Pesticide bactericidal composition, water dispersible granule and preparation method and use thereof

Abstract

The present application discloses a pesticide bactericidal composition, a water dispersible granule and a preparation method and a use thereof, and relates to the field of pesticides. The active ingredients of the pesticide bactericidal composition comprise chlorothalonil, tebuconazole and picoxystrobin with a weight ratio of (10-50):(1-2):1, optionally (10-20):(1-6):(1-3), optionally (10-20):(1-2):1 or 10:6:3. The ternary compounded composition of the present application has a synergistic effect in the aspect of preventing and controlling plant diseases, and can achieve above 90% of prevention and control effect of grape downy mildew and wheat powdery mildew. The ratios of the composition in the present application can allow pesticides to better exert a synergistic effect, thereby reducing the usage amount of the pesticides and improving the efficacy.
