Abstract: Pests, diseases and weeds are detrimental to grain production; and the overuse of chemical pesticides has led to increasingly serious problems such as pesticide residues and environmental pollution. As one of the main types of biological pesticides, microbial pesticides have been developing rapidly in recent years due to their low residues and low toxicity to humans and animals. This paper summarizes the progress of microbial pesticides, fungicides and herbicides in the screening of biocontrol strains, product creation and application in our country, additionally, suggestions and prospects are made for the development of microbial pesticides which aims to provide reference for industry-related units and practitioners.
