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...

Testing of strawberry-varieties (with/without biodegradable mulch film) for organic cultivation
Provedor de dados: 21
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...

Climate change and range shift of Igutettix oculatus
Provedor de dados: 21
Autores: Huusela-Veistola, E.; Söderman, G.
The leafhopper Igutettix oculatus (Lindberg) is a new arrival in Finnish fauna. I. oculatus has adapted to live on lilacs Syringa sp. The nymphs and adults feed sap on the underside of the lilac leaves and can cause substantial discoloration. Although yellowing of leaves seems to cause no harm to the growth of the lilacs, cosmetic damage and reduction of market value are obvious.

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...

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...

Regulierungsmaßnahmen des Drahtwurmbefalls im ökologischen Kartoffelanbau: Ergebnisse einer Status-quo-Analyse
Provedor de dados: 21
Autores: Schepl, Ute; Paffrath, Andreas.
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...

Autores: Wibe, Atle; Cross, Jerry V.; Borg-Karlson, Anna-Karin; Hall, David R.; Trandem, Nina; Sigsgaard, Lene; Baroffio, Catherine; Ralle, Baiba; Fountain, Michelle T.
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.

Autores: Lukas, Kathrin; Innerebner, Gerd; Kelderer, Markus; Finckh, Maria R.; Hohmann, Pierre.
The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence...

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.

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...

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.

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.

Nematoden im Ökologischen Gemüsebau - Ergebnisse einer Status-Quo-Analyse
Provedor de dados: 21
Autores: Frankenberg, Andrea; Paffrath, Andreas.
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...

Tomaten im Freiland. Die Suche nach Phytophthora-toleranten Sorten für den ökologischen Anbau
Provedor de dados: 21
Autores: Horneburg, Bernd.
Tomaten gehören zu den wichtigsten Gemüsen in Deutschland. Angebaut werden Tomaten im Klein- und Erwerbsgartenbau fast nur noch unter Glas oder Folie, weil im Freiland die Kraut- und Braunfäule (Phytophthora infestans (Mont.) de Bary) stark zugenommen hat. Sortensichtungen des Dreschflegel e.V. hatten seit 1996 gezeigt, dass Sorten mit interessanter Feldresistenz gefunden werden können. Ein Phytophthora-Schlüssel wurde entwickelt, um in Feldbeständen den Befall an Blatt, Stängel und Frucht zu dokumentieren. Durch mehrortige Sichtung konnten Sorten mit wichtigen agronomischen, morphologischen und phänologischen Eigenschaften für den Anbau im Freiland identifiziert werden. Die nicht-kommerzielle Saatgutarbeit hat dafür eine immense Bedeutung: Etwa 90% der...

Occurrence and importance of plant-parasitic nematodes in organic farming in Germany
Provedor de dados: 21
Autores: Hallmann, Johannes; Frankenberg, Andrea; Paffrath, Andreas; Schmidt, Harald.
In an attempt to evaluate the occurrence and economic importance of plant-parasitic nematodes in organic farming in Germany, a survey was conducted with the main emphasis on vegetable and cereal production systems. For vegetables, the survey included quantification and identification of plant-parasitic nematodes in soil samples and a questionnaire for growers querying production factors and damage levels. For cereals, the survey focused on quantification and identification of plant-parasitic nematodes in soil and plant samples. Overall, Pratylenchus and Tylenchorhynchus were the most prominent nematode genera under both production systems with an incidence of over 90% of the samples. Meloidogyne was detected in 51% of the samples in both systems. Other...

Status-Quo-Analyse und Entwicklung von Strategien zur Regulierung des Drahtwurmbefalls (Agriotes spp. L.) im Ökologischen Kartoffelanbau
Provedor de dados: 21
Autores: Paffrath, Andreas; Kempkens, Karl; Schepl, Ute.
Die Kartoffel ist die wichtigste Hackfrucht im Ökologischen Landbau. Sie eignet sich hervorragend für die Direktvermarktung und erbringt hohe Erlöse. 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%...

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, 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...

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.

Gibt es Alternativen zu Kupfer?
Provedor de dados: 21
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.

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.

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...

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.

Neben einer günstigen Fruchtfolgestellung hat die Auswahl einer geeigneten Art und Höhe an organischer Düngung eine entscheidende Bedeutung im erfolgreichen Kartoffelanbau. Es ist allgemein bekannt, dass Kartoffeln sehr zuträglich sind für eine hohe Versorgung mit organischer Substanz. Wenn in einer Fruchtfolge organische Düngemittel zur Ausbringung anstehen, sollten diese Düngemittel dann vorsorglich zu Kartoffeln verabreicht werden.  Ergebnisse über Erträge und Zusammensetzung von Kartoffelknollen aus Feldversuchen zur kurzfristigen und langfristigen Anwendung von organischen Düngemitteln wurden aus vielen Literaturquellen und eigenen Versuchen zusammengestellt und einer gemeinsamen Auswertung unterzogen. Ziel war es, aus diesen Daten erste verlässliche...

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...

Autores: Papp, Orsolya; Kolláth, Péter; Laszlo, Gyula; Drexler, Dora.
A biotermesztésben a cseresznyelégy elleni védekezés komoly kihívást jelent a gazdálkodók számára, mivel e kártevő ellen jelenleg nem áll rendelkezésre célzott, megbízhatóan hatékony, engedélyezett és az ökológiai gazdálkodásban is alkalmazható növényvédőszer. A termelők a gyakorlatban különféle olajos készítményeket vetnek be a kártevő ellen, a kezelések hatékonysága azonban meglehetősen bizonytalan, ismereteink szerint nem áll rendelkezésre róla hazai tudományos vizsgálat. Az olajos készítmények további problémája, hogy a vegetációs időszakban alkalmazva gyakran fitotoxikus hatásúak, és az olaj okozta stressz rontja a növények kondícióját. A jó minőségű, exportálható ökológiai cseresznyetermés előállításához ezért további megoldások felderítésére van...

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...

Sublethal effects of kaolin and the biopesticides Prestop-Mix and BotaniGard on metabolic rate, water loss and longevity in bumble bees (Bombus terrestris)
Provedor de dados: 21
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...

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.

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...

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.

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...

Kaolinbehandlungen gegen Obstschädlinge
Provedor de dados: 21
Schädlinge, wie der Gemeine Birnenblattsauger (Cacopsylla pyri) verursachen durch ihre Saugtätigkeit und die extremen Honigtauausscheidungen jährliche Ertragsausfälle. Bisher ist eine Bekämpfung des Gemeinen Birnenblattsauger nur mit dem stark nützlingstoxischen Rotenon möglich. Die Prüfung neuer, nützlingsschonender Mittel ist daher ein wichtiges Anliegen. Mit dem Produkt Surround® WP (Firma Engelhardt), welches in Kalifornien eingesetzt wird, um Sonnenbrand auf den Früchten zu verhindern, steht nun ein interessantes, neues Mittel zur Verfügung. Das Produkt auf der Basis des Tonminerals Kaolin überzieht die Bäume mit einer weissen Schicht, so dass sie für Insekten unattraktiv werden.

Autores: Pugliese, Massimo; Gilardi, Giovanna; Gullino, Maria Lodovica; Garibaldi, Angelo.
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.

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...

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.

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.

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.

Developing a partcipatory approach to seed production and varietal selection
Provedor de dados: 21
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.

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.

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...

Schädlingsregulation im Feldbau durch funktionelle Biodiversität
Provedor de dados: 21
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. Nötig ist zusätzlich eine massgeschneiderte, also funktionelle Biodiversität, die standort- und kulturspezifisch die Schlüsselantagonisten in Raum und Zeit optimal fördert. Deshalb werden am FiBL...

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...

Effect of cultural methods on leaf spot (Mycosphaerella fragariae) and gray mold (Botrytis cinerea) damage in strawberries
Provedor de dados: 21
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...

Biologische Bekämpfung der Maulwurfsgrille (Werre)
Provedor de dados: 21
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...

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.

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.

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...

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...

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...

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.

Predicting spring barley yield from variety-specific yield potential, disease resistance and straw length, and from environment-specific disease loads and weed pressure
Provedor de dados: 21
Autores: Østergård, H.; Kristensen, K.; Pinnschmidt, H.O.; Hansen, P.K.; Hovmøller, M.S.
Abstract For low-input crop production, well-characterised varieties increase the possibilities of managing diseases and weeds. This analysis aims at developing a framework for analyzing grain yield using external varietal information about disease resistance, weed competitiveness and yield potential and quantifying the impact of susceptibility grouping and straw length scores (as a measure for weed competitiveness) for predicting spring barley grain yield under variable biotic stress levels. The study   comprised 52 spring barley varieties and 17 environments, i.e., combinations of location, growing system and year. Individual varieties and their interactions with environments were analysed by factorial regression of grain yield on external variety...

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.

Möglichkeiten und Grenzen der Nutzung von Temperatursummen für die Terminierung von Aussaat und Umbruch einer Winterzwischenfrucht zur Kontrolle von Meliodogyne hapla im Ökologischen Landbau
Provedor de dados: 21
Autores: Fittje, Dr. Susanne; Hallmann, Dr. Johannes; Rau, Florian; Buck, Holger; Krüssel, Dr. Stefan; Warneke, Herman.
Pflanzenparasitäre Nematoden verursachen bedeutende wirtschaftliche Schäden im ökologischen Landbau (Paffrath et al. 2005). Vorwiegend  betroffen sind Betriebe mit einem hohen Anteil an Feldgemüse in der Fruchtfolge. Für Nematoden mit einem breiten Wirtspflanzenspektrum wie Meloidogyne hapla bieten sich über die Fruchtfolge, Unkrautbesatz und kurze Brachezeiten kontinuierlich Wirtspflanzen im Bestand. Insbesondere Leguminosen, eine entscheidende Stickstoffquelle im ökologischen Landbau, sind hervorragende Wirtspflanzen für M. hapla und andere pflanzenparasitäre Nematodenarten. Derzeit sind kaum praxisrelevante Maßnahmen zur Reduzierung pflanzenparasitärer Nematoden verfügbar oder aber, wie im Falle der Schwarzbrache, wenig ökologisch. Ziel des Projektes...

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.

Hopfen als Dauerkultur wird von vielen Schadorganismen befallen, die auch in Öko Betrieben regelmäßig bekämpft werden müssen. Brauereien, die Öko-Hopfen verwenden, stellen nämlich grundsätzlich die gleichen Qualitätsanforderungen an die Hopfendolden wie die Käufer konventionell erzeugter Ware.  Bei den verfügbaren Hopfensorten gibt es große Unterschiede in der Anfälligkeit gegenüber Krankheiten. Grundsätzlich wird der Öko-Hopfenpflanzer widerstandsfähige oder tolerante Sorten auswählen. Es gibt aber auch den Fall, dass ein Brauer für seinen Biertyp eine spezielle Sorte benötigt, die anfällig gegenüber Krankheiten ist.  Die wichtigsten Krankheiten, der Falsche Mehltau und der Echte Mehltau, werden in Öko Betrieben überwiegend mit kupfer- und...

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...

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).

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...

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.

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'...

Role of spontaneous plants as a reservoir of alternative hosts for Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan) (Hymenoptera, Eulophidae) in citrus groves
Provedor de dados: 21
Autores: Rizzo, Maria Concetta; Lo Verde, Valentina; Caleca, Virgilio.
The role spontaneous plants could eventually play towards populations of two exotic parasitoids, Semielacher petiolatus (Girault) and Citrostichus phyllocnistoides (Narayanan), was investigated in five Sicilian citrus groves. Both species were obtained from two herbs typically living beneath the citrus trees in the period of scarce availability of P. citrella larvae on citrus plants, and precisely: S. petiolatus was reared from Cosmopterix pulcherimella Chambers, leafminer on Parietaria diffusa M. et K., while C. phyllocnistoides on the same species and on a Liriomyza species associated to Mercurialis annua L., these last two host records being new for the parasitoid. Vegetational diversity can then enhance survival and maintenance of populations of exotic...

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...

Sustainable production of organic wheat
Provedor de dados: 21
Autores: Haigh, Z E L; Clarke, S; Hinchsliffe, K; Jones, H; Wolfe, M S.
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 input of farmers in the selection of...

Autores: Nechwatal, Jan; Zellner, Michael.
Die Kraut- und Knollenfäule der Kartoffel (Phytophthora infestans) kann im ökologischen Kartoffelanbau bislang nur durch die Anwendung von Kupferpräparaten effektiv kontrolliert werden. Im Rahmen eines Projektes zur Reduzierung des Kupfereinsatzes wurden mögliche kupferfreie Alternativen zur Blattapplikation gegen Phytophthora-Befall identifiziert. Da infizierte Pflanzknollen Ausgangspunkt für Krautfäule-Epidemien sind, sollen die Mittel nicht nur das Ausmaß des Blattbefalls während der Saison verringern, sondern auch die Menge der in den Boden eingewaschenen und auf die neuen Knollen verfrachteten Phytophthora-Sporen. In Labor-, Gewächshaus- und Freilandversuchen wurden kommerzielle und nicht-kommerzielle Präparate auf ihre Eignung als Kupferalternativen...

Apple scab control with grapefruit seed extract: no alternative to chemical fungicides
Provedor de dados: 21
Autores: Spitaler, Renate; Marschall, Klaus; Zidorn, Christian; Kelderer, Markus; Zelger, Roland; Stuppner, Hermann.
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...

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...

Experience with new fireblight resistant rootstocks in South Germany
Provedor de dados: 21
Autores: Ruess, Franz.
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...

Codling moth populations less susceptible to CpGV: What about higher concentrations?
Provedor de dados: 21
Autores: Kienzle, J.; Triloff, P.; 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, 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...

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.

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...

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....

Results of a Research Project about the influence of pruning intensity on cost of thinning by hand with the Variety ’Elstar’ in 2004 and 2005
Provedor de dados: 21
Autores: Eis, Birgit.
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...

Ökologische Krautfäulebekämpfung
Provedor de dados: 21
Autores: Benker, Marianne; Zellner, Michael.
Die Kraut- und Knollenfäule, verursacht durch den Erreger Phytophthora infestans, ist weltweit als eine der wichtigsten Krankheiten im Kartoffelanbau anzusehen. Im Ökologischen Kartoffelanbau stellt dieser Erreger nach wie vor ein ungelöstes Problem dar und kann hohe Ertrags- und Qualitätseinbußen verursachen. Während im konventionellen Kartoffelanbau effektive Verfahren, wie z.B. Prognosemodelle und zahlreiche Fungizide zur Verfügung stehen, kann der Befall im ökologischen Kartoffelanbau zur Zeit nur durch Einsatz von kupferhaltigen Pflanzenschutzmitteln reguliert werden, da ausgereifte Alternativen zur Zeit nicht zur Verfügung stehen. Dies reicht jedoch für eine effektive Krautfäulebekämpfung in Jahren mit hohem Infektionsdruck häufig nicht aus. Um...

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...

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...

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.

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...

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...

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...

Autores: Kuske, Stefan; Daniel, Claudia; Sarraquigne, J.-P.; Jermini, M.; Conedera, M.; Peters, A.; Grunder, J. M.
Survival of pest in micro-plot trials (container studies) or field plot trials was monitored after exposure to commercially used EPN strains. Experimental plots were artificially infested with pest larvae that naturally burrowed into the soil for diapause. Either larval mortality or adult emergence, was assessed to estimate the control effect of the EPN treatment. Here we present preliminary results from three ongoing projects.

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 the timing of fungicides to control Sooty Blotch in organic apple growing. First results in 2003
Provedor de dados: 21
Autores: Trapman, Marc.
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.

Provedor de dados: 21
Autores: Nazareno, N.R.X.; Skora Neto, F.; Canalli, L.B.S.; Araujo, A.G.; Campos, J.F.
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...

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...

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...

Experiences of Wheat dwarf virus in Finland 2004-2007
Provedor de dados: 21
Autores: Erlund, Patrik.
The occurance of Wheat dwarf virus (WDV) was reported for the first time in Finland in year 2004.   Based on field observations made by advisors from 2004 and 2007 the most important factor influencing WDV infestation appeared to be the tillage. Due to random incidence of Wheat dwarf virus, forecasting is of great importance.

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.

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...

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...

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...

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.

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...

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...

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.

Biotic indicators of carabid species richness on organically and conventionally managed arable fields
Provedor de dados: 21
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...

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.

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...

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...

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...

Rapid treatment monitoring by field spectroscopy
Provedor de dados: 21
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...

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...

Provedor de dados: 21
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.

Provedor de dados: 21
Autores: Larbi, M.; Gobat, J.-M.; Fuchs, J. G.
Extracts of green waste compost have been shown to inhibit plant diseases. In this study, the factors influencing the mechanism of inhibition of apple scab (Venturia inaequalis) and grapevine downy mildew (Plasmopara viticola) were studied. Extracts were prepared from samples of 30 composts from commercial composting plants. Composts were extracted with 1:2 or 1:5 water for 2 or 7 days. Extracts were applied to seedling of apple and grapevine. The seedlings were artificially inoculated with V. inaequalis or P. viticola, respectively and incubated under controlled conditions. After inoculation, severity of diseases and lesion diameter were measured. The incubation time and the compost/water ratio did not influence the capacity of the extracts to protect the...

Einsatz und Etablierung von Raubmilben zur nachhaltigen Spinnmilbenkontrolle in der Sonderkultur Hopfen
Provedor de dados: 21
Autores: Jereb, Marina; Schwarz, Johannes; Weihrauch, Florian.
Ziel dieses von der BLE geförderten Projektes (FKZ 12NA014) ist es, durch Untersaaten in den Fahrgassen geeignete Überwinterungsquartiere zu schaffen, die es ermöglichen, eine konstante Population der Raubmilben über mehrere Vegetationsperioden hinweg zu etablieren. Im Hopfenbau ist eine nachhaltige Spinnmilbenkontrolle derzeit nicht möglich, da im Herbst die oberirdischen Pflanzenteile komplett abgeerntet und somit auch die potentiellen Überwinterungsstrukturen genommen werden. Aus diesem Grund wurden (1) Rohrschwingel Festuca arundinaceae, (2) Große Brennessel Urtica dioica und (3) Kleinblütiges Franzosenkraut Galinsoga parviflora ausgesät und auf ihre Eignung als Überwinterungsquartier getestet.

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.

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...

Kassationsprocenter som følge af udsædsbåne svampe i økologisk udsæd af korn og bælgsæd i 1999-2005
Provedor de dados: 21
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...

REDUCTION DES APPORTS CUPRIQUES EN VITICULTURE BIOLOGIQUE:ETUDE DU LESSIVAGE FOLIAIRE SOUS SIMULATEUR DE PLUIE;
Provedor de dados: 21
Autores: MOLOT, Bernard; GAIMON, Cyril.
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.

Results from scab trials with Armicarb in the years 2006 and 2007
Provedor de dados: 21
Autores: Pfeiffer, B.
In organically cultivated orchards of the LVWO Weinsberg in the years 2006 and 2007  trials were carried out about new products and their efficacy against apple scab. In the  year 2006 (variety ‘Gala’) Armicarb and BioPluss sprayed preventively during primary  ascospore season could not convince, also not in combination with lime sulphur as stopapplication.  Armicarb showed at ‘Gala’ a tendency to increase russetting of the fruits. In  the year 2007 (Variety ‘Elstar’) different combinations of wetting sulphur with yuccasaponin  and stop-applications (lime sulphur, Armicarb) were tested with focus on the time  immediately after blossom. The effect of Armicarb as stop-application was weaker than of  lime sulphur at an infection-period with extreme high...

Dem Ökologischen Landbau stehen derzeit keine richtlinienkonformen Verfahren mit ausreichender Wirksamkeit und/oder arbeitstechnischer Effizienz zur Verfügung, um die gesetzlichen Auflagen in der Saatgut-Produktion einzuhalten. Schon mehr als drei bzw. fünf an Flug- und/oder Hartbrand erkrankte Ähren pro 150 qm in der Basis- bzw. Z-Saatguterzeugung führen zur Aberkennung der Vermehrungsbestände und somit zu beträchtlichen finanziellen Einbußen. Einen Ausweg böte der Anbau von resistenten Sorten. Hierzu wurden 2002-03 und 2004-05 die verfügbaren Handelssorten auf ihre Anfälligkeit gegenüber Hartbrand und seit 2000 insgesamt 274 Wintergerste-Genbankmuster bzw. Handelssorten gegenüber Gerstenflugbrand geprüft.

Auswirkungen von PEN, einem Extrakt aus der Biomasse von Penicillium chrysogenum, auf Pathogene und Pflanzen
Provedor de dados: 21
Autores: Tamm, L.; Rentsch, C.; Guyer, U.; E., Mösinger.
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. Unter den Resistenzinduktoren (Elicitoren) sind vor allem diejenigen von grossem Interesse, die Resistenz gegen Pathogene auslösen, die ansonsten mit Kupfer bekämpft werden (Tamm, 2000).

Field tests with Madex Plus against CpGV-resistant codling moth populations in organic orchards in 2006
Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Volk, F.; Zebitz, C.P.W.
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,...

Versuche zum praxisgerechten Betrieb von Barrieresystemen zur Abwehr von Wühlmausschäden im ökologischen Obstbau
Provedor de dados: 21
Autores: Walther, Bernd; Pelz, Hans-Joachim.
Im Ökologischen Obstbau verursachen Schermäuse (Arvicola terrestris) und Feldmäuse (Microtus arvalis) erhebliche Schäden durch das Benagen der Rinde und Wurzeln von Obstbäumen. Um die Zuwanderung dieser Schaderreger in sensible Kulturen dauerhaft zu verhindern, können Migrationsbarrieren eingesetzt werden. Migrationsbarrieren sind niedrige Zäune aus engmaschigem Drahtgitter, das 50 cm tief in die Erde eingegraben wird und das 40 cm über den Boden hinausragt. Die Oberkante der Migrationsbarriere wird rechtwinklig nach außen umgebogen, um ein Überklettern durch Scher- und Feldmäuse zu verhindern. In den Zufahrtsbereichen wird das Drahtgitter oberirdisch durch flexible Polyolefin-Folie ersetzt. Zwischen März 2004 und Dezember 2006 wurde ein zeitsparendes und...

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...

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...

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.

Autores: Pfeiffer, Barbara.
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.

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...

Development of "Blossom-Protect" - a yeast preparation for the reduction of blossom infections by fire blight
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".

Our insect immigration warning system was built on the atmospheric dispersion model that has been used in predicting long-range transport of airborne pollen. We observed immigrations with a trap network consisting of rotating tow-nets, yellow sticky traps, and suction traps.    Based on our studies the aphids can be detected with radars when they occur in large numbers.

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;...

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...

Autores: Sharma, MSc Kalpana; Schulte-Geldermann, Dr. Elmar; Bruns, Dr. Christian; Finckh, Prof. Maria R.
Three biofertilizers (BF) and three plant strengtheners (PS) were tested in comparison  to chemical fertilizer application and BABA (DL-3-amino-n-butanoic acid), respectively  for their effects on the reactions of six different tomato varieties against three isolates  of Phytophthora infestans in detached leaf disk assays. All experiments were repeated  twice with six replicates each. Two of the BF (BioIlsa and Biofeed Quality) significantly  reduced late blight severity as compared to horn meal and chemical fertilizer with no  fertilizer by isolate and fertilizer by variety interactions. All PS significantly reduced  susceptibility of all tomato varieties. However, the interactions among PS, variety and  isolates were highly significant suggesting that...

Hopfen als Dauerkultur wird von vielen Schadorganismen befallen, die auch in Öko Betrieben regelmäßig bekämpft werden müssen. Brauereien, die Öko-Hopfen verwenden, stellen nämlich grundsätzlich die gleichen Qualitätsanforderungen an die Hopfendolden wie die Käufer konventionell erzeugter Ware.  Bei den verfügbaren Hopfensorten gibt es große Unterschiede in der Anfälligkeit gegenüber Krankheiten. Grundsätzlich wird der Öko-Hopfenpflanzer widerstandsfähige oder tolerante Sorten auswählen. Es gibt aber auch den Fall, dass ein Brauer für seinen Biertyp eine spezielle Sorte benötigt, die anfällig gegenüber Krankheiten ist.  Die wichtigsten Krankheiten, der Falsche Mehltau und der Echte Mehltau, werden in Öko Betrieben überwiegend mit kupfer- und...

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....

Autores: Hein, W.; Waschl, Hermann.
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.

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...

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...

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.

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...

Der Einsatz von phosphithaltigen Pflanzenstärkungsmitteln (Frutogard) ist ebenfalls möglich.  Im Rahmen des Verbundprojektes sollen auf den ausgewählten Pilotbetrieben neue Verfahren zur Peronosporabekämpfung sowie Strategien zur Kupferminimierung getestet werden.

Madex Plus and Madex I12 overcome Virus Resistance of Codling Moth
Provedor de dados: 21
Autores: Zingg, D.
Over the past three years, codling moth populations with resistance to the Mexican isolate  of Cydia pomonella Granulovirus (CpGV) have been found in Germany, France, Italy,  Switzerland and the Netherlands. Andermatt Biocontrol has tested two new virus isolates  (Madex Plus and Madex I12) which can overcome CpGV-resistance, and compared them  in the field. Both isolates proved effective against Mexican isolate resistant codling moth  populations, in several locations. In Switzerland, Madex Plus has been already approved  for use.

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...

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...

Susceptibility to Apple Scab, Nectria Cancer and Powdery Mildew of Different Unsprayed Apple Varieties
Provedor de dados: 21
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. The reference variety  Elstar/Elshof was in all plantings among the most...

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....

Rapid Emergence of Baculovirus Resistance in Codling Moth to Dominant, Sex-linked Inheritance
Provedor de dados: 21
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),...

Abstract: The impact of treatments  with the pyrethrin insecticide Pyrethrum FS and the repellent kaolin product Surround WP to control the autumn forms of Dysaphis plantaginea Pass. (Homoptera: Aphididae), a major pest insect on apple, was assessed in one-year field experiments in Switzerland. 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...

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...

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...

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.

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...

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...

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...

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.

Autores: AZIM, Khalid.
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...

Autores: Anon,.
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.

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.

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...

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...

Evolutionary breeding of healthy wheat: from plot to farm
Provedor de dados: 21
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...

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...

Tolerance to weed harrowing in four spring barley varieties
Provedor de dados: 21
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...

Control of the apple sawfly Hoplocampa testudinea Klug in organic fruit growing
Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Maxin, P.; Rank, H.; Bathon, H.; Zebitz, C.P.W.
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. If the conditions for applications  are good and the infestation is not too high, the normally...

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.

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...

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.

Betydning af udsædsbåren angreb af ærtesyge
Provedor de dados: 21
Autores: Nielsen, G.C.
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).

Selbstregulierende Apfelanlage: Erfahrungen aus sieben Versuchsjahren in der Schweiz
Provedor de dados: 21
Autores: Cahenzli, Fabian; Schärer, Hans-Jakob; Pfiffner, Lukas; Daniel, Claudia.
Eine Apfelanlage zu konzipieren, die ganz auf Prävention und die Selbstregulation der Schadorganismen setzt und komplett ohne Pestizide auskommt, war die Idee im Projekt „Sustainable Fruit System (SFS)“ am Forschungsinstitut für biologischen Landbau (FiBL) (Frick, Schweiz). Nach sieben Versuchsjahren ziehen wir Bilanz: Die Schädlingsprävention funktionierte recht gut, schwieriger war die Situation bei den Pflanzenkrankheiten. Im Artikel beschreiben wir die Apfelanlage, die eingesetzten Präventionsmaßnahmen, die Erfolge, Rückschläge, Erfahrungen und Lehren aus dem Versuch.

Report on seed born diseases in organic seed and propagation material
Provedor de dados: 21
Autores: Micheloni, C.; Plakolm, G.; Schärer, H.
The key questions which will be addressed in this report are:  • Are seed born diseases an important factor that prevents seed companies from producing organic seeds and organic farmers from using them?  • Which seed treatments are available in organic farming? Which treatments are or will be acceptable? To which degree are they effective?  • Are the thresholds for seed born diseases different among Member States? Can this cause unfair competition among farmers and seed producers?  • How did the health status of organic seed change in the last years?  The main answers may be synthesized as follows:  • Seed born diseases are an important factor influencing seed production and seed use in organic agriculture, but they are not the only obstacle that exists at...

Regulation According to EU Directive 91/414: Data Requirements and Procedure Compared with Regulation Practice in Other OECD Countries
Provedor de dados: 21
Autores: Hauschild, Rüdiger; Speiser, Bernhard; Tamm, Lucius.
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.

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...

Kirschessigfliege Drosophila suzukii: Ein neuer Schädling im Weichobstanbau
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
Die Kirschessigfliege Drosophila suzukii wurde 2008 nach Europa eingeschleppt. Im Mittelmeerraum wurden 2011 starke Schäden vermeldet. In diesem Jahr ist auch nördlich der Alpen mit Schäden zu rechnen. Die Fliegen befallen alle Weichobstarten (Beeren, Kirschen, Trauben), sowie viele wilde Pflanzen. In diesem Jahr sollten alle sensiblen Kulturen mit Fallen überwacht werden. Zur Befallsvorbeugung werden der Einsatz von engmaschigen Netzen (0.8 mm), sowie eine frühzeitige, vollständige Ernte und das Vernichten befallener Früchte empfohlen. Zur Regulierung von Drosophila suzukii in Beeren-, Steinobst- und Rebkulturen hat das Bundesamt für Landwirtschaft eine Sonderbewilligung für den Einsatz von diversen Insektiziden im Jahr 2013 erlassen.

Autores: Bloksma, Joke; Jansonius, Pieter Jans.
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...

Reduzierung des Blattlausbefalls an ausgewählten Gemüsekulturen durch Mulchen mit verschiedenen Materialien und Farben
Provedor de dados: 21
Autores: Hommes, Martin; Siekmann, Gitta; Piepenbrock, Olaf; Baur, Ursula; Fricke, Andreas; Thieme, Thomas.
Ziel des Projekts war die Prüfung von Mulchmaterialien im ökologischen Pflanzenschutz zur Reduzierung des Blattlausbefalls in Freilandgemüse. Weizenstroh und farbige Polypropylenvliese wurden in diversen Gemüsekulturen auf mehreren Standorten in Norddeutschland eingesetzt. Versuchsdurchführung und Datenerhebung wurden durch extreme Niederschläge und durch Trockenheit und Hitze erheblich beeinflusst. Bei dem Einsatz von Strohmulch in Brokkoli, Buschbohne und Dicker Bohne war der Blattlausbefall auf einem von zwei Versuchsstandorten bis zu 50 % vermindert. Die Wirkung war auf einen verringerten Einflug von Blattläusen in strohgemulchte Parzellen zurückzuführen. Strohmulch zeigte in Kopfsalat keine Wirkung auf den Blattlausbefall. In Möhren war die Anzahl...

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...

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...

Net blotch severity is best assessed at early grain filling with respect to its effect on grain weight of spring barley
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Vollmer, Jeanette H.; Østergård, Hanne; Munk, Lisa.
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: 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...

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...

New methods for organic raspberry production in polyethylene tunnels
Provedor de dados: 21
Raspberries for the fresh market is a new and very profitable crop in Norway, and the production in polyethylene tunnels is increasing rapidly. In Norwegian organic production, the experience so far is that using tunnels is a prerequisite if growing for the fresh market. The project focuses on the major bottlenecks in organic tunnel production of raspberries. The project will develop methods for controlling the most damaging pests (raspberry beetle, aphids and mites) and methods for secure and efficient supply of organic nutrients in tunnels. The research on raspberry beetle is a co-operation with Sottish Crop Research Institute.   An important task in this project is to extend the growing area for tunnel production further north, by utilizing the long...

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....

In the Austrian research project “Basic principles for breeding, multiplication and  variety testing for organic agriculture” (from 2004 until 2008) novel methods for the  assessment of the suitability of seed and cultivars for organic farming were developed  and evaluated by an interdisciplinary co-operation of researchers, breeders and  variety testers. Organic farming requires specific combinations of crop plant  characters, especially seed health and resistance against seed-borne diseases.  Another crucial feature is the competitive ability against weeds. Early development  was found to significantly increase the competitiveness of different crop plants.  Genotypic variation in characters necessary for an efficient utilisation of below-ground...

Autores: Kidmose, Ulla; Christensen, Lars P.; Lindhard Pedersen, Hanne; Thybo, Anette K.
To ensure a high, stable production of blackcurrant juice in Denmark, it is necessary with high-yielding blackcurrant cultivars, which are resistant against pest and diseases, and that have a high sensory quality and high health value. In this experiment, blackcurrant juice processed from berries of 12 organic cultivars was screened. A trained sensory panel using descriptive sensory profiling evaluated the sensory quality of the juice samples. In addition, the aroma profile and the content of vitamin C were determined in the juice samples. The results showed that the following sensory attributes: blackcurrant aroma, blackcurrant flavour, fruity flavour, pungent flavour, sweetness and sourness varied significantly in the 12 juice samples.

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...

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...

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...

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...

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.

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...

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).

Provedor de dados: 21
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...

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....

Surround zur Kontrolle der Kirschessigfliege Drosophila suzukii auf Weintrauben
Provedor de dados: 21
Autores: Cahenzli, Fabian; Daniel, Claudia.
Im Sommer 2016 wurde an den Weinsorten Gamaret und Garanoir in Frick ein Versuch angelegt,um die Wirksamkeit von Surround (Kaolin) in zwei verschiedenen Konzentrationen (18 &amp; 24 kg/ha), mit drei Applikationen alle zwei Wochen, gegen die Kirschessigfliege Drosophila suzukii zu testen.  Aufgrund des geringen Befallsdruck konnte im Versuch bei drei Terminen bis zur Ernte keine Eiablage im Rebberg festgestellt werden. Es konnten keine Nebenwirkungen von Surround 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 acht Tage nach der letzten Behandlung Beeren geerntet, die im...

Prediction and detection of long-range migration of pest insects
Provedor de dados: 21
Autores: Markkula, Irmeli; Leskinen, Matti; Pylkkö, Pirkko; Ooperi, Sini; Tiilikkala, Kari; Ojanen, Hannu; Raiskio, Sakari; Koistinen, Jarmo.
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...

Einfluss von Feldgröße, Geometrie und der Nachbarkultur auf den Befall mit Phytophthora infestans und auf die Ertragsbildung in Kartoffelbeständen
Provedor de dados: 21
Autores: Finckh, Maria R.; Bouws-Beuermann, Heidi; Bruns, Christian.
Genetische Vielfalt und das Mikroklima innerhalb eines Feldes kann die Entwicklung von Epidemien massiv beeinflussen. In Kartoffelbeständen kann Vielfalt durch Sortenmischungen in der Reihe, alternierenden Reihen oder Streifen verschiedener Sorten (siehe Finckh et. al. 2003, dieser Band) oder im Streifenanbau abwechselnd mit anderen Kulturen erreicht werden. Beim Streifenanbau mit verschiedenen Kulturen sind eine große Anzahl Anbaufaktoren beeinflußbar wie Feldlänge und - breite, Ausrichtung zum Wind und die Art der Nachbarkulturen. Diese können, wenn sie höher als die Kartoffelbestände sind als Barrieren für Wind und Krankheitsinokulum dienen, eventuell aber auch die Bestandesfeuchte erhöhen. Niedrigere Kulturen dagegen können die Bestandesfeuchte...

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...

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.

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...

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.

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.

A new system for evaluating inputs for organic farming
Provedor de dados: 21
Autores: Speiser, Bernhard.
With developments in agriculture always in a state of flux organic standards and regulations can act as a factor against innovation in organic farming. Nowhere is this more obvious than in the control of inputs. To improve this situation, a EU-funded Concerted Action project "Organic Inputs Evaluation" was set up. Below are the proposals developed by the project.

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...

Impact of Gateway Organic Fertilizer on Herbivorous and Non-Parasitic Nematodes Associated with Telfairia Occidentalis Hook F. Field
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...

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...

Autores: Pautasso, Marco; Döring, Thomas F.; Garbelotto, M; Pellis, L; Jeger, MJ.
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. A summary of observed and predicted climate changes, as well as of direct effects of climate...

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...

Autores: Wibe, Atle; Cross, Jerry V.; Borg-Karlson, Anna-Karin; Hall, David R.; Trandem, Nina; Sigsgaard, Lene; Baroffio, Catherine; Ralle, Baiba; Fountain, Michelle T.
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.

Biological Control of Woolly Apple Aphid (Eriosoma lanigerum HAUSM.) with Aphelinus mali HALD.
Provedor de dados: 21
Autores: Hetebrügge, K.; Fieger-Metag, N.; Kienzle, J.; Bathon, H.; Zebitz, C.P.W.; Zimmer, J.
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...

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.

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.

Autores: Luka, Henryk; Leimgruber, Andrea; Willareth, Martin; Nagel, Peter; Pfiffner, Lukas; Wyss, Eric; Schlatter, Christian; Schied, Johannes; Traugott, Michael.
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...

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...

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...

Antallet af jorddiger i Danmark er faldet meget, i takt med at markerne er blevet større. Store marker er praktiske, men den store afstand til uforstyrrede områder forringer chancerne for en god bestand af nyttedyr som rovbiller, mariehøns og edderkopper. Netop de arter har brug for græs eller høje urter som gemmested eller til overvintring.

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...

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.

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.

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.

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...

Falscher Mehltau an Gurke - Regulierung durch gezielte  Klimaführung und Sortenwahl im Unterglasanbau
Provedor de dados: 21
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.

Pflanzenstärkungsmittel: Was können sie wirklich? – Erfahrungen aus dem Biogemüsebau
Provedor de dados: 21
Autores: Koller, Martin.
Pflanzenstärkungsmittel sind nicht nur im Bioanbau verbreitet, auch manch anderer Betrieb setzt auf ihre Wirkung, obwohl die Werbung oft viel mehr verspricht, als die «Wundermittel» beim genauen Hinsehen in der Praxis bewirken können. Pflanzenstärkungsmittel, die gemäss Düngeverordnung für den Anbau zugelassen sind, sind im Bioanbau nur dann erlaubt, wenn sie in der offiziellen Hilfsstoffliste für den biologischen Anbau aufgeführt sind. Neben den Handelsprodukten sind selbst hergestellte Aufgüsse und Tees (z.B. Brennnesseljauche) in Gebrauch, auf die hier aber nicht näher eingegangen wird.

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...

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...

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.

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.

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...

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...

Fruit quality of Elstar en Santana in the Netherlands
Provedor de dados: 21
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...

Tærskler til udsædsbåren bygbladplet
Provedor de dados: 21
Autores: Pinnschmidt, H.O.
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.)

Could phosphite be a new fungicide for organic farming?
Provedor de dados: 21
Autores: Speiser, Bernhard; Tamm, Lucius.
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. Short pea varieties generally seem to be more susceptible to seed infection by Ascochyta than taller varieties.

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...

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...

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.

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...

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.

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...

In the last years the contro I 01 the apple sawfly Hoplocampa testudinea Klug was not efficient in organic Iruit growing. This was due to quality problems 01 the "Quassia wood" used lor the treatments. First orientating criteria based on one 01 the active ingredients, Quassin, were established lor the quality 01 "Quassia" preparations. A lield test on apple sawfly showed, that the quantity 01 Quassin per ha required lor good sawfly control is about 12-18 9 Quassin. In the nex! years, more active ingredients (Le. Neoquassin) have to be included in the quality criteria and evaluated by biotests. Only this way, reliable recommendations can be given to the growers.  NeemAzal-T/S was effective only against the secondary inlestation. Thus, it can be recommended...

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.

Are there alternatives to copper for controlling grapevine downy mildew in organic viticulture?
Provedor de dados: 21
Autores: Dagostin, Silvia; Schärer, Hans-Jakob; Pertot, Ilaria; Tamm, Lucius.
Downy mildew caused by the obligate biotrophic oomycete Plasmopara viticola is one of the most important and devastating diseases of grapevine. 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...

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,...

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...

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...

Fruit growing: fertilization, fruit quality, crop protection, hedgerows, biodiversity
Provedor de dados: 21
A survey has been carried out in two experimental organic orchards located at the INRA experimental station of Gotheron near Valence (Southeastern France). The program also associated the GRAB (Groupe de Recherche en Agriculture Biologique, Avignon). The aims were:(i) to acquire references about peach and apple organic farming; (ii) to improve the management of organic orchards by integrating some results of previous research; and (iii) to measure on the long term the effect of organic farming on the soil and on the arthropod community of the orchard.  Soils were shallow and washed out stone soils presenting low pH, low organic matter content and low CEC (Cationic Exchange Capacity). Both orchards had been organically managed since planting, realised in...

Herbstapplikationen mit Schwefel – eine neue Möglichkeit zur Bekämpfung der Birnenpockenmilbe Eriophyes pyri
Provedor de dados: 21
Autores: Daniel, Claudia; Linder, Christian; Wyss, Eric.
Trotz ihrer geringen Körpergrösse von nur 0.16 - 0.20mm kann die Birnenpockenmilbe, Eriophyes pyri (Pagenstecher) (Acari: Eriophyidae) starke Schäden an Blättern und Jungfrüchten von Birnen verursachen. 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...

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...

Die gute alte Fruchtfolge als Bekämpfungsmethode gegen den  Maiswurzelbohrer (Diabrotica virgifera virgifera LeConte)
Provedor de dados: 21
Autores: Bertossa, M.; Schaub, L.; Colombi, L.
Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae), the western corn rootworm  (WCR), is an immigrant from North America and one of the top ten global agricultural  pest species. Within the last 15 years, WCR invaded Europe at 3 focal points, and has  been steadily extending its domain soon threatening commercial maize production.  After the first detection in Switzerland in 2000 near Lugano, careful observations by  pheromone trap monitoring of this quarantine organism have been realized.  Experiences with WCR whose populations dynamics are incompletely understood,  have also been studied by installing a continuous maize field comparing population  dynamics with rotated maize fields in the immediate surroundings. Our experiences  with WCR...

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...

Enhancement of degradation of fallen apple leaves
Provedor de dados: 21
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...

Kocheigenschaften und Geschmack von ökologisch und konventionell erzeugten Kartoffeln stimmen nicht immer überein. Auch im Lager ist die Entwicklung der Geschmackseigenschaften unterschiedlich: Manche Sorten bevorzugen Kühllager mit konstanten Temperaturen, andere ein Belüftungslager.  Um herauszufinden, wie sich der Geschmack während der Lagerung verändert, fanden in den letzten zwei Jahren in Westfalen-Lippe Testessen nach der Ernte, im Winter und im zeitigen Frühjahr statt. Sechs bis zwölf Tester verkosteten bis zu 18 Sorten. Getestet wurden Kartoffeln aus vorgekeimtem und nicht vorgekeimtem Pflanzgut. Fleischfarbe, Feuchte, Kochfestigkeit und Geschmack sowie der Gesamteindruck der Knolle wurden bewertet. Die Kartoffeln wurden teils in einem Kühllager...

Olive fly (Bactrocera oleae) activity, fruit infestation and temperature in an organic table olive orchard in southern Crete
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.

Einfluss von Armicarb (Kalium Bikarbonat) auf den Schorf und Regenfleckenkrankheit des Apfels
Provedor de dados: 21
Autores: Tamm, Lucius; Amsler, Thomas; Fuchs, Jacques G.; Schärer, Hans-Jakob; Refardt, Matthias.
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.

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...

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

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...

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.

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...

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.,...

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 effect of mixed cropping semi-leafless peas with linseed dodder (Camelina sativa (L.) Crtz.) on weed development and pest incidence was investigated in small plot experiments in Northern Hessen, Germany, over two years. Mixed cropping peas together with linseed dodder had a significant suppressive effect on weed-coverage, in average 62 % efficacy in 2003 and 54 % in 2004, compared to mono cropped peas. The infestation level of pea aphid (Acyrthosiphon pisum) and the damage incidence of pea moth (Cydia nigricana) in harvested peas, was neither significantly reduced nor enhanced. In both years mixed cropping peas gained a relative surplus in yield compared to peas grown as a sole crop. The results demonstrate the advantageous complementary use of...

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...

Impact of different Agents on the Efficacy of Codling Moth Granulovirus in Tank Mixtures
Provedor de dados: 21
Autores: Fritsch, E.; Undorf-Spahn, K.; Huber, J.; Kienzle, J.
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...

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...

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...

Test du Contans, produit biologique à base de Coniothyrium minitans en traitement de sol contre Sclerotinia spp. sur laitue : intérêt d'un traitement après la plantation
Provedor de dados: 21
Autores: Lambion, Jérôme; Mounier, Jean-Michel.
Le Contans (société BIPA/Belchim), composé du champignon antagoniste Coniothyrium minitans, a été homologué en 2003 en traitement de sol contre le Sclerotinia. L’objectif de cet essai est de tester dans différentes conditions (culture, calendrier,…) l’efficacité du Contans en traitement en plein avant plantation complété par un traitement après plantation. Le Contans montre des efficacités différentes dans les 2 sites d'essai. Sur le site 1, 2 traitements répétés permettent d'accroître le poids de salades intactes récoltées par parcelle élémentaire (environ 2 kg contre 1,3 kg dans le témoin non traité). Par contre, sur le site 2, les traitements avec le Contans ne semblent apporter aucune protection. Sur ce site, l'observation des sclérotes enfouis montre...

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.

Nano-particles in organic production? Issues and opinions
Provedor de dados: 21
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...

Molecular Characterisation of the Ribgrass Mosaic Virus - Impatiens
Provedor de dados: 21
Autores: Hohmann, Pierre.
Several molecular characteristics of the Ribgrass mosaic virus - Impatiens (RMV-Imp) were investigated in this thesis including the evaluation of three mutation constructs in virulence and virus accumulation on Nicotiana (N.) benthamiana and N. tabacum. Regarding a strategy of expressing foreign genes in plants, two diverged RMV-based expression vectors containing a green fluorescent protein were cloned into the binary vector pPZP200 for subsequent agroinfiltration work. An infectious full-length clone of RMV and three RMV-based mutants already existed. They vary depending on which of the two putative ORFs is inactivated. An additional mutation site of one of these mutation constructs was discovered and reverse mutated. After the inoculation of the...

Resistenter Ölrettich zur Regulierung von Wurzelgallennematoden im ökologischen Landbau
Provedor de dados: 21
Der Wurzelgallennematode Meloidogyne hapla ist einer der bedeutenden Schaderreger im ökologischen Anbau von Feldgemüse und Kartoffeln. Untersuchungen innerhalb dieses Forschungsvorhabens bestätigten die teils hohen Besatzdichten mit M. hapla auf ökologisch bewirtschafteten Betrieben. Faktoren wie weite Fruchtfolge, hoher Anteil an Leguminosen, Gemüse und Hackfrüchte (Wirtspflanzen) bei gleichzeitig geringem Anteil an Getreide (schlechte Wirtspflanzen) in der Fruchtfolge, kurze Brachezeiten sowie oftmals unzureichende Unkrautregulierung bedeuten ein fast kontinuierliches Vorhandensein an Wirtspflanzen für bestimmte pflanzenparasitäre Nematoden, insbesondere für M. hapla.

En Finlande, la culture biologique du colza est importante depuis plus longtemps que chez nous. Après un démarrage difficile, les agriculteurs biologiques finlandais ont atteint une surface de près de 3000 hectares de colza. L’expérience finlandaise peut nous être précieuse surtout dans le domaine de la lutte contre le méligèthe et dans celui des sous-semis (semis de couverture).  La Finlande cultive en bio 2000 à 3000 hectares de colza d’été depuis près de 10 ans. L’huile de colza pressée à froid du pays ne se vend pas seulement dans les magasins bio, mais aussi dans la plupart des supermarchés. Cela n’empêche pas la demande de dépasser l’offre, et les huileries prennent de nouveaux producteurs sous contrat.

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...

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.

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...

Provedor de dados: 21
Autores: Kelderer, Markus; Lösch, Robert; Lardschneider, Ewald; Casera, Claudio.
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...

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.

Pflanzenverträglichkeit von verschiedenen Schwefelpräparaten auf Braeburn bei Behandlungen mit dem Sprüher oder mit der Oberkronenberegnung
Provedor de dados: 21
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 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.

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.

Reducing the use of copper in potatoes
Provedor de dados: 21
Autores: Dierauer, Hansueli; Siegrist, Franziska; Weidmann, Gilles.
• 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....

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...

Einfluss von Extremtemperaturen in Getreidelagern auf die Parasitierungsleistung von Nützlingen im Vorratsschutz
Provedor de dados: 21
Autores: Niedermayer, Steffi; Steidle, Johannes L. M.
The application of parasitic wasps against stored pests is a common method for the protection of stored products in ecological farming. Temperature measurements in stores show that there are extreme temperatures during a year (extreme cold/hot). Field tests were made to show the influence of these extreme temperatures on the parasitation ability of beneficial insects.

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...

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...

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.

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.

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...

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.

Possible solutions for replant problems caused by soil-borne pathogens in  organic strawberry production
Provedor de dados: 21
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...

As part of a research project 13 cultivars were planted in 2005 at 11 sites on 9 farms in 5  different Austrian regions. The aim was to find new cultivars tolerant to soil-borne  pathogens and leaf/fruit diseases, with high yield, winter hardness and good fruit quality, to  serve as alternative to the highly susceptible cultivar ‘Elsanta’, regarding soil-borne  diseases. Plant vigour and infestation with Verticillium dahliae and leaf diseases were  evaluated in 2005 und 2006 at 7 sites and in 2007 at 3 sites.  In addition, following parameters were assessed on 2 organically managed sites in 2006  and 2007: marketable yield, percentage of different categories of unmarketable fruits and  incidence of the blossom weevil. In 2006 fruit characteristics and...

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, Ina; Zimmer, Jürgen; Trautmann, Martin; Fieger-Metag, Nicole; Buchleither, Sascha; Bathon, Horst.
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: Kehrli, Patrik; Cahenzli, Fabian; Daniel, Claudia; Linder, Christian.
Même si la présence de la drosophile du cerisier (Drosophila suzukii) dans les vignobles suisses a provoqué une grande inquiétude auprès des viticulteurs en 2014, les expériences acquises ces deux dernières années montrent que la vigne doit être considérée comme une plante hôte secondaire. Malgré cela, des oeufs peuvent être pondus dans les baies de divers cépages. Avec l’aide des services cantonaux, nous avons échantillonné plus de 90 000 baies dans 500 parcelles en 2015, ainsi que 150 000 baies dans 600 parcelles en 2016. L’analyse de ces données montre que la sensibilité du raisin augmente avec la maturation, que les cépages rouges Acolon, Cabernet Dorsa, Cornalin, Divico, Dornfelder, Dunkelfelder, Galotta, Garanoir, Humagne rouge, Mara, Regent et Syrah...

Grünlandbewirtschaftung mit differenzierter Intensität - Ausgewählte Ergebnisse eines Parzellenversuchs am Standort Dummerstorf
Provedor de dados: 21
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...

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...

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...

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...

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...

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...

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...

Provedor de dados: 21
Autores: Köppler, Kirsten; Storch, Volker; Vogt, Heidrun.
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.

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...

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...

Autores: Sharifi, Shervin; Karimi, Javad; Hosseini, Mojtaba; Rezapanah, Mohammadreza.
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...

Autores: Fleck, Michael; von Fragstein, Peter; Heß, Jürgen.
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.

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...

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.

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...

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...

Vergleichende Analyse der Mykotoxinproblematik im konventionellen und ökologischen Getreidebau
Provedor de dados: 21
Autores: Loges, Ralf; Eberle, Marco.
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...

Autores: Waldow, F.; Jahn, M.
Vier unterschiedlich anfällige Weizensorten wurden in 6 Stuten (20-5000 Sporen/Korn) inokuliert und 6 alternativen Behandlungsverfahren unterzogen. In Klimakammerversuchen wurde mittels Frühsymptomen (chlorotische Blattflecken) zu BBCH 14 der potenzielle Befall erfasst. Alle Sorten hatten bereits in der niedrigsten Stufe Frühsymptome, in der höchsten Stufe waren bis 56 % der Pflanzen befallen. Trotz standardisierter Versuchsbedingungen war die Symplomausprägung sehr uneinheitlich. Die Auswirkung der Behandlungen auf den Frühbefall war bei den Sorten unterschiedlich, tendenziell zeigten Tillecur und Heißwasser eine gute, mikrobielle Präparate wenig Wirkung.  Da die Bestimmung des Blattbefalls als einzige Methode zur Prognose des Ährenbefalls nicht...

Limaces et escargots en agriculture biologique : quelle alternative au métaldéhyde ?
Provedor de dados: 21
Autores: Lambion, Jérôme.
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. Les modalités d'application de ce produit (date des apports, localisation) doivent donc encore être affinées. En outre, l'utilisation en grandes cultures...

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...

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...

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...

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...

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...

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...

Attractive plant volatiles as a control method against apple fruit moth (Argyresthia conjugella Zell.)?
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...

Provedor de dados: 21
Als ein richtungsweisender Ansatz zur Verbesserung der Pflanzkartoffelproduktion im ökologischen Anbau ist die Nutzung der natürlichen Abwehrkräfte der Kartoffeln anzusehen. Die in Kartoffelknollen vorkommenden Glykoalkaloide können antibiotische Reaktionen sowie eine Anti-Fraß-Wirkung auslösen. Durch eine Belichtung von Kartoffelknollen ist eine verstärkte Akkumulation von Glykoalkaloiden in den Knollen möglich. Der Schwerpunkt dieses Projektes wurde deshalb auf die Verbesserung der Pflanzgutqualität durch eine Belichtung der geernteten Knollen während bestimmter Phasen der Lagerperiode gelegt. Lichtbehandlungen mit verschiedenen Lichtspektren unter Berücksichtigung von Belichtungsdauer, Terminen und Sortenunterschieden sowie dem Vergleich von natürlicher...

Optimisation of downy mildew (Plasmopara viticola) control in organic viticulture with low copper doses, new copper formulations and plant strengtheners,  results of four years of on farm research
Provedor de dados: 21
Autores: Hofmann, U.; Heibertshausen, D.; Baus-Reichel, O.; Berkelmann-Loehnertz, B.
In three different wine growing regions in Germany, due to weather and infection conditions several fungicide (copper formulations) and plant strengtheners (Myco-Sin VIN®, Kendal®, Frutogard ®) applications against downy mildew are required in order to obtain satisfactory disease control. Results of the four years of on farm trials confirmed good efficacy of the copper based substances like copper hydroxide, partly in combination with two or three applications of potassium phosphonate, new copper-hydroxide formulation or copper oxychloride used in a low doses of   copper   and alternative products like Myco-Sin-VIN® (clay with high aluminium  content) in combination with Kendal® ( plant extract).

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...

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.

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.

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,...

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...

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.

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...

Autores: Walther, Bernd; Pelz, Dr. Hans-Joachim.
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...

Plant pathogens as climate change indicators in Finland
Provedor de dados: 21
Autores: Jalli, Marja.
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.

Potato virus Y transmitting aphids in a Finnish seed potato area
Provedor de dados: 21
Autores: Kirchner, S.M.; Hiltunen, L.; Virtanen, E.; Döring, T.F.; Valkonen, J.P.T.
The aphid-transmissible Potato virus Y is a major problem in seed potato production (Valkonen , 2007).    The aphid flight activity was monitored from mid-June to the end of August with a suction trap and with yellow pan traps in 2007 and 2008.    Previous studies have concluded that potato colonising aphids are not the main vectors of Potato virus Y.

Effects of landscape and region on pests and pathogens in Brassica vegetables and oilseed rape
Provedor de dados: 21
Autores: Daniel, Claudia; Collier, Rosemary; Thomas, Jane; Hommes, Martin.
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 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...

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...

Prüfung von Saatgutbehandlungen an Karotten
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...

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...

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...

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....

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.

Autores: Dorn, Brigitte; Musa, Tomke; Krebs, Heinz; Fried, Padruot; Forrer, Hans-Rudolf.
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...

Phytotoxicity of different sulphur products applied with the sprayer or with the overheat irrigation system on Braeburn apples
Provedor de dados: 21
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...

Die Wirkung der Saatgutbehandlung mit Milchsäure auf den Alternaria-Blattbefall kurz vor der Ernte war nicht genügend hoch. Die Wirkung lag je nach Satz und Erhebungsdatum zwischen 19 und 58 %, war aber zu keinem Zeitpunkt statistisch gesichert. Der Anteil an Sekundärinfektionen (also nicht durch die ursprüngliche Infektionsquelle) war wahrscheinlich hoch (Morgennebellage, durch Windfang umschlossene Parzelle). Ein zusätzliche Untersuchung an Standorten mit weniger hohem Befallsdruck wäre sinnvoll. Die Keimrate des behandelten Saatgutes war mit 62-70 % zu gering. Durch den lückigen Karottenbestand war der Anteil an übergrossen Karotten hoch. Eine zusätzliche Erhebung der Triebkraft wäre sinnvoll, um allfällige Beschädigung am Saatgut besser feststellen zu...

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...

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...

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.

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,...

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
Provedor de dados: 21
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...

The effect of organic amendments on clubroot (Plasmodiophora brassicae)
Provedor de dados: 21
Autores: Davies, Gareth; Jones, Catherine.
This report was presented at the UK Organic Research 2002 Conference. Clubroot (Plasmodiophora brassicae) is an important disease of organic brassica crops. Organic soil amendments were added at realistic rates and times to infested organic soil in pot trials in order to evaluate their effect on the disease. Both chitin and straw amendments reduced disease incidence compared to other amendments but straw also reduced plant vigour.

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.

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.

Autores: Perri, Dr Enzo; Iannotta, Dr Nino; Muzzalupo, PhD Innocenzo; Russo, Dr Anna; Caravita, Dr Maria Anna; Pellegrino, Mr Massimiliano; Parise, Mr Attilio; Tucci, Mr Paolo.
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.

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....

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...

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...

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.

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.

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...

Ausbreitung des Rapsglanzkäfers innerhalb eines Feldes und in der Landschaft
Provedor de dados: 21
Autores: Géneau, Céline; Schlatter, Christian; Daniel, Claudia.
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...

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.

Provedor de dados: 21
Autores: Spornberger, A.; Sinkovits, D.; Pieber, K.
In the search for methods of reducing direct pest control in organic fruit growing, several farmers in South Tirol and Austria who have experience in this field were visited. At the same time, various cultivars of apple, pear and peach were observed in the research orchard of the Institute for Fruit Production and Horticulture at the University of Agricultural Sciences in Vienna. Clear differences among varieties with regard to their susceptibility to important pests and diseases were readily observable. The necessity of testing cultivars in organically managed systems using a minimum of direct plant protection was emphasized by many farmers. The farmer's experience and our own observations demonstrated that soil management, fertilization, rootstocks,...

Besondere Risiken für den Ökologischen Landbau durch die Einschleppung und Verbreitung von invasiven, gebietsfremden Arten
Provedor de dados: 21
Autores: Gärtig, Susanne; Kehlenbeck, Hella.
Der Ökologische Landbau ist aufgrund seiner Produktionsform stärker als der konventionelle Pflanzenanbau durch die Einschleppung invasiver gebietsfremder Arten gefährdet. In diesem Zusammenhang wurden die derzeit in der EU-Richtlinie 2000/29/EG gelisteten Quarantäneschadorganismen bezüglich der von ihnen ausgehenden potentiellen Bedrohung für den Ökologischen Landbau geprüft. Die aktuellen Regelungen und Anforderungen zum Schutz des Kulturpflanzenanbaus können kein vergleichbares Schutzniveau für den Ökologischen Landbau bewirken, wie es für den Konventionellen Landbau möglich ist, weil diese auf Bekämpfungsmaßnahmen basieren die im biologischen Anbau nicht angewendet werden können. Weiterhin wurden relevante Schadorganismen die keinen Regelungen...

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.

Regulierung des Kleinen Fruchtwicklers im ökologischen Obstbau
Provedor de dados: 21
Autores: Zebitz, Claus P.W.; Kienzle, Jutta; Kopp, Barbara.
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.

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.

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. Resistenzzüchtung)...

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...

Auswirkungen von Saatstärke, weiter Reihe und Sortenwahl auf Ertrag und Backqualität von Winterweizen [Effects of seed rate, row spacing and variety on yield and baking quality of winter wheat]
Provedor de dados: 21
Autores: Pommer, G.
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).  Since synthetic...

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...

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...

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...

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.

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...

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-...

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.

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...

Utilisation du cuivre en viticulture, arboriculture et maraîchage biologique :   impact sur les sols, et recherches de méthodes de réductions des doses et d’alternatives à son utilisation  « Raisonnement de l’usage du cuivre en agriculture biologique »
Provedor de dados: 21
Ce programme a été élaborée grâce à l’association des compétences l’INRA et de plusieurs ICTA (Instituts Techniques), sur une problématique commune à plusieurs espèces (vigne, pêcher, pommier, tomate) : l’usage du cuivre et ses conséquences en agriculture biologique. Il a pour objectif de proposer des réponses à court et moyen terme, sur deux plans différents. Un plan réglementaire avec une obligation de réduction des apports de cuivre à brève échéance et un plan environnemental, il paraît en effet difficile à une agriculture qui se veut écologique et durable de maintenir l’usage de produits dont on connaît à terme la nocivité sur les sols et la vie qui s’y développe. Au vue de l’importance prépondérante du cuivre pour la maîtrise d’un très grand nombre de...

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.

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...

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...

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...

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...

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
Autores: Pinnschmidt, H.O.
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.   Angreb af Fusarium på kernerne var korreleret med spireevne af kernerne og fremspiring i marken. Kvantificering...

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...

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,...

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...

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...

Plant protection in organic arable and horticultural 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.
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.

Möglichkeiten zur Optimierung der Kupferwirkung gegen Krautfäule im Ökologischen Kartoffelanbau
Provedor de dados: 21
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. Control of the pathogen has been reported with the use of Fusarium sambucinum (Klukov et al., 1983) and Pythium ultimum (Kuznetsova et al., 1995) extracts. Bacteria of Bacillus genus were successfully used in tomato plants in vivo (Sadlers, 1996). Pseudomonas fluorescens strain ΑP33 and other bacteria...

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...

Gezielte Belichtung von Kartoffelknollen – Ein umweltschonendes Verfahren zur Produktion von gesundem Pflanzgut im ökologischem Anbau
Provedor de dados: 21
Autores: Benker, Marianne; Peters, Rolf.
Als ein richtungsweisender Ansatz zur Verbesserung der Pflanzkartoffelproduktion im ökologischen Anbau ist die Nutzung der natürlichen Abwehrkräfte der Kartoffeln anzusehen. Die in Kartoffelknollen vorkommenden Glykoalkaloide können antibiotische Reaktionen sowie eine Anti-Fraß-Wirkung auslösen. Durch eine Belichtung von Kartoffelknollen ist eine verstärkte Akkumulation von Glykoalkaloiden in den Knollen möglich. Der Schwerpunkt dieses Projektes wurde deshalb auf die Verbesserung der Pflanzgutqualität durch eine Belichtung der geernteten Knollen während bestimmter Phasen der Lagerperiode gelegt. Lichtbehandlungen mit verschiedenen Lichtspektren unter Berücksichtigung von Belichtungsdauer, Terminen und Sortenunterschieden sowie dem Vergleich von natürlicher...

Strategies for regulation of seed borne diseases in organic farming
Provedor de dados: 21
Autores: Borgen, Anders.
The impact of seed borne diseases on organic cereal production in North-Western Europe is discussed as well as the potential of the possible control measures. It is concluded that it is essential for the organic seed production to put more focus on the control the seed borne diseases. Possible control measures exist, but only a few are used at present. Small seeds are statistically more infected by a number of seed borne diseases than larger seeds. Removal of these seeds by size and gravity separation could be used more frequently. Varieties resistant to the most significant seed borne diseases are available, and improved heat treatment techniques are being developed and are likely to be available for practice in the coming years. Some organic certifying...

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...

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,...

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.

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.

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...

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.

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...

Field observations about the behaviour of codling-moth in Trentino (North-Eastern Italy)
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.

Pflanzenschutz: Biogrundsätze bergen enormes Potenzial
Provedor de dados: 21
Autores: Wyss, Eric.
Der Pflanzenschutz auf Biobetrieben gibt immer wieder Anlass zu heftigen Diskussionen. Soll die Entwicklung natürlicher Spritzmittel weiter vorangetrieben werden? Oder wäre es besser, voll auf Nützlinge zu setzen? Und ist das überhaupt möglich? In dieser Debatte geht es um die Grundsätze des Biolandbaus. Deren Potenzial ist noch lange nicht ausgeschöpft.

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.

Evaluierung deutscher Sommerweizensorten auf Resistenz gegenüber Weizenflugbrand (Ustilago tritici)
Provedor de dados: 21
Autores: Hobert, Mirko; Kopahnke, Doris.
Aufgrund des Verbots der chemischen Beizung stellt der Flugbrand in ökologisch wirtschaftenden Betrieben ein erhebliches Problem dar. Vor diesem Hintergrund hat auch die Resistenzzüchtung gegen diese Krankheit wieder an Bedeutung gewonnen. Ziel dieses im Rahmen des „Bundesprogramm Ökologischer Landbau“ geförderten Projektes ist daher die Identifikation von Resistenzunterschieden im aktuellen Sommerweizensortiment als Basis für eine direkte Nutzung dieser Sorten im ökologischen Anbau bzw. als Ausgangspunkt für eine gezielte Resistenzzüchtung..

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...

Proteomics in the backyard: 2DE based comparison of vegetables grown at conventional farming conditions and organic farming conditions
Provedor de dados: 21
Autores: Nawrocki, Arkadiusz; Thorup-Kristensen, Kristian; Nørregaard Jensen, Ole.
We used 2D electrophoresis and mass spectrometry to compare two organic farming systems with conventional farming of cabbage and carrot. For both vegetable proteomes we observed differential responses that depended on farming conditions. We detected significant protein abundance changes in a series of metabolic processes including glycolysis and protein synthesis. This study provides a framework for detailed molecular analysis of vegetables in large scale field studies and the influence of environmental conditions on plant growth.

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...

Sædskiftesygdomme i frøbælgplanter holdes traditionelt nede med flere dyrkningsfrie år mellem samme art. I FØJO-projektet GRAINLEG, der er et samarbejde mellem DJF Flakkebjerg, KVL og Toft Planteforædling, arbejder vi med at forbedre resistensen overfor jordbårne sygdomme, primært i ært og lupin. Vi søger at identificere resistent materiale til anvendelse i forædling og arbejder med at udvikle metoder, der bl.a. kan anvendes i sortsafprøvningen til test af resistens mod ærterodråd (Aphanomyces euteiches) samt Fusarium i ært og Fusarium rodråd- og visnesyge i lupin.   Gentagen lupindyrkning kan medføre opformering af jordbårne patogener, ofte Fusarium spp., der resulterer i rodråd og visnesyge (lupintræt jord). Såfremt lupin skal vinde indpas som...

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...

In a field experiment conducted over two growing seasons, the effectiveness and phytotoxicity of inorganic fungicides such as sulphur, lime sulphur, copper, silicon and Armicarb (a new formulation of potassium bicarbonate) was compared with water for the control of primary apple scab infections in Belgium on high, medium and low scab-susceptible cultivars (cvs. ‘Pinova’, ‘Pirouette’ and ‘Reinette des Capucins’, respectively). In order to drastically reduce the amount of fungicide applied in the orchard, two approaches were used: (i) a strategy involving spraying during the infection process, just before  conditions for infection had been fulfilled according to the RIMpro software warning system; and (ii) a tunnel sprayer machine for treatment applications....

Etudes de la résistance de différents cépages au mildiou et à la pourriture grise
Provedor de dados: 21
Les mécanismes de résistance des plantes sont multiples. La vigne présente globalement 2 systèmes de résistance aux parasites : un système constitutif, des composés des baies sont inhibiteurs de la croissance ou d'enzymes fongiques et un système induit par les parasites et aboutissant à la synthèse de phytoalexines, à des processus de lignification, à la synthèse de callose. L'analyse des processus d'induction de ces substances présente un intérêt particulier. Ainsi par exemple, les exsudats protéiques et polysaccharidiques de Botrytis cinerea sont capables d'induire la synthèse de stilbènes. La présence de zoospores du mildiou à la surface de feuille de vigne peuvent déclencher des réaction d'hypersensibilité chez des cépages résistants bien que la nature...

Impediments to plant health in table grape production in southeastern France
Provedor de dados: 21
Autores: REYNAUD, C.
At the La Tapy Experimental Station in southeastern France, a plot of table grapes is managed according to the principles of organic farming in order to study potential technical impediments of this growing system compared to another plot that is managed according to the principles of sustainable agriculture. Muscat de Hambourg, the variety common to these two plots, is used as a reference for the different observations. Results are primarily related to the impact of pest management efficiency on vine quality. The qualitative requirement that powdery mildew be absent on table grapes is difficult to fulfil in the case of organic farming, even with several different treatments and frequent applications. Botrytis management is related to climatic conditions;...

Biological control of the cherry fruit fly, Rhagoletis cerasi L. (Diptera, Tephriti-dae) by use of entomopathogenic nematodes: first experiences towards practi-cal implementation.
Provedor de dados: 21
Autores: Herz, Annette; Köppler, Kirsten; Vogt, Heidrun; Elias, Ellen; Katz, Peter; Peters, Arne.
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 appli-cation 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 ex-pectations. 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 chal-lenge. To obtain basic data, we recorded the phenology of infestation...

The currently used downy mildew control strategies in vitis vinifera in Switzerland are based on the use of acidified clay products combined with copper and sulphur.   Data from 1997-2003 show that acidified clay products are a valuable alternative to control downy mil-dew of grapevine in conditions of medium rain fall, good spray timing and with a good application tech-nique. The limits of these products show under heavy rain conditions and when there is high disease pressure.

Phosphorige Säure und Salicylsäure – eine Alternative zu der Anwendung von Kupfer im ökologischen Weinbau?
Provedor de dados: 21

Sowohl bei Salicylsäure als Naturstoff als auch bei Phosphoriger Säure als anorganischer Substanz mit relativ günstigem Umweltverhalten und geringer Toxizität wäre ein Antrag auf Aufnahme in den Anhang 2 der EU-Verordnung 2092/91 nicht aussichtslos. Phosphorige Säure hat den Vorteil, dass der Abbau relativ klar und eindeutig ist (zu Phosphat, einem Pflanzennährstoff).    In der Praxis dürfte die Anwendung von Salicylsaeure alleine aufgrund des geringen Effekts uninteressant sein. In Frage kommt allenfalls ein Zusatz zu anderen Stoffen während der Hauptwachstumsphase.

In den vergangenen 15 bis 20 Jahren hat der Öko-Landbau erhebliche Anstrengungen sowohl bei der Suche nach Kupferalternativen im Pflanzenschutz als auch bei der Minimierung der eingesetzten Kupfermengen unternommen. Allerdings sind bislang und in naher Zukunft keine Präparate oder Verfahren in Sicht, die einen annährend gleichwertigen Ersatz für Kupfer darstellen könnten. Dabei ist darauf hinzuweisen, dass ein gleichwertiger Ersatz nicht durch einen einzelnen Wirkstoff zu schaffen ist, wenn nicht ausgeschlossen werden kann, dass die betreffenden Schaderreger innerhalb kurzer Zeit Resistenzen gegenüber einem solchen Wirkstoff bilden. Unbenommen von allen Schwierigkeiten muss aber die Erforschung von Kupferersatzstoffen und -verfahren forciert werden.  In...

Removal of bunt spores from wheat seed lots by brush cleaning
Provedor de dados: 21
Autores: Borgen, Anders.
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...

Aufgrund der geringen Erträge, die im ökologischen Apfelanbau erzielt werden, kam die Frage auf, was die Gründe dafür sein könnten. In den Diskussionen wird oftmals auf den schlechten Zustand der Apfelbäume hingewiesen. Die Bäume würden einen gestressten Eindruck machen. Als Ursache werden meist aggressive Pflanzenschutzmittel und ungenügende Ernährungszustände in den wichtigen Entwicklungsphasen genannt. Voruntersuchungen zu diesem Versuch, hinsichtlich der Blütequalität, wiesen darauf hin, dass es im ökologischen Apfelanbau um die Blütenqualität nicht zum Besten zu stehen scheint.

Strawberry breeding for disease resistance in Dresden
Provedor de dados: 21
Autores: Olbricht, K.; Hanke, M.-V.
Verticillium resistance is one of the most important breeding goals in strawberry resistance  breeding at Dresden-Pillnitz. Resistance evaluation of cultivars, advanced selections and  seedlings is realized under natural conditions at a provocation field and by artificial  inoculation in the greenhouse. Introgression of Fragaria chiloensis L. (Miller) into Fragaria  ×ananassa Duch. resulted in highly tolerant breeding selections. After back-crossing with  cultivars of F. ×ananassa first genotypes were selected which can be evaluated in  experimental cultivar trials at different locations in Germany.

Approaches to pest management in organic agriculture: a case study in European apple orchards
Provedor de dados: 21
Autores: Wyss, Eric; Luka, Henryk; Pfiffner, Lukas; Schlatter, Christian; Gabriela, Uehlinger; Daniel, Claudia.
Although the European organic agriculture movement was founded by Rudolf Steiner and Hans Mueller in the years between 1924 and 1940, it was not until the 1980s that pest management researchers began to develop strategies to control pests in organic systems. Today, insect pest management in organic agriculture involves the adoption of scientificallybased and ecologically sound strategies as specified by international and national organic production standards. These include a ban on synthetic insecticides and, more recently, on genetically modified organisms (GMOs). The first phase of an insect pest management program for organic systems is the adoption of cultural practices including diverse crop rotation, enhancement of soil quality by incorporation of...

Biological control of Thrips tabaci in the field – possibilities and practical limits
Provedor de dados: 21
Autores: Jung, Kerstin.
Field trials against Thrips tabaci, an economically important pest insect, were conducted in 2003 at four different sites in Germany. The effect of the combined use of entomopathogenic nematodes and fungi on thrips should be investigated, in comparison to the effect of either pathogen alone. Commercially available products, Mycotal® (Koppert NL), PreFeRal® (Biobest BE), Naturalis L® (Intrachem IT), Nemaplus® and Nemagreen® (both E-Nema DE), were used. The trials were performed in onion, leek and chives, according to the EPPO guideline PP 1/85(3). Perfekthion® was used as chemical standard in onion. In leek, Spruzit® and Neudosan® were applied alternately. No chemical standard was applied in chives. The biocontrol products were applied either alone or in a...

Development of the FBC model to estimate the nitrogen available from fertility -building crops in organic rotations
Provedor de dados: 21
Autores: Cuttle, S P.
The FBC (Fertility Building Crops) model has been developed as a planning tool to provide organic farmers with information about how much nitrogen will be available in the soil at different stages following the ley phase of the rotation. It predicts the likely crop yields under this level of nitrogen supply and provides an estimate of how much nitrogen will be lost by leaching and denitrification so that if necessary the grower can examine the effects of modifying the rotation to improve the efficiency of nitrogen use and minimise losses. The model is easy to use and requires only the sort of information that is readily available to commercial growers. Although it appears to provide realistic simulations of a range of crop rotations and conditions, it has...

Resistance management in Vf apple scab resistant organic apple orchards
Provedor de dados: 21
Autores: Trapman, Marc.
Modern Vf scab resistant apple varieties open the way for organic growers to lower fungicide input,  higher yields, better skin quality, more biological control for mites and insect pests and better consumer acceptance of their management practices. Manny examples in the past years have shown however that the Vf resis-tance can be easily overcome by local scab populations in north-western Europe. Discussions during the meetings of the IOBC working group Diseases in Orchards in 2000 in Fontevraud (France) and in 2003 in Lindau (Germany) lead to a set of management practises necessary to prevent gene-fulx, and selection to-wards Vf virulence in the local apple scab populations.  Eleven orchards of the Vf resistant apple variety Santana that where planted...

Influence of plastic cover on fruit-quality and monilia laxa infestations with organically produced apricots
Provedor de dados: 21
Autores: Wurm, L.; Urschler, W.
In the years 2005 to 2007 a plastic cover was tested in a testing area planted with  apricots and operated according to the regulations for organic production.  Compared to the untreated control, fruit below the plastic cover showed decreased  coloration. Monilia laxa infestations below the plastic cover could not be fully  prevented, but were reduced considerably also by copper applications during  flowering in 2007. Yield of the variant treated with copper, however, remained below  average.  Losses due to rot during storage were smallest with the covered variant.

Marktäckning med plast i samband med sådd av radodlade grödor
Provedor de dados: 21
Problemet med ogräs i radsådda grödor är störst kring själva plantorna i raden. I ekologisk odling uppgår arbetsinsatsen för ogräsrensning till cirka 150 timmar/ha i sockerbetor och 300 timmar/ha i morötter. En fortsatt utveckling av ekologisk odling kräver nya metoder för kontroll av ogräsen med en radikalt minskad insats av arbetskostnader. Det danska företaget Holmgaard Innovation har tagit fram en maskin för plasttäckning av raden i samband med sådd av t.ex. sockerbetor. I några mindre undersökningar har utrustningen visat sig fungera så bra att det kan innebära ett genombrott för möjligheten att bekämpa ogräs utan insats av herbicider. Emellertid saknas fortfarande en del grundkunskaper om utrustningens förmåga att kontrollera ogräs, effekter på...

Control of wireworms in organic potato cultivation
Provedor de dados: 21
Autores: Alföldi, Thomas.
Wireworms are a common pest in organic potato crops. They are persistent and tough and so far, there are only indirect measures to control them.   In the video, Giselher Grabenweger (Agroscope) provides an overview of approved methods to control the worms such as crop rotation and tillage. He also explains why potato varieties containing a lot of starch are less affected by wireworms.  In addition to the indirect measures, Agroscope (together with Swiss and German partners) developed specific organic control options. As an enemy of wireworms the researchers found insecticidal fungi of the genus Metarhizium. In meadows, they observed a natural control of wireworms achieved by these soil fungi. The institute now tries to develop a method to apply the fungus...

ProEcoWine: Development of a Novel Plant Protection Product to Replace Copper in Organic Viticulture
Provedor de dados: 21
Autores: Bilbao, Jennifer; Tseng, Eileen; Fuerst, Manfred; Erb-Brinkmann, Maike; Schmid-Staiger, Ulrike; Ördög, Vince; Egner, Siegfried.
Fungi like downy mildew reduce wine yield and impair wine quality. In conventional as well as organic viticulture, grape growers usually apply copper for preventing these fungal diseases. In the ProEcoWine project funded by the EC, on behalf of five companies, the Fraunhofer IGB, the University of West Hungary and Laboratoire PHENOBIO develop a novel bio-plant protection product to replace copper fungicides. To achieve this, microalgal strains with antifungal properties have been cultivated to be further processed into a plant protection product enriched with micronutrients. Strains with the most efficient control (more than 90%) over downy mildew and Botrytis have been identified and selected for validation in greenhouse and field experiments, while...

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 num-ber 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 diame-ters, 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 for...

Disease suppression of potting mixes amended with composted biowaste
Provedor de dados: 21
Autores: Blok, Wim J.; Termorshuizen, Aad J.; Coenen, Trudie G.C.; de Wilde, Vinnie; Veeken, Adrie H.M.
Peat mining destroys valuable nature areas and contributes to the greenhouse effect. This warrants the search for alternatives for peat in potting mixes. Composted biowaste could provide such an alternative. An additional advantage of (partially) replacing peat by compost is the increased disease suppressiveness. In this study, nine commercial composted biowastes were tested for disease suppressiveness using the pathosystems Pythium ultimum-cucumber, Phytophthora cinnamomi-lupin and Rhizoctonia solani-carrot. Increased disease suppression was found in compost-amended potting mixes for all three pathosystems. The level of disease suppression ranged from slight stimulation of disease to strong suppression. Suppressiveness against one disease was not well...

Einfluss der Grünlandnutzung auf die PPO-Aktivität in Rotklee
Provedor de dados: 21
Autores: Eickler, Birgit; Gierus, Martin; Taube, Friedhelm.
Several studies show that polyphenol oxidase (PPO) in red clover reduces proteolysis and increases nitrogen use efficiency of the ruminant, but not much is known about factors affecting PPO activity in red clover plants. PPO activity was analysed in red clover plants from legume-grass mixtures subjected to three different management systems. The cutting frequency (3 or 5 cuts) caused only minor differences in PPO activity, whereas a significant increase in PPO activity could be proved for the rota-tional grazing system (RG), compared to the simulated grazing system (SG, 5 cuts) with equal use frequency. Results indicate a metabolic adaptation of the red clover plants due to the grazing process itself, leading to a control factor which has to be considered...

Autores: Ryu, Kyoung Yul; Jee, Hyeong-Jin; Choi, Du-Hoi; Kim, Jeom-Soon; Landeo, Juan A.; Cho, Hyun-Mook.
Incidence and progress of potato late blight largely depends on susceptibility of the host in organic farming cultivation. In susceptible hosts, the disease completely destroys whole leaves within two weeks in organic farming fields. However, potato leaves of 14 quantitative resistance hosts remained healthy for 5 weeks after the first symptom appearance in the susceptible host. Area under disease progress curve (AUDPC) of quantitative resistance host ranged from 37.5 to 112.5 and slowly expanded compared with that of susceptible host. On detached leaves assay, seven clones of quantitative resistance host did not produce any sporangia against three isolates collected from different areas in Korea.

Autumn acaricide applications as a new strategy 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 Eriophyes pyri (Pagenstecher) causes severe damage to pear leaves and fruits. As mites are well sheltered from exposure to plant protection agents during summer and acaricide efﬁcacy is reduced when temperatures are low in early spring, autumn acaricide applications were evaluated to control mites as they migrate to their hibernation sites. Post-harvest sulphur and mineral oil treatments were applied in September 2003 and mites were monitored in the following spring. Only the sulphur treated trees were virtually free of blisters. Sulphur treatments showed an efﬁcacy of 95.3% (one application) to 99.6% (three applications), whereas, mineral oil treatments only had an efﬁcacy of 12.8% (one application) to 69.6% (three...

The olive tree finds suitable conditions for growing well in the Mediterranean basin. Besides, olives and olive oil play an increasingly important nutritional role in Mediterranean countries and are an essential part of what is widely known as “Mediterranean diet”. Unfortunately one of the most injurious pests is olive fly (Bactrocera oleae). Of African origin, this fruit fly is the key pest of olive throughout the Mediterranean Basin and the Middle East. The olive organic production is developing in order to save the environment and to obtain a safe product. One of the most difficult challenges for conformity of the organic method to Reg. CEE 2092/91 is plant protection. Various experimental tests on the biological control of the olive fruit fly have...

Fusarium graminearum (FG) is the most prevalent Fusarium Head Blight (FHB)  fungus in Switzerland. In conventional agriculture, fungicides are used to reduce the  risk of FHB infection and mycotoxin contamination of wheat. As an alternative for  organic wheat production, we examined plant-based products that showed antifungal  effects from our previous late blight field trials. In bioassays, the effect of these  antifungal plant preparations (APP) was screened against FG. In 2006 and 2008, the  most active APP, Rheum palmatum, Frangula alnus and preparations of Galla  chinensis as well as a plant substance (PSX), were used as FHB control agents in  field trials with artificial FG infections. In both years, FG incidence and deoxynivalenol  content were...

On-farm influence of production patterns on total polyphenol content in peach
Provedor de dados: 21
Autores: Fauriel, J.; Bellon, S.; Plenet, D.; Amiot, M.- J.
Peach production in France is constantly confronted with marketing problems due to a decrease in fruit consumption and increasing competition with neighbouring Mediterranean countries. The production of higher quality products using production methods such as organic farming (OF) appears to be a tangible way of differentiating and enhancing peach production. To test this hypothesis, an on-farm study was conducted in one of the major production areas in South-eastern France. Focussing on the peach cultivar, cv. Spring Lady®, paired comparisons were conducted between plots in OF and conventional farming (CF). Farmers' practices were identified and checked against crop measurements and performances (yield, sugar content, size classes) in 2004 (12 plots) and...

Designing and testing crop rotations for organic farming. Proceedings from an international workshop
Provedor de dados: 21
Organic farming aims at establishing stable and harmonic farming systems, which integrate livestock and crop production. No industrial fertilisers, pesticides or growth regulators are used. The nutrient management is based on the use of animal manure, green manure, crop residues and on nitrogen fixation by legumes. Weeds, pests and diseases are controlled through the use of versatile crop rotations, mechanical weed control and a proper choice of varieties.     The multifunctional crop rotation is thus a key component in organic farming. The design of these crop rotations is a major challenge for farmers as well as for agronomic research.     The different aspects of crop rotations have been investigated by a range of methods, including long-term trials,...

Assessing the sustainability of a stockless arable rotation (OF0318)
Provedor de dados: 21
Autores: Cormack, William.
The majority of organic conversions have been on upland grass-based livestock farms resulting in a shortage of UK-grown cereals and pulses. Across northern Europe, conventional agriculture has developed a specialised structure with many areas having no livestock, or knowledge or facilities to support livestock. Sustainable organic production on these farms has particular challenges for nutrient supply, for the management of weeds, pests and diseases and for economically viability.    This report covers a three and a half year period (four crop harvests) of a longer-term programme of work, which began in 1990. The overall objective was to identify and overcome factors limiting the sustainability of a stockless arable rotation. Specific objectives were to 1)...

Use of rock dust against the rape pollen beetle
Provedor de dados: 21
Autores: Daniel, Claudia; Conder, Malgorzata; Weidmann, Gilles.
Through the use of rock dust at the beginning of the bud development, the infestation by the rapeseed beetle can be reduced by an average of one third. In the treated area the pods per square meter increased by up to a quarter, thereby increasing the yield in treated areas by around 25 %.  Practical recommendation  • Optimal time of treatment: The rape pollen beetles enter the fields at a temperature of 15 °C. Therefore a first treatment with rock dust is appropriate as soon as this threshold has been reached and the buds become visible between the leaves and will be reached by the spray liquid (BBCH 52).  • Note: Pollen beetle infestation is supported by late blooming, frequent rapeseed cultivation and cultivation close to woodland.  • A second treatment...

Kupferminimierungsstrategien für den ökologischen Kartoffelanbau
Provedor de dados: 21
Autores: Nechwatal, Jan; Zellner, Michael.
Im Mittelpunkt dieses BLE-geförderten Projekts steht die Regulierung der Kraut- und Knollenfäule (Phytophthora infestans) im ökologischen Kartoffelbau. Ziel ist es, Phytophthora-Infektionen zu vermeiden bzw. soweit zeitlich hinauszuzögern, dass eine direkte Behandlung des Pathogens in Häufigkeit und Mitteleinsatz reduziert werden kann. Ausgangspunkt für den Ansatz ist die Erkenntnis, dass die Phytophthora-Infektion bei Kartoffeln meistens von latent befallenem Pflanzgut ausgeht. Es werden Maßnahmen des Pflanzenschutzes entwickelt und geprüft, die diese latente Vorbelastung reduzieren und die Widerstandsfähigkeit der Kartoffel erhöhen sollen. Durch die Testung von kupferfreien Präparaten auf ihre Wirkung gegen P. infestans sollen Alternativen oder...

Aspekte der Strohmulchanwendung im ökologischen Kartoffelanbau – II.Wirkung auf Potato Virus Y, Leptinotarsa  decemlineata und Knollenertrag
Provedor de dados: 21
Autores: Döring, Thomas F.; Heimbach, Udo; Thieme, Thomas; Saucke, Helmut.
In Praxisversuchen wurde über drei Jahre der Einfluss von Strohmulch auf das Auftreten von PVY (Potato virus Y), den Befall mit dem Kartoffelkäfer (Leptinotarsa decemlineata) und den Knollenertrag in ökologisch angebauten Kartoffeln untersucht. Strohmulch führte in drei von 17 Experimenten zu einer signifikanten Reduktion von PVY, und in weiteren sieben Versuchen gab es einen nicht-signifikanten Trend zur erminderung von PVY. Der Effekt von Strohmulch auf PVY scheint vom allgemeinen Infektionsniveau abzuhängen, welches je nach Jahr, Standort und Sorte unterschiedlich war. So gab es in den Jahren 2002 und 2004 bei allgemein hohem Infektionsdruck eine konsistente PVY-Verminderung. Im Gegensatz dazu konnte im Jahr 2003, bei nur sehr geringem Infektionsdruck,...

Ny viden om "Topazplet" - et problem i usprøjtede æbler
Provedor de dados: 21
Autores: Korsgaard, Maren; Lund, Ole Søgaard.
Forbrugere ønsker ikke plettede æbler, derfor gør frugtavlere meget for at holde æbler pletfrie. De mest kendte pletter er skurvpletter. De kan forebygges dels ved at plante en skurv-robust sort og dels ved at sprøjte med svovl. En del økologiske frugtavlere vælger at dyrke frugten helt usprøjtet og satser derfor på de æblesorter, der er robuste.

Basic results in biological control of the European Cherry Fruit Fly Rhagoletis cerasi L. (Diptera: Tephritidae) with entomopathogenic nematodes
Provedor de dados: 21
Autores: Köppler, Kirsten; Peters, Arne; Vogt, Heidrun.
In 2002 and 2003, within the ‚Bundesprogramm Ökologischer Landbau’, initial experiments to control  the European cherry fruit fly Rhagoletis cerasi were carried out under laboratory, semi-field and  field conditions with several entomopathogenic nematode species and strains. In the laboratory the  efficacy of nematodes against R. cerasi larvae, pupae and adults was examined. To characterize  the controlling potential, different nematode dosages, exposure temperatures and substrates were  tested in cell wells, petri dishes and plastic boxes. In the semi-field experiments plastic fruit boxes,  filled with soil, were used. In the field tests R. cerasi-larvae and nematodes were released in defined  areas in a cherry orchard of the institute. For evaluation of...

Kaliumbicarbonat als möglicher Schwefelersatz im geschützten  Gemüsebau
Provedor de dados: 21
Autores: Koller, Martin.
The effect of the potassium bicarbonate product «Armicarb» was tested against powdery  mildew on tomato, cucumber melon, rosemary, sage and corn salad. The  disease reducing effect of potassium bicarbonate was comparable to sulphur for most  of the tested crops. With protective applications the efficacy was higher than 90 %.  However in melon were powdery mildew was present before the first spraying, the  efficacy was only 74 %. Compared to plant oils or extracts (such as fennel oil, tea tree  oil and lecithin) potassium bicarbonate has shown the same or better efficacy. In our  experiments we found no phytotoxicity caused by the potassium bicarbonate product  Armicarb®.

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...

Vekselvirkning mellem plantesygdomme påvirker sygdomsudviklingen
Provedor de dados: 21
Autores: Vollmer, J.H.; Østergård, H.; Pinnschmidt, H.; Munk, L.
Sygdomme i planter kan være forårsaget af mange forskellige mikroorganismer, og ofte vil der i en enkelt afgrøde og på én plante være flere arter tilstede samtidigt. På trods af denne erfaring har der været tradition for at forske i sygdomme enkeltvis, og betydningen på det totale sygdomsniveau af vekselvirkninger mellem de enkelte patogener er kun blevet studeret i begrænset omfang. Her beskrives vekselvirkningen mellem sygdommene bladplet og skoldplet på byg i markforsøg.

Untersuchungen zum Einsatz von Pflanzenstärkungsmitteln im ökologischen Futtererbsenanbau
Provedor de dados: 21
Autores: Schleuß, Dr. Uwe; Böhm, Dr. Herwart; Loges, Dr. Ralf.
There is a great requirement for cultivation of grain legumes (e.g. peas) in organic farming systems (protein supply for animals, biological nitrogen fixation, previous crop effects). The occurrence of pests and diseases, e.g. Acyrthosiphon pisum, leads to strong yield losses and yield fluctuations. In organic farming systems the use of plant protection products is strongly limited. Plant strengthening products are compatible to this kind of land use and enhance the resistance of plants to harmful organisms. Field trials with some selected plant strengthening products achieve small yield growth under North-German site and climatic conditions, but rarely it is possible to produce statistical evidence. At low up to medium level of disease attack they show...

Autores: Govasmark, Espen.
To obtain a general picture of the herbage zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), molybdenum (Mo), cobalt (Co) and selenium (Se) concentrations on organic livestock farms, we analysed soil (2001) and herbage (2001 and 2002) samples from 28 farms from four regions in Norway. We analysed animal blood plasma Cu, B12 (Co), α- and γ-tocopherol (vitamin E) and whole blood Se to investigate if the farms feeding practice met the dietary need of Cu, Co, Se and vitamin E in animals.     The first cut herbage median (10th-90th percentile) Zn, Fe, Mn, Cu, Mo, Co and Se concentrations were 19 (14-34), 50 (36-88), 34 (22-86), 5.3 (3.9-6.8), 1.5 (0.6-4.8), &lt;0.05 (&lt;0.05-0.08) and &lt;0.01 (&lt;0.01-0.03) mg kg-1 DM, respectively.

The role of intercropping on insects diversity in dryland field crops in a Mediterranean site
Provedor de dados: 21
Autores: Caballero, Berta; Romero, Albert; Perez, Nicolas; Ventura, Daniel; Chamorro, Lourdes; Goula, Marta; Sans, F.Xavier.
This work aims to evaluate the effect of crop type and density on insects’ community in the Mediterranean re-gion. In winter of 2004, four 35m x 10m blocks (replicates) were delimited and 24 equidistant 2m x 3m plots were marked. Seven crop types (barley, vetch, turnip, barley-vetch, barley-turnip, vetch-turnip and barley-vetch-turnip) at three densities were randomly established within each block. Fifteen crop shoots per plot were randomly collected in May to evaluate insect’s abundance and diversity. Our results suggest that inter-crop has a positive effect on abundance of most exam-ined groups of insects and diversity, specifically when vetch is incorporated in the mixture. Changes in abun-dance of aphids, trips and ants are also discussed connected...

Autores: Tamm, Lucius; Bruns, Christian; Leifert, Carlo; Fuchs, Jacques G.; Thürig, Barbara; Specht, Nicole; Fliessbach, Andreas.
Soil management practices are targeted to provide adequate crop nutrition and to ensure durable soil fertility and to avoid negative environmental impacts. Soil management also aims to reduce pest and disease pressure on crops. Organic farming is believed to increase soil suppressiveness towards soil-borne diseases as well aerial diseases. In this paper we will discuss the potential of soil manage-ment as a tool to improve disease suppressiveness in practice.

Autores: Benker, Marianne; Zellner, Michael; Bangemann, Lars-Wilhelm; Kleinhenz, Benno; Bartels, Gerhard.
Die Bekämpfung der Kraut- und Knollenfäule (Phytophthora infestans) stellt im ökologi-schen Kartoffelanbau nach wie vor ein ungelöstes Problem dar. Bisher kann der Befall nur durch Einsatz von kupferhaltigen Pflanzenschutzmitteln reguliert werden. Ziel des For-schungsprojektes ist es, auf Basis der witterungsbedingten Epidemiebewertung durch das neue Prognosemodell ÖKO-SIMPHYT den Einsatz kupferhaltiger Fungizide im ökologi-schen Kartoffelanbau auf das absolut notwendige Maß zu begrenzen. Durch eine Beizung des Pflanzgutes mit Kupferpräparaten soll das Auftreten von Primärbefall reduziert wer-den, um den Epidemiebeginn und somit auch den Spritzstart nach hinten verlagern zu können. Zur Kontrolle des Sekundärbefalls werden Fungizidstrategien erarbeitet, bei...

Weeds are a perpetual challenge in Organic agriculture. However, they serve multiple ecosystem services and a low competitive weed cover can be tolerated. Adding to  this, is the fact that only a few species prove problematic for both the crop and the farmer. The international PRODIVA project researches the effect of crop diversity strategies on the diversity of weed communities, hypothesizing that by increasing the weed diversity, the development of  problematic weeds will mitigated. A preparatory  study was conducted to list the most problematic weed species in spring sown cereals in the countries involved with PRODIVA. For this a literature review was conducted in  all participating countries, collecting local sources including grey literature. This was...

“Integration of plant resistance, cropping practices, and biocontrol agents for enhancing disease management, yield efficiency, and biodiversity in organic European vineyards – VineMan.org” - FINAL PROJECT REPORT
Provedor de dados: 21
Autores: Rossi, Vittorio.
The Project aimed at improving disease control, which is one of the main and most difficult tasks in organic viticulture, integrating plant resistance against pathogens, cropping practices, use of weather-driven disease models, and use of biocontrol agents (BCAs). All these aspects were firstly considered separately in each WP by the competent partners, then efforts were made to develop innovative vineyard management strategies that consider all these aspects.  All plants have an innate immunity against pathogenic fungi and oomycetes that is triggered by pathogen associated molecular patterns (PAMPs). Repeated application of these molecules or their structural analogues can activate and enhance the innate defence response against a following infection by...

The effectiveness of winter treatments with copper or lime sulphur to control Sooty Blotch on apple.
Provedor de dados: 21
Autores: Trapman, Marc; Tamm, Lucius; Fuchs, Jacques G.
In 2002 and 2003 two randomized trials and three “on farm” trials where carried out  to test the hypothesis that a single winter treatment could reduce the primary  inoculum of Sooty Blotch sufficiently to prevent fruit disease during summer.  copperoxychloride (0.2%-0.4%) and lime sulfur (4.0%-5.0%) were applied until run-off  in March shortly before bud break. Assessments of Sooty Blotch incidence and  severity where made immediately after harvest.  The winter treatments with copperoxychloride did reduce disease severity during  summer in one case. The treatments with lime sulfur reduced the disease level in  three sites to some extent. However, winter treatments alone were not nearly as  efficient as summer treatments. Therefore, we see no reason to...

A guide to organic grassland
Provedor de dados: 21
Autores: Philipps, Lois.
Organic farming systems in the UK are traditionally based on ley/arable crop rotations. Up to 70% of the farmed area comprises of mixed grass and legume leys. These leys offer a powerful mechanism for supplying nitrogen through their potential to harvest biologically fixed nitrogen to support both animal production and a subsequent phase of arable cropping.  This bulletin answers some of the common questions about organic grassland management.

Provedor de dados: 21
Autores: Jürgens, H.-U.; Jansen, G.; Kuhlmann, J.
Lupines are used as protein-rich feeding stuff with high quality for the organic farming. Therefore important quality parameters are estimated in different cultivars and breed-ing lines of blue lupins in relation to location. Protein content, amino acid composition, fat and fatty acid composition, as well as antinutritive substances (raffinose oligosac-charides and alkaloids) were often more different between locations than cultivars. The reason for differences in content and composition of the ingredients is caused probably by diverse environmental conditions especially soil acidity (pH-value).

In the absence of effective control measures, the strawberry blossom weevil (Anthonomus rubi) (SBW) and the raspberry beetle (Byturus tomentosus) (RB) cause large (10 - &gt;80%) losses in yield and quality in organically grown raspberry. Attractive lures for both pests were combined into a single multitrap for the economical management of both of these pests at the same time. This is one of the first approaches to pest management of non-lepidopteran insect pests of horticultural crops using semiochemicals in the EU, and probably the first to target multiple species from different insect orders. The aim is to develop optimized lures and cost-effective trap designs for mass trapping and to determine the optimum density and spatial and temporal patterns of...

L. angustifolius genotypes susceptible to Fusarium root rot and wilt can be grown in new lupin land without disease symptoms, however, lupin root rot and wilt pathogens build up during repeated cropping of susceptible lupins in the same field. After four lupin crops symptoms of root rot and wilt began in an inhomogeneous pattern over the field, and after another three lupin crops susceptible lupins are destroyed before flowering homogeneously over the field and caused total crop failure. The dominating pathogens isolated from diseased lupins with root rot and wilt symptoms in this field are in descending order F. oxisporum, F. solani, F. culmorum,  and F. avenaceum, the latter only being isolated from young autumn sown plants.

Erarbeitung von wissenschaftlichen Ansätzen zur biologischen Kontrolle der Rebenperonospora und für Strategien zu deren Regulierung im ökologischen Weinbau
Provedor de dados: 21
Im ökologischen Weinbau sind Alternativen für Kupfer zur Bekämpfung der Rebenperonospora dringend erforderlich. Verfahren zur biologischen Bekämpfung sind erwartungsgemäß dann am erfolgreichsten, wenn sie an einer Schwachstelle des Erregers ansetzen. Zur Charakterisierung von Schwachstellen im Infektionszyklus der Rebenperonospora (Plasmopara viticola) wurden mikroskopische und zellbiologische Untersuchungen durchgeführt. Dabei konnten die einzelnen Phasen des Zyklus dargestellt und ihr zeitlicher Ablauf ermittelt werden. Schwachstellen wurden vor allem während des Infektionsprozess vor dem Eindringen des Erregers in die Pflanze gefunden. In dieser Phase liegen Zoosporen vor, die sehr empfindlich auf natürliche Hemmstoffe reagieren. Die cytologischen...

Based on a field trial, the impact of three different viticultural management strategies on vigour and grapevine physiology of Vitis vinifera cv. Riesling was compared. The vines were planted in 1991 at Geisenheim (Rheingau, Germany) and three different management strategies i.e. integrated (code of good practice), organic (European Union Regulation 834/07 and ECOVIN standard) and biodynamic (European Union Regulation 834/07 and DEMETER standard) were established in 2006.  Even though all treatments received the same level of nutrients and water a decline in vigour, expressed as lateral growth, was observed for the organic and biodynamic treatment during three seasons (2010 to 2012). During dryer conditions (2011) a reduction of physiological activity...

Rübsen (Brassica rapa var. silvestris) als Fangpflanze zur Kontrolle von Schadinsekten in Winterraps
Provedor de dados: 21
Autores: Döring, Alexander; Wedemeyer, Rainer; Saucke, Helmut; Ulber, Bernd.
Previous studies have shown that most of the specialized rape pests prefer turnip rape over oilseed rape. In our studies two trap crop strategies were tested under field conditions in central Germany. In the first trial a turnip rape (Brassica rapa var. silvestris) strip was sown along the edges of the oilseed rape (Brassica napus) main crop. In the second trial a seed mixture of 95% oilseed rape and 5% turnip rape was sown and was compared to oilseed rape in pure crop. In both experiments the turnip rape trap crop was more attractive to cabbage stem flea beetle (Psylliodes chrysocephala) and pollen beetle (Meligethes aeneus) than the oilseed rape. Neither the border strip nor the intercropping was able to reduce the level of infestation of the oilseed...

Presprouting of seed tubers is a measure that is often recommended for organic potato growing. In on-farm field experiments the effect of presprouting was evaluated with respect to virus infection, yield and weed infestation. The effect of presprouting on yield was largely dependent on the year and on the late blight severity. Weeds were not affected significantly by presprouting. In most experiments virus incidence was higher in presprouted potatoes. Presprouting also had a suppressive effect on undesired regrowth after haulm destruction.

Control of the apple sawfly Hoplocampa testudinea Klug in organic fruit growing
Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Maxin, P:; Rank, H.; Bathon, H.; Zebitz, C.P.W.
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 addi-tion of T/S forte and high amounts of water to obtain the best effect. If the conditions for applica-tions are good and the infestation is not too high, the normally recommended...

Autores: Lukas, Kathrin; Innerebner, Gerd; Kelderer, Markus; Finckh, Maria R.; Hohmann, Pierre.
The six products, Armicarb, Vitisan, lime sulphur, Caso, Calce Fiocco and Ulmasud were tested for their ability to control downy mildew (Plasmopara viticola) on grapevine (Vitis vinifera) in order to find effective alternatives to copper, a heavy metal that is commonly used as a fungicide in organic viticulture. Each product was applied to potted grapevines at i) 40°h (degree hours) and ii) 80°h after inoculation (ai) of the pathogen. These so-called stop-sprays were tested on plants that received two different P. viticola inoculum rates. The formulated potassium bicarbonate product Armicarb and lime sulphur reduced disease incidence and severity similar to or better than the copper hydroxide treatment. Armicarb and lime sulphur reduced disease incidence...

The general ecological mechanisms that determine the interactions between availability of re-sources (nutrients, water) and synthesis of defence related secondary metabolites in the plants will be presented. In short, under normal conditions in nature, where growth is limited by a relatively constant availability of nitrogen at a moderate level, plants strike a balance between defence and growth. They use a fraction of resources such as carbohydrate, N and S to reach a genetically determined normal level of defence mechanisms, which will prevent or quickly overcome most types of infections. If the local availability of nitrogen happens to increase (e.g. from decomposition of animal faeces), the growth rate increases, and the balance shifts. The...

Copper replacement in organic viticulture - state of the art in legislation and research
Provedor de dados: 21
Autores: Berkelmann-Löhnertz, Beate.
In European viticulture, downy mildew (Plasmopara viticola (Berk. &amp; Curt.) Berl. &amp; de Toni) is one of the most dangerous diseases affecting grapes, causing significant damage and severe decreases of product quality.  European organic viticulture is predominantly based on copper applications to control this disease. Due to environmental problems incurred by copper applications, the European Commission decided to limit the use of certain copper products in organic viticulture. This should be achieved by the year 2002 (cf. EC 1488/97). Therefore, the Commission recommends testing alternative strategies in downy mildew control in line with EC 2092/91.  In the last decade, specific actions were realized to investigate, apply and support alternative...

Provedor de dados: 21
Autores: Walther, Bernd; Malevez, Jean; Pelz, Hans-Joachim.
Water voles (Arvicola terrestris) and common voles (Microtus arvalis) cause substan-tial damage in organic fruit growing by gnawing at bark and roots of trees. To prevent the immigration of voles into orchards a mechanical drift fence was developed and successfully tested in 2002 and 2003. The effectiveness of the drift fence, consisting of wire mesh reaching 30 cm above the soil surface and up to 30 cm into the ground, was impaired by moles (Talpa europaea) undermining the fence. Voles used these tunnels to immigrate into the protected plots. In a new study supported by “Bund-esprogramm Ökologischer Landbau” and carried out between 2004 and 2006, factors contributing to undermining of drift fences by moles were determined. The results of practical field...

Controlling pollen beetles in Switzerland
Provedor de dados: 21
Autores: Daniel, Claudia.
Meligethes aeneus (pollen beetle) are a threat to oilseed rape. They migrate to the crops during the spring, damaging buds to feed on the pollen and nectar in the buds. In Swiss organic production as well as in Swiss IPM-production the use of insecticides in oilseed rape is prohibited. FiBL is developing an alternative non-insecticidal method to control pollen beetles. During migration, oilseed rape pests use volatile cues (signals given off by plants) to locate their host plants. This project is developing a control strategy for the pollen beetle based on repellent odors. By introducing odors to the field, the beetles find it much harder to locate their host plants. The project started with lab screenings of different essential oils, then, based on the...

Promotion of leaf degradation by earthworms under laboratory conditions
Provedor de dados: 21
Autores: Heijne, Dr. Bart; de Jager, Anton; de Jong, Peter Frans.
Organic materials were applied to leaves from organic apple trees. Then, leaves were fed to earthworms in a laboratory culture. The objective was to select materials which promote leaf degradation by earthworms and consequently reduce the inoculum pressure of apple scab in orchards. Used earthworms were fully grown and consequently no effect of the leaf treatments was found on earthworm weights. However, leaf consumption tended to be increased by addition of amino acids and beet pulp to leaves. For beet pulp, this was especially the case when the dose was increased from 1 to 5 % or when it was freshly applied.

Because of the interdiction of chemical seed treatment, smut resistance is a main demand for cultivation of winter barley in organic farming. A comparison of common high yielding varieties with those chosen particularly with regard to good smut-resistance or tolerance showed no significant differences in field performance under the conditions of organic farming. Main criteria were the yield of grain and the content of protein and most important amino acids for animal nutrition (Cystine, Lysine, Me-thionine, Threonine, Tryptophan). Besides this the degree of shading weeds was estimated by means of measuring leaf areas and lengths of stalks. The leaf area proved to be the main factor. The availability of smut resistant or tolerant varieties out of organic...

Research covered investigation of efficacy of biopreparations in vegetable protection (onion, carrot, parsley, red beet, dill, radish) against fungal diseases. Seeds were coated with a biopreparation formulated on the basis of Trichoderma viride prior to sowing. After a series of experiments it was found that proper technology enables coating with biopreparation. This process should be as short as possible because of the need to maintain enough number of living colony forming units (cfu). Coated seeds may be stored for a period of several months. Microbiological cleanliness of coat components is also of great importance. Biopreparation in coats to some extent limited the occurrence of rot diseases during germination.

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.

Screening of winter barley varieties (Hordeum vulgare) for resistance against loose smut (Ustilago nuda) and covered smut (Ustilago hordei) in Germany
Provedor de dados: 21
Autores: Lorenz, Norbert; Klause, Stefan; Müller, Karl-Josef; Spieß, Hartmut.
Up to now organic farmers depend greatly on conventionally bred and produced varieties of barley. A turning point was set in 2004 by EU regulation No. 1452/2003 restricting the use of conventionally propagated seed and planting material for organic agriculture. Concerning smut fungi in barley, conventional seed producer's attention was rarely directed to plant resistance due to the possibility of chemical seed treatment (controlling the diseases completely). A main problem for organic seed producers is that organically produced seeds have to fulfil the same regular phytosanitary requirements like conventionally produced seeds. For the production of certified seeds not more than five ears infected with Ustilago hordei (Uh) and/or U. nuda (Un) are allowed on...

Report on quality characteristics of varieties to be used in organic farming
Provedor de dados: 21
Autores: Micheloni, C.; Plakolm, G.
The key questions which will be addressed in this report are:  • Which variety characteristics are important for organic farming and are they different from conventional farmers demand?  • What is an “appropriate“ variety for organic farming?  • Is the actual variety offer available to organic farmers satisfactory? Is it different per crops type and/or per geographic area?  • How should variety trials be conducted in order to supply the information needed by organic operators?  The main answers may be synthesized as follows:  Characteristics of varieties to be used in organic farming are partly different from the ones requested in conventional farming. Main differences are related to yield stability, processing properties and root-system development;  The...

Auswirkungen von Fusarium solani f. sp pisi, Fusarium avenaceum und Mycosphaerella pinodes auf Sommererbsen im Topfversuch
Provedor de dados: 21
Autores: Bacanovic, Jelena; Šišić, Adnan; Bruns, Christian; Finckh, Maria R.
Foot rot is an important limiting factor in pea production in Germany (Pflughöft, 2008). The disease is caused by a pathogen complex consisting of Ascochyta complex pathogens (Mycospharella pinodes, Phoma medicaginis and Ascochyta pisi) and Fusarium spp. However, little is known about the specificity of single pathogens of the complex and their impact on plant performance. In order to address this problem pot experiments with five isolates each of Fusarium solani f.sp pisi, Fusarium avenaceum and Mycosphaerella pinodes were carried out in controlled conditions. Three weeks after sowing and inoculation disease symptoms were assessed and plant growth parameters measured. All pathogens caused root discoloration and development of disease symptoms on pea...

Combining 1,4-dimethoxybenzene, the major flower volatile of wild strawberry Fragaria vesca, with the aggregation pheromone of the strawberry blossom weevil Anthonomus rubi improves attraction
Provedor de dados: 21
Autores: Wibe, Atle; Borg-Karlson, Anna-Karin; Cross, Jerry; Bichao, Helena; Fountain, Michelle; Liblikas, Ilme; Sigsgaard, Lene.
The aggregation pheromone of strawberry blossom weevil [Anthonomus rubi Herbst (Col.: Curculionidae)], a 1:4:1 blend of Grandlure I, II and racemic lavadulol, has been available for pest monitoring for several years but shows low attractancy. Attempts to control A. rubi using the pheromone alone were also unsuccessful. This paper reports the finding that addition of the major flower volatile from wild strawberry flowers [Fragaria vesca L. (Rosaceae)], 1,4-dimethoxybenzene (comprising 98% of the volatiles emitted from wild strawberry flowers), to the aggregation pheromone increased trap catches by over two fold compared to the pheromone alone. There was no significant difference between the response of overwintered or summer emerged adults. Field trials in...

Biologische Bekämpfung ausgewählter Schadinsekten mit Hilfe von Pilzen und durch Förderung der natürlichen Feinde
Provedor de dados: 21
Insektenpathogene Pilze sind wichtige natürliche Regulatoren von Insektenpopulationen. Bei bodenbewohnenden Arten oder Entwicklungsstadien sind es in erster Linie Hyphomyceten. Für die Anwendung zur Schädlingsregulierung eignen sich besonders Beauveria brongniartii und Metarhizium anisopliae. Ersterer ist an der FAL als Mycoinsektizid entwickelt worden und ist zur Bekämpfung von Engerlingen des Maikäfers im Handel. Die Erfahrungen haben gezeigt, dass das Potenzial dieses Produktes noch nicht ausgeschöpft und Verbesserungen möglich sind. Andere Bodenschädlinge, besonders Drahtwürmer, verursachen zunehmende Probleme, die möglicherweise mit dem Pilz Metarhizium anisopliae gelöst werden können.

Autores: Clerc, Maurice; Taramarcaz, Josy.
Un essai de rotation culturale en grandes cultures bio sans bétail est mené sur la ferme pilote de Mapraz à Thônex/GE depuis l’automne 1999. Une première période d’essai de 6 ans comparant deux procédés (avec et sans fumure) sur une même rotation de 1999 à 2005 a permis de démontrer le potentiel et les risques. Les rendements moyens n’ont pas été influencés par la fumure (compost de déchets verts) et sont restés stables d’année en année. Ils ont été équivalents aux références, sauf pour la féverole, le trèfle violet et le blé après tournesol, pour lesquels ils ont été inférieurs aux références. Le chardon des champs et le vulpin des champs ont provoqué des limitations de rendement (le rapport intermédiaire 2000-2005 est disponible sur :...

Lutte contre les gastéropodes : tests de produits biologiques alternatifs au métaldéhyde : compte-rendu d'essai 2006
Provedor de dados: 21
Autores: Lambion, Jérôme; Mounier, Jean-Michel.
Cet essai a pour objectif de définir si l'utilisation de doses réduites d'orthophosphate (limitant ainsi les coûts) limite l'efficacité du produit de façon rédhibitoire, pour différents niveaux de populations d'escargots.  Dans des conditions optimales (aucun lessivage), l'orthophosphate de fer a montré une bonne efficacité. Malgré un effet choc moins bon que le métaldéhyde, les doses de 25 kg/ha et 50 kg/ha permettent une immobilisation comparable au métaldéhyde en piège. L'effet dose est net. Pour une même dose, des effectifs supérieurs entraînent logiquement des taux d'immobilisation inférieurs.  D'après les résultats de ces essais, faire un apport d'orthophosphate à la dose D revient sensiblement à faire 2 apports à la dose D/2 en terme...

Degradation behaviour of potassium K-phosphite in apple trees
Provedor de dados: 21
Autores: Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
Although potassium phosphite is not registered for organic fruit production in Europe, it  has long been regarded as a potential alternative to sulphur- and copper-containing  fungicides. In 2005/2006 a field trial was carried out to verify the presence of residues of  phosphoric acid over time in apples after applications of potassium phosphite at different  time-points. No residues were present on fruits if treatments were applied before flowering,  whereas treatments after flowering, in the summer or in autumn resulted in comparable  residue levels irrespective of the period of application. Residues were eveneven found in  leaves and fruits of the following years, 2006 and 2007.

Pløjefri dyrkning: effekter på jordens frugtbarhed
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.; Heckrath, G.; Jørgensen, M.H.
Interessen for pløjefri dyrkning er steget voldsomt gennem de seneste år. Fokus har primært været på de kortsigtede økonomiske gevinster som følge af mindsket tidsforbrug og lavere maskinomkostninger og i langt mindre grad på de langsigtede gavnlige effekter af pløjefri dyrkning på jordens frugtbarhed. Forskellen er slående i forhold til Nordamerika, hvor den udbredte brug af pløjefri dyrkning i høj grad er båret af et ønske om en langsigtet sikring af jordens frugtbarhed (jfr. betegnelsen ”conservation tillage” anvendt for pløjefri jordbearbejdning. I Nordamerika har man især været optaget af pløjefri dyrkning, som et middel til bekæmpelse af vind- og vanderosion.

«Bien positionner ses traitements au printemps est la clé pour maîtriser la tavelure avec un minimum de phyto », introduit Laurent Jamar, chercheur belge. Il est vrai que, pour pouvoir contaminer une feuille, une fleur ou un fruit, le champignon responsable de la tavelure a besoin de la présence d’un film d’eau pendant un certain laps de temps, variable selon la température : la protection phytosanitaire doit ainsi être ajustée aux conditions pédoclimatiques, définies si possible au niveau du verger. « Pour cela, deux outils sont essentiels : une station météo, qui enregistre les données localement heure par heure, et un modèle de simulation des infections, qui analyse les données météos enregistrées.

Værdien af sygdomsresistens i økologisk dyrket vårbyg
Provedor de dados: 21
Autores: Hovmøller, M.S.; Thomsen, I.; Kristensen, K.; Østergård, H.
Bladsygdomme kan være et væsentligt problem både i konventionel og økologisk dyrkning af vårbyg. Der er gode muligheder for at forebygge bladsygdomme ved korrekt sortsvalg, såfremt man lægger vægt på sortens (eller sortsblandingens) resistensegenskaber. Det er således afgørende at kende sortens resistens mod specielt de sygdomme, som har størst sandsynlighed for, baseret på den enkeltes erfaringer, at kunne blive et problem. Udover sortsegenskaber vil sygdomsniveauet for den enkelte sygdom i den enkelte mark afhænge af det lokale smittetryk i begyndelsen af vækstsæsonen, jordens næringsstofbalance- og frigivelse, mikrobiel aktivitet samt vind og vejr.

Effects of the period of application of K-phosphite on residues on apple fruits
Provedor de dados: 21
Autores: Kelderer, Markus; Matteazzi, Aldo; Casera, Claudio.
K-phosphite is very efficient against several plant diseases. Nevertheless at the moment there is no official  registration in Europe as a plant protection material. In conventional winegrowing K-phosphite is used in  different countries to regulate the main disease ‘Plasmopora viticola’ under the disguise of a foliar fertilizer or  a plant strengthener. In organic apple production only a few fungicides to regulate scab are available. In  addition, copper products are limited by European and national legislations. The discussion about Kphosphite  for organic farming points always at the problem of synthetic residues on the edible parts of the  vegetables. The aim of this field-trial carried out during the season of 2005 was to assess the residues on...

Two seasons (2005/06 and 2006/07) of field experiments which aimed to study the suitability of new and established husked oat varieties, variety mixtures and a husked oat population for organic systems were established at two sites in the west and east of the UK. The ground cover and leaf area indices of the varieties had significant effects on final yields in the 2005/06. Mixtures generally yielded similarly to the means of component varieties but the mixtures in 2005/06 and 2006/07 had 25 % and 18 % less disease, respectively, than the average of the component varieties at one site.

Gegen die mehlige Apfelblattlaus Dysaphis plantaginea wird in der Praxis im Frühjahr bei ein bis zwei Prozent befallener Blütenbüschel behandelt. Die Notwendigkeit dieser tiefen Schadschwelle ist aber wissenschaftlich nicht untersucht und das Potential einer gut funktionierenden Population an natürlichen Blattlausgegenspielern nicht berücksichtigt. In der pestizidfreien Versuchsanlage haben wir die Dynamik der Blattläuse und ihrer Gegenspieler während sieben Jahren erfasst.

Applications of signal transduction and xerophytophysiology by exposing hypocotyls in organic peanut production
Provedor de dados: 21
Autores: Qin, Feifei; Xu, Hui-lian; Takano, Tetsuo.
The AnM practices in peanut production included three steps. The three letters, A, n and M, showed the shapes of the section-cross of the ridge at the three steps of different growth stages of the peanut crop. First, the peanut seeds were sown a little deeper than usual, about 8 cm, in the ridge to induce the extra-elongation of the hypocotyl. When the seeds were sown, the cross-section of the ridge looked like the letter “A”. The second, the hypocotyls elongated more than usual were exposed to light and dry air by removing the soil away around the young seedlings just after the emergence. At this time, the cross-section of the ridge looked like the letter “n”. The third, at the middle growth stages, soils on the both sides of ridge were earthed up to...

Studies on exploiting semiochemicals for pest management in organic farming systems OF0188
Provedor de dados: 21
Autores: Pickett, JA; Wadhams, LJ; Pye, BJ; Smart, LE; Wolfe, M.
This study addresses the extent to which pest management systems can exploit semiochemicals (defined below) in ways acceptable to organic farming, and determines where the science base needs to be expanded to accommodate specific problems arising in an increasing organic farming sector. It considers whether current knowledge of semiochemical release from particular crop plants, herbs and wild plant species could be investigated further in relation to organic farming practice and identifies how strategies of multiple cropping, that exploit known semiochemical interactions, could be applied to key pest problems in organic production. Where such exploitation is not feasible, other strategies using semiochemicals including traps, extracts of natural products...

An extract of Penicillium chrysogenum elicits early defense-related responses and induces resistance in Arabidopsis thaliana independently of known signalling pathways
Provedor de dados: 21
Autores: Thürig, Barbara; Felix, Georg; Binder, Andreas; Boller, Thomas; Tamm, Lucius.
An aqueous extract of the mycelium of Penicillium chrysogenum (further called ‘Pen’ induced early defense-related responses such as an extracellular alkalinisation in cell cultures and ethylene production in leaf slices of numerous mono- and dicotyledon plant species, including Arabidopsis thaliana, tomato, tobacco and rice. The Pen-elicitor was sensitive to protease digestion but insensitive to other enzymes, suggesting that the elicitor-active region is a protein or a peptide. Reversed phase, ion exchange and size exclusion chromatography revealed that the Penelicitor is heterogeneous. This prevented further identification of the elicitor. Pen protected A. thaliana from a broad range of pathogens, including an oomycete (Hyaloperonospora parasitica), two...

Control of the apple sawfly Hoplocampa testudinea Klug in organic fruit growing and possible side effects of control strategies on Aphelinus mali Haldeman and other beneficial insects
Provedor de dados: 21
Autores: J., Kienzle; J., Zimmer; K., Klopp; P., Maxin; K., Yamada; H., Bathon; C.P.W., Zebitz; P., Ternes; H., Vogt.
The effect of Quassia extract on eggs and larvae of the apple sawfly Hoplocampa testudinea  was studied. The efficacy of this extract is mainly due to an oral toxicity to the  neonate sawfly larvae. The main active ingredients, Quassin and Neoquassin, were  tested separately. Wheras Quassin has a considerable efficacy also on older larvae,  Neoquassin is less efficient in this case. While Quassin and Neoquassin are found in  different Quassia sources in varying relations to each other and have different efficacy,  they have to be considered separately in the definition of extract quality by the content of  active ingredients. These findings mean, that the “egg maturity” is not important for application  date. Nevertheless, the application must take place...

Autores: Pommer, G.
Über vier Jahre wurden an vier Standorten Winterweizen und Sommerweizen Sortenversuche am gleichen oder an eng benachbarten Standorten angebaut. Verglichen wurden die arttypischen Erträge und die Backqualität. Der dominierende Einfluss auf die artspezifischen Ertragsdifferenzen ging von der Witterung aus. Eine häufig auftretende frühe Sommertrockenheit hat in acht Fällen die Erträge des Sommerweizens stark vermindert. Auf Standorten mit guten Böden bzw. Vorfrüchten war der Winterweizen überlegen. Nur an einem extremen Standort mit schweren und zur Verdichtung neigenden Böden war der Sommerweizen im Ertrag etwa gleich, hatte jedoch eine bessere Backqualität als der Winterweizen.  In den meisten Fällen verfügte der Sommerweizen, häufig jedoch wegen seiner...

Birch tar oil is an effective mollusc repellent: field and laboratory experiments using Arianta arbustorum (Gastropoda: Helicidae) and Arion lusitanicus (Gastropoda: Arionidae)
Provedor de dados: 21
Autores: Lindqvist, Isa; Lindqvist, Bengt; Tiilikkala, Kari; Hagner, Marleena; Penttinen, Olli-Pekka; Pasanen, Tiina; Setälä, Heikki.
Populations of two molluscs, the land snail Arianta arbustorum and the Iberian slug Arion lusitanicus, have increased substantially in many places in the northern Fennoscandia in recent years. This has resulted in considerable aesthetic and economic damage to plants in home gardens and commercial nurseries. Birch tar oil (BTO), is a new biological plant protection product, and was tested against these molluscs. In this study we examined whether 2 types of BTO, used either alone, mixed together, or mixed with Vaseline®, could be applied as 1) a biological plant protection product for the control of land snails by direct topical spray application, 2) as a repellent against snails when painted on a Perspex® fence, and 3) as a repellent against slugs when...

Field testing of strategies for fire blight control in organic fruit growing
Provedor de dados: 21
Autores: Kunz, S.; Schmitt, A.; Haug, P.
In organic fruit growing effective control strategies are needed to prevent blossom infections by the fire blight pathogen Erwinia amylovora. Many potential control agents are under discussion and have been tested in vitro and in vivo. 19 out of 27 tested preparations showed a high efficacy against E. amylovora in vitro. Nevertheless, on detached apple blossoms only 7 of them led to a symptom reduction by more than 50%. In six field trials conducted according to the EPPO guideline PP1/166(3) BlossomProtect (82%), Myco-sin (65%) and Funguran (58%) had the highest efficiency. In 2006 and 2007, strategies to integrate BlossomProtect in spray schedules of organic apple production have been tested. The use of sulphur or lime-sulphur before or after...

Einsatz von Pheromonfallen zum Monitoring von Schnellkäfern (Agriotes spp.) in Vorfrüchten zu Kartoffeln
Provedor de dados: 21
Autores: Böhm, Dr. agr Herwart; Krause, Tanja.
The infestation of potatoes with wireworms is also in organic farms an increasing problem. The percentage of marketable potatoes is clearly reduced by the grub of wireworms. The grading is much more time-consuming and the produce is sometimes not saleable. In consequence the profitability of potato production is at risk. A monitoring of the occurrence of click beetles (Agriotes spp.) is possible with pheromone traps. First results of the year 2004 showed a very high occurrence of A. lineatus (2148 click beetles per trap) in clover grass (prec-crop to potatoes) on an organically managed farm in Northern Germany. The occurrence of A. obscurus was much lower with 257 click beetles per trap. The experiments should be continued over the next years in...

Autores: Döring, Thomas F.; 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...

Autores: Lenc, Leszek; Sadowski, Czeslaw; Nowacki, Wojciech; Lukanowski, Aleksander.
In 2002-2004, the disease incidences of six potato varieties grown under organic or integrated farm practices were studied. Disease incidences were also investigated with respect to soil fungal populations and the practice of pre-germinating of tubers. Organically grown potatoes had a lower occurrence of sprout rot (Rhizoctonia solani) and common scab (Streptomyces scabies) than potatoes grown in integrated system. More saprophytic species were found in the organic rather than in the integrated system. Pre-germination of potato tubers had positive but minimal effect. There were large differences in disease susceptibility among the potato varieties tested.

Biologiska möjligheter till bekämpning av mykotoxinbildande fusarium
Provedor de dados: 21
Angreppen av Fusarium ökar i svensk växtodling, bland annat beroende på den kemiska bekämpningen av olika svampar som hämmar Fusarium. Det finns idag inga bra kemiska bekämpningsmedel mot Fusarium. Samtidigt ökar intresset för biologisk bekämpning. Målet med denna pilotstudie var att identifiera möjligheterna för biologisk bekämpning av Fusarium i stråsäd genom en enskild mikroorganism med flera verkningssätt, eller en blandning av mikroorganismer med kompletterande verkningssätt. Man studerade såväl befintliga kommersiella preparat som nyisoleringar av antagonister (”fiendeorganismer”). Testerna utfördes huvudsakligen på tre olika Fusariumarter.    Resultaten tyder på att flera av de undersökta mikroorganismerna har en outnyttjad potential som...

Are organically grown apples tastier and healthier? A comparative field study using conventional and alternative methods to measure fruit quality
Provedor de dados: 21
Autores: Weibel, F.P.; Bickel, R.; Leuthold, S.; Alfoeldi, T.
Since 1994 important supermarket chains in Switzerland successfully sell apples from verified organic production. However, in supermarkets customers often ask whether there are, apart from a more environmentally friendly production, objective arguments of inner fruit quality that justify the higher prices of organic apples.     In a field study with the ‘Golden Delicious’ cultivar, we harvested fruits of 5 pairs of organic/integrated fruit farms. The orchards within the pairs were less than 1 km from each other and were similar in micro climate, soil conditions and planting system. Maximum distance between the pairs was 180 km. To measure inner fruit quality we investigated at the beginning and at the end of cold storage (i) standard parameters (firmness,...

La drosophile du cerisier (Drosophila suzukii), qui est arrivée en Europe en 2008 depuis le sud-est de l’Asie, peut provoquer des dégâts considérables. Elle s’attaque à tous les fruits tendres comme les baies, les cerises, les prunes et le raisin. Et de nombreuses plantes sauvages comme le sureau et la viorne obier lui servent de plantes-hôtes. Les dégâts sont principalement causés par les larves qui mangent les fruits de l’intérieur.

True bugs (Hemiptera; Heteroptera) are important pests in fruit production in Norway. In organic fruit production  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 methods are  available against bugs. In this study we have tried a cultural control method (mowing of groundcover) 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...

Erste Freilanduntersuchungen zur Wirkung von Madex plus gegen CpGV-resistente Apfelwicklerpopulationen in Öko-Betrieben
Provedor de dados: 21
Autores: Kienzle, J.; Zebitz, C.P.W.; Zimmer, J.; Volk, F.
In first field tests on codling moth (Cydia pomonella L.) populations proven to be resis-tant against codling moth granulovirus (CpGV) Madex plus, a selectioned CpGV, proved to be rather effective and showed a better efficacy than Madex 3, the standard CpGV-product.    However, it is to consider that high amounts of Madex plus were used (50 ml/ha and m tree height each seven sunny days (a rainy day is considered half a sunny day). Moreover, the risk of development of resistance against this new selection is not clear yet. Thus, even if now a new selection of CpGV is available for the first time, the strategy of codling moth control in organic farming must rely on more components than only CpGV and mating disruption in the future.

Reduction of net photosynthesis after blossom: a possibility to control alternate bearing in organic orchards?
Provedor de dados: 21
Autores: Prantl, Markus; Lardschneider, Ewald; Grapadelli, Luca Corelli; Kelderer, Markus.
Conventional and integrated fruit growers have the possibility to use Carbaryl and  Benzyladenin 2 thinning agents, which allow crop regulation at a relatively late stage (10 –  16 mm of fruit size). At that stage, organic fruit growers can only thin by hand, which is  quite time-consuming. A few surveys show that reducing net photosynthesis after blossom  increases the June drop. This could be an interesting new approach for organic apple  orchards. In 2003 a trial was carried out at the Laimburg Research Station to understand if  application of high amounts of bentonite could achieve that goal. The results were  encouraging, but still not recommendable to practical growers.

Einfluss von Phytophthora infestans auf den Kartoffelertrag in Abhängigkeit von der Nährstoffversorgung und optimierten Kupferapplikationen
Provedor de dados: 21
Autores: Finckh, Maria R.; Schlute-Geldermann, Elmar; Musa, Tomke; Forrer, Hans-Ruedi; Bruns, Christian.
Late blight, caused by Phytophthora infestans is commonly thought to be the factor most limiting yield in organic potato production. However, because there is no fully effective fungicide available to control late blight, there are virtually no yield loss data available for organic farming conditions.  In large-scale experiments covering 2-6 ha from 2000-2002, late blight assessments were conducted throughout the season in small sections throughout the field. The same sections were harvested, resulting in between 400 and 700 data points per experiment and year. In a second set of experiments, from 2002-2004, the interactive effects of N-availability in the soil, climatic conditions and late blight were studied in the presence and absence of copper...

Effects of autumn kaolin treatments on the rosy apple aphid Dysaphis planaginea (Pass.) and possible modes of action.
Provedor de dados: 21
Autores: Bürgel, K.; Daniel, Claudia; Wyss, Eric.
Autumn applications of the repellent processed-kaolin particle film (Surround ® WP) might be an alternative to the insecticides commonly used in spring to control the rosy apple aphid, Dysaphis plantaginea (Pass.) (Hom., Aphididae). To assess the mode of action and the impact of kaolin on autumn forms of D. plantaginea, trials were conducted in field cages and in open-fields in autumn 2003. Choice and no-choice experiments in field cages showed that winged aphids landed in significantly lower numbers and gave birth to significantly fewer females on kaolin-treated branches compared with the untreated control. In a first open-field trial, single applications at 10 different dates and with two different concentrations of kaolin were conducted after harvest to...

Evaluation of module-sown companion plants as a method of controlling cabbage root fly
Provedor de dados: 21
Autores: Rosenfeld, Dr Anton; Collier, Dr Rosemary; Jayasinghe, Celenika.
A novel technique for controlling cabbage root fly was tested.   Companion plants of either birdsfoot trefoil (Lotus corniculatus), red clover (Trifolium pratense) or yellow trefoil (Medicago lupulina) were sown into modules together with calabrese (Brassica oleracea var Italica).  The presence of companion  plants subsequently reduced cabbage root fly egg-laying by up to 48% and reduced root damage considerably. Companion plant species did not affect egg-laying in this trial. Although, financially, this technique compares very favourably with an alternative strategy of applying fleece, further refinement is needed to improve the survival of companion plants on a commercial field scale as they were particularly vulnerable to damage by steerage hoes, which...

Autores: Montag, Jurith; Schreiber, Lukas; Schönherr, Jörg.
The post-infection activity of hydrated lime against conidia of Venturia inaequalis was evaluated using an in  vitro test system based on isolated apple leaf cuticles. Experiments were conducted at 20°C and treatments  were applied 24 or 48 h after inoculation. Experiments were assessed by counting living primary stromata 72  h after inoculation using fluorescence microscopy and fluorescein diacetate (FDA) as a vital stain. At the  conditions of the in vitro test system hydrated lime had a post-infection activity. Suspension of 5 g l-1 applied  24 h after inoculation (16 h after infection) killed all primary stromata and stopped their further development.  Treatments 48 h after inoculation reduced the number of vital primary stromata to 60% of control....

Proteome analysis of stored carrots grown in different cropping systems for evaluating changes in susceptibility to liquorice rot during storage
Provedor de dados: 21
Autores: LOUARN, Sébastien; JENSEN, Dan Funck; JENSEN, Birgit; NØRREGAARD JENSEN, Ole; NAWROCK, Arkadiusz.
During post harvest storage, a big amount of carrots (more than 50%) can be discared due to the development of liquorices rot caused by Mycocentrospora acerina. This fungus is soil borne and overwinters in the soil as clamydiospores. M. acerina is brought into the store in to soil adhering to the root. Control of liquorice rot is mainly related to physiological or structural resistance of carrot, and to other factors as storage conditions and cultural practices.  It is believed that carrots at the beginning of storage can resist disease development due to chemical defence mechanisms within some proteins and peptides are considered to be important. The hypothesis is that proteome changes during storage of carrots are related to the susceptibility to M....

Effects of sowing time on pink snow mould, leaf rust and winter damage in winter rye varieties in Finland
Provedor de dados: 21
Autores: Serenius, Marjo; Huusela-Veistola, Erja; Avikainen, Hanna; Pahkala, Katri; Laine, Antti.
Disease infection in relation to sowing time of winter rye (Secale cereale) was studied in southern Finland in order to compare overwintering capacity of modern rye varieties and to give recommendations for rye cultivation. This was done by using three sowing times and four rye varieties in field trials conducted at three locations in 1999–2001. The early sown rye (beginning of August) was severely affected by diseases caused by Puccinia recondita and Microdochium nivale, whereas postponing sowing for two weeks after the recommended sowing time resulted in considerably less infection. The infection levels of diseases differed among rye varieties. Finnish rye varieties Anna and Bor 7068 were more resistant to snow mould and more winter hardy than the Polish...

Diplodia seriata, cause of black fruit rot in organically grown apples in Holland, Belgium and Northern Germany
Provedor de dados: 21
Autores: Trapman, Marc; Maxin, Peter; Weber, Roland W. S.
A fruit rot resembling Gloeosporium infections but appearing on fruits prior to harvest was  noticed in organic apple orchards in Holland, Belgium and Northern Germany in 2007.  Infections were most commonly observed on ‘Elstar’, but other cultivars were also  affected. Fruit colonisation progressed in two steps, whereby a latent stage of sunken  black lesions in immature fruits gave rise to a rapidly spreading firm brown rot upon fruit  ripening. Isolation experiments from both stages consistently yielded a single species of  fungus identified as Diplodia seriata, formerly known under the teleomorph name  Botryosphaeria obtusa. Lesions of D. seriata were also seen on leaves as necrotic light  brown spots surrounded by a purple halo, and occasionally on...

Host age did not appear to affect the wasps  parasitization behaviour, although they spent longer time drilling on old eggs (4 and 5 days old)  compared with fresh ones (0 and 1 day old). This not necessarily means that they preferred fresh  eggs over old ones, since both type of hosts were parasitized in the...

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...

Prevent and control of  grapevine downy mildew
Provedor de dados: 21
Autores: Kassemeyer, Dr. Hanns-Heinz.
Abstract - To date in organic viticulture grapevine downy mildew is controlled mainly by treatments with copper. Under favourable conditions the disease spreads rapidly and causes severe losses of yield and quality. To develop a strategy for the biological con-trol of grapevine downy mildew, the infection cycle of the pathogen has been investigated in detail. On the basis of the biological data, a model for the specific control of grapevine has been developed. This model indicates the most suitable stages of the infection cycle for the precise control of the disease .

This study has improved our understanding of the phenology of the three species, which is of key importance to determine the timing and positioning of traps. Lure duration is one of the bottlenecks in designing commercially viable insect traps for monitoring or mass trapping. Our results emphasize that traps intended for more than one species and region either need long-lasting lures to cover all possibilities, or detailed knowledge about local conditions (e.g. prevalence of pest and surrounding host plant species etc.) to apply lures at the right time

A comparison between organic and integrated apple production: First results after 5 years of observation
Provedor de dados: 21
Autores: Kreuzwieser, Andreas; Kelderer, Markus.
Organic apple production is of increasing commercial importance throughout Europe, but  especially in South Tyrol where about 25% of the whole European organic apple crop is  produced.  In organic apple production, producers face the challenge of choosing varieties that are  both in demand and also resistant to the main pests and diseases. Every now and then,  the question arises, if yields, losses and profitability are different in integrated and organic  orchards and in how great are the differences between single apple varieties.  In 1999 the Laimburg Research Centre started a field trial to observe the effects of  different cultivation methods on 18 apple varieties in a randomised block design. In the first  four years of production, significant...

Leafhopper stippling damages in cultures of medical herbs and spices are increasing since the mid 1990s in various parts of Central Europe. We launched a project within the frame of the Federal Programme for Organic Farming (BÖL) in order to gain information on the taxonomic status of the pest, as well as its basic biology and current distribution. In addition to this we tested whether cicads could be controlled by organic insecticides such as azadirachtin, pyrethrum and quassia, and by entomopathogenic fungi as biological control agents.  We found stippling damages of varying extent in nearly all fields under study. The pest has been identified as a complex of species belonging to cicadellids of the subfamily Typhlocybinae. These cicads have feeding...

An artificial inoculation test method was established in the laboratory to  evaluate resistance of cherry genotypes to the leaf spot fungus, Blumeriella jaapii.  The reaction type to leaf spot of 52 sour cherry cultivars and 11 Prunus species was  evaluated. In result 10 sour cherry cultivars showed a resistant reaction type to leaf  spot. The tested Prunus species, P. canescens, P. incisa, P. kurilensis, P. maackii, P.  nipponica, P. sargentii, P. serrulata ssp. spontanea, P. subhirtella showed a resistant  reaction type to the leaf spot fungus. The species P. dawyckensis was susceptible.

Provedor de dados: 21
Autores: Wilbois, Klaus-Peter; Vogt-Kaute, Werner; Spieß, Hartmut; Müller, Karl-Josef.
Zur Erzeugung gesunden Saatgutes steht im Öko-Landbau neben präventiven Maßnahmen eine Reihe verschiedener Saatgutbehandlungsverfahren zur Verfügung (physikalische Methoden, Pflanzenextrakte, Naturstoffe und Mikroorganismenpräparate), die jedoch für die zahlreichen, wichtigen Wirt/Pathogen-Kombinationen nicht hinreichend untersucht waren. Inhalt und Ziel dieses Verbundvorhabens war es, Erfolg versprechende, aber hinsichtlich Handhabbarkeit und Wirksamkeit bislang nicht ausreichend untersuchte Varianten zu überprüfen sowie Schwellenwerte zu ermitteln, die eine Saatgutbehandlung indizieren.  Um eine schnelle Übertragbarkeit wirksamer Verfahren in die Praxis zu ermöglichen, wurden neben den physikalischen Verfahren überwiegend gelistete...

Representation of Potato Virus Y control strategies in current and past extension literature
Provedor de dados: 21
Autores: Döring, Thomas F.; Schrader, Joachim; Schüler, Christian.
The aphid-vectored Potato virus Y (PVY) is currently seen as an important limiting factor in the production of potatoes in many countries. Using a contentanalysis approach, we investigated the German extension literature for recommendations regarding the control of PVY. Media included articles from periodicals addressing farmers and agricultural textbooks published in the last five decades (1955–2004). In the current literature (1995–2004), the clearly dominating strategy was found to be insecticidal control, although this strategy has been subject to some criticism in the scientific literature. Over the last five decades we also found a strongly increasing representation of insecticidal strategies. Furthermore, over this period of time, information...

Influence of inoculum density of the antagonistic bacteria Pseudomonas fluorescens and Pseudomonas corrugata on sugar beet seedling colonisation and suppression of Pythium damping off
Provedor de dados: 21
Autores: Schmidt, C. S.,; Agostini, F.,; Leifert, C.,; Killham, K.,; Mullins, C. E.,.
The effect of initial inoculum density of the antagonistic bacterial strains Pseudomonas fluorescens 135 and Pseudomonas corrugata 2140 (10(3) to 10(8) CFU per seed pellet) on sugar beet seedling colonisation, in situ bioluminescence and antagonistic activity towards Pythium ultimum was investigated. Populations of the bacteria colonising sugar beet root systems approached an apparent carrying capacity of 10(5) to 10(6) CFU per plant after 12 d growth, irrespective of inoculum density. This meant an up to 320-fold population increase at low inoculum densities and a decrease at high densities. Population densities of both bacteria and their corresponding in situ bioluminescence (resulting from luciferase enzyme expression from the inserted luxAB genes)...

Spezifität und Nebenwirkungen auf Nutzorganismen von pyrethrinhaltigen Pflanzenschutzpräparaten
Provedor de dados: 21
Autores: Prokop, Andreas.
Spezifisch wirkt Pyrethrum nicht. Das liegt an seiner chemischen Zusammensetzung und dem zugrundeliegenden Wirkmechanismus. Das Pyrethrumkonzentrat, wie es in dem gereinigten Pale-Extrakt vorliegt, besteht aus sechs insektiziden, optisch aktiven Estern der Chrysanthemum- und Pyrethrinsäure. Diese aktiven Bestandteile des Pyrethrums werden auch Pyrethrine genannt. Die Hauptbestandteile jedes Pyrethrum Konzentrats sind Pyrethrin I und II. Die Pyrethrine beeinträchtigen die normale Funktion des zentralen Nervensystems der Insekten. In Freilandversuchen, in denen Photolyse und mikrobieller Abbau parallel erfolgen, war die ermittelte Halbwertzeit von Pyrethrin gering.

Alternatives to copper-based treatments for the control of grapevine downy mildew (Plasmopara viticola): 5-year synthesis of trials in France and Italy
Provedor de dados: 21
Autores: Parveaud, Claude-Eric; Gomez, Christelle; Chovelon, Marc; Lambion, Jérôme; Dagostin, Silvia; Pertot, Ilaria.
The objective of the UE-funded program REPCO (FP6) was to identify new alternatives to copper fungicides in organic farming. Two pathogens have been considered: grapevine downy mildew (Plasmopara viticola) and apple scab (Venturia inaequalis). Research on grapevine was carried out by GRAB (Avignon, France) and FEM-IASMA (San Michele all’Adige, Italy). Trials were carried out under natural conditions in order to test reduced doses of copper and copper-free alternatives. Five-year trials proved that copper is the best fungicide. However, the use of new low copper rate formulations and the association of copper-free alternatives with reduced doses of copper or with reduced number of copper applications (limited to the most susceptible grapevine growth stages)...

South Tyrol, the main Italian apple growing area, is characterised by an highly intensive soil cultivation. Previous investigations shows the existence of replant disorders although it has not been evaluated which are the main causes. A survey has been carried out in this area with two main aims I) to evaluate the role of soil borne pathogens in apple replant disease and II) to evaluate the effect of soil management toward soil borne pathogens causing replant diseases. The experimental sites were chosen in order to obtain three couples of contiguous conventional and organic apple orchards.  Soil sickness test with young apple plants gave a significant growth reduction in all soil samples if compared to a peat control. Among all root colonising fungi...

Konsekvenser ved sameksistens mellem økologisk raps og GM raps i Danmark
Provedor de dados: 21
Autores: Andersen, Naja Steen.
Inden for ganske få år forventes det, at GM sorter af raps vil blive dyrket i Dannmark. Raps er en af de danske afgrøder, der har det største potentiale for genspredning. Det er derfor nødvendigt at løse de sameksistensproblemer der vil opstå, når GM raps dyrkes i nærheden af økologisk raps og ikke-GM raps. I hvilken grad agerkål og spildraps og urenheder i certificeret rapsfrø bidrager til forekomsten af GM under forskellige forhold, undersøges i et igangværende projekt på Risø og KVL.

Abwehrmassnahmen gegen Krähenfrass im Mais 2012
Provedor de dados: 21
Autores: Dierauer, Hansueli; Böhler, Daniel; Kupferschmid, Cornelia.
Krähenschäden nehmen insbesondere auf Biomaisäckern zu. Durch die Beizung mit «Mesurol» sind konventionelle Maissaaten vor Krähenfrass geschützt. Das erhöht den Druck auf die Biosaaten. Für die Biobauern entstehen teilweise hohe Mehrkosten für Nachsaaten und verspätetes Ernten. Einzelne Landwirte haben sogar ganz mit dem Maisanbau aufhören müssen.  Im Jahr 2012 wurde die Wirkung der Ballone und der Maiskörnerbeizung gegen Krähenfrass weiter erforscht. Das Ziel der über dem Feld schwebenden Ballone ist, die Krähen abzuschrecken, indem sie Raubvögel simulieren. Mit der Beizung will man eine Geruch oder Geschmack abschreckende Wirkung erreichen. Das soll das Auspicken der Körner verhindern.  Die letztjährigen Versuche mit der Ballon Methode haben unter...

Clover:cereal bi-cropping for organic farms (OF0173)
Provedor de dados: 21
Autores: Clements, Dr R. O.
This is the final report of Defra project OF0173. The attached main report starts with a more detailed summary, from which this text is extracted.  IGER, IACR and others developed a system for growing cereals, especially for whole crop silage, that enables either greatly reduced or zero levels of N fertilizer and agrochemicals to be used.  The system is simple and straightforward and relies on direct drilling of the cereal into an established understorey of white clover.  The white clover understorey becomes permanent and perennial and successive cereal crops are drilled into it, harvested and re-drilled each year.  The clover provides N for the cereal crop and the gross changes in crop architecture that occur (a) encourage large populations of predatory...

EVALUATION OF THE EFFECTIVENESS OF NATURAL ALTERNATIVE COPPER PRODUCTS AND LOW RATE COPPER FORMULATIONS AGAINST GRAPE DOWNY MILDEW IN ORGANIC VITICULTURE
Provedor de dados: 21
Autores: La Torre, Anna; Spera, Guido; Talocci, Silvia; Cargnello, Giovanni.
The control of pathogenic fungi, especially downy mildew, represents the main problem in organic viticulture as only few fungicides, above all copper salts, can be used. As the copper causes problems of environmental impact, the Regulation EC n. 473/2002 fixed a ceiling on the use of copper compounds. Two years field trials were carried out in organic vineyeards to test the effectiveness, against Plasmopara viticola (Berk. et Curt.) Berl. et De Toni, of alternative copper products and low rate copper formulations, able to take place or to reduce copper quantities used. Amoung the alternative substances, in the first year of activity we examinated phito-stimulant and cuprics, while in the second year we examinated natural extracts, both vegetables and...

Kupferminimierungs- und Vermeidungsstrategien für den ökologischen Kartoffelbau (Teilprojekt A: Maßnahmen zur Reduktion des Primärbefalls)
Provedor de dados: 21
Autores: Nechwatal, Jan; Zellner, Michael.
Die Kraut- und Knollenfäule der Kartoffel (Phytophthora infestans) kann im ökologischen Kartoffelanbau bislang nur durch die Anwendung von Kupfer-Präparaten effektiv bekämpft werden. Die Anreicherung im Boden und negative Auswirkungen auf andere Organismen machen eine Reduktion des Kupfereinsatzes erforderlich. Ausgangspunkt einer Phytophthora-Epidemie sind oft infizierte Pflanzknollen, von denen aus sich primäre Infektionsstellen bilden. Vom infizierten Kraut abgespülte Sporen infizieren die neuen Knollen und somit das Pflanzgut für die nächste Saison. Im Rahmen des Projektes sollten Wege zur Reduktion des Primärbefalls im ökologischen Kartoffelbau gefunden werden. In zahlreichen Laborversuchen wurden über 20 Präparate auf ihre Eignung als...

La plupart des variétés résistantes aux maladies créées par les améliorateurs sont de type monogénique, c'est à dire que la résistance est due à un seul gène. Souvent ce type de résistance perd rapidement son efficacité au champ en raison de l’émergence de souches virulentes : on parle alors de contournement de la résistance. Les variétés de pommier portant le gène Vf de résistance à la tavelure n'échappent pas à cette règle. Le gène Vf a été introduit dans des variétés de pommier à partir du pommier ornemental Malus floribunda 821 (d’où le nom Vf, « V » pour Venturia et « f » pour floribunda).

Improved prevention and control of apple scab caused by Venturia inaequalis is aimed at without the use of copper containing products in the Repco-project. Substantial progress is made in selection of potential products against summer epidemics. A patent application is made for E73. New effective biocontrol agents are selected to reduce inoculum during winter. The product potassium bicarbonate has shown good efficacy and Repco contributes to the registration of this product in Europe. Earthworms tended to be stimulated to consume apple leaves treated with amino acids or beetpulp, especially when applied fresh under controlled environmental condi-tons.

Bekämpfungsstrategien für den Wurzelgallennematoden Meloidogyne hapla im Ökologischen Landbau
Provedor de dados: 21
Autores: Hallmann, Johannes; Rau, Florian; Puffert, Markus.
The root-knot nematode Meloidogyne hapla is a major pest in organic farming causing severe damage especially on vegetables. Common practices such as high cropping frequencies of legumes and low frequencies of cereals in association with unsatisfactory weed control are assumed to be major factors for nematode build-up. Due to the broad host spectrum of M. hapla strategies solely based on crop rotation are often not sufficient in controlling the nematode. A series of field experiments was conducted to develop more efficient control strategies. Based on the results a recommendation for reducing high nematode densities was developed which is build on black fallow throughout the main vegetation period buffered by additional measures such as previously growth of...

Autores: Spornberger, A.; Brunmayer, R.; Fischer, G.; Kaufmann, C.; Osterc, G.
Pear trees on their own roots are tested in comparison to grafted trees in growth and yield  characteristics and with special regard to the tolerance to diseases, above all fire blight  (Erwinia amylovora). In spring 2004 15 randomized trees of the cultivar 'Williams' from  three variants (self rooted in vitro, self rooted long cuttings, grafted on Quince A) were  planted in a pear orchard, which was heavily infected with fire blight (Erwinia amylovora)  the previous years. The trees were left untreated. Growth and yield characteristics, plant  diseases and tree losses were observed. After four years the in vitro self rooted trees were  significantly more vigorous in growth than those grafted on quince A. The self rooted long  cuttings were comparable in...

Biologische bestrijding van echte meeldauw in zomerbloemen
Provedor de dados: 21
Autores: Slootweg, Casper.
In de biologische teelt van zomerbloemen ondervinden de telers veel last van bovengrondse schimmelaantastingen (echte meeldauw, roest en bladvlekkenziekten). In dit project is een lijst met een tiental potentiële middelen tegen schimmels in buiten geteelde biologische zomerbloemen samengesteld. Voor veel van deze middelen bleek er geen zicht op een toelating, zodat het opnemen in een veldproef niet zinvol was.    Er zijn vier middelen in een veldproef opgenomen:  - Spuitzwavel (toegelaten)  - Twee middelen met toelating in andere teelten  - Eén experimenteel middel

Assessment of Farmers’ Plant Disease Knowledge in Organic Cacao Cultivation
Provedor de dados: 21
Autores: Heuschekel, Zoe; Home, Robert; Schneider, Monika; Pohlan, Jürgen.
The Alto Beni region on the eastern foothills of the Andes accounts for 90% of certified organic cacao production in Bolivia and other tropical products for the city of La Paz. In the region more than 2200 households strongly depend on the cultivation of cacao. Cacao is cultivated on small holder farms mostly in diversified agroforestry systems. These systems contribute to both the conservation of biodiversity and the food security of the farmers.  An outbreak of the frosty pod disease caused by Moniliophthora roreri in 2011 is now threatening these relatively sustainable production systems. Examples all over Latin America showed the abandonment and elimination of cocoa systems and the loss of biodiversity and local revenues after its attack. Frosty pod...

Compensating damage effects of seed-borne Fusarium culmorum and Microdochium nivale in winter wheat by increased seeding rates
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Justesen, A.F.
Fusarium culmorum and Microdochium nivale are considered important seed-borne diseases of wheat in Denmark. Their damage effects consist in reducing seed germination and plant emergence which leads to reduced plant density, panicle numbers/area and yield. The aim of this study is to find out whether and to what degree these damage effects can be compensated by increased seeding rates. A trial was therefore conducted in 2004 in which seed lots of three winter wheat varities (Ritmo, Bill and Boston) having various degrees of infection by F. culmorum and Microdochium nivale were sown at various seeding rates. Seed contamination of the two pathogens was determined by counting the number of discoloured roots in the seed batches (Doyer method). Plant emergence...

Atlas of agricultural entomology - a knowledge base of pest insects
Provedor de dados: 21
It is an atlas of insects and mites relevant in agriculture (as pest or as predators or other). It allows to search by picture of the order and by common name (in Italian). Each insect is described together with the damage it may cause, its biological cycle and the tools to keep it under control, being them ecological, agronomic or direct and in the last case including active substances allowed in conventional and in organic.  It may be used to identify an insect that a farmer finds in its crops and to have a first information on the causes of its presence and how to manage it.  This tool provide very good pictures of insects so it can be used with a really practical approach. This can be used to develop a strategy for control.

Abstract – Production of pathogen-free seeds is a major goal in organic farming. In the framework of the EU-funded project “STOVE” (“Seed Treatments for Organic Vegetable Production”) physical and biological methods of seed treatment (alone and in combination) were investigated in different vegetable / pathogen systems.   Overall, the physical treatments (hot water, hot air and electron treatment) resulted in a moderate to good control of the respective diseases. Also, from all biological treatment groups (microorganisms, plant extracts and inducers of resistance) candidates with promising control properties could be identified. The influence of the biological methods on emergence was often more prominent under greenhouse than under field conditions.  The...

Besides other legumes lupins belong to the local protein crops usuable as feeding stuff in ecologic farming. Therefore an important breeding aim is to provide lupins with high and stable protein content. A non-destructive analysis using near infrared transmittance spectroscopy was developed for determination of protein in single seeds of lupins. Calibration and validation equations were calculated on the basis of 300 single seeds of 3 blue lupins (‘Azuro’, ‘Bolivio’, ‘Boregine’) growing at 3 ecological locations. The estimation of protein content was possible in a range of 15-44% protein with a coefficient of determination (r²) of 0,907 and a standard error of prediction (SEP) of 1,86%. The equation was applied to evaluate the protein content of single...

Use of sown wildflower strips to enhance natural enemies of agricultural pests
Provedor de dados: 21
Autores: Pfiffner, Lukas; Wyss, Eric.
Intensive agriculture and excessive use of agrochemicals have resulted in an impoverished wildlife in agricultural landscapes, especially in arable landscapes but also in perennial high input crops. The elimination of semi-natural habitats, simplification of crop rotations as well as high input of fertilisers and pesticides is considered to be responsible for the severe decline of biological diversity that has been observed (e.g. Aebischer 1991). These practices can reduce habitat quality and remove the necessary habitat structure that is important to many natural enemies.  Moreover, agricultural landscapes are increasingly being simplified; with natural and semi natural areas fragmented and replaced altogether by large monocultural fields. As a...

Black vine weevil and other wingless weevils: are there any effective conrol methods applicable in outdoor strawberry in Nordic countries?
Provedor de dados: 21
Autores: Lindqvist, Isa; Tuovinen, Tuomo.
The black vine weevil (Otiorhynchus sulcatus) is a common pest in Central Europe but rather new on outdoor crops in Finland. Spreading of enthomopathogenic nematodes against weevils by drip irrigation was tested at MTT during 2003-2004. The results proved that at least in small-scale use the nematodes were easily spread through the irrigation system into the field. We were not able to prove the efficiency of the nematodes against larvae because of too low level of both species populations in the experimental cages in the field.

Blandsæd giver dig flere muligheder i dit markbrug
Provedor de dados: 21
Autores: Mejnertsen, Peter.
Blandsæd giver en række fordele frem for produktion af afgrøderne i renbestand. Den mest oplagte fordel ved blandsæd er, at det klarer sig bedre overfor ukrudt end afgrøden i renbestand. Hvis blandsæden består af korn og bælgsæd, har afgrøden endvidere et meget lavt gødningsbehov. Under FØJO er der arbejdet med dyrkning af blandsæd, hvor blandingen har bestået af korn og bælgsæd.

Autores: Parikka, P.; Lemmetty, A.
Expected changes in temperatures and rainfall will make it more likely than now for some diseases to spread and survive over the winter season in northern areas. Pathogens favored by changing climate include powdery mildews, Phytophthora species and bacterial pathogens. Colletotrichum species may also increase with changing host cultivation and viruses can benefit from increasing vector populations.

Fungal-mediated multitrophic interactions - do grass endophytes in diet protect voles from predators?
Provedor de dados: 21
Autores: Saari, Susanna; Sundell, Janne; Huitu, Otso; Helander, Marjo; Ketoja, Elise; Ylönen, Hannu; Saikkonen, Kari.
Plant-associated micro-organisms such as mycotoxin-producing endophytes commonly have direct negative effects on herbivores. These effects may be carried over to natural enemies of the herbivores, but this has been rarely explored. We examined how feeding on Neotyphodium endophyte infected (E+) and endophyte free (E−) meadow ryegrass (Scherodonus pratensis) affects body mass, population size and mobility of sibling voles (Microtus levis), and whether the diet mediates the vulnerability of voles to least weasel (Mustela nivalis nivalis) predation. Because least weasels are known to be olfactory hunters, we also examined whether they are able to distinguish olfactory cues of voles fed on E+ and E− diets. Neither body mass of voles nor population size...

'Attract &amp; Kill' - ein innovatives Konzept zur biologischen Bekämpfung von bodenlebenden Schädlingen
Provedor de dados: 21
Autores: Vidal, Stefan; Mävers, Frauke; Brandl, Michael; Przyklenk, Michael; Schumann, Mario; Patel, Anant.
Soil dwelling pest species are difficult to control because of their cryptic life style and their unpredictable distribution belowground. The efficacy of biological control agents is limited, mainly because of low rhizosphere competence. Here we propose to use a strategy where pest are attracted to killing agents instead of bringing killing agents to the pest. We developed capsules emitting carbon-dioxide which are combined with an specific isolate of an entomopathogenic fungus or Neem. The principle of an attract &amp; kill strategy takes advantage of the behaviour of soil dwelling larvae which use CO2 for locating their host plants. Components used for the production of the capsules are just contain biologically derived substances and therefore do not...

REPCO contribution to the development of products for apple scab control
Provedor de dados: 21
Autores: Jong, Ir. P.F. de; Heijne, Dr. Ir. B.
Natural compounds were sprayed according the RimPro scab warning system from start of bud break until the mid of June. Scab incidence was measured on the leaves and the fruit. Phytotoxicitiy and russet-ing was assessed. The natural compounds were sprayed together with sulphur and were compared with the standard biological fungicides copper hy-droxide and sulphur alone. Compound E73 + sulphur was the most effective on fruit. Armicarb and Resis-tim both sprayed with sulphur were comparable in efficacy with Funguran-OH. In our study laminarin (GL 32) did not shown any effect on the control of scab on apple.

The post infection use of Lime sulphur to control apple scab. Experiences in the Netherlands 1999-2002
Provedor de dados: 21
Autores: Trapman, Marc.
Until yet the fongicides in organic fruit growing (sulphur, lime sulphur, copper, claypowders) are used as protectants applied before the rain, or as stop-spray or during infection development. Post infection use of lime sulphur could reduce the number of spray rounds, allowing for the use of less pesticides, and reducing the adverse effect on beneficial insects and mites. In the 30's of the last century, post-infection effects of lime sulphur were found in lab and field trials. Effective control was achieved by applications 30 to even 72 hours after the start of rain. Field trials in the Netherlands in 1999, 2000 and 2001 confirmed that post-infection applications of lime sulphur are effective under field conditions till at least 20 hours after the start...

Agroforestry systems can mitigate the severity of cocoa swollen shoot virus disease
Provedor de dados: 21

Currently, the only effective treatment for cocoa (Theobroma cacao L.) infected with the cocoa swollen shoot virus disease (CSSVD) is to cut and replant infected trees. Hence, the development of preventive control measures and strategies to mitigate the severity of the disease are of utmost importance. While past research has mainly focused on resistance breeding, mild strain cross protection and vector control, diversification measures such as agroforestry have received relatively less attention, despite their potential to mitigate CSSVD severity.  Therefore, we studied the effects of shade on CSSVD symptom severity, capsid damage and cocoa yield along a gradient of increasing shade tree abundance in smallholder cocoa farms in Ghana. Furthermore, we...

Pflanzengesundheitliche Bewertung der besonderen Risiken für den ökologischen Landbau durch die Einschleppung und Verbreitung von gebietsfremden Schadorganismen
Provedor de dados: 21
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...

Ecological selectivity of pesticides and application methods
Provedor de dados: 21
Autores: Collier, Rosemary; Daniel, Claudia; Hommes, Martin; Jukes, Andrew.
According to David Pimentel, 20 years ago, less than 0.1% of the pesticides applied reached their target pests (Pimentel, 1995). This was partly due to ‘poor’ application methods and partly because of the minuscule amount of pesticide either picked up or consumed by the pest. At the time, Pimentel   was describing the application of pesticides mainly by sprays, including aerial spraying, and both pesticide chemistry and application technology have improved since then. However, a considerable proportion of pesticides are still applied as sprays, either to crop foliage or to the soil, and this continues to be a relatively untargeted method of application.

Plasmopara viticola, the causai agent of grapevine downy mildew is very well adapted to its host pianI. Therefore it is very difficult to develop methods for the biological control which meet the requests of ecological viticulture. One of the possibilities for a biological control of grapevine downy mildew is the usage of the natural resistance potential of the European cultivars of Vitis vinifera, more exactly the induced resistance. Another way is the use of specific inhibitors which either stop the infection process or have an effect on the interaction of the pathogen with the host pianI. Whereas generai information about the resistance reactions in plants is available and the first results were also won for vine, the knowledge about inhibitors is very...

Autores: Deloire, Alain; Ojeda, Hernan; Federspiel, Brigitte; Kraeva, Elena; Andary, Claude.
Grape derived secondary metabolites are the principal sources of wine aroma, flavor, color and taste. Most of available data about phenolics are concerned mature berries. Nevertheless, the contribution of flavonols in metabolism may be important, not only in red berries, but especially in green, when the berries are most susceptible to different kind of stresses. The changes in phenol composition in green berries, under water stress conditions (Ojeda et al., 2001; in press) and with different training systems (Kraeva et al., 2001; submitted) have been observed.

Autores: Tamm, Lucius; Amsler, Thomas; Schaerer, Hansjakob; Lévite, Dominique; Häseli, Andreas.
The currently used downy mildew control strategies in vitis vinifera in Switzerland are based on the use of acidified clay products combined with copper and sulphur.   Data from 1997-2003 show that acidified clay products are a valuable alternative to control downy mil-dew of grapevine in conditions of medium rain fall, good spray timing and with a good application tech-nique. The limits of these products show under heavy rain conditions and when there is high disease pressure.

Provedor de dados: 21
Autores: Hohmann, Pierre.
The overall aim of this study was to understand better the ecological behaviour of Trichoderma bio-inoculants in the root system of commercially grown Pinus radiata seedlings. Three Trichoderma isolates, representing three different species of the genus, were selected initially to investigate associations between rhizosphere competence and plant growth enhancement parameters. Improvements of various plant health and growth factors were confirmed for T. hamatum LU592 in a largescale experiment under commercial conditions. Application of LU592 increased seedling shoot height and the number of seedlings meeting market specifications by up to 9.5% and 5%, respectively. Strong rhizosphere colonisation and the ability to penetrate the roots were also...

Entwicklung und Bewertung von direkten Bekämpfungsstrategien gegen das Auftreten der Möhrenschwärze (Alternaria dauci) beim Anbau von Möhren für die industrielle Verarbeitung
Provedor de dados: 21
Das Forschungsvorhaben hat zum Ziel, die Sicherheit und damit die Wirtschaftlichkeit des Industriemöhrenanbaus zu verbessern. Dies soll einerseits durch die entsprechende Sortenwahl und andererseits durch direkte, den ökologischen Anbaubedingungen entsprechende Pflanzenschutzverfahren (Behandlung des Saatgutes, Ausbringen von Pflanzenstärkungsmitteln und Pflanzenschutzmitteln) geschehen. Die Vermeidung des Anbaus von für Alternaria anfälligen Sorten ist in ökologischen Anbauverfahren als Basis jeder Regulierungsstrategie anzusehen, da diese Vorgehensweise am ehesten den Vorstellungen der ökologischen Landwirtschaft entspricht. Da es im Bereich der Sorten für den Industriemöhrenanbau jedoch bisher nur mehr oder weniger starke Anfälligkeiten für Alternaria...

Wirkungsweise von Myco-Sin bei der Feuerbrandbekämpfung
Provedor de dados: 21
Autores: Kunz, Stefan; Ernst, Annegret.
The biocontrol agent Myco-Sin is used as plant health enhancer for fire blight control in ecological fruit growing. Using two in-vivo-systems indications for the mechanism of action of Myco-Sin were found. Myco-Sin clearly reduced the development of fire blight symptoms on detached pear blossoms, because the growth of Erwinia amylovora on stigmas and hypanthia was inhibited. With a pathogenicity test on immature pear fruits the resistance inducing effect of Myco-Sin was confirmed.

High damage potential of seed-borne spot blotch in organically grown spring barley in Denmark
Provedor de dados: 21
Autores: Pinnschmidt, Hans O.; Nielsen, Bent J.; Hansen, Henrik J.
Spot blotch of barley (Bipolaris sorokiniana, perfect state: Cochliobolus sativus) occurs wherever barley is grown but is normally not considered a major problem in Danish barley production. It is therefore not included in routine disease surveys or official variety testing in Denmark. However, recommended seed contamination thresholds are 30% for spring barley and 15% for winter barley. Several spring barley varieties were grown under organic (no seed dressing, mechanical weeding) and conventional (seed dressing with fungicides, herbicide application) production conditions at three sites in Denmark in 2003. The harvested seeds were analysed for contamination levels of seed-borne B. sorokiniana using a blotter method. The percentage of seeds contaminated...

Results of studies on plant health in organic cultivation on the background of other farming systems
Provedor de dados: 21
Autores: Lukanowski, Aleksander; Baturo, Anna; Sadowski, Czeslaw; Kus, Jan.
Investigations concerned effect of organic and other farming systems on cereal health status. Research material were roots, stem bases, leaves, ears and harvested grain of winter wheat and spring barley. Results showed lower health of spring barley in organic system, while this farming system did not affect winter wheat negatively. Fusarium spp. were prevalent among pathogens of winter wheat in all systems and in the case of spring barley - in integrated and conventional system. The exception was organically grown barley where Bipolaris sorokiniana dominated. Alternative seed treatment methods used in these studies did not limit growth of B. sorokiniana considerably, but some tendencies to lower incidence of this species on barley seedlings were noted....

Transdisciplinary systems research to develop a holistic approach to reduce the spread and impact of cocoa swollen shoot virus disease in Ghana (TransdisCSSVD)
Provedor de dados: 21
Autores: Andres, Christian; Gattinger, Andreas; Kwame Dzahini-Obiatey, Henry; Kwame Offei, Samuel; Six, Johan.
West Africa is the world’s most important cocoa (Theobroma cacao L.) growing region. The Cocoa Swollen Shoot Virus Disease (CSSVD) is one of the major productivity limitations, particularly in Ghana. Some 800’000 farm families’ livelihoods depend on revenues from the crop in Ghana alone. The only measure to treat CSSVD is to cut out infected trees. The national eradication program, implemented by the Ghanaian government since 1946, has cut out more than 250 million trees until today. Despite these efforts, CSSVD is still prevalent in the field. Research has tried to contribute to CSSVD control through breeding for resistant varieties, as well as investigating the effects of barriers with immune crops and protection through a “vaccination” with the mild...

Control of Phytophthora infestans in organic potato production
Provedor de dados: 21
Autores: Forrer, Hans-Rudolf; Musa, Tomke; Krebs, Heinz; Dorn, Brigitte.
Phytophthora infestans, the cause of late blight, is the most devastating pathogen in potatoes world-wide. To replace copper fungicides in organic potato production, we examined preparations based on plant extracts, micro-organisms, and other natural compounds for their effect on late blight in field trials as well as in vitro and in vivo. Most of this work we realised as participants of the EU project Blight-MOP. The majority of the preparations effectively inhibited P. infestans in vitro or in vivo on tomato plants. However, under field conditions and with applications once a week, commercial and experimental copper-free preparations failed to sufficiently control late blight.  In contrast, copper fungicides applied according to the decision support...

Autores: Hakala, Kaija; Hannukkala, Asko; Huusela-Veistola, Erja; Jalli, Marja; Peltonen-Sainio, Pirjo.
A longer growing season and higher accumulated effective temperature sum (ETS) will improve crop production potential in Finland. The production potential of new or at present underutilised crops (e.g. maize (Zea mays L.), oilseed rape (Brassica napus L.), lucerne (Medicago sativa L.)) will improve and it will be possible to grow more productive varieties of the currently grown crops (spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), oats (Avena sativa L.)). Also cultivation of autumn sown crops could increase if winters become milder and shorter, promoting overwintering success. Climatic conditions may on the other hand become restrictive in many ways. For example, early season droughts could intensify because of higher temperatures and...

Neue Ansätze zur Optimierung der Kraut- und Knollenfäulebekämpfung im ökologischen Kartoffelanbau
Provedor de dados: 21
Autores: Benker, Marianne; Zellner, Michael; Wagner, Steffen.
Die Bekämpfung der Kraut- und Knollenfäule stellt im Ökologischen Kartoffelanbau nach wie vor ein ungelöstes Problem dar. Bisher kann der Befall nur durch Einsatz von kupferhaltigen Pflanzenschutzmitteln reguliert werden. Ziel des Forschungsprojektes ist es, auf Basis der witterungsbedingten Epidemiebewertung den Einsatz kupferhaltiger Fungizide im Ökologischen Kartoffelanbau auf das absolut notwendige Maß zu begrenzen. Durch eine Beizung des Pflanzgutes mit Kupferpräparaten soll das Auftreten von Primärbefall reduziert werden, um den Epidemiebeginn und somit auch den Spritzstart nach hinten verlagern zu können. Zur Kontrolle des Sekundärbefalls sollen Fungizidstrategien erarbeitet werden, bei denen die Kupferaufwandmengen und die Spritzabstände variabel...

Danish wheat varieties are tested on a set of different Tilletia populations for their level of resistance. Resistance to bunt is studied by inoculating seeds artificially with different populations of bunt before sowing. 5 g of spores per kg of seeds is used, and the ”isolates” used are selected among the 50-60 different populations of bunt collected from different parts of the country. 2-3 different populations are used for inoculation the first year, and varieties showing good resistance are tested further in the following years on 3-6 new populations. The susceptible variety Herzog (up to 86% attack) and the highly resistant variety Stava (normally 0-0.2% attack) are included every year as reference. In July the number of ears with attacks of bunt is...

Crop protection in organic agriculture - a simple matter?
Provedor de dados: 21
Autores: Litterick, Audrey M; Watson, Christine A; Atkinson, David.
This report was presented at the UK Organic Research 2002 Conference. Crop protection strategies in organic agriculture and horticulture aim to prevent pest, disease and weed problems through optimisation of the cropping system as a whole. Choice of crops and varieties within the rotation and use of appropriate husbandry practices are critical to the success of the system and direct curative action against pests and diseases is rarely necessary. Research is urgently needed to determine strategies for control of key pests and diseases in organic systems if UK organic agriculture is to expand to meet increasing consumer demand. This paper describes current prevention and control strategies for pests, diseases and weeds in UK organic agriculture and...

OPTIMIZATION OF PLANT PROTECTION PRODUCTS  TREATMENTS AGAINST PLASMOPARA VITICOLA
Provedor de dados: 21
Plant protection in conventional farming, and even more so in organic farming, requires  careful and prudent action agro-environmental monitoring and epidemic risk assessment.  Often, however, the plant protection products are distributed in a non-targeted way, even  when reduced incidence of pests do not require any treatment.  In order to optimize the treatments against downy mildew, multi-annual field trials, both in  conventional and organic vineyards, have been carried out.  In all farms were considered 3 thesis: 1 untreated control thesis (Test), in order to follow the  coarse of infection, 1 standard farm reference thesis (St), where the treatments were carried  out according to the usual farm procedures and 1 experimental thesis (X).

Towards Grower-friendly Apple Crop Thinning by Tree Shading
Provedor de dados: 21
Autores: Widmer, A.; Kockerols, K.; Schwan, S.; Stadler, W.; Bertschinger, L.
Light management with shading nets, which reduce sunlight by 74%, might be an  alternative to chemicals commonly used for thinning on apple trees. To study the effect of  shading on crop load and fruit quality, trials were conducted in field experiments with the  cultivars Golden Delicious and Elstar in 2006. Trees were either covered 25 days after full  bloom (DAFB) with a net during three days, or until the peak of fruit fall, observed after  seven days shading. Ideal time length for optimal crop yield was seven days shading for  Elstar and three days shading for Golden Delicious. Alternate bearing could be decreased  as flower initiation counts the following year showed. In both experiments, inner quality of  fruit such as sugar and firmness showed good...

POTENTIAL OF EXTRACTS OF SOME ETHIOPIAN MEDICINAL PLANTS FOR LATE BLIGHT CONTROL IN ORGANIC POTATOES
Provedor de dados: 21
Autores: Tadesse, Mekuria; Neuhoff, Daniel.
The potential of ethanolic extracts of some common medicinal plants of Ethiopia for control of late blight (Phytophthora infestans) in tomatoes and potatoes has been investigated in vitro and in vivo. The application of several ethanolic plant extracts resulted in a significant inhibition of mycelium growth (0.25% m/v) and an impairment of late blight disease severity in vivo (1% m/v). Extracts from Hagenia abyssinica, Lepidium sativum and Lippia adoensis showed the strongest suppression of mycelium growth. The application of extracts derived from the H. abyssinica gave the highest in vivo bioactivity against P. infestans on tomatoes, but no effect was noted in potatoes under field conditions. The general potential of these extracts for late blight control...

Biological control of apple scab and fire blight by the application of the non-pathogenic bacterium Pseudomonas fluorescens Bk3 to the leaf surface
Provedor de dados: 21
Autores: Schmoock, S.; Kürkcüoglu, S.; Gau, A. E.
The biological control of plant diseases by application of antagonistic microorganisms to  the plant phyllosphere is an alternative strategy to prevent the frequent treatment of plants  by pesticides. Microbiological antagonists can firstly interact directly against the pathogen  by releasing antimicrobial compounds and/or secondly induce the plant resistance of the  host plant by expression of pathogenesis-related proteins (PR proteins). The focus of our  study is on the interaction of the non-pathogenic bacterium Pseudomonas fluorescens Bk3  to the plant phyllosphere of Malus domestica cv. Holsteiner Cox. After application of P.  fluorescens Bk3 to the phyllosphere of M. domestica cv. Holsteiner Cox we observed  dramatic changes in the protein...

Monitoring Agriotes lineatus and A. obscurus in organic production using pheromone traps
Provedor de dados: 21
Autores: Sufyan, Muhammad; Neuhoff, Dr. Daniel; Köpke, Prof. Ulrich.
Wireworms, particularly Agriotes lineatus and A. obscurus are becoming a problem in organic crop production causing economically severe damage on potatoes and other arable crops. Since pesticide application for direct control is not allowed in organic farming, reliable methods for quantifying wireworm infestation levels and forecasting damage are urgently needed for any control strategy. In the present work, the assessment of the range of attractiveness of pheromone traps to male A. lineatus and A. obscurus beetles was investigated in 2006 and 2007. The results indicated that the trap recovery rate of released beetles was more dependent on release distance than on time. Recovery rates greater than 40% were only noted for short release distances (up to 10...

This is the final report of Defra project OF0166. There is a longer summary at the start of the attached main report.  For many farmers and growers, a move to organic production presents major challenges. Among these, the issues regarding the use of organic seeds could yet be a stumbling block, as growers and the seed trade have reservations about using and producing them for four major reasons:  1) The availability of a wide range of organic varieties appropriate to all year round crop scheduling, and differing production techniques and markets   2) The impact of derogation on  managing the supply and demand for organic seed   3) The technical issues of organic seed production  4) Maintaining high standards of  seed quality, hygiene and vigour.

Companion cropping for organic field vegetables (OF0181)
Provedor de dados: 21
Autores: Wolfe, M. S.; Cormack, W. F.
Typical organic crop rotations are extensive with at least one year in four as a fertility building crop. However, the economic viability of organic systems may be compromised by having 75% or less of the farm productive at one time, limited further by the absence of the Arable Area Payments Scheme, particularly Set-aside, for vegetable crops. In addition, the system gives rise to a high fertility/low fertility sequence which is inefficient in terms of nutrient management (particularly nitrogen). To try to address this, the use of permanent beds of companion crop grown alongside the vegetable crops has been developed under various conditions around the world and is perceived as a possible alternative in organic husbandry. Companion crops also have the...

Blattoberflächen-modifizierende Salzapplikationen sollten als Bekämpfungsmittel gegen Echten Mehltau an Tomaten und Gurken getestet werden hinsichtlich folgender Eigenschaften:  - Wirkung verschiedener Salze  - Blattverträglichkeit  - Untersuchung der unterschiedlichen Wirkungsmechanismen mittels REM  - Übertragbarkeit in praxisnahe Versuche.     Die verschiedenen Salzlösungen und Kombinationen aus diesen Salzen unterschieden sich deutlich in ihrer Wirkung auf Gurkenmehltau. Die beste Wirkung ergab sich mit allenfalls geringer Schädigung des Blattes mit 0,1% MnCl2, 1 % Patentkali (K2SO4/MgSO4) und 1% Knöterichextrakt. MnCl2 liegt auf Grund seines niedrigen Deliqueszenzpunktes ständig gelöst auf der Blattoberfläche vor, wogegen sich Knöterichextrakt und...

Potato Virus Y reduction by straw mulch in organic potatoes
Provedor de dados: 21
Autores: Saucke, H; Döring, Thomas F.
Potato virus Y (PVY) is transmitted non-persistently by winged morphs of many aphid species and is a major problem in seed potato production. In order to evaluate the potential of straw mulch applications (4-5 t ha-1) and presprouting on PVY reduction, small scale organically managed field experiments were carried out in Northern Hessen, Germany, over 3 yr. In all years mulching significantly reduced aphid infestation on leaves as well as PVY incidence in tubers. For the effect of presprouting  the temporal coincidence of two factors was crucial � crop emergence and aphid flight activity.  Presprouting decreased PVY incidence when in the phase of early crop emergence aphid spring flight activity was low, but increased it, although not significantly, when...

Regulation of Plant Protection in Organic Farming
Provedor de dados: 21
Autores: Speiser, Bernhard; Tamm, Lucius.
Organic farming is a system approach aiming at a sustainable ecosystem, safe food, good nutrition, animal welfare and social justice. Quantitatively, organic farming is still of minor importance, but it is one of the most rapidly growing agricultural sectors worldwide. The new EU 'organic regulation' consists of a framework regulation, complemented by implementation rules and guidelines. Other important regulations/standards are the National Organic Program of the USA, the guidelines of the Codex Alimentrius and the basic standards of the International Federation of Organic Agriculture Movements (IFOAM). Under all these standards, plant protection is strictly regulated. Organic plant protection follows a clear hierarchy: primarily, plant health is...

Biological control of kiwifruit and tomato bacterial pathogens
Provedor de dados: 21
Autores: Balestra, Dr Giorgio M.; Rossetti, Dr Antonio; Quattrucci, Dr Alessio.
Biocontrol of bacterial pathogens is effected by using cupric salts associate to appropriate agronomical practices such as seed certification, irrigation and fertilization.  In in vitro and in in vivo tests, aqueous extracts from Allium sativum and Ficus carica fruits reduce the survival and the damages (disease incidence and disease severity) caused by bacterial pathogens of kiwifruit (Pseudomonas syringae pv. syringae, Pseudomonas viridiflava) and of tomato (Pseudomonas syringae pv. tomato) plants. In vitro tests, both vegetal extracts show antimicrobial activity against all bacterial strains utilised at different concentrations (106 – 108 cfu ml-1). In vivo tests Allium sativum and Ficus carica extracts confirm their antimicrobial activity on P. s. pv....

Index beregner hvor godt økologisk vårbyg konkurrerer med ukrudt
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Hansen, Preben Klarskov.
Kornafgrøder og –sorter har forskellig evne til at undertrykke ukrudt. Dette skyldes blandt andet sortens evne til at skygge for lyset og optage vand og næringsstoffer. For sorter med en samlet god konkurrenceevne gælder at:    de er langstråede   de har kraftig bladmasse gennem vækstsæsonen   de har en hurtig fremspiring og vækst    Denne viden er udnyttet til at beregne et konkurrenceindeks af sorten overfor ukrudt. De fleste forsøg vedrørende disse forskelle er gennemført under konventionelle forhold, hvor niveauet af næringsstoffer er højt, og ukrudt og andre skadevoldere bekæmpes kemisk.    Under økologiske forhold vil der oftest være en lavere og mere varierende forsyning med næringsstoffer. For at afklare om dette har en betydning for...

There is virtually no information available on the relationship between the reaction of tomatoes to Phytophthora infestans on leaves and fruits. Late blight and brown rot of tomatoes were assessed in outdoor conditions in 2005 on 15 tomato varieties and in 2006 for 41 varieties. Leaf disease expressed as area under the disease progress curve (AUDPC) and the proportion of healthy fruit of the total fruit were used as meas-ures. In 2005, the two varieties that were most susceptible to leaf blight produced the least healthy fruit while the most resistant variety produced the highest proportion of healthy fruit. However, for the varieties with more intermediate reactions to leaf blight there was great variation in the proportion of healthy fruit with an...

Abstract –At present grapevine downy mildew is controlled by fungicides mostly not suitable for or-ganic viticulture. The aim of REPCO (Replacement of Copper Fungicides in Organic Production if Grapevine and Apple in Europe) is to find new copper replacing products. Also the activation of the innate defence response by resistance inducers is a potential ap-proach for the biological control of grapevine downy mildew in organic viticulture. The efficacy of potential biofungicides and resistance inducers against grape-vine downy mildew was tested on leaf discs and on cell suspension culture, respectively. In a first step the direct effect on the pathogen is assessed in a leaf disc test. The activation of defence response is de-termined in a cell suspension...

K-phosphite is very efficient against several plant diseases. Nevertheless at the moment there is no official registration in Europe as a plant protection material. In conventional winegrowing K-phosphite is used in different countries to regulate the main disease ‘Plasmopora viticola’ under the disguise of a foliar fertilizer or a plant strengthener. In organic apple production only a few fungicides to regulate scab are available. In addition, copper products are limited by European and national legislations. The discussion about K-phosphite for organic farming points always at the problem of synthetic residues on the edible parts of the vegetables. The aim of this field-trial carried out during the season of 2005 was to assess the residues on apples...

Micellar electrokinetic capillary chromatography—Synchronous monitoring of substrate and products in the myrosinase catalysed hydrolysis of glucosinolates
Provedor de dados: 21
Autores: Bellostas, Natalia; Sorensen, Jens Christian; Sorensen, Hilmer.
A micellar electrokinetic capillary chromatography (MECC) method has been developed for monitoring the myrosinase catalysed hydrolysis of 2-hydroxy substituted glucosinolates and the simultaneous formation of the corresponding degradation products (oxazolidine-2-thiones (OZTs) and nitriles). Glucosibarin ((2R)-2-hydroxy-2-phenylethylglucosinolate) was chosen as the model glucosinolate owing to the difficulties in determining hydrolysis rates of this type of substrates in traditional UV-assays. The method was afterwards validated with glucobarbarin ((2S)-2-hydroxy-2-phenylethylglucosinolate) and progoitrin ((2R)-2-hydroxybut-3-enylglucosinolate). Aromatic glucosinolates without a 2-hydroxy group in their side chains, such as glucotropaeolin...

What do we (need to) know about low-susceptibility of codling moth against Cydia pomonella granulovirus (CpGV)!
Provedor de dados: 21
Autores: Jehle, Johannes A.; Wahl-Ermel, Britta.
In 2005, the first codling moth (CM) populations with a reduced susceptibility to Cydia pomonella granulovi-rus (CpGV) products have been observed. This phenomenon might be an indicator of an emerging resis-tance of CM to CpGV. This paper summarizes some aspects of CM CpGV interaction and discusses poten-tial mechanisms in the host virus interaction, which could contribute to the observed low susceptibility. In order to develop and implement successful resistance management strategies, much more knowledge about the plasticity of CM CpGV interaction and the diversity of CM populations is essential.

Reduced crop damage by self-regulation of aphids in an ecologically enriched, insecticide-free apple orchard
Provedor de dados: 21
Autores: Cahenzli, Fabian; Pfiffner, Lukas; Daniel, Claudia.
Enhancing natural enemies for pest management in agriculture is an expanding approach offering new opportunities for pest control and the potential to reduce insecticide use. Numerous studies in a variety of cropping systems clearly have shown that adequate measures can benefit natural enemies. However, although carry-over effects from an increase in natural enemies and a subsequent decrease in pest populations leading to a reduction in crop damage are always assumed, they are rarely proven. We established an insecticide-free apple orchard optimized for the self-regulation of pests by supporting natural enemies with shelter, nectar, alternative prey/hosts, and pollen. For six growing seasons, we focused on the control of the major apple pest Dysaphis...

Zusammenfassung  Im Rahmen eines vom Bundesprogramm ökologischer Landbau (BÖL) geförderten Projektes wurden Strategien für den ökologischen Kartoffelanbau entwickelt, welche eine Optimierung des Kupfereinsatzes ermöglichen. Neben dem witterungsbasierten Modell „Ökosimphyt“, welches den optimalen Spritzzeitpunkt und die Aufwandmengen berechnet, um den sekundären Blattbefall zu kontrollieren, wurde die Kupferbeizung der Pflanzknollen zur Kontrolle des primären Stängelbefalls untersucht. Es konnte gezeigt werden, dass von latent befallenem Pflanzgut ein großes Gefährdungspotential für den Bestand ausgeht. Durch die getestete Kupferbeizung des Pflanzgutes mittels ULV-Technik kann bei einem geringen Kupferaufwand von 120g/ha ein deutlicher Rückgang des primären...

Im ökologischen Weinbau sind Alternativen für Kupfer zur Bekämpfung der Rebenperonospora dringend erforderlich. Verfahren zur biologischen Bekämpfung sind erwartungsgemäß dann am erfolgreichsten, wenn sie an einer Schwachstelle des Erregers ansetzen. Zur Charakterisierung von Schwachstellen im Infektionszyklus der Rebenperonospora (Plasmopara viticola) wurden mikroskopische und zellbiologische Untersuchungen durchgeführt. Dabei konnten die einzelnen Phasen des Zyklus dargestellt und ihr zeitlicher Ablauf ermittelt werden. Schwachstellen wurden vor allem während des Infektionsprozess vor dem Eindringen des Erregers in die Pflanze gefunden. In dieser Phase liegen Zoosporen vor, die sehr empfindlich auf natürliche Hemmstoffe reagieren. Die cytologischen...

Autores: Daniel, Claudia; Matray, Silvia; Gallati, Philip; Tuchschmid, Andi.
Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa eingeschleppt und verursacht seitdem z.T. massive Ertragsausfälle. Aufgrund der Witterungsbedingungen wurden im Jahr 2014 erstmals starke Schäden am Wein festgestellt. Per Ausnahmebewilligung hat das BLW für das Jahr 2014 den Einsatz von Kaolin (Produkt Surround) bewilligt, jedoch mit dem Hinweis: „Die Auswirkungen einer Behandlung auf die Gärung der Maische aus behandelten Trauben wurde nicht untersucht.“ Viele Produzenten setzten im Jahr 2014 auch Kalkprodukte ein. Ein solcher Einsatz kann jedoch den pH-Wert anheben und somit einen Einfluss auf die Vinifikation und die Weinqualität haben. Das Ziel dieses Versuches ist es, den Einfluss von verschiedenen stäubenden Mitteln...

Autores: Kern, Simone.
Sooty blotch disease caused by a complex of different funghi. The incidence and severity of these disease are dependent on moisture and temperatur conditions during the summer months. A great problem is to fix the exactly ti me of infection. If this would be possible the threaten apple orchards could be better controlled by plant protection.  To date the exactly ti me of a possible infection, the apple fruits were wrapped in plastic films during the growing season. After full flower the fruits were bagged on various dates and kept covered until harvest.  The first symptoms of sooty blotch disease appeared in the apple orchard at 17 July 2000. If the time of infection is dated 2-3 weeks bevor the first symptoms appeared, so the infection could be placed to...

Sortenmischungen bei Getreide: Eine Chance für die ökologische Qualitätsproduktion
Provedor de dados: 21
Autores: Finckh, Maria R.
Um eine hohe Backqualität vor allem auch für Weißmehlprodukte zu erreichen, muss der Weizen optimal mit Nährstoffen versorgt werden. Dies bedeutet im ökologischen Landbau, dass das N-Angebot erhöht werden muss. Während dies einerseits Erträge und/oder Qualität steigern kann, erhöht es andererseits auch die Anfälligkeit des Bestandes vor allem gegenüber obligaten Pathogenen, wie Rost und Mehltau. Außerdem nimmt der Fusariumbefall bei erhöhtem N-Angebot deutlich zu. Fusariumbefall beeinflusst die Qualität durch die Produktion von Mykotoxinen sowie durch eine unmittelbare Verminderung der Backqualität.

Autores: Vänninen, Irene; Worner, Susan; Huusela-Veistola, Erja; Tuovinen, Tuomo; Nissinen, Anne; Saikkonen, Kari.
It is assumed that climate change will promote pest invasions and their establishment in new regions. We have updated the list of current alien invertebrate pest species in Finland and produced a list of potential new alien pests using a self-organizing map (SOM) that ranks species in terms of their risk of entry into Finland. The 76 pest species recorded included 66 insects, 5 nematodes, 2 mites and 3 slugs. Nearly half of the alien species appeared to have invaded Finland during the last 48 years. The SOM analysis is considered a viable tool for identification of potentially high-risk invasive pests from among the multitude of potential alien invaders, and represents a useful complement to local expert knowledge-based risk assessment of potentially...

Optimisation of different physical methods for control of seed-borne pathogens in organic vegetable production
Provedor de dados: 21
Autores: Jahn, Marga; Nega, Eva; Kromphardt, Carola; Forsberg, Gustav; Werner, Sigrid.
In the last decade, a lot of work has been done to develop new measures or to optimise existing seed treatment methods for use in organic farming. In the field of vegetable seed protection, national research projects as well as the EU-funded project “STOVE” (“Seed Treatments for Organic Vegetable Produc-tion”) are currently carried out.  Among the physical methods, hot water, humid hot air and electron treatment are being investigated. All three physical treatment methods show clear reduc-ing effects on pathogens of infested vegetable seeds. Degree of effectiveness connected with a good com-patibility depends on the treatment method and on the host-pathogen-system, but also on the cultivar and even on the seed lot.

Bekämpfungsstrategien für pflanzenparasitäre Nematoden im ökologischen Landbau
Provedor de dados: 21
Autores: Hallmann, Johannes; Klinger, Sonja; Rau, Florian.
Plant parasitic nematodes are an increasing threat to organic farming in Germany. Especially taxa with broad host spectra and high multiplication rates such as Meloidogyne hapla and Pratylenchus spp. can cause severe damage up to total loss of the crop. The control of these nematodes is extremely difficult. Resistant cultivars are not available and only few non-host crops are known. Weed control is another important issue as most weeds are excellent hosts. In 2003 and 2004 two on-farm trials aimed at controlling M. hapla and Pratylenchus spp. were conducted in Niedersachsen, Germany. Results from these trials can be summarized as follows. For M. hapla, best control was achieved with black fallow and maize in combination with weed control. Fodder radish...

A four year study to monitor fourteen organic farms for weed incidence throughout England and Wales began in  summer 1993.  Two farms were selected from each of the ‘former ADAS’ regions these being; East, Midlands and West, North, South East (Reading), South East (Wye), South West (Bristol) and South West (Starcross).  Each pair of farms had been using organic production for different periods of time.  On each farm, five fields were selected at random and assessed for weed incidence and severity in December, March, May and July.  If a field was in wheat, a sample of fifty tillers was collected at random at GS 75 (July) from a diagonal traverse.  Samples were assessed for severity of all foliar, stem-base and ear diseases.

Field efficacy of new compounds to replace copper for scab control in organic apple production
Provedor de dados: 21
Autores: Heijne, B.; de Jong, P.F.; Lindhard Pedersen, H.; Paaske, K.; Bengtsson, M.; Hockenhull, J.
Efficacy of compounds was investigated in field experiments in Denmark and the Netherlands according to EPPO guidelines. Some Yucca extracts and potassium bicarbonate had an efficacy similar to sulphur on leaves. Addition of sulphur to Yucca 1 and to potassium bicarbonate increased the level of efficacy to that of copper. This confirms results from earlier years. Although a dose increase resulted in better efficacy, this was more prominent for Yucca1 than for potassium bicarbonate.

Induced resistance: a strategy for the control of grape downy mildew?
Provedor de dados: 21
Autores: Buchholz, G.; Kassemeyer, H.-H.; Seibicke, T.
A desirable goal not only in organic viticulture is the application of ecologically harmless active agents for the control of fungal diseases. A potentially successful approach to inhibit growth and propagation of the pathogens is the induction of the plant's defence mechanisms through application of suitable compounds. Screening to identify potential elicitors might be facilitated by using model systems. Therefore a glucanase-promoter/reporter system in transgenic grape cell culture was established, to analyze potential inducers of PR-protein transcripts.  In assays with floating leaf-discs structural analogs of the highly effective 3-aminobutyric acid (BABA) and other amino acids were tested with regard to the inhibition of Plasmopara sporulation.

Survey on the control methods of Bactrocera oleae (Gmelin) in organic olive groves producing oil and table olives in Sicily
Provedor de dados: 21
Autores: Caleca, Virgilio; Palumbo Piccionello, Manuela; Battaglia, Isabella; Dimino, Silvana.
In Sicily there are several organic farms producing olive oil and the number of farms has grown in the last years.  The control methods of Bactrocera oleae (Gmelin) used by Sicilian organic farms were surveyed in 2004 and 2005. After a bibliographic search on  internet and by personal contacts, a sample of 30 organic farms in Sicily was chosen; 23 farms produce bottled extra-virgin oil and 7 produce table olives. Then farms were contacted by phone, some of them visited and olive growers were interviewed. For each farm were put together data about: interventions vs. the olive fruit fly, altitude, surface of the olive grove, olive cultivar, irrigation method, harvesting period, milling procedure, product destination and production results in 2005 and in the...

Integrated Management of European Cherry Fruit Fly Rhagoletis cerasi (L.): Situation in Switzerland and Europe
Provedor de dados: 21
Autores: Daniel, Claudia; Grunder, Jörg.
Abstract: The European cherry fruit fly, Rhagoletis cerasi (L.) (Diptera: Tephritidae), is a highly destructive pest. The low tolerance for damaged fruit requires preventive insecticide treatments for a marketable crop. The phase-out of old insecticides threatens cherry production throughout the European Union (EU). Consequently, new management techniques and tools are needed. With the increasing number of dwarf tree orchards covered against rain to avoid fruit splitting, crop netting has become a viable, cost-effective method of cherry fruit fly control. Recently, a biocontrol method using the entomopathogenic fungus Beauveria bassiana has been developed for organic agriculture. However, for most situations, there is still a lack of efficient and...

Einflüsse des Ackerbohnenkäfers (Bruchus rufimanus) und von Bodenpathogenen auf Feldaufgang und Ertrag bei bunt- und weißblühenden Ackerbohnensorten (Vicia faba)
Provedor de dados: 21
Autores: Saucke, Helmut; Riemer, Natalia; Geßner, Christina; Bacanovic, Jelena; Šišić, Adnan; Finckh, Maria R.
We compared field emergence and yield of a white- and a coloured-flowered variety of faba bean (Vicia faba) in relation to Bruchus rufimanus seed damage in a factorial, hand sown mini-plot field experiment. Further manipulating factors at sowing were, foot root rot inoculation with a 4-species Fusarium-mixture, a seed dressing with powdered testa material of the coloured-flower variety and sowing depth. In both varieties Fusarium-inoculation was the most detrimental and significant factor to field emergence and yield, interacting with a concordant B. rufimanus effect. Expectedly, the white-flowered variety was most affected. Tannin-containing testa meal did not reduce or compensate the impact of fungal inoculation and/or B. rufimanus. We hypothesize that...

Differences between spring wheat cultivars for emergence and early development after seed infection with Fusarium culmorum
Provedor de dados: 21
Autores: Timmermans, B.G.H; Osman, A.M.
Infection of wheat seeds with Fusarium spp. causes seedling blight. As a result of this disease, fields sown with infected seeds show a reduced plant density. This is especially a problem in organic agriculture, for which currently no practical seed disinfection methods are available. In the present project we investigated whether spring wheat cultivars differ in sensitivity to seedling blight, whether the possible differences could be linked to cultivar differences in early growth rates, and what size the delay in canopy closure resulting from the plant reductions was. Six spring wheat cultivars (Melon, Lavett, SW Kungsjet, Epos, Pasteur, Thasos), containing three infection levels (averages 5, 15 and 27%) of Fusarium culmorum were obtained and were sown...

Regulierung von Phytoplasmosen im ökologischen Weinbau - Risikoanalyse und Lösungsansätze
Provedor de dados: 21
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. Auf den ökologisch bewirtschafteten Rebflächen wurden neben Ackerwinde auch Brennnessel und Zaunwinde als...

Krankheitsregulierung im biologischen Kirschenanbau mit neuen Produkten und einer frühzeitigen, vor der Blüte installierten Überdachung
Provedor de dados: 21
Autores: Häseli, Andreas; Weibel, Franco.
Pilzkrankheiten, allen voran die Monilia (Monilia laxa, M. fructigena), stellen ein existentielles Produktionsproblem im Biokirschenanbau dar, stehen doch zu deren Regulierung bislang keine genügend wirksamen Präparate zur Verfügung. Indirekte Massnahmen wie durchlüftungsfördernder Schnitt und konsequente Entfernung der Fruchtmumien können zwar den Krankheitsdruck merklich reduzieren, reichen aber bei den meist stark anfälligen modernen Tafelkirschensorten bei ungünstiger Witterung nicht für eine ausreichende Ertragssicherheit aus.  Diese Umstände bewirken, dass Biobetriebe bislang kaum in den Tafelkirschenanbau investieren und IP-Betriebe mit Kirschenanbau nicht auf Biobewirtschaftung umstellen.  Bei neuen Tafelkirschenanlagen setzen sich aus ökonomischen...

Vinasse: an alternative to lime sulphur for flower thinning?
Provedor de dados: 21
Autores: Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
Thinning trials with vinasse in comparison to lime sulphur were carried out for 4 years  at different sites in South Tyrol. Beside the thinning effect, the influence on fruit  quality, phytotoxic damage on the leaves and the return bloom of treated trees were  evaluated. Depending on the dosage the vinasse treatments showed a good  thinning effect, but russetting and leave damages were significantly higher in  comparison to lime sulphur. Return bloom of vinasse treated trees was lower than of  those treated with lime sulphur. In conclusion, vinasse treatments can not substitute  lime sulphur for flower thinning in organic apple orchards.

Quantification of climate change impacts on agricultural pests
Provedor de dados: 21
Autores: Stöckli, Sibylle; Pierluigi, Calanca.
Temperature is the dominant abiotic factor determining development rates, preproduction and migration of many insects. Climate change will therefore alter population abundance, geographical distribution and seasonal phenology of important agricultural pests. Scenarios concerning possible impacts of climate change on pests are necessary to identify adapted plant protection strategies and sustainable plant management options. Model-based studies are a valuable method for estimating the impacts of climate change on insect pests. Such projections are not easy to develop, because impact models often require a high temporal and spatial resolution of future climate data and long-term field observations are necessary for model calibration and validation.

Provedor de dados: 21
Autores: Kienzle, J.; Zimmer, J.; Volk, F.; Zebitz, C.P.W.
Entomopathogenic nematodes were tested for their potential as tool in resistance  management of codling moth Cydia pomonella L. in organic fruit growing. In two field tests,  the adults emerging from stems treated with nematodes were monitored. In one trial, 90 %  of efficacy could be shown. On-farm trials with favourable weather conditions showed an  efficacy about 50-60 % on fruit infestation by codling moth in the year following the  application. On-farm trials with unfavourable weather conditions showed no results. The  favourable weather conditions for the application are discussed with reference to German  conditions.

Use of genetic resources and partial resistances for apple breeding
Provedor de dados: 21
Autores: Kellerhals, Markus; Duffy, Brion.
Modern apple breeding strategies are mainly considering the most advanced selections and cultivars as parents. This tends to lead to a narrowed genetic basis. The introgression of traditional varieties 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...

Background  The demand for organically produced food is outstripping the ability of UK farmers to supply it and the majority is imported.  Furthermore, there is a major shortfall in home-produced organic cereals and cereal products, including straw.  In response to this need, the consequences of increasing the area of organically produced cereal crops on pests, diseases and weeds require evaluation. Furthermore, as the area of organic cereals increases, crops may be grown more in the major cereal production regions.  This could have consequences for both the organic producer and farmers growing cereals conventionally.

Glucosinolate hydrolysis compounds for weed control
Provedor de dados: 21
Autores: Bellostas, Natalia; Nielsen Kudsk, Per; Sørensen, Jens C.; Sørensen, Hilmer.
Glucosinolates are allelochemicals present in all Brassica plants. Upon hydrolysis by endogenous enzymes they produce a series of biologically active compounds, such as isothiocyanates and their deriva-tives among others. These compounds have marked fungicidal, nematocidal and herbicidal effects and therefore their use as biodegradable natural products for crop protection has attracted much attention in the last years. A number of these compounds, either individually or in combination, were tested against Sinapis alba and Lollium perenne in Petri dishes bio-assays. C50 values as low as 0.7 and 0.2 mM were obtained. This may open the possibility for using glucosinolate hydrolysis products as herbicides.

DL-3-amino-n-butanoic acid (BABA) was effective in controlling downy mildew incited by Bremia lactucae Regel in lettuce plants. The two isomers of BABA, DL-2-amino-n-butanoic acid and 4-amino-butanoic acid and its s-enantiomer were ineffective compares to BABA, while the r-enantiomer was more effective. The SAR compound NaSA and its functional analogue BTH (Bion) were also ineffective compared to BABA. In growth chambers, BABA was effective when applied as a foliar spray or as a soil drench. Effective control of the disease was apparent when BABA was applied up to 5 days before inoculation or 3 days after inoculation.

Vårbygsorters resistens mod stribesyge og nøgenbrand
Provedor de dados: 21

ORGSEED undersøgelserne viser, at der findes en række vårbygsorter med lovende resistens overfor stribesyge og nøgenbrand. Under dyrkningsforhold, hvor de to sygdomme betragtes som nøgle-problemer, burde sortsvalget derfor tager hensyn til de resistensoplysninger, som ORGSEED projektet har tilvejebragt.     Men det skal huskes, at muligheden for at bruge sortsresistens ikke kommer af sig selv. Det kræver stadig årvågenhed med hensyn til at følge skift i sorternes sygdomsreaktion over tid og dette kræver fortløbende resistens-screening og –afprøvning af markedsførte sorter såvel som af forædlingsmaterialet.

Biofumigation auch gegen pflanzenparasitische Nematoden?
Provedor de dados: 21
Autores: Eder, Reinhard; Roth, Irma; Zinsstag, Christof; Koch, Walter.
Biofumigation refers to a biological method to reduce diseases, pests and weeds in  the soil which is suitable for organic production systems. Cruciferous plants with a  high level of Glucosinolates are grown for about two months in the field. To achieve  the biofumigation effect, the intercrop is mulched during full bloom and rapidly  incorporated into the soil. The Gluconisolates are converted during biological  degradation into volatile substances toxic for certain diseases or pests. Nematodes  are also sensitive to these substances and are reduced thereby. Besides using the  incorporation of fresh plant material, pellets made of dried cruciferous plants and sold  as fertilizer might be an alternative approach for nematode control. The pellets are...

Schlagdistanz als Einflussgröße auf den Erbsenwicklerbefall (Cydia nigricana)
Provedor de dados: 21
Autores: Riemer, Natalia; Schieler, Manuela; Saucke, Helmut.
In den Jahren 2016 bis 2018 wurde der Erbsenwicklerbefall in drei ausgewählten Modellregionen in Nordhessen, Sachsen und Sachsen-Anhalt untersucht. Innerhalb der Modellregionen, mit einem Durchmesser von je 30 km, wurde der Befall mittels Pflückproben (Körner aus 100 Hülsen) auf möglichst allen vorhandenen Erbsenflächen erfasst und mit der Distanz zur nächstgelegenen Vorjahresfläche korreliert. Die Ergebnisse zeigen, dass das Befallsniveau, sowohl bei Sommerkörner- als auch bei Winterkörnererbsen bereits bei kleinen Flächenabständen von wenigen 100 Metern bis zu einem Kilometer deutlich gesunken ist. Für eine genauere Risikoanalyse wird der Einfluss weiterer Parametern wie der Schlaggröße und der Anbaudichte diskutiert.

Testverfahren zur Einschätzung des Befallsrisikos komposthaltiger Pflanzsubstrate durch    Trauermücken (Sciaridae)
Provedor de dados: 21
Autores: Kühne, Stefan; Holfert, Maik; Kramer, Eckart.
Growing media for organic farming are increasingly attacked by fungus gnats (Sciaridae) because of their increased microbial activity. Within this study a new method was developed to assess the level of infestation of growing media by the fungus gnat Bradysia difformis (Frey, 1948). The method is based on a comparison of any growing media with two standard substrates. The test method provides the ability to classify growing media in infestation risk classes (low, medium, high) and to test suitable additives, pesticides and bio-control organisms on the fungus gnat infestation.

Bohne ist nicht gleich Bohne
Provedor de dados: 21
Autores: Strube, Jürgen; Stolz, Peter.
Hydrokultur führt bei Bohnen zu höheren Erträgen, ist aber gleichzeitig qualitätsmindernd. Demeter-Saatgut und konventionelles Saatgut wurden jeweils biologisch-dynamisch und in Hydrokultur angebaut.  Die vorliegenden Ergebnisse legen nahe, dass es auch im Pflanzenbau mehr oder weniger artgemäße Anbaubedingungen gibt. Der biodynamische Anbau in Erde erscheint gegenüber der Hydrokultur als weitaus artgemäßer.   Nicht artgemäßer Pflanzenanbau von weißen Bohnen in Hydrokultur prägt sich im Samen ab und lässt sich mit der hier angewendeten empfindlichen Lumineszens-Anregungs-Spektroskopie physikalisch messen und statistisch signifikant von eher artgemäßem biologisch-dynamischen Anbau in Erde unterscheiden.

Sooty blotch of apple: Efficacy of different application strategies
Provedor de dados: 21
Autores: Mayr, U.; Späth, S.
Sooty blotch causes heavy losses in Lake Constance organic apple production. In the last  five years research has been done at the research station for fruit growing  (Kompetenzzentrum Obstbau – Bodensee) on strategies to control Sooty blotch on organic  grown pome fruit. Different control strategies with lime sulphur, coconut soap and  potassium bicarbonate with different application rates, application times were tested in  several trials on the cultivar ‘Topaz’. Over the years the results show that lime sulphur has  significant effects in controlling Sooty blotch. In a first trial potassium bicarbonate showed  a promising efficacy against Sooty blotch. Concerning the right application times we need  further investigations. The problem is that Sooty...

Apple and Pear Cultivars for Organic Production in a Cool Climate
Provedor de dados: 21
Autores: Røen, Dag; Hjeltnes, Stein Harald; Jaastad, Gunnhild.
Only early ripening cultivars of apples and pears may be grown successfully in the short and rather  cool growth season of the fruit producing areas of Norway. Due to a combination of high yield, good  fruit quality and scab resistance, the Swedish cultivar ‘Aroma’ is recommended as major cultivar for  organic apple production today. ’Philip’ is recommended as cultivar for organic pear production.  During 5 years 21 apple cultivars and 15 pear cultivars have been tested in organic orchards in  comparison with ‘Aroma’ and ‘Philip’. Several cultivars in the trial are promising for use in organic  production.

Biogramm und Qualitätskennzahl
Provedor de dados: 21
Autores: Velimirov, Alberta.
The quality assessment and comparison of differently cultivated products still represents a problem. On the one hand “quality” comprises many, mostly target group oriented aspects, necessitating the application of relevant methods, on the other hand the interpretation of diviating results is not easy or suitable to corroborate cultivation dependent quality aspects systematically.   Some scientists have already tried to tackle that problem and developed quality indices by integratig different quality parameters (BREDA 1973, HUBER et al. 1988, SCHULZ &amp; KÖPKE 1997).  The aim of this presentation is to reach a grafic and numeric interpretation of results obtained from different methods. Although organic quality research corresponds to the holistic...

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
Autores: Weitbrecht, Karin; Schmidt, Carsten; Kassemeyer, Hanns-Heinz.
Kupfer ist ein vor allem in der ökologischen Landwirtschaft und dort viel in Sonderkulturen eingesetztes Pflanzenschutzmittel. Gerade in großflächigen Sonderkulturen wie Wein, Apfel oder Hopfen wird Kupfer im ökologischen Anbau gegen spezifische Krankheitsbilder erfolgreich eingesetzt: z.B. den Falschen Mehltau des Weins bzw. des Hopfens und den Erreger des Apfelschorfs (Venturia inequalis).  Der Einsatz von Kupfer als Pflanzenschutzmittel führt zu einer Anreicherung dieses Schwermetalls in den Böden. In Weinbergsböden wurde gezeigt, dass die Belastung Auswirkungen auf alle im Boden lebenden Organismen (Bodenzönose) und auch Kleinsäuger und Vögel haben kann. Große Kupfermengen führen zu einer reduzierten Biodiversität, was dem ökologischen Gedanken direkt...

Greenhouse-Experiments on control of Venturia inaequalis - First Results
Provedor de dados: 21
Autores: Pfeiffer, Barbara.
Based on the encouraging results of the diploma thesis from Sibylle Späth in 2000, a series of experiments in the greenhouse followed in 2001 to test different extracts from medicinal plants against apple scab. The seedlings of the variety 'Golden Delicious' were infected artificially by spraying a suspension of conidia from scab-infected leaves from the orchard. The plant extracts were compared with copper-hydroxid. A few extracts seem to be successful against apple-scab. In the future further experiments in the greenhouse and in the orchard will follow to confirm the promising results and to find more information about side effects like phytotoxity, russeting or thinning.

European tarnished plant bug (ETB) sex pheromone traps in Norwegian strawberry must be deployed very early in the season to maximize catches. To trap females or the new generation, other attractants must be added.  The strawberry blossom weevil attractant PV2 may act as a slight antagonist in ETB trapping, especially early in  the season.

Provedor de dados: 21
Autores: Wibe, Atle; Apenite, I; Baroffio, Catherine; Borg-Karlson, Anna-Karin; Cross, J; Sigsgaard, Lene.
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 strawberry.     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.

Generalistiska predatorer: en studie av predation, födoval och konkurrens på ekologiska och konventionella gårdar
Provedor de dados: 21
Spindlar och jordlöpare är generalistiska predatorer som bl.a. äter skadeinsekter. Tidigare studier har visat att predationen på nyinflugna havrebladlöss är högre på ekologiska gårdar jämfört med konventionella samt i småskaliga system med mycket vallodling. Tänkbara förklaringar till den lägre predationen i konventionella och/eller storskaliga, ettåriga odlingssystem är lägre tillgång till alternativa byten och högre förekomst av predation mellan olika naturliga fiender. Predation kan studeras på flera olika sätt. En metod är detektion av bytes-DNA i predatorernas maginnehåll med hjälp av PCR. Syftet med detta projekt är att i olika odlingssystem studera och jämföra 1) predationen på havrebladlusen 2)predationen på och betydelsen av alternativ föda, 3)...

Integrated disease management
Provedor de dados: 21
Autores: Köhl, Jürgen.
Integrated disease management in organic farming combines the use of various measures. The usefulness of certain measures depends on the specific crop-pathogen combination. In many crops, preventative measures can control diseases without the need of plant protection products. However, for certain disease problems, preventative measures are not sufficient. For example, organic apple production strongly depends on the multiple use plant protection products.

Qualitätsoptimierung von Bio-Substraten für die Jungpflanzenanzucht im ökologischen Gemüseanbau unter besonderer Berücksichtigung der Praxisumsetzung des Torfersatzes durch fermentierte Holzfaser
Provedor de dados: 21
Die Jungpflanzenanzucht und die Substratproduktion wurden in den letzten Jahren vermehrt in Spezialbetriebe ausgelagert.

Autores: Lambion, Jérôme; Laur, Mathieu.
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 produits alternatifs au soufre, toxique contre les auxiliaires. L’essai réalisé cette année avec le même protocole...

Autores: Daniel, Claudia; Schärer, Hans-Jakob; Cahenzli, Fabian.
Die Kirschessigfliege (Drosophila suzukii) wurde 2008 aus Südostasien nach Europa einge-schleppt 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. Ho-lunder und Schneeball dienen als Wirtspflanzen. Der Hauptschaden entsteht durch den Larven-frass 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 Trauben 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 im Jahr 2014 erstmals starke...

Fazit  Die Mineralstoffgehalte von 12 Sorten Eis- und Kopfsalat aus biologisch-dynamischem Anbau wiesen starke inverse Beziehung zu den ebenfalls sehr unterschiedlichen Kopfgewichten auf, da vermutlich das Wachstum von Kopf und Wurzeln nicht im Gleichgewicht steht. Innenbrand stand in starker Beziehung zu den Ca-Gehalten, wenn die Kopfgewichte in die Betrachtung einbezogen wurden. Speziell die biologisch-dynamische Züchtung sollte sowohl mit Blick auf den Innenbrand als auch die Nahrungsqualität nicht nur das Wachstum des oberirdischen sondern auch des unterirdischen Teils der Salatpflanze fördern.

Övervakning och hållbar bekämpning av morotsbladloppan: ekologisk produktion och säker barnmat
Provedor de dados: 21
Morotsbladloppan, Trioza apicalis (Hemiptera: Homoptera), är en allvarlig skadegörare på morötter i norra Europa. För närvarande finns ingen tillförlitlig övervakningsmetod och upprepad användning av kemiska insekticider (upp till åtta gånger per odlingssäsong) gör att risken för resistensutveckling är påtaglig. I många områden är morotsbladloppan den enda skadeinsekten av betydelse. Om de negativa effekterna av denna art reduceras kan därför ett stort antal odlare förväntas gå över till ekologisk odling. Morötter odlas i vissa områden speciellt för barnmatsproduktion. Reglerna för tillåtna restprodukter av bekämpningsmedel i barnmat har nyligen skärpts, vilket gör att producenterna i princip måste använda råvaror som inte besprutats. I detta projekt...

Autores: BEN MOSBAH, Amira.
Lobesia botrana is the key pest of vineyard, it presents two to five generations per year which cause a direct damage to grapes by perforating berries and an indirect damage by favoring the installation of rot fungi like Botrytis cinerea. In organic vineyard, L. botrana is biologically controlled by means of predators and parasitoids. For this purpose, field survey, monitoring and sampling were conducted in five different farms in Apulia region as in Tunisia in order to identify the predators and parasitoids of Lobesia botrana. The continuous sampling of nests and infested berries showed in Apulia farms the presence of predators that belong to the order of: Neuroptera, Dermeptera, Orthoptera and Arachnida. The parasitoids found belong to the Diptera order,...

Biodiversität fördern und nutzen – Schädlingsbekämpfung im Kohlanbau
Provedor de dados: 21
Autores: Luka, Henryk.
In cabbage fields parasitoid wasps (Hymenoptera) use the eggs or larvae of pest butterflies and moths for their own reproduction, ultimately killing them. In this way these parasitoids play 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, 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).

Advances in the knowledge of quinoa pests
Provedor de dados: 21
Autores: Rasmussen, Claus; Lagnaoui, Aziz; Esbjerg, Peter.
A wide range of quinoa pests are known throughout the world. The most serious of the Andean pests are Eurysacca melanocampta (Meyrick) and E. quinoae Povolny´ (Lepidoptera: Gelechiidae), found mainly in Peru and Bolivia, which cause considerable yield losses. Insects found elsewhere in the world are polyphagous pests constituting a wide range of potential pests if quinoa is implemented as a crop in those regions. Other major pests include a group of cutworms (Noctuidae). Apart from insects birds cause a major loss through foraging, damaging cotyledonous plants and inflorescences, with yield losses of up to 60%. Cultural practices and host plant resistances will be important components of integrated pest management (IPM). Biological control of the main...

Autores: Theodoropoulou, A.; Giotis, C.; Hunt, J.; Gilroy, J.; Toufexi, E.; Liopa-Tsakalidis, A.; Markellou, A.; Lueck, L.; Seal, C.; Leifert, C.
Soil-borne diseases are one of the most important problems in organic and other ‘low input’ soil-based greenhouse production systems. While chemical soil disinfection has been the method of choice in conventional farming systems, soil steaming has been the main strategy for the control of soil borne diseases in organic production. Both methods are extremely expensive and have been increasingly restricted for environmental reasons by government and organic standard setting bodies respectively.  The use of tolerant varieties and of grafting onto resistant rootstocks were evaluated as potential replacements for soil steaming in organic and low input systems and found to be as effective in reducing root disease and increasing root fresh weight, fruit yield and...

Autores: Lambion, Jérôme; Bertrand, Cyril.
A trial was established in 2003, in Southern France, to assess under organic farming conditions the effect of top irrigation with sprinklers on potato yield, but also to evaluate side effects on epidemics, with a focus on late blight (Phytophthora infestans L.). Two varieties, one susceptible (Charlotte) and one with a good level of resistance to late blight (Eden), have been planted. Three irrigation regimes have been applied : no irrigation [NO], reduced or optimized irrigation [OPT] and irrigation according to usual grower practice [NORM]. Irrigation had no effect on foliar late blight development. For both varieties, commercial yield in the non-irrigated plots was significantly lower (16,36 t.ha-1) than in the OPT and NORM plots (resp. 26,12 t.ha-1 and...

Visual ecology of aphids – a critical review on the role of colours in host finding
Provedor de dados: 21
Autores: Döring, Thomas F.; Chittka, Lars.
We review the rich literature on behavioural responses of aphids (Hemiptera: Aphididae) to stimuli of different colours. Only in one species there are adequate physiological data on spectral sensitivity to explain behaviour crisply in mechanistic terms.   Because of the great interest in aphid responses to coloured targets from an evolutionary, ecological and applied perspective, there is a substantial need to expand these studies to more species of aphids, and to quantify spectral properties of stimuli rigorously. We show that aphid responses to colours, at least for some species, are likely based on a specific colour opponency mechanism, with positive input from the green domain of the spectrum and negative input from the blue and/or UV region.

Winter treatments against the woolly apple aphid (Eriosoma lanigerum): products and timing of applications
Provedor de dados: 21
Autores: Kelderer, Markus; Lardschneider, Ewald; Casera, Claudio.
In organic apple growing the woolly apple aphid (Eriosoma lanigerum) is still an unsolved  problem. Various approaches to use beneficial insects were not really effective. Only  winter treatments with mineral oils showed partial and fluctuating success.  In 2006 and 2007 field trials were carried out to evaluate the efficacy of winter treatments  to control woolly apple aphids. The efficacy of several products (different mineral oils, lime  sulphur, and lime sulphur + mineral oil) was tested in comparison to an untreated control,  and possible side effects on the population of predatory mites were investigated. The  study furthermore aimed at establishing the best timing of the application against the target  pest.

Three organic systems on medium silt soil; stockless system with benefit of pig manure; with associated outdoor pigs
Provedor de dados: 21
Conversion of farming systems from conventional to sustainable organic production (according to UKROFS standards) initially involves a 2 year fertility building phase. This study will aim to investigate the costs and potential problems associated with conversion of conventionally farmed land to production under organic standards. The study will involve measurement of physical and financial inputs and outputs during the conversion of an experimental farming system to organic production. 16 hectares of fertile soil will be converted to 3 organic management systems (stockless, pig manure, stocked with outdoor pigs) producing organic potatoes and cereals for sale, cereals and pulses for home consumption and clover/leys for mulching or stocking with pigs....

The Control of Stem Blight and the Spread of Potato Late Blight by Copper Seed Treatment
Provedor de dados: 21
Autores: Zellner, Michael; Keil, Sven; Benker, Marianne.
Late blight still is an unsolved problem in organic potato farming. Up to now the most effective way to control this disease is the use of copper fungicides. Transferring results from regular farming, seed treatments with copper fungicides shall postpone the beginning of the blight epidemic and decrease the spread of the disease with soil water. Thus stem blight, which can’t be prevented otherwise, shall be reduced. In field trials, conducted 2005-2007, copper fungicide treatments reduced primary stem infections (stem blight) and the spreading of the pathogen from infected seed tubers.

Mechanical weed control for integrated and organic salad and brassica production
Provedor de dados: 21
Diminishing herbicide options, fear of ground water contamination and customer pressure to minimise herbicide use are all pushing the industry away from reliance on herbicides.  However, product contamination concerns, much of which relate to weeds, necessitate high levels of weed control and have resulted in increasing use of unsustainable hand weeding. A major constraint to continued growth of processed bagged salads is contaminants. Major contaminants are weeds and weed seeds, however other pest and disease contaminants are enhanced by poor weed control. The majority of salad crops are hand weeded once and some twice at a cost of £400-£1000/ha depending on weed levels. This task is not liked and leads to back problems.   Brassica production is also...

Selection of antagonists suppressing conidia production of Venturia inaequalis
Provedor de dados: 21
Autores: Köhl, J.; de Haas, B.H.; Molhoek, W.M.L.
Novel antagonists for biological control of Venturia inaequalis causing apples scab were screened. Several hundred fungal isolates were obtained from sporulating colonies of V. inaequalis on apple leaves collected at various locations. Candidate antagonists were pre-screened to exclude those isolates with potential risks or low economical feasibility. Remaining isolates were tested on apple seedlings for their ability to reduce conidiation of V. inaequalis. Several promising antagonists could be selected and will be tested under field conditions in summer 2006.

Control of the appleseed moth Grapholita lobarzewskii Ragonot in organic fruit  growing
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.

In den Jahren 2004 bis 2006 wurden in einem Forschungsprojekt Alternativen zur An-wendung kupfer- und schwefelhaltiger Pflanzenschutzmittel im Ökologischen Hofenbau gesucht. Besonderes Augenmerk galt dabei der Peronospora (Falscher Mehltau), die bis dato nur mit kupferhaltigen Produkten effektiv kontrolliert werden kann, sowie der Hop-fenblattlaus. Zur Bekämpfung der Peronospora wurden insgesamt zehn Produkte oder Varianten zum Teil über drei Saisons geprüft. Als Fazit der Versuche konnte kein kupfer-freies Produkt gefunden werden, das auch nur annähernd die Peronospora im Hopfen be-kämpfen kann, da diese ohne Ausschaltung der Primärinfektion mit rein biologischen Pro-dukten nicht effektiv kontrolliert werden kann.

Grain dryer for organic farming
Provedor de dados: 21
No seed dressing substances are allowed in organic farming. Smoke dressing would be an acceptable method. Smoke dressing was practised in the old-time drying barns. In this project we imitate this old method with a modern, conventional hot air dryer. A portable heating unit fuelled with wood chips is connected to a conventional hot air dryer. The adjustments of the drying-smoking process are studied, and different fuels are tested. The wood chip heating unit is also tested as such, separate from the dryer.

Primary roots and shoots of 13 day old cereal seedlings and quality of seed were  investigated in the frame of the certification process of organic seed produced in  Austria. The germination of seed and the development of seedlings were significantly  affected by Microdochium nivale on wheat, triticale and rye and by Septoria nodorum  on wheat. The number of primary roots was found to be significantly different in wheat  varieties and genotypes but was not influenced by year and region. The number of  primary roots was also positively correlated with the kernel weight of some wheat  varieties.

Autores: Caleca, Virgilio; Rizzo, Roberto.
Repellent and antiovipositional products in the control of Bactrocera oleae (Gmelin) find a great interest in organic farming, because of the lack of effective products able to kill the olive fly preimmaginal stages.  In 2003 in Castelvetrano (Trapani province, Sicily), tests on the effectiveness of Surround WP, a product containing 95% of kaolin, were carried out on three table olive cultivars, Nocellara del Belice, Moresca and Tonda Iblea. In 2004, in the same field and on the same cultivars, BPLK kaolin was tested too. In the second year the two products containing kaolin were also tested on Cerasuola cultivar in an organic olive grove located in Trapani, comparing them with copper hydroxide.

Copper reduction and copper replacement - results and experiences of 12 years of on farm research
Provedor de dados: 21
Autores: Hofmann, Uwe.
Copper is a very common pesticide in organic viticulture, used against different diseases. But it is long term toxic for soils. That is why organic winegrowers try to reduce its use. Since 1988 ECO-Consult and the Organic Winegrowers Association of Germany (BÖW) has coordinated a on farm research program concerning copper reduction in organic vine protection.   As a result of this reseach, the document outlines a plant protection strategy against Plasmopara viticola (downy mildew).  Tables:  - Use of Copper (kg/ha/a) by german organic wine growers in 1996 to 1998  - Frequency of Plasmopara viticola infection on clusters in the years 1990 to 2000 (ring trial - on farm research)

Autores: Schmidt, Harald; Hallmann, Johannes.
Evaluating the problem of spotwise appearing cereal growth depressions 23 fields of 10 organic managed farms were investigated. Potential causes were soil nutrients and other chemical and physical soil properties as well as high abundance of the plant parasitic nematodes Heterodera avenae and Pratylenchus-, Tylenchorhynchus and Trichodorus species. In two on-farm field experiments different catch crops and a black fallow treatment caused a decrease of Pratylenchus and Tylenchorhynchus species. However, the yields of the following spring wheat were low, possibly due to H. avenae infestation. Fertilization with compost and potassium had no effect but the H. avenae resistant variety Isotta produced much higher yields. The conclusion drawn was that farmers...

NATURAL PRODUCTS ALONE OR WITH COPPER VS. GRAPE DOWNY MILDEW: EFFICACY, COSTS, CU IMPACT
Provedor de dados: 21
In organic farming copper is one of the few fungicides that can be used and the only effective against downy mildew.  Due to the problems of environmental impact associated with the use of this heavy metal, the European Union decided to restrict its use (Annex II Regulation EC n. 889/2008). In order to assess the possibility of replacing the copper or reduce the quantities used, we tested natural products and low rate copper formulations in field trials.   The anti-downy mildew activity of these formulations has been studied in an organic vineyard. During the two years of activity we also estimated the economic cost of use of the products to assess their possible use in agricultural practice.  The examined products were:   homeopathic products...

L'Inra d'Avignon, le Grab et la Sonito (Société Nationale Interprofessionnelle de la Tomate) participent à un programme commun dont le thème principal est la recherche d'alternatives au cuivre. Dans la lutte contre les bactérioses de la tomate, le niveau de protection apporté par différentes formulations de cuivre en dose réduite (4 applications de 1kg par hectare) s'avère insuffisant pour permettre un contrôle satisfaisant des attaques. La suppression des traitements au cuivre, contre le mildiou de la tomate, est préjudiciable à la culture, même pour la variété résistante observée (taux de mildiou de 20 % sans cuivre contre 0 et 5 % avec cuivre).

A range of studies have compared the level of nutritionally relevant compounds in crops from organic and nonorganic farming systems, but there is very limited information on the effect of farming systems and their key components on the protein composition of plants. We addressed this gap by quantifying the effects of different farming systems and key components of such systems on the protein profiles of potato tubers. Tuber samples were produced in the Nafferton factorial systems study, a group of long-term, replicated factorial field experiments designed to identify and quantify the effect of fertility management methods, crop protection practices and rotational designs used in organic, low input and conventional production systems.

The effect of autumn ridging and inter-row subsoiling on potato tuber yield and quality
Provedor de dados: 21
Autores: Henriksen, Christian Bugge; Mølgaard, Jens Peter; Rasmussen, Jesper.
Autumn ridging is a modified version of the ridge tillage system. Instead of setting up ridges during the growing season, they are established in autumn and left for the winter. Previous studies have documented positive effects of autumn ridging on potato yield and we hypothesize that applying subsoiling could enhance these effects. To determine the effect of autumn ridging and inter-row subsoiling on potato yield and quality a field experiment was conducted on sandy soil from 2001-2003. Autumn ridging showed comparable yields to ploughing and significantly reduced the incidence of black scurf from 2.5% to 2.2%. Inter-row subsoiling in the growing season significantly increased marketable potato tuber yield from 84.4 hkg/ha to 96.3 hkg/ha and reduced the...

Improving quality and safety and reduction of cost in the European organic and ‚low input’ food supply chains (Quality Low Input Food (QLIF)  Work package 3.1 Identifying soil management practices which optimize soil quality characteristics (mineralization capacity and diseases suppressiveness)
Provedor de dados: 21
An important characteristic of organic and “low input” production systems is the more frequent use of manure and other organic matter based fertility inputs (e.g. green manures, composts). This and the prohibition (in organic systems) or reduced use (in other “low input” systems) of soil pesticides is thought to result in environmental, biodiversity and/or agronomic benefits. For example, soil biological activity, earthworm number/bio-mass, soil aggregate stability, organic matter content, erosion resistance and the ability of soils to release soil pools of nitrogen were all shown to increase under organic management and/or in soil which receive regular organic matter inputs (Mäder et al. 2002; Drinkwater et al. 1998; Reganold et al. 2001, Langmeier et al....

Reduction of Soil-Borne Plant Pathogens Using Lime and Ammonia Evolved from Broiler Litter
Provedor de dados: 21
Autores: Fine, P.; Roded, L.; Cohen, S.; Shapira, N.; Adler, U.; Or, N.; Ben-Yephet, Y.; Reuven, M.; Oka, Y.
In laboratory and micro-plots simulations and in a commercial greenhouse, soil ammonia (NH3) and pH were manipulated as means to control soil-borne fungal pathogens and nematodes. Soil ammonification capacity was increased by applying low C/N ratio broiler litter at 1–8% (w/w). Soil pH was increased using lime at 0.5–1% (w/w). This reduced fungi (Fusarium oxysporum f. sp. dianthi and Sclerotium rolfsii) and root-knot nematode (Meloidogyne javanica) in lab tests below detection. In a commercial greenhouse, broiler litter (25 Mg ha−1) and lime (12.5 Mg ha−1) addition to soil in combination with solarization significantly reduced M. javanica induced root galling of tomato test plants from 47% in the control plots (solarization only) to 7% in treated plots....

An increasing literature body is devoted to the study of efficacy and risks concerning compounds allowed in organic farming and new compounds considered harmless for environmental and human health. The great biodiversity inhabiting olive agroecosystem lead to a biotic control of many pest species. The only widespread pest causing economic damages is the olive fly, Bactrocera oleae. The side effects of compounds allowed against the olive fly in open field are still little known as well as the agronomical methods for mitigating them. The aims of this research were to evaluate the impact of compounds allowed in organic olive farming and searching for more ecocompatible farming strategies.

Auswirkungen der Sortenmischungsstrategie auf Backqualität,Ertrag und Krankheitsbefall im Winterweizen
Provedor de dados: 21
Autores: Finckh, Maria R.; Schulze-Schilddorf, Georg; Pawelzik, Elke.
Ziel der Arbeit ist es, die Auswirkungen von Sortenmischungen bei unterschiedlicher Nährstoffversorgung auf Backqualität, Ertrag und Krankheitsbefall im Ökologischen Landbau zu überprüfen.   Die Ergebnisse der Versuche legen nahe, daß Interaktionen zwischen Standortbedingungen, Jahr und Sorte sehr groß sind aber insgesamt die Mischungen die Backqualität nicht beeinträchtigen. Die Datenbasis ist aber für die Formulierung von Empfehlungen nicht  breit genug. Um den Einfluß von Standortfaktoren und Mischungen auf Krankheitsbefall, v.a. Fusariosen, Backqualität und Mykotoxin-belastung zu quantifizieren wurden für 2002/2003 Praxisversuche an 12 Standorten mit Reinbeständen und Mischungen angelegt.

Autores: Caleca, Virgilio; Lo Verde, Gabriella; Lo Verde, Valentina; Palumbo Piccionello, Manuela; Rizzo, Roberto.
Tests on the effect of clays (kaolin and bentonite) and copper products  (hydroxide and oxychloride) in the control of olive fruit fly, Bactrocera oleae (Rossi), and Mediterranean fruit fly, Ceratitis capitata (Wiedemann), were carried out from 2003 to 2006 in olive groves and in organic citrus orchards (satsuma, clementine, ‘Navelina’ orange). Results demonstrate an efficacy of kaolin products in reducing attacks of B. oleae on olives and those of C. capitata on citrus fruits; in olive groves the clays gave similar or better results than copper hydroxide. Bentonite AG/8W showed a significant reduction in punctures by C. capitata. Bentonite products and BPLK kaolin are washed off by rainfall more easily than Surround WP kaolin.

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 melanotoma (form. caliginosus) 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)....

L’anthonome des framboises (Anthonomus rubi) et le ver des framboises (Byturus tomentosus) causent de grosses pertes dans les cultures biologiques de framboises. Dans le cadre du projet européen Core Organic 2, le projet «Softpest Multitrap» a testé une nouvelle approche pour controller simultanément ces deux ravageurs avec un piège commun, afin de proposer une alternative aux insecticides. Le but a été de définir la hauteur du piège, son design et lacombinaison de leurres optimale. Nos essais ont montré que le piège doit être posé au sol en combinant une aggregation de phéromones et des composés volatils de fleurs de framboisier pour capturer ces deux insectes. Les pièges doivent être mis en place dès le départ de la végétation (stade BBCH 45–47). Le...

Provedor de dados: 21
Autores: Köppler, Kirsten; Storch, Volker; Vogt, Heidrun.
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 %.

This study has improved our understanding of the phenology of the three species, which is of key importance to determine the timing and positioning of traps. Lure duration is one of the bottlenecks in designing commercially viable insect traps for monitoring or mass trapping. Our results emphasize that traps intended for more than one species and region either need long-lasting lures to cover all possibilities, or detailed knowledge about local conditions (e.g. prevalence of pest and surrounding host plant species etc.) to apply lures at the right time

Autores: Tamm, Lucius; Speiser, Bernhard; Mercier, Thierry.
Plants and plant extracts, here called 'botanicals', have been used for plant protection for a long time. Quantitatively, the most important botanical is pyrethrum, followed by azadirachtin, rotenone and essential oils. The current regulatory systm for pesticides is often seen as a major hurdle for the market introduction of new botanicals. The EU-funded Specific Support Action project 'REBECA' has held a series of workshops with stakeholder representatives. The following propopsals for improvement were elaborated: (1) development of a specific guidance document for botanicals; (2) adapted requirements concerning the characterisation of the active substance(s); (3) relaxations concerning identification and analytical methods for 'impurities'; (4) adapted...

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 effi-cacy on secondary infestation. Thus, even if due to difficult conditions during application or not optimal ter-mination of the treatment the efficacy on the primary infestation is not entirely sufficient, the secondary in-festation will be controlled better.

The aim of this study was to evaluate the efficacy of old and new copper formulations to control downy mildew Plasmopara viticola (Berk. et Curtis) Berl. et. De Toni). Field trials were carried out over the years 2002, 2004 and 2005 in a grapevine  growing area in the Po Valley with a high disease pressure. Among the traditional copper formulations, hydroxide-based products gave the best results. Other new copper formulations, including foliar fertilizers, simple adjuvants and resistance inducers were evaluated. In particular, resistance inducers with a low percentage of copper gave promising results even though some of them show some phytotoxic problems.

Nectria galligena as the cause of a collar rot disease in organically grown Topaz apple trees
Provedor de dados: 21
Autores: Weber, Roland W. S.; Klopp, Karsten.
Symptoms resembling collar rot were detected in organically managed Topaz trees aged 3-10 years, occur-ring one to several years after planting of the orchard. Trees were killed within the same growing season in which symptoms were first observed. The disease commonly progressed as a complete covered canker at the base of the tree trunk. Isolation attempts were negative for Phytophthora and other Oomycetes, but con-sistently yielded Nectria galligena. The possibility of latent (endophytic) infections of N. galligena as the cause of delayed collar rot symptoms is briefly discussed.

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 (notamment la faible efficacité des traitements à base de cuivre).

Synthetic crop protection agents play an essential role in the protection of plants or harvested fruits against microorganisms. They are effective and economically advantageous but, by modern standards, they lack selectivity and applied at high rates they are threat to human health and environment. Complying with the growing public awareness of these hazards, increasing emphasis is placed upon the search for novel, natural products with pesticidal activity. Phenolic compounds, present in the olive fruit, definitely belong to this group.

Um den Einfluss von Kompost und Gärgut auf die Bodenfruchtbarkeit und auf das Pflanzenwachstum abschätzen zu können wurden hundert, für die Schweiz repräsentative, Proben untersucht.  Die Gehalte an Nährstoffen und an Salz waren vom Ausgangsmaterialien abhängig. Die Gehalte an organischer Substanz sowie die Atmungs- und Enzymaktivitäten nahmen mit zunehmender Kompostreife ab. Bei einigen jungen Komposten konnten Stickstoffblockaden beobachtet werden. Der Nitratgehalt im Kompost erlaubt jedoch vorherzusagen, ob eine N-Immobilisierungsgefahr besteht oder nicht. Die Phytotoxizität der Komposte variierte auch bei den reiferen Produkten sehr stark. Dies weist auf die grosse Bedeutung der Rotteführung und der korrekten Lagerung der Produkte hin. Während die...

Multiple diseases, host resistance and the role of variety mixtures for disease control in organically grown spring barley
Provedor de dados: 21
Autores: Pinnschmidt, Hans; Vollmer, Jeanette H.; Hovmøller, Mogens S.; Munk, Lisa; Østergård, Hanne.
The presence of more than one disease at the same time is common in farmers’ fields. The use of disease resistant varieties is one of the most important disease management components in organic farming. While many modern spring barley cultivars possessing good resistance to individual diseases are available today, cultivars resistant to multiple diseases are still scarce because breeding for multiple disease resistance is a difficult and lengthy task. Mixing cultivars possessing high levels of resistance to individual diseases may be a good option to control multiple diseases in ecological farming. Research is underway in Denmark in which the effects of resistance properties of spring barley varieties on the development of two important foliar diseases,...

Late blight in organic potato growing: managing resistance and early tuber growth
Provedor de dados: 21
Autores: Hospers - Brands, Monique; Timmermans, Bart; van der Putten, Peter; Struik, Paul; Tiemens-Hulscher, Marjolein; Lammerts van Bueren, Edith.
In organic potato production yields are often reduced by potato late blight (Phytophthora infestans). Two aspects are important in late blight management: a sufficiently high (field) resistance to late blight, and early tuber formation. With early tuber formation the period of tuber growth is extended at the beginning, and with a high resistance level at the end.   In 2006 and 2007 experiments were carried out in which the effects of the physiological age of seed tubers on field resistance to late blight and on tuber yield of potatoes (Solanum tuberosum L.) were tested for early and moderately late varieties. The results indicate that with the use of physiologically older seed tubers (by pre-sprouting) the field resistance to late blight is generally lower...

Examples of alien pathogens in Finnish potato production - their introduction, establishment and consequences
Provedor de dados: 21
Autores: Hannukkala, Asko O.
Most pathogens on potato have been imported into Finland via contaminated seed more than hundred years ago. The history of migration and the consequences for potato production of potato wart, blackleg and soft rot, Potato mop-top virus (PMTV) and its vector powdery scab are reviewed as examples of economically important and biologically different potato pathogens. Potato wart spread alarmingly during 1920-1960. Plant quarantine acts and the use of resistant cultivars were successful in eradicating the disease. The pathogens causing blackleg and soft rot increased rapidly in 1960-1970. Development of seed certification schemes after the end of the 1970s decreased disease incidence and made the disease insignificant other than for seed potato production....

Karotten sind eine wichtige Kultur im Biologischen Anbau. Im Vergleich zu anderen Gemüsearten weisen Karotten einen überproportionalen Bioanteil im Verkauf. Für Landwirtschaftsbetriebe sind sie anderseits ein wichtiger Ersatz von Zuckerrüben und Raps in der Fruchtfolge.    Das wichtigste Anbauproblem sind Alternariakrankheiten am Blatt und an der Wurzel. Die wichtigsten Gegenmassnahmen sind, neben einer weiten Fruchtfolge (mindestens 4 Jahre Anbaupause) und möglichst windoffenen Lagen, robuste Sorten und gesundes Saatgut sowie bei  starkem Befall die direkte Regulierung mit Kupferpräparaten.    Bereits im Jahr 2003 wurden an der Strafanstalt Wauwilermoos Versuche mit behandeltem Saatgut durchgeführt. Dabei wurde das Saatgut mit Milchsäure behandelt. In...

Provedor de dados: 21
Autores: Asser, Sabine; Gund, Nadine A.; Eberle, K. E.; Matt-Schmid, A.; Reineke, Annette; Heckel, David G.; Zebitz, Claus P. W.; Jehle, J. A.
The Codling moth granulovirus (Cydia pomonella granulovirus, CpGV, Baculoviridae) is one of the most important bio control agents of the codling moth in apple production. Since 2003, codling moth populations have been observed in Germany and France, which show an up to thousand fold decreased susceptibility to CpGV. A spread of this phenomenon is a severe threat to the efficient control of the codling moth, particularly in organic farming. In order to prevent this development, investigations on the popula-tion genetics of codling moth populations in Germany were initiated to assess the baseline susceptibilities of selected populations. Furthermore, the genetic and biologi-cal background of resistance of the codling moth to CpGV are being elucidated by...

The consistently superior quality of carrots from one organic farm in Austria compared with conventional farms
Provedor de dados: 21
Autores: Velimirov, Alberta.
The aim of this 5 year investigation was to compare quality parameters of differently cultivated carrots of the same cultivar grown in the same region as well as to compare the relevance of different methods of analysis to differentiate between these products.  The following quality tests were applied:   • Sensory tests (all harvests)  • Food preference tests with laboratory rats (all harvests)  • Decomposition tests (all harvests)  • P-value determination (all harvests)  • Single-Photon-Counting (1999)  • Chemical analysis of the main components (1998 and 1999)  It could be shown that carrots (var. Tarvil) grown using an organic farming method were significantly preferred by humans and laboratory rats, lost significantly less dry matter during...

Looking for ecological control of carrot psyllid
Provedor de dados: 21
Autores: Nissinen, Anne.
The results suggest that a one-week trap replacement period, which is the current practise in carrot psyllid monitoring, is too long at the early growth stages of carrot. Regardless of the oviposition (laying of eggs) preference for a certain carrot cultivars, the possibility of a functional push-pull control strategy based on limonene seems unlikely, since the repellent effect of limonene could not be verified. Further field studies with possible repellent compounds, such as winter host volatiles, will be needed to develop an efficient ecological control method for this species.

The use of mulch to increase Spider (Arachnidae) numbers; a habitat approach to biological insect control
Provedor de dados: 21
Autores: Manns, Mrs. Hida R.; Murray, D. L.; Beresford, D. V.
The potential for insect predators to contribute to a biological balance of insect species was explored with mulch.  Insects were collected in pitfall traps in outdoor microplots over 3 seasons in southern Ontario, Canada.  Treatments varied each season with crops of oats or soybeans, with residue of straw, corn stalks or paperfibre, and with residue tilled in or surface applied.  In 2006 at the peak of spider population density there was a significant effect of the plant and the paperfibre residue on increasing spider density. Existing data sets on spiders by Spiller and Schoener (1988 &amp; 1994) were analyzed to assess the potential to increase spider survival from improved carrying capacity of their habitat.  Spider census data was tested with curve...

Quantitative relationships in the infection cycle of seed-borne net blotch
Provedor de dados: 21
Autores: Pinnschmidt, H.O.; Nielsen, B.J.; Hansen, H.J.
Seed-borne net blotch is a threat to organic barley seed production in Denmark because it often exceeds the recommended 15% contamination threshold in barley seed lots. This threatens the supply of organic barley growers with organically produced healthy barley seeds. The ORGSEED project aims at quantifying the links between initial seed contamination, primary seedling infection, disease severity during the growing season, yield parameters and new contamination of the harvested grains to improve decision support for handling net blotch contaminations in organic barley- and barley seed production. The harvested grains of spring barley varieties grown at several sites in Denmark in 2002 and 2003 were used as seed lots in subsequent trials in 2003 and 2004....

What do we (need to) know about low-susceptibility of codling moth against Cydia pomonella granulovirus (CpGV)!
Provedor de dados: 21
Autores: Jehle, Johannes A.; Sayed, Samy; Wahl-Ermel, Britta.
In 2005, the first codling moth (CM) populations with a reduced susceptibility to Cydia pomonella granulovirus  (CpGV) products have been observed. This phenomenon might be an indicator of an emerging resistance of  CM to CpGV. This paper summarizes some aspects of CM CpGV interaction and discusses potential  mechanisms in the host virus interaction, which could contribute to the observed low susceptibility. In order to  develop and implement successful resistance management strategies, much more knowledge about the  plasticity of CM CpGV interaction and the diversity of CM populations is essential.

Autores: Thuerig, Barbara; Ramseyer, Justine; Hamburger, Matthias; Ludwig, Mathias; Oberhänsli, Thomas; Potterat, Olivier; Schärer, Hans-Jakob; Tamm, Lucius.
In organic agriculture, the control of several diseases is largely depending on copper fungicides. Yet, copper can accumulate in the soil if the annual input exceeds annual uptake by plants, which can have a negative impact on soil fertility. Its use should thus be avoided or reduced. The aim of the present study was to evaluate the efficacy of a bark extract of Magnolia officinalis Rehder and Wilson to control three pathogens including Plasmopara viticola (Berk. &amp; M.A. Curtis) Berl. &amp; De Toni (causing grapevine downy mildew), Venturia inaequalis (Cooke) G.

Autores: Daniel, Claudia; Hommes, Martin; Koller, Martin.
Abstract: 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, use of functional agro-biodiversity, release of biocontrol agents and a few approved pesticides of biological and mineral origin, as well as mating disruption or the use of fine-mesh netting to exclude pests. The methods used in organic production might also be applicable in IPM systems. This paper considers the methods used in organic Brassica vegetable and oilseed rape production, and discusses their potential and limitations in the context of their application in integrated pest and...

Tomaten im Freiland  Die Suche nach Phytophthora-toleranten Sorten für den ökologischen Anbau
Provedor de dados: 21
Autores: Horneburg, Bernd.
Outdoor tomato production in Central Europe is seriously impaired by Phytophthora infestans. The screening of 3500 accessions identified those with favourable agro-nomic, morphological, and phenological attributes and a high field resistance against P. infestans. About 90% of the most interesting varieties are kept in private collections and genebanks. Commercial varieties were of minor importance. The severity of late blight infections did strongly depend on location and year.

The “Rodenator”: an efficient device for controlling field mice and root voles?
Provedor de dados: 21
Autores: Kelderer, M.; Casera, C.
Field mice (Microtus arvalis), wood mice (Apodemus sylvaticus) and root voles (Arvicola  terrestis) constitute a big threat to the organic apple orchards in South Tyrol. The use of  rodenticides on the fields is not allowed in organic farming. The fruit growers rely on the  help of different natural predators. If populations increase, the possibility of trapping and  gasifying with equipment which produces carbon monoxide and carbon dioxide remain.  Both methods are problematic. Trapping requires skill and time. Gasifying is not  unproblematic to the health of the user. Recently a device has been imported which is  used successfully in the United States to control different soil-dwelling rodents. In the  orchards of South Tyrol, various field trials were...

The use of copper seed treatments to control potato late blight in organic farming
Provedor de dados: 21
Autores: Keil, S.; Benker, Dr. M.; Zellner, Dr. M.
In organic farming potato late blight still is an unsolved problem. Up to now copper fungicides are the only way to control this disease. Delaying the start of the epidemic reduces the need for fungicide usage throughout the growing season. In order to postpone the beginning of the blight epidemic as well as the start of spraying primary stem infections shall be reduced by a copper seed treatment. In field trials these treatments not only reduced primary stem infection but also decreased the number of infected daughter tubers.

Etude et suivi des ravageurs des grandes cultures et de la faune utile associée
Provedor de dados: 21
Surveillance: la plupart des ravageurs des grandes cultures ne sont nuisibles que localement et (ou) sporadiquement. Il est toutefois indispensable de suivre leur évolution afin de pouvoir agir rapidement et efficacement en cas de nécessité. L'anticipation des problèmes, la prévision, l'avertissement et le conseil de mesures adéquates permettent d'éviter des pertes économiques aux agriculteurs et des atteintes à l'environnement.  Ravageurs nouveaux : régulièrement des ravageurs d'importance secondaire ou nouveaux provoquent de gros dégâts, généralement suite à l'introduction d'une nouvelle culture, de nouvelles variétés ou de nouvelles pratiques culturales. Lorsque ces cas se présentent, l'étude de la biologie et de la nuisibilité de ces ravageurs ainsi...

Betningsmedlen i stråsäd och deras effekter
Provedor de dados: 21
Bakgrund  Under vårvintern hade vi ett flertal diskussioner med företrädare för olika hushållningssällskap och firmor involverade rörande utsädesbehandling. Resultatet av dessa diskussioner blev att vi under år 2005 fick möjlighet att utföra fältförsök i vårvete och korn på tre olika försöksplatser inom Mellansvenska försökssamarbetets ansvarsområde, nämligen Lanna (R-län), Vreta-Kloster (E-län) och Hedemora (W-län). Samtliga försök utfördes enligt GEP-standard.    Sammanfattning  I flertalet av försöken har behandlingarna medfört merskörd och tydlig sjukdomsbekämpning. Några anmärkningsvärda skillnader mellan preparaten kunde inte fastställas. Tyvärr kunde vi inte testa ThermoSeed mer än i Hedemora-försöken, men dessa försök visade lovande resultat...

Hvorfor bøvler vi med gulrust - og hvordan kan vi undgå det?
Provedor de dados: 21
Autores: Hansen, Jesper.
Gulrust forekommer de fleste år i Danmark, og med års mellemrum opstår der epidemier, som kan mere end halvere kornudbyttet og forringe høstens kvalitet for den enkelte landmand. Alle kan vel huske 2009, hvor næsten al vintertriticale i Danmark blev ødelagt. Problemet er ikke blevet mindre af, at der er opstået såkaldte aggressive racer af rust, som udvikler sig hurtigere og voldsommere, end vi har kendt til tidligere - det gælder også under varme og relativt tørre forhold. Hvordan kan det gå så galt på så kort tid?

Untersuchungen zur Niederschlagsabhängigkeit der  Verbreitung des Ampferblattkäfers (Gastrophysa viridula)
Provedor de dados: 21
Autores: Hann, Dr. Patrick; Kromp, Dr. Bernhard.
The broad-leaved dock (Rumex obtusifolius) is a widely distributed weed of cultivated  grasslands. Since the dock leaf beetle (Gastrophysa viridula) can defoliate docks  extensively, if occurring in sufficient high densities, it is considered to be a potential  part of a biocontrol strategy against R. obtusifolius. Our study aimed at investigating  the influence of precipitation on the distribution of G. viridula. For that, 635  questionnaires were sent out to organic farmers and surveys were conducted on 39  farms in Lower Austria. The results showed G. viridula preferring regions with  sufficient precipitation. These observations confirmed laboratory results reported in  literature and should be considered in a concept for the enhancement of dock beetle...

Proteomic analysis of the Mycocentrospora acerina-carrot interaction during storage
Provedor de dados: 21
Autores: LOUARN, Sébastien; Jensen, Birgit; NAWROCKI, Arkadiusz; NØRREGAARD JENSEN, Ole.
During post harvest storage, a large proportion of carrots (more than 50%) may have to be discarded due to the development of liquorice rot caused by Mycocentrospora acerina. This fungus is soil borne and brought into the store in to soil adhering to the root. Liquorice rot development is mainly related to physiological or structural resistance of carrot, therefore the control of this storage disease is based on cultural practices and storage conditions.  It is believed that carrots at the beginning of storage can resist disease developments due to chemical defence mechanisms involving some proteins, peptides and secondary metabolites. The hypothesis is that proteome changes during storage of carrots are related to the susceptibility to M. acerina. During...

Rooting and vitality of poinsettia cuttings was increased by arbuscular mycorrhiza in the donor plants
Provedor de dados: 21
Autores: Druege, Uwe; Xylaender, Marco; Zerche, Sigfried; von Alten, Henning.
In this paper, we provide evidence that the rooting performance of cuttings can be improved by the arbuscular mycorrhizal (AM) symbiosis of donor plants. Poinsettia stock plants were inoculated with the Glomus intraradices isolate H510 and grown in three different cultivation systems (two organic and one conventional). AM colonization was not related to P availability in the substrate. Decay of the excised cuttings in response to unfavorable postharvest storage conditions was significantly reduced by AM colonization of the stock plants. In most cases, AM significantly promoted the formation of adventitious roots in the stored cuttings. The strongest effect of AM was found when donor plants were grown in a modified organic substrate; then AM-conditioned...

Erfahrungen mit neuen feuerbrandresistenten Unterlagen in Süddeutschland
Provedor de dados: 21
Autores: Ruess, Franz.
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 root-stocks 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 fruit...
