摘　　要：[目的]筛选甘蓝甜菜夜蛾防治药剂氯虫苯甲酰胺的替代产品。[方法]每种药剂采取登记用量上下限作为试验剂量,用喷洒药剂悬浮液的方法进行田间试验。[结果]施药后3 d,10%四氯虫酰胺悬浮剂60 g a.i./hm2防效97.87%,200 g/L四唑虫酰胺悬浮剂30 g a.i./hm2防效96.11%,5%氯虫苯甲酰胺悬浮剂33.75 g a.i./hm2防效95.30%;药后15 d 10%四氯虫酰胺悬浮剂60 g a.i./hm2防效89.86%,200 g/L四唑虫酰胺悬浮剂30 g a.i./hm2防效88.07%,5%氯虫苯甲酰胺悬浮剂33.75 g a.i./hm2防效80.81%。[结论] 3种双酰胺类杀虫剂防治甘蓝甜菜夜蛾对作物安全,在氯虫苯甲酰胺抗性较强的地区,建议选择四氯虫酰胺和四唑虫酰胺作为替代产品。[Aims] This study aims to screen out the substitute pesticides for chlorantraniliprole for control of Spodoptera exigua. [Methods] The upper and lower limits of the registered dosage were used as the experimental dosage. The field tests was carried out by spraying insecticide suspension. [Results] Three days after treatment, the control effect of tetrachlorazamide 10% SC 60 g a.i./ha was 97.87%, 200 g/L tetraniliprole SC 30 g a.i./ha showed 96.11% control, and chlorantraniliprole 5% SC 33.75 g a.i./ha indicated 95.30% control. After 15 days, the control effect of tetrachlorazamide 10% SC 60 g a.i./ha was 89.86%, tetraniliprole 200 g/L SC 30 g a.i./ha showed 88.07% control, and chlorantraniliprole 5% SC 33.75 g a.i./ha indicated 80.81% control. [Conclusions] The results showed that three novel diamide insecticides were safe to crops. In the areas with high resistance to chlorantraniliprole, it is suggested to choose tetrachlorazamide and tetraniliprole as substitutes.
