摘　　要：为明确10%甲维盐·氟铃脲水分散粒剂对甘蓝甜菜夜蛾的防效,以1%甲维盐乳油和5%氟铃脲乳油为对照药剂,开展了田间药效试验。结果表明,10%甲维盐·氟铃脲水分散粒剂150~450 g/hm^(2)防治甘蓝甜菜夜蛾速效性较好且药效稳定,药后7 d防效达81.9%~90.5%,且均无药害现象发生。其中,10%甲维盐·氟铃脲水分散粒剂450 g/hm^(2)田间防效极显著高于对照药剂1%甲维盐乳油、5%氟铃脲乳油。综合考虑生产成本等因素,生产中10%甲维盐·氟铃脲水分散粒剂防治甘蓝甜菜夜蛾建议药剂用量为300~450 g/hm^(2),施药次数为1次。In order to clarify the control efficacy of 10%emamectin benzoate·hexaflumuron WDG against Spodoptera exigua in cabbage,a field efficacy trial was carried out by using 1%emamectin benzoate EC and 5%hexaflumuron EC as the control agents.The results showed that 10%emamectin benzoate·hexaflumuron WDG 150-450 g/hm^(2) had good rapid and stable efficacy against S.exigua in cabbage,the control efficacy was ranged from 81.9%to 90.5%on the 7th day after treatment,and no phytotoxicity occurred.Among them,the field efficacy of 10%emamectin benzoate·hexaflumuron WDG 450 g/hm^(2) was significantly higher than that of the control agents(1%emamectin benzoate EC and 5%hexaflumuron EC).Considering the production cost and other factors,the recommended dosage of 10%emamectin benzoate·hexaflumuron WDG for controlling S.exigua in cabbage in production is 300-450 g/hm^(2),with one application frequency.
