摘要
2002—2005年，于不同季节，到云南省灯盏花主要栽培区对灯盏花黄萎病发病情况、病原和发病因子进行系统调查。结果表明，在主要栽培区灯盏花黄萎病的发病率为10％～15％，严重时超过20％，该病由黑白轮枝菌（Verticillium albo-atrum）所致。灌水不当或阴雨连绵的天气，是引起灯盏花黄萎病大面积发生危害的直接因子。
Investigation on Verticilliurn wilt of Erigeron breviscapus, including the pathogens, factors and inci dences were conducted in main planting areas in different seasons from 2002 to 2005. The results showed Verticillium albo-atrurn was the pathogen of E. breviscapus wilt. The incidence of the wilt was 10%-15%, sometimes ex ceeding 20%. Improper irrigation or rainy seasons were direct reasons causing the wilt to occur on a large scale.
