摘　　要：用75%苯醚甲环唑·咪鲜胺锰盐WP进行山核桃枝枯病的田间药效试验。结果表明,在山核桃枝枯病初发期,用75%苯醚甲环唑·咪鲜胺锰盐WP推荐剂量有效成分500~750 mg/kg处理,施药后45 d防效为75.0%~79.5%,并对山核桃和其他非靶标生物安全。75%苯醚甲环唑·咪鲜胺锰盐WP可以用于防治和控制山核桃枝枯病。The field trial of difeno-conazole-prochloraz 75% WP against Melanconium oblongum Berk on cathayensis Sarg. was conducted. The results showed that in the early period of M.oblongum, the control rate of difeno-conazole-prochloraz 75% WP against M.oblongum on C. cathayensis could reach 75.0 %-79.5 % . 45 days after application when used at the dose of 500-750 mg/kg, and difenoconazole-prochloraz 75% WP was safety to C.cathayensis and other non-target organisms.
