequently, there is a need for the development of novel formulations like encapsulation that stabilize the active substances, control their release and provide an  appropriate handling. In the project DevelOPAR (Development of a plant avian repellent) we illustrate how a repellent plant extract is formulated in order to be applied  as seed-coating protecting seeds not to be eaten by birds. Testing the methods of ionic gelation and complex coacervation we managed to encapsulate the plant extract  and produce homogenous particles that can be applied on corn seeds using a spin coating...

Landscape Structure and Biological Control in Agroecosystems
Provedor de dados: 21
Autores: Thies, Carsten; Tscharntke, Teja.
Biological pest control has primarily relied on local improvements in populations of natural enemies, but landscape structure may also be important. This is shown here with experiments at different spatial scales using the rape pollen beetle (Meligethes aeneus), an important pest on oilseed rape (Brassica napus).  The presence of old field margin strips along rape fields was associated with increased mortality of pollen beetles resulting from parasitism and adjacent, large, old fallow habitats had an even greater effect. In structurally complex landscapes, parasitism was higher and crop damage was lower than in simple landscapes with a high percentage of agricultural use.

Braeburn is quite susceptible to scab and mildew. To regulate this latter disease the organic orchardists use mainly sulphur products. Braeburn however is sensitive to sulphur treatments. Mainly during summer at high tem-peratures the leaves of Braeburn treated with sulphur develop a yellowish colour and necrotic spots. A field-trial was carried out for 2 years to investigate which sulphur formulations and application techniques give less phytotoxic problems to leaves and fruits of the apple variety Braeburn. The results show only small dif-ferences between the...

Effect of cultural methods on leaf spot (Mycosphaerella fragariae Tul.) incidence in strawberries
Provedor de dados: 21
Autores: Schmid, Andi; Daniel, Claudia; Weibel, Franco.
Introduction:  Leaf spot caused by Mycosphaerella fragariae Tul. is one of the most common diseases of strawberry. The control of leaf spot mostly relies on the application of protective fungicides (MAAS 1998). In organic agriculture the use of copper products is effective (VUKOVITS 1980) but this has a negative influence on soil fertility.(BERGMANN 1993).Therefore its use in strawberry crops should also be reduced.

Mit repellenten Duftstoffen gegen den Rapsglanzkäfer (Labortests) (Video)
Provedor de dados: 21
Autores: Alföldi, Thomas; Daniel, Claudia.
Der Rapsglanzkäfer ist ein kleiner Schädling, der zum grossen Ärgernis werden kann. Wenn er im Frühjahr in die Kulturen einfällt, zerbeisst er die Blütenknospen und kann schnell grossen Schaden anrichten. Die Käfer orientieren sich beim Einflug in die Felder am typischen Rapsgeruch. Fremde Gerüche haben dabei eine abschreckende Wirkung auf die Käfer. Kann man diese Gerüche eventuell nutzen, um die Käfer wirksam aus den Feldern zu vertreiben? Und wie findet man den abschreckendsten Geruch?   Dank finanzieller Unterstützung der Migros konnten Laborversuche in einem Olfaktometer durchgeführt werden, die genau diese Fragen beantwortet sollten. Im Video erklärt Claudia Daniel vom FiBL, wie ein Olfaktometer funktioniert.

Autores: Hassall, A.G.; Kristiansen, P.; Taji, A.
This paper reports the findings of two components of a research investigating the viability of organic wine grape production. Firstly the results of a survey of Australian organic wine grape growers’ management practices and secondly the first year findings of an experimental organic vineyard compared to an associated conventional vineyard. The survey found a heavy reliance on sulphur and copper sprays for powdery and downy mildew control. The experimental vineyard showed similar yields to conventional growing and in many cases higher sugar, though some increase in botrytis in organic Shiraz.

Late blight on potatoes in organic farming - prognosis (Öko-SIMPHYT)
Provedor de dados: 21
Autores: Tschöpe, Beate; Kleinhenz, Benno; Keil, Sven; Zellner, Michael.
In organic potato cultivation, late blight (Phytophthora infestans) can cause significant losses. Often, the use of copper is necessary, which is limited in organic farming. Öko-SIMPHYT is a decision support system for the termination of copper spraying and the quantity of copper needed.   First, you have to provide your exact location, the potato variety, the planting density, the condition of the plants and the recent amount of precipitation. Based on that, the tool presents appropriate recommendations.   First, you get a recommended start of treatment. Second, the tool gives a recommendation for the treatment interval, the quantity needed and a possible treatment break as well as a prediction for the risk of infection.

Provedor de dados: 21
Autores: Wibe, Atle; Apenite, Ilze; Baroffio, Catherine; Borg-Karlson, Anna-Karin; Cross, Jerry; Hall, David; Sigsgaard, Lene; Trandem, Nina.
The strawberry blossom weevil (Anthonomus rubi) and the European tarnished plant bug (Lygus rugulipennis)  cause large (10 - &gt;80%) losses in yield and quality in organically grown berries. A consortium with 6 European  countries has been created to work on the management of those pests. The pheromones of A. rubi and L.  rugulipennis have been characterized in England by NRI/EMR. For the attraction of A. rubi the importance of host  plant volatiles in combination with the pheromones has also been documented. The natural semiochemical  mechanisms of sexual attraction and host plant finding of A. rubi and L. rugulipennis will be further studied and  exploited to develop effective semiochemical traps for their management through mass trapping.

Autores: Daniel, Claudia; Matray, Silvia; Stoeckli, Sibylle; Niggli, Urs.
Holistic approaches to pest management that aim at maximising self-regulation and resilience of orchards are a key goal in organic farming (see chapter 2). Pest management starts even before planting an orchard by site selection, orchard layout, planting systems (tree densities and pruning system), choice of cultivar and rootstock as well as cultivation techniques. Cultivation techniques and measures applied for disease control can also influence the dynamics of pest insects within orchards and need to be included in a holistic system view. In addition, the use of flowering strips to enhance natural enemies is a field of intense research. Direct control methods using biocontrol organisms or bio-insecticides are available for many pest insects. However,...

Soil porosity as a habitat for microorganisms
Provedor de dados: 21
Autores: Schjønning, P.; Thomsen, I.K.; Christensen, B.T.
The soil pore system has to be characterized quantitatively in order to describe the soil as a habitat for microorganisms. Soil pore morphology as determined by soil structure may be as important as the size distribution for the transport of gases and nutrients. This study adresses the physical properties of differently textured soils in undisturbed and remoulded state and their effect on microbial activity.  Bulk soil was retrieved from 0-20 cm depth at six locations along a textural gradient in an arable field in Denmark. The samples ranged in clay content from 11 to 45%. The soils were crushed in air dry state, mixed, re-moistened, and exposed to a 9 month period of structure regeneration. Following application of 14C-labelled organic residues, the...

Kaolin, lime and rock dusts to control Drosophila suzukii
Provedor de dados: 21
Autores: Strack, Timo; Cahenzli, Fabian; Daniel, Claudia.
The spotted wing drosophila, Drosophila suzukii, is an invasive pest in Europe and North America, infesting various soft-skinned fruits. Because D. suzukii attacks ripening fruits shortly before harvest, only insecticides with short pre-harvest intervals can be applied. Alternatively, kaolin, lime and rock dusts are non-toxic to non-target organisms, but the whitish coating on fruits potentially deters oviposition of D. suzukii. Therefore, we tested oviposition deterrence and insecticidal effects of such substances. Female D. suzukii flies were exposed to treated blueberries under laboratory conditions for 24 hours. Kaolin, linoptilolite, clinoptilolite + Heliosol (pine-oil  based wetting agent) and calcium carbonate significantly reduced...

• Lower accumulation of copper in the soil.  • Less damage to microorganisms in the soil.  • Potential saving in costs of spraying agent.  • Improved distribution of spraying agent over the required period of treatment until exhaustion of the permitted maximum quantity.  Practical recommendation  Adapting dosage to state of infestation: As long as there is no infestation in a radius of 50 km, refrain from  treating. Observe national information and alert services. As soon as the first case of infestation in the region is reported, protect potatoes with 200 to 250 g of pure copper per hectare. If potatoes in your own or neighbouring fields are afflicted by leaf blight, increase the dosage to 800 g and do not wait longer than a week in between treatments....

Breeding for mycorrhizal symbiosis: focus on disease resistance
Provedor de dados: 21
Autores: Hohmann, Pierre; Messmer, Monika.
Modern plant breeding can no longer afford to ignore the interaction between plants and microbial key players. Increasing evidence suggests (i) that the expression of many plant traits (such as nutrient use efficiency or tolerances against biotic and abiotic stresses) is mediated by beneficial microorganisms and (ii) that there is an exploitable genetic base for the regulation of symbiotic relationships. Arbuscular mycorrhizal fungi (AMF) play a key role in many of these trait expressions. While much is known about their ability to mobilise nutrients (especially phosphorus), the complex mechanisms of AMF-mediated disease resistance have only started to become apparent within the past decade. Besides competition for root space and resources, AMF also have...

Autores: Berkelmann-Löhnertz, B.; Junge, H.; Kast, W.K.; Wolf, G.A.
Im vorliegenden Projekt wurde der Einsatz bakterieller Antagonisten als Kupferersatz zur Bekämpfung von Plasmopara viticola, dem Erreger des Falschen Mehltaus der Weinrebe, im ökologischen Weinbau optimiert. Mit Hilfe von Dual-Kultur-Tests wurden sechs bakterielle Antagonisten aus vorhandenen Antagonisten-Stammsammlungen selektiert (Testpilze: Pythium ultimum; Phytophthora infestans). Mittels Blattscheiben-Test im Labor konnte mit den ausgewählten Isolaten eine Befallsreduzierung auf unter 5 % Befallsstärke erzielt werden. Der Befall in der unbehandelten Kontrolle schwankte je nach Ansatz zwischen 19 % und 35 %.     Unter Gewächshausbedingungen zeigte sich an Topfreben ebenfalls eine gute biologische Wirksamkeit gegen den Schadpilz. Die Kontrollpflanzen...

Kartul on üheks armastatumaiks kultuuriks nii meil kui maailmas. Teda on läbi aegade peetud teiseks "leivaks" ning tänapäeval ei kujutaks meist keegi ette oma toidulauda, kust puuduks kartul (Eremeev jt., 2012). Hea eelkultuurina teraviljadele sobib ta hästi ka päikesepinnalistesse külvikordadesse. Kartulit saab edukalt kasvatada maheviljeluslikus suletud tsükliga tootmisüksustes, kus on võimalik kasutada loomapidamisest  tekkivad sõnnikut (Järvan ja Edesi, 2012). Maheviljeluslikus külvikorras on oluline osa vahekultuuride kasvatamisel. Põhikultuuride kasvatamise vahepealsel ajal vahekultuurid kaitsevad ja rikastavad mulda toitainetega ning suruvad alla umbrohtumust.

There is a lack of appropriate plant protection methods against strawberry blossom weevil (SBW) not only in organic plantations, but also in plantations, where IPM is used. European tarnished plant bug (ETPB) is not currently recognized as a pest in Latvian strawberry plantations, because the visual defects made by bugs are not important for Latvian consumers.  Cross vane bucket traps and sticky stake traps were the most effective for trapping SBW in Latvia. These traps, where the lure was positioned at the top of cross vanes, were also the most effective for capturing ETPB.

Autores: Döring, Thomas; Pautasso, Marco; Finckh, Maria R.; Wolfe, Martin.
Plant health is a frequently used but ill-defined term. However, there is an extensive literature on general health definitions and health criteria in human medicine. Taking up ideas from these philosophical debates, concepts of plant health are reviewed and a framework developed to locate these concepts according to their position in several philosophical controversies. In particular, (i) the role of values in defining plant health in a naturalist versus a normativist approach; (ii) negative and positive definitions of plant health; (iii) reductionist versus holistic perspectives; (iv) the focus on functionality versus resilience, i.e. the ability of the plant to perform under stress with or without human interference; (v) materialist versus vitalist...

Technique of pneumatic pest control – analyses and a new device
Provedor de dados: 21
Autores: Schäfer, Winfried.
Pest control in organic production of berries, potatoes and vegetables usually employs spreading technique of registered phytopharmaceutical agents. This technique may be supported or even replaced by pneumatic pest control. Pneumatic pest control means suction of pest using a vacuum device similar to a home vacuum cleaner. Up to now there is no evaluation of pneumatic pest control available from an agricultural engineering point of view. This paper concerns the following questions: Which techniques of pneumatic pest control are available and how may these techniques be improved in terms of technical and physical parameters? Based on the answers a new device design is presented.

Reduction of spore spread of common bunt (Tilletia tritici) via combining equipment
Provedor de dados: 21
Autores: Kristensen, Lars; Borgen, Anders.
The disease common bunt (Tilletia tritici syn. T.caries) has become a more frequent problem in Europe during the last 15 year. In organic farming, common bunt causes serious problems for seed producers, and many seed lots are discarded due to contamination with Tilletia tritici. Due to the biology of Tilletia tritici, with spores loosely attached to the surface of the grain, there is a risk that spores can be disseminated via grain handling equipment, including combine harvesters. Preventive efforts should focus on the role of grain handling equipment, and how the fungus life cycle can be broken. We have investigated the dissemination of spores via the combiner after harvesting infected fields. We conducted six trials over three years, counting the number...

Efficacy of Armicarb (potassium bicarbonate) against scab and  sooty blotch on apples
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Schärer,  Hansjakob; Refardt, Matthias.
A novel formulation of potassium bicarbonate (Armicarb) was evaluated in 2004 and 2005 as  agent against apple scab (3 field trials) and sooty blotch (2 field trials). Armicarb controlled  scab equally well as the reference treatments sulphur and copper. Armicarb showed also  excellent activity against sooty blotch. However, potential side-effects such as lenticell spot  development need further investigation. At present, potassium bicarbonate is considered by  the Swiss registration authorities as non-toxic to humans and in consequence, no residue  levels have been specified. Armicarb has very interesting properties as a plant protection  agent and its composition and risk profile are expected to fulfil the IFOAM standards for  acceptance of novel plant...

Understanding earwig phenology in top fruit orchards
Provedor de dados: 21
Autores: Gobin, B.; Peusens, G.; Moerkens, R.; Leirs, H.
Earwigs, Forficula auricularia, are key generalist predators to a variety of orchard pests.  However, numbers of earwigs have declined in both organic and IPM orchards in recent  years. Both Integrated and Organic fruit growers have tried to re-establish earwig  populations, thus far with little success. To understand earwig population dynamics and to  find measures to increase natural orchard populations, we conducted a detailed  phenological survey of earwigs in orchards. Earwigs were sampled while sheltering during  daytime in artificial refuges. They move into the trees from the third nymph stage onwards.  In most orchards, a small second brood is produced in summer, and this has a positive  impact on population size in fall. We see only minor...

Manici, L. M., Kelderer, M., Caputo, F., Nicoletti, F., De Luca Picione, F. and Topp A. R. 2015.   Replant disease of fruit tree orchards has a multifactorial etiology, mainly due to the decline in soil biodiversity along with an increase in root rot pathogens, which can be principally countered with appropriate cropping practices. Therefore, a study on the impact of cover crops on plant health of young fruit trees in long-term orchards was performed. Bioassays were performed over two consecutive growing cycles using soil from a multigeneration apple orchard affected by replant disease. First, a cycle was performed with three cover crops (alfalfa, barley, marigold) and apple rootstock plantlets; at the end, the above-ground part of the plant was removed...

Diverse fertility building leys in arable rotations
Provedor de dados: 21
Autores: Bliss, Katie; Measures, Mark.
The results of a three year study in the UK suggest that there are several advantages to more complex mixtures;   • Greater resilience to variable conditions  • Combine early and late weed suppression • Slower decomposition on incorporation  • Extends forage availability for key insect pollinators  • Generally achieve higher forage yields  • Potential for higher subsequent crop yields.   Practical recommendation   • There are a number of plant characteristics that have an impact on nitrogen release and mobilisation, namely C:N ratio, lignin and polyphenol content which result in slower N release and lower N losses or better N utilisation.  • Including grass species in the mix takes up the N fixed by the legumes and reduces the free N in the soil; the...

Strategies for regulation of seed borne diseases in organic farming
Provedor de dados: 21
Autores: Borgen, Anders.
Common bunt caused by the fungus Tilletia tritici (syn. T.caries) is one of the most devastating plant diseases in wheat. In conventional agriculture the disease is controlled exclusively by fungicide seed treatment, but in organic farming these fungicides are not accepted. Previous studies in India have shown that seed treatment with plant extracts of Canabis sativa, Eucalyptus globulus, Thuja sinensis and Datura stramonium was fully effective against the disease under field conditions. Later, in vitro studies have shown that also germination of spores of the Karnal bunt pathogen (Neovossia indica) could be prevented by these plant extracts. The experiment was repeated in Denmark with extracts from the same species grown in Denmark, which has climate...

Autumn applications of sulphur – a new approach to control the pear leaf blister  mite Eriophyes pyri
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
The pear leaf blister mite can cause severe damages to pear trees. By their hidden way of living inside  the leaf blisters, the mites are protected from plant protection agents. Until now, oil treatments  in early spring, when the mites leave their hibernation sites and invade the young leaves, are the  only possibility to control these mites. Because of the low temperatures during this period (February/  March) the efficacy of pesticides is often not reliable. The aim of this study was to assess the effects  of sulphur applied after harvest at the time, when mites are leaving the blisters and migrate to  the hibernation sites. The treatments were applied shortly after harvest to benefit from the mild temperatures  in September. Visual controls in...

Lutte contre le Bremia de la laitue sous abri: tests de produits alternatifs au cuivre
Provedor de dados: 21
Autores: Lambion, Jérôme.
Le mildiou de la laitue (Bremia lactucae) est la maladie la plus redoutée sur cette espèce, notamment en culture biologique d’hiver sous abris. En Provence, les dégâts sont très importants, parfois dès la pépinière, et entraînent de fortes pertes financières. Cette situation est due à deux facteurs principaux : d’une part au contournement récurrent des résistances génétiques par de nouvelles souches de Bremia (25 races déterminées à ce jour), et d’autre part à la faiblesse des méthodes de lutte biologique possibles contre ce champignon. Pour faire face à ce manque de moyens de lutte, le GRAB a testé en 2004 différentes préparations susceptibles d'être utilisées en Agriculture Biologique.

The assessment of some crop management methods in barley and potato seed production for organic farming
Provedor de dados: 21
Autores: Skrabule, Ilze; Legzdina, Linda.
The aim of investigation was to evaluate different crop management methods in production of qualita-tive seed material of barley and potato. The late blight damages on potato leaves depended on genotype resistance; more resistant variety had less damaged leave area. The genotype determined potato yield and average weight of tubers. The tuber pre-sprouting before planting accelerated plant germina-tion and promoted formation of bigger yield tubers. Presprouting influence on yield was not observed. Higher yield and smaller tuber weight was obtained if seed material was planted with shorter distance. Influence of planting distance on late blight develop-ment on leaves was not observed. The best yielding barley genotype was breeding line PR-2797, which is...

Although since 1924 the biodynamic hornpreparations (cowhorn manure and cowhorn  silica) have been practically used and investigated in several doctoral theses, hardly  any attention has been paid at the scientific evaluation and explanation of their effects.  The results of experimental studies with the preparations are summarized. To  understand their mechanism, an ecological and ecophysiological focus can be used. It  shows that at several levels of the agro-ecosystem regulative mechanisms can be  found. Bacterial and hormonal effects are found, if the preparations are analysed.  These scientific results should be understood and discussed in relation to the  anthroposophical or esoteric understanding of the biodynamic preparations.

Autores: Wibe, Atle.
For tuning up sustainable organic strawberry production new measures in pest management needs to be developed. Both pest insects and pathogenic fungi reduces yields and fruit quality. Present study shows that mass trapping of strawberry blossom weevils by using volatile baited traps is not an efficient measure in an established field. However, in a new study traps will be combined with fencing of the field with insect net. There will also be a study on the effect of using ozonated water as a measure to prevent the fungus related disease grey mould to develop.

Organic plant production is currently challenged by several pressure factors. Along with perennial problems such as weed control, climate change is threatening to affect crop production through increasing weather variability. Plant breeding is a crucial factor in creating organic crop production systems that can better cope with such interacting stresses and producers need crop varieties with (a) good resistance against pests and diseases, esp. seed borne diseases; (b) the ability to react to environmental, esp. climatic variability; and (c) high competitiveness against weeds.

Kriterien zur Stickstoffeffizienz moderner Winterweizensorten  und deren Eignung für low-input Anbausysteme
Provedor de dados: 21
Autores: Schneider, David; Charles, Dr Raphaël; Mascher, Dr Fabio.
Nitrogen deficiency is one of the most important reasons for reduced quality and yield  stability in wheat production under low-input conditions. The present project intends to  develop criteria allowing to find varieties that are adapted for low-input agricultural  conditions. Therefore, yield and nitrogen uptake and use dynamics of eleven modern  wheat varieties have been studied under low and high input conditions on a long term  field experiment in Changins. This preliminary report shows that nitrogen efficiency  defined as yield per available nitrogen is a useful criterion to distinguish nutrient  efficiency under high nitrogen conditons but not when nitrogen is lacking. In further  studies we will focus on backing quality as a potential indicator for...

Réduction des attaques du collet sur salade : test de plusieurs produits alternatifs - compte-rendu d'essai 2009
Provedor de dados: 21
Autores: Lambion, Jérôme.
La fonte des salades, causée par une attaque de pathogènes au niveau du collet, est un dégât très fréquemment rencontré dans les cultures d'hiver en zone méditerranéenne ; les pertes économiques peuvent être très importantes. Cette fonte peut être provoquée par Botrytis cinerea et/ou par Sclerotinia sclerotiorum. Sclerotinia est un champignon se conservant plusieurs années dans le sol sous forme de sclérotes. Il est particulièrement virulent sur salades, mais il est également inféodé à de nombreuses autres espèces maraîchères. Il est favorisé par de nombreux facteurs : salinité et teneur élevée en azote du sol, cultures intensives et rotations limitées, stress climatiques (périodes de gel, notamment à la reprise : jeunes plants non endurcis), irrigations...

Provedor de dados: 21
Autores: Köhl, Jürgen; Heijne, Bart; Hockenhull, John; Pedersen, Hanne Lindhard; Trapman, Marc; Eiben, Ute; Tamm, Lucius.
The objective of REPCO is to contribute to the replacement of copper fungicides in organic agriculture by  new measures for control of downy mildew (Plasmopara viticola) in grapevine and scab (Venturia inaequalis)  in apple. Both major European organic crops strongly depend on copper fungicides. Permitted amounts will  be reduced stepwise during the following years (Council Regulation (EEC) 2092/91, Annex II) to avoid  environmental risks. In European countries where copper fungicides are already out of use, production of  organic apples suffers severe economical problems because of insufficient scab control.  Potentiators of resistance, organically based fungicides and biocontrol agents are screened and evaluated in  apple. Effects of crop management...

Suppression of pathogens causing foot rot of pea by application of yard waste compost
Provedor de dados: 21
Autores: Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R.
Legume foot and root diseases are mostly caused by broad host-range pathogens. These cannot be managed by rotations alone as often cover crops also are susceptible. Organic amendments such as high quality composts are key management tools for dealing with pathogen pressure. A pot experiment under controlled conditions was carried out to evaluate the suppressive potential of Yard Waste Compost (YWC) against foot rot disease of pea caused by Mycosphaerella pinodes, Phoma medicaginis, Fusarium solani f. sp pisi and F. avenaceum. The spring pea Santana and winter pea EFB33 were grown in sterile sand or sand amended with 3.5 % or 20 % (v/v) YWC as a substrate for three weeks. They were either inoculated at sowing with spore suspensions or left uninoculated....

Auxin-mediated relationships between apple plants and root  inhabiting fungi: impact on root pathogens and potentialities  of growth-promoting populations.
Provedor de dados: 21
Autores: Manici, L.; Kelderer, M.; Caputo, F.; Mazzola, M.
This study aimed to elucidate the relationship between plant hosts and root-colonizing fungi recovered from apple orchard soils that had been replanted over multiple generations. Functional relationships of three groups of filamentous fungi (Ceratobasidium sp., Cylindrocarpon-like group and Fusarium acuminatum) with apple rootstocks were evaluated  in plant growth bioassays. The Cylindrocarpon-like group and Ceratobasidium sp. showed a relationship with the host plant varying from pathogenic to commensal through to mutualistic for the latter group, while that of F. acuminatum tended to be mutualistic. Seven fungal isolates of each group, which induced the highest plant growth in bioassays, were evaluated for auxin (IAA) and gibberellin (GA3 and GA4)...

Vergleich verschiedener Kupferformulierungen bei gleicher CU-Aufwandmenge gegen Rebenperonospora
Provedor de dados: 21
Autores: Kast, Walter K.
Kupferhaltige Präparate sind bisher eine wichtige Basis für die Peronosporabekämpfung im ökologischen Anbau. Bereits sehr geringe Kupferaufwandmengen haben eine sehr gute Wirkung gegen Rebenperonospora (siehe Kast 1996). Nach dem derzeitigen Stand des Anhangs 2 der EU-Verordnung 2092/91 sind kupferhaltige Präparate allerdings nur noch bis zum 31.03.2002 zulässig. In Deutschland lauft die Zulassung aller Kupferpräparate Ende des Jahres 2000 aus. Inwieweit die Zulassungen verlängert werden können, ist zurzeit offen. Das Schwermetall Kupfer reichert sich bei kontinuierlicher Anwendung allmählich im Boden an und belastet insbesondere auch die Ökosysteme der Oberflächengewässer. Auch bei einer Verlängerung der Zulassungen muss es deshalb im Interesse des...

Studies of interaction between pathogens
Provedor de dados: 21
Autores: Vollmer, Jeanette; Østergård, Hanne.
A fundamental ecological observation is that activity of any organism affects the environment in which it lives. This has consequences not only for that organism or members of that species, but for other species inhabiting the same environment. It means that the dynamics of a population of a species living in a given environment cannot be evaluated without considering other species in the same environment and the interactions with and between these. Two species may experience several potential interaction types, e.g. competition (A and B have a negative effect on each other), mutualism (A and B have a positive effect on each other) or exploitation (A has positive effect on B, while B has negative effect on A), which may be either direct or indirect.

Autores: Spornberger, A.; Steffek, R.; Stich, K.; Scheiblauer, J.; Altenburger, J.; Gosch, C.; Halbwirth, H.; Jezik, K.
Soil-borne pathogens, above all Verticillium sp. cause plant losses and yield decreases in many Austrian  strawberry fields, also in organic farming systems; in a research project possibilities to resolve this problem  were examined. In a field trial, which was started 1998, organically managed and differently fertilized plots  (green compost, manure, hornchips) were compared to an unfertilised control plot and to two mineral  fertilized and conventionally treated plots; the differences in field characteristics of strawberries in 2004 and  2005 were low, but differences in storage and biochemical characteristics could be seen in 2005. Some new  cultivars tested as alternative to the very sensitive 'Elsanta' planted in 2005 on several farms showed a  higher...

Seed separation to control barley loose smut (Ustilago nuda)
Provedor de dados: 21
Autores: Borgen, Anders.
The main control of loose smut is the selection of varieties that flower with a closed flower. Seed lots infected by loose smut can be treated with fungicides, and this is regularly used in conventional agriculture. Environmental concern has focused on the use of pesticides for seed treatment, and in organic farming pesticides cannot be used at all. Hence, there is a growing demand for non-chemical measures to control seed borne pathogens like loose smut.    The flowers in the top of the barley head normally flowers more openly than the flowers in the centre or the bottom of the head, and the seed developed in these flowers are statistically smaller. It is also possible that the presence of mycelium in the embryo reduces the filling of the seed. Removal of...

Abstract  The woolly apple aphid (Erisoma lanigerum Hausm.) has been recognised for some years as a serious pest in organic fruit growing where they may cause severe economic damage due to a lack of control strategies. Based on preliminary results a new project has been started in 2007 testing combinations of releasing earwigs and oil applications in order to develop an on-farm control strategy. In this paper we present preliminary results of the first year of the project´s field trials. They showed good efficacies for applying oil preparations by brush. The efficacy of releasing earwigs depended on the infestation intensity.

Autores: Titze, Andreas; Jakobs, Marion.
The influence of different fertilization (NPK, PK, 0) and cutting frequency (2, 4 or 6 cuts) on dry matter yield, feeding value and plant composition of the sward of fen soil permanent grassland was investigated over five years. A randomizedblock design with plots was used, with three blocks. Effect of N application (NPK with 140 kg N/ha per year) was very low, because of a high N-mineralisation rate in the fen soil. Under intensive management (4 or 6 cuts) the PK-treatment (without N) reached a high feeding value as well as a high dry matter yield. This result may be very important for organic grassland farming on fen soils. Deficiencies in soil nutrients (0-treatment), especially potassium, reduce dry matter yield, high quality forage plants content of...

Hahkhallitus (Botrytis cinerea Pers.) on aedmaasikal (Fragaria × ananassa Duch.) suuri saagikadusid põhjustav seenhaigus, mille tõrjel sünteetiliste taimekaitsevahenditega ilmneb mitmeid negatiivseid kõrvalnähte nagu kiire resistentsuse kujunemine ning pestitsiidijääkide kogunemine viljadesse ja keskkonda,  mistõttu on üha enam hakatud eelistama bioloogilisi tõrjemeetodeid. Üheks võimaluseks on viia biopestitsiid maasikaõiteni kasutades meemesilasi (Apis mellifera L.), nimelt lisatakse vastav pulbriline preparaat mesilastaru küljes olevasse dispenserisse, mida läbides jääb preparaat mesilase kehakarvade külge ja viiakse toidukorje käigus aedmaasika õitele.

Kupferfreier Anbau von Biokartoffeln
Provedor de dados: 21
Autores: Gelencsér, Tobias; Dierauer, Hansueli.
Die getesteten Sorten schnitten im 2018 alle recht gut ab, vor allem auch wegen der ausbleibenden Regenfälle und dem geringen Krautfäule-Druck. Dadurch konnten die Sorten leider erneut nicht auf das Hauptkriterium Krautfäulewiderstandsfähigkeit hin geprüft werden. Es wird deshalb empfohlen, die Sorten im Folgejahr erneut zu testen.  Die agronomischen Eigenschaften der Sorten waren zufriedenstellend, mit den Stärken und Schwächen der einzelnen Sorten sollte man leben können. Was jedoch zum Ausschlusskriterium führen könnte, ist das Aussehen und der Geschmack der Knolle. Gerade Acoustic, die recht stabil zu sein scheint, hat unvorteilhafte Knollenform und -farbe. Allians wird hingegen mit der regelmässigen, länglichen Form und dem tiefgelben Fleisch eher den...

Fruchtresistenz von Tomaten gegen P. infestans
Provedor de dados: 21
Autores: Butz, Andreas F.; Finckh, Maria R.
Resistance of tomato fruits to Phytophthora infestans  Late blight, caused by Phytophthora infestans (Mont) de Bary, is one of the important  diseases in organic potato and tomato production. While some information on foliar  disease resistance of tomatoes is available, virtually no information exists on the  relation of leaf to fruit resistance.  The central parameters of the infection chain, incubation and latency period were  determined for 40 tomato varieties using three isolates of P. infestans. A total of 2858  fruits were drop inoculated in the lab and assessed daily for symptoms or sporulation  for 16 days.  There were significant variety by isolate interactions for incubation period, latency  period and the interim time suggesting race specific...

Autores: Schmehe, Ben; Spieß, Hartmut.
Aktuell zugelassene deutsche und österreichische Hafersorten (Stand 2010) wurden in den Jahren 2009 und 2010 auf Flugbrandresistenz getestet. Da derzeit in der offiziellen Sortenzulassung in Deutschland keine Prüfung auf Flugbrandresistenz stattfindet, sind die präsentierten Ergebnisse eine wichtige Ergänzung zu den aktuellen Sorteninformationen aus den Öko-Landessortenversuchen. Die Hafersorten wurden in Anlehnung an die Unterdruck-Inokulationsmethode von Nielsen (1976) bei -800 hPa für 10 Minuten in einer Suspension aus destilliertem Wasser und 1 g/l Flugbrandsporen inokuliert.

Vorblütebehandlungen mit Kaolin gegen den Gemeinen Birnenblattsauger (Cacopsylla pyri)
Provedor de dados: 21
Autores: Daniel, Claudia; Wyss, Eric.
The European pear sucker Cacopsylla pyri (L.) (Homoptera: Psyllidae) – one of the main pest insects in pear production – is commonly controlled by spraying broad-spectrum insecticides, which may have serious side-effects on beneficial arthropods. Recently, a new approach to fruit pest management has arisen in the form of processed-kaolin particle film technology (product name Surround® WP). The white kaolin particle film repels insects without killing them. Therefore, side effects on beneficial arthropods are expected to be low. This new approach triggered the present study to control C. pyri. In spring 2003 a small-plot field trial was conducted to assess the impact of pre-flowering kaolin treatments on the first generation of C. pyri. Multiple...

Promoting production and use of organic potatoes in Northern Ostrobothnia, the northernmost agricultural area in Europe
Provedor de dados: 21
Autores: Hiltunen, L H; Vorne, V; Virtanen, E; Degefu, Y; Korhonen, K; Muilu, T; Tausta-Ojala, M-L.
The demand for organic products is increasing in Finland. Potato is an important part of the Finnish diet with around 60 kg of potatoes per person consumed annually. The demand for organic potatoes and potato products is also increasing. However, currently less than 2 % of the potato crops are grown organically, and neither the volume nor the quality meets the expectations of the consumers and professional kitchens. Organic potato production faces many challenges including lack of suitable cultivars and fertilisers and difficulties with disease control, all of which may contribute to low yields in organic production. The objective of this on-going study is to promote the production and use of organic potatoes in Northern Ostrobothnia, the northernmost...

Autores: Krebs, Heinz; Musa, T.; Forrer, Hans-Rudolf.
In indoor trials with potted potato plants and in micro- and small plot field trials, prepa-rations of Frangula alnus controlled Phytophthora infestans leaf blight significantly bet-ter than other antifungal plant preparations and the copper free reference Mycosin®. However, under field conditions the efficacy of the buckthorn bark preparation (BBP) was drastically lower than in the indoor trials. Therefore and in order to avoid environ-mental pollution with solvent of the plant extract, we developed a procedure to apply finely ground plant material as suspension directly on the potato plants without any ex-traction. The efficacy of BBP applied as suspension was significantly higher than those of ethanolic extracts. To improve the weather stability or the...

Combatting Cocoa Swollen Shoot Virus Disease: What do we know?
Provedor de dados: 21
Autores: Andres, Christian; Gattinger, Andreas; Dzahini-Obiatey, Henry K.; Blaser, Wilma J.; Offei, Samuel K.; Six, Johan.
Cocoa Swollen Shoot Virus Disease (CSSVD) is one of the major factors limiting cocoa (Theobroma cacao L.) productivity in West Africa. The only cure for CSSVD is to cut out visibly infected trees and the official eradication campaign in Ghana has cut out more than 200 million trees since 1946. 80 years of research on preventive control measures have mainly focused on resistance breeding, mild strain cross-protection (inoculation of cocoa seedlings with a mild strain of the virus to protect against the severe strain) and control of mealybug vectors. Meanwhile, diversification measures such as agroforestry (for shading) or barrier (strip) cropping have received less attention. Despite promising results, CSSVD is more prevalent in the field than ever before....

Quassia, an Effective Aphid Control Agent for Organic Hop Growing
Provedor de dados: 21
Autores: Weihrauch, Florian; Schwarz, Johannes; Engelhard, Bernhard.
In the first three decades of the 20th century, quassia extract was widely used in hop growing as a chemical agent to control Phorodon humuli and other insect pests. In the first years of the 21st century this compound was rediscovered by German organic hop growers. In several efficacy trials conducted during five field seasons, quassia pro¬ducts proved to be effective control agents for P. humuli in organically grown aroma cultivars. A systemic variant developed by painting a suspension of quassia extract to the bines was the best method of application. This method proved not only to be very effective, but was also best from an environmental point of view. The optimal systemic application rate was determined as 24 g/ha of the active ingredient quassin. In...

The side effects of lime sulphur on predaceous arthropods, i.e. Typhlodromus pyri, and other leaf occupying arthropods
Provedor de dados: 21
Autores: Daniel, Claudia; Häseli, Andreas; Weibel, Franco.
Conclusions and further studies     The significant reduction of T. pyri and of larvae of predaceous gall midges, the complete loss of mite-diversity and the possible enhancement of P. ulmi and other harmful mites (i.e. C. vitis) are clear disadvantages of lime sulphur. Densities of T. pyri between 0.5 and 1 mite per leaf as mentioned to be necessary for controlling harmful mites (BOURQUIN 1989, FORTMANN 1993, HARZER 1993, KARG 1992, KOHLER ET AL. 1991), were never reached in lime sulphur treatment, while the untreated control always showed densities above this value.     On the other hand low densities of predaceous mites are quite normal in intensively sulphur treated, biological orchards and are often replaced by other mite predators, like predatory...

Biodiversity enhancement and utilization - Pest control in brassicas
Provedor de dados: 21
Autores: Luka, Henryk; Barloggio, Guendalina.
In cabbage fields parasitoid wasps (Hymenoptera) use the eggs or larvae of pest butterflies and moths for their own reproduction, ultimately killing them, playing an important role in the biological plant protection strategy. An efficient way to promote this parasitoids in the crop field is to provide them with flower strips as well as companion plants, e.g. cornflower (Centaurea cyanus), that will provide them with food (nectar) and shelter. Between 2007 and 2010 we conducted experiments to test the olfactory attractiveness of different flowers as well as the influence of their nectar on the regulation of the cabbage moth (Mamestra brassicae) as well as on the lifespan and parasitation performance of its antagonists (egg and larval parasitoids).

Die Nachbaukrankheit beim Apfel. Ein undurchsichtiges Problem wird näher beleuchtet
Provedor de dados: 21
Autores: Rhümer, Thomas.
Die Zusammenhänge und Prozesse, die sich im Boden abspielen, sind meist nicht leicht durchschaubar und nur schwer zu erforschen. Genauso verhält es sich auch beim Phänomen der Nachbaukrankheit beim Apfel. Wird ein Apfelbaum nach dem anderen am selben Platz gepflanzt, so wächst er immer schwächer, die Ertragsleistung nimmt ab. Früher hat man häufig von „Bodenmüdigkeit“ gesprochen, heute weiß man, es handelt sich um biologische Ursachen, daher ist die Bezeichnung „Nachbaukrankheit“ oder im Englischen „Apple replant disease“ treffender.

Autores: HAN, Hui; GUO, Ruihua; YANG, Yubao; LI, Ji.
This study was based on a long-term field trials of three different vegetable cropping systems (organic, low-input and conventional) in greenhouse which was initiated in 2002 at Quzhou Experimental Station of China Agricultural University, Hebei Province. The apparent nitrogen budget which equals to N input (nitrogen of fertilizer, transplants and irrigation) minus N output (nitrogen of the eggplants) was compared to provide the reference for the development of high yield and sustainable cropping system. The main conclusions were as follows: The total input of nitrogen in the organic, low-input and conventional systems was 1 150 kg·hm2, 1 182 kg·hm2 and 1 433 kg·hm2, respectively. The total nitrogen uptake by plants was 178 kg·hm2, 135 kg·hm2, 116 kg·hm2,...

Entwicklung von „near isogenic lines“ als Basis zur nachhaltigen Züchtung von Basilikum-Sorten mit Resistenz gegen den Falschen Mehltau
Provedor de dados: 21
Autores: Grosch, Rita; Hohe, Annette; Farahani-Kofoet, Roxana Djalali; Römer, Peter.
Die Produktion von Basilikum-Frischware erfolgt in hoher Intensität in spezialisierten Betrieben. Der Anbau ist seit einigen Jahren regelmäßig durch das Auftreten des Falschen Mehltaus, verursacht durch den Erreger Peronospora belbahrii, bedroht, für deren Kontrolle derzeit keine geeigneten Verfahren zur Verfügung stehen. Eine umwelt-, verbraucher- und produzentenfreundliche Strategie, dem Auftreten des Falschen Mehltaus entgegen zu wirken, ist der Anbau von resistenten Sorten. In einem voraus-gegangenen Projekt konnte eine Resistenzquelle bzw. resistenter Basilikumgenotyp aufgefunden wer-den, die genutzt wurde, um die Resistenz in den vom Verbraucher bevorzugten Genoveser-Typ einzukreuzen.

Reduzierung kupferhaltiger Pflanzenschutzmittel im ökologischen Weinbau: Untersuchungen zu innovativen Kupferformulierungen mit hohem Reduktionspotential und Entwicklung von Strategien zu deren gezielter Anwendung gegen die Rebenperonospora
Provedor de dados: 21
Kupferpräparate sind im ökologischen Weinbau derzeit unverzichtbar, um die Weinrebe vor Schäden durch die Rebenperonospora zu schützen. und Ertrag und Qualität zu sichern. Aufgrund der ökotoxikologisch Wirkung des sich schnell im Boden anreichernden Kupfers muss der Eintrag von Kupfer auf ein umweltverträgliches Niveau reduziert werden.  Als Kontaktmittel besitzen kupferhaltige Pflanzenschutzmittel gegen die Rebenperonospora nur ein sehr begrenztes Wirkungsfenster, das sehr wahrscheinlich zwischen dem Anheften der Sporangien und dem Auskeimen der Penetrationshyphe liegt.   Eine Möglichkeit, den Eintrag von Kupfer auf ein umweltverträgliches Maß zu minimieren, ist die Entwicklung neuer Formulierungen mit gezielter Freisetzung der Cu-Ionen etwa durch...

Resistenzzüchtung für den Ökologischen Landbau bei Getreide
Provedor de dados: 21
Autores: Miedaner, T.; Fischer, K.; Merditaj, V.
Fazit  Auch im Ökologischen Landbau gibt es Forschungsbedarf für Resistenzzüchtung, die Schwerpunkte sind aber teilweise andere als im konventionellen Bereich.   Bei Ährenfusariosen kann der Ökologische Landbau die vielfältigen Bestrebungen der konventionellen Züchter nutzen, in dem er die Resistenz bei der Sortenwahl berücksichtigt. Bereits mittelanfällige Sorten könnten hier einen ausreichenden Schutz bieten.  Bei Mutterkorn ist dringender Handlungsbedarf bei Roggen geboten, da hier mit Kulturmaßnahmen wenig Fortschritte zu erzielen sind. Die genetischen Unterschiede lassen gute Selektionsmöglichkeiten erwarten. Bei Triticale scheint aufgrund der bisherigen Ergebnisse wegen des geringen Befalls keine Züchtung erforderlich zu sein.   Anders sieht es bei...

Mitigation of subsoil recompaction by light traffic and on-land ploughing. II: Root and yield response
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.; Jørgensen, M.H.; Thorup-Kristensen, K.
Plough pans have been shown to severely hamper root development, limit rooting depth and reduce crop yields. We evaluated the effect of plough pan compaction on root and yield response for a winter wheat in a field trial conducted in two neighbouring fields (B3 and B4) on a sandy loam. Plots were mechanically loosened to a depth of 35 cm in 1997 (B3 and B4) and again in 1998 (only B4). Perennial grass/clover was grown with limited traffic intensity in 1998-1999 and 1999-2000 for B3 and B4, respectively. The perennial grass/clover was ploughed under in spring 2000 (B3) and spring 2001 (B4) and oats established. After harvest of oats, winter wheat was established. Recompaction treatments were applied to the mechanically loosened plots in 2000 and 2000+2001...

In 2005 initial experiments were carried out to control Rhagoletis cerasi with bait sprays. We used GF-120 fruit fly bait which contains Spinosad and NeemAzal®-T/S mixed in a sugar-yeast hydrolysate solution. 30 ml of bait sprays were applied on single cherry trees in field cages, where we released a defined number of cherry fruit flies. One experiment with GF-120 resulted in a reduction of fruit infestation of 96 % compared with the control. In other trials with GF-120 and Neem bait the effect on the cherry fruit fly population was monitored. After 24 hours GF-120 in a 5 % and 20 % solution led to a high reduction of flies (efficacy 85 %), whereas NeemAzal®-T/S in a 5 %, 10 %, and 20 % solution only resulted in efficacies between 34 % and 42 %.

Approaches for field assessment of resistance to leaf pathogens in spring barley  varieties
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Hovmøller, M.S.; Østergård, H.
The resistance of spring barley varieties to powdery mildew, leaf rust, leaf scald and net blotch was characterized by using results from inoculated small-plot nurseries and larger survey plots subject to natural infection. The experiments were conducted in different environments. Both trial types often yielded complementary results with respect to the ranking of varieties suggesting that a recommended variety characterization should include both naturally infected survey-type trials and nursery trials in which the most relevant pathogen isolates and/or isolate mixtures or populations are used for inoculation. Average and median values of the diseased leaf area of a variety were highly correlated with each other and with the genotype main effect determined...

Mode of action of lime sulphur against apple-scab (Venturia inaequalis)
Provedor de dados: 21
Autores: Zemmer, Franziska; Marschall, Klaus; Kelderer, Markus; Zelger, Roland.
Since lime sulphur was accepted in the annex 2b of the European Regulation 2091/92, more and more fruit growers use it to control apple scab in organic orchards. Field trials were carried out at the Research Centre Laimburg to evaluate stop and curative treatments with the aim to reduce the number of treatments and improving their efficacy. In this diploma thesis microscopic observations were performed for a better understanding of the mode of action of lime sulphur on apple-scab. The results showed that lime sulphur can stop the scab infection until the formation of the appressorium. If the infection proceeds to the formation of the primary stroma, the efficacy of the treatments with lime sulphur was insufficient.

We investigated the virulence of three European isolates of the entomopathogenic fungus (EPF) Metarhizium anisopliae against three wireworm species which are important pests of arable crops and vegetables in Europe: Agriotes lineatus, A. obscurus and A. sputator. In laboratory experiments, up to 90 % of the wireworms were killed by the fungus, depending on the fungal isolate and the wireworm species. Speed of kill was generally low with first wireworms showing unambiguous signs of fungal disease after two to three weeks. Maximum mortality rates were reached after six to eight weeks post inoculation. The next steps of this investigation will be to determine the most suitable fungal isolate and the validation of the laboratory results under greenhouse and...

Mit Spätsaat und Netz gegen den Möhrenblattfloh
Provedor de dados: 21
Autores: Koller, Martin; Lichtenhahn, Martin.
Auf Karottenfeldern, die nahe bei einem Nadelwald stehen, kann der Möhrenblattfloh grosse Schäden anrichten. Das erwachsene Insekt überwintert auf Fichte, Tanne oder Föhre/Kiefer/Dähle und wandert von dort zwischen Ende Mai und Anfang Juli in die Karottenfelder ein, wo es junge Möhrenpflanzen ansticht. Die Karottenkeimlinge reagieren auf den Einstich des Blattflohs mit Blattkräuselung und/oder Blattrollen und es tritt bei Pflanzen mit weniger als vier Blättern ein Wachstumsstillstand ein. So geschädigte Pflanzen erholen sich nicht mehr und bilden keine vermarktbaren Wurzeln aus. Ein bis drei Blattflöhe können so in einigen wenigen Minuten das Wachstum einer Karottenpflanze zum Stillstand bringen.

Autores: Sigsgaard, Lene; Jacobsen, Stíne K.
Fruit growers suffer great economic losses each year due to pest damage. The demand for organic produce is increasing along with the interest from growers to develop sustainable and more resilient production systems and over 20% of the apple production in Denmark is now organic. Available pest management options are limited and prevention is important for resilience. In the project PROTECFRUIT we test the use of functional agrobiodiversity, by promoting the abundance and diversity of natural enemies in ecological infrastructures using perennial, wild flower strips in organic orchards. Rosy apple aphid, Dysaphis plantaginea, infestation and damage, and predator abundance and diversity were assessed in organic orchards with flower strips and compared to...

Provedor de dados: 21
Autores: Weibel, Franco P.; Chevillat, Véronique S.; Rois, Elena; Tschabold, Jean-Luc; Stadler, Walter.
The aim of our study was to find new thinning methods for organic apple production able to fulfil the standards of Bio Suisse, the main label organisation of the organic food sector in Switzerland.   The 17 trials reported were carried out during flowering period in the years 2003, 2004 and 2005 on the cultivars ‘Pinova’, ‘Gala’, ‘Maigold’, ‘Elstar’, ‘Breaburn’, ‘Golden Delicious’ and ‘Otava’ at different sites. The results confirm the good efficiency of mechanical thinning with the rope thinner and the thinning potential of vinasse, a by product of molasses. Different vinasse products were tested (K-Vinasse, light-vinasse, N Vinasse; NK-Vinasse) and it was observed that those containing less nitrogen had a minor thinning effect. To avoid phytotoxicity on...

Formation of canker lesions on stems and black scurf on tubers in experimentally inoculated potato plants by isolates of AG2-1, AG3 and AG5 of Rhizoctonia solani: a pilot study and literature review
Provedor de dados: 21
Autores: Lehtonen, Mari J.; Wilson, Paula S.; Ahvenniemi, Paavo; Valkonen, Jari P.T.
Development of black scurf on potato tubers (cv. Nicola) was compared in plants inoculated with isolates of Rhizoctonia solani of three anastomosis groups (AG2-1, AG3 and AG5) which occur in potato crops in Finland. All isolates induced stem canker lesions but only isolates of AG3 formed efficiently black scurf on progeny tubers. Among the AG2-1 and AG5 isolates tested, only one AG2-1 isolate formed a few sclerotia on 13.5 % of the progeny tubers in one experiment. The data indicate that isolates of AG3 differ from those of AG2-1 and AG5 in having a higher ability to form sclerotia on tubers. Therefore, while AG2-1 and AG5 isolates have a broader host range, AG3 is more efficient in producing black scurf, which provides this anastomosis group with more...

Konzept zur Reduktion der Regenfleckenkrankheit - Ermittlung von Parametern zur Biologie der Erreger unter westeuropäischen Klimabedingungen als Grundlage für die Weiterentwicklung eines Prognosemodells
Provedor de dados: 21
Die Regenflecken- und Fliegenschmutzkrankheit (RFK) breitet sich derzeit im ökologischen Obstanbau stark aus. Befallsgrade von 20 % in trocknen Sommern und bis zu 100 % bei „normaler“ Witterung verursachen empfindliche Einbußen bei der äußeren Fruchtqualität. Befallene Äpfel lassen sich unter den geltenden Qualitätsnormen nicht mehr vermarkten. Moderne Putztechnik zur Entfernung der oberflächlich angesiedelten Symptome (keine Penetration durch die Kutikula) schafft hier nur eingeschränkt Abhilfe. Daher sind selbst bei schorfresistenten Apfelsorten intensive Sommerspritzfolgen (Kupfer und Schwefelkalk) als einzig wirksame Gegenmaßnahme im ökologischen Obstbau erforderlich. Folge sind eine deutliche Verschlechterung der Ökobilanz und damit ein abnehmendes...

Autores: Thürig, Barbara; Binder, Andres; Boller, Thomas; Guyer, Urs; Jiménez, Sonia; Rentsch, Christina; Tamm, Lucius.
We have examined the effect of Pen, an aqueous extract of the dry mycelium of Penicillium chrysogenum, on plant–pathogen interactions. Pen controlled a broad range of pathogens on several crop plants under greenhouse and ﬁeld conditions. Pen protected grapevine from downy and powdery mildew (caused by Plasmopara viticola and Uncinula necator), tomato from early blight (caused by Phytophthora infestans), onion from downy mildew (Peronospora destructor) and apple trees from apple scab (caused by Venturia inaequalis) to a similar extent as fungicides such as copper and sulphur or well-known inducers such as benzothiadiazole or b-aminobutyric acid. Pen had no major direct fungicidal eﬀect and is thus supposed to protect plants by activating their defense...

Rosaceae longhorned beetle, Osphranteria coerulescens, is an important pest of fruit trees that attacks all fruit trees belonging to the family Rosaceae in cold regions of Iran. The potential efficacy of two species of entomopathogenic nematodes (EPN), Heterorhabditis bacteriophora and Steinernema carpocapsae, against last instar larvae of this pest was tested under Laboratory conditions. In plate assays, the larvae were susceptible to both EPN species but were more susceptible to S. carpocapsae (65.0-97.5% mortality) than H. bacteriophora (42.5-87.8%). Both nematode species were able to penetrate and reproduce within O. coerulescens larvae, but reproduction rate for H. bacteriophora was higher than those of S. carpocapsae; however, the penetration rate...

In 2002 and 2003 field experiments with organically grown carrots (cv. 'Rodelika') were performed to investigate effects of ridge vs. flat cultivation, nitrogen supply, EM application and biodynamic spray preparations on yield and sugar fractions. Particularly in the dry summer of 2003 ridge cultivated carrots produced lower yields than those from the flat system. In both years EMs resulted in higher yields; nitrogen fertilization (horn pellets) affected yields only in the first year. Biodynamic horn manure preparation decreased yields and increased glucose content of the carrots in 2003. In 2002 horn silica increased quantities of monosaccharides.

Olive (Olea europaea) is host of 13 different viruses but, it is possible that other viruses, which are either non mechanically transmissible or occur in low concentration in plant tissues, are present in nature. This likelihood is supported by the widespread occurrence of double-stranded RNAs (dsRNAs) in plants negative to biological tests. As very little information is available on the geographical distribution of olive-infecting, investigations were conducted for gathering information on the prevalence and distribution of olive viruses in the Mediterranean basin based on the presence of double stranded RNA (dsRNA). A total of 527 samples were collected throughout the surveys covering 10 countries and 83 locations. Out of 286 tested samples collected...

Prevention of vole damage in organic pomiculture
Provedor de dados: 21
Autores: Walther, B.; Pelz, H.-J.
Vole damage is one of the most difficult phytosanitary problems to solve in organic  pomiculture. A survey conducted in 2002 among German fruit growers showed that 90  % of the farms suffered from this damage. The water vole (A. terrestris) revealed to be  the main pest in 80 % of the orchards. 61 % of the farmers announced a high interest in  the development of new preventive and control methods. To stop immigration of voles  into orchards a mechanical barrier system was developed and tested at two study sites  in Baden-Wuerttemberg and Rhineland-Palatinate. At each location barrier systems with  wire mesh (mesh size 10 mm) and polyolefine-foil were installed arround two 0.7 ha  study plots. Two unprotected plots were used as a control. The barriers were...

Neues Konzept für die ökologische Tomatenzüchtung
Provedor de dados: 21
Trotz steigender Nachfrage stagniert in Deutschland der ökologische Anbau von Tomaten. Ein zunehmendes Problem im geschützten Anbau ist die Samtfleckenkrankheit, verursacht durch den Pilz Passalora fulva (syn. Cladosporium fulvum). Der saisonale, kostengünstige Anbau unter Folie ist dabei besonders betroffen. Die als resistent ausgewiesenen Sorten geben in den traditionellen Anbaugebieten wie am Bodensee mit einer jährlich hohen Befallsgefahr keinen ausreichenden Schutz mehr. Ziel des Projektes ist es, ökologisch angepasste Sorten mit stabiler Resistenz und einem guten Geschmack zu entwickeln. Zum einen soll eine neue, auf das System angepasste Züchtungsstrategie (F4 Kreuzungsnachkommen) erprobt (1) und zum anderen durch reine Kreuzungszüchtung neue...

Provedor de dados: 21
Autores: DANO, Stefan.
Lobesia botrana is the key pest of grape in Albania. On 2005 we started a study which aims at knowing the status of pest and evaluating its management with two varieties of Bacillus thuringiensis, kurstaki &amp; aizawai in several grape cultivars in four farms in 3 different climatic areas. Pheromone Traptest traps were used to monitor the male flight for the best moment of intervention and 400 clusters per ha were sampled to estimate the infestation. Four complete generations appear in all the farms. In three of them, infestation level was under the economic threshold, so treatment were not justified. Bt shows a very good efficacy (75 – 100%), whereas not significant differences are observed between two varieties. The cultivars Black magic, Cabernet...

Autores: Schjønning, P.
Økologisk jordbrug i Danmark har fokuseret meget lidt på jordbearbejdning og færdsel i marken. De traktorer og bearbejdningsmetoder, som en landmand har anvendt i det konventionelle landbrug, vil i langt de fleste tilfælde blive overført til det økologiske dyrkningssystem. Ved økologisk dyrkning skal jordens frugtbarhed fremmes mest muligt ved jordbearbejdningen. Pionerer indenfor den økologiske bevægelse hævder, at et system med minimal og helst ikke-vendende jordbearbejdning (altså uden pløjning) er at foretrække.  De seneste årtiers brug af stedse større traktorer og vogne i landbruget har forårsaget en pakning af jorden under pløjedybde. Pakningen skyldes dels kørsel med tunge traktorer og vogne; og dels hjulets påvirkning i furen ved pløjning (en...

Dans le cadre du CASDAR AGATH, le GRAB a étudié l’impact des bandes fleuries sur les pucerons du melon, Une bande fleurie a été semée en bordure de melonnière, avant la plantation du melon, avec des espèces convenablement choisies (bleuet, gesse, sainfoin, marjolaine, pimprenelle, ammi, aneth, souci, matricaire). En 2015, l’attaque de pucerons a été faible, les résultats doivent donc être pris avec précaution. L’essai réalisé cette année a globalement permis de confirmer les tendances observées en 2013 et 2014 : la bande fleurie héberge plus d’auxiliaires, plus d’auxiliaires spécifiques des pucerons (notamment Coccinellidae et Névroptères) que le sol nu.

In many crops, the intensive use of pesticides causes major problems both for the environment and for natural ecosystem services. Apple is Europe's most frequently produced orchard fruit, requiring high pesticide input to combat the most important apple insect pests, Dysaphis plantaginea (Passerini) and Cydia pomonella (L.). Here we sought to control these pests by promoting natural enemies using sown perennial flower strips. We trialled these in the alleyways of organic apple orchards in seven European countries. Visual assessments over two years revealed a higher number of natural enemies on plant parts, and specifically in D. plantaginea colonies on trees, in flower strip plots than on trees in control plots with standard orchard vegetation. Trees in...

Autores: Daniel, Claudia; Baroffio, Catherine.
La drosophile du cerisier Drosophila suzukii a été introduite en Europe en 2008 et a déjà causé de gros dégâts dans le bassin méditerranéen. Ce nouveau ravageur a été identifié en Suisse pour la première fois au cours de l’été passé. Cette drosophile s’attaque à tous les fruits à chair tendre (baies, cerises, raisins) et à de nombreux fruits sauvages. Cette année, toutes les cultures sensibles doivent être surveillées avec des pièges au vinaigre de pomme. Pour la prévention des attaques, il est recommandé d’utiliser des filets à mailles fines, de faire des piégeages de masse et de détruire les fruits attaqués. L’OFAG a autorisé sous conditions l’utilisation de Spinosad et de pyrèthre.

Suitability of various copper-free leaf treatment products for the control of Phytophthora infestans in organic potato farming
Provedor de dados: 21
Autores: Nechwatal, Jan; Zellner, Michael.
Potato late blight (Phytophthora infestans) causes severe losses in potato yield and quality in organic production. Still, the disease can only be effectively controlled by the application of copper fungicides. Due to copper accumulation in the soil and expected detrimental effects on the environment and non-target organisms, a reduction in the usage of Cu fungicides is urgently required. Within the course of a project aiming at the reduction and avoidance of Cu in organic farming, trials were performed to investigate the efficacy of different Cu-free products for the control of P. infestans leaf infections, and to identify potential alternatives replacing or amending copper based fungicides in the future. We have tested several commercial and...

Pest Management in Organic Field vegetables in Temperate Areas
Provedor de dados: 21
Autores: Daniel, Claudia; Collier, Rosemary; Niggli, Urs; Koller, Martin.
Preventative measures and the creation of resilient growing systems are key parts of pest management practice in organic field vegetable production (see also chapter 1). Soil improvement, crop rotation, site selection, habitat management, variety choice, timing of planting and plant spacing are all considered before planting in order to avoid the most detrimental pest problems. Due to the huge variety of vegetable crops and their associated pest insects, specific tailored approaches are necessary. The effects of cultural practices to reduce pest outbreaks, such as weed control, appropriate irrigation, suitable fertilization, the use of mulches, and adjusted harvest times have been investigated during the last few years. For some crops (e.g. cabbage and...

Qualitative and quantitative evaluation of glucosinolates in cruciferous plants  during their life cycles
Provedor de dados: 21
Autores: Bellostas, Natalia; Sørensen, Jens Christian; Sørensen, Hilmer.
Glucosinolates produced by Brassica species were investigated in relation to biofumigation, a term used to describe the effects some allelochemicals, including glucosinolate derived products, may have on soil-borne pathogens or other herbivores. Four Brassica species of the U-triangle, namely B. nigra (L.) Koch, B. carinata Braun, B. juncea (L.) Czern. and B. rapa L. were compared with respect to their qualitative and quantitative glucosinolate profiles in roots, stems, leaves and reproductive organs. Plants were monitored at four different development stages and the total glucosinolate content as well as their dry matter production as an indication of their potential biomass under field conditions were determined. Glucosinolate levels of up to 120 ìmol g...

Downy mildew caused by the oomycete Plasmopara viticola is the most devastating pathogen of grapevine. In this study, extracts of the bark of eight important northern forestry species were screened to find extracts showing activity against this pathogen and to identify the active compounds. Extracts from all eight species showed activity against P. viticola, the most promising, dichloromethane extracts of three Larix species, almost completely protecting grapevine from downy mildew under semi-controlled conditions. Five promising lead compounds were isolated: larixol, larixyl acetate, lariciresinol and lariciresinol acetate from Larix species and 7a,15-dihydroxydehydroabietic acid from Pinus sylvestris. These compounds showed 90%e100% efficacy. Larixol and...

Effect of Soil Separation Technique with Integrated Catch Crops and Manure on Yield and Quality of Potatoes in Organic Farming
Provedor de dados: 21
Autores: Böhm, Herwart.
The quality of potatoes in stony soils can be improved by the soil separation technique. If this technique is used in autumn in combination with integrated catch-crop growing and fertilization of stable manure or slurry a higher yield was observed, but also a lower leaching rate of nitrate over the winter period. This was tested in field trials under organic farming conditions in 1999 and 2000 on the experimental farm Lindhof of the University of Kiel. Catch crops as oil radish or yellow mustard were able to fix 60 - 70 kg Nt ha-1. Tuber yield after oil radish (36.4 t ha-1) was higher than after yellow mustard (33.0 t ha-1) and was significantly higher compared to the control (30.3 t ha-1). Cowshed manure (80 kg Nt ha-1) or slurry (40 kg Nt ha-1) increased...

Züchterische Verbesserung der sensorischen Qualität der  Pastinake (Pastinaca sativa L.) im Praxisbetrieb
Provedor de dados: 21
Autores: Horneburg, Bernd; Bauer, Dieter; Bufler, Gebhard.
Parsnip (Pastinaca sativa L.) is one of the few cultivated plants domesticated in  Europe. The crop is underutilised and the number of available varieties is small in  Central Europe. On-farm management of genetic resources can be an important  means to increase infraspecific diversity, and to improve the quality of crops. In the  present experiment quality-improvement by progeny selection on-farm was  investigated. In a first step parsnips were selected for organoleptic quality by a  technique that allows to harvest seeds from the plant tested. In a second step,  progenies of positive- and negative-selected plants were compared with the original  population. The experiment was carried out with the varieties Aromata (2006) and  White King (2008) in...

Natural biofertilizers for organic agriculture: productivity and nutrient uptake of Medicago sativa inoculated with different arbuscular mycorrhizal fungi
Provedor de dados: 21
Autores: Avio, Dr. Luciano; Pellegrino, Dr. Elisa; Bonari, Prof. Enrico; Giovannetti, Prof. Manuela.
Arbuscular mycorrhizas are symbiotic associations that play a key role in plant nutrition by absorbing and translocating mineral nutrients from soil to host plants. Arbuscular mycorrhizal fungi, which are considered natural biofertilizers, show diverse levels of performance, depending on the ability of different isolates to promote plant growth and health. Here we investigated the performance of geographically different isolates of two fungal species, Glomus mosseae and G. intraradices, by assessing plant growth responses and P and N uptake in Medicago sativa, in order to select the most efficient fungi for this host plant. The four selected Glomus isolates significantly increased shoot dry weights and shoot N and P content of mycorrhizal plants, but their...

More years of field trials against Plamopara viticola in organic viticulture
Provedor de dados: 21
Autores: La Torre, Anna; Spera, Guido; Gianferro, Marika; Scaglione, Massimo.
The organic viticulture assumes a decisive role in the national agricultural sector.   More impelling problems in the management of organic vineyards are represented by the plants pathology defence and particularly by Plasmopara viticola containment.  Copper represents one of the few usable fungicides in the organic farming and the only one effective against downy mildew. The EC Regulation n. 473/2002 fixed the maximum usable quantity of copper compounds, owing to the environment problems due to the copper accumulation in the soil.  To reduce quantity of metal copper or replace it with natural products, field trials with copper compounds at a low rate  or with alternative copper products have been conducted in organic farms located near Rome. Besides, we...

The distance between forests and crops affects the abundance of Drosophila suzukii during fruit ripening, but not during harves
Provedor de dados: 21
Autores: Cahenzli, Fabian; Bühlmann, Irene; Daniel, Claudia; Fahrentrapp, Johannes.
Drosophila suzukii (Matsumura; Diptera: Drosophilidae) is an invasive pest with the ability to reproduce not only in various soft fruit crops, but also in numerous wild hosts. Forests and forest edges harbor many wild hosts, provide suitable microclimatic conditions and are therefore thought to enhance the abundance of D. suzukii. Although the comprehension of pest activity based on specific landscape elements is important to implement efficient management strategies, knowledge of how forests affect the abundance of D. suzukii in nearby crops is very limited. We conducted a monitoring study with liquid baited traps across different crops at different distance from the forests. During fruit ripening, more flies were captured in crops closer to forests...

Contamination of grain with Mycotoxins by Fusarium spp, Aspergillus spp. and Peni¬cillium spp. is a serious problem in conventional and organic cereal production. Based on a literature survey of in total 183 German and international papers (original articles, review articles, conference abstracts and contributions to textbooks) the following agronomical factors were judged to be of major importance for a possible contamina¬tion of cereals with mycotoxins: growing conditions, choice of variety, pre crop, soil tillage intensity, use of fungicides, weed control, intensity of fertilisation and storing conditions. Due to the fact that conventional compared to organic farming in general shows narrower crop rotations with a higher number of risky pre crops as...

Demand for organic foods, especially vegetables has increased tremendously due to reasons such as safety, environmental concerns, flavour and freshness, health benefits and nutritional value. In the current agricultural production environment, conventional farming methods pose the greatest risks in terms of reduced crop yields due to soil degradation. In the face of climate change and variability (CCV), field experiments are limited and without appropriate modelling techniques future crop production scenarios can’t be predicted leading to food insecurity. A survey and field experiment were done to assess crop productivity under organic based cropping systems and impact of CCV on soil nutrients and maize yields during the short and long rains seasons of...

Les escargots et les limaces peuvent causer des dégâts considérables en grandes cultures ou en maraîchage. En Agriculture Biologique, leur maîtrise est d’autant plus importante que les traitements spécifiques sont limités au métaldéhyde qui sera probablement interdit en 2007. La principale alternative est l'orthophosphate de fer, récemment homologué. Ce produit fait l'objet d'essais au Groupe de Recherche en Agriculture Biologique. Ceux-ci démontrent que son efficacité, équivalente au métaldéhyde appliqué en piège en conditions sèches, est moindre sur des escargots de taille adulte et en cas de lessivage.

Effect of ascorbic acid and glutathione on the production of nitriles by myrosinase
Provedor de dados: 21
Autores: Bellostas, Natalia; Sorensen, Jens Christian; Sorensen, Hilmer.
Biofumigation is based on the use of glucosinolate-containing plants for the control of soil-borne pest and diseases. Upon tissue damage, glucosinolates are hydrolyzed by endogenous enzymes (myrosinase) and a range of biologically active compounds are formed. Isothiocyanates (ITCs) are the quantitatively dominating products formed at neutral pH. Most of these compounds are volatile and only sparingly soluble in aqueous systems, and depending on the R-group structure and the presence of nucleophiles, further transformation of ITCs occurs. At lower pH and in the presence of certain molecules able to deliver two redox equivalents, the proportion of nitriles increases at the expense of ITC.   The effect of ascorbic acid and glutathione on the production of...

Reduzierung oder Ersatz kupferhaltiger Pflanzenschutzmittel im ökologischen Hopfenbau
Provedor de dados: 21
Namhafte Abnehmer von Ökohopfen fordern von den Produzenten einerseits optimale Qualität bei den Hopfendolden, andererseits den Verzicht auf Kupfer. Einzelne Brauereien fordern in geringem Umfang auch noch Hopfen von anfälligen Sorten.  Zur Bekämpfung der Krankheit 'Falscher Mehltau', verursacht durch den Pilz Pseudoperonospora humuli, sind kupferhaltige Produkte bisher unverzichtbarer Be-standteil der Wirkstoffe. Die derzeit von den Ökoverbänden zugelassene Auf-wandmenge im Hopfen beträgt 4,0 kg Reinkupfer pro Hektar und Jahr. Ergänzt durch weitere biologische Produkte wie Gesteinsmehl kann damit die Krankheit wirkungsvoll bekämpft werden.  Da Kupfer ökotoxikologisch kritisch beurteilt wird, besteht die Forderung, auf Kupfer ganz zu verzichten bzw. auf...

Robustness in the mineral supply from temporary grasslands
Provedor de dados: 21
Autores: Høgh-Jensen, Henning; Søegaard, K.
The current study examined the capacity of different temporary grassland legume-grass mixtures under different N supply levels to supply similar amounts of elements in systems where the herbage is cut and feed. Mixtures showed a good robustness in supplying equal amounts of mineral elements in the combined herbage as well as equal concentrations in dry matter of mineral elements compared to the same species in monocultures. The reasons for the mixed systems to be able to buffer differences in N supply levels as well as different compositions of the mixtures were that legume leaves and stems had similar concentrations of mineral elements, whether in monocultures or in mixtures with grasses. Grasses in mixture with legumes had however higher N, Ca, S, Zn, Cu...

Testing of the apple varieties ‘Topaz’ and ‘Rubinola’ on different rootstocks
Provedor de dados: 21
Autores: Ruess, Franz.
‘Topaz’ was the mostly planted apple variety with scab resistance in the recent years. It took only a  few years for this variety to get that importance in organic orchards. New apple varieties always  should be tested on different rootstocks, because there is an individual relationship between varieties  and rootstocks. The apple varieties ‘Topaz’, ‘Rubinola’ and ‘Rosana’ were tested on the rootstocks  ‘M 26’,‘M 9’, ‘JOHA’, ‘P 22’ and ‘M 27’. ‘Topaz’ showed the best results concerning yield and  fruit size on ‘M 9’. ‘Rubinola’ which is a strongly growing variety was better on the rootstock ‘JOHA’.  The decision which rootstock is the best also depends on soil and water conditions.

Disease control by sulphur induced resistance
Provedor de dados: 21
Autores: Haneklaus, S; Bloem, E; Schnug, E.
As early as the 19th century, Justus von Liebig (1803 – 1873) identified the lack of vitality of soils and non-existent vigour of plants as relevant causes of increased infections of crops by fungal diseases. Organic farming requires alternative strategies for combating pests and diseases. Soil-applied sulphate fertilisation proved to significantly reduce infection rate and severity of crops by fungal diseases. The potential efficacy of socalled Sulphur Induced Resistance (SIR) expressed as a reduction of the disease index ranged from 5–50% and 17–35% in greenhouse and field experiments, respectively. Metabolic pathways involved in SIR imply, for instance, the synthesis of phytoalexins, glutathione, glucosinolates and the release of sulphur-containing...

Effects of burying and removing dead leaves from the ground on the development of scab epidemics in an apple organic orchard.
Provedor de dados: 21
Autores: Gomez, C.; Brun, L.; Chauffour, D.; de Le Vallée, D.; Rolland, E.
Ascospores produced on scabbed leaves in the leaf litter constitute the primary  inoculum causing scab infections in apple orchards during the year. The trial, carried  out in a commercial organic orchard, permitted to evaluate the effects of the  removal of dead leaves located on the inter-row supplemented by the ploughing in of  the leaves left on the row, on the development of scab epidemics. From the first  recorded contamination to harvest time, lesions on leaves and fruits were counted to  determine reduction in disease incidence and severity, compared with the untreated  plots. Disease severity as a function of the distance from the untreated plot was also  observed, to evaluate the spore dispersal gradient within the orchard. The results  show that...

Association d’une culture de blé avec un couvert de légumineuses en agriculture biologique: Mise en évidence de l’effet du couvert sur la dynamique des bio-agresseurs et des adventices du blé
Provedor de dados: 21
Autores: Pesset, Rémi.
L’agriculture biologique interdit d’utiliser des intrants chimiques pour contrôler les fléaux des cultures que sont les maladies, les ravageurs et les adventices. En systèmes céréaliers biologiques, les traitements d’origine naturelle se montrent souvent peu efficaces et les pertes de rendement parfois importantes. L’implantation de légumineuses sous couvert, en plus d’améliorer naturellement la fertilité azotée du sol pour la culture suivante, peut limiter le développement des adventices naturellement. Par cette pratique, les caractéristiques du milieu sont modifiées, ce qui peut aussi influencer la dynamique des bioagresseurs du blé. Cet effet est en revanche plus difficile à anticiper et l’impact de telles associations sur les bioagresseurs de la...

Neue Anbaustrategien bei Zwiebeln als vorbeugende Maßnahme zur Vermeidung von Krankheiten (Falscher Mehltau, Fusarien) im Zwiebelanbau
Provedor de dados: 21
Autores: Fuchs, Alexander; von Mansberg, Arved; Rascher, Birgit.
Der ökologische Zwiebelanbau wird in Süddeutschland aktuell in Form von zwei Anbauverfahren praktiziert. Auf Standorten mit geringem Infektionsdruck durch Falschen Mehltau und einer ausreichenden Wasserversorgung herrscht der Säzwiebelanbau vor. Die Wirtschaftlichkeit des Anbaus wird bei diesem Verfahren durch den Falschen Mehltau und die hohen Kosten für die Unkrautregulierung begrenzt. Der Anbau von Steckzwiebeln wird vor allem auf Standorten mit höherem Infektionsdruck durch Falschen Mehltau und unsicherer Wasserversorgung praktiziert. In den letzten drei Jahren waren bei diesem Anbauverfahren aufgrund von Fusariosen auf einem Großteil der bayrischen Anbauflächen Ertragsausfälle von bis zu 50% und schlechte Qualitäten zu beklagen.

Evaluation and registration of plant protection inputs for organic farming
Provedor de dados: 21
Autores: Speiser, B.; Tamm, L.; Schmid, O.
Organic farmers may only use those plant protection products which are listed in Annex II B of the ‘Organic Regulation’ 2092/91 and also registered for use at national level. At present, new compounds may only be listed in Reg. 2092/91, if they do not come into direct contact with the crop (although in perennial crops, contact outside the growing season of the edible parts is possible), which is a major obstacle for progress. The EU-funded ORGANIC INPUTS EVALUATION project aims at making Reg. 2092/91 more flexible with regard to new products, while safeguarding the principles of organic farming. Registra-tion under the ‘Pesticide Directive’ 91/414 represents a considerable financial hurdle. The REBECA project will propose registration requirements which...

Effects of intercropping and fertilization on weed abundance, diversity and resistance to invasion
Provedor de dados: 21
Autores: Sans, F. X.; Altieri, M. A.
This paper aims to evaluate the effects of the cover crop type (Vicia villosa monoculture vs. V. villosa and Hodeum vulgare polyculture) and the type of fertilization (organic vs. chemical) on the structure of the weed community (biomass, number of species, diversity and evenness) and its invasibility through the experimental introduction of Brassica sp. seeds as a target invader species. Results show that weed biomass, species richness and diversity of the weed community are significantly reduced by inter-cropping, but are not affected by the type of fertilization. In organic plots, the density increases and the complementary pattern of polyculture resource use reduces weed abundance and Brassica sp. invasion, while the rapid emergence and fast growth of...

Användning av kompost för att kontrollera den jordburna sjukdomen korkrot i ekologisk tomatodling
Provedor de dados: 21
Inom den svenska ekologiska växthusodlingen är tomat den enskilt största kulturen. Den jordburna sjukdomen korkrot, orsakad av svampen Pyrenochaeta lycopersici, utgör det allvarligaste odlingsproblemet. I intensiva produktionssystem eller när samma jord används 3-4 år kan skördereduktionen uppgå till 30-40%. Tidigare forskning har visat att tillförsel av kompost i vissa fall kan hämma växtpatogener och minska sjukdomsangrepp. Tanken med detta projekt är att undersöka möjligheten att hämma korkrot genom att tillföra olika slags komposter, möjliga att framställa utifrån lokala resurser på ekologiska gårdar.          Vi ska studera komposter gjorda av grönmassa (rödklöver), gödsel respektive trädgårdsavfall och initialt pröva den hämmande förmågan i 10...

Autores: Fuchs, Jacques G.; Mayer, Jochen; Berner, Alfred.
One hundred Swiss composts and digestates were investigated in order to evaluate  their influence on plant growth and health. Important differences in biological compost  quality and on the impact on soil fertility and on plant health were observed. The most  important limiting factor of compost quality is the possible immobilization of  mineralized nitrogen by some composts. However, quality composts have a good  potential to protect plants against diseases. More attention should be paid to the  control of the composting process in order to improve the biological quality of  composts with more beneficial effects on crops.

Developing new management options for soil-borne pests of organic systems
Provedor de dados: 21
Organic arable systems generally depend upon grass/clover leys in rotations to build nutrients. This increases exposure to subterranean insect pests such as leatherjackets and wireworms. Current control methods for theses pests rely on insecticide application -an option not open to organic producers. This project will build upon existing knowledge and make a detailed study of those aspects of the pests' ecologies that impinge upon the problem. The rotational and environmental factors resulting in field/crop combinations being vulnerable will be identified so that growers can predict when there is a high risk. Within field environmental variation will be linked to the spatial distribution of the pests and recommendations for sampling vulnerable areas will...

Provedor de dados: 21
Autores: Zimmer, Jürgen; Benduhn, Bastian; Mayr, Ulrich; Kunz, Stefan; Rank, Harald.
Als Zwischenfazit aus dem ersten Versuchsjahr konnte festgestellt werden, dass gezielte Behandlungen in die Infektion mit Netzschwefel oder Kupferpräparaten einen besseren Wirkungsgrad erzielten, als der protektive Einsatz dieser Mittel. Die Berostungsgefahr bei dem Einsatz von Kupfer zur Zeit der Feuchtephase reduzierte sich, jedoch wurden im Vergleich zum protektiven Einsatz von Kupfer auch weniger gezielte Behandlungen durchgeführt.  Alternativprodukte wie z.B. VitiSan und Armicarb, welche zu den Kaliumbicarbonaten zählen, wurden zum Zeitpunkt der Infektion und kurativ 24 Stunden nach der Infektion solo und in Mischung mit Netzschwefel appliziert. Hierbei zeigte sich im ersten Versuchsjahr, dass diese Produkte zu diesem Zeitpunkt eine interessante...

Potential of different Composts to improve Soil Fertility and Plant Health
Provedor de dados: 21
Autores: Fuchs, J.G.; Baier, U.; Berner, A.; Mayer, J.; Tamm, L.; Schleiss, K.
Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. Some practitioners already make use of the positive effects on plant health. For example, they use composts to protect their plants against soil borne diseases in substrate, or to detoxify and reactivate soil after steaming. In order to estimate the potential of Swiss composts to influence soil fertility and plant health positively, we analyzed one hundred composts representative of the different composting systems and qualities available on the market.

Regulierung Falscher Mehltau Pilze an Gemüsekulturen im ökologischen Landbau am Beispiel von Salat und Zwiebeln
Provedor de dados: 21
Autores: Kofoet, Andreas; Fischer, Kirsa.
Im ökologischen Gemüsebau ist der Falsche Mehltau ein bedeutendes Problem und führt in vielen Kulturarten zu hohen Ertragsverlusten. Zur Zeit sind weder genügend wirksame Resistenzen bekannt, noch geeignete Anbautechniken vorhanden, die einen ausreichenden Schutz gegen Mehltaupilze bieten würden. Der Einsatz von Pflanzenstärkungsmitteln mit einer effektiven Wirkung gegen Falschen Mehltau wäre eine mögliche Lösung des Problems. Allerdings gibt es bisher kaum Untersuchungen, in denen die Wirksamkeit der Stärkungsmittel unter standardisierten Bedingungen geprüft wurde. Die Erfahrungen aus der Praxis sind sehr unterschiedlich und die Wirksamkeit muß vom Hersteller nicht nachgewiesen werden. Wenig bekannt ist auch, daß bei einigen Kulturarten eine primäre...

Provedor de dados: 21
Autores: Jaastad, Gunnhild; Knudsen, Geir K.; Kobro, Sverre; Bäckman, Anna-Carin; Witzgall, Peter; Bengtsson, Marie.
Apple fruit moth, Argyresthia conjugella Zell. (Lepidoptera: Argyresthiidae), is the most important  pest of apples in Scandinavia. In years when its primary host, rowan (Sorbus aucuparia L.), has little  or no berries for egglaying, female A. conjugella fly into apple orchards to lay their eggs. In some  years the entire apple crop can be destroyed. Volatiles from apples and rowan have been collected  and identified. In GC-EAD tests females have responded to several compounds found in both  rowan and apple. Some of these compounds were used in field trapping tests during 2002, and a  mixture of two compounds trapped significantly more females and males compared to control traps.  However, field trapping results from 2003 indicate that the two-compound...

An ancient compound rediscovered: perspectives of aphid control in organic hop growing by the use of quassia products
Provedor de dados: 21
Autores: Weihrauch, Florian; Eckert, Markus; Engelhard, Bernhard.
In the first three decades of the 20th century, quassia extract was widely used in hop growing as a chemical agent to control Phorodon humuli and other insect pests. In the first years of the 21st century this compound was rediscovered by German organic hop growers. In nine efficacy trials conducted in five field seasons, quassia products proved to be effective control agents for P. humuli in organically grown aroma cultivars. As the best method of application a systemic variant was developed by painting a suspension of quassia extract to the bines. This method proved not only to be very effective but was also best from an environmental point of view as sprayed quassia extracts had side effects on non-target organisms. As an optimal systemic application...

Results from an experiment about pruning of the apple variety ‘GoldRush’
Provedor de dados: 21
Autores: Pfeiffer, Barbara.
The scab resistant  apple variety ‘GoldRush’ can be grown in regions, where vineyards are common. At the LVWO Weinsberg ‘GoldRush’ is ripening about October 20th. In organic fruit growing this variety must be thinned strongly, because it tends to alternate bearing. The intention of the small experiment in the organi-cally grown orchard Katzental was to reduce by special pruning measurements the time for thinning by hand and to improve the fruit quality. During the years 2001 to 2005 clear effects could be seen on the size of the apples. The time for hand thinning varied from year tot year depending from the setting of blossom clusters, but there was no success in reducing thinning time by pruning alone. There was a positive influence on the quantity of...

Hestebønner - sortsvalg og etablering
Provedor de dados: 21
Autores: Schou, Anders.
Skal økologer dyrke hestebønner? Det er der delte meninger om, særligt blandt de avlere der har forsøgt sig med afgrøden. Risikoen ved dyrkning er større end ved korn, men hvis håndværket er i orden kan en række af udfordringerne afhjælpes. Tørke, lus og chokoladeplet er desværre ikke noget økologer er herre over, og derfor er hestebønner en afgrøde der i værste fald mislykkes helt, men i de bedste år giver hestebønner mellem 4-5 tons pr. ha. Usikkerheden i udbytte opvejes i nogen grad af de fordele, som dyrkning af hestebønner giver i sædskiftet.

Bio-PhytoPRE - ein Warn- und Prognosesystem zur Bekämpfung der Kraut und Knollenfäule im ökologischen Kartoffelanbau in der Schweiz
Provedor de dados: 21
Autores: Musa-Steenblock, Tomke; Forrer, Hans-Rudolf.
In organic potato production, copper fungicides are the only mean for an effective direct control of late blight. To avoid negative impacts of copper accumulation in the environment, intensive research is done to develop efficient copper free agents (CFA) and new strategies for disease prevention. However, the search for such CFA and strategies proves to be more difficult than expected. Therefore an abdication of copper products is not yet possible. To approach a copper free organic potato production, the Agroscope FAL Reckenholz is developing the Bio-PhytoPRE decision support system to assist Swiss organic potato producers to control late blight with reduced amounts of copper or CFA.

Anfälligkeit von Leguminosen gegenüber Meloidogyne hapla
Provedor de dados: 21
Autores: Reents, Dr. H. J.; Egerer, Johanna; Hermann, A.
Green manure legumes are a necessary element of organic crop rotations. However,  they are able to propagate nematodes especially Meloidogyne and Paratylenchus  species. The results of a pot experiment showed that plant species of the genera  Pisum, Vicia, Trifolium had a higher propagation rate of Meloidogyne hapla than salad  Latuca sativa while plant species of the genera Medicago and Melilotus were less  susceptible to infestation of nematodes. It is concluded that crop rotation management  especially in vegetable production has to consider the different susceptibility of the  legumes and further research has to test more species and varieties.

Autores: Bertelsen, Marianne.
In the spring 2012 narrow plastic covered roofs were erected over 6 x 8 trees in rows of Red Elstar and Rubens apples. Three of the eight trees were sprayed with sulphur and potassium bicarbonate in case of rain, the other 5 remained unsprayed. The roofed treatments were compared to unsprayed trees, and trees sprayed intensively with sulphur and potassium bicarbonate. The aim of the experiment was to investigate if reduced leaf wetness caused by the protection of the roofs could substitute the use of fungicides.

Differences between spring wheat cultivars in susceptibility to Fusarium caused seedling blight
Provedor de dados: 21
Autores: Timmermans, Dr. B.G.H.; Osman, Ir. A.M.
Fusarium spp. present on spring wheat seeds can infect seedlings and cause reduced plant densities and higher wheat infestations. In the current project, variation between commercially available spring wheat cultivars in their tolerance to Fusarium seedling blight was investigated in a pot and a field trail. Additionally, initial growth rates of cultivars were measured to investigate possible relations with tolerance. Preliminary analysis shows presence of  tolerance differences between the spring wheat cultivars in the pot and field experiment. This difference was relatively robust (experiment x cultivar interaction was not significant). Preliminary analysis also showed a relation between tolerance and initial growth rates of cultivars in the field...

Thinning of Organic Apple Production with Potassic Soap and Calcium Polysulfide at the North of Spain.
Provedor de dados: 21
Autores: Dapena de la Fuente, Enrique; Fernández-Ceballos, Alfonso.
Asturias, in the North West coast of Spain, is a region with old tradition at cultivation of  apple and its transformation to cider. The production of apple is mainly done under  traditional uses and semi-extensive or semi-intensive system and with local cultivars.  Thinning strategy is little practiced and the biennial bearing cycle is one of the main  problems for the farmers. The production of apple under organic techniques in Asturias is  still limited but increasing. Since 2005, experiments have been conducted on several  cultivars (‘Raxao’, ‘Xuanina’ and ‘Gold-Rush’) to evaluate the effects of Potassic Soap  (with or without olive oil) and Calcium Polysulfide as thinning products. We present here  the first promising results of these experiments....

Drosophila suzukii control using Kaolin, lime and rock dusts.
Provedor de dados: 21
Autores: Strack, Timo; Cahenzli, Fabian; Daniel, Claudia.
The Spotted wing drosophila, Drosophila suzukii, is an invasive pest in Europe and North America, infesting various soft-skinned fruits. Because D. suzukii attacks ripening fruits shortly before harvest, only insecticides with short pre-harvest intervals can be applied. Alternatively, kaolin, lime and rock dusts are non-toxic to non-target organisms, but the whitish coating on fruits potentially deters oviposition of D. suzukii. Therefore, we tested oviposition deterrence and insecticidal effects of such substances. Female D.suzukii flies were exposed to treated blueberries under laboratory conditions for 24 hours. Kaolin, clinoptilolite, clinoptilolite + Heliosol (pine-oil based wetting agent) and calcium carbonate significantly reduced oviposition,...

Autores: Groot, S.P.C.; Jalink, H.; Köhl, J.; Langerak, C.J.; Michta, A.; Werner, S.; van der Wolf, J.M.; van den Bulk, R.W.
Production of high quality organic vegetable seeds encounters several challenges. Research is performed to support seed companies in producing vigorous and healthy organic vegetable seeds. Examples are provided with respect to research on seed vigour, determining critical control points to avoid disease transmission to the seeds, seed treatments with natu-ral compounds, new seed sorting techniques and enhancement of the natural plant defence. It is noticed that the restrictions in EU regulation 2092/91 on organic production are at present blocking the use of promising natural and sustainable components for seed treatments.

Susceptibility of different grape varieties to Drosophila suzukii oviposition
Provedor de dados: 21
Autores: Cahenzli, Fabian; Daniel, Claudia.
In laboratory no-choice trials, we found significant differences in susceptibility of eleven different grape varieties to oviposition of D. suzukii. However, there was no obvious effect of berry color on oviposition, since varieties with dark berries ranked among the most susceptible varieties (Cabernet Cortis and IRAC 1999), but also provided the three least susceptible varieties (Chambourcin, Prior and Blauburgunder). All varieties with white berries (Solaris, VB 32-7, Seyval Blanc, Johanniter, Prior, Bronner) and one blue variety (VB 91 26 04) ranged in between. Furthermore, sugar content and harvest date had no significant effect on oviposition. We hypothesize that fruit skin firmness affects susceptibility to oviposition of D. suzukii and suggest to...

The Plateau of Santa Catarina state, Brazil, is the main potato seed producer of the country. Its regional climate, however, with wet summers has been pointed out as the main factor for restricting productive quality and raising prices. This research had, thus, the objective of studying the efficacy of homeopathic preparations, homemade formulations and genetic variability in the management of pests and diseases at field conditions on organic farming systems of potato crops. Two field experiments were installed during the 2006/07 crop season. In experiment 1, the following genotypes were planted as treatments: Catucha and Epagri (landrace), Monalisa and Agata (Holland), and Panda (Germany). In experiment 2, the statistical design was a split plot with the...

Field applications of entomopathogenic fungi against Rhagoletis cerasi
Provedor de dados: 21
Autores: Daniel, C.; Wyss, E.
Two myco-insecticides, Naturalis-L (Beauveria bassiana) and PreFeRal®WG  (Paecilomyces fumosoroseus), were applied against adult R. cerasi (Diptera: Tephritidae)  in two orchards in north-western Switzerland in summer 2006. Both products were applied  at a concentration of 5.75x104 CFU / ml. With four applications at seven day intervals the  whole flight period of R. cerasi was fully covered. During this period (5th June – 6th July)  the temperature averaged 19.2°C, total precipitation was 60 mm. Under these conditions  Naturalis-L significantly reduced the number of damaged fruit (efficacy: 69-74%), whereas  damage was not significantly reduced with PreFeRal®WG (efficacy: 27%). Fungus  infested flies were found on the yellow sticky traps proving that the...

Ertrag und Qualität von ökologisch angebauten Zwiebeln in drei Anbausystemen (Direktsaat, Kultur über Steckzwiebeln bzw. Jungpflanzen) unter besonderer Berücksichtigung der Unkrautregulierung
Provedor de dados: 21
Autores: Koller, Martin; Vieweger, Anja; Lüscher, Samuel; Lichtenhahn, Martin.
Zwiebeln werden im ökologischen Gartenbau häufig über Steckzwiebeln angebaut. Der Anbau benötigt eine kürzere Kulturzeit und die Unkrautbekämpfung ist einfacher als im Direktsaatverfahren. Da im Praxisanbau Probleme mit pflanzgutübertragbaren Krankheiten (Peronospora und Fusarium) und der Produktequalität (geringe Schalenfestigkeit) vermehrt auftreten, gewinnen andere Anbauweisen an Bedeutung. Auf einem Öko-Betrieb wurden die drei Anbausysteme Direktsaat, Kultur über Steckzwiebeln und Kultur über vorgezogene Jungpflanzen in einem praxisnahen Streifenversuch über zwei Jahre verglichen. Die drei Verfahren wurden auf Zeitbedarf für das Handjäten, den Ertrag und die Erntequalität hin untersucht.

Organic vineyards still rely on large external inputs to control harmful organisms (i.e., pests). The BIOVINE  project aims to develop natural solutions based on plant diversity to control pests and reduce  pesticide dependence. The capability of plants of increasing the ecosystem resistance to pests and invasive  species is a well-known ecosystem service. However, monocultures (including vineyards) do not  exploit the potential of plant diversity. BIOVINE aims to develop new viticultural systems based on increased  plant diversity within (e.g., cover crops) and/or around (e.g., hedges, vegetation spots, edgings)  vineyards by planting selected plant species for the control of arthropods, soil-borne pests (oomycetes,  fungi, nematodes), and foliar...

Autores: Tilcher, Ralf; Dürger, J.; Jorek, Bettina; Diehm, M.; Neuberger, K.; Esther, A.
Damages of planted seed and emerged seedlings caused by birds represent a significant problem in organic farming since there is no chemical repellent available. Bird attack often leads to reduced emergence and yield decrease. In the course of a perennial cooperation project 30 different plant extracts were systematically checked on the ability to prevent bird damage. Corn seed was applied with different extracts and tested via choice trials (seed and seedling) in aviaries. This screening resulted in detection of repellent effective extracts, whereby combined application of several  extracts increased the positive activity. Accompanying tests showed no negative impacts of the extract application on seed quality (germination, vigour). First field trials...

Assessing varietal resistances to control common wheat bunt under organic cereal production and soft wheat, in particular
Provedor de dados: 21
Autores: FONTAINE, L.; du CHEYRON, P.; MORAND, P.; SKIKERS, S.
Common wheat bunt (caused by the fungus Tilletia caries or Tilletia foetida) is a disease whose incidence is clearly on the rise in organic farming, jeopardising the balance of the French organic cereal sector. Control methods adapted to organic farming must be found, especially since we know that no seed treatment is 100% effective. The use of varietal resistance appears particularly promising for limiting the spread of the disease. Since 2000, an experiment whose purpose is to assess the resistance of soft wheat varieties to Tilletia caries is conducted each year by the French plant institute, ARVALIS. These experiments make it possible to identify the existence of a wide behavioural variability with respect to this pathogen among the different varieties...

Cyclic vole species, particularly the Water vole (Arvicola terrestris), cause substantial agricultural damage throughout their wide geographical range. In organic pomiculture synthetic pesticides are not allowed. Trapping and fumigation remain the only applicable measures for managing voles but require a lot of time and personal skills. The success of using these methods is reduced by the fast recolonisation of the empty areas. To stop the permanent overground immigration of voles a mechanical barrier system was developed and tested in enclosures and at two study sites in Baden-Wuerttemberg and Rhineland-Palatinate between October 2002 and October 2003. The barrier, consisting of a low fence of whire mesh or polyolefin foil, reached 20 cm below and 30 cm...

The effects of climate  change on plant pathogens could be roughly divided in three groups: 1) Direct effects on plant  pathogens environment: on temperature and moisture during the growing season and winter.  2) Effects on host plant: increased CO2 level, autumn sown crops, abiotic stresses. 3) Indirect  effects on plant pathogen: evolution of pathogens to better survive in changed environment.  In this paper, the changes that have been observed in plant pathogen species on field crops in  Finland will be discussed.

Management of pest insects at a farm level is only suitable for farmers owning compact areas of land, which is not the case in many central European areas. This situation favours direct, short-term control of mobile pests and pathogens over preventive, long-term strategies to lower the overall population level. Regional or area-wide control is difficult to establish because it requires considerable collaboration between neighbouring farmers. In addition, research institutions usually lack the appropriate size of farms to prove that these strategies can have a reliable efficacy which would warrant greater efforts by farmers to collaborate on a regional basis....

Einfluss der Bewirtschaftungsform, der Vorfrucht und der Düngung auf den Befall von Winterweizenkörnern mit Pilzkrankheiten im DOK-Versuch
Provedor de dados: 21
Autores: Gunst, Lucie; Krebs, Heinz; Dubois, D.; Forrer, H.-R.
In the DOK long-term field trial in Switzerland comparing bio-dynamic, bio-organic, and conventional farming systems, the occurrence of Fusarium species and Microdochium nivale on grains of wheat was investigated from 1997 to 2003. Although no differences between the farming systems were found, the previous crop, the fertilisation level, and the year significantly influenced the disease incidence. In 2003, the effect of the pre-crops potatoes versus silage-maize on fusaria was compared. As expected, the incidence of fusaria was significantly higher after maize compared with potatoes. However, the main responsible species was not F. graminearum but F. poae. This species is known for the production of hazardous toxins. A greater input of fertiliser resulted...

Kaolin as a possible treatment against lepidopteran larvae and mites in organic fruit production
Provedor de dados: 21
Autores: Jaastad, G.; Røen, D.; Hovland, B.; Opedal, O.
Few control methods are available in Norwegian organic fruit production that can prevent damage by early and late larvae. Also phytophagous mites are difficult to control without harming the beneficial mites. Proc-essed kaolin function by coating trees and thus creating a physical barrier to infestation, impeding move-ment, feeding and egg-laying. Kaolin may reduce feeding and movement of over-wintering tortricide larvae and other larvae that hatch early in spring and have a repellent effect against egg-laying tortricide females in summer. Kaolin may also have a control effect against mites as it clings to the body and reduce feeding. Tri-als with kaolin were conducted in 2003, 2004 and 2005 in plum and apple orchards. Results show that kaolin reduces the...

New approaches in biological control of apple scab
Provedor de dados: 21
Autores: Köhl, J.
Apple scab caused by Venturia inaequalis is a major disease in apple production. In  organic farming scab control depends on the use of fungicides based on copper or  sulphur. Since the use of copper will be restricted in the European Union and the use of  sulphur often leads to insufficient control and phytotoxicity, alternative control measures  are needed. The use of microbial antagonists may be an alternative to fungicides for scab  control.  Scab epidemics during summer are driven by conidia produced only on apple leaves. In  this situation, antagonists present in the phyllosphere may interfere with conidia of the  pathogen during sporulation or infection. Within the EU-funded project REPCO, more than  hundred fungi were isolated from sporulating scab...

Effect of seed treatment with milk powder and mustard flour in control of common bunt (Tilletia tritici) in wheat and stem smut (Urocystis occulta) in rye
Provedor de dados: 21
Autores: Borgen, Anders; Kristensen, Lars.
In field trials mustard flour was able to control seed borne infection by common bunt (Tilletia tritici) in wheat without decreasing the germination vigour of the treated seeds. Full control of common bunt by coating the seeds with milk powder could only be achieved at doses which reduced germination vigour of the seeds. Mustard flour can be recommended as a seed treatment in organic agriculture while a treatment based on milk powder should be developed in combination with biological control. Both milk powder and mustard flour can be used to control stem smut in rye (Urocystis occulta).

AN ALTERNATIVE APPROACH TO PLANT HEALTH: THE PROCEDURAL CONCEPT APPLIED TO COMMON BEAN SEED SYSTEMS
Provedor de dados: 21
Autores: Klaedtke, Stephanie; Stassart, Pierre; Chable, Véronique.
Pathogen-free seed is one strategy to protect plants and prevent the introduction and spread of dangerous pests.   While this strategy reduces damage to crops and delays the global spread of pathogens, it may also be regarded as an overly reductionist approach to plant health disfavoring the resilience of cropping systems. Rather than defining plant health as an objective entity, a procedural concept consisting of a set of rules for debate in order to incorporate different viewpoints on the continua between naturalist and normativist approaches, negative and positive definitions, reductionism and holism and functionality and resilience has been proposed. In the ongoing research project presented here, the questions suggested are applied to the case of...

Interactions between fungal plant pathogens on leaves. Especially simultaneous development of Rhynchosporium secalis and Drechslera teres on barley
Provedor de dados: 21
Autores: Vollmer, Jeanette Hyldal.
Disease causing fungi are a major potential threat to yield in both organic and conventional cereal production, and generally several different species of pathogenic fungi are found together on the same plants in the field. This PhD thesis concludes that interaction between different fungal  species may influence total disease levels and often via negative effects, such that less disease is observed where several diseases occur together relative where they are found individually.   Such potential interaction effects have often been ignored in the past, as plant diseases have traditionally  been studied as single independent events. The thesis provides an important review of  available literature on the subject; which considers the theoretical background...

Provedor de dados: 21
Autores: Schärer, Hansjakob; Mahlberg, Nicole; Tamm, Lucius; Koller, Martin.
To grow carrots in organic quality for storage is often difficult due to seed- and  soilborne diseases. In a series of experiments, seed treatments were evaluated to  improve seed health, field stand establishment and yield of carrots under field  conditions on farmer’s fields within their production system. In standard germination  tests in the laboratory, positive effects of the treatments were observable. However, in  subsequent field experiments, none of the tested seed treatments improved crop  establishment or yield. These results indicate that the quality of organic carrot seeds is  generally sufficient and improvements with farm-made seed treatments are difficult to  obtain. Further improvement in organic production of carrots may be achieved by...

Habitat manipulation – as a pest management tool in vegetable and fruit cropping systems, with the focus on insects and mites
Provedor de dados: 21
Autores: Nilsson, Ulf; Porcel, Mario; Świergiel, Weronika; Wivstad, Maria.
Today, there is increasing interest among Swedish growers in biological diversity within the agricultural landscape. Many scientific studies have highlighted the services performed by beneficial organisms, which can help to improve the quantity and quality of crops. One tremendously important ecosystem service is biological control of pest insects and mites. The question is what growers can actually do to increase the abundance and diversity of natural enemies and whether this will have an impact on the pest population and, more importantly, on yield and quality of the crop. Another question is whether biodiversity is always positive for growers or whether there are negative aspects that should be dealt with. These relevant questions are addressed in the...

Pflanzenschutz in Zuckermelonen: Echter Mehltau und mehr
Provedor de dados: 21
Autores: Koller, Martin.
Zuckermelonen sind keine einfache Kultur: Ob im geschützten Anbau oder im Freiland sind sie sehr krankheitsanfällig und die Rendite ist oft nicht genügend gut. In regenreichen Gebieten ist ein Freilandanbau nicht realistisch, da der Falsche Mehltau die Blattmasse oft zu früh zerstört. Im Folienhaus kann mit Zuckermelonen meistens nicht der gleich hohe Umsatz erreicht werden wie mit Tomaten oder Gurken. Trotzdem können die Melonen für Direktvermarkter ein interessantes Produkt sein, weil wirklich gut schmeckende Melonen im Sommer begehrt sind. Im Folientunnel erwiesen sich Schwefel und Kalium-Bicarbonat als erfolgreich gegen den Echten Mehltau ohne negative Auswirkungen auf den Ertrag und die Nützlinge.

Aggressivität von Fusarium avenaceum, Fusarium solani f. sp pisi und Mycosphaerella pinodes auf Wintererbsen (Pisum sativum L.) unter kontrollierten Bedingungen
Provedor de dados: 21
Autores: Šišić, Adnan; Bacanovic, Jelena; Bruns, Christian; Finckh, Maria R.
Climate change scenarios exhibit a definite warming trend (Schröter et al. 2005), and it will have an impact on crop management strategies. Increase in winter precipitation and higher temperatures favour soil borne pathogens and can lead to an increase in survival rate and to more rapid population buildup (Chakraborty et al. 2000). In recent years, one of the main reasons for declining production of summer pea in organic farming in Germany are foot and root rot pathogens (Pflughöft 2008). On the other hand, predicted increase in winter temperatures is expected to favour winter pea over summer pea varieties. The hope is also, that winter peas are less susceptible to root rot as summer peas. However, few data are available. The present study was carried out...

Bekämpfung der Blutlaus durch Freilassung von Blutlauszehrwespen aus Massenzucht
Provedor de dados: 21
Ziel des Projektes war die Erarbeitung eines Verfahrens zur Regulierung der Blutlaus (Eriosoma lanigerum HAUSM.), eines wirtschaftlich bedeutenden Schädlings im ökologischen Obstbau, gegen den es momentan keinerlei wirksame Bekämpfungsmöglichkeiten gibt. Hierzu wurde versucht, aus der Erfahrung vorangegangener Versuchsergebnisse ein Verfahren zur Bekämpfung der Blutlaus durch den Einsatz von Blutlauszehrwespen (Aphelinus mali L.) aus einer Nützlingszucht zu entwickeln und zur Praxisreife zu bringen. Die Zehrwespe ist ein natürlich vorkommender Gegenspieler, dem es aufgrund mangelnder Synchronisation zwischen Schädling und Nützling nicht rechtzeitig gelingt, den Schaden durch die Blutlaus zu verhindern.  Schwerpunkt des Projektes war die Entwicklung und...

Colza – La discipline reine des grandes cultures bio
Provedor de dados: 21
Autores: Daniel, C.; Dierauer, H.; Schärer, F.; Ramseier, H.; Bovigny, C.; Jossi, W.; Humphrys, C.
La culture du colza est risquée mais intéressante: elle permet de réaliser une marge brute aussi élevée qu’avec du blé. Et la demande d’huile de colza pressée à froid est nettement supérieure à l’offre. Les temps sont donc favorables pour ceux qui – bien préparés – désirent s’attaquer à la «discipline reine» des grandes cultures biologiques.  Depuis 2005, la surface des cultures biologiques de colza a passé en Suisse de 5 à 150 hectares. Une histoire à succès qui continue: les coopératives Biofarm et PROGANA cherchent de nouveaux producteurs pour couvrir la demande durablement forte d’huile de colza biologique pressée à froid.

The potential for slug control with ferric phosphate
Provedor de dados: 21
Autores: Horgan, A R.
Slug and snail damage, especially on young plants can mean serious economic loss for growers. Organic growers have in the past had few, if any, effective products to use for their control. Now ferric phosphate has recently gained organic status from the Organic Farmers and Growers organisation. Its unique mode of action, environmental profile and effectiveness against a range of slug and snail species will make this a first choice for all organic growers. The eventual breakdown components iron and phosphate, will contribute to the crop’s nutrient supply.

Beauveria bassiana strain ATCC 74040 (Naturalis®), a valuable tool for the control of the cherry fruit fly (Rhagoletis cerasi)
Provedor de dados: 21
Autores: Ladurner, E.; Benuzzi, M.; Fiorentini, F.; Franceschini, S.
Naturalis® is a bioinsecticide based on living conidiospores of the naturally occuring  Beauveria bassiana strain ATCC 74040. The entomopathogenic fungus acts primarily by  contact: once attached to the insect’s cuticle, the conidiospores germinate producing  penetration hyphae, which enter and proliferate inside the insect’s body. The fungus  invades and feeds on its host, causing its death due to dehydration and/or depletion of  nutrients. Several years of laboratory, semi-field and field studies showed that also Tephritid  flies (Ceratitis capitata, Rhagoletis cerasi, Bactrocera oleae) are susceptible to infection by  B. bassiana strain ATCC 74040. The results of efficacy trials conducted in 2004-05 are  reported. Naturalis was tested both alone and in...

Towards a sustainable whole-farm approach to the control of ergot
Provedor de dados: 21
Description  Concern has been mounting in recent years about the increasing problem of ergot contamination in wheat. This has resulted in greater numbers of grain loads being rejected for milling and in seed failing to reach the certification standards.     Recent changes in farming systems have been implicated, in particular the introduction of grass margins in arable fields, encouraged by CAP reform. The risk is that flowering grasses in the margins will become infected by ergot and act as a source of inoculum for the adjacent wheat crop as well as adding to the reservoir of ergots available to initiate the next season’s infection cycle. Other trends contributing to the increased ergot problem may include poor control of grass weeds because of increased...

In France Fruit production is cultivated on 140 thousand hectares, mainly conducted on intensive training system. Very few elements are available on low input training systems while they have to integrate the Global rule under the frame of Ecophyto 2018. In order to evaluate if another system of cultivation will be possible, a project has been developed to highlight the main factors to be integrated in low input training system. A low input multilocal experimental design has thus been investigated on apricot in two main regions of production: Rhone valley and Roussillon. A set of 9 common cultivars with 20 replications each, planted in a complete single-tree randomization design has been established.  As already observed in apple orchard, a larger set of...

Late blight, caused by the oomycete Phytophthora infestans (Mont de Bary) poses one of the most important risks in production of organic potatoes. Favourable late  blight conditions result in substantial losses in yield and quality in susceptible genotypes. In a series of field experiments between 2012 and 2015 at three organic  sites in northern and southern Germany 148 cultivars assessed the outcome of decades of german late blight resistance breeding. The phenotyping of this diversity  panel under natural conditions showed significant differences in the level of resistance within and across all maturity classes. These results were then used for a Single  Nucleotide Polymorpism (SNP) assay on a 12k Infinion chip to locate QTLs for late blight resistance....

Relevance of mycotoxins to product quality and animal health in organic farming
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Weißmann, Friedrich.
Organic farming is not generally more endangered by the risk of contamination of the products with mycotoxins than other farming systems. Knowledge about the influence of litter beddings on mycotoxin exposure of livestock is rare. Due to restrictions on silage additives and fungicides, organic farms are limited in their possibilities to prevent and to cure fungal diseases. But the organic production system offers several important factors for lowering infections with mycotoxin producing fungi.

Pollen beetles (Meligethes sp.) are important pests in oilseed rape (Brassica napus). In  our study we wanted to determine which landscape structures have an influence on pollen beetle  population in early spring. The dynamics of pollen beetle population and the damages on rape were  studied on field scale level with 100 sampling points per field and on landscape scale level with 18  organic oilseed rape fields which differed by the complexity of the surrounding landscapes. The  number of pollen beetle was strongly correlated with the distance to a forest. At the beginning of  the flight period more pollen beetles were found close to the forest, later they migrated to the rest of  the field. In addition, agricultural practices appeared to be determinant...

Zwei verschiedene Fallentypen für Drosophila suzukii im Vergleich
Provedor de dados: 21
Autores: Cahenzli, Fabian; Daniel, Claudia.
In einer Beerenhecke in Frick wurden zwei Fallentypen bezüglich ihrer Fangeffizienz der Kirschessigfliege D. suzukii verglichen: (1) die kommerziell erhältliche Gasser-Becherfalle der Firma Riga mit weissem Deckel und (2) die kommerziell erhältliche Profatec-Falle mit rotem Deckel. Die Fängigkeit beider Fallentypen unterschied sich nicht signifikant, obwohl aus Literaturangaben bekannt ist, dass weiss weniger attraktiv für D. suzukii ist als rot. Bei der Becherfalle wurde die ungünstigere Farbe eventuell durch die Bauweise kompensiert. Da sich die Fängigkeit der Einweg-Becherfalle nicht signifikant von der wiederbefüllbaren Profatec-Falle unterschied, können beide Fallen für das Monitoring und den Massenfang von D. suzukii empfohlen werden.

In laboratory, growth chamber, micro-plot and small-plot field trials, 53 copper-free  preparations (CFPs) were examined for their potential to control potato late blight  (PLB) caused by Phytophthora infestans (PI). In-vitro, 43% of the CFP inhibited the  germination of sporangia or the mycelial growth of the pathogen completely. In growth  chamber trials, 21% of them reduced PI foliar blight of tomato seedlings by at least  80%. In contrast, in small-plot field trials with potatoes under practice like applications,  none of the CFPs sufficiently controlled the disease. Even in micro-plot field trials with  applications twice a week the efficacies did not exceed 60%. With in-vitro tests we  showed that the reason for the insufficient performance of the...

Autores: Kelderer, Markus; Casera, Claudio; Lardschneider, Ewald.
The apple variety Braeburn is very popular among the organic apple growers in South Tyrol. Braeburn brings  high and regular yields and good prices at the north European fruit and vegetable market. Braeburn is quite  susceptible to scab and mildew. To regulate this latter disease the organic orchardists use mainly sulphur  products. Braeburn however is sensitive to sulphur treatments. Mainly during summer at high temperatures  the leaves of Braeburn treated with sulphur develop a yellowish colour and necrotic spots. A field-trial was  carried out for 2 years to investigate which sulphur formulations and application techniques give less phytotoxic  problems to leaves and fruits of the apple variety Braeburn. The results show only small differences  between...

Tree shading: an efficient method to control alternate bearing?
Provedor de dados: 21
Autores: Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
Conventional and integrated fruit growers, but not organic producers, have the possibility  to use thinning agents (e.g. benzyl adenine), which allow crop regulation at a relatively late  stage (10-16 mm fruit size). A few surveys have shown that by reducing net  photosynthesis after blossom, June fruit drop increases. This could be an interesting new  approach for organic apple orchards. Since 2003, different trials have been carried out at  the Laimburg Research Station on the variety Golden Delicious rootstock M9 to devise a  method for practical use by fruit growers. Unfortunately, there are still several constraints  to the practical application of the shading method, not least because it does not sufficiently  reduce alternate fruit bearing in the...

Neben der Verbesserung der Stresstoleranz per se, stellt die Nutzung der Mykorrhiza eine Möglichkeit zur Verbesserung der Stresstoleranz dar.  Das Ziel des Vorhabens war es daher genetische Unterschiede des Brotweizens (Triticum aestivum) bezüglich der Fähigkeit zur Symbiose mit wurzelendopytisch...

Autores: Spornberger, A.; Steffek, R.; Stich, K.; Jetzik, K.; Scheiblauer, J.; Altenburger, J.; Halbwirth, H.; Gosch, C.
Soil-borne pathogens, above all Verticillium sp. cause plant losses and yield decreases in many Austrian strawberry fields, also in organic farming systems; in a research project possibilities to resolve this problem were examined. In a field trial, which was started 1998, organically managed and differently fertilized plots (green compost, manure, hornchips) were compared to an unfertilised control plot and to two mineral fertilized and conventionally treated plots; the differences in field characteristics of strawberries in 2004 and 2005 were low, but differences in storage and biochemical characteristics could be seen in 2005. Some new cultivars tested as alternative to the very sensitive 'Elsanta' planted in 2005 on several farms showed a higher...

Investigations on alternative substances for control of apple scab - results from sanitation trials
Provedor de dados: 21
Autores: B., Pfeiffer; S., Alt; C., Schulz; B., Hein; C., Häfner; A., Kollar.
The intention of this research project, which was supported within the "Bundesprogramm Ökologischer  Landbau", was to look for alternatives in organic fruit growing to control apple scab, Venturia  inaequalis. One important part of the investigations was the application of different substances like  microbiological nutrient media, enzymes usually used for production of fruit juices and organic fertilizers  on their effect on the ascospore potential on depots of fallen leaves. Some substances like  TRYPTIC SOY BROTH increased the decomposition of the leaves significantly, other like BACTOFIL B  and HUMOFIX showed nearly no effect on the decomposition, but reduced the ascospore potential in  early spring by 80 % compared to the untreated control.

Thinning effect of lime sulphur applied during blossom with the overhead irrigation system in comparison to the sprayer
Provedor de dados: 21
Autores: Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
A large number of organic fruit-growers in South Tyrol regulate scab with scab-stop treatments using the overhead irrigation system. They use mainly lime sulphur, because it is particularly suitable for scab stop treatments. Treatments during blossom can also thin the flowers. The aim of the field-trials was to understand if lime sulphur applied with the overhead irrigation system gives the same thinning effect like the normal application with the sprayer. The results from the 2 years of trials show that there is no significant difference between the two application systems. Other factors like the influence of the different climatic parameters in each year play a more important role.

L’essai réalisé sous abri froid en fin de culture de fraise précoce a permis de mettre en évidence l’intérêt de certains produits pour limiter les attaques de D. suzukii. L’efficacité du Success4 (Spinosad) a été confirmée ; ce produit doit être utilisé avec précaution car il est toxique pour les auxiliaires et les pollinisateurs, et son DAR est de 3 jours. Pyrévert et surtout PréVam ont montré une efficacité nettement insuffisante. Les deux produits microbiologiques Naturalis (Beauveria bassiana) et Solbac (Bt) ont quant à eux apporté les meilleures protections (entre 50 et 70% d’efficacité), au moins équivalentes au Success4.

Haben ökologische Ausgleichsflächen positive Effekte auf die Laufkäferfauna? In zwei unterschiedlich genutzten Landschaften sind wir dieser Frage nachgegangen. Die Ergebnisse des ersten Erhebungsjahres 1997 zeigen, dass die Arten- und Individuenzahlen der Laufkäfer innerhalb der gleichen Lebensraumtypen stark variieren können. Dies kann teils auf die Qualität dieser Elemente sowie auf Standortverhältnisse und Landschaftseinbettung zurückgeführt werden. Im Ackerbaugebiet wurden mit ökologischen Ausgleichsflächen insbesondere mit Buntbrachen deutlich positive Auswirkungen auf die Laufkäfer erzielt. Die wenig intensiv und extensiv genutzten Wiesen im Futterbaugebiet hingegen unterschieden sich weniger deutlich von den intensiv genutzten Wiesen und Weiden....

Efficient Multi-location Testing of Scab Resistant Cultivars for Organic Apple Production in Switzerland
Provedor de dados: 21
Autores: Weibel, Franco; Schmid, Andi; Häseli, Andreas.
The market and production of organic apples is growing worldwide. Most of the production occurs on freshly converted orchards with cultivars very sensitive to apple scab (Venturia inaequalis) that in humid conditions need an intensive plant protection program. For the future development of organic fruit growing towards a credibly sustainable production it is necessary to replace these cultivars with scab resistant or tolerant cultivars. Cultivar testing under organic growing conditions is therefore an important task. We describe our testing concept that consists of precision trials where cultivars are tested with an without aphid control and with and without crop load regulation. In parallel, we carry out on-farm trials with the most promising cultivars on...

Resistant barley varieties may facilitate control of Ramularia leaf spot
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Sindberg, Susanne A.; Willas, Jakob.
Ramularia leaf spot (RLS) is widely present in Denmark nowadays and has the potential to reach severity levels high enough to cause economic damage. The results of multi-location surveys and field trials of several years suggest that varietal resistance can be an efficient means for controlling RLS. The spring barley cultivars most affected by RLS possess mlo-resistance against powdery mildew while the least affected ones do not. Other mildew resistances as well as varietal susceptibility to other foliar diseases were not clearly related to the RLS reaction pattern of neither spring- nor winter barley cultivars. Promising RLS resistance donors may be the spring barleys Power, Helium, Isabella, Nathalie, Cruiser and Isotta and the winter barleys Lonni,...

Ertrags- und Qualitätssicherung im ökologischen Kartoffelbau: Vorkeimung, Stickstoffversorgung, Kupferbehandlung
Provedor de dados: 21
Autores: Paffrath, Andreas; Stumm, Christoph.
Beim Vergleich der anbautechnischen Maßnahmen Vorkeimung, organische Stickstoffdüngung und Kupferbehandlung sowie deren Kombinationen untereinander erwies sich im Mittel der Jahre die organische Stickstoffdüngung als wichtigste ertragssichernde Maßnahme. Durch den deutlichen Wachstumsvorsprung vorgekeimter Pflanzknollen war die Vorkeimung bei Auftreten der Krautfäule im Jahr 2005 beste Einzelmaßnahme. Bleibt die Krautfäule aus (2006), sind durch Vorkeimung keine höheren Erträge zu erwarten. Eine alleinige Behandlung der Bestände mit Kupfer stellte auch im Jahr mit Krautfäuleinfektion keine ertragssichernde Maßnahme dar. Erst in Kombination mit verbesserter Nährstoffversorgung und/oder Vorkeimung waren ertragssteigernde Effekte zu beobachten.

Effect of Barley-Legume Intercrop and Major Nutrients on Disease Frequency in an Organic Farming System
Provedor de dados: 21
Autores: Kinane, Dr. J.; Lyngkjær, Dr. M.
The effect of barley-legume intercrop in an organic farming system on disease incidence was investigated over two years. Two barley varieties were intercropped with lupin, faba bean or pea. Several diseases were observed: ascochyta blight (Mycosphaerella pinodes) on pea, brown leaf spot on lupin and chocolate spot (Botrytis) on bean. On barley net blotch (Pyrenophora teres), brown rust (Puccinia hordei) and powdery mildew (Blumeria graminis f. sp. hordei) (in order of incidence) were detected. A general reduction in disease was observed in all intercrop systems compared to the corresponding monocrop, but the reduction was only statistically significant in the cases of brown leaf spot on lupin, ascochyta blight on pea and net blotch on barley.  The above...

The effects of Quassia extract on eggs and larvae of the apple sawfly Hoplocampa testudinea were studied in the laboratory. The efficacy of this extract was mainly due to an oral toxicity to neonate sawfly larvae. The main active ingredients, Quassin and Neoquassin, were tested sepa-rately as pure substances. While Quassin had a considerable efficacy also on older larvae, Neo-quassin was less efficient in this case. Since Quassin and Neoquassin were found in different Quassia sources in varying relations to each other and had different efficacy, they have to be considered separately in the definition of extract quality by the content of active ingredients. This requires the application of Quassia extracts before larval hatch. It was shown that low...

Understanding Trichoderma in the root system of Pinus radiata: associations between rhizosphere colonisation and growth promotion for commercially grown seedlings
Provedor de dados: 21
Autores: Hohmann, Pierre; Jones, E. Eirian; Hill, Robert A.; Stewart, Alison.
Two Trichoderma isolates (T. hamatum LU592 and T. atroviride LU132) were tested for their ability to promote the growth and health of commercially grown Pinus radiata seedlings. The colonisation behaviour of the two isolates was investigated to relate rhizosphere competence and root penetration to subsequent effects on plant performance. Trichoderma hamatum LU592 was shown to enhance several plant health and growth parameters. The isolate significantly reduced seedling mortality by up to 29 %, and promoted the growth  of shoots (e.g. height by up to 16 %) and roots (e.g. dry weight by up to 31 %). The introduction of LU592 as either seed coat or spray application equally improved seedling health and growth demonstrating the suitability of both application...

Lutte contre le Bremia de la laitue en pépinière et sous abri froid : compte-rendu d'essai 2006

Autores: Lambion, Jérôme; Mounier, Jean-Michel.
L'objectif de ces essais est de tester, en pépinière et sous abris froids, différents produits susceptibles d'être utilisés en AB, pour lutter contre le mildiou de la laitue.  En pépinière, seul Cuivrol apporte une protection suffisante contre Bremia. Aucune phytotoxicité n'apparaît à la dose testée.  En culture, une attaque assez faible de mildiou malgré une inoculation et le maintien de conditions relativement confinées n'a pas permis d'apporter de conclusions très nettes concernant la protection apportée par les produits. La comparaison des fréquences d'attaque en culture et lors de la récolte montre que seuls Mycosin et Cuivrol permettent de limiter l'attaque de Bremia, pour une pression faible en maladie. Même si la phytotoxicité a été fortement...

Selective flowers to enhance biological control of cabbage pests by parasitoids
Provedor de dados: 21
Autores: Géneau, Céline E.; Wäckers, Felix L.; Luka, Henryk; Daniel, Claudia; Balmer, Oliver.
Habitat management is an important element in sustainable agriculture and can be used to maximize a range of ecosystem services that support crop production. An important example of such ecosystem services is biological control of pests which can be enhanced by providing arthropod natural enemies with suitable floral resources. The potential risk of this approach, however, is that flowering plants may enhance the fitness of the targeted pests as well. We conducted experiments to identify selective plant species that would improve the longevity and parasitization rate of the parasitoid wasp Microplitis mediator without benefiting its host pest, the cabbage moth Mamestra brassicae. Effects on longevity were also assessed for Diadegma fenestrale, a generalist...

Thirteen winter wheat composite cross populations originating from one population but with differing histories over six years and three reference varieties were compared for yield, disease occurrence, as well as phenotypic diversity. The populations performed similarly and often better than the reference varieties in terms of yield and had lower incidence of disease. The populations are also phenotypically diverse and differ among each other, indicating that they have maintained a high degree of diversity over time and in varying locations, but most likely also diverged from each other.

Organic Centre Wales Technical Note 4: Biology and management of slugs
Provedor de dados: 21
Autores: Anon,.
Slugs are the most common and widespread pest affecting all farmers and growers. There are 29 species of slugs in the UK. The most destructive are from the Deroceras, Arion and Malix groups. Very few crops are unaffected as slugs are polyphagus and feed throughout the year whenever conditions are cool/warm and damp. With FYM &amp; green manures, soil organic matter levels are increased which favours slugs. Snails tend to be less important, but can cause problems in gardens and on cane fruits.  This technical note discusses natural enemies of slugs, nature of damage, life history and control measures, and lists sources of further information.

Das Projekt bietet ein schönes Beispiel, bei dem sich die Betriebsmerkmale so deutlich in den Baum- und Fruchtmerkmalen widerspiegeln. Die Bildschaffende Methoden waren eine gute Hilfe um die Zusammenhang zwischen Baum, Frucht und Kulturmaßnahmen zum Ausdruck zu bringen. Die Arbeit an den Versuchsfragen hat gezeigt, dass Bäume eine gewisse Vitalität brauchen, um eine gute Fruchtqualität zu erzielen. Dieses ist möglich durch die Anwendung allgemein bekannter Schnitt- und Ausdünnungsmaßnahmen , die auf einen vitalen Baum mit beherrschter Wuchskraft abzielen. Die unterschiedlichen Pflanzabstände mit den entsprechenden Unterschieden im Wachstumsverhalten lassen als noch keine eindeutiges Unterschied sehen.

Chancen und Grenzen der Biofumigation für die Bekämpfung  pflanzenparasitärer Nematoden
Provedor de dados: 21
Autores: Hallmann, Dr. Johannes; Buck, Holger; Rau, Florian; Daub, Dr. Matthias; Schütze, Dr. Wolfgang; Grosch, Dr. Rita; Schlathölter, Michaela.
Biofumigation is considered a promising nematode control alternative. In vitro tests  confirmed the high nematicidal properties of isothiocyanates, the driving compounds  of biofumigation. Its potential under temperate climate conditions was tested on a  commercial farm. The tested biofumigation treatments reduced population densities of  Pratylenchus spp. but had little effect on Meloidogyne hapla. The latter was most likely  due to the good status of the tested varieties. To further optimize the biofumigation  system non-host crops with high concentration of glucosinolates have to be selected.

The efficacy of the processed kaolin “Surround WP” to control olive fruit fly, Bactrocera oleae Gmelin, field infestations was investigated in east Calabria. The preliminary results showed that fruit infestation levels were significantly reduced on kaolin-treated trees compared with untreated trees. The promising results of these experiments points to the feasibility of using particle film technology composed of a non-toxic material, to avoid olive fly damage as an alternative to the applications of rotenone in organic orchards. Finally, kaolin treatment unaffected the nutritional and sensory quality parameters of the corresponding virgin olive oils obtained by a laboratory scale olive mill, thus satisfying the present quality requirements.

Mitigation of subsoil recompaction by light traffic and on-land ploughing. I. Soil response
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.; Rüegg, K.
Mechanically loosened subsoil has been shown to be prone to recompaction. We evaluated the degree of recompaction of a sandy loam mechanically loosened to a depth of 35 cm in 1997 and again in 1998. Perennial grass/clover was grown with limited traffic intensity in 1999 and 2000. The recompaction experiment was conducted in 2001 and 2002 when the soil was grown with oat and winter wheat, respectively. On-land ploughing was compared with traditional mouldboard ploughing with the tractor wheels in the furrow. In addition, the loosened plots were either light trafficked (&lt;6 Mg axle load and &lt;100 kPa inflation pressure) or heavy trafficked (10-18 Mg axle load and ~200 kPa inflation pressure), respectively. The soils loosened by non-inversion deep tillage...

This shortpaper sums up some main results of a study on biodynamic carrot growing in 1996. These results based on data from a survey of 45 farmers growing carrots for continuous sale in winter. The questions concerned the general site conditions such as soil type, pre-crop and green manure and special aspects of growing like cultivar, date of sowing and harvest. Furthermore the farmers were asked about application of fertilizer and biodynamic preparations. Estimated yields, storage conditions and specific features were taken into account, too.

Intercropping cereals and grain legumes: a farmer’s perspective
Provedor de dados: 21
Autores: Prins, U.; Wit, J. de.
Intercropping cereals and grain legumes show potential for organic agriculture in many ways. However, the use of land equivalent ratio (LER) as a measure for calculating the cropping advantage of intercrops over sole crops is too simple: neglecting weed suppression, yield reliability, grain quality, and minimum profitable yield, which are all relevant fac-tors from a farmer’s perspective. Only when the crop selection for the mixtures is carefully done, and crops are grown on the right soil in the right rotation, can intercropping be made to profit.

Identification of measures for prevention of black spots in organically produced stored carrots
Provedor de dados: 21
Autores: Koehl, Juergen; Kastelein, Pieter; Elderson, Janneke; Blok, Wim J.
In the Netherlands winter carrot for the fresh market is a cash crop for many organic growers of field vegetables. In the last few years blackish spots have been observed during storage of carrot roots. An inventory was carried out in 2001/2002 and 2002/2003 including in total 42 carrot lots from 22 growers. Statistical analysis was performed by multiple regression analysis to identify factors and variables that best explained the occurrence of black spots on stored carrots.  Rhexocercosporidium carotae was the dominating pathogen in black spots of carrots harvested in 2001. From carrots harvested in 2002, Alternaria radicina was isolated most frequently, followed by A. dauci and R. carotae. Multiple regression analysis indicated that the occurrence of R....

Kirschenfliege: Wie sie ihre Feinde austrickst
Provedor de dados: 21
Autores: Kuske, Stefan; Grunder, Jörg; Daniel, Claudia; Wyss, Eric.
Seit Jahrzehnten wird intensiv nach alternativen Kontrollmassnahmen zur chemischen Bekämpfung der Kirschenfliege gesucht (Boller und Remund 1980). Bis heute leider nur mit bescheidenem Erfolg für die Praxis. Der Einsatz insektenparasitischer Nematoden zur vorbeugenden Bekämpfung der im Boden überwinternden Schädlinge hat jüngst aber neue Hoffnungen geweckt. Wieso sich diese sonst so zuverlässigen Nützlinge an der Kirschenfliege ebenfalls die Zähne ausbeissen, soll im vorliegenden Artikel aufgezeigt werden.

Erfassung der Fusarium- und Mykotoxinkontamination von Bio- und IP-Weizen und Entwicklung von Massnahmen zur Minderung des Befalls und des Mykotoxin-Belastungsrisikos
Provedor de dados: 21
Der Befall von Getreide mit Pilzen der Gattung Fusarium wird durch verschiedene Anbaumassnahmen wie die Fruchtfolge, die Bodenbearbeitung und die Sortenwahl beeinflusst. Am besten untersucht ist Fusarium graminearum (FG) und das Toxin Deoxynivalenol (DON). FG und DON treten bei Weizen speziell nach Maisvorfrucht und bei Verbleiben der Maisreste auf der Erdoberfläche, stark auf. Mit diesen zwei Risikofaktoren genügen auch die besten Sorten nicht, um kritischen Kontaminationen vorzubeugen. Durch die Elimination der Befallsquellen, die Förderung der Rotte und dem Einsatz von Antagonisten zur Bekämpfung von FG auf Maisresten und Massnahmen zur Verhinderung der Askosporenverbreitung, wie z.B. der Einarbeitung der Maisreste, könnten Infektionen verhindert...

Kaolin clay, a new method for protecting plants against the peach aphid Myzus persicae Sulzer by creating a mineral barrier
Provedor de dados: 21
Autores: GARCIN, A.
The peach aphid Myzus persicae Sulzer is one of the major pests found on peach trees. The CTIFL has been running tests since 2005 to assess the efficacy of Surround® WP, a product containing kaolin that is applied either at the time of leaf fall to prevent winter egg-laying or in the spring to prevent the establishment of fundatrices. The period of application and the production system (organic or conventional) were tested, allowing a comparison with chemical aphicides. The clay product used at leaf fall reduced winter egg-laying by about 50%. Autumn application of Surround® alone was not sufficient to control aphid colonies in the spring, but it could be used as part of a supervised control strategy, combined with the application of mineral oils in late...

Impact of foliar diseases in organically grown barley: Influence of fertilization, nutrient content in leaves, varietal disease resistance characteristics and yield potential
Provedor de dados: 21
Autores: Hovmøller, M.S.; Berntsen, J.; Kristensen, K.
Significant increase in severity of powdery mildew,leaf rust and net blotch with increasing N-content in plant leaves 30 days after germination (all years where the relevant diseases were present at a substantial level). This may explain:  · Most of the environmental main effects (field) on disease.  · Effect of treatments, i.e., treament 4 resulted in reduced N/increased K content in leaves, which coincided with reduced levels of disease.    We observed no clear effect of P, Ca, S, and Zn content in leaves on disease. Micronutrients as Cu, Mo and Mn showed significant effects on powdery mildew in one year but not the other; further interpretation may not be possible due to inter-correlation among the effect of micro-nutrients.

A new integrative assessment indicator for damage caused by major pests and diseases in the vineyard
Provedor de dados: 21
Autores: Delbac, L; Constant, N; Laveau, E; Thiéry, D; Smits, N; Roudet, J; Mérot, A; Wéry, J; Fermaud, M.
An original and integrative evaluation indicator has been developed to quantify the cumulated damage from major pests and diseases affecting grape bunches: downy mildew, powdery mildew, gray mould and tortricid moths. It made it possible to estimate the associated crop losses and to relate them to the plant protection strategy in different modes of production (organic farming, in-transition, conventional). Thus, overall plant losses were higher in 2012 than in 2011. The in-transition growers’ strategy, with reduced copper doses but increased numbers of sprays, led to a 20% increase in average severity on bunches (essentially due to Downy mildew). The more pragmatic approach of experienced organic growers and conventional ones (higher doses and fewer...

Trophobiosis Theory: A Pest Starves on a Healthy Plant
Provedor de dados: 21
Autores: Paull, John.
Pests shun healthy plants. Pesticides weaken plants. Weakened plants open the door to pests and disease. Hence pesticides precipitate pest attack and disease susceptibility, and thus they induce a cycle of further pesticide use.     This is the essence of Trophobiosis Theory, a thesis presented by Francis Chaboussou, an agronomist of the France’s National Institute of Agricultural Research (INRA), in “Healthy Crops: A New Agricultural Revolution”. After two decades, this important book is finally available in English.    Plant pathologist Chaboussou (b.1908 - d.1985) saw with a clear eye that just as there are iatrogenic, doctor-caused, medical problems, likewise there are agrogenic, farmer-caused, agricultural problems.

Im Jahr 2010 wurde in der Ostschweiz bei einzelnen extensiv oder biologisch bewirtschafteten Apfelbäumen noch vor der Ernte ein starker Blattfall beobachtet. Die abgefallenen Blätter hatten grauschwarze Flecken und eine gelbe Verfärbung. Mikroskopische Untersuchungen zeigten, dass die Pilzkrankheit Marssonina coronaria den Schaden verursachte. Diese Apfelkrankheit war in der Schweiz vor 2010 nicht bekannt, breitet sich seither aber aus.

Schwellenwerte und weitere Entscheidungshilfen bei Befall mit Zwergsteinbrand (Tilletia controversa) und Steinbrand (Tilletia caries)
Provedor de dados: 21
Autores: Dressler, Markus; Voit, Benno; Büttner, Peter; Killermann, Berta.
Beim Zwergsteinbrand zeigte sich, dass bei günstigen Infektionsbedingungen bereits ca. 50 Sporen in 10 g Boden zu einem starken Befall am Erntegut führen. Bei den verwendeten Sorten konnten keine nennenswerten Unterschiede im Befall festgestellt werden. Ein Schwellenwert von 20 Sporen/Korn ist nach den derzeitigen Ergebnissen auch für Zwergsteinbrand ausreichend. Da ein Abschätzen der Winterwitterung schwer möglich ist, wäre ein Grenzwert für das Infektionspotenzial im Boden, vor der Weizen- oder Dinkelsaat, durchaus überlegenswert. Dieser lässt sich aber nach einem einjährigem hohen Befall noch nicht festlegen.   Der Steinbrandbefall ist stark von den Auflaufbedingungen abhängig. Nach zwei vorliegenden Versuchsjahren hat sich gezeigt, dass neben einer...

Breeding for symbioses – Mycorrhizae as a case study
Provedor de dados: 21
Autores: Hohmann, Pierre; Backes, Gunter; Thonar, Cécile; Messmer, Monika.
Plant associated soil microbes are known to play an important role in the expression and stability of certain plant traits such as nutrient use efficiency and disease resistance. Arbuscular mycorrhizal fungi (AMF) form one of the primary mutualistic plant-microbe symbioses. Besides known benefits such as improved nutrient mobilisation (mainly phosphorus and zinc) and tolerance against abiotic stresses (mainly drought), an increasing number of studies highlight a significant role of AMF in the mediation of disease resistances and priming mechanisms. Individual reports have shown enhanced levels of defence-related compounds (such as glucanases, chitinases and phenolics) in mycorrhizal plants, and there is first evidence of certain phytohormone pathways (in...

Allelopathic effects of Rumex obtusifolius leaf extracts against native grassland species
Provedor de dados: 21
Autores: Zaller, Johann G.
In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions. To test this hypothesis, in a series of laboratory and field experiments aqueous extracts of green R. obtusifolius leaves were sprayed on seeds of 14 herbaceous plant species (graminoids, non-leguminuous forbs and leguminuous forbs) commonly native to perennial grasslands and its effects on seed germination compared with those with tap water spraying. An allelopathic effect was defined as inhibitory influence of Rumex extracts on seed germination relative to tap water. Generally, results of the laboratory experiments...

Primary scab control using a “during-infection” spray  timing and the effect on fruit quality and yield in organic  apple production
Provedor de dados: 21
Autores: Jamar, Laurent; Cavelier, Marc; Lateur, Marc.
Organic apple production in Europe depends to a great extent on the use of copper fungicides for scab control (Venturia inaequalis). The objective of this 6-year study (2003-2008) conducted in Belgium was to determine measures for reducing the use of copper fungicides in organic apple production. The effectiveness of a “during-infection” spray strategy using wettable sulphur (with or without copper), lime sulphur, potassium bicarbonate, silicon and five natural plant extracts (orangepeel, soapbark, tea seed, quinoa seed and grapefruit seed) for controlling primary scab was investigated in a split-plot field experiment. Four apple cultivars that express a gradient of partial scab resistance were included: a high scab-susceptible cultivar (cv. ‘Pinova’), a...

Die Untersuchung ergab, dass  ► die Rohproteingehalte mit einem Mittelwert von 10,0% sehr niedrig lagen. 44,3% der Probengrundgesamtheit lag in den Klassen &lt;10%. Nur 8,2% der Proben wiesen Gehalte über 11,5% Rohprotein auf.  ► mit steigendem Stickstoff-Gehalt der Proben auch deren Schwefel-Gehalt zunahm. Der mittlere S-Gehalt betrug 0,127 %. Bezüglich der N:S-Verhältnisse ergaben sich...

Modern approaches for breeding high quality apples with durable resistance to scab, powdery mildew and fire blight
Provedor de dados: 21
Autores: Kellerhals, Markus; Patocchi, Andrea; Duffy, Brion; Frey, Jürg.
New methods to allow for more precise selection of tree and fruit characters in breeding  programmes were developed in recent years. Marker-assisted selection (MAS) is common  practice in the ACW apple breeding programme at Wädenswil. Genetic markers can  reduce the number of plants and the time required for evaluation, thus new varieties  become commercially available sooner. How can this molecular selection method  reasonably be applied in an apple breeding programme? Application of phenotypic and  molecular selection techniques in the ACW apple breeding programme and results are  presented.

Ecology of entomopathogenic fungi in agroecosystems
Provedor de dados: 21
Autores: Meyling, Nicolai V.
Fungi that infect insects have received considerable attention by scientists for their potential for biological control of pests. Many research projects have focussed on the selection of virulent strains for target pests and their development as biological control agents. In contrast, surprisingly little is known about the fundamental ecology of most of these fungi in nature. This knowledge is essential in order to receive the most ecosystem services provided by entomopathogenic fungi in agricultural production. Knowledge of the basic ecology of the fungi is also necessary to include them in conservation biological control. In this biological control strategy, agricultural practices and/or habitat manipulations are applied to the farming system to favour...

Phosphonat zur Bekämpfung der Phytophthora infestans bei Kartoffeln – eine mögliche Alternative zu Kupfer?
Provedor de dados: 21
Autores: Krebs, Heinz; Vogelgsang, Susanne; Forrer, Hans-Rudolf.
Since more than hundred years, copper-products are used to control late blight of potato, caused by Phytophthora infestans. However, the heavy metal copper accumulates in the soil and affects soil flora and fauna. For this reason, copper agents are listed in the EU only until the end of November 2016. In conventional and integrated farming, copper products have been replaced by synthetic fungicides. In organic production, intensive research is conducted to develop effective alternatives that could replace copper fungicides.  In Germany, plant strengthening agents based on phosphonate are allowed to be used in organic viticulture until the end of the flowering period to control downy mildew. However, if vine plants are treated with phosphonate after...

Autores: Manici , L.M.
APPLE  • Apple replant disease in central Europe has a consistent biotic origin which is responsible for about 30% of growth reduction in multi-generation orchards. Cylindrocarpon-like fungi and Pythium spp. were shown to be primarily responsible for plant growth reduction, which was confirmed as main indicator of apple replant disease.   • Pyrosequencing analysis of rhizospheric microbial communities associated to replanted orchards confirmed that Cylindrocarpon-like fungi are largely associated to replant disease; however, it also evidenced that several bacterial and fungal genera indigenous to replanted orchards are positively correlated to plant growth. This suggested that many are the indigenous resource to be exploited for increasing plant...

Pollen beetles (Meligethes sp.) are important pests in oilseed rape (Brassica napus).  In our study we wanted to determine which landscape structures have an influence on pollen beetle population in early spring. The dynamics of pollen beetle population and  the damages on rape were studied on field scale level with 100 sampling points per field and on landscape scale level with 18 organic oilseed rape fields which differed by  the complexity of the surrounding landscapes. The number of pollen beetle was strongly correlated with the distance to a forest. At the beginning of the flight period more pollen beetles were found close to the forest, later they migrated to the rest of the field. In addition, agricultural practices appeared to be determinant for...

Autores: Schweinzer, Agnes; Gollner, Gabriele.
Lucerne (Medicago sativa L.) is known for its high water consumption and is one of the most important forage legumes. However lists of varieties are still lacking information about its water use. Therefore this study focused on the evaluation of four varieties` water economy and yield stability by comparing plant water characteristics to plant production characteristics under field conditions. Relative water content (RWC) turned out to be the most proper parameter for analyzing lucerne`s water use regarding a significant variety effect. Nevertheless further research will be indispensable to give explicit cultivar recommendations for breeding purposes.

Fungicidal preparations from Inula viscose
Provedor de dados: 21
Autores: Cohen, Y.; Baider, A.; Ben-Daniel, B.; Ben-DanieI, Y.
Inula viscosa is a perennial plant native to the Mediterranean Basin. Extracts made from the shoots of this plant exhibited a strong fungicidal activity in vitro and in vivo. TLC analyses revealed at least 7 fungicidal compounds. Most are lipophilic. When such extracts were sprayed on the leaf surface of crop plants they effectively controlled downy mildew in grape, cucumber and tabacco; late blight in potato and tomato; gray mold in cucumber and tomato; and, powdery mildew in cucurbits and cereals. Field experiments conducted with grape vine resulted in effective control of Plasmopara viticola. The data suggest that Inula viscosa is a useful source of herbal fungicidal preparations for agricultural use.

Control of the woolly apple aphid (Erisoma lanigerum Hausm.) by releasing earwigs (Forficula auricularia L.) and support oil applications - an interim report of first year results
Provedor de dados: 21
Autores: Toups, I.; Zimmer, J.; Trautmann, M.; Fieger-Metag, N.; Buchleither, S.; Bathon, H.
The woolly apple aphid (Erisoma lanigerum Hausm.) has been recognised for some years as  a serious pest in organic fruit growing where they may cause severe economic damage due  to a lack of control strategies. Based on preliminary results a new project has been started in  2007 testing combinations of releasing earwigs and oil applications in order to develop an onfarm  control strategy. In this paper we present preliminary results of the first year of the  project´s field trials. They showed good efficacies for applying oil preparations by brush. The  efficacy of releasing earwigs depended on the infestation intensity.

Contaminants in manure - a problem for organic farming?
Provedor de dados: 21
Autores: McKinnon, Kirsty; Serikstad, Grete Lene; Eggen, T.
This work addresses possible ways in which animal manure might become contaminated by undesirable elements and how such manure might pose a risk to the health of soil organisms, animals, plants and humans. Research has shown that the pathways of organic compounds such as veterinary medicines and pesticides may be unpredictable and that undesirable elements can be transferred to the food chain. The basic principles of organic farming, in this case specially related to the principles of health, ecology and care, imply that special attentionshould be given to precaution and responsibility. These are key concerns in the management of organic farming. Taking these principles seriously, would mean a more restrictive practice on the use of animal manure from...

Provedor de dados: 21
Autores: Fleck, Michael; Hagel, Ingo; Meier-Ploeger, Angelika.
Mit dem Ziel, die Marktsituation für den Verbraucher zu beschreiben, wurden Proben von Speisemöhren des Anbaujahres 1996 aus der biologisch-dynamischen und konventionellen landwirtschaftlichen Praxis gesammelt. Dabei zeichneten sich die biologisch-dynamischen Möhren durch weniger Weichfäule und Verdunkelung im Stresslagertest als die konventionellen aus und geringere Verluste nach 120-tägiger Lagerung unter Praxisbedingungen. Bei den Proben der biologisch-dynamischen Betriebe wurden höhere Trockensubstanzgehalte festgestellt sowie höhere Gehalte an Saccharose und Gesamtzucker; die Nitratwerte der DEMETER-Möhren lagen weit unter denjenigen der konventionellen.

Effect of alternative strategies for the disinfection of tomato seed infected with bacterial canker (Clavibacter michiganensis subsp. michiganensis)
Provedor de dados: 21
Autores: Kasselaki, A. M.; Goumas, D.; Tamm, L.; Fuchs, J.; Cooper, J.; Leifert, C.
Currently there is a lack of effective seed treatments for bacterial pathogens, with Cu-based compounds (the only chemical treatments permitted under organic farming standards) only providing partial control.  The aim of this study was to quantify the effect of alternative treatments for the control of bacterial canker (Clavibacter michiganensis subsp. michiganensis), a major seed-borne bacterial disease in tomato.  Treatments assessed were acidified nitrite (a treatment previously shown to control the seed-borne fungal disease Didymella lycopersici), antagonistic strains of Bacillus spp. and compost extracts, which were not previously evaluated as treatments for seed-borne diseases. Efficacy of treatments was determined in a seed disinfection assay....

Searching for the cause of clover fatigue
Provedor de dados: 21
Autores: Serikstad, Grete Lene; Magnusson, Christer; Brodal, Guro; de Boer, Anne.
There is little knowledge about the situation concerning clover fatigue in Norway. Clover is important in organic farming systems and problems with growing legumes will influence organic farming negatively. Both nematodes and fungi can cause clover fatigue. Plant parasitic nematodes were present in samples taken on organic farms in Norway 2011-2012. In 2014 clover plants and soil from 11 farms in Mid-Norway were analysed for both nematodes and fungi. All samples were infected with root rot Fusarium spp., mostly F. avenaceum. Plant parasitic nematodes were found in soil from all samples. Eight nematode groups were present. Spiral nematodes were the most common and abundant group; present on all the farms. No strong correlations were found between numbers of...

Einleitung    Das Pflanzenschutzmittel Biofa Cocana RF ist im schweizerischen Bio-Kernobstanbau das einzige zugelassene Mittel zur Bekämpfung der Regenfleckenkrankheit. Da es sich bei diesem Produkt um eine Kali-Seifenlösung handelt, besteht die Möglichkeit, dass es nach dessen Einsatz zu einer geschmacklichen Beeinträchtigung des Endproduktes Apfelsaft, bzw. Süssmost kommen könnte. Eine Untersuchung an der Hochschule Wädenswil mit Apfelsäften, denen Cocana zugesetzt wurde, kam zum Schluss, dass es einen Zusammenhang zwischen Kaliseife und Fremdgeschmack geben könnte.    Um abzuklären, ob unter Praxisbedingungen eine geschmackliche Unterscheidung zwischen Saft aus mit Biofa Cocana RF behandelten Früchten und solchem ohne Einsatz des Mittels er-kannt werden...

Überprüfung der Effektivität der maschinellen Ampferregulierung im Grünland mittels WUZI unter differenzierten Standortbedingungen
Provedor de dados: 21
Autores: Böhm, Herwart; Finze, Jana.
In den Jahren 2002 und 2003 wurde das selbstfahrende, von einem österreichischen Landwirt entwickelte Ampferbekämpfungsgerät WUZI am Standort Trenthorst (Institut für ökologischen Landbau der FAL) in Parzellenversuchen auf Grünland eingesetzt.  Der in diesen Versuchen erzielte Bekämpfungserfolg lag mit 57 % in 2002 bzw. 61 % in 2003 im Vergleich zum manuellem Ampferstechen (75 % in 2002 bzw. 60 % in 2003) auf fast vergleichbarem Niveau. Aufgrund dieser Ergebnisse wurde von Seiten der Beratung in Schleswig-Holstein, Niedersachsen und Hessen sowie den Demonstrationsbetrieben Ökologischer Landbau der Einsatz von WUZI auf Praxisbetrieben initiiert. Dies erlaubte gleichzeitig eine erweiterte, auf den Praxiseinsatz abgestimmte Bewertung des Gerätes unter...

Der Kleine Fruchtwickler Grapholita lobarzewskii Rag. hat sich zu einem wichtigen Schädling in der Bodenseeregion entwickelt. Um den betroffenen Betriebe Perspektiven aufzuzeigen, sollte untersucht werden, ob von den für den Öko-Obstbau zugelassenen potentiell gegen Wicklerarten wirksamen Insektiziden ein Effekt zu erwarten ist. Im Hinblick auf die aktuelle Situation ohne zugelassene Regulierungsmethode waren hier auch relativ geringe Wirkungsgrade von Interesse. Auf der Basis der hier erzielten Ergebnisse kann davon ausgegangen werden, daß mit Aufwandmengen an Quassiaextrakt von ungefähr 3 g/ha und mKh Quassin und einer Applikation im Normalfall Wirkungsgrade bis zu 60 % erzielt werden können.

Silomais im Ökolandbau: Einflüsse von Saattermin, Gülledüngung und Unkrautregulierung
Provedor de dados: 21
Autores: Schliesser, Ingeborg; Kolbe, Hartmut.
In zwei Berichten zu jeweils mehrjährigen Feldversuchen werden Einflüsse von Saattermin, Gülledüngung sowie Maßnahmen zur Unkrautregulierung auf Ertrag und Qualität von Silomais im ökologischen Landbau geprüft. Ein früher Saattermin erhöht die TM-Erträge. Alle geprüften Ausbringungsverfahren an Rindergülle (vor Saat breitflächig, Unterfußdüngung, 2-Blattstadium Injektion, 6-8-Blattstadium Schleppschlauch) sind praxistauglich und führen zu höheren Erträgen und besseren Qualitäten. Die Feldversuche zeigen, dass je nach vorhandener Technik verschiedene Strategien der Unkrautregulierung erfolgreich umgesetzt werden können.

Autores: Sieber, Karen; Forster, Georg M.; Diekmann, Kerstin; Sprengel, Michael; Kellermann, Adolf; Dehmer, Klaus-J.; Hammann, Thilo.
Die Ansprüche des ökologischen Landbaus an Kartoffelsorten unterscheiden sich zum Teil erheblich von denen des konventionellen Anbaus. Dies ist bedingt durch den alternativen Pflanzenschutz mit mechanischer Unkrautbekämpfung sowie durch eine in der Regel geringere Stickstoffversorgung der Pflanzen. Darum benötigt der ökologische Landbau spezielle Sorten, die neben den vom Verbraucher gewünschten Qualitätsmerkmalen auch eine hohe Widerstandsfähigkeit gegenüber Krankheiten und Schädlingen besitzen, durch schnelle Jugendentwicklung das Unkrautwachstum unterdrücken und eine hohe Nährstoffeffizienz aufweisen.  Um neue Zuchtstämme zu schaffen, in denen die im Biolandbau gewünschten Eigenschaften kombiniert vorliegen, etablierte das seit 2012 im „Bundesprogramm...

Hot water treatment of vegetable seed – an alternative seed treatment method to control seed borne pathogens in organic farming
Provedor de dados: 21
Autores: Nega, Eva; Ulrich, Roswitha; Werner, Sigrid; Jahn, Marga.
In future, conventionally produced seed will not be allowed for organic farming. Therefore, effective non-chemical methods are needed to control seed-borne diseases. Five important vegetable crops (carrot, cabbage, celery, parsley, lamb´s lettuce) and their most important seed-borne pathogens (Alternaria spp., Phoma spp., Septoria spp., Peronospora valerianellae, Xanthomonas spp.) have been investigated in laboratory, model and field trials.   Hot water treatments were made at temperatures of 40 °C and 50 to 55 °C for 10 to 30 minutes, in some cases to 60 minutes. In most cases, seed health tests were conducted according to ISTA guidelines. In case of seed infestation with Septoria species and P. valerianellae, the number of spores or oospores were counted...

Thinning of Elstar with lime sulfur in Nothern Germany
Provedor de dados: 21
Autores: Clever, Michael.
Thinning trials with lime sulphur in comparison to other products were carried out for 4 years in an ‘Elstar  orchard’ at the OVB Jork in Northern Germany. Beside the yield, the influence on fruit size, colour, russetting  and return bloom of treated trees were observed. Mechanic thinning was too strong and had other negative  effects. Thinning with potato meal and coconut soap had no effect. Organic oil (Telmion) reduced the yield  between 0 and 20%. Lime sulphur reduced the yield 0 – 40% in comparison of the concentration and the  number of applications. There were great fluctuations from year to year. In conclusion lime sulphur gives the  best results, but the variation from year to year is not acceptable for a practical advising in the northern area...

Moisture tempers impairment of adult Otiorhynchus sulcatus (Coleoptera: Curculionidae) climbing ability by fluoropolymer, talc dust, and lithium grease
Provedor de dados: 21
Autores: Bomford, Michael K.; Vernon, Robert S.
As part of a project to develop tools for the physical exclusion of flightless root weevils, adult black vine weevils (BVW), Otiorhynchus sulcatus (F.), were placed in open enclosures with smooth walls of glass, plastic or aluminum to test their ability to escape by climbing. Enclosure walls were left untreated or were treated with substances known to reduce insect climbing ability: fluoropolymer, powdered talc and lithium grease. No BVW escapes were observed under dry conditions, but all treatments allowed some escapes under wet conditions, suggesting that moisture helps BVW adults scale treated surfaces. The results help explain the ability of root weevils to overcome physical barriers under field conditions.

Producing organic wheat with high grain protein content: the  significance of intercropping and the need for diagnostic tools
Provedor de dados: 21
Autores: Naudin, Christophe; Corre-Hellou, Guénaëlle.
Grain quality of wheat is one of the major concerns of organic farming production. Cereal-legume intercropping may be of significance in this regard as it enhances the yield productivity and the grain protein content (GPC) of the intercropped wheat. However, fitted tools are needed for the diagnosis and management of such interspecific canopies. Our main objectives were i) to analyse the effect of intercropping and N-management on organic farming performances and ii) to analyse the relationships between N-status indicators and GPC of intercropped wheat. These objectives were assessed in winter pea–wheat intercrops in 2007 and 2009 in western France. Our study confirmed the significance of intercropping in the production of wheat with high GPC. We showed...

Kobber er tillatt som plantevernmiddel i økologisk landbruk i EU-forordningen, men er ikke tillatt brukt i økologisk landbruk i Norge. I forbindelse med implementering av ny forordning skal norske myndigheter utarbeide ny forskrift om økologisk produksjon. Myndighetene må avgjøre om de ønsker å videreføre dette unntaket. Utredningen vil gi Regelverksutvalget for økologisk produksjon (RVU) et grunnlag for å gi innspill om bruk av kobber til Mattilsynet.     Bruk av kobber har god effekt mot flere viktige sopp- og bakteriesykdommer i frukt, bær, vindruer og potet. Kobber virker forebyggende og er ansett som en viktig resistensbryter.

Assessing climate change impacts on fruit plant and pest phenology and their synchrony: the case of apple and codling moth
Provedor de dados: 21
Autores: Felber, Raphael; Stöckli, Sibylle; Calanca, Pierluigi.
Temperature is a main climatic driver of plant phenology and the dominant abiotic factor directly affecting insect pests. Global warming is therefore expected to accelerate the development of plants and insects alike. In the case of multivoltine pest species, it was shown that higher temperatures lead to the appearance of additional generations toward the end of the warm season (Stöckli et al., 2012), which also has implications for pest management. The same effect was shown for the timing of flowering termination of apple trees (Stöckli and Samietz, 2015), the time when a pest can attack a fruit. In practice, however, much would depend on whether plant and pest phenology remain synchronized or not.    Focusing on Switzerland, in this contribution we...

Regulierung von Phytoplasmosen im ökologischen Weinbau - Risikoanalyse und Lösungsansätze
Provedor de dados: 21
Autores: Maixner, Michael; Langer, Markus.
Die Schwarzholzkrankheit, eine Phytoplasmose, ist ein zunehmendes Problem besonders im Steillagenweinbau. Der Infektionsdruck wird bestimmt durch das Vorhandensein krautiger Wirtspflanzen sowohl der Phytoplasmen als auch der krankheitsübertragenden Zikade Hyalesthes obsoletus, deren Larven an den Wurzeln dieser Pflanzen leben. Art und Intensität der Bodenbewirtschaftung und -begrünung beeinflussen daher das Risiko durch die Schwarzholzkrankheit. Ziel der Untersuchung war es, Informationen über das Infektionsrisiko durch Phytoplasmosen in ökologisch bewirtschafteten Weinbergssteillagen zu erarbeiten und Ansätze für Regulationsstrategien zu entwickeln.

In Central Europe low temperature is limiting soybean growth and biological nitrogen fixation (BNF). The BNF efficiency was shown to increase with bradyrhizobia strains selected for their cold tolerance. Significant bradyrhizobia x soybean variety interactions were reported. Co-inoculation with arbuscular mycorrhiza fungi (AMF) may promote bradyrhizobia and improve plant phosphorus uptake. The aim of this study is to identify (i) bradyrhizobia showing improved nodulation under cool conditions, (ii) bradyrhizobia x soybean variety and (iii) bradyrhizobia x AMF interactions. In 2011 twelve bradyrhizobia inoculants were tested with three soybean (Glycine max [L.]) varieties under three temperature regimes (14/10°C, 16/12°C, 22/20 °C) in a pot trial. In 2012...

Brown plant hopper showed me the way into organic farming. In 2001, I started my practice with logic of legumes just to cut down the 45 percent expenses of my paddy on fertilizers, pesticides and herbicides.  Later as I realized each and every plant carries it’s own nutrients, medicinal values and characters.  Plants like millets, oil seeds, spices, di-cots, monocots and weeds all being used as a green manure.  For all my agriculture problems and crop demands, I look for the answers only through green manures and found almost.  Past from 15 years, I still grow in 15 acres with over 45 percent less inputs, 20-25 quintals of paddy yield per acre and my profit has grown 10 times in last 10 years.

Entwicklung nachhaltiger Bekämpfungsstrategien für Feuerbrand
Provedor de dados: 21
Feuerbrand ist im Moment die grösste Bedrohung für den Kernobstbau in der Schweiz. Die Entwicklung von Bekämpfungsmöglichkeiten, die mit der aktuellen Strategie der Verhinderung sowie mit dem bestehenden Prognose- und Warndienst kombiniert werden können, ist eine Priorität für den schweizerischen Obstbau. Bisher konnten in der Schweiz nur begrenzte Studien über das Potenzial von Bekämpfungspräparaten durchgeführt werden. Ein umfassendes Forschungsprogramm muss, neben dem Screening von Antagonisten, Pflanzenextrakten und chemisch-synthetischen Pflanzenschutzmitteln (PSM) auch Mechanismen der Wirkung (und der Nicht- Wirkung) solcher Produkte aufklären und Wechselwirkungen zwischen den verschiedenen Bekämpfungsmöglichkeiten (inkl.

Histopathological study of the effect of post leaf fall application of urea on saprotrophic development of the cherry leaf spot pathogen, Blumeriella jaapii
Provedor de dados: 21
Autores: Bengtsson, M.; Hockenhull, J.; Neergaard, E.de.
The formation and development of over-wintering structures of the leaf spot pathogen Blumeriella jaapii in urea treated leaves of sour cherry (Prunus cerasus) during autumn, early winter and in May were studied histopathologically and compared to leaves treated with water. Resin embedding using glycol methacrylate (GMA) and subsequent staining of sections with Amido Black were used. Macroscopic and microscopic studies of B. jaapii in water treated leaves showed that the development of the over-wintering stages begins randomly in individual leaf spots both pre and early post leaf fall. Saprotrophic growth and stroma formation in leaves is completed between six to eight weeks after leaf fall. During the following spring stromata normally develop apothecia or...

Non-inverting soil tillage as a means of optimising soil tilth
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.; Rasmussen, K.J.
A field experiment was initiated in 1997 with non-inverting soil tillage compared to conventional tillage with annual mouldboard ploughing to either 20 cm depth (CT) or 10 cm depth (RCT). The new system included a non-inverting mechanical loosening of the soil to approximately 35 cm depth combined with a shallow cultivation of the top 5 cm soil by either a rotovator (NIT) or an S-tine harrow (RNIT). The experiment was located on a sandy loam at the organic farmed Rugballegård Experimental Station. A plough pan at 20-35 cm depth was identified by cone penetration measurements. The non-inverting tillage system succeeded in breaking up the plough pan, which reduced the cone index from approximately 1.8 MPa in the CT and RCT treatments to 0.6 MPa in the NIT...

Backweizen ist eines der wichtigsten Produkte des ökologischen Landbaus, dessen Erzeugung in Hinblick auf die erforderliche Qualität leider großen Schwankungen und Risiken unterworfen ist. Zur Synthese von Eiweiß, im  Falle der Backqualität von Korneiweiß, ist eine genügende N-Nachlieferung aus dem Boden in späten Wachstumsstadien nach der Blüte notwendig. Hier besteht im ökologischen Landbau in der Regel ein deutlicher Mangel. Zum einen sind die Vorräte an Nmin im Boden im Mai ausgeschöpft, sie müssten durch neue Quellen, wie etwa einer späten Güllegabe, wieder aufgefüllt werden. Zum anderen neigen Bestände hochleistungsfähiger Weizensorten dazu, den zum Schossen verfügbaren N zur Bildung von Ertragsanlagen auszuplündern, so dass bei begrenzten Vorräten...

Strategies to reduce mycotoxin and fungal alkaloid contamination in organic and conventional cereal production systems
Provedor de dados: 21
Autores: Köpke, U.; Thiel, B.; Elmholt, S.
Mycotoxins are toxic metabolites formed by specific fungi that grow on living plants and their residues under favourable conditions. They are undesirable ingredients of food and feed. Risks are also posed by the spores and toxin-contaminated raised dusts. Contamination by mycotoxins is a severe problem in food security. More than 300 species of fungi with the ability to form mycotoxins have been identified. More than 400 metabolites are assigned to the group of mycotoxins. Fortunately, only about 20 mycotoxins produced by five genera of fungi (Fusarium, Penicillium, Claviceps, Alternaria and Aspergillus) are found regularly or periodically in food and feed at levels which might have an impact on human and animal health (Gareis, 1999a).

Alternative Wachstumsregulierung von Pflanzen mittels gesteuerter Vibrationstechnik als Ersatz chemischer Hemmstoffe
Provedor de dados: 21
Synthetische Wachstumshemmstoffe werden in fast allen Produktionsgartenbaubetrieben angewendet. Schwerpunkt ist dabei die Hemmung des Längenwachstums, Förderung der Verzweigung sowie die Blühinduktion. Alternativen zur Wachstumsregulierung sind u.a. eine trockene Kulturführung, Diff und Cool Morning sowie eine Kultivierung unter zeitweisem Stickstoffentzug. Alle diese kulturtechnischen Möglichkeiten werden zum großen Teil umgesetzt, führen aber häufig zu nicht zufriedenstellenden Ergebnissen, sodass trotzdessen zusätzlich chemische Wachstumshemmer eingesetzt werden müssen. Die Langzeitwirkung von chemischen Wachstumsregulatoren auf die Ökosysteme ist jedoch nur unzureichend bekannt.  Mit Hilfe des beantragten Projektes soll eine neue, innovative,...

Neues Granulovirus Isolat: Bekämpfung von resistenten Apfelwicklerpopulationen möglich?
Provedor de dados: 21
Autores: Jehle, Johannes A.; Eberle, Karolin E.
Das Apfelwickler-Granulovirus (CpGV) wird seit vielen Jahren mit großem Erfolg im biologischen und integrierten Apfelanbau eingesetzt. Seit zwei Jahren gibt es vereinzelte Beobachtungen von Apfelwicklerpopulationen, die eine stark reduzierte Empfindlichkeit gegenüber Granulosevirus-Präparaten aufweisen. Mit neuen Apfelwickler-Granulovirus-Isolaten, die in der Lage sind, diese Resistenz gegen das Virus zu brechen, besteht die begründete Chance eine weitere Etablierung dieser resistenten Populationen zu verhindern und einen ausreichenden Bekämpfung in den betroffenen Anlage zu sichern. Am DLR Rheinpfalz wurde jetzt erstmals ein neues Apfelwickler-Granulovirus-Isolat identifiziert, das im Labortest gegenüber resistenten Apfelwicklerpopulationen eine ähnlich...

Provedor de dados: 21
Autores: Müller, Dr. Karl-Josef.
Fifty-five spring barley varieties from the German official varieties list were tested for their susceptibility to loose smut (Ustilago nuda) and covered smut (Ustilago hordei) under a simulation of natural infection conditions. For loose smut infection cv. ‘Lawina’ with about 5 % infected plants was used as spreader. In the trial with covered smut 1kg of seeds were shaken with 1g of spores to contaminate the surface of barley seeds before sowing. Only ‘Steffi’ stayed absolutely free from loose smut during two infection cycles at two locations. With an average of 12.6 % plants with loose smut ‘Danuta’ was the most susceptible. Most susceptible to covered smut were ‘Tunika’ with 13.2 % and hulless ‘Taiga’ with 15 % infected plants. Thirteen varieties...

Teilversuch 1:   Sortenvergleichsanbau mit verschiedenen z.T. ökologisch vermehrten Möhrensorten. Teil I - Standort Sudwalde  Auch im zweiten Versuchsjahr zeigten sich Sortenunterschiede in der Anfälligkeit von Industriemöhrensorten gegen Möhrenschwärze (Alternaria dauci) auf dem Feld. Bei den im zweiten Jahr geprüften Sorten bestätigten sich die im Vorjahr gefundenen Tendenzen hinsichtlich der Anfälligkeiten. Ein Zusammenhang mit der – im Jahr 2005 allerdings geringen – Vorbelastung des Saatgutes mit dem Erreger konnte nur insofern gefunden werden, dass an der Sorte mit der höchsten Saatgutbelastung (Nectar) auch als erstes der stärkste Befall am Laub gefunden werden konnte. Bei der weiteren Vermehrung der Alternaria überwog dann der Einfluss der...

SENSORY AND HEALTH-RELATED FRUIT QUALITY OF ORGANIC APPLES. A COMPARATIVE FIELD STUDY OVER THREE YEARS USING CONVENTIONAL AND HOLISTIC METHODS TO ASSESS FRUIT QUALITY
Provedor de dados: 21
Autores: Weibel, Franco P.; Treutter, Dieter; Häseli, Andi; Graf, Ursula.
In a 3 years lasting field study with the ‘Golden Delicious’ cultivar, we compared fruits of 5  pairs of organic/integrated fruit farms. The orchards were similar in microclimate, soil conditions and  planting system. To assess inner fruit quality we investigated at the beginning and at the end of cold  storage: (i) standard parameters (firmness, sugar, malic acid., mineral content); (ii) sensorial quality  by panel tests; (iii) health related components (23 phenolic compounds, nutritional fibres; vitamins);  and (v) fruit «vitality quality» by holistic approaches (crystallisation in copper chloride, self degradation  tests, feeding preference tests with laboratory rats).  The most significant differences were found in year one of the study, and were by...

Utvikling av ny insektfelle for jordbærsnutebillen
Provedor de dados: 21
Autores: Wibe, Atle; Røyset, Arne; Ebbesvik, Martha.
Mange bær, frukt- og grønnsaksfelt kan bli påført betydelig skade av ulike insekter. For å hindre slike skader benyttes det i konvensjonelle produksjonssystemer betydelige mengder insekticider. Imidlertid er det bekymringsfullt hvilke negative virkninger slike stoffer kan ha på miljøet og folkehelsa. Derfor vil kontrollstrategier ved bruk av insektfeller være mer bærekraftig. Fellene som blir benyttet til å fange jordbærsnutebiller ser ut til å ha en begrenset effekt. Dette prosjektet har derfor som mål å utvikle en mer effektiv insektfelle for å utvikle ny strategi i kontroll av denne skadegjøreren. Anatomisk viser jordbærsnutebillen seg å være lik andre biller med å ha klør og børstehår på beina for å få feste til underlaget. Ved testing av ni ulike...

Thresholds for Net Blotch Infestation in Organic Barley Seed Production
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.; Hansen, Henrik J.
Net blotch-infested seeds can be as important as initial inoculum source for net blotch epidemics as other inoculum sources such as infected straw. Our results underline the importance of varietal resistance for seed health. Employing resistant varieties results in low net blotch severity levels in the field which in turn reduces the risk of seed infestation. The results give reason to assume that the present threshold recommendations for seed born barley net blotch could be raised for normal  growing conditions and/or for varieties having a reasonable level of net blotch resistance.   Supplemental results are expected from ongoing field trials and more detailed analyses will follow to improve our understanding of quantitative relationships among...

Beetle eater beheerst de aspergekever bij de oogst van groene asperges in 2010
Provedor de dados: 21
Autores: van den Broek, R.; Rovers, J.; Gruppen, R.; Gubbels, W.
In Canada is een grote stofzuiger die voor of achter een tractor bevestigd kan worden “Beetle Eater”  genaamd, gebruikt ter bestrijding van de coloradokever in aardappelen. Biologische telers hebben zo’n  apparaat gekocht om hem in te zetten ter bestrijding van de wortelvlieg in peen. De resultaten vielen tegen en het apparaat is na twee jaar experimenteren niet meer gebruikt.     In 2010 is de machine getest in groene asperges tegen de aspergekever op een gangbaar bedrijf in Noord - Brabant. Omdat groene asperges bij gunstige weersomstandigheden dagelijks geoogst worden, is het lastig om tegen dit insect gewasbeschermingsmiddelen in te zetten vanwege de veiligheidstermijn. Door de Beetle eater 1 of 2 keer (direct na elkaar) in te zetten worden de...

How to optimize fruit and berry cultivar selection for organic farmers ? A comparison of European approaches.

Most of the currently grown commercial fruit cultivars remain unsuitable to low-input or sustainable organic farming systems. The major reason is that  they have been developed and selected under high input cultivation, and without sufficient attention to susceptibility to pests and diseases. Some of these cultivars are nevertheless marketed as resistant because they carry genetic markers for major resistance genes but these are unfortunately prone to break-down (most of apple resistant cultivars relay only on the Vf). As a result, new fruit cultivars tend to reveal unexpected and often undesirable traits when grown in commercial organic orchards, and thus fail to bring about the much needed expansion in organic production and market availability. However,...

MANAGEMENT OF STRAWBERRY BLOSSOM WEEVIL AND EUROPEAN TARNISHED PLANT BUG IN ORGANIC STRAWBERRY AND RASPBERRY USING SEMIOCHEMICAL TRAPS “Softpest Multitrap”
Provedor de dados: 21
Autores: Wibe, Atle; Cross, Jerry; Borg-Karlson, Anna-Karin; Hall, David; Sigsgaard, Lene; Baroffio, Catherine; Ralle, Baiba; Fountain, Michelle.
Many European growers of organic strawberry and raspberry have large losses in yield (sometimes &gt;80%) and reduced quality of their products because of insect damage. Among the major threats are the strawberry blossom weevil (Anthonomus rubi Herbst), the European tarnished plant bug (Lygus rugulipennis Popp.) and the raspberry beetle (Byturus tomentosus De Geer). In organic soft fruit production there are no effective control measures for these pest insects.  For many insects species pheromones and host plant volatiles are of major importance in mate finding and location of host plants for mating, feeding and oviposition. Thus, there is potential for using these insect-insect and/or insect-host plant interactions to develop new strategies and effective...

Managment of Crops to Prevent Pest Outbreaks
Provedor de dados: 21
Autores: Daniel, Claudia; Barloggio, Guendalina; Stoeckli, Sibylle; Luka, Henryk; Niggli, Urs.
Organic farmers face the same potentially severe pest problems as their colleagues in integrated pest management (IPM) and conventional farming systems. However, approaches to manage the pest insects are different because the aim of organic farming is a holistic system perspective rather than simple reductionist control approaches. Organic cropping systems are designed to prevent damaging levels of pests, thus minimizing the need for direct and curative pest control (Peacock and Norton, 1990). Within the following chapter, we will briefly explain the standards for organic farming, which also set the framework for pest control. We present a conceptual model for pest control in organic farming and describe the influence of functional agro-biodiversity and...

The use of kaolin to control Ceratitis capitata in organic citrus groves.
Provedor de dados: 21
Autores: Lo Verde, Gabriella; Caleca, Virgilio; Lo Verde, Valentina.
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera Tephritidae), is the key pest in some organically managed citrus orchards in Sicily. The effectiveness of processed kaolin (Surround WP) for control of C. capitata damage was tested in field trials carried out in 2003-2004 on two early ripening citrus species: satsuma (Citrus unshiu Markow.) and clementine (Citrus clementina Hort. ex Tan.). Although the number of males captured in trimedlure baited traps was high in both years and in both orchards, the percentage of damaged fruit varied greatly from almost 0% (satsuma 2003) to more than 60% (clementine, both years). Nevertheless, the application of processed kaolin significantly reduced damage caused by C. capitata on both citrus spe-...

Functional biodiversity can be enhanced by in settling, in the crops surroundings, specific vegetal species that will increase the occurrence of beneficial insects, by providing shelters, and alternative preys. This technique, also called biological control by habitat manipulation, was adapted in Southern France to control spider mites (Tetranychus urticae), and white flies (Trialeurodes vaporariorum and Bemisia tabaci) using two predatory mirid bugs Macrolophus pygmaeus and Dicyphus errans.  Trials started in 2007, with a first step consisting in selecting adapted host-plants for these two mirids. 22 species of host-plants have been sown in strips between greenhouses at the experimental station of GRAB (Avignon – Provence).

Autores: Walther, Bernd; Pelz, Hans-Joachim.
Wühlmausschäden gehören zu den am schwierigsten lösbaren Pflanzenschutzproblemen im ökologischen Obstbau. Nach einer Umfrage waren im Jahr 2002 79 % der deutschen Apfelanbaubetriebe von solchen Schäden betroffen. Auf 80 % der Flächen war die Schermaus (A. terrestris) der Hauptschadensverursacher. 61 % der Obstbauern sahen einen hohen Bedarf an der Entwicklung neuer Präventiv- und Bekämpfungsmaßnahmen.   Um die Einwanderung von Wühlmäusen in Obstbauflächen zu verhindern, wurde ein mechanisches Barrieresystem entwickelt und an je einem Standort in Baden-Württemberg und Rheinland-Pfalz getestet.

Sixty spring barley varieties were tested at two locations for susceptibility to barley leaf stripe after natural infection at two locations with one infected spreader line (LINZ 358150). The genetic resources VADA, BETZES and RICARDO and cultivars BAC-CARA and PEGGY remained below 0.1% infection. Another eleven varieties stayed below a poor susceptibility of 1% infection, but 13 varieties showed more than 5% infected plants. Analysis of variance brought no difference for the locations to test the infestation, but a strong influence of the location, where the infection during flowering took place. It gives reason not to multiply susceptible varieties under organic farming at barley leaf stripe threatened locations. Breeding of spring barley should be done...

Smaktestning av skorvresistenta äpplesorter
Provedor de dados: 21
Det är av flera skäl önskvärt att öka den ekologiska produktionen av äpplen. Regeringens mål är att tjugo procent av jordbruksarealen ska brukas ekologiskt år 2005. De äpplesorter som används i de konventionella odlingarna idag är framtagna under en tid då bekämpningsmedel löste alla problem med skadegörare. Restriktioner har dock införts och flera bekämpningsmedel är inte längre tillåtna. De flesta befintliga äpplesorterna går överhuvudtaget inte att odla utan bekämpning med fungicider. Det är därför mycket viktigt att hitta nya sorter som förutom att de är resistenta mot skorv också smakar bra och accepteras av konsumenten.

Autores: Canali , S.
From 2011 to 2015, in the frame of InterVeg project, four field experiments were carried out in Italy, Slovenia, Germany and Denmark in order to study the effect of the living mulch introduction.   In 4 different European climatic areas, ecological services have been exploited by use of living mulches in intercropping systems for production of vegetable crops.     What is Living Mulch?  Living Mulch can be defined as a cover crop intercropped with a main crop: the practice of growing two (or more) crops simultaneously in the same area offers a great potential to enhance the ecological support functions of agro-ecosystems at field and farm scale, thus increasing crop production sustainability. Moreover, it has been demonstrated that intercropping can...

Tolerance to weed harrowing in spring barley genotypes
Provedor de dados: 21
Autores: Hansen, Preben Klarskov.
Controlling weeds in spring cereals grown under organic conditions is mostly done by post emergence weed harrowing, where spring tines of the weed harrow control weeds by uprooting and/or covering small weeds plants with soil. In situations with relatively large weed plants and relatively small crop plants, there are increased risks for crop damages by soil coverage or other mechanical damages of the crop leaves. These damages are increasing with increasing weed control intensity, and are resulting in reduced crop growth immediately after weed harrowing. There are risks that the reduced growth reduces final crop yield too.  However, there is some evidence that there are varietal differences in the tolerance to weed harrowing.    The aim of this study was...

Management Practices for Control of European Wireworms in Canada
Provedor de dados: 21
Autores: MacKenzie, Joanna; Nelson, Jody; Hammermeister, Andy.
Significant losses in crop yield, quality and marketability have been attributed to wireworms, a pest of growing concern and widening distribution in Nova Scotia and across Canada.  While the Maritime Provinces harbour indigenous wireworm species, three species introduced to North America from European ship ballast cause the lion's share of damage.    The destructive larvae of these three species, Agriotes lineatus, A. obscurus, and A. sputator, persist in the soil for several years, feeding on the roots of host plants and causing significant reductions in the yield and quality of economically important crops. Root crops such as potatoes and carrots are particularly susceptible because damage (holes produced by feeding larvae) to the new tubers and carrots...

Diese Unterschiede beziehen sich sowohl auf die im Anbau befindlichen Ölfruchtarten und deren jeweilige Bedeutung als auch auf die Anforderungen an die Kulturführung und die Vermarktungs- und Nachfragesituation. Die Anbaubedeutung von Ölsaaten im Ökologischen Landbau ist bislang immer noch gering.

Genetic variation and pathogenicity of Phytophthora infestans isolates collected from organic potato crops of the susceptible cv. Bintje and the moderately resistant cv. Santé were assessed in France, Norway, and the United Kingdom in 2001 and in Switzerland in 2001 and 2002. Population structures differed considerably between the four P. infestans populations. Those from France, Switzerland and the UK were mainly clonal populations showing restricted levels of genetic diversity, whilst those from Norway were mixed A1 and A2 mating type populations with high levels of genetic diversity, suggesting periodical sexual reproduction. Isolates collected from cv. Bintje were on average more aggressive than or comparable to isolates from cv. Santé. Race complexity...

Heterogene Weizenpopulationen als Alternative zu kommerziellen Sorten unter ökologischem Management
Provedor de dados: 21
Autores: Weedon, Odette; Schmidt, Jan-Henrik; Finckh, Maria Renate.
Interest in heterogeneous crop populations is growing within both the scientific community, as well as with organic farmers. In order to ensure widespread acceptance amongst farmers, agronomic testing of currently available composite cross populations (CCPs) under organic management is necessary. Eleven CCPs were compared to five commercially grown varieties in a two-year field experiment under organic management (2016/17 and 2017/18). The results over the two experimental years indicate that CCPs are a viable and interesting alternative to commercial varieties within organic farming systems.

Effect of Organic Based Soil Fertility Management Strategies on Soil Nutrient Status And Marketable Quality Of Kale (Brassica Oleracea Var. Acephala) In Kabete, Kenya
Provedor de dados: 21
Autores: Genga, Quintar; Onwonga, Richard; Kimenju, Wangai; Jensen, Henning Høgh.
Demand for uncontaminated and safe agricultural products in Kenya for the last two decades has created a major shift from the use of conventional farming practices to organic based techniques. However, there remains a challenge of poor quality and yield of vegetables. This study aimed to enhance the quality and yield of kale ((Brassica oleracea var. acephala) in Kabete - Kenya, through use of organic inputs and integration of chickpea (Cicer arietinum) either as an intercrop or in rotation with kale. The experimental layout was a randomized complete block design with a split plot arrangement. The main plots were cropping systems; crop rotation (Chickpea – Kale), monocropping (sole Kale) and intercropping (chickpea/Kale). The split plots were organic inputs...

SMART PROJECT : Agroforestry systems using fruit trees and vegetables in France
Provedor de dados: 21
Autores: Warlop, Francois.
Agroforestry systems mixing fruit trees and annual crops are very well developed and studied in tropical countries, but they have been forgotten or neglected during the last 40 years in France and Europe. Current trends and challenges in agriculture (land access, periurban agricultural forms, inputs reduction through functional biodiversity and crop diversification) lead small farmers in France to combine annual plants and fruits with the aim to increase their field performance on a multifunctional basis. The SMART project identified about 150 projects (mostly all being organic) and further explored 40 of them, to better understand organization and adoption criteria.

Fire blight control in organic fruit growing – systematic investigation of the mode of action of potential control agents
Provedor de dados: 21
Autores: Kunz, Stefan.
Effective control agents are needed to prevent blossom infections by the fire blight pathogen Erwinia amylovora in organic fruit growing. In this study 18 preparations of potential control agents were compared for their efficiency against E. amylovora. In shaken cultures twelve control agents inhibited the growth of E. amylovora completely. In this system different mechanisms of action were found. Six control agents shifted the pH of the cultures to values not suitable for bacterial growth (&lt;5 or &gt;8). Three agents act by copper, a known bactericide. The control agent Elot-Vis has high ethanol content, which was responsible for the high efficiency in vitro. On detached apple blossoms only four control agents led to a symptom reduction of more than...

Threats of emerging pests due to a warming climate in Finland
Provedor de dados: 21
Autores: Tuovinen, Tuomo; Lindqvist, Isa.
The total strawberry acreage in Finland (3225 ha, 2008) is almost entirely attributed to outdoor cultivation. The prevailing weather directly influences both the quality and quantity of the yield. An increasing demand for quality berries forces growers to consider cultivation in polythene tunnels. In addition to cultivation changes, new plant protection challenges are also expected to arise as a result of a warming climate.

Prüfung neuer pilzwiderstandsfähiger Rotweinrebsorten auf ihre Anbaueignung in Franken
Provedor de dados: 21
Autores: Schwab, Arnold; Knott, Reiner.
Five new fungus-tolerant grape varieties were tested from 2005 to 2010 in comparison to Merlot in Franconia/Germany. Crossings with Cabernet Sauvignon showed different ripening behavior, and aroma expression. Cabernet Carbon presented a full-bodied wine, whereas Cabernet Coral ranged sensorically near his cross parent Cabernet Sauvignon. Reberger as a very early ripening variety reached often plumy notes. All 5 varieties are not totally fungus resistant and need some plant protection depending on the yearly infection conditions. In specific years the tested Cabernet crossings had problems with stem dieback and bunch rot. Cabernet Carol and Cabernet Cortis reached the best results in relation to Merlot.

EFFECTS OF PLOUGHING IN AND REMOVING LITTER LEAVES FROM THE GROUND ON THE DEVELOPMENT OF SCAB EPIDEMICS IN AN ORGANIC APPLE ORCHARD
Provedor de dados: 21
Autores: GOMEZ, Christelle; BRUN, Laurent; CHAUFFOUR, Dominique; DE LE VALLEE, Damien.
Ascospores produced on scabbed leaves in the leaf litter are the main source of scab primary inoculum, causing scab infections in apple orchards. The purpose of this experiment, carried out during two years in a commercial organic orchard, was to assess the effect of combining leaf removal from the alleys and leaf ploughing in within the row, on scab primary inoculum and therefore on scab epidemics. Scab lesions were monitored on leaves and fruits by assessing scab incidence and scab severity. In 2003, scab severity was monitored at different distances from the unremoved leaf area, in order to estimate ascospore spreading. At fruit harvest, along two years with low (2003) and high (2004) levels of scab development, the leaf litter ploughing in / removal...

Bestimmung der optimalen Aussaat- und Umbruchtermine einer überwinternden Leguminosen-Gründüngung für die nachhaltige Bekämpfung pflanzenparasitärer Nematoden im ökologischen Gemüsebau
Provedor de dados: 21
Autores: Hallmann, Johannes; Fittje, Susanne; Warnecke, Hermann; Buck, Holger; Rau, Florian; Krüssel, Stefan.
Pflanzenparasitäre Nematoden können in engen Gemüse-Fruchtfolgen erhebliche wirtschaftliche Schäden verursachen. Zu den Hauptschaderregern gehören Meloidogyne hapla und Pratylenchus spp. Gefördert werden diese Nematoden insbesondere durch den Anbau von Leguminosen. Im vorliegenden Forschungsvorhaben wurde untersucht, wie Leguminosen anzubauen sind, um einerseits Stickstoff zu fixieren, andererseits aber eine Vermehrung von M. hapla zu verhindern. Eine Lösung könnte der Anbau als überwinternde Leguminosen-Gründüngung darstellen. In dreijährigen Feldversuchen konnte gezeigt werden, dass es bei Aussaat der Leguminosen-Gründüngung ab Ende August nicht mehr zu einer Nematodenvermehrung vor Beginn der Winterruhe kommt. Im folgenden Frühjahr muss dann erst wieder...

The effect of irrigation method on the quality and shelf-life of strawberry fruit in organic production
Provedor de dados: 21
Autores: Parikka, Päivi.
The irrigation method did not affect either the shelf-life or the quality of fruit. In organic strawberry production grey mould is a major problem. Strawberry varieties differ from each other in disease susceptibility and the quality and shelf-life of the fruit is affected more by their properties and weather conditions than by the irrigation method.

Genetic characterization of Apulian wild population of the parasitoid Psyttalia (Opius) concolor (Szepligeti) for biological control of Bactrocera oleae (Gmelin).
Provedor de dados: 21
Autores: KARAM, Nisrine.
Given the morphological similarity between the released Psyttalia (Opius) concolor and the wild Apulian ones, the biological control program against the olive fruit fly Bactrocera oleae is faced with problem of evaluating the efficacy of the release using the released reared endoparasitoid. A DNA molecular technique, the Random Amplified Polymorphic DNA (RAPD) was used to define eventual molecular markers and to assess the genetic variability between seven wild Apulian populations and one reared strain of P. concolor. A RAPD approach highlights a high genetic similarity among the populations from Puglia, suggesting a common evolutionary history. It also revealed a high genetic homogeneity between the reared and the Apulian samples, ruling out the...

Control of venturia inaequalis: substitutes for and reduced use of copper
Provedor de dados: 21
Autores: Palm, Gerd; Klopp, Karsten; Kruse, Petra.
In 2001 eleven different apple scab control strategies with reduced copper use and copper substitutes were tested on an organic apple orchard near Hamburg, Germany. The strategies were tested on a six year old "Elstar" plantation. Among the different fungicides were copper sulphate, copper hydroxide, lime sulphur, sulphur, bacillus subtilis and "Biofa-Algenextrakt".  The results show that fruit scab as well as leave scab can be fairly well controlled by a lime sulphur strategy and the copper hydroxid strategies. Bad results were produced with the different copper sulphate strategies and bacillus subtilis, insufficient results with the sulphur strategies.

Efficacy of Armicarb (potassium bicarbonate) against scab and sooty blotch on apples.
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Schärer, Hansjakob; Refardt, Matthias.
A novel formulation of potassium bicarbon-ate (Armicarb) was evaluated in 2004 and 2005 as agent against apple scab and sooty blotch in several field trials. Armicarb controlled scab equally well as the reference treatments sulphur and copper. Armi-carb showed also excellent activity against sooty blotch. However, potential side-effects such as lenti-cell spot development need further investigation. At present, potassium bicarbonate is considered by the Swiss registration authorities as non-toxic to humans and in consequence, no residue levels have been specified. Armicarb has very interesting properties as a plant protection agent and its composition and risk profile are expected to fulfil the IFOAM standards for acceptance of novel plant protection...

Population structure of Pyrenophora teres, the causal agent of net blotch of barley
Provedor de dados: 21
Autores: Serenius, Marjo.
Pyrenophora teres populations are differentiated at sevaral levels. Human assistance in dispersal of P. teres on infected barley seed might decrease the differentiation, which would increase plant protection problems caused by this pathogen. P. teres is capable of sexual reproduction in several areas. Good agricultural practices, including crop rotation and use of healthy seed, are recommended.

Crop rotation and its ability to suppress perennial weeds
Provedor de dados: 21
Autores: Askegaard, Margrethe.
The appropriate combination of crops and green manures prevents spread of perennial weeds and increases crop yields and quality. Weed-suppressing crop rotations are absolutely essential for sustainable organic arable farming.  Practical recommendation  Basic rules  • Implement green manures, such as clover or lucerne, in at least 20 % of the rotation.  • Do not grow more than 50 % of cereals with low weed competitiveness in the rotation. Do not cultivate such crops for more than 2 consecutive years.  • In fields with prevalent high weed pressure cultivate only crops with high weed competitiveness.   Points to consider in case of high weed pressure:  • Do not grow grain legumes where perennial weeds are a problem. Late harvest in combination with loose...

Biological control of leatherjackets using insect pathogens OF0116T
Provedor de dados: 21
Autores: Chandler, David.
Leatherjackets (Tipula spp.; larvae of crane flies) are significant pests affecting the organic farming sector. Effective non-chemical methods of protecting organic crops from leatherjackets have not yet been developed, although insect pathogens are a promising method for biological control of these pests. This study will aim to identify and evaluate fungi, nematodes and the bacterium Bacillus thuringiensis for their effectiveness as control agents. The pathogens will be sourced from the HRI resource collection. Selected isolates of pathogens with known activity to dipteran pests will be screened in bioassays against laboratory-reared leatherjackets. Virulent isolates will be examined in detail both in laboratory experiments and glasshouse trials on a...

Pollinering och kontroll av skadegörare i ekologiska klöverfröodlingar - effekter av diversifiering på fält- och landskapsnivå
Provedor de dados: 21
Tillgång till ekologiskt odlat utsäde av klöver utgör en flaskhals för ekologisk odling. Otillräcklig pollinering och angrepp av insektsskadegörare kan begränsa skörden. Genom att förändra odlingstekniken i det odlade fältet kan man förbättra viktiga ekosystemtjänster såsom pollinering och biologisk kontroll. En uthållig och stabil förvaltning av ekosystemtjänster kräver dock även ett landskapsperspektiv. Projektet kommer, för att säkra en hög och stabil skörd av ekologiskt odlad klöverfrö, att utveckla odlings- och förvaltningsstrategier på fält- och landskapsnivå. På fältnivå undersöker vi om pollinationen förbättras när de pollinerande insekterna tillförs en tidigt blommande resurs till den sent blommande klövern. Vi utför dessa försök i två olika...

Højere udbytte i vårhvede og vårbyg
Provedor de dados: 21
Autores: Schou, Anders.
Vårhvede og vårbyg er hver for sig velkendte arter i det økologiske sædskifte, hvor vårhvede normalt dyrkes til konsum og vårbyg i stor udstrækning til foder. I sortsafprøvningerne lykkes det ofte, at opnå udbytter på over 50 hkg/ha, hvorimod udbyttet ude på bedrifterne ligger noget lavere. Særligt vårhvede ligger i praksis langt under 50 hkg/ha. I praksis er det derfor kun en mindre del af sorternes fulde udbyttepotentiale der udnyttes, hvorfor det er interessant at undersøge hvilke praktiske tiltag der kan hæve udbytterne.

In Europe, late blight, caused by Phytophthora infestans, is the most devastating disease affecting organic (and conventional) potato production. Under suitable environmental conditions the disease can spread rapidly and it can cause complete crop loss. The extent of damage due to late blight depends on several factors: in organic production systems these factors include climate, choice of variety, soil management and use of crop protection agents such as copper. Therefore, the extent of economic damage varies between European regions.    Council Regulation (EEC) No 2092/91, amended by Commission Regulation (EC) No 473/2002 of 15 March 2002 regulates the use of copper in organic agriculture. Copper has been the single most important control agent in...

Autores: Kienzle, J.
In the frame of the project “Arbeitsnetz zur Weiterentwicklung der Anbauverfahren des  ökologischen Obstbaus” (BOEL-project Nr. 03OE178) a group of fruitgrowers and advicers  started to discuss new measures and new concepts to enhance biodiversity in organic  orchards. Strips with flowering plants that can be integrated in the normal mulching system  and thus, do not originate vole problems, are actually tested on the farms. Other measures  as single bushes at the top and end of the rows are in discussion.  If such measures are to be integrated successfully in the practice of organic fruit growing,  the impulse must spring from growers themselves and their requirements regarding the  different risks must be considered. Otherwise, an acceptance in practice...

Essential oils can have an impact on pollen beetle (Meligethes spp.). Lavender oil (Lavendula angustifolia) showed the highest repellency value in a previous laboratory study (Mauchline et al., 2005). However, lavender oil is one of the most expensive essential oils – a fact that could seriously hamper on-farm implementation of this strategy. To find a cheaper essential oil with comparable efficacy to lavender oil, we compared the essential oils of Mentha arvensis, Eucalyptus globulus, Melaleuca alternifolia, Citrus sinensis, Citrus paradisi, Citrus limon, Juniperus mexicana, Abies sibirica, Illicium verum, Gaultheria procumbens, Cymbopogon flexuosus, Syzygium aromaticum, and Litsea cubeba using a Y-tube-olfactometer.

Ces dernières années, en agriculture biologique, les systèmes céréaliers sans élevage se sont développés, entrainant une dépendance des agriculteurs à des intrants azotés de plus en plus chers. Dans de tels systèmes de culture, associer un couvert de légumineuses à une culture de vente serait une solution pour régler le problème de l’autonomie azotée.   Dans les différents dispositifs mis en place, la croissance des couverts a été limitée cette année au cours de la période d’association avec le blé.

Regulation of Cydia pomonella in the Northern German climate
Provedor de dados: 21
Autores: Heyne, P.; Benduhn, B.; Fieger-Metag, N.; Maxin, P.
Population control of the codling moth (Cydia pomonella) is of great importance in  ecological fruit-growing. In the work described here we attempted (1) to determine the  efficacy of plant protection preparations certified for organic fruit production, and (2) to  develop a suitable application strategy. We found that a Granulovirus (Madex3), Bacillus  thuringiensis (Xentari) and Neem Azal were able to provide effective control of C.  pomonella. The reduced efficacy of Madex 3 as reported e.g. from some Southern  German orchards could not be observed in our trials.

Skadetærskler for bygbladplet, stribesyge og spiringsfusariose
Provedor de dados: 21

I partier med kraftige udsædsbårne smitte af bygbladplet var der udbredte primære angreb på de første blade og en efterfølgende  kraftig opformering af bladplet i bygafgrøden. Der kunne konstateres en tydelig korrelation mellem udsædsbåren smitte og de første primære angreb såvel som efterfølgende angreb. Denne korrelation var afhængig af sorten. Det anbefales, at grænseværdien for bygbladplet baseres på sortens resistensniveau over for sygdommen. Hvis sorten er fuldt modtagelig for bygbladplet forslås en grænseværdi på 5%, mens der i moderat resistente sorter kan accepteres 15% bygbladplet og i resistente sorter helt op til  25% bygbladplet.

Successful Blossom Thinning and Crop Load Regulation for Organic Apple Growing with Potassium-bi-carbonate (Armicarb®): Results of Field Experiments over 3 Years with 11 Cultivars
Provedor de dados: 21
Autores: Weibel, F. P.; Lemcke, B.; Monzelio, U.; Giordano, I.; Kloss, B.
With field trials over 3 years in a commercial organic orchard in Switzerland we have tested the efficacy of Armicarb® (potassium-bi-carbonate) for flower thinning in organic apple production. Over time, Armicarb was tested on 11 cultivars, at different application periods, in different concentrations, and always in comparison to other agents that are already allowed for thinning in organic fruit production in the European Union as e.g. lime sulphur, molasses, mechanical ropethinner or combinations of methods. Armicarb proved to be an efficient and reliable thinning agent with an efficacy similar to the now recommended methods with rope device, molasses or lime sulphur but has the advantage to be an environmentally very friendly product.

Size-specific susceptibility of the pest slugs Deroceras reticulatum and Arion lusitanicus to the nematode biocontrol agent Phasmarhabditis hermaphrodita
Provedor de dados: 21
Autores: Speiser, Dr. Bernhard; Zaller, Dr. Johann G; Neudecker, A.
The nematode Phasmarhabditis hermaphrodita is a commercially available biocontrol agent against slugs. This product is especially interesting for use in organic farming, where products containing metaldehyde or carbamates cannot be used for controlling pest slugs. We investigated the potential of P. Hermaphrodita for the control of the pest slugs Deroceras reticulatum and Arion lusitanicus. These two species are the most harmful slug pests in Switzerland. At different times of the year, we collected slug specimens of different weight and assessed their susceptibility to P. Hermaphrodita in the laboratory. Batches of five slugs were subjected to five different doses of nematodes plus an untreated control and replicated three times. During six weeks, feeding...

Foliar spraying of vermicompost extracts: effects on fruit quality and indications of late-blight suppression of field-grown tomatoes
Provedor de dados: 21
Autores: Zaller, Johann G.
The effect of foliar sprays with aqueous vermicompost extracts on growth, yields, morphological and chemical fruit quality and natural infection with late blight disease (Phytophthora infestans(Mont.) de Bary)) on three tomato varieties (Lycopersicon esculentum Mill., cv. Diplom F1, cv. Matina, cv. Rheinlands Ruhm) was investigated in a field experiment. Extracts were prepared of vermicompost produced from fruit, vegetable and cotton waste by redworms (Eisenia fetida Sav., Lumbricidae); tap water served as control treatment. Foliar application (spraying) of vermicompost extracts did not affect plant growth, biomass or nutrient allocation, or yields and number of fruits of the three tomato varieties; however, for several dates it significantly reduced the...

Economics of Hot Water Dipping
Provedor de dados: 21
Autores: P., Maxin; K., Klopp.
Hot water dipping is an appropriate method to protect apples against spoilage  caused by gloeosporium rot. Tests on the varieties Topaz and Ingrid Marie at the  OVB Jork (Germany) have demonstrated an effective reduction of spoilage from  between 80% and 92% in charges by an infection rate of 40%. The result of an  intensive R&amp;D process between 2002 and 2003 is the development of a praxis-tested  big box (300 kg) dipping station. With the first Bio Dipping systems now on the  market it has now been possible to analyse the economics of this process.  The costs of the systems per apple farm have been calculated from the fixed capital  costs for the system itself (including maintenance costs) and from the variable costs  based on an average crop of 250 t...

Latent infection rate of potato seed tubers with Phytophthora infestans (Mont.) de Bary – an underestimated problem
Provedor de dados: 21
Autores: Zellner, Michael; Keil, Sven; Benker, Marianne.
From 2007 to 2009 applying molecular methods a total of 17 batches of seed potatoes were tested for the rates of latent infections with Phytophthora infestans (Mont.) de Bary, the pathogen of late blight. The samples were chosen randomly from different certified European seed potato productions. The average infection rate of the seed potatoes tested was 11%. The highest occurring rate was 38%. The given data show that there is no significant correlation between late blight susceptibility-levels of varieties and rates of latent infestation. There were no statistically significant differences found between seed potatoes from organic and conventional production.

Seed born net blotch is a threat to the organic barley seed production in Denmark because it often exceeds the legal 15% infestation threshold in organically produced barley seed lots. Relationships among initial seed infestation levels, disease development during the growing season, yield parameters and net blotch infestation of the harvested grains were examined. Highly significant positive correlations among initial seed infestation, primary infection of seedlings and disease severity during the growing season as well as among disease severity at flowering and infestation of the harvested grains were found. The seed infestation level was much less than proportionally related to the primary infection of seedlings and to the disease severity later in the...

Igasuguse põllumajandustootmise, sealhulgas mahetootmise võtmeküsimuseks on kestliku mullaviljakuse tagamine. Mahetootmine põhineb kohaliku taastuva ressursi  tasakaalustatud kasutusel ning mullaviljakuse tagamiseks on väga tähtis hoolikalt läbimõeldud ja kohalikesse tingimustesse hästi sobiv külvikord. Külvikorra põhikultuuride vahel on mulla orgaanika ja taimetoitainete varu täiendamiseks otstarbekas  kasutada vahekultuure, mis külvatakse peale põhikultuuri koristamist. Vältimaks sügis-talvist taimetoitainete väljaleostumist tasub vahekultuurideks kasutada talvituvaid kultuure nn. talviseid vahekultuure, mis siis enne külvikorrakultuuri külvi mulda viiakse.

Root Weevil (Coleoptera: Curculionidae) and Ground Beetle (Coleoptera: Carabidae) Immigration into Strawberry Plots Protected by Fence or Portable Trench Barriers
Provedor de dados: 21
Autores: Bomford, Michael K.; Vernon, Robert S.
Physical exclusion shows some potential as a novel root weevil control strategy, but barriers to root weevil immigration may also exclude beneficial insects, such as ground beetles. A field study was undertaken in 1997 to assess the impact of two physical barriers—portable plastic trenches and aluminum fences with Teflon tape—on root weevil and ground beetle immigration into plots of strawberry, Fragaria x ananassa (Duchesne). Barypeithes pellucidus (Boheman) and Nemocestes incomptus (Horn), each comprised 43% of the root weevils caught at the site. Most (86%) of the ground beetles caught in control plots were longer than 1 cm, the width of the gap in the portable trench top. Trenches excluded 75 and 63% of B. pellucidus and N. incomptus, respectively,...

Pest management and biodiversity in organic fruit production: the case of apple orchards
Provedor de dados: 21
Autores: SAUPHANOR, B.; SIMON, S.; BOISNEAU, C.; CAPOWIEZ, Y.; RIEUX, R.; BOUVIER, J.C.; DEFRANCE, H.; PICARD, C.; TOUBON, J.-F.
Numerous pesticide applications are required for orchard protection, regardless of the guidelines. Organic fruit production (OFP) mainly relies on the use of mineral fungicides and microbiological or naturally-occurring insecticides. The environmental impact of this type of production does not significantly differ from that of conventional production when assessed in terms of synthetic indicators. However, the abundance of earthworms, as well as the abundance and specific richness of arthropod pests and beneficials in the orchards and surrounding hedges, is greater in OFP than in conventional orchards. Generalist predators are usually less affected by OFP compounds than by the chemical pesticides applied in conventional orchards. OFP also benefits avian...

Proteomic changes and endophytic micromycota during storage of organically and conventionally grown carrots
Provedor de dados: 21
Autores: LOUARN, Sébastien; Nawrocki, A.; Thorup-Kristensen, K.; Lund, O.S.; Jensen, O.N.; Collinge, D.B.; Jensen, B.
The physiological state of carrot roots during extended cold-storage is decisive for high postharvest quality. Wehave investigated differences in the proteome and micromycota of organically and conventionally grown carrots during six months of storage. The levels of only 15 proteins changed in level during storage. Proteins involved in cold stress adaptation and cytoskeleton components changed; these changes in specific protein levels occurred mainly during the first month demonstrating adaptation to storage conditions and that the carrots were subsequently stable, indicating stable carrot quality. The changes observed were similar in the two cropping systems. Using both biological isolation and a fungal PCR targeting the ITS region, we identified several...

Breeding apples with durable disease resistance
Provedor de dados: 21
Autores: Kellerhals, Markus; Kesper, Cornelia; Koller, Bernhard; Gessle, Cesare.
Apple cultivars with high fruit quality, good productivity and durable disease and pest resistance are highly required in ecological Fruit growing. In the past apple breeders mainly used single resistance genes giving good field resistance towards scab and mildew. They originate from wild species such as Malus floribunda 821, M. zumi and M. robusta. However, this type of resistance can be overcome by new pathogen races. Today the main emphasis is on the combination of functional different major resistance genes and the use of quantitative resistance to achieve durability. Molecular markers were developed which particularly permit the detection of major resistance genes. The combined presence of the target resistance genes in a seedling can be determined by...

Autores: ANON, AN.
Plant protection in arable and horticultural production was one of the central topics for research in the Federal Programme for Organic Agriculture. Since 2002, 53 projects have been carried out on this subject. After several status quo analyses (2002-2004), methods for control and prevention of pests and diseases were further developed and adapted to organic farming conditions. Focus areas included copper replacement, resistant varieties and improved cultivation methods. Plant health issues were also addressed in various speciality crops where pests and diseases often lead to the need to import produce from other European countries (e.g. Brussels sprouts), as domestic production cannot cover the ever-increasing demand; in this area, several projects were...

Le Sclerotinia est un champignon se conservant plusieurs années dans le sol sous forme de sclérotes. Il est particulièrement virulent sur salades, mais il est également inféodé à de nombreuses autres espèces maraîchères. Il est favorisé par de nombreux facteurs : salinité et teneur élevée en azote du sol, cultures intensives et rotations limitées, stress climatiques (périodes de gel, notamment à la reprise : jeunes plants non endurcis), irrigations excessives. En maraîchage biologique, l’absence de désinfection du sol et le niveau souvent élevé du sol en matière organique (donc en azote), favorisent la présence de cette maladie et provoquent des pertes très importantes à la récolte.

Autores: Keil, S.; Benker, M.; Zellner, M.; Kleinhenz, B.; Bangemann, L.W.; Zwerger, P.
Die Regulierung der Kraut- und Knollenfäule, verursacht durch Phytophthora infestans, stellt im ökologischen Landbau nach wie vor ein nur schwer zu lösendes Problem dar. Bislang ist eine befriedigende Befallsreduktion nur durch den Einsatz kupferhaltiger Pflanzenschutzmittel möglich, deren Einsatz durch die Anbauverbände, sofern überhaupt gestattet, auf 3kg pro Jahr begrenzt ist. Im Rahmen des Projekts „ÖKO-SIMPHYT“ wurden daher verschiedene Kupferapplikationsverfahren zur Bekämpfung der Phytophthora infestans-Sekundärinfektionen untersucht, um die zur Verfügung stehenden Kupfermengen optimal einzusetzen.

Persistence of pesticides in water from farm plots recently converted to organic farming
Provedor de dados: 21
Autores: SCHRACK, D.; COQUIL, X.; ORTAR, A.; BENOIT, M.
In Europe, the pervasive use of pesticides in agricultural areas has led to the deterioration of the quality of groundwater and surface water, resources earmarked for human consumption. The aim of the European Water Framework Directive 91/474 is to restore the “good ecological status” of surface water and to protect water that might be used for drinking water production by 2015. Interactions within the soil determine the fate of environmental pesticides. Water resource contamination may persist for a long time after the last use of pesticides (i.e., atrazine). Pesticide persistence is highly variable. The fate and persistence of pesticides in the environment depend on agricultural pesticide practices and on soil interactions, which are interrelated...

Use of liohumus extract for ecological control of potato late blight
Provedor de dados: 21
Autores: Patsaki, E.E.; Bourbos, V.A.; Balis, C.; Barbopoulou, E.A.
Ecological control of potato late blight caused by the fungus Phytophthora infestans (Μοnt) de Bary is based on forecasting programs, cultural practices (Shea and Broadbent, 1983), use of resistant cultivars (Umareus et al., 1983; Williams and Williams, 1994; Bradshaw et al., 1995) and application of suggested plant protective products.  Copper products are used only as preventatives and in limited quantities in order to avoid accumulation in the soil.

Adding value to vegetable waste: Oil press cakes as substrates for microbial decalactone production
Provedor de dados: 21
Autores: Laufenberg, Günther; Rosato, Pietro; Kunz, Benno.
In this study several oil press cakes were investigated as exclusive substrates for different moulds and yeasts for the production of flavor-active decalactones via solidstate fermentation (SSF). Experiments are focused on pre-treatment methods for olive cake to remove antimicrobial phenolic substances contained in the oil cake disturbing or even inhibiting microbial growth. Choosing Ceratocystis moniliformis as the reference microorganism best results were obtained by a combination of hot water flushes and enzymatic treatment of the cake. Fermentation with sunflower, olive and linseed cake did not lead to lactone formation in detectable amounts although all of these substrates provided good microbial growth. On castor cake, however, five microorganisms...

The introduction of the new control method of plant viruses infection for organic farming
Provedor de dados: 21
Autores: Kwon, S.B.; Chung, J.S.
Pepper mild mosaic virus (PMMoV) and cucumber mosaic virus (CMV) are economically important viruses, which cause enormous losses by infecting various vegetable crops. worldwide. Various strategies based on the avoidance of sources of infection, control of vectors have been conventionally employed to minimize the losses caused by these viruses. These strategies, however have not been effective as control tools. We have found that the extracts of gallnuts from Quercus dentate and Rhus javanica strongly inhibit PMMoV and CMV infection. The gallnuts are plant excretion produced when irritants are released by the larvae of gall insects. They contain high amounts of tannic acid such as gallic acid and ellagic acid. Also the gallnut extracts are widely used in...

Autores: Kuske, Stefan; Pilz, Christina; Kölliker, Ursula.
Fungal isolates of Beauveria bassiana (21 isolates), B. brongniartii (2), Paecilomyces  fumosoroseus (1) and Metarhizium anisopliae (1) were screened for virulence against  pollen beetle Meligethes aeneus. Most of the tested B. bassiana isolates originated  from naturally infected pollen beetles collected in Switzerland. In a lab bioassay adult  beetles were dipped into a defined conidial suspension and fungal infection was  recorded after 15 days. Seven isolates of B. bassiana as well as the P. fumosoroseus  F4K caused infection rates between 67.9% and 80% respectively and proved to be  promising strains for potential use against pollen beetles. However, more experiments  are needed to confirm their biological control potential under field conditions.

An Overview of Phytosanitary Risk Aspects of Composting by Organic Farmers
Provedor de dados: 21
Autores: Termorshuizen, Aad J.; Blok, Wim J.
Usage of compost in agriculture always brings about the risk of introducing plant pathogens. By proper composting, resulting in high temperatures during the thermophilic phase, compost can be applied safely. Organic farmers often prefer to compost organic residues themselves. The advantage of such an approach is that no material of foreign origin is introduced, but a drawback is the smaller scale of composting, which brings about greater phytosanitary risks. These risks can be dealt with by increasing the composting duration and by proper turning of the compost heap. If only organic residues from farms are composted, this usually results in low-quality composts because of the low lignin contents. Therefore, addition of materials that are high in lignin,...

The efficacy of different insecticides (neem, pyrethrin, spinosad, and rotenone) and a repellent (kaolin) applied with different strategies (single or repeated applications) against the over-wintering pear suckers (Cacopsylla pyri) and nymphs of the first generation was tested in a field trial in Switzerland in spring 2003. Rotenone, the only admitted product in Swiss organic agriculture, showed good effects. But, since Rotenone is toxic for non-target insects we looked for an alternative. The application of spinosad (Audienz) in combination with rape oil (Telmion) as well as the application of pyrethrum showed similar efficacy as rotenone. Neem had no or a very low impact on the pear sucker populations. The repellent kaolin (Surround® WP) showed the best...

DESIGNING MIXED HORTICULTURAL SYSTEMS
Provedor de dados: 21
Autores: Godin, E.; Tchamitchian, M.
The necessary ecologization of agriculture in the developed countries has recently resulted in the research of innovative systems that are both economically viable and environmentally friendly, with sustainable objectives at mid and long terms. The sylvoarable systems, mixing trees and crops on the same plot, are ecologically intensive systems that allow a better use of natural resources, hence increase production on the same land area. The vegetable orchard is a sylvoarable system mixing fruit trees and vegetable crops that disappeared in the 1950’s for economic reasons. Its possible reintroduction becomes a new research topic for ecological purposes, with agronomic bases to ensure its viability.  The vegetable orchards’ agronomic bases are a combination...

Regulierung der Kraut- und Knollenfäule (Phytophthora infestans) im ökologischen Kartoffelanbau
Provedor de dados: 21
Autores: Böhm, Herwart.
Zu den Krankheiten mit der größten Bedeutung im ökologischen Kartoffelanbau gehört die Kraut- und Knollenfäule (Phytophthora infestans). Durch diese Krankheit kann es je nach Witterungsbedingungen und damit je nach Befallsbedingungen zu deutlichen Ertragsausfällen kommen, die für ökologisch wirtschaftende Kartoffelanbauer einen enormen ökonomischen Verlust darstellen. Andererseits kann die Lagerstabilität und Qualitätsausbildung vermindert sein bzw. die Nachfrage nicht mehr ausreichend gedeckt werden.

Autores: Vogt-Kaute, W.; Spieß, H.; Jahn, M.; Waldow, F.; Koch, E.; Wächter, R.; Müller, K.J.; Wilbois, K.P.
A variety of physical treatment methods are able to kill pathogens on and in seeds non-selectively. In all cases, the application of these methods requires optimisation of the relevant treatment parameters such as temperature, treatment time or energy dose. The optimum treatment effect is achieved when the selected parameters induce a maximum reduction of infestation without relevant impairment of germination capac-ity and plant growth. It has been confirmed that different physical measures can be used for the control of seed-borne pathogens. The “classical” hot water treatment method is suitable for a wide range of seeds. Further procedures like the hot air seed treatment method “Thermoseed®”, the vacuum-steam treatment method Steamlab, and others are...

Field experiments with spring barley (Hordeum vulgare L.) and field pea (Pisum sativum L.) were carried out in three subsequent growing seasons 2004 to 2006 at the Hessian State Estate Frankenhausen located near Kassel in Central Germany. Spring barley and field pea were sown out as sole crops and intercropped with different seed rates in replacement and additive design, using two sowing modes: row by row (IC) and mixed intercropping (MC). Intercropping (IC and MC) was able to increase grain yield in most of the treatments. The Land Equivalent Ratio (LER) was always higher than 1, indicating that plant growth factors were used more efficiently by the intercrop than by the sole crop. Besides, the N content in spring barley grain was increased by...

Facilitating the registration of biocontrol organisms, plant extracts and semiochemicals in Europe
Provedor de dados: 21
Autores: Speiser, B.; Tamm, L.; Bale, J.; Fjelsted, A.; Hokkanen, H.; Menzler-Hokkanen, I.; Kuhlmann, U.; Strasser, H.; Hauschild, R.; Strauch, O.; Ehlers, R.U.
The legal regulation of plant protection products (Dir. 91/414/ EEC) is a bottleneck in the market introduction of new microbial biocontrol agents, plant extracts and pheromones. In contrast, invertebrate biocontrol agents (“beneficials”) are not registered at EU level.  The EU-funded project REBECA suggested improvements to accelerate the regulation process and make it more cost-effective, without compromises to the level of safety. Representatives of all stakeholder groups participated in the REBECA workshops. The EU Commission and Member States are encouraged to improve the registration of biocontrol organisms, plant extracts and semiochemicals at EU and/or national level.  The full proposals can be found at www.rebeca-net.de.

Optimierung der Saatgutgesundheit im ökologischen Arznei- und Gewürzpflanzenanbau
Provedor de dados: 21
Ein großes Problem im ökologischen Arznei- und Gewürzpflanzenanbau besteht darin, dass die Saatgutverfügbarkeit bis heute nur unzureichend ist und auch die Züchtungsarbeit bisher noch in den Anfängen steckt. So stehen kaum krankheitstolerante und -resistente Sorten aus ökologischer Vermehrung zur Verfügung. Einen Ausgleich für dieses Defizit soll die Verbesserung der Saatgutqualität bedeuten, denn geringe Keimfähigkeiten, schwache Triebkraft des Saatgutes und pilzliche Schaderreger führen zu verzögertem, lückigem Feldaufgang und späterem Erkranken der Bestände. Ziel des Projektes ist daher, die Saatgutqualität durch praxisrelevante Strategien wie Saatgutbehandlungsmethoden und pflanzenbauliche Maßnahmen (Saatgutaufbereitung) zu verbessern und gesundes,...

Selective flowers to attract and enhance Telenomus laeviceps (Hymenoptera: Scelionidae): a released biocontrol agent of Mamestra brassicae (Lepidoptera: Noctuidae)
Provedor de dados: 21
Autores: Barloggio, G.; Tamm, L.; Nagel, P.; Luka, H.
The importance of the right food source for the survival and reproduction of certain insect species is well documented. In the case of biocontrol agents, this is even more important in order to reach a high predation or parasitation performance. The egg parasitoid Telenomus laeviceps (Förster, 1861) (Hymenoptera: Scelionidae) is a promising candidate for mass release as a biological control agent of the cabbage moth Mamestra brassicae (Linnaeus, 1758) (Lepidoptera: Noctuidae). However, adult T. laeviceps need a sugar-rich food source to increase their parasitation performance and produce a good amount of female offspring. Released biocontrol agents were shown to benefit from conservation biocontrol, which includes the provision of selected flowers as...

Untersuchungen zur Wirksamkeit von Pflanzenextrakten gegen den Erreger des Falschen Mehltaus der Weinrebe (Plasmopara viticola)
Provedor de dados: 21
Autores: Kast, Walter K.
Ziel der Untersuchungen war die Suche nach Naturstoffen, die im ökologischen Weinbau die Anwendung von Kupfer gegen Rebenperonospora ersetzen oder ergänzen könnten. Zu diesem Zweck wurden Extrakte von einheimischen Pflanzen (Pflanzenteilen) zunächst einem Laborscreening unterworfen und die erfolgreichsten Extrakte an Topfpflanzen und schließlich in zwei Freilandversuchen (2000 und 2001) angewandt.   Die festgestellten Effekte der Pflanzenextrakte sind zwar signifikant, die im Freiland gefundene Wirkung ist aber für eine praktische Anwendung als Bekämpfungsmittel im ökologischen Weinbau zu gering. Sie wären allenfalls in Kombination z. B. mit Kupfer oder Gesteinsmehlen oder beim Anbau teilresistenter Reben nutzbar.

Screening of organically based fungicides for apple scab (Venturia inaequalis) control and a histopathological study of the mode of action of a resistance inducer.
Provedor de dados: 21
Autores: Bengtsson, M.; Jørgensen, H.J.L.; Pham, A.; Wulff, E.; Hockenhull, J.
A range of possible substitutes for copper-based fungicides for control of apple scab (Venturia inaequalis) in organic growing were tested in laboratory and growth chamber experiments in the Danish project StopScab (2002-2004). Eighteen crude plant extracts, 19 commercial plant-based products and 6 miscellaneous compounds were tested for their ability to reduce scab symptoms on apple seedlings. Most of the compounds were also tested for their effect on conidium germination on glass slides. Fourteen of the crude plant extracts, 13 of the commercial plant products and 5 of the miscellaneous compounds showed promising control efficacies when used either preventively or curatively in the plant assay. A histopathological study was carried out on the mode of...

Data from laboratory range-finder and field test indicate that both biological agents, Milsana (VP 2000) and B. brevis WT, can be judged well-suitable for use in organic or integrated control systems. There were no negative effects recorded against Typhlodromus pyri (Laboratory and field) and Aphidius rhopalosiphi (Iaboratory). For further confirmation, limit tests under GLP (with the highest tested concentration) will be performed in the near future. When Myco-Sin was applied in combination with Milsana in the field, population levels of T. pyri were raised compared to the control.

Influence of application strategy of coconut soap on the development of sooty blotch on apple
Provedor de dados: 21
Autores: Fuchs, J. G.; Haseli, A.; Tamm, L.
Sooty blotch causes heavy losses in Swiss organic apple production. In 2000 and 2001 a late season application strategy with coconut soap (Biofa Cocana RF) was evaluated. Coconut soap reduced disease occurrence in ali experiments. However, the efficacy was much higher in 2000 than in 2001, probably due to a much higher disease pressure in 2001.

Persistence of the biological effect of codling moth granulovirus in the orchard - preliminary field trials
Provedor de dados: 21
Autores: Kienzle, Jutta; Schulz, Christof; Zebitz, Claus P.W.; Huber, Juerg.
In 2000 and 2001, in a field trial, the persistence of the biological effect of codling moth granulovirus (CpGV) was investigated. With a single treatment at full concentration of CpGV (MADEX 3, 100 ml/ha) a considerable reduction of CM population was achieved over the whole vegetation period. This may indicate that over a considerable period of time after a treatment a biological effect of CpGV sufficient for an increased mortality of the larvae was present in the orchard. However, the onset of mortality was not fast enough to protect the fruit from damage. Further research has to be done to gain more experience in handling this effect. It could be very important for the reduction of the number of treatments in organic apple growing.

Strategien zur Regulierung verschiedener Nematodenspezies im Ökologischen Feldgemüsebau
Provedor de dados: 21
Autores: Kempkens, Karl; Paffrath, Andreas; Frankenberg, Andrea.
Im Ökologischen Gemüsebau wurden in den letzten Jahren vermehrt Schäden durch pflanzenparasitäre Nematoden beobachtet. Mögliche Gründe für die zunehmenden Probleme mit Nematoden liegen in der Fruchtfolgegestaltung. Ein hoher Anteil an Gemüsekulturen, Leguminosen und Untersaaten in der Fruchtfolge sowie ein hoher Beikrautbesatz sorgen für ein breites Wirtspflanzenspekrum für einige der stark schädigenden Nematodenarten. Regulierungsmöglichkeiten bestehen z.B. durch Eingliederung von Feind-, Fang und Nichtwirtspflanzen und resistenten Zwischenfrüchten in die Fruchtfolge. Weiterhin spielen Maßnamen im Anbaumanagement wie organische Düngung, Kalkung, Bodenbearbeitung, Bra-che, Saatzeitpunkte sowie physikalische und biologische Bekämpfung (Einsatz von...

Combined use of herbivore-induced plant volatiles and sex  pheromones for mate location in braconid parasitoids
Provedor de dados: 21
Autores: Xu, Hao; Desurmont, Gaylord; Degen, Thomas; Zhou, Guoxin; Laplanche, Diane; Luka, Henryk; Turlings, Ted C.J.
Herbivore-induced plant volatiles (HIPVs) are important cues for female parasitic wasps to find hosts. Here, we investigated the possibility that HIPVs may also serve parasitoids as cues to locate mates. To test this, the odour preferences of four braconid wasps – the gregarious parasitoid Cotesia glomerata (L.) and the solitary parasitoids Cotesia marginiventris (Cresson), Microplitis rufiventris Kokujev and Microplitis mediator (Haliday) - were studied in olfactometers. Each species showed attraction to pheromones but in somewhat different ways. Males of the two Cotesia species were attracted to virgin females, whereas females of M. rufiventriswere attracted to virginmales.  Male and female M.mediator exhibited attraction to both sexes. Importantly,...

Hot Water Dipping in Northern Germany- on farm results after four years of scientific work
Provedor de dados: 21
Autores: Maxin, Peter; Fieger-Metag, Nicole; Benduhn, Bastian; Kruse, Petra; Heyne, Peter.
In general, organic grown apples (Malus x domestica Borkh.) are not treated with chemical fungicides to pre-vent storage decay and these fruits may suffer up to 30% decay during storage. Preliminary experiments had shown that hot water dipping of apples may be an alternative. To inhibit Gloeosporium rot (Pezicula alba, P. malicortis) water temperature may be of about 50°C and dipping time from 60 sec up to 240 sec. The objec-tive was to determinate the suitable hot water treatment that prevent decay incidence and maintain fruit qual-ity (firmness, scale symptoms). In between the years 2002 and 2005 the test were repeated and a recom-mendation for the apple varieties in the area Northern Germany was elaborated.

Formulated and unformulated carbonates to control apple scab  (Venturia inaequalis) on organic apple
Provedor de dados: 21
Autores: Kelderer, Markus; Claudio, Casera; Lardschneider, Ewald.
In the EC at the moment only copper- and sulphur-based products are allowed to control  a variety of diseases on different crops. However, it is well-known that these products  also have negative side effects on beneficial organisms and the soil. For many years  researchers have been looking for alternatives to reduce their use and /or replace them.  Bicarbonates have been brought forward for many years. They are present in nature and  were used in the past in organic farming. Up to now, in the EC, carbonates have not been  included in the list of active substances, which may be used as plant protection products.  A good chance exists that this will change in the future, which would open the possibility  to apply for the inclusion of potassium hydrogen...

Im vergangenen Jahr haben Viren Erbsen und Ackerbohnen in manchen Regionen teils stark befallen und den Ertrag gemindert. Die Viren werden von Blattläusen übertragen, weshalb die Regulierung der Blattläuse immer wichtiger wird. Beim Anbau von Sommererbsen hat es sich generell bewährt, vorbeugend früh zu säen und frühreife Sorten zu wählen. So haben die Erbsen einen Wachstumsvorsprung und befinden sich in einem Stadium, in dem sie nicht mehr so anfällig sind, wenn die Schädlinge kommen. In der Regel haben Wintererbsen einen Entwicklungsvorsprung gegenüber Sommererbsen. Deshalb haben die Versuchsansteller des Thünen-Instituts untersucht, ob Erbsenblattläuse Wintererbsen weniger befallen und ob ein Gemengeanbau den Befall weiter verringert. Dazu fanden...

Improving disease resistance of pea - clues from plant-microbe interactions
Provedor de dados: 21
Autores: Wille, Lukas; Hohmann, Pierre; Messmer, Monika; Studer, Bruno.
Pea (Pisum sativum L.) is a valuable protein source for food and feed. Pea is able to significantly improve soil fertility and, hence, represents an ecologically important crop in low-input farming systems. Despite their importance, pea cultivation remains below expectations due to low and unstable yields caused by a complex of soil-borne pathogens. The goal of this project is to improve our understanding of resistance mechanisms of pea against soil-borne diseases. To achieve this goal, more than 300 pea lines were evaluated for resistance in pot-experiments and a subset of susceptible and resistant pea genotypes has been identified. In a next step, key pathogens and beneficials in the pea rhizosphere and the role of root exudates in determining the...

Commercial potting media often contain substantial amounts of peat that was mined from endangered bog and fen ecosystems. The main objectives of this study were to assess (1) whether the substitution of peat by vermicompost (VC) in potting substrate affects the emergence and biomass allocation of tomato seedlings (Lycopersicon esculentum Mill.) under greenhouse conditions and (2) whether VC amendments in seedling substrate affect tomato yields and fruit quality after plants were transplanted into equally fertilized field soil. Amended VC was produced of food and cotton waste in a windrow system by Eisenia fetida Sav.. Vermicompost amendments significantly influenced, specifically for each tomato variety, emergence and biomass allocation (root:shoot ratio)...

Provedor de dados: 21
Autores: Mattedi, L.; Forno, F.; Varner, M.; Umberto, P.
Codling-moth and applescab are the most important pathogens in both conventional and  organic apple productions. In order to control any phytopathological problem, it is  important to improve the knowledge of the behaviour of each specific pest. Since several  years (starting from 1986) we are improving in Trentino (North-Eastern Italy) the  observations of the population dynamics of codling-moth in order to find the best way to  control and treat this pest insect.  Constant monitoring and the knowledge of the characteristics of the different compounds  and possible methods to control the codling-moth (mating disruption, granulose virus and  specific nematodes) represent the most important basis to organize an effective controlstrategy.

Ökosystemdienstleistung im Apfelanbau: Vorkommen hymenopterer Parasitoide des Apfelwicklers (Cydia pomonolla)
Provedor de dados: 21
Autores: Pfitzner, H.; Herz, Annette.
During the last years, codling moth, a key pest in apple, became resistant to several plant protection products. Therefore it is of particular importance to search for  alternatives or additional plant protection strategies. Here we focus on the ecosystem service provided by hymenopterous parasitoids in pome fruit production. The aim is to  develop strategies for practical and sustainable use of functional biodiversity. Therefore basic knowledge on abundance and diversity of hymenopterous parasitoids  in different regions, their foodweb interactions and temporal occurence as well as their basic biology is necessary.

Birnenpockenmilbe: Nacherntebehandlung mit Schwefel
Provedor de dados: 21
Autores: Höhn, Heinrich; Linder, Christian; Daniel, Claudia; Wyss, Eric.
Die verschiedenen Exakt- und Praxisversuche sowie die ersten Erfahrungen von Praxisanwendungen zeigen, dass mit einer Nacherntebehandlung mit 2% Schwefel (entspricht 32 kg/ha bei einem Baumvolumen von 10 000 m3/ha) eine erfolgreiche Bekämpfungsmöglichkeit gegen Birnpockenmilben vorliegt. Raubmilben werden nach unserer Erfahrung kaum beeinflusst, da sie zu diesem Zeitpunkt bereits weitgehend die Winterquartiere bezogen haben. Auch andere negative Auswirkungen konnten wir bis jetzt nicht feststellen. Unter Berücksichtigung aller bisher bekannten Fakten muss in Zukunft für die Birnpockenmilbenbekämpfung bevorzugt die neu bewilligte Herbstbehandlung mit Schwefel empfohlen werden.

Chicory Grows Roots Below 3 m Is That Beneficial under Water Stress?
Provedor de dados: 21
Autores: Rasmussen, Camilla Ruø; Dresbøll, Dorte Bodin; Thorup-Kristensen, Kristian.
Introduction  Water scarcity is a major limitation to crop production worldwide. Deep-rooted crops can potentially allow exploitation of water that more shallow rooted crops cannot access. Several agricultural crops grow roots of several meters depth within a growing season, and thereby get access to water originating from wet season surplus precipitation stored in the soil. The aim of this study was to test the hypotheses 1) that chicory roots can grow below 3 m within a growing season and 2) that chicory shifts its water uptake downwards when the top soil dries out.    Materials and Methods  Chicory (Cichorium intybus L. cv Chicoree Zoom F1) was grown in 4 m tall rhizotrons in monoculture under dry or wet conditions and intercropped with either ryegrass...

High-temperature treatment for efficient drying of bread rye and reduction of fungal contaminants
Provedor de dados: 21
Autores: Kristensen, E.F.; Elmholt, S.; Thrane, U.
Mycotoxin producing fungi are natural contaminants of cereals and their toxins are harmful to humans and animals. Ochratoxin A (OTA) is among the most important. Heat treatment by drum drying does not eliminate already formed mycotoxins but the technique can reduce the number of viable fungi on the grain. The aim of this study was to establish a drying regime that kills fungal propagules on rye without reducing its quality for baking. Special attention was paid to some important mycotoxin producing species. As drying temperatures and retention time in the drum are essential, the drum drier must be equipped with an effective control unit. Two different control systems were tested. The results showed that fungi colonising the grain can be much more...

Entwicklung von Strategien zur Feuerbrandbekämpfung im ökologischen Obstbau
Provedor de dados: 21
Autores: Kunz, Stefan; Mendgen, Kurt.
Der Feuerbranderreger Erwinia amylovora kann an Apfel und Birne große wirtschaftliche Schäden verursachen. Um Feuerbrandepidemien abzuwenden, benötigt der ökologische Obstbau Strategien, die Blüteninfektionen verhindern. Seit 2004 wurden in diesem Projekt 44 Präparate in vitro und auf abgeschnittenen Blüten untersucht. Dabei zeigte sich, dass im Blütensystem nur Präparate die Symptombildung verhindern, die auch eine bakteriostatische Wirkung in vitro haben. In den insgesamt 11 Freilandversuchen nach EPPO-Richtlinie PP1/166 (3) bestätigten sich die im Labor an Blüten gefundenen Ergebnisse. BlossomProtect war in allen unseren Freilandversuchen mit durchschnittlich 78% Befallsreduktion das wirksamste Präparat, gefolgt vom Gesteinsmehlpräparat Myco-Sin mit...

Ecological studies of Trichoderma bio-inoculants in the soil ecosystem of Pinus radiata
Provedor de dados: 21
Autores: Hohmann, Pierre; Jones, E. Eirian; Hill, Robert A.; Stewart, Alison.
Three isolates of different Trichoderma species were selected for this study. T. hamatum (LU592) and T. harzianum (LU686), were known to stimulate growth and improve establishment of P. radiata seedlings, and T. atroviride (LU132) had no stimulatory activity. The ability of these isolates to establish and survive in bulk soil, the rhizosphere, rhizoplane or endorhizosphere of P. radiata seedlings was determined. In addition, the effect of each isolate on P. radiata seedling development and growth was assessed and is currently being confirmed in a large scale commercial experiment. From the nursery experiment, the Trichoderma isolate which was the most effective at colonising all P. radiata root subsystems (LU592) was selected for more detailed ecological...

Autores: Zimmer, J.; Hetebrügge, K.
Ziel des Projektes war die Erarbeitung eines Verfahrens zur Regulierung der Blutlaus (Eriosoma lanigerum), eines wirtschaftlich bedeutenden Schädlings im ökologischen Obstbau, gegen den es momentan keinerlei wirksame Bekämpfungsmöglichkeiten gibt. Hierzu wurde versucht, aus der Erfahrung vorangegangener Versuchsergebnisse ein Verfahren zur Bekämpfung der Blutlaus durch den Einsatz von Blutlauszehrwespen (Aphelinus mali) aus einer Nützlingszucht zu entwickeln und zur Praxisreife zu bringen. Die Zehrwespe ist ein natürlich vorkommender Gegenspieler, dem es aufgrund mangelnder Synchronisation zwischen Schädling und Nützling nicht rechtzeitig gelingt, den Schaden durch die Blutlaus zu verhindern. 2004 konnten mit dem Einsatz von parasitierten Blutlausmumien...

Control of seed borne diseases in production of organic cereals
Provedor de dados: 21
Autores: Nielsen, Bent; Borgen, Anders; Kristensen, Lars.
In production of organic seed it is important to have some control measures on seed borne diseases to avoid propagation and spread of serious diseases. Due to lack of acceptable treatment methods the only way for the moment is to discard seed lots with unacceptable infections. Experiments have been started to find new and alternative methods for controlling seed borne diseases. In spring barley the results show good effect with 5% acetic acid on leaf stripe (Pyrenophora graminea) but problems with unacceptable effects on seed germination have to be solved. The old method with hot water treatment can be used and the results indicate good results against leaf stripe using water at 55°C. The effect of hot water was enhanced by first soaking the seeds in water...

Preliminary Results on Contents of Resveratrol in Wine of Organic and Conventional Vineyards
Provedor de dados: 21
Autores: Lévite, D.; Adrian, M.; Tamm, L.
Phytoalexins are compounds synthesised by plants in response to various stresses. In grapevines, these compounds belong to the stilbene family. Several studies have shown that resveratrol is usually triggered by infection of berries by Botrytis cinerea. In organic viticulture, grapevines are usually more stressed by attempted or successful infections of various pathogens than in conventionally grown grapevines. Furthermore, crop protection agents such as acidified clays or copper may trigger defence reactions of the plants. The aim of this study was to verify if differences between organically and conventionally produced wines exist. The preliminary results will be used as a starting point for further research of quality aspects of organic grape-vine...

Efficacy of organic plant protection programs against Myzus cerasi on cherries
Provedor de dados: 21
Autores: Cahenzli, Fabian; Daniel, Claudia.
This project evaluated the efficacy of seven different organic plant protection programs against the black cherry aphid Myzus cerasi (MYZUCE) in a low stem cherry orchard. The standard paraffin oil (Weissöl) applied after bud swelling (BBCH 03) significantly reduced the number of infested long shoots and aphid colony size, represented by the number of curled leaves. Additional treatments with Pyrethrum (Pyrethrum FS) and Neem oil (Neem Azal T/S) added no further efficacy. Neem oil and Majestik applied twice showed only limited efficacy. A test oil was clearly less efficient than the standard paraffin oil. Ant baits placed on the stems after bud swelling to prevent ants from promoting aphids offered an interesting, sustainable control approach should for...

The effects of organic and integrated production systems on the culturable fungal microflora of stored apple fruits from five matched pairs of certified organic and integrated ‘Golden Delicious’ farms were studied at five representative production sites in Switzerland. Isolated fungi were identified morphologically. Colonization frequency (percentage of apples colonized), abundance (colony numbers), and diversity (taxon richness) were assessed for each orchard. The standard quality of the stored fruits was comparable for both organic and integrated apples and complied with national food hygiene standards. Yeasts (six taxa) and the yeast-like fungus Aureobasidium pullulans were the dominant epiphytes, filamentous fungi (21 taxa) the dominant endophytes. The...

Reducing russeting of organically grown Elstar to increase quality
Provedor de dados: 21
Autores: Jong, P.F.; van der Maas, M. P.
Sales organisations indicated that opportunities for organic apples sales can increase  when quality increases, in particular reducing the amount of russeting.  The use of copper is probably the most important factor for russeting. Therefore a worst  case scheme was compared with a scheme with reduced copper application. Furthermore,  there was a particular interest in the effects on russeting of potassium bicarbonate  (Armicarb) because this product might be an important element in a copper free fungicide  scheme. Application of Armicarb was investigated on wet or dry canopy and effects of two  different dosages were studied. All the schemes were compared with a worst case organic  fungicide scheme with copper. The experiment was done on two year old...

Innenbrand und Mineralstoffgehalte verschiedener Sorten Eis- und Kopfsalat aus biologisch-dynamischem Anbau
Provedor de dados: 21
Autores: Hagel, Dr. Ingo; Haneklaus, Prof. Dr. Silvia; Schnug, Prof. Dr. Ewald.
Im Salatkopf können die Blattränder Nekrosen (sog. Innenbrand) aufweisen. Dies steht in Zusammenhang mit einem unzureichenden Calcium Transport in die Blätter, da Ca als essentieller Baustein biologischer Membranen benötigt wird und Pektinsäure der Mittellamelle der Zelle zu Ca-Pektinat absättigt. Innenbrand kann bis zu Totalausfällen, einhergehend mit hohen Einnahmeverlusten führen. Die Ursache für diesen Qualitätsmangel liegt jedoch nicht in einem zu geringen Ca-Gehalt des Bodens, sondern u.a. in der Immobilität von Ca in der Pflanze, einem übermäßigen N-Angebot, einem zu schnellen Wachstum der Pflanze, ungünstigen Transpirationsbedingungen, empfindlichen Sorten sowie zu geringem Wurzelwerk. Offensichtlich werden bei der Züchtung neuer Sorten präventive...
