摘要
为明确不同剂量杀菌剂添加3%卵磷脂·维生素E后对黄瓜白粉病的防治效果,采用茎叶喷雾法进行田间药效试验。结果表明:与单独施用杀菌剂250 g/L吡唑醚菌酯乳油或12%苯醚甲环唑·氟唑菌酰胺悬浮剂相比,在杀菌剂中添加助剂3%卵磷脂·维生素E 5000倍液可提高杀菌剂对黄瓜白粉病的防治效果,提高黄瓜产量;在防治黄瓜白粉病效果相当的情况下,加入助剂3%卵磷脂·维生素E,可使杀菌剂减量20%。
In order to determine the control effect of different doses of fungicides added with 3%lecithin·vitamin E on cucumber powdery mildew,a field trial was assayed by spray method.The results showed that,compared with the single application of 250 g/L pyraclostrobin EC or 12%difenoconazole·fluzobactam SC,adding 3%lecithin·vitamin E 5000 times solution to these fungicides could improve the control effect of fungicides on cucumber powdery mildew and increase the yield of cucumber.In the case that the control effect of cucumber powdery mildew was equivalent,adding 3%lecithin·vitamin E as the assistant could reduce the amount of fungicide by 20%.
