助剂对节瓜蓟马田间防效的影响.

[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 1 000-fold dilution and Jijian 2 000-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.
