为评价氟环唑在小麦上使用的安全性，并建立其使用规范，对氟环唑在小麦及土壤中的残留及消解动态进行研究。采用田间试验方法研究氟环唑在小麦和土壤中的残留与降解情况，气相色谱外标法进行定量分析。结果表明：氟环唑的降解符合一级动力学方程。其在麦秆和土壤中的半衰期分别为10.6～26.9 d、6.3～24.0 d；在麦粒、麦秆和土壤中的最终残留量分别为0.002～0.818 mg/kg、0.002～2.400 mg/kg、0.002～0.411 mg/kg。采收间隔期为30 d时，氟环唑在麦粒中的最终残留量低于MRL值（0.05 mg/kg），符合标准要求。

In order to evaluate the safety and residue dynamics of epoxiconazole in wheat and soil, the final residues and dissipation dynamics were studied by field trials in 2011 and 2012. The target pesticides were determined by GC. The degradation of epoxiconazole in wheat and soil accorded with the first order kinetics equation, and its half-lives were 10.6-26.9 d and 6.3-24.0 d, espectively. The final residues of epoxiconazole were 0.002-0.818 mg/kg, 0.002-2.400 mg/kg and 0.002-0.411 mg/kg in wheat, wheat straw and soil, espectively. The final residues of epoxiconazole in wheat were all less than the MRL values.
