研究了GAP条件下监督田间试验中烯效唑的残留动态和最终残留。采用LC-MS法检测烯效唑的残留量和消解速率。在0.04、0.2和2 mg kg−1强化水平下，回收率范围为78.7%-100.9%，RSD为0.1%-4.6%（n = 5）。烯效唑在土壤和小麦植株中的半衰期（T1/2）分别为2.9-3.3和3.8-4.4天。在收获前45和60天的间隔（PHI），土壤，小麦植株和小麦中未检出烯效唑残留或低于定量限（LOQ）。
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.
