Composition containing pydiflumetofen and copper gluconate as well as preparation and application thereof

Abstract

The invention provides a composition containing pydiflumetofen and copper gluconate. The composition comprises pydiflumetofen and copper gluconate in a mass ratio of (1: 20)-(30: 1). The invention belongs to the technical field of pesticides, and unexpectedly finds out that compounding of pydiflumetofen and copper gluconate according to a certain weight ratio can generate a synergistic bactericidal effect, is safe and efficient, effectively reduces the use amount of pesticide preparations, reduces the cost, and improves the pesticide effect through a large number of indoor bioassays and field efficacy tests. The pesticide resistance of diseases can be delayed, the pesticide cost can be reduced, and the pollution to the environment can be alleviated.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a composition containing flufenapyramide and copper gluconate, as well as its preparation and application. Background technique [0002] Flufenapyramide, its chemical name is 3-(difluoromethyl)-N-methoxyl-methyl-N-[(RS)-1-methyl-2-(2,4,6- Trichlorophenyl)ethyl]pyrazole-4-carboxamide, a succinate dehydrogenase inhibitor developed by Syngenta Crop Protection Co., Ltd., Switzerland, its mechanism of action is by interfering with the respiratory electron transport chain complex The tricarboxylic acid cycle on II inhibits the function of mitochondria, prevents them from producing energy, inhibits the growth of pathogenic bacteria, and eventually leads to their death. Flufenapyramide has the advantages of novel structure, high activity and wide bactericidal spectrum, etc. It has high control effects on wheat head blight, cucumber powdery mildew, tomato bacterial wilt, b...

Problems solved by technology

[0004] The long-term use of a single fungicide increases the resistance, increases the dosage, and aggravates the environmental pollution

The compounding of pesticide varieties with different action mechanisms is expected to overcome the defects of single use of pesticides. It is a common method to prevent and control the resistance of pathogens, but reasonable
