在对温室栽培番茄植株上白粉病发生的全年调查中，病害在6月和7月最严重。所有番茄植株（45个商品品种和11个育种系）都感染了病原菌，但感病程度不同。病原菌为附生性，主要在番茄植株叶片上产生白色圆形脓疱。病原菌在分生孢子梗上产生单个分生孢子，在接种的番茄叶片上产生分叉附着胞，可能是Anoidiumsp.的白粉菌属。
During a year-round survey on the occurrence of powdery mildew on greenhouse-cultivated tomato plants, the disease was most severe in June and July. All tomato plants (45 commercial cultivars and 11 breeding lines) tested were infected with the pathogen but had different degrees of susceptibility. The pathogen was epiphytic and produced white, round pustules mainly on leaves of tomato plants. The pathogen produced conidia singly on conidiophores and forked appressoria on inoculated tomato leaves and seemed to be anOidiumsp. ofErysiphe polygonitype.
