Anthracnose is a disease caused by species. They are well known as major plant pathogens, and a black stem disease, specifically caused by and primarily infecting sword bean (), was observed in the Yunnan province, China. To aid disease management and to determine pathogenic characteristics, the species causing the leaf spot disease of hairy vetch was verified as . A sequence analysis of the ITS, ACT, GAPDH, and HIS3 genes was conducted, as well as morphological and cultural characteristics, to identify this species, which has curved conidia. isolates from sword bean formed a distinctive group among species, including those that infect other forage and field crops. Artificially inoculated sword bean seedlings showed typical symptoms of anthracnose, which were similar to field observations. To the best of our knowledge, this is the first report of causing black stem disease on sword beans in China.
炭疽病是由多种物种引起的一种病害。它们作为主要的植物病原体而广为人知，在中国云南省观察到一种 specifically 引起的、主要感染刀豆（）的黑茎病。为了辅助病害管理并确定致病特性，引起毛苕子叶斑病的物种被鉴定为。对 ITS、ACT、GAPDH 和 HIS3 基因进行了序列分析，并结合形态学和培养特征，以鉴定这种具有弯曲分生孢子的物种。从刀豆分离出的 isolates 在包括感染其他饲料和大田作物的物种中形成了一个独特的群体。人工接种的刀豆幼苗表现出典型的炭疽病症状，这与田间观察结果相似。据我们所知，这是中国首次报道引起刀豆黑茎病。
