不同药剂拌种对花生地下害虫蛴螬的防治效果

Control Effect of Different Pesticides on Underground Pest Grub in Peanut Field

[目的]筛选防治花生地下害虫蛴螬的最佳药剂。[方法]采用不同药剂拌种,筛选防治花生地下害虫蛴螬的药剂。[结果]3种药剂对花生地下害虫蛴螬的防治效果显著。但各处理间有显著差异性,60%吡虫啉FS的防治效果较好,88.18%,且损果率较低,仅6.46%,分别较30%噻虫嗪·氟虫腈WS和70%噻虫嗪WS低22.66和14.33个百分点。[结果]综合考虑,生产上防治花生地下害虫蛴螬的推荐最佳药剂为60%吡虫啉FS。

[ Objective ] The aim was to screen out optimal agents to control underground pest grub in peanut field. [ Method] The pesticide to prevent and control underground pest grub in peanut field was chosen from three pesticids. [ Result] The result showed that three pesticides have obvious control effect on white grubs, but the difference was significant. The control effect of 60% imidacloprid was 88.18% , and dam- age fruit rate was 6.46%, and were 22.66 and 14.33 percentage points higher than that of 70% thiamethoxam and 30% thiamethoxam ~ fipronil respectively. [ Conclusion] 60% imidaeloprid can be used for field control of underground pest grub of peanut.
