烟草白粉病的研究进展

摘要：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，近年来部分地区发病严重，是严重制约烟草绿色高质量发展的重要原因之一。为了了解烟草白粉病的发病全过程，本文对烟草白粉病的病原菌形态特征、发病原因、发病特征以及选用抗病品种、加强农业防治、生物防治、药剂防治措施等研究进行综述，并从抗病基因筛选、植物代谢产物开发、混合使用等提出防控建议，为烟草白粉病的绿色防控提供参考。

Research progress on tobacco powdery mildew

Abstract: Abstract: Tobacco powdery mildew is one of the important tobacco diseases caused by obligate parasitic bacteria. It mainly harms tobacco leaves, leading to leaf damage and even the death of the whole plant. It reduces the yield and quality of tobacco. In recent years, the disease has been serious in some areas, which is one of the important reasons that seriously restrict the high-quality development of tobacco green. In order to understand the whole process of tobacco powdery mildew, this paper reviews the morphological characteristics, pathogenic causes, pathogenic characteristics of tobacco powdery mildew, and the selection of disease-resistant varieties, strengthening agricultural prevention and control, biological prevention and control, pharmaceutical prevention and control measures.
