三种不同药剂及施药方法对花生蛴螬的防效

目的]寻找适宜的防治花生蛴螬的药剂及施药方法。方法]比较了辛硫磷30CS、毒死蜱30CS和吡虫啉10SC这3种不同药剂以及拌种、灌根和穴喷雾3种不同的施药方法对花生蛴螬的防治效果及其对花生的保果效果。结果]采用穴喷雾法施用毒死蜱30CS防虫效果最好,达87.5%;穴喷雾法对花生的保果效果最好,达71.2%;辛硫磷30CS灌根处理的产量最高,15穴花生产量达931.9 g。结论]3种药剂均对蛴螬有较好的防治效果,而穴喷雾处理对蛴螬的防治效果及对花生的保果效果最优。

The Control Effect of Three Different Pesticides with Different Application Methods on Peanut White Grub

Objective] The study tried to find the suitable reagents and method for the prevention and control of white grub.Method] In this study,we investigated three different pesticides （phoxim 30CS,chlorpyrifos 30CS and imidacloprid 10SC） with three different application methods （seed-dressing,root-irrigation and acupoint injection） on peanut grubs control.Result] The white grubs controlling effect was the best which can reach 87.5％ with chlorpyrifos 30CS by acupoint injection.Acupoint injection was the best treatment for peanut fruit protecting.The peanut weigh of 15 holes was the highest with phoxim 30CS by root-irrigation which can reach 931.9 g.Conclusion] All three pesticides could protect peanut from white grub damage,moreover,acupoint injection was the best treatment for white grubs controlling and fruit protecting.
