研究了哒螨酮与三氯杀螨醇复配对柑桔红蜘蛛的药效。结果表明，哒螨酮与三氯杀螨醇按８：１２复配的克螨王活性最高，共毒系数为１０７．９。通过大田验证，质量浓度２０％克螨工在柑桔上的药效明显优于质量浓度２０％三氯杀螨醇，与质量浓度１５％哒螨酮相当，而防治费用降低２０％～４０％。 The effect of compounding pyridaben and dicofol on citrus red spider was studied. The results showed that Pyridaben and dicofol at 8:12 compounded mite mite king activity, the co-toxicity coefficient was 107.9. Through field validation, the concentration of 20% grams mite workers in citrus was significantly better than the mass concentration of 20% dicofol, with the mass concentration of 15% pyridaben, and prevention and control costs reduced by 20% to 40%.
