Biovi : a research program for reducing chemical input in vine and wine

Decrease of chemical inputs during vine management and winemaking is of great importance from a political and societal point of view. In our ongoing project we propose alternative tools to chemicals in the vineyard and the cellar. We have compared a conventional vineyard protection strategy to an alternative strategy using copper and biocontrol products (Biocontrol) against downy and powdery mildews. Both strategies were compared regarding sanitary quality, berries and/or must enological parameters, and physical, biochemical and biological characteristics (berry surface observation, proteomic, metabolomic, volatilomic, metagenomic analyses). Musts obtained with both strategies were then use…
