摘    要:目的]筛选防治花生蛴螬的30%毒死蜱微囊悬浮剂最佳田间使用量。方法]以30%毒死蜱微囊悬浮剂3750、5625、7500 g/hm2为处理,以40%毒死蜱乳油7500 g/hm2为正常对照,以清水处理为空白对照,调查花生被害情况,计算各处理防效。结果]使用30%毒死蜱微囊悬浮剂3750~7500 g/hm2防治花生蛴螬效果显著好于对照药剂40%毒死蜱乳油,但30%毒死蜱微囊悬浮剂处理间防效差异不显著。结论]30%毒死蜱微囊悬浮剂幼虫防效及保果效果均较好,可在生产上推广使用。

关 键 词:30%毒死蜱微囊悬浮剂  蛴螬  田间药效试验  最佳用量

Abstract:Objective]The study aimed to select the optimal dosage of 30% microcapsule suspension of chlorpyrifos against peanut white grub in field trials.Method]The 3 750,5 625,7 500 g/hm2 dosage of 30% chlorpyrifos microcapsule suspension was designed as treatments,meanwhile 7 500 g/hm2 40% chlorpyrifos E C and water were regarded as normal control and blank control,respectively.The harmfulness condition of peanut was investigated,and the control effect was calculated.Result] The control effects of 3 750~7 500 g/hm2 30% chlorpyrifos microcapsule suspension were obviously higher than 40% chlorpyrifos E C,but no significant differences among the 30% chlorpyrifos microcapsule suspension treatments were observed.Conclusion]With good performance on grub control and protecting fruits,30% chlorpyrifos microcapsule suspension could be generalized in field.
Keywords:30% microcapsule suspension of chlorpyrifos  White grub  Field efficacy trials  Optimal dosage
