The efficacy of different spraying programs against two fungal pathogens in organic grape production
Journal of Plant Diseases and Protection 117 (5), 220-225
Abstract: Regarding the continual increase of organic grape production in Europe, seven different spraying programs were formed and tested in Slovenian vineyards against grape powdery mildew (Uncinula necator) and grape downy mildew (Plasmopara viticola) in 2007 and 2008. An Eco spraying program (Myco-Sin + Basfoliar Aktiv + Champ formula 2 FLO + Kumulus DF + potassium waterglass + Fennel extract) showed the highest (87%) efficacy against grape powdery mildew on grape bunches in 2007, while almost total efficacy in controlling grape downy mildew on leaves was established in 2008 with the same program and with a Basfoliar Aktiv + potassium waterglass + Fennel extract spraying program. Satisfactory efficacy (> 83%) in controlling grape downy mildew on grape bunches in 2008 was achieved with the following programs: Eco, Basfoliar Aktiv + potassium waterglass + Fennel extract, and Champ formula 2 FLO + Vitisan + Fennel extract. In the control treatment the infection was high in both years, what made the tested programs highly applicable.
