几种复配剂对稻飞虱的防治效果比较

摘要

比较了6种复配剂对稻飞虱的防效,结果表明:噻嗪异丙威、吡蚜噻嗪酮、丙威毒死蜱的防效优异,吡虫乙酰甲、吡虫仲丁威的防效较好,以上5种复配剂均显著优于吡虫杀虫单,因此噻嗪异丙威、吡蚜噻嗪酮、丙威毒死蜱可作为防治稻飞虱的常规品种,吡虫乙酰甲、吡虫仲丁威作为替换品种,在防治过程中注意经常轮换药剂品种.%The comparison of the control efficacy of six pesticide mixtures against rice planthoppers was conducted in this paper. The results showed that the control efficacies of thiazide isoprocarb, pymetrozine buprofezin and isoprocarb chlorpyrifos were the best, and those of imidacloprid methacholine and imidacloprid fenobucarb were better. The control efficacies of the above five pesticide mixtures were significantly superior to that of imidacloprid monosultap. Thiazide isoprocarb, pymetrozine buprofezin and isoprocarb chlorpyrifos were recommended as the conventional varieties controlling rice planthoppers, while imidacloprid methacholine and imidacloprid fenobucarb could be used as replacement varieties. The pesticides should be frequently rotated in the pest control.
