Bactericidal composition

Abstract

The invention discloses a bactericidal composition. The bactericidal composition comprises an active ingredient A and an active ingredient B, wherein the active ingredient A is benzovindiflupyr, the active ingredient B is selected from one or two of N-(2-(2-chloro-4-trifluoromethylphenoxyl)phenyl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-amide and N-(2-(2,4-dichlorophenoxyl)phenyl)-3-(difluoromethyl)-1-methyl-1H-pyrazole-3-amide, and the weight ratio of the active ingredient A to the active ingredient B is [1:50]-[50:1]. The composition can be formulated into conventional preparations such assuspending agent, aqueous emulsion, suspoemulsion, microcapsule suspending agent, suspension seed coating agent, wettable powder, water dispersible granules, granules, effervescent granules, and dispersible oil suspension. According to verification experiments, the composition has reasonable ratio, higher control effect on most diseases of various crops, remarkable bactericidal effect, wide bactericidal spectrum, and obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a fungicidal composition containing benzovinfluconazole. Background technique [0002] Benzovindiflupyr is a pyrazole amide fungicide, a succinate dehydrogenase inhibitor, broad-spectrum, high-efficiency, and longer-lasting effect. It can widely control foliar diseases and soil pathogens. Important resistance management tool. Benzofluconazole has shown outstanding efficacy against major diseases in many crops such as wheat, corn and specialty crops. The product has a good control effect on wheat leaf blight, peanut black spot, wheat take-all and wheat base rot, especially on wheat powdery mildew, corn small spot and gray mold, and on Asian soybean Rust has excellent control effect. No cross-resistance with methoxyacrylate and triazole fungicides. The structural formula is as follows: [0003] [0004] Fluphenamide is a pyrazole amide compound developed by Central China N...

AI Technical Summary

Problems solved by technology

[0008] Due to the current non-standard use of pesticides, the resistance of diseases to pesticides is getting stronger and stronger, resulting in higher and higher use of pesticides, causing environmental pollution

Through our experimental research, it has been shown that the compounding of benzovinfluconazole, flufenazole amide and chlorophenyl ether amide has obvious synergistic effect within a certain range, and can well overcome the shortcomings of existing products. Improve the efficacy and reduce the dosage, and there are no relevant reports at home and abroad
