摘　　要：[目的]探究哈速腾和激健2种助剂对甲维盐和乙基多杀菌素防治节瓜蓟马的增效作用及减量效果。[方法]采用喷雾法,将激健助剂2000倍、哈速腾1000倍分别添加到甲维盐、甲维盐与乙基多杀菌素混合液中,设置减量10%、20%、30%这3个梯度,与常规用量的药液对比,测定药液的雾滴密度、雾滴覆盖率,研究助剂对节瓜蓟马的防效。[结果]使用甲维盐防治蓟马时,添加哈速腾或激健助剂,能提高防效。使用甲维盐和乙基多杀菌素防治节瓜蓟马时,添加哈速腾助剂,能减少30%农药用量,添加激健助剂,能减少20%农药用量。[结论]生产上使用甲维盐和乙基多杀菌素防治蓟马时,建议添加哈速腾助剂,可减少农药使用量,提高防效。[Objective]To explore the synergistic effect and reduction effect of two kinds of adjuvants,Hasauteng and Jijian,on the control of thrips with emamectin benzoate and spinetoram.[Method]The field efficacy trials were conducted by spraying.The recommended dose of Emamectin benzoate and Spinetoram tank-mixed with Hasuteng 1000-fold dilution and Jijian 2000-fold dilution,respectively,to determine the droplets,coverage ratio of droplet,and field control on Thrips palmi karny.[Result]When using emamectin benzoate to prevent and control thrips,adding Hasuteng or Jijian adjuvant could improve the control effect.When using emamectin benzoate and spinetoram to control thrips,adding Hasuteng adjuvant could reduce the amount of pesticides by 30%,and adding Jijian adjuvant could reduce the amount of pesticides by 20%.[Conclusion]When using emamectin benzoate and spinetoram to control thrips,it was recommended to add Hasuteng adjuvant in practice,which could reduce the use of pesticides and improve the control effect.
