摘　　要：为明确苹果斑点落叶病菌的抗药性现状,采用组织分离法从罹病苹果叶片分离出病原菌,并测定了其对四种杀菌剂的敏感性。结果表明:苹果斑点落叶病菌对扑海因、速克灵和乙磷铝相对较敏感,其平均EC50值分别为0 2885μg·mL-1、1 2483μg·mL-1和5 9912μg·mL-1;而对代森锰锌相对不敏感,平均EC50达40 4997μg·mL-1。To investigate the fungicide-resistance of Alternaria mali Roberts, the pathogen from apple leaves were isolated and their sensitivities to four fungicides were surveyed . The results showed that they were relatively sensitive to iprodione, procymidone and fosetyl-Al with an EC_(50) value of 0.2885,1.2483 and 5.9912 g mL(-1 )separately. They were relatively less sensitive to mancozeb with an EC_(50) value of 40.4997 g· mL(-1).
