摘要： 从天津市茄子保护地中分离出122个茄子灰霉病菌株中，多菌灵的抗性菌占41.0%,且多为高抗菌株；多菌灵与乙霉威间表现负交互抗性关系；速克灵和扑海因的抗性菌比率为27.9%,均为低抗水平，EC50为2301120.3810μg/mL,两种药剂存在交互抗性；对多菌灵、速克灵、扑海因均有抗性的菌株占供试菌株的27.9%,均敏感的菌株占59.0%,对多菌灵有抗性而对速克灵和扑海因敏感的菌株只占13.1%。

Abstract: One handred and twenty-two strains of Botrytis cinerea were isolated from greenhouse eggplants in Tianjin The ratio of resistant strains to carbendazim was 41.0%,and most of them were high in resistance The relationship between carbendazim and diethofencarb is negative cross resistant The ratio of the resistant strains to procymidome and iprodione is 27.9%,and all of them are low resistance,its EC50 being between 2.3011-20.3810 μg/mL,and the relationship between procymidome and iprodione being cross resistance The result suggested that there are about 27.9% strains that have resistance to carbendazim,procymidome and iprodione,and 59.0% strains are sensitive to the three fungicides Besides,the strains resistant to carbendazim but sensitive to procymidome and iprodione constitute about 13.1%.
