摘 要：
葡萄座腔菌Botryosphaeria dothidea、棒状拟盘多毛孢Pestalotiopsis clavispora、乌饭树拟茎点霉Phomopsis vaccinii、尖孢炭疽菌Colletorichum acutatum、胶孢炭疽菌 Colletotrichum gloeosporioides 5种病原菌是目前引起山东青岛胶南地区蓝莓枝枯病的主要病原菌。本试验采用菌丝生长速率法测定6种杀菌剂的毒力。结果表明，吡唑嘧菌酯、咯菌腈、苯甲>丙环唑对5种病原菌抑制作用较强，EC50值介于0.0035～2.2245 mg>L-1之间，对由该5种病原菌引起的蓝莓枝枯病防效很好。

Abstract Botryosphaeria dothidea， Pestalotiopsis clavispora， Phomopsis vaccinii， Colletorichum acutatum， Colletotrichum gloeosporioides were 5 main pathogens of blueberry twig dieback in Qingdao Jiaonan area of Shandong Province. The indoor toxicities of 6 fungicides against 5 pathogens were detected by mycelium growth rate method. The results showed that pyraclostrobin，fludioxonil，difenoconazole-propiconazole had relatively strong inhibition rate. The EC50 were between 0.0035～2.2245 mg>L-1. The control effects were excellent.
