【摘要】A field experiment was conducted to determine the efficiency of 0.4% chlorantraniliprole granules to control rice striped stem borer. The result showed that the control efficiency was high when using 600 g, 700 g, 800 g/667m^2 of 0.4% chlorantraniliprole granules. Using the insecticide 10 days before the peak occurrence of the second instar larvae of rice stem borer, the control efficiency 21 days, 30 days and 40 days after application was 86.18%-100%, 84.62%-96.41%, and 82.28%-92.86%, respectively. And the spraying of 700-800 g/667m^2 resulted in the best efficiency, in which both the speed and the lasting time were far better than the control insecticides. Well-distributed spraying the insecticides 10 kg mixed fine soil grains per 667 m^2 before the peak incidence of the second instars of rice stem borer was the best option in extension.%通过田间试验研究0.4%氯虫苯甲酰胺颗粒剂及其不同剂量对水稻二化螟的防治效果。结果表明：0.4%氯虫苯甲酰胺颗粒剂在防治期内施用600 g/667m^2、700 g/667m^2、800 g/667m^2防治二化螟均具有较好防治效果。于水稻二化螟2龄盛发期前10 d施药,药后21 d防治效果为86.18%-100%、药后30 d防治效果为84.62%-96.41%、药后40 d防治效果为82.28%-92.86%,持效期达40 d。其中700-800 g/667m^2药剂效果最佳,速
效性高、持效期长,明显优于对照药剂。生产上推广使用时,以水稻二化螟2龄盛发期前10 d按剂量每667 m^2拌细土10 kg均匀撒施最好。 【总页数】3页(311-313)
