Abstract

The invention relates to a sterilizing composition containing Cyflufenamid, which is obtained by the binary compounding of the effective ingredients, namely Cyflufenamid and dithiocarbamate compounds, wherein the weight percentage ratio of the two effective ingredients is (90-1): (1-90), preferably (50-3): (10-90); and the total percentage by weight of the total effective ingredient in the sterilizing composition is 1-90%, preferably 10-80%, and the balance is the auxiliary element which is permitted to be used and can be accepted in the pesticide. The known method can be used for preparing the sterilizing composition into wettable powder, suspending agent, powder, microemulsion, emulsion in water and water dispersible granules. Cyflufenamid and dithiocarbamate compounds serve as effective ingredients to prevent and control bacterial diseases and fungoid diseases on various plants, such as vegetables, fruit trees, grains, ornamental plants and the like.

Description

technical field [0001] The present invention relates to the technical field of pesticide compounding, in particular to a method of using any one of the compounds of cycloflufen and thiocarbamate compounds Zineb, Bineb, Mancozeb, Mancozeb, and Thiamazine as A bactericidal composition with two-component compound of active ingredients. Background technique [0002] Cyflufenamide is a fungicide with a new parent structure developed by Nippon Soda Corporation. Its chemical structural formula is as follows: [0003] [0004] It has excellent effects and characteristics on various vegetables and wheat powdery mildew and peach ash, and has the same activity on benzimidazole, imidazole, methoxyacrylate resistant bacteria and sensitive bacteria. Cyflufenamide has extremely low toxicity to humans and animals, and has no impact on the next generation. The teratogenicity and mutagenicity tests are all negative, and there is no irritation or allergy to eyes and skin in production. In...
