烟草青枯病是由青枯雷尔氏菌（Ralstoniasolanacearum）引起的一种世界范围的病害，以土壤传播为主，防治难，严重影响烟草的产量与品质。青枯病防治有大量的研究，主要以化学防治为主，但仍然存在很多问题。对青枯病生物防治的生防菌研究、无致病力产细菌素菌株研究、诱导抗性研究、转基因植物研究4个方面的研究进展进行综述，为烟草青枯病生物防治提供指导，同时也指出烟草青枯病的生物防治不能仅靠某一生防因子，需要生防菌、抗性诱导剂、转基因植株等多方面综合运用，才能达到经济、有效、持续地控制烟草青枯病。%Tobacco bacterial wilt was caused by Ralstonia solanacearum. It was a worldwide disease and difficult to control. Tobacco bacterial wilt mainly spread through soil and effected on to-bacco yield and quality seriously. There were a lot of researches on bacterial wilt control, but there were still many prob-lems, biological control of tobacco bac-terial wilt was a hopeful approach. Four aspects of biological control of plant bacterial wilt research were reviewed in this paper to provide guidance, including bio-control strains, avirulent bacteriocin producing strains, induced resistance and transgenic plants. Biological control of tobacco bacterial wilt need compre-hensive prevention but not only rely on a biological control factor.
