[目的]测定和评价20%虫酰肼悬浮剂对甜菜夜蛾的防治效果和安全性,为其推广使用提供技术支持。[方法]采用叶面喷雾法施药并测定不同用量的20%虫酰肼SC和25g/L溴氰菊酯EC防治甜菜夜蛾的效果。[结果]20%虫酰肼悬浮剂对甜菜夜蛾有较好的控制效果,药后3和7d,20%虫酰肼各处理防治效果分别达81%和84%以上,高于25g/L溴氰菊酯EC处理的防治效果。[结论]20%虫酰肼SC用于防治甜菜夜蛾,效果好,持效期为7d以上,并且对环境污染少,对甘蓝安全,是防治蔬菜甜菜夜蛾的理想药剂。

[Objective] The aim was to determine and evaluate control effect and security of 20% tebufenozide SC against Spodoptera exigua Hübner,which will provide technical support for its promotion and utilization.[Method] By using foliar spray method,the control effects of different concentration 20% tebufenozide SC and 25 g/L deltamethrin EC against S.exigua were determined.[Result] 20% tebufenozide SC has better control effects on S.exigua.After spraying 3 d and 7 d,the control effects of 20% tebufenozide SC each treatment could reach 81% and 84%,wh...
