AI Technical Summary

Technical Problem

Existing fungicides have a single site of action, which leads to the development of drug resistance in pathogens and a decrease in efficacy with long-term use. At the same time, the amount of pesticides used increases, causing serious environmental pollution problems. Furthermore, the success rate of combining fungicides is low.

Method used

A bactericidal composition is formed by combining pyrimidine-containing substituted pyrazole compounds with various bactericides. The weight ratio of active components A and B is 1:99-99:1. In the composition, active component A is a pyrimidine-containing substituted pyrazole compound or its salt, and component B is selected from bactericides such as respiratory inhibitors. The composition enhances the effect through different mechanisms of action.

Benefits of technology

It improves the bactericidal effect, reduces the amount of pesticides used, delays the development of drug resistance in pathogens, and reduces environmental pollution.
