摘要：

采用菌丝生长速率法对两个来自海南的木薯炭疽菌株进行了13种杀菌剂的室内筛选。结果表明，必扑尔（25 %丙环唑EC）、咪鲜胺（25 %咪鲜胺EC）和国光多菌灵（50 %多菌灵WP）的EC50值最小，抑菌效果最好；敌克松（55 %敌磺钠WP）和代森锰锌（50 %代森锰锌WP）的EC50值最大，抑菌效果最差，建议生产上使用丙环唑、咪鲜胺和多菌灵等来防治木薯炭疽病。

Abstract:

Based on two Colletotrichum gloeosporioides isolates came from HaiNan province, 13 fungicides were screened in laboratory by hypha growth rate method. Propiconazol 25 % EC, prochloraz 25 % EC and carbendazim 50 % WP were found to have the lowest EC50 value and good inhibition of Colletotrichum gloeosporioides isolates, whereas fenaminosulf 55 % WP and mancozeb 50 % WP had the highest EC50 value but poor inhibition, propiconazol, prochloraz and carbendazim were suggested to be used for field control of Cassava Anthracnose.
