CO-FREE Alternative Test Products for Copper Reduction in Agriculture Organic Eprints
Schmitt, Annegret; Scherf, Andrea; Mazzotta, S; Kühne, Stefan; Pertot, Ilaria; Köhl, Jürgen; Markellou, Emilia; Andrivon, Didier; Pellé, R; Bousseau, M; Chauvin, J-E; Thiéry, D; Delière, Laurent; Kowalska, Jolanta; Parveaud, Claude-Eric; Petit, Audrey; Giovinazzo, Robert; Brenner, Johanna; Kelderer, Markus; Lammerts van Bueren, E.T.; Bruns, Christian; Finckh, Maria R.; Kleinhenz, Benno; Smith, Jo; Simon-Levert, A; Pujos, P.; Trapman, Marc; Stark, J; van Cutsem, P; Neerakkal, S; Kleeberg, Hubertus; Peters, Arne; Tamm, Lucius.
The project CO-FREE (2012-2016) aimed to develop strategies to replace/reduce copper use in organic, integrated and conventional farming. CO-FREE alternative test products (CTPs) were tested and integrated together with decision support systems, disease-tolerant varieties, and innovative breeding goals (ideotypes) into improved management strategies. CO-FREE focused on apple/apple scab (Venturia inaequalis), grape/downy mildew (Plasmopara viticola), and tomato and potato/late blight (Phytophthora infestans). Starting point of the project were ten CTPs with direct or indirect modes of action including Trichoderma atroviride SC1 and protein extract SCNB, Lysobacter spp., yeast-based derivatives, Cladosporium cladosporioides H39, the oligosaccharidic complex...

Efficacy of microbiological treatments and trap crop against pests of winter oilseed rape Organic Eprints
Kowalska, Jolanta; Remlein-Starosta, Dorota.
Winter oilseed rape was cultivated in monoculture or in combination with turnip rape as trap crop sown in trap strip. Preventative microbiological treatments for diseases control in winter oilseed rape were tested using Trichoderma asperellum and product based on effective microorganisms. Microorganisms were effective to protect of oilseed rape and allowed to obtain higher yield comparing to untreated plants. No effect of turnip rape as trap crop stripe on infestation by insect pest was observed. There was no statistically significant influence of presence B. rapa on total yield. Statistically higher percentage of infected pods collected from area with turnip rape compared to monoculture area was noted.

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

Organic Knowledge Network Arable - D.3.1 State-of-the-art research results and best practices Organic Eprints
Niggli, Urs; Schmidt, Jennifer; Watson, Christine; Kriipsalu, Mait; Shanskiy, Merrit; Barberi, Paolo; Kowalska, Jolanta; Schmitt, Annegret; Daniel, Claudia; Wenthe, Ulla; Conder, Malgorzarta; Wohlfahrt, Jens; Schild, Marion; Dierauer, Hansueli; Krauss, Maike; Moeskops, Bram; Padel, Susanne; Micheloni, Cristina; Constanzo, Ambrogio; Thonar, Cécile; Wilbois, Klaus-Peter.
In this deliverable of the Project OK-Net Arable project, the findings from peer-review research on the productivity of organic arable crops are reported. Then the conclusions and recommendations for five most important levers which can be used by the farmers are presented. Finally, the most important recommendations of the EIP-AGRI Focus Group on Organic Farming - Optimizing Arable Yields are summarized in order to put innovation on organic farms in its social context.
