| Abstract: | The field trials of 3% emanectin benzoate ME on Cnaphalocrocis medinalis Guenee were carried out. The results showed that at 1 d, 3 d, 7 d after application the efficacy of 3% emanectin benzoate ME at 1.35 g a.i./666.7m^2 was 70.33%, 76.09%, 80.95%, and the efficacy of 3% emanectin benzoate ME at 2.25 g a.i./666.7m^2 was 82.5%, 86.75%, 90.34%, but the efficacy of 40% chlorpyrifos EC at 30.0 g a.i./666.7m^2 was 65.67%, 70.34% and 73.23%, respectively. The result showed that 3% emanectin benzoate ME was better than 40% chlorpyrifos EC against Cnaphalocrocis medinalis Guenee. |
