Alternatives to copper-based treatments for the control of grapevine downy mildew (Plasmopara viticola): 5-year synthesis of trials in France and Italy Organic Eprints
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)...

Are there alternatives to copper for controlling grapevine downy mildew in organic viticulture? Organic Eprints
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...

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...

Integration of different control measures to maximise disease control of Plasmopara viticola in Italian organic viticulture Organic Eprints
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.
