摘要
[目的]筛选适合花生防治蛴螬的30%辛硫磷微囊悬浮剂最佳田间使用量。[方法]以30%毒死蜱微囊悬浮剂12000、15000、18000g/hm^2为处理,以40%辛硫磷乳油15000g/hm^2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%辛硫磷微囊悬浮剂12000~18000g/hm^2防治花生蛴螬效果显著好于对照药剂40%辛硫磷乳油,但30%辛硫磷微囊悬浮剂处理间防效差异不显著。[结论]30%辛硫磷微囊悬浮剂药效长、防效好,可在生产上推广使用。
[ Objective ] The study aimed to select the optimal dosage of 30% microcapsule suspension of phoxim against peanut white grub in field trials. [ Method ] The 12 000,15 000,18 000 g/hm^2 dosage of 30% phoxim microcapsule suspension was designed as treatments, meanwhile 15000 g/hm^2 40% phoxim 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 12 000 - 18 000 g/hm^2 30% phoxim microcapsule suspension were obviously higher than 40% Phoxim E C ,but no significant differences among the 30% phoxim microcapsule suspension treatments were observed. [ Conclusion ] With the advantages of good grub control effect and long action cycle ,30% microcapsule suspension of phoxim could be generalized in field.
