摘要
为了防治黄瓜白粉病,研究以4%四氟醚唑水乳剂(150g·hm-2、112.5g·hm-2、75g·hm-2)进行田间药效试验,对照药剂为40%氟硅唑乳油(75g·hm-2)。结果表明:4%四氟醚唑水乳剂按150g·hm-2、112.5g·hm-2、75g·hm-2施药后的防效分别为84.59%、76.18%、70.51%,而对照防效为68.27%。因此,4%四氟醚唑水乳剂是防治黄瓜白粉病的理想药剂。
To control cucumber powdery mildew,4% tetraconazole aqueous emulsion (150 g/ha, 112.5 g/ha,75 g/ha)were used in the field efficacy trials,with 40% flusilazole (75g/ha)as control a-gent.The results showed that:the control efficiences of 4% tetraconazole aqueous emulsion at 150 g/ha, 112.5 g/ha and 75 g /ha after spraying were 84.59%,76.18% and 70.51%,respectively.The control effect of 40% flusilazole at 75g/ha was 68.27%.Therefore,4% tetraconazole aqueous emulsion is the best insecticide to control cucumber powdery mildew.
