摘　　要：[Objective]The paper was to understand the control effect and the optimum dosage of 25% abamectin·etoxazole SC for controlling red spider in ornamental rose. [Method] Using stem-leaf spraying method,the control effect of 25% abamectin·etoxazole SC against red spider was determined. Significance of difference was examined by Duncan's new multiple range test( DMRT). [Result] The control effect of 25% abamectin · etoxazole SC sprayed at the dose of25-31. 25 mg a. i./kg on red spider was over 82. 0% at 21 d post spraying,higher than that of 110 g/L etoxazole SC sprayed at the dose of 27. 5 mg a. i./kg and1. 8% abamectin EC sprayed at the dose of 9 mg a. i./kg. [Conclusion]25% Abamectin·etoxazole SC sprayed at the doses of 25-31. 25 mg a. i./kg could effectively control the damage of red spider in ornamental rose,and can be widely used in production.[Objective]The paper was to understand the control effect and the optimum dosage of 25% abamectin·etoxazole SC for controlling red spider in ornamental rose.
