Bactericidal composition containing pydiflumetofen and preparation and application thereof

Abstract

The invention provides a bactericidal composition containing pydiflumetofen. The bactericidal composition comprises pydiflumetofen and a ginkgo leaf extract in a mass ratio of (1:30)-(60:1). The invention belongs to the technical field of pesticides, and the bactericidal composition provided by the invention is prepared by compounding the pydiflumetofen and the ginkgo leaf extract according to a certain weight ratio, can generate synergistic interaction, is safe and efficient, effectively reduces the use amount of pesticide preparations, can delay the generation of drug resistance of diseases, and is beneficial to reducing the pesticide cost and alleviating the pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicidal composition containing flufenapyramide and its 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, banana leaf spot, banana scab, etc....

AI Technical Summary

Problems solved by technology

[0004] In recent years, the overall resistance of plant pathogens has increased, and the difficulty of prevention and control has become more and more difficult. Vegetables are planted without rest, and there is no crop rotation. The incidence and number of diseases are increasing year by year, and the difficulty of control is also increasing. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous chemical selection. discount

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 and scientific compounding of pesticides can produce synergistic effects, and unreasonable compounding of pesticides may lead to antagonism Therefore, there are often high uncertainties in the effect of pesticide compounding

[0005] At present, there is no report on the compounding of flufenapyramide and ginkgo biloba extract for the control of agricultural diseases
