摘要
[目的]为了筛选防治甘蔗蛴螬的理想药剂,采用随机区组排列法结合甘蔗大培土布施6种杀虫剂进行田间药效试验.[结果]5％异丙特丁硫磷颗粒剂防治蛴螬效果最佳,残留虫口数最少,为1.67头/m2,蔗根受害情况也最轻,受害率仅为5.56％,两者相对防效均为最高,分别为76.19％、93.57％.其次是8％毒死蜱·辛硫磷颗粒剂和8％杀螟单·辛硫磷颗粒剂.其他杀虫剂对蛴螬均有一定防效,但效果不甚理想.[结论]结合甘蔗大培土,选施5％o异丙特丁硫磷颗粒剂75 kg/hm2、8％毒死蜱·辛硫磷颗粒剂60 kg/hm2和8％杀螟单·辛硫磷颗粒剂60 kg/hm2等药剂,可有效防治甘蔗蛴螬,保护蔗根免受为害.
Abstract
[Aims] In order to screen out effective insecticides against white grubs in sugarcane fields, control effect trails were carried out using randomized block design with six insecticides at large earth-up. [Results] Among six insecticides tested, the best insecticide against white grubs was isopropyl-terbufos 5% GR, followed by chlorpyrifos · phoxim 8% GR and cartap-phoxim 8% GR. In the treatment with isopropyl-terbufos 5% GR, the number of residual white grubs was the minimum (1.67 heads/m2), and the root infestation rate was the lowest (5.56%), both the relative control effects were maximum, 76.19 and 93.57%, respectively. The effects of other insecticides against white grubs were not very good. [Conclusions] To control effectively white grubs and to protect sugarcane roots from the damage of white grubs, isopropyl-terbufos 5% GR (75 kg/ha), chlorpyrifos-phoxim 8% GR (60 kg/ha) and cartap ? Phoxim 8% GR (60 kg/ha) should be selected and used at large earth-up in sugarcane fields.
