Chinese. 摘 要：2009年2--3月对广西香蕉主产区真菌性叶斑病病原进行抽样鉴定。结果显示，广西香蕉真菌性叶斑病病原至少有10种，主要病原为Cordanamusae，分布广，检出率为56．77％～92．19％；Corynespora cassiicola和Deightoniella torulosa为次，两种病原菌均主要集中在南宁地区，检出率分别为32．34％和22．61％；叶斑病类型以单一病原侵染为主，检出率为78．13-92．19％；复合侵染的叶斑病类型以2种病原共同侵染居多。

The results showed that at least 10 fungal pathogens were found in the banana leaf spot samples. Cordana musae was the most frequently observed fungal pathogen with a detection rate of 56.77%--92.19% in the samples. Corynespora cassiicola and Deightoniella torulosa were mainly observed in the samples collected from the plantations at Nanning City, with the detection rates of 32.34% and 22.61%, respectively. The banana leaf spots with only a single pathogen were predominant （78.13 %- 92.19 % ） compared to those with two or more fungal pathogens.
