10-year interdisciplinary monitoring of organic stocklass, vegetable rotations at Warwick-HRI, Kirton, South Lincolnshire, UK Organic Eprints
Schmutz, U; Rayns, F; Sumpton, P.
Interdisciplinary monitoring of an organic stockless farming system has been carried out over ten years on a fertile silty clay loam in the main vegetable production area of the UK. The results draw together economic outcomes with agronomy, soil science and agro-ecology. Organic management has been used at the Kirton research site since conversion of a 3.2 ha unit in 1997. There is great variability in crop yields and marketing results but overall a successful ongoing vegetable production system has been established. Soil fertility, weeds, pests and diseases have been managed successfully without imports of animal manures or green waste compost. Production costs are well controlled and marketable yields are good. However, because the site is a research...

A comparison between organic and integrated apple production: First results after 5 years of observation Organic Eprints
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...

A cseresznyelégy elleni védekezés lehetősége Beauveria bassiana hatóanyagú készítménnyel Organic Eprints
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...

A ‘during-infection’ spray strategy using sulphur compounds, copper, silicon and a new formulation of potassium bicarbonate for primary scab control in organic apple production. Organic Eprints
Jamar, Laurent; Lefrancq, Bruno; Fassotte, Christianne; Lateur, Marc.
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....

A guide to organic grassland Organic Eprints
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.

A new integrative assessment indicator for damage caused by major pests and diseases in the vineyard Organic Eprints
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...

A new system for evaluating inputs for organic farming Organic Eprints
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.

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

A primary survey of aphid species on almond and peach, and natural enemies of Brachycaudus amygdalinus in As-Sweida, Southern Syria Organic Eprints
Almatni, W.; Khalil, N..
Syria is one of the biggest almond producer country in the world. Few arthropdes that live on almond are consider as pests. Aphids are one of the major pests their. In order to change the product to organic we should know more about the pests and their natural enemies in order to use better bio- and organic decisions. A field survey was done to aphids that attack Almond and Peach in Al-Arab mountain at As- Sweida governorate, between 2002 and 2006. Three species of aphids were considered as important pests on both trees. They are Brachycaudus amygdalinus and Brachycaudus helichrysi, which are aphids that feed on the young leaves causing stunted growth; and Pterochloroides persicae which is a species that attack the bark and excretes large...

A simulation program for the timing of fungicides to control Sooty Blotch in organic apple growing. First results in 2003 Organic Eprints
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.

A survey of natural parasitism of mirid bugs by parasitoids on apples and pears in Norway Organic Eprints
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.

Abschätzung des Rückstandsverhaltens von NeemAzal-T/S aus Analysen der Leitsubstanz Azadirachtin A Organic Eprints
Ruch, Beate; Kleeberg, Hubertus.
Bisherige Untersuchungen zeigen, dass Halbwertszeiten von Azadirachtin A auf Blättern bzw. Ernteprodukten in der Größenordnung von einem bis drei Tagen liegen. Unter Berücksichtigung der Ausgangskonzentrationen von Azadirachtin A auf/in den Pflanzen und den untoxischen Eigenschaften des Pflanzenschutzmittles NeemAzal-T/S sowie seines Wirkstoffes NeemAzal sollten Wartezeiten etwa 10 Tage betragen, um Rückstände unterhalb der analytischen Bestimmungsgrenze und unter den nach der Diätverordnung zulässigen Höchstmengen zu erwarten. Das hier dargestellte grobe Konzept enthält Vereinfachungen, die jedoch im Allgemeinen die Rückstandsbelastung überschätzen sollten. Bis zur Festlegung von Höchstmengen und Wartezeiten könnte das vorgestellte Verfahren eine...

Abundanz von Getreideaphiden im Winterweizen in Abhängigkeit von Bewirtschaftunggssystemen mit unterschiedlicher Stickstoff-Intensität Organic Eprints
Lohaus, Katharina; Vidal, Stefan.
The reorganisation from conventional to organic farming practice on a farm located in Northern Germany was accompanied in a long term monitoring to survey the abun-dances of cereal aphids and their natural enemies in winter wheat. The research project focuses on the interactions of host plant and aphids in ecological crop rotation systems differing in their amount of legumes (nitrogen intensive, nitrogen extensive system). Additionally manure treated winter wheat plots established in both ecological crop rota-tion systems were investigated. For comparison the abundance of aphids in conventional farming systems with winter wheat fields nearby were also monitored. The results indi-cate that within the triannual investigation period, aphids significantly...

Abwehr von Wühlmausschäden im ökologischen Obstbau Organic Eprints
Walther, B.; Pelz, H.-J..
Wühlmausschäden sind weit verbreitet und gehören zu den nur schwer lösbaren Pflanzenschutzproblemen im ökologischen Landbau. Nach einer Umfrage des Institutes für Nematologie und Wirbeltierkunde der Biologischen Bundesanstalt für Land- und Forstwirtschaft (BBA), im Jahre 2002 waren 90 % der befragten Obstbaubetriebe von Wühlmausschäden betroffen. Als Hauptschadensverursacher treten vor allem die Schermaus (Arvicola terrestris ), auch große Wühlmaus genannt, und die Feldmaus ( Microtus arvalis) auf. Mit den wenigen zur Verfügung stehenden Mitteln erreicht aber nur ein Bruchteil der ökologisch wirtschaftenden Betriebe einen akzeptablen Bekämpfungserfolg. Von Wissenschaft und Industrie werden viele Anstrengungen unternommen, um bekannte Abwehrmaßnahmen zu...
