无人机低空喷雾氟啶虫胺腈防治棉花蚜虫效果

Control Efficacy of Cotton Aphids by Unmanned Aerial Vehicles Spraying Sulfoxaflor at Low Altitudes

应用无人机(UAV)低空喷雾22%氟啶虫胺腈悬浮剂进行防治棉花蚜虫的田间试验。结果表明,该药剂及施药方法对棉蚜防治效果显著,3d防效93%~99.4%,15d防效75.9%~83.9%。22%氟啶虫胺腈悬浮剂高浓度药液低空喷雾对棉花生长安全。

The field experiments indicated that sulfoxaflor 22% SC used by low altitude spraying through unmanned aerial vehicles （UAV） presented significant effect to control cotton aphid with the control rate of 93% to 99.4% at three days after treatment and of 75.9% to 83.9% at fifteen days after treatment. Sulfoxaflor 22% SC is safe to the cotton growth applied by UAV at low altitude to control cotton aphid.
