Abstract

The invention relates to a germicidal composition in the field of pesticide complex formulation; the active components are cyflufenamid and a part of imidazole germicides, and the active components are blended binarily; the weight ratio of the two active components is 80:1-1:90, and the preferable weight ratio is 50:3-5:65; the total weight percent of the active components in the germicidal composition is 1%-90%, and preferably 8%-75%; the residues are auxiliary components which are allowable and acceptable in pesticides; the composition can be prepared into wettable powder, suspensions, soluble liquid, emulsions in water, water dispersible granules and granules by known methods; the germicidal composition of the invention is mainly used to control fungal diseases of crops such as grains, cotton, oil, fruit, vegetables, and flowers.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to a bactericidal compound containing cycloflufen and some imidazole compounds Cyazofamid, prochloraz, imidazosin and rice blastate as active ingredients. combination. 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 addition, this agent will not affect the environment and b...
