增效吡虫啉新制剂2 .5 %蚜虱立克乳油防治棉蚜、麦蚜 ,每亩制剂用量为12 .5～25mL和15～30mL,l～15d的防治效果分别为97.l%～100%和90 .8 %～100% ;防治桃蚜稀释2000～4000倍液 ,1～15d的防效为94 .9%～100 % 。
Synergistic imidacloprid 2.5EC was used to control Aphis gossyii and Schizaphis graminum.At the dosage of 4.7～9.4g a.i./hm2 and 5.6～11.2g a. i./hm2, the control effect were 97.1%～100%(1～15 days after application)and 90.8～100%(1～15 days after application) respectively.Using 2000～4000 times diluents of synergistic imidacloprid 2.5EC,the control effect on Myzus persicae was 94.9%～100%(1～15 days after application).Results showed the fast and residua1 effect were better than those of the tested insecticides on this three species of aphid.
