摘　　要：化学-生物农药复配已经成为农业上防治作物病虫害的重要手段,但化学农药氯虫苯甲酰胺和生物农药印楝素配伍对亚洲玉米螟防治效果和酿酒高粱安全性的影响尚未明确。通过盆栽试验,比较不同氯虫苯甲酰胺-印楝素组合对亚洲玉米螟防效和酿酒高粱生长情况的影响。结果表明:1)200 g/L氯虫苯甲酰胺悬浮剂(75 mL/hm^(2))+0.3%印楝素乳油(1200 mL/hm^(2))对亚洲玉米螟的防效最佳,第1、第3和第7天的防效与单一施用200 g/L氯虫苯甲酰胺悬浮剂(150 mL/hm^(2))的防效差异均无统计学意义;2)氯虫苯甲酰胺和印楝素单独施用、联合配伍对酿酒高粱的生长均无影响(与对照处理差异无统计学意义)。综上,氯虫苯甲酰胺与印楝素配伍可减少化学农药氯虫苯甲酰胺的使用量,且对高粱植株相对安全。The combination of chemical and biological pesticides has become an important means to control crop diseases and pests in agriculture,but the control effects of chlorantraniliprole combined with azadirachtin on Ostrinia furnacalis Guenee and the sasfety for brewed sorghum is still unclear.In this study,we compared the effects of different combinations of chlorantraniliprole-azadirachtin on Ostrinia furnacalis Guenee control and the growth of brewed sorghum through a pot experiment.The results showed that:1)The control effect of 200 g/L chlorantraniliprole(75 mL/hm^(2))and 0.3%azadirachtin(1200 mL/hm^(2))combination was the best,and was consistent with that of 200 g/L chlorantraniliprole(150 mL/hm^(2))alone at 1,3,and 7 days after application.2)The effect of azadirachtin and chlorantraniliprole alone or in combination on sorghum growth were negligible(no significant difference compared with control).Therefore,the combination of chlorantraniliprole and azadirachtin could reduce the amount of chlorantraniliprole,and was safety for brewed sorghum.
