| 摘 要： | 在使用剂量相当的情况下,70%吡虫啉水分散粒剂对小麦穗期蚜虫的田间防治效果与可湿性粉剂一致,使用24～40g/hm2时对小麦蚜虫具有较理想的防治效果,药后1d的防效即达65%左右,到14d时效果仍接近90%,具有较好的速效性与持效性,不同剂型之间无明显差异。

| Abstract: | The efficacy of imidacloprid WG against wheat earing aphids was the same as that of imidacloprid WP with identical dosage. It was no obvious discrepancy between two formulations. The result showed that the quick and continuing result had been obtained with using imidacloprid WG in 24 ~ 40 g a.i./hm2, and the efficacy was 65% after 1 day and about 90% after 14 days. |
