10%溴虫氟苯双酰胺悬浮剂对西瓜蓟马的田间防效

Field Control Efficacy of Broflanilide 10% SC Against Thrips palmi

明确10%溴虫氟苯双酰胺悬浮剂对西瓜蓟马的防治效果,为生产上推广应用提供理论依据。2016—2017年在山东省烟台市依照田间药效试验准则进行田间药效试验。结果表明,10%溴虫氟苯双酰胺悬浮剂25～30 g a.i./hm^2处理,药后7 d对西瓜蓟马的防效分别为89.23%～92.11%、88.04%～90.68%,优于对照药剂10%溴氰虫酰胺可分散油悬浮剂50 g a.i./hm^2(防效分别为86.83%、85.18%)。10%溴虫氟苯双酰胺悬浮剂是一种防治西瓜蓟马较为理想的药剂,具有较好的应用和推广前景。

The study aimed to evaluate the field efficacy of broflanilide 10% SC against Thrips palmi to provide scientific basis for its application to production. According to guidelines on efficacy evaluation of pesticides, the field trials were conducted in Yantai City of Shandong Province during 2016-2017. The results showed that the control efficacy of broflanilide 10% SC against T.palmi at 25-30 g a.i./ha was 89.23%~92.11% and 88.04%-90.68% after spraying 7 d, which performed better control effects than that of cyantraniliprole 10% OD at dosage of 50 g a.i./ha （with control efficacy of 86.83% and 85.18%, respectively）. So, broflanilide 10% SC could be used as an ideal insecticide for controlling T.palmi, and it had good application and promotion prospects.
