烟草黑胫病研究进展

Research Progress on Tobacco Black Shank Disease

烟草黑胫病是烟草上一种常见的真菌性病害。该病常与烟草青枯病混合发生,引起烟株萎蔫性死亡,导致产质量严重下降。近几年该病在贵州黔西南烟区发生普遍,损失严重,对烤烟的可持续发展产生了巨大的威胁。该文从烟草黑胫病的发病特点出发,综述该病侵染循环、发病条件、致病机理及防治对策,以为更好地防治该病奠定一定的理论基础。

Tobacco black shank disease was a common fungal disease in tobacco.The disease usually occured mixing with tobacco bacterial wilt disease,causing wilting death and a serious decline in yield and quality of tobacco.In recent years,the disease has wide spreaded in the tobacco- growing areas of southwestern of Guizhou,has caused serious losses, and threatened for the sustainable development of flue-cured tobacco production hugely.This article departured from the tobacco black shank disease＇s characteristics,overviewed infection cycle of the disease,the incidence of conditions,pathogenesis and prevention measures,in order to lay a theoretical foundation in better fight against the disease aspect.
