35%苯甲·咪鲜胺水乳剂防治黄瓜靶斑病田间药效试验

Field Efficacy of 35% Difenoconazole & Prochloraz EW in Controlling Corynespora cassiicola

采用5种杀菌剂对露地黄瓜靶斑病进行药剂筛选试验。结果表明：35％苯甲．咪鲜胺防效最好，为78．81％～82．21％，25％咪鲜胺和70％基硫菌灵次之，分别为78．56％,～82．07％、76．61％～81．61％，三者之间无极显著差异，此3种药剂的防效较好，可以在生产上推广应用：而10％苯醚甲环唑防效最差，为59．45％～62．49％，与前3种药剂有极显著差异。

The medicament-sifting experiment on five fungicides in controlling Corynespora cassiicola of outdoor cucumbers was conducted. The results showed that 35% Difenoconazole ＆ Prochloraz EW had the best effects and the control efficiency was 78.81%～82.21%, and 25% Prochloraz ME and 70% Thiophanatemethyl WP came second, with their control efficiency of 78.56%～82.07% and 76.61%～81.61%, respectively. These three fungicides didn＇t have the most significant difference and all had better control efficacy. So they could be popularized and applied to the crop production. But 10% Difenoconazole was the worst, with the control efficiency of 59.45%～62.49%, having the most significant difference compared with the first three fungicides.
