Abstract
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.
