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。
In order to screen out the pesticides with high efficiency, low toxicity and low residual to control planthoppers, the control efficacy of 4 different pesticides such as 10% etofenpro as fifth generation planthoppers was set up. The results showed that 10% Ester suspension 100 ml / 667 m2, 25% buprofezin WP 50 g / 667 m2 + 80% dichlorvos 100 mg / 667 m2, 25% pymetrozine WP 25 g / 667 m2 For rice planthoppers Better anti-efficiency, can promote the application of production, it is recommended to rotate between different doses.
