摘　　要：为探索200 g·L^(-1)氯虫苯甲酰胺及其与150 g·L^(-1)茚虫威分别单用以及混用对玉米草地贪夜蛾的防治效果,在衢州市开化县杨林镇川南新村玉米种植基地中进行田间药效示范试验。试验发现,供试剂量下施用200 g·L^(-1)氯虫苯甲酰胺和150 g·L^(-1)茚虫威对玉米生长无不良影响,对草地贪夜蛾均具有较好的防治效果,对草地贪夜蛾为害的玉米具有较好的保株和保叶效果。施药后10 d杀虫防效在83.33%~90.48%,保株防效在85.3%~89.0%,保叶防效在92.73%~95.79%。To evaluate the control efficiency of Spodoptera frugiperda in maize by 200 g·L^(-1) chlorantraniliprole and 150 g·L^(-1) indoxacarb,respectively and simultaneously,field trial was experimented in Chuannanxincun of Yanglin town,Kaihua County,Quzhou City.The results showed that the 200 g·L^(-1) chlorantraniliprole and 150 g·L^(-1) indoxacarb had no adverse effects on the growth of maize,had good control effects on Spodoptera frugiperda,and the protection of maize damaged by Spodoptera frugiperda.Ten days after pesticides were applied,the effect of pest control,rate of plant protection and rate of leaf protection was in the range of 83.33%-90.48%,85.3%-89.0%,92.73%-95.79%,respectively.
