摘　　要：[Objective] This study aimed to avoid and delay the generation of resis- tance in Botrytis cinerea to boscalid. [Method] The sensitivity of Botrytis cinerea to boscalid was tested by the mycelial growth rate method. The distribution of sensitivity variation of B. cinerea to boscalid in different regions was cleared, and the sen- sitivity baseline of B. cinerea from Liaoning Province to boscalid was established. [Result] The ECso values of B. cinerea strains from Liaoning Province ranged from 0.080 0 to 7.787 2μg/ml, and the highest ECho value was 97.34 times higher than the minimum. The average EC50 value （1.973μg/ml） of the 158 strains was treated as the baseline sensitivity of B. cinerea from Liaoning Province to boscalid. [Conclu- sion] It is essential to conduct a risk assessment of drug resistance in B. cinerea to boscalid.[目的]避免和延缓番茄灰霉病菌对啶酰菌胺抗药性的产生。[方法]采用菌丝生长速率法测定辽宁省番茄灰霉病菌对啶酰菌胺的敏感性。明确不同地区番茄灰霉病菌对啶酰菌胺敏感性差异的分布。[结果]辽宁省不同番茄灰霉病菌菌株的EC。值分布在0．0800～7．7872μg，ml，敏感性最低和最高的菌株EC50值相差97．34倍。将符合正太分布的158株番茄灰霉病菌的平均EC50值1．9731μg／ml初步定为辽宁省番茄灰霉病菌对啶酰菌胺的敏感基线。【结论】开展番茄灰霉病菌对啶酰菌胺抗药性风险评估很重要。
