烟草青枯病是由青枯雷尔菌(Ralstonia solanacearum)引起的以土壤传播为主的细菌性病害,是烟草生产上的主要病害之一。生物防治是解决烟草细菌性青枯病的一条理想途径。大量试验研究结果表明,用生物手段防治烟草青枯病在室内表现为良好的防治效果,但由于生防因子易受到环境因素的影响,在大田上的防治还不够稳定,防效不太理想。笔者综述了国内外研究学者利用诱导剂、生防菌、转基因植物及其他生物资料防治烟草青枯病的研究进展,并提出在今后的工作中应建立以烤烟水旱轮作为主的轮作制度和采用无公害的植物抗逆诱导剂来提高植物对青枯病的抗病性。
Tobacco bacterial wilt is a soil-borne bacterial disease caused by Ralstonia solanacearum, which is one of the major diseases in tobacco production. Biological control is an ideal solution to tobacco bacterial wilt. A large number of experimental studies have shown that biological control of tobacco bacterial wilt in the indoor performance of a good control effect, but because of biological factors susceptible to environmental factors, prevention and control in the field is not stable enough, the control effect is not ideal. The author summarizes the research progress on tobacco bacterial wilt by using domestic and foreign research scholars using inducing agents, biocontrol agents, transgenic plants and other biological materials, and puts forward that in the future work should be established to establish a rotation system with flue-cured tobacco and dry wheatear as the mainstay The use of pollution-free plant anti-retrograde inducer to improve the plant’s resistance to bacterial wilt disease.
