在４０％乐果乳油２５００倍药液中加入０．０１％—０．０４％浓度的表面活性剂ＡＰＳＡ－８０，其表面张力降低３９．５３％—５５．１０％，在芥兰叶表面和背面上接触角度分别降低４８．４９％—５３．２６％和４１．３０％—４７．８１％；在乐果药液中分别加入０．０２％和０．０４％浓度的ＡＰＳＡ－８０，对萝卜蚜幼蚜触杀毒力提高２．２倍和６．８倍；在乐果２５００倍药液中分别加入０．０１％、０．０２％和０．０４％浓度的ＡＰＳＡ－８０，对菜蚜最高防效分别为９５．２１％、９１．１５％和９６．４８％，明显高于乐果２５００倍和乐果１５００倍的防效，与乐果１０００倍的防效相当。
The surfactant APSA-80 with concentration of 0.01% -0.04% was reduced by 39.53% -55.10% in 40% dimethoate 2500 times solution, The angle of contact on the back decreased 48.49% -53.26% and 41.30% -47.81% respectively; APSA-80 was added to the dimethoate solution at concentrations of 0.02% and 0.04% respectively, Aphis gossypii larval aphid contact toxicity increased by 2.2 times and 6.8 times; dimethoate 2500 times solution were added 0.01%, 0.02% and 0.04% concentration of APSA-80, on the food The highest control effect of aphids was 95.21%, 91.15% and 96.48%, respectively, which was significantly higher than 2500 times of dimethoate and 1500 times of dimethoate, which was equivalent to 1000 times of dimethoate.
