Description

technical field

[0001] The invention belongs to the technical field of biological control of plant diseases, and in particular relates to a fungus of the genus Trichospora ( Seimatosporium sp.) M7SB 41 and its application. Background technique

[0002] Tobacco powdery mildew (Tobacco Powdery Mildew) is one of the main diseases of tobacco leaf production, which is caused by powdery mildew ( Erysiphe cichoracearum DC.) fungal disease caused by infection, which occurs nationwide. The lesion usually starts from the lower leaves and spreads from bottom to top. In severe cases, all the leaves fall off, leaving only the veins (Guo Qitang et al., 2009). The diseased leaves are brown in color after baking, with obvious punctate lesions on the leaf surface, thin as paper, less oil, severe lack of aroma, heavy miscellaneous gas, large damage, high crushing rate, which seriously affects the yield and quality of tobacco leaves ( Liu Caiyun et al., 2018). At present, cultivating dis...
