%T Integration of different control measures to maximise disease control of Plasmopara viticola in Italian organic viticulture
%U http://orgprints.org/7508/
%X 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.
