【摘要】 为明确10%醚菊酯悬浮剂对稻水象甲的防治效果,2011年开展了田间药效试验。结果表明,10%醚菊酯悬浮剂对稻水象甲防效良好,且起效快,对水稻安全。药后10 d,10%醚菊酯悬浮剂120和150 g/hm~2的校正防效分别为89.0%和93.5%。建议10%醚菊酯悬浮剂在水稻分蘖中后期施用,有效成分用药量120～150 g/hm~2。若稻水象甲发生较重,可适当增加药剂用量。更多还原

【Abstract】 In order to verify the control effect of ethofenprox 10% SC on Lissorbqptrus oryzqphilus Kuschel, field efficacy trials were carried out. The results showed that the efficacies of ethofenprox 10% SC 120-150 g/hm~2 on Lissorbqptrus oryzqphilus Kuschel were 89.0%-93.5% at the 10 th day after treatment. The insecticide had quick bioactivity and was safe to rice. Ethofenprox 10% SC was suitable to be applied at the mid-late tillering stage of rice, and the optimum dosage was 120-150 g/hm~2.更多还原
