由Alternaria solani(Ell.et MaMart.)Sorauer引起的番茄早疫病是上海郊区番茄生产上的主要病害之一。它为害番茄的叶、茎、果实,致使产量下降,品质变劣。我们于1983年对番茄早疫病的病原菌形态、特性及寄主范围进行了测定,并对照比较了Joly(《Ly genereAlternaria》,1964)及魏景超(《真菌鉴定手册》,1977)等对该种特性与特征的描述,在上海郊区引起番茄早疫病菌实属Alternaria solani.(Ell.et.Mart)Sorauer。鉴定结果综述如下。一、发病部位与症状番茄从苗期至成熟采收期
Early blight of tomato caused by Alternaria solani (Ell.et MaMart.) Sorauer is one of the major diseases in tomato production in the suburbs of Shanghai. It is harmful to tomato leaves, stems, fruits, resulting in decreased yield, quality deterioration. We tested the pathogen morphology, characteristics and host range of tomato early blight in 1983 and compared the characteristics and host range of Joly (“Ly genereAlternaria”, 1964) and Wei Jingchao (“Fungal Identification Handbook”, 1977) Characterization of the species causing Alternaria solani in the suburbs of Shanghai is indeed Alternaria solani. (Ell. Et. Mart) Sorauer. The results of the review are summarized below. First, the incidence of parts and symptoms of tomato from the seedling to mature harvested
