对昆明西芹主产区滇池沿岸西芹病毒病的发生进行调查和病样采集,经电子显微镜检测和血清学试验,结果表明,西芹病毒病的严重发生流行是由多种植物病毒复合侵染所致,影响发病的因素主要有气温、生育期和传毒介体昆虫。提出以选用无病毒种子、杜绝毒源传播为主,药剂防治为辅的综合防治技术。 The occurrence of celery virus in Dianchi Lake, the main producing area of ​​Kunming celery, was investigated and the samples were collected. The results of electron microscopy and serological tests showed that the serious occurrence of celery virus was caused by the combination of various plant viruses Dyed, the main factors that affect the incidence of temperature, growth period and poison mediator insects. Proposed to use virus-free seeds, to eliminate drug-based transmission, supplemented by chemical prevention and control of integrated control technology.
