| 摘 要： | 采用气相色谱法及田间试验方法，研究了甲氰菊酯在豌豆中的残留消解动态，并对其安全使用技术进行试验。结果表明，甲氰菊酯在豌豆中原始沉积量因不同施药处理有较大的差别，施用量越大原始沉积量也越高；残留消解动态均符合一级动力学方程，不同施用量的降解速率基本相似，降解系数（︱k︱）=0.167 8±0.001 3，半衰期（DT50）为4.1～4.2 d，降解99 %所需要的时间（T99）为27.1～27.7 d。按常规方法施用甲氰菊酯有效成分5.00 g·（667 m2）-1，施药1次或间隔7 d连续施药2次，末次施药后第14天的残留量均＜0.5 mg·kg-1，第24天的残留量均＜0.1 mg·kg-1，产品质量安全水平分别符合我国叶菜类蔬菜MRL和日本豆类蔬菜MRL的要求。

| Abstract: | The residual degradation dynamics of fenpropathrin in pea were studied by method of GC-ECD and field experiment.Meanwhile,the application technology experiment was researched.The result showed that,the original sediment of fenpropathrin was very different as the different application treatment in pea.The more fenpropathrin was applied,the higher original sediment seemed.The residual degradation dynamics of fenpropathrin in pea were followed first order kinetic equation.The degradation rates were identical b... |
