| 摘 要： | 在广西鸡骨草种植基地，发现一种发生严重的叶枯病，植株自下部叶片开始枯黄，然后向上蔓延，严重时整株枯死。经田间调查、标本采集、病原菌分离、形态学鉴定及致病性测定，明确该病害由丝核菌属（Rhizoctonia）引起。该病害在田间的发病率为69%～88%，病情指数为17.4～34.6。

| Abstract: | The leaf blight disease of Abrus cantoniensis seriously occurred in fields in Guangxi. The disease symptoms were as followed: the bottom leaves turned yellow and blight at the beginning, and then spread upward, and finally the whole plant became blight and death. Field investigations, sample collection, pathogen isolation, morphological identification and pathogenicity test were conducted. The results showed that the disease was caused by Rhizoctonia. The diseased plant incidence was 69%-88%, and the disease index was 17.4-34.6 in the field. |
