摘　　要：为了解湖北省小麦主产区的小麦赤霉病菌对多菌灵和咪鲜胺的抗药性,对2014年分离获得的350株禾谷镰刀菌进行多菌灵和咪鲜胺的敏感性测定。结果表明:湖北省小麦赤霉病菌未出现对多菌灵和咪鲜胺的抗性菌株,多菌灵用于防治小麦赤霉病仍具有一定使用价值。咪鲜胺防治效果明显优于多菌灵,以咪鲜胺与多菌灵按1∶7比例复配后的防治效果最优。Sensitivity of 350 F.graminearumstrains,isolated in 2014,to carbendazim and prochloraz was detected to explore the drug resistance of F.graminearumto carbendazim and prochloraz in the main producing areas in Hubei.Results：All the isolates were sensitive to carbendazim and prochloraz.The fungicide of carbendazim could be continually applied in wheat production in controlling Fusarium head blight in the future in Hubei Province.The control efficacy of prochloraz was better than that of prochloraz,and their mixtures at the ratio of 1∶7was of the greatest control efficacy.
