Abstract

The invention belongs to the technical field of pesticides, and discloses cyflufenamid water-dispersible granules, which comprise, by mass, 10-80% of cyflufenamid, 3-12% of a wetting agent, 3-12% of adispersing agent, 0-10% of a disintegrant, 0.1-3% of a binder, and 5-84% of a filler. The preparation method comprises: mixing the components according to a certain ratio, uniformly stirring, crushing to obtain mother powder, uniformly mixing the mother powder and a binder, granulating, drying, and screening to obtain the cyflufenamid water-dispersible granules. According to the present invention, the obtained cyflufenamid water-dispersible granules can overcome the disadvantages of the suspending agent and the wettable powder, can reduce the pollution to the environment, and is mainly used for the prevention and control of cucumber powdery mildew, wheat powdery mildew, apple powdery mildew and grape powdery mildew.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and in particular relates to a water-dispersible granule of cycloflufenamide. Background technique: [0002] Fenoxanil is an amide fungicide jointly developed by BASF and Nippon Pesticides. [0003] Cyflufenamide has good systemic and residual activity and is an inhibitor of melanin biosynthesis. It is used to prevent and control cucumber powdery mildew, wheat powdery mildew, apple powdery mildew and grape powdery mildew, and is safe for crops, mammals and the environment. [0004] At present, the dosage form of cycloflufenamide in the market is suspension concentrate. Although the suspension concentrate is an environmentally friendly preparation, its storage stability is an important performance index. It is related to the performance and application effect of the product, and factors that affect stability More, the requirements for the concentration of the original drug, additives, and pH...
