Uniconazole residue dynamics and final residues in supervised field trials at GAP conditions were studied. The residue levels and dissipation rate of uniconazole was detected by LC-MS. At fortification levels of 0.04, 0.2 and 2 mg kg(-1), recoveries ranged from 78.7 % to 100.9 % with RSDs of 0.1 %-4.6 % (n = 5). The dissipation experiments showed the half-lives (T1/2) of uniconazole in soil and wheat plants were 2.9-3.3 and 3.8-4.4 days, respectively. At pre-harvest intervals (PHI) of 45 and 60 days, uniconazole residue were no detectable or below the limit of quantification (LOQ) in soil, wheat plants and wheat.
