摘　　要：叶斑病是砂仁生长过程中的重要病害之一,主要为害叶片,给砂仁生产上造成重大的经济损失。为明确砂仁叶斑病病原菌的分类地位,对该病原菌进行分离培养,并通过致病性测定、病原菌形态特征观察及ITS rDNA序列分析对病原菌进行鉴定,将该病原菌鉴定为茄腐镰孢菌(Fusarium solani)。Leaf spot is one of the common disease on Amonum villosum. It usually damages the leaves and reduces the quality and yield of Amomum villosum. In this study, the leaf spot pathogen was isolated and cultivated. Its pathogenicity was also tested. Base on its morpholog- ical characteristics and 1TS DNA sequences analysis, this pathogen was identified as Fusadum solani.
