为明确湖南省草莓灰霉病菌菌株的抗药性状况,2013-2015年从湖南省不同地区草莓灰霉病病果或病叶上经单孢分离获得草莓灰霉病菌454株,采用最小抑制浓度法(MIC)检测不同地区草莓灰霉病菌株对多菌灵、腐霉利、异菌脲、嘧霉胺的抗药性。结果表明:草莓灰霉病菌对多菌灵、腐霉利、异菌脲、嘧霉胺的抗性频率分别为55.73%,77.31%、3.52%和77.31%;所测菌株对4种杀菌剂的敏感性类型有Cbz~RPcm~RIpd~RPmt~R、Cbz~SPcm~RIpd~RPmt~R、Cbz~RPcm~RIpd~SPmt~R、Cbz~SPcm~RIpd~SPmt~S、Cbz~RPcm~SIpd~SPmt~R、Cbz~SPcm~RIpd~SPmt~R等6种,其所占比例分别为33.26%、5.07%、41.41%、4.63%、3.96%、11.67%,未发现对4种...

To investigate the resistance of Botrytis cinerea to carbendazim, procymidone, iprodione and pyrimethanil, 454 strains of B.cinerea were collected from the diseased strawberry fruits or leaves in different regions of Hunan Province in 2013-2015 and resistance to the four fungicides were detected by minimal inhibitory concentration (MIC) method. The results showed that the resistance frequency of carbendazim, procymidone iprodione and pyrimethanil was 55.73%,77.31%, 3.52% and 77.31%, respectively. The susceptibility types were Cbz~RPcm~RIpd~RPmt~R, Cbz~SPcm~RIpd~RPmt~R, Cbz~RPcm~RIpd~SPmt~R, Cb...
