摘　　要：[目的]明确番茄灰霉病菌对咯菌腈的敏感性及其与其他杀菌剂之间是否存在交互抗性。[方法]采用菌丝生长速率法测定灰霉病菌对咯菌腈、多菌灵、乙霉威、腐霉利、嘧霉胺和啶酰菌胺的敏感性。[结果]咯菌腈对106株野生菌株EC50的平均值为(0.0135±0.0096)mg/L。咯菌腈与其他5种杀菌剂之间均不存在交互抗性。[结论]野生菌株对咯菌腈的敏感性的平均值,可作为番茄灰霉病菌对咯菌腈的敏感基线。咯菌腈可广泛用于番茄灰霉病的防治。[Aims] The study aims to explicit the sensitivity of Botrya＇s cinerea to fludioxonil and to make sure that if there is cross-resistance or not between fludioxonil and other botryticides. [Methods] The sensitivity of isolates of Bottytis cinerea to fludioxonil, carbendazim, diethofencarb, procymidone, pyrimethanil and boscalid were tested by measuring mycelial growth rate. [Results] The main of EC50 values for 106 wild-isolates was （0.013 5± 0.009 6） mg/L. There is no positively-correlated cross-resistance between fludioxonil with other five fungicides. [Conclusions] The data （0.013 5 ± 0.009 6） mg/L could be used as baseline-sensitivity ofB. cinerea to fludioxonil. The results indicate that fludioxonil could be widely used to control gray mold.
