摘　　要：[目的]探索桶混助剂对30%螺虫乙酯·噻虫胺悬浮剂的增效作用。[方法]以桃叶为靶标,测定SP-017助剂、Silwet 806、罗普瑞助剂对30%螺虫乙酯·噻虫胺悬浮剂表面张力、接触角、持留量等指标的影响,并进行桃树桑白蚧药效试验。[结果]30%螺虫乙酯·噻虫胺悬浮剂桶混罗普瑞助剂后,表面张力与接触角均减小,持留量增加。罗普瑞助剂以667~1000 mg/L(制剂用量)桶混使用时,对桃树桑白蚧的防效显著提升。[结论]罗普瑞助剂可显著增强30%螺虫乙酯·噻虫胺悬浮剂的防效。[Aims]Control effects of spirotetramat·clothianidin 30%suspension concentrate(SC)added tank-mixed adjuvants were investigated in this study.[Methods]The surface tension,contact angle and maximum retention of spirotetramat·clothianidin 30%SC were determined using peach leaf as a target after the addition of adjuvant SP-017,Silwet 806 or Luopurui,and field efficacy trials against Pseudaulacaspis pentagona were carried out.[Results]The surface tension and contact angle to peach leaf decreased while maximum retention increased after the addition of adjuvant Luopurui.Field trials showed that adjuvant Luopurui tank-mixed at 667-1000 mg/L(formulation)improved the field control effect of spirotetramat·clothianidin 30%SC against P.pentagona.[Conclusions]Control effect of spirotetramat·clothianidin 30%SC could be enhanced by adding adjuvant Luopurui.
