不同农药对水稻制种田稻飞虱的防效试验

The Prevention and Control Test of Several Short-acting Pesticides on Rice Hopper

为筛选出高效、低毒、低残留的农药防治稻飞虱,设置了10%醚菊酯悬浮剂等4种不同药剂对第五代稻飞虱的防治效果试验,结果表明:10%醚菊酯悬浮剂100 ml/667m2、25%噻嗪酮可湿性粉剂50 g/667m2+80%敌敌畏乳油畏100 ml/667m2、25%吡蚜酮可湿性粉剂25 g/667m2对水稻稻飞虱均有较好的防效,可在生产上推广应用,建议不同药剂间轮换使用。

This study to select high efficiency, low toxicity, low residual pesticide rice planthopper, set up 10% ether chrysanthemum ester containing four different reagent to the fifth generation of rice planthopper control effect experiment, the results show that the ether 10% chrysanthemum ester containing 100 ml/667m2, 25% thiamethoxam oxazine ketone wettable powder 50 g/667m2 ＋ 80% dichlorvos 25% ec and 100 ml/667m2, pyrazole ketone of aphid wettable powder 25 g/667m2 of rice planthopper in rice all have good control effect, could be applied in the production, rotated suggest different reagents.
