摘　　要：为验证复配制剂1%联苯·噻虫嗪颗粒剂替代有机磷颗粒剂对甘薯小象甲的防治效果,及对甘薯产量和品质的影响,笔者于2021年在广东开展了4个田间示范试验。结果表明:1%联苯·噻虫嗪颗粒剂5kg/667m^(2)防治甘薯小象甲效果优良,平均防效77.60%,明显高于甘薯种植区常用的3%辛硫磷颗粒剂4kg/667m^(2)的防效48.52%,且甘薯平均增产达24.79%,也明显高于3%辛硫磷颗粒剂4kg/667m^(2)处理的12.37%。To verify the field efficacy of Bifenthrin and Thiamethoxam 1% GR replacing Organophosphorus GR against sweet potato weevil and the impact on the yield and quality, a total of 4 field trials were conducted in Guangdong Province.The results showed that Bifenthrin·Thiamethoxam 1% GR(Yingzhuang) had excellent control effects on sweet potato weevil at the application rate of 5kg/667m^(2),with an average control effect of 77.60%,which was significantly higher than 48.52%,provided by the commonly used product-phoxim 3% GR at the application rate of 4 kg/667m^(2),and that the average yield increase rate of sweet potato reached 24.79%,significantly higher than 12.37% in the control group.
