| Abstract: | Objective] 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. It 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. |
