A simple, sensitive method for the analysis of flutriafol in wheat and soil was developed using high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). The dissipation dynamics and ultimate residue of flutriafol in wheat and soil were detected using the established method. The half-lives of flutriafol in wheat plant were 4.09 days (Hebei) and 1.54 days (Hubei), while in soil were 6.25 days (Hebei) and 3.16 days (Hubei), respectively. The final residues of flutriafol were below 0.5 mg/kg (MRL of EU) in wheat grain 28 days after the treatment.
采用高效液相色谱串联质谱法（HPLC-MS/MS）建立了一种分析氟环唑的简单、灵敏方法。采用所建立的方法检测了氟环唑在小麦和土壤中的消解动态和最终残留。氟环唑在小麦植株中的半衰期分别为 4.09 天（河北）和 1.54 天（湖北），在土壤中的半衰期分别为 6.25 天（河北）和 3.16 天（湖北）。施药 28 天后，小麦籽粒中氟环唑的最终残留量低于 0.5mg/kg（欧盟的 MRL）。
