"十四五"期间我国微生物农药研究与应用新进展OA

Microbial pesticides are biopesticides that use living microorganisms as active ingredients,mainly including fungi,bacteria,viruses,protozoa,and genetically modified microorganisms.They constitute an important component of green prevention and control strategies for plant pests and diseases.Based on an analysis of newly registered microbial pesticide products in China during the 14th Five-Year Plan period,this review summarizes the major advances achieved by the project team"Exploration,Improvement and Development of Biocontrol Microbial Resources for Crop Pests and Diseases".The review focuses on the genetic improvement of biocontrol microbial strains and the development of new products;the research,development and application of Spodoptera frugiperda nucleopolyhedrovirus-based insecticides;the exploration of biocontrol microbial resources for plant-parasitic nematodes and the development of new products;the exploration of rare biocontrol microbial resources and elucidation of their biocontrol mechanisms against major agricultural diseases;and the development of green and efficient production technologies for biocontrol microorganisms and novel microbial pesticides.It also summarizes the major crop pests and diseases and the damage they cause,the diversity and mechanisms of biocontrol microorganisms,and the characteristics of registered microbial pesticide products.In addition,research progress in other countries is reviewed,existing challenges are analyzed,and corresponding countermeasures and future perspectives are proposed.
