Abstract: Microbial pesticides are an important way to promote the green control of crop pests and diseases, and also an effective way to ensure increase production and reduction loss of grain crops. Based on the application acreage of microbial pesticides on grain crops, this paper reviewed the achievements of microbial pesticide application since 2018 in view of crops types and application regions. This paper also discussed and sorted out the existing problems with microbial pesticide application, and proposed the corresponding promotion ideas. The review serves to provide reference for the development of microbiological pesticide.
