摘要
引起马铃薯晚疫病的致病疫霉(Phytophthora infestans)是马铃薯生产中最具破坏性的病原体之一。生防菌剂(biocontrol agents,BCAs)代替化学杀菌剂防治马铃薯晚疫病是保障马铃薯生产可持续发展的重要措施之一。文章简述了马铃薯晚疫病研究概况和特点,总结了当前生防菌防治马铃薯晚疫病研究的文献。从细菌、真菌和放线菌3个层次系统归纳了致病疫霉生防菌的菌株种属、菌株来源、防治效果、抑菌活性物质及作用机制。分析了生防菌剂在研发和推广应用中面临的挑战性和局限性。提出了未来马铃薯晚疫病生物防治应从增强马铃薯自身防御功能、建立晚疫病预测模型、关注生防菌种群动态和揭示致病疫霉防治机制4个方面进行深入研究。旨在为马铃薯晚疫病生防菌剂的研发和推广应用,及马铃薯绿色产业可持续发展提供参考。
Phytophthora infestans,which causes potato late blight,is one of the most destructive pathogens in potato production.Biocontrol agent(BCAs) as an alternative to chemical fungicides to control potato late blight is one of the important measures to ensure the sustainable development of potato production.In this paper,the research situation and characteristics of potato late blight were briefly reviewed,and the current researches of biocontrol microbes against potato late blight were summarized.The species,source,control effect,antibacterial active substances and action mechanism of the biocontrol microbes for P.infestans were systematically summarized from three levels of bacteria,fungi and actinomycetes.The challenges and limitations of the development and application of biocontrol agents were analyzed.It was suggested that the future biological control of potato late blight should be further studied in four aspects:strengthening the defense function of potato,establishing the prediction model of late blight,paying attention to the population dynamics of biocontrol microorganisms and revealing the control mechanism of P.infestans.The aim is to provide reference for the development and application of biocontrol agents against potato late blight,and sustainable development of potato green industry.
