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...

Higher antioxidant and lower cadmium concentrations and lower incidence of pesticide residues in organically grown crops: a systematic literature review and meta-analyses Organic Eprints
Baranski, Marcin; Srednicka-Tober, Dominika; Volakakis, Nikolaos; Seal, Chris; Sanderson, Roy; Stewart, Gavin B.; Benbrook, Charles; Biavati, Bruno; Markellou, Emilia; Giotis, Charilaos; Gromadzka-Ostrowska, Joanna; Rembiałkowska, Eva; Skwarło-Sonta, Krystyna; Tahvonen, Raija; Janovska, Dagmar; Niggli, Urs; Nicot, Philippe; Leifert, Carlo.
Demand for organic foods is partially driven by consumers' perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. Most importantly, the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods, with those of phenolic acids, flavanones, stilbenes, flavones, flavonols...

Reducing copper use in the environment: the use of larixol and larixyl acetate to treat downymildew caused by Plasmopara viticola in viticulture Organic Eprints
Thuerig, Barbara; James, Emily E.; Schärer, Hans-Jakob; Langat, Moses K.; Mulholland, Dulcie A.; Treutwein, Jonas; Kleeberg, Ina; Ludwig, Mathias; Jayarajah, Praveen; Giovannini, Oscar; Markellou, Emilia; Tamm, Lucius.
BACKGROUND: Plant extracts might provide sustainable alternatives to copper fungicides, which are still widely used despite their unfavourable ecotoxicological profile. Larch bark extract and its constituents, larixyl acetate and larixol, have been shown to be effective against grapevine downy mildew (Plasmopara viticola) under semi-controlled conditions. The aim of this study was to reduce the gap between innovation and the registration of amarketable product, namely to develop scalable extraction processes and to evaluate and optimise the performance of larch extracts under different conditions. RESULTS: Toxicologically and technically acceptable solvents like ethanol were used to extract the active compounds larixyl acetate and larixol from bark in...
