Ensuring food security requires new green pesticides. Double-stranded RNA (dsRNA) pesticides trigger RNA interference by exogenous dsRNA specifically targeting pests and diseases. They can inhibit the expression of key genes in pathogens or pests, thereby achieving effective control of specific pests and diseases. DsRNA pesticides are environmentally friendly, with strong specificity and efficient gene silencing ability, while they have problems such as high production costs. Using engineering strains to produce dsRNA is a feasible strategy, whereas currently there is no cost-effective engineering strain for producing dsRNA. This article reviews the research progress and production strategies of using microorganisms to produce dsRNA, hoping to provide reference for dsRNA production.
