3种杀虫剂底施防治花生蛴螬试验初报

Control Effect of Three Types of Insecticides as Base Fertilizer Against Peanut Grubs

测定了3种常见杀虫剂0.06%噻虫胺颗粒剂、3%辛硫磷颗粒剂和5%毒死蜱颗粒剂在防治花生蛴螬上的效果,结果表明3种颗粒剂对蛴螬均有防治效果,同时也有一定增产作用,其中以0.06%噻虫胺颗粒剂效果最佳,其防效与增产率分别为76.9%和9.2%。在生产上防治花生蛴螬时,可以考虑选择0.06%噻虫胺颗粒剂,该款颗粒剂为药肥产品,同时含有噻虫胺和花生生长所需氮磷钾,用量参考春花生900 kg/hm^(2)。

The aim of this study was to evaluate the control effects of three organophosphorus pesticides(0.06%clothianidin GR,3%phoxim GR,5%chlorpyrifos GR)against peanut grubs.The results showed that all treatments had significant impact on both yield and peanut grubs control,with 0.06%clothianidin GR exhibiting the best effect.The control efficiencies for 0.06%clothianidin GR were 76.9%,with a yield-increasing efficiency of 9.2%.The product also contains 0.06%clothianidin and nutrients,and provides a dosage reference of 900kg/hm^(2) for spring peanut.
