[Method] Cottonseed oil EC and soybean oil EC were mixed with 20% imidacloprid EC and 0.5% avermectin WE respectively, Schizaphis graminum were handled with dipped method,synergistic effects of vegetable oil EC on imidacloprid and avermectin were analyzed. [Result] Cottonseed oil EC and soybean oil EC had obvious synergistic effect on 20% imidacloprid EC and 0.5% avermectin WE. Corrected mortality of 20% imidacloprid EC＋cottonseed oil EC（0.10＋10.00, 0.10＋5.00, 0.10＋3.33 and 0.05＋10.00 ml/L）, 0.5% avermectin WE＋cottonseed oil EC（1.00＋10.00, 1.00＋5.00, 0.50＋10.00 and 0.50＋5.00 ml/L）and 20% imidacloprid EC＋soybean oil EC（0.10＋10.00, 0.10＋5.00, 0.10＋10.00 and 0.05＋5.00 ml/L） were all over 90%. [Conclusion] Considered from control effect and economy angle, the mixture of cottonseed oil EC or soybean oil EC with 20% imidacloprid EC, and the mixture of cottonseed oil EC with 0.5% avermectin WE could be used to control S. graminum.展开更多
