摘要
2016年在田间比较了4.5%高效氯氰菊酯乳油、4.5%高效氯氰菊酯·马拉硫磷乳油、40%毒死蜱乳油、20%哒嗪硫磷乳油4种杀虫剂对苹果桃小食心虫的防治效果。研究结果表明,4.5%高效氯氰菊酯乳油·马拉硫磷乳油1 500倍液、20%哒嗪硫磷乳油800倍液的防效显著优于其它两种药液,高效氯氰菊酯和马拉硫磷混合使用效果优于高效氯氰菊酯单一使用的效果。
Control effects of 4 kinds of pesticide( 4. 5% beta-cypermethrin EC,4. 5% beta-cypermethrin & malathion EC,40% chlorpyrifos EC,20% pyridaphenthion EC) to Carposina niponsnsis in the field were compared in 2016. The results showed that the control effects of 4. 5% beta-cypermethrin & malathion EC 1500 x and 20% pyridaphenthion EC were significantly better than that of the two others. The control effect of beta-cypermethrin mixed with malathion was better than that of using beta-cypermethrin only.
