摘　　要：[目的]系统地研究氟硅唑农药在苹果及土壤中的残留量，促进安全生产。【方法】建立了样品用乙腈溶液提取、吸附分散剂（PsA）净化后，通过液相色谱-紫外检测器测定，面积外标法定量的检测方法。[结果]方法检出限为9．9×10^-3mg/kg，平均回收率为71．5％-105．0％，相对标准偏差为2．4％-8．2％。【结论】方法简便、快速、准确度高、精密度好。[Aims] Systematically studied the residues of flusilazole in apple and soil to promote the safety production. [Methods] Samples were extracted by acetonitrile, purified by adsorption dispersant PSA, and＇ determined by HPLC-UV. [Results] The detectable limit of this method was 9.9× 10-3 mg/kg, the average recovery rate was 71.5-105.0%, the relative standard deviation was 2.4-8.2%. [Conclusions] The method was fast, simple and sensitive with good accuracy.
