5种杀菌剂对黄瓜灰霉病菌的室内毒力测定

摘要

The indoor toxicities of 5 fungicides against Botrytis cinerea were detected by the method of mycelium growth inhibition .The results showed that 25%dimethomorph WP had the best control effect , fol-lowed by 50%boscalid WG and 50%procymidone WP .The control effects of 400 g/L pyrimethanil SC and 500 g/L iprodione SC were relatively low .%采用菌丝生长抑制法测定了啶菌恶唑、啶酰菌胺等5种杀菌剂对黄瓜灰霉病菌（ Botrytis cinerea）的室内毒力。结果表明，25％啶菌恶唑乳油防治效果最好，其次为50％啶酰菌胺水分散粒剂和50％腐霉利可湿性粉剂，400 g/L嘧霉胺悬浮剂和500 g/L异菌脲悬浮剂防效较低。
