Bactericidal composition containing fluopyram and famoxadone

Abstract

The invention relates to a composite bactericide with effective components of fluopyram and famoxadone. The mass ratio of fluopyram to famoxadone is 1 to 80:80 to 1, a total content of fluopyram and famoxadone in the composite preparation is 1% to 80%. With methods widely-known by technicists of the field, the composite bactericide can be prepared into forms of suspending agents, wettable powder, water dispersible granules, aqueous emulsion, or micro-emulsion. The bactericidal composition provided by the present invention can be used for controlling various diseases of vegetables and fruit trees, especially cucumber downy mildew, powdery mildew, pumpkin powdery mildew, grape and tomato downy mildew, tomato late blight, capsicum epidemic disease, and the like.

Description

Technical field: [0001] The invention relates to a compound fungicide with synergistic effect in the field of pesticides, the effective components of which are fluopyram and oxazolidone. Background technique: [0002] Downy mildew and blight caused by the invasion of Oomycetes are frequently-occurring diseases of vegetables and other crops (grapes, strawberries, potatoes, etc.). It often causes a significant reduction in crop yields or even a loss of production. This year, with the increase of the planting area of ​​fruit trees and vegetables in my country, especially the large-scale promotion of the cultivation technology of vegetables in protected areas, the incidence and degree of crop diseases have increased significantly. The frequent occurrence of diseases makes the use of fungicides continue to increase, and high-density spraying makes the bacteria more and more resistant to drugs, thus creating a vicious circle. Traditional fungicides such as carbendazim, ethylphosp...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to solve the shortcomings of fluopyram pesticide and oxafefenone pesticide for the control effect of the above crop diseases, such as single effect and short duration, and provide a kind of effective synergistic effect, long duration, effective A new pesticide composition that prevents oomycete diseases of various crops and delays the emergence of resistance - a fungicidal composition with a reasonable mixture of fluopyram and oxafefenone as active ingredients
