摘　　要：[目的]明确河南省番茄灰霉病菌对苯胺基嘧啶类杀菌剂嘧霉胺的抗药性状况。[方法]采用菌丝生长速率法测定从河南省不同保护地中采集、分离的101株番茄灰霉病菌对嘧霉胺的敏感性。[结果]高抗菌株8株(7.92%),中抗菌株52株(51.49%),低抗菌株22株(21.78%),敏感菌株19株(18.81%)。[结论]河南省番茄灰霉病菌已对嘧霉胺产生不同水平的抗药性,各地应合理更换或轮换使用与嘧霉胺无交互抗性的药剂,以确保番茄灰霉病的有效控制。[Aims] The study aims to clarify the resistance of Botrytis cinerea to pyrimethanil. [Methods] One hundred and one B. cinerea strains were isolated from diseased tomato fruits or leaves, which were collected from different regions of Henan Province, and their resistance to pyrimethanil was evaluated by the method of hypha growth inhibition. [Results] The frequency for high, middle, and low resistance to pyrimethanil were 7.92, 51.49 and 21.78%, respectively. [Conclusions] The B. cinerea from tomato in Henan has already generated different level resistance to pyrimethanil. The management for tomato grey mould disease should replace or rotate using reasonable fungicide without cross-resistance with pyrimethanil.
