采用田间试验方法,借助气相色谱检测技术,建立了氟氯氰菊酯在甘蓝和土壤中的残留分析方法,研究了其残留降解动态。结果表明,氟氯氰菊酯在甘蓝中的降解比土壤中快,在甘蓝中的降解半衰期为5.3~6.5d;在土壤中的降解半衰期为8.1~11.6d,该药属较易降解农药。

A field experiment was conducted to reveal the degradation rate and residual dynamics of cyfluthrin in cabbage and soil.A gas chromatography was employed for the determination of the residue of cyfluthrin.The results showed that the degradation rate of cyfluthrin was more rapid in cabbage than in soil.The half-lives were 5.3~6.5d in cabbage and 8.1~11.6d in soil.
