经过室内毒力测定，９种杀菌剂中的双灵、速克灵和扑海因对Ｂ．ｃｉｎｅｒｅａ的毒力最高，ＥＣ５０依次为０．８２μｇ／ｍＬ、０．８６μｇ／ｍＬ和１．１０μｇ／ｍＬ。多菌灵对该菌的毒力最差，ＥＣ５０高达４７８．８５μｇ／ｍＬ。田间药效试验结果表明，速克灵对黄瓜灰霉病防治效果最好，相对防治效果为９０．８８％；其次为双灵和扑海因，防效分别为８６．３６％和８０．９４％。另外，ＢＣ１和ＢＣ２二个菌株在含有多菌灵为１０００μｇ／ｍＬ的培养基上仍能生长，并难以测到ＭＩＣ值，说明二个菌株已对多菌灵都产生了抗药性，而对速克灵和甲基托布津尚未产生抗药性，即无明显的负交互抗性和交互抗性。对多菌灵的抗性菌株经过多次无药培养后，其抗药性未见丧失，具有较强的抗性持久性
After indoor toxicity determination, 9 kinds of fungicides in the Shuangling, klinker and puerarin on the B. The cinerea had the highest virulence with EC50 of 0.82 μg / mL, 0.86 μg / mL and 1.10 μg / mL, respectively. Carbendazim has the poorest virulence to EC50 up to 478.85μg / mL. The field efficacy test showed that Sukuling had the best control effect on Botrytis cinerea, the relative control effect was 90.88%, followed by Shuangling and Luopin, the control effects were 86.36% and 80.94 %. In addition, BC1 and BC2 two strains in the carbendazim 1000μg / mL medium still grow, and difficult to measure the MIC value, indicating that the two strains have carbendazim have been resistant to, and the speed Kline and methyl thiophanate have not yet developed drug resistance, that is, no significant negative cross-resistance and cross-resistance. Carbendazim resistant strains after several drug-free culture, the resistance has not been lost, with strong resistance to persistent
