[目的]监测噻嗪酮在柑橘和土壤中的残留量.[方法]采用气相色谱法测定噻嗪酮在柑橘和土壤中的残留.[结果]噻嗪酮在柑橘全果中的平均回收率为96.17%~97.38%,变异系数为6.10%~9.07%;在果肉中的平均回收率为95.24%~105.46%,变异系数为3.30%~6.01%;在果皮中的平均回收率为88.76%~93.64%,变异系数为5.12%~6.27%;在土壤中的平均回收率为97.79%~104.3%,变异系数为2.45%~9.21%.噻嗪酮在柑橘和土壤中的消解动态以及最终残留结果表明,在湖南长沙、浙江杭州和贵州贵阳3地柑橘中的消解半衰期分别为7.65、7.64、8.40 d,土壤中的消解半衰期分别为13.75、9.97、10.18 d.[结论]在柑橘上使用25%的噻嗪酮悬浮剂兑水剂,按照推荐使用剂量为166.7~250.0 mg/L,施药2~3次的情况下,噻嗪酮在柑橘上的安全期可定为14 d.

[Objective] The paper was to detect the residue of buprofezin in citrus and soil.[Method] Gas chromatography (GC) method was used to measure the residue of buprofezin in citrus and soil.[Result] The average recovery rate of buprofezin in entire citrus fruit was 96.17%-97.38%, and the variation coefficient was 6.10%-9.07%; the average recovery rate in pulp was 95.24%-105.46%, and the variation coefficient was 3.30%-6.01%; the average recovery rate in peel was 88.76%-93.64%, and the variation coefficient was 5.12%-6.27%; the average recovery rate in soil was 97.79%-104.3%, and the variation coefficient was 2.45%-9.21%.The degradation dynamics and the final residue results of buprofezin in citrus and soil showed that the degradation half-lives in citrus in Changsha (Hunan), Hangzhou (Zhejiang) and Guiyang (Guizhou) were 7.65, 7.64 and 8.40 d, and the degradation half-lives in soil in three places were 13.75, 9.97 and 10.18 d, respectively.[Conclusion] When 25% buprofezin SC watered agent were sprayed in citrus fruits for 2-3 times according to the recommended dose of 166.7-250.0 mg/L, the safe period of buprofezin in citrus could be set as 14 d.
