灰葡萄孢是从康涅狄格州的六个温室中感染的植物中分离出来的。45个菌株进行了体外评价，以确定杀菌剂敏感性苯并咪唑（苯菌灵和甲基托布津）和二甲酰亚胺杀菌剂（乙烯唑啉和异菌脲）。B。从每个温室取样回收具有杀真菌剂抗性的灰霉病菌分离物。苯并咪唑耐药比二甲酰亚胺耐药更常见（分别为74 - 76%和36 - 43%）。多种杀菌剂抗性是常见的。19株耐苯并咪唑和二甲酰亚胺杀菌剂。对二甲酰亚胺类的抗性水平（EC 50）低于对苯并咪唑类的抗性水平。菌株生长速率与杀菌剂敏感性或EC 50无关。杀菌剂耐药性显然是无关的模式，在温室采样的杀菌剂使用。
Botrytis cinerea was isolated from infected plants in six greenhouses in Connecticut. Forty-five isolates were evaluated in vitro to determine fungicide sensitivity to benzimidazole (benomyl and thiophanate-methyl) and dicarboximide fungicides (vinclozolin and iprodione). B. cinerea isolates with fungicide resistance were recovered from each greenhouse sampled. Benzimidazole resistance was more common than dicarboximide resistance (74 to 76% versus 36 to 43%, respectively). Multiple fungicide resistance was common. Nineteen isolates were resistant to both a benzimidazole and a dicarboximide fungicide. The level (EC50) of resistance to dicarboximides was low compared with resistance to benzimidazoles. Isolate growth rate was not correlated to fungicide sensitivity or EC50. Fungicide resistance was apparently unrelated to the patterns of fungicide use in greenhouses sampled.
