摘　　要：采用菌丝生长速率法测定了苹果轮纹病菌对多菌灵的敏感性。结果表明：多数苹果轮纹病菌菌株对多菌灵表现敏感，建立了以敏感性苹果轮纹病菌菌株的EC50平均值（0．2582±0．1208）mg／L为准的敏感性基线；11．11％的菌株已产生2～4倍的低水平抗药性，抗药性菌株主要分布于山东西部区域。Sensitivity of Botryosphaeria dothidea to carbendazim Was determined by measuring mycelial growth in fungi- cide-amended media. Most of isolates presented sensitivity to carbendazirn, The mean EC50 of（0. 2582 ± 0. 1208）mg/L for sensitive isolates was made as sensitivity baseline. 11 low-resistance isolates to carbendazim were found in 99 isolates collected from 2007 to 2008 in Shandong province, which resistance index was 2 -4 times and mainly distributed throughout the western area of the province.
