| 摘 要： | 利用高效气相色谱法研究了40%毒死蜱乳油在番茄果实中的残留降解动态。结果表明,在推荐剂量75 mL/hm2下,其降解半衰期为2.49 d;在加倍剂量150 mL/hm2下,降解半衰期为2.55 d,药后7 d的残留量为0.200 0 mg/kg,符合我国对毒死蜱在番茄上残留≤0.5 mg/kg的要求。 |

| Abstract: | The residue dynamics of chlorpyrifos in tomato was studied through gas chromatography analysis.The results showed that recommended dose concentration 75 mL/hm2 of chlorpyrifos,the half-life of chlorpyrifos residue was 2.49 day,and being treated with the high concentration 150 mL/hm2,the half-life of the residue was 2.55 day,After 7 day,the final residue of chlorpyrifos in tomato was 0.200 0 mg/kg,agreed with the safety qualification of chlorpyrifos in tomato in China. |
