摘要:

植物病害的发生对作物经济效益构成了严重威胁,而化学农药的滥用则进一步加剧了对环境及人类健康的风险,因此,植物病害的生物防治策略被视为未来病害控制的主要趋势。当前,芽胞杆菌类生防微生物资源在植物病害防治中得到广泛应用,该类细菌通过多种机制发挥防病作用,包括靶向病原物进行竞争作用和分泌抑菌活性物质,直接抑制病原物的生长;靶向植物,通过根际定殖并形成生物膜、诱导植物系统抗性以及促生作用来提升植物的抗病性;同时,它们还能改善根际土壤环境,刺激土著有益微生物类群共同发挥作用,为植物健康生长创造有利条件。本文综述了芽胞杆菌类生防细菌在防治植物病害的作用机理及其作为生防菌剂的应用现状,并探讨了其在现代农业中的应用前景和面临的挑战,以期为后续此类生防微生物农药产品研发提供有价值的参考依据。

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.
