摘要: The dissipation and residues of flutriafol in wheat and soil under field conditions in Beijing, Anhui and Shandong in China were determined based on high performance liquid chromatography. Flutriafol were extracted with acetonitrile and cleaned up by solid-phase extraction with florisil cartridges before UV detection. The limits of detection and quantification of flutriafol were 0.04 ng and 0.01 mg/kg for both wheat and soil samples, respectively. The mean recoveries ranged from 93.4% to 96.4%, with relative standard deviation between 3.8% and 6.8% at three spiked levels (0.01, 0.1, 1.0 mg/kg). Half-lives were 13.3, 9.9 and 13.6 days in soil, while 15.2, 10.8 and 9.2 days in wheat plant in Beijing, Anhui and Shandong, respectively. The terminal residues of flutriafol were below the maximum residue limit 0.02 mg/kg set by Japan in wheat when pre-harvest interval were 35 days.
