| 选用6种药剂，采用拌种、拌种+喷雾、喷雾3种施药方法，在甘肃省康乐县进行了双低春油菜田间油菜蚤跳甲防效比较试验，以油菜被害指数表示药剂的防治效果，选出适宜药剂与施药方法。结果表明：拌种处理中，毒死蜱被害指数最低（2~3叶期4.15%、4~5叶期20.38%、5~6叶期32.08%），氰戊·马拉松、甲维盐次之；拌种+喷雾处理中，氰戊·马拉松（1.83%、15.84%、25.16%）、甲维盐（6.20%、29.25%、29.24%）防效最佳，吡虫啉次之；喷雾处理中，氰戊·马拉松（5.24%、18.79%、29.17%）最佳，甲维盐、吡虫啉次之。氰戊·马拉松、辛硫磷、毒死蜱、甲维盐拌种、拌种+喷雾，甲维盐喷雾将最终死苗率控制在5%以内，大田示范试验中被害指数控制在40%以内，有效控制了对油菜的为害。由此，可以用毒死蜱、氰戊·马拉松、甲维盐、吡虫啉替代高毒农药甲拌磷防治油菜蚤跳甲。其中吡虫啉、甲维盐适宜喷雾，毒死蜱适宜拌种，氰戊·马拉松拌种或喷雾均适宜。 |
| 英文摘要: |
| Experiments were conducted to compare the control effects of Psylliodes punctifrons Baly by 6 pesticides and three methods (seed dressing, seed dressing+spraying, spraying) in double low rape fields in Kangle County of Gansu Province. The results showed that, with seed dressing, chlorpyrifos produced the lowest damage index, followed by fenvalerate malathion and emamectin benzoate chlorfenapyr. Through seed dressing+spraying, fenvalerate malathion, and emamectin benzoate chlorfenapyr had the best effects, followed by imidacloprid. Through spraying, fenvalerate malathion was the best, followed by emamectin benzoate chlorfenapyr and imidacloprid. Fenvalerate malathion, phoxim, chlorpyrifos and emamectin benzoate chlorfenapyr, through seed dressing and seed dressing+spraying, and emamectin benzoate chlorfenapyr through spraying, brought the final dead seedling rate in the range of 5%, and the damage index in the range of 40% in the field experimental demonstration. These results suggested that chlorpyrifos, fenvalerate malathion, emamectin benzoate chlorfenapyr and imidacloprid could replace phorate, in which imidacloprid and emamectin benzoate chlorfenapyr were suitable for spraying, chlorpyrifos for seed dressing, and fenvalerate malathion for both spraying and seed dressing. |
