烟草黑胫病的研究进展

Progress of Research on Tobacco Black Shank

黑胫病是烟草上的一种主要病害,由细菌引起。近几年在遵义地区发病严重并与青枯病混发,导致烟叶产量大幅下降,质量降低。因此,加强烤烟黑胫病综合防治,对烤烟的可持续发展至关重要。该文介绍了烟草黑胫病的病害症状、病原菌、侵染循环、发病条件、发病机制,烟草黑胫病化学防治的历史、现状及存在的问题,重点介绍了目前研制的新型杀菌剂,提出加强对农药的抗性风险评估、加强新型药剂和混剂的研发与推广应用、科学合理用药等策略,以控制烟草黑胫病的发生和发展。

Tobacco black shank is one of the main plant diseases which is caused by bacteria.Tobacco black shank recent years it is serious and always incidence with solanacearum.All of these lead to a significant decline and lower quality on tobacco.So Strengthen comprehensive methods to prevention and control the tobacco black shank is essential for sustainable development of flue-cured tobacco.In this article,there was a exhaustive introduce on the tobacco black shank symptoms,pathogen,infection cycle,incidence of conditions,the pathogenesis and the chemical prevention and control history,current situation and problems on tobacco black shank.the article also focus on the developed fungicides recently,and list a forward view on strengthen the risk assessment on pesticide resistance,strengthen the new mixture of pharmacy and promote the use of,strategy on use the fungicide scenically and rationally.All of these was in order to control the occurrence and development of the tobacco disease and provided a reference on the study of tobacco black shank.
