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４１０％，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２７９％，均为低抗水平，ＥＣ５０为２３０１１２０３８１０μｇ／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２７９％，均敏感的菌株占５９０％，对多菌灵有抗性而对速克灵和扑海因敏感的菌株只占１３１％。
Among the 122 strains of Botrytis cinerea isolated from the eggplant protection area in Tianjin, the carbendazim resistant bacteria accounted for 410%, mostly high antibacterial strains; the carbendazim and diethylcarbamate showed negative cross-resistance Sexual relations; the rate of resistant gram bacteria and metsulfuron-resistant bacteria was 27 9%, were low anti-level, EC50 2 301120 3810 μg / mL, there is interaction between the two agents; on carbendazim, The strains resistant to both kelp and puerarin accounted for 279% of the tested strains, and all the strains were sensitive to 590%. They were resistant to carbendazim and were sensitive to cloketine and puerarin Of the strains accounted for only 13 1%.
