针对烟草青枯病的低毒药剂噻菌铜研究进展

Review on Low Toxic Pesticide Thiodiazole-copper on Ralstonia Wilt of Tobacco

青枯病是一种严重的危害烟草的细菌性根茎类病害,目前,化学防治依旧是该病害的主要防控方式。综述近几年关于噻菌铜杀菌作用机制、其他农作物细菌性病害应用情况、特殊施用方法和农药的独特优点等几个方面的最新研究进展,发现噻菌铜是一种噻唑类有机铜杀细菌农药品种,2个化学基团具有双重抑制效果,在多种农作物细菌病害的防治上都取得了较好的效果。根据青枯病的发病特点,建议使用灌根的方式施用噻菌铜。此外,噻菌铜还具有环境安全性高、与生物防治菌剂协同效果好的两大独特优点。综上所述,低毒药剂噻菌铜是一种可以在烟草病虫害绿色防控的生产实践中推广应用的药剂。

Ralstonia wilt is a serious tobacco root disease caused by bacteria,and chemical control is currently the major management strategy.This review summarized recent research on mode of action,application cases,implementation method and special advantages of thiodiazole copper.Thiodiazole copper is a bactericide with two inhibitive chemical components,with obvious effect on control bacterial diseases in many crops.Based on disease pattern of Ralstonia wilt,root drench is the suggested implementation method.In addition,thiodiazole copper has the advantage of high environmental safety and synergetic effect with biological control agents.In conclusion,low toxic bactericide thiodiazole copper is able to be applied in the integrated pest management of tobacco.
