柑橘溃疡病生防微生物研究进展

Research Progress of Biocontrol Microorganisms of Citrus Canker

柑橘溃疡病是柑橘生产中重要的病害之一,对全球柑橘产业发展具有巨大破坏作用。微生物防治在柑橘溃疡病害防治中具有独特的优势,不仅可以减轻病害发生,且对环境安全、无污染。本文通过对近20年来有关微生物防治柑橘溃疡病的研究报道进行分析,发现柑橘溃疡病的微生物防治目前仍主要集中在生防菌的室内筛选与鉴定,其中以细菌中芽孢杆菌类单菌防效研究较多,施用方式主要以活菌株或菌剂为主,具体机制的研究还比较缺乏,抑菌活性物质分离鉴定也鲜有报道。生防真菌和噬菌体的开发具有较大潜力。柑橘溃疡病生防菌的资源开发、作用机制以及田间应用均有待深入研究。

Citrus canker disease is one of the important diseases in citrus production.Microbial control has unique advantages in the prevention and control of citrus canker disease,which can not only reduce the occurrence of the disease,but also be safe and pollution-free to the environment.Based on the analysis of the literatures about microbiological control on this disease in the past 20 years,it was found that its microbial prevention still mainly focused on the screening and identification of biocontrol bacteria in the laboratory,in which the species from bacillus and the control effect of single bacterium had been mostly reported.The main application methods were live strains or bacterial agents.While the study of the mechanism and identification of antibacterial active substances are rarely reported.There is still great potential for the development of biocontrol fungi and phages.In a word,resources,action mechanism and field application of biocontrol microorganisms for the control of citrus canker disease need to be further studied.
