芽胞杆菌防治植物病害作用机制与应用
Mechanisms and Applications of Bacillus in Controlling Plant Diseases
摘要
Abstract
Plant diseases cause a serious threat to the economic benefits of crops,while the overuse of chemical pesticides exacerbates the risks to the environment and human health.Therefore,biological control strategies for plant diseases are considered the main trend for disease management in future.At present,Bacillus microbial biocontrol agents have been extensively utilized in plant disease management.These bacteria exert their disease control effects through multiple mechanisms,including targeting pathogens for competitive action and secreting antimicrobial substances to directly inhibit the growth of pathogens;targeting plants for colonizing the rhizosphere and form biofilms,inducing systemic resistance of plant,and promoting plant growth to enhance plant resistance to disease.Concurrently,they can also improve the soil environment of rhizosphere,creating favorable conditions for the healthy growth of plants.This article reviews the mechanisms of action of Bacillus strains in controlling plant diseases and their application status as microbial biocontrol agents and discusses its application prospects and challenges in modern agriculture,aiming to provide valuable reference for the development of subsequent biopesticide products based on these biocontrol microorganisms.关键词
