| 摘 要： | 采用高效液相色谱分析技术测定了噻螨酮在桃中的残留动态和最终残留。噻螨酮的最低检出量为1 ng,最低检出浓度为0.05 mg/kg,在桃中的平均回收率为82.4%～97.5%,相对标准偏差为3.00%～5.97%,符合农药残留分析的要求。试验结果表明:噻螨酮在桃中的半衰期为6.8 d,按高浓度药液施药7 d后桃中最高残留量为0.79 mg/kg。

| Abstract: | The HPLC method was used to determine the degradation dynamics and final residues of hexythiazos in peach.The minimum detectable quantity of hexythiazos was 1 ng and its minimum detectable concentration was 0.05 mg/kg.Its average recovery rate was 82.4%~97.5% with the variation coefficients of 3.00%~5.97%,so it could meet the requirements for pesticide residue analysis.The half life of hexythiazos was 6.8 days in peach,so with the higher concentration of 5% hexythiazos,the minimum residue in peach was 0.79 mg/kg after applied for 7 days. |
