摘要
以1代水稻二化螟和2代水稻二化螟为靶标,对一种新型邻氨基苯甲二酰胺类杀虫剂氯虫苯甲酰胺防治水稻二化螟进行了研究。结果表明:18.5%氯虫苯甲酰胺SC对水稻二化螟的防效高,持效期长,能有效控制水稻二化螟的危害。18.5%氯虫苯甲酰胺SC防治1代二化螟,药后36d保苗效果达90%～100%,杀虫效果达92%～100%;18.5%氯虫苯甲酰胺SC防治2代二化螟,药后30d白穗率控制在0.3%～1.2%,受虫害株率控制在0.2%～1.8%,防效可达85%～98%。
Chilo suppressalis Waleker is one of the important pests in the rice, and the control of the pest increased hardly with the decreasing of many pesticides controls for pesticides misapply inducing resistance of the pest. In this paper, firsr generation and second generation of Chilo suppressalis Waleker were conducted as test objects to investigate control of a new pesticide （chlorantraniliprole） with preparation of chlorantraniliprole 18.5% SC to Chilo suppressalis Waleker. The results showed that chlorantraniliprole 18.5% SC had effective control to Chilo suppressalis Waleker for its excellent control efficacy and long persistence period. Seedling protection efficacies were between 90 and 100%, and insecticidal efficacies were between 92 and 100% 36 days after application of chlorantraniliprole 18.5% SC for first generation Chilo suppressalis Waleker control. The dead panicles were between 0.3 and 1.2%, and the rates of damaged rice plants were between 85 and 98% 30 days after application of chlorantraniliprole 18.5% SC for second generation Chilo suppressalis Waleker control.
