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2?301120?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％.“,”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 EC 50 being between 2 3011 20 3810 μg/mL,and the relationship between procymidome and iprodione b...
