摘　　要：为明确新型杀虫剂环丙氟虫胺对田间二化螟的防治效果及其应用技术,在早稻二化螟枯鞘初现期开展了药效试验。结果表明,20%环丙氟虫胺悬浮剂对二化螟具有良好的防效。总施药剂量、持效期与防控效果均呈二次函数关系。20%环丙氟虫胺悬浮剂施用剂量为20 m L(667 m^(2)),连续用药2次(间隔10 d),持效期达到20 d,校正防效在85%以上,植保无人机飞防总体防控效果在95%以上。20%环丙氟虫胺悬浮剂在试验剂量下对水稻安全无药害。To clarify the control effect and application technology of the new insecticide cyproflanilide against Chilo suppressalis in early rice,field trials were carried out at the early stage of the appearance of withered sheaths in early rice.The results showed that cyproflanilide 20%SC had a good control effect on Chilo suppressalis.The total applied dosage,the duration of effectiveness both showed a quadratic function relationship with the control effect.The optimal application dosage of cyproflanilide 20%SC was 20 m L (per 667 m~2),usage count was 2 times (interval of 10 days).Under these conditions,the persistent period could reached 20 days,and the corrected control effects were over 85%,and the control effect of plant protection drones was over 95%.Cyproflanilide 20%SC was safe to rice at the tested dosage.
