[目的]为高粱链格叶斑病的防治提供依据。[方法]对高粱叶片上的一种叶斑病进行了病原菌的分离与鉴定。[结果]病原菌在PDA平板上生产迅速，菌丝边缘白色，中央灰绿色；分生孢子串联成链状，褐色，近圆柱状或倒棍棒状，有横隔膜2~7个，纵隔膜0~4个，鉴定其为链格孢属（Alternaria）真菌。[结论]该病在高粱叶片上发病严重，应对其侵染治病过程以及致病机制进行进一步研究。

we aimed to provide a basis for the prevention of Alternaria leaf spot in sorghum. [Method] One kind of pathogen of leaf spot in sorghum was isolated and identified. [Result] The pathogen grew quickly on PDA plates. The aeri-al hyphae of the pathogen had white edge and green-grey center. The conidia were brown and connected into a chain. The shape of conidia was nearly cylindrical or inverted clavate. The conidia had 2-7 diaphragms and 0-4 longitudinal septa. lt was identified as Alternaria fungus. [Conclusion] The leaves of sorghum were sus-ceptible to leaf spot. So the infection and healing process and pathogenic mecha-nism of leaf spot were needed to study further.
