摘　　要：试验表明 ,5 %锐劲特SC和 90 %敌百虫原粉混配对 3代三化螟引起的水稻白穗有较好的防治效果 ,混用的防效较锐劲特单用为好。在三化螟大发生年份用锐劲特 3 0 0ml/hm2 +敌百虫 12 0 0g/hm2 防治 2次 ,对白穗的平均防效达 93 .94%。The experiment showed that the efficacy of the tank mixture of regent 50SC with trichlorfon was better than that of regent 50SC directly used at the same rate on the control of the paddy yellow rice stem borer(Scirpophaga incertulas). The control efficiency of the tank mixture of 300 ml of regent 50SC with 1200g of 90% trichlorfon per hectare was up to 93.94%.
