Research and Development Progress and Application Challenges of Bacterial Biocontrol Agents

Abstract

In recent years, there has been a notable increase in global interest in bacterial biocontrol agents as a pivotal approach to the management and control of agricultural pests and diseases. This paper reviews the progress in research and development of bacterial biocontrol agents, including the screening and identification of efficient biocontrol strains, the study of biocontrol bacterial metabolites, and the application of genetic engineering and synthetic biology. The challenges faced in its practical application are analysed, including environmental stability, production cost, regulatory approval, farmers' awareness and resistance management. Finally, the future development direction of bacterial biocontrol agents is discussed, with the aim of providing a reference for research and application in this field.
