30%高效氯氟氰菊酯·噻虫嗪悬浮剂对小麦蚜虫的田间药效试验,结果表明,30%高效氯氟氰菊酯·噻虫嗪悬浮剂3~4m L/667m2处理区药后1d、3d、7d、14d防效分别为74.78%~85.95%、90.85%~96.78%、98.70%~100.00%、98.14%~99.86%,与对照药剂的防效基本相当,持效期优于对照药剂2.5g/L高效氯氟氰菊酯微乳剂处理区。试验剂量对小麦安全。在小麦蚜虫始盛期,以商品量3~4m L/667m2(有效成分13.5~18g/hm2)叶面喷雾为宜对蚜虫有着很好的防效,且持效期长。宜在小麦蚜虫防治中推广应用。
The field efficacy test of 30% lambda-cyhalothrin and thiamethoxam on wheat aphid showed that 30% lambda-cyhalothrin and thiamethoxam 3 ~ 4m L / 667m2 after treatment The control effects were 74.78% -85.95%, 90.85% -96.78%, 98.70% -100.00% and 98.14% -99.86% at 1d, 3d, 7d and 14d, respectively. Pharmacy 2.5g / L Lambda-cyhalothrin microemulsion treatment area. Test dose on wheat safety. In the beginning of wheat aphid, the commercial application of 3 ~ 4m L / 667m2 (active ingredient 13.5 ~ 18g / hm2) foliar spray should have a good control effect on aphids, and the persistence period is long. Should promote the application of wheat aphid control.
