Sterilization composite containing js399-19 and pyrazole indanyl formamide

The invention relates to the field of bactericides and particularly discloses a sterilization composite taking js399-19 and pyrazole indanyl formamide as active ingredients, wherein the weight ratio of js399-19 to pyrazole indanyl formamide is 1:8-8:1, and the preferable composition ratio is 1:4-4:1. The sterilization composite can be used for preventing wheat scab, cotton wilt disease, rice bakanae disease and banana vascular wilt and the like. The two pesticides are matched to be used, the pesticide effect is enhanced, the pesticide use amount is reduced, rise of pesticide resistance caused by use of a single pesticide is delayed, and the sterilization composite is favorable for reducing environmental pollution and protecting ecological environment.
