[目的]对银中杨黑星病病原菌进行鉴定。[方法]对黑龙江省哈尔滨市银中杨上一叶部病害发病情况进行了田间调查和采集病害标本,并通过致病性测定、分子和形态学鉴定相结合。[结果]分离得到的菌株为山杨黑星孢菌,为银中杨黑星病病原菌Fusichadium tremulae(Fr.)。[结论]此前尚未见山杨黑星病菌引起银中杨黑星病的报道。
[Objective] The aim of this study was to identify the pathogen of S.c. [Method] Field investigation and disease samples were collected from the disease of the previous leaf of Zhongzhong Yang, Harbin City, Heilongjiang Province. Through the pathogenicity test, molecular and morphological identification were combined. [Result] The isolated strain was Aspergillus aculeatus, which was Fusichadium tremulae (Fr.), A pathogen of P. yunnanensis.
