摘要
从分离和征集的土壤真菌中筛选出13个对黄萎病菌有生防潜力的菌株。温室盆栽试验表明,这13个菌株均可有效地降低棉黄萎病的发生率和病情指数,其中以菌株T3 4(Trichodermasp.)、THT(T.hamatum)和T2 4(T.sp.)作用效果最为明显。田间小区防效试验表明,3个木霉菌株对棉黄萎病第一次发病高峰和第二次发病高峰的防治效果达到38.2%～53.5%和13.6%～36.0%。
From some soilborne fungal isolates isolated or collected, 13 potential biocontrol agents for Verticillium dahliae were screened. The results of greenhouse experiments indicated that 13 potential agents lowered the disease incidence and index of Verticillium wilt. Among them, T34 (Trichoderma sp.), THT (T. hamatum) and T24 (T. sp.) showed to be the most effective antagonists against Verticillium dahliae. The control effects in the field trails were 38.2%～53.5%, and 13.6%～36.0%, respectively during the first and second summit of Verticillium wilt disease.
