Abstract

The invention discloses a sterilization composition containing fluopicolide and metalaxyl and application thereof. The sterilization composition contains the fluopicolide, the metalaxyl and pesticide preparation auxiliary components, wherein the weight part ratio of the fluopicolide to the metalaxyl is 5:1-1:15; and the formulation of the sterilization composition is one of oil suspending agent, wettable powder, water dispersible granules, effervescent tablets and aqueous suspending agent. The sterilization composition is used for preventing and controlling cucumber downy mildew. The sterilization composition has obvious synergy on prevention and control effects compared with a single agent, reduces the consumption of pesticides, reduces the application cost, prolongs the service life of preparations, and reduces the adverse effect of the pesticides on the ecological environment.

Description

technical field [0001] The bactericidal composition of the present invention uses fluopicolide and metalaxyl as active ingredients, and is used for preventing and treating crop diseases in agriculture, especially for preventing and treating cucumber downy mildew. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases, especially fungal diseases, which are of many types and cause serious damage. For a long time, chemical control has been the main effective means of disease control. However, due to the long-term single drug use and unscientific drug use, many pathogenic bacteria have developed resistance to the currently used pesticides, and the dosage and frequency of drug use are increasing year by year. It is still difficult to effectively control the development of diseases. At the same time, the harm of pesticides to the ecological environment is also increasing. Increases thereupon, and it is difficult to guaran...
