| 摘 要： | 采用气相色谱（GC-ECD）法研究了天津、吉林两地百菌清在番茄果实及土壤中残留量的动态变化。结果表明：在番茄果实上，百菌清的半衰期为3d，10-11d可降解90％以上；在土壤中，百菌清的半衰期为5～7d，16-24d可降解90％以上。最终残留试验的结果表明，按推荐剂量和高剂量分别施药3次和5次，于最后一次施药后的1、3、7d进行采收，番茄上百菌清的残留量分别为0～0．936mg／kg，符合国家标准GB2763的规定。

| Abstract: | The method of GC-ECD was carded out to detect the dynamic changes of chlorothalonil residues in tomatoes and soils in Tianjin and Jilin Province. The results show that the half-life of chlorothalonil in tomatoes was 3 d, and the chlorothalonil degraded above 90% after 10-11 d. The half-life of chlorothalonil in soils was 5-7 d, after 16-24 d, the chlorothalonil degraded above 90%. In addition, the final residues of chlorothalonil in tomatoes were 0-0.936 mg/kg. All of them are according with the national standard GB2736. |
