烟草白粉病研究进展

Research Progress on Tobacco Powdery Mildew

烟草白粉病是由专性寄生菌引起的烟草重要病害之一,主要危害烟草叶片,导致烟叶受损,严重时造成整株死亡,使烟草的产量和品质下降。烟草白粉病是严重制约烟草绿色高质量发展的重要原因之一。本文阐述了烟草白粉病的病原菌形态特征,总结了其发病原因及发生特征,综述了农业防治、化学防治、生物防治等烟草白粉病防治措施,并从抗病基因筛选、植物代谢产物开发、混合使用各类物质等方面提出了展望,以期为烟草白粉病的绿色防控提供参考。

Tobacco powdery mildew is one of the important tobacco diseases caused by specific parasitic fungi,which mainly harms tobacco leaves,damage tobacco leaves,and in severe cases,causes whole plant death,and lead to a decrease in tobacco yield and quality.Tobacco powdery mildew is one of the important reasons that seriously restricts the green and high-quality development of tobacco.This paper elaborated on the morphological characteristics of the pathogenic fungi of tobacco powdery mildew,summarized its causes and characteristics,summarized agricultural control,chemical control,biological control and other prevention and control measures for tobacco powdery mildew,and put forward prospects from the aspects of disease resistant genes screening,development of plant metabolites,and mixed use of various substances,in order to provide references for the green prevention and control of tobacco powdery mildew.
