title: Dissipation and residue determination of fluoroglycofen-ethyl in soybean and soil by UPLC-MS-MS.
abstract: A rapid, highly selective, and sensitive method was developed for detecting fluoroglycofen-ethyl in soybean seed, plant, and soil using UPLC-MS-MS. The detection limits of fluoroglycofen-ethyl in soybean seed, plant, and soil were 0.5, 1, and 1 μg kg(-1), respectively. Recoveries ranged from 83.4% to 99.2%, in which intra-day RSDs were from 1.3% to 6.7% and inter-day RSDs were from 1.9% to 7.0%. In the dissipation study, the half-lives of fluoroglycofen-ethyl were 34.8 (Shanxi) and 48.5 h (Heilongjiang) in soil and 43.3 h in soybean plant in both locations. The residues of fluoroglycofen-ethyl in all samples were below LODs 30 days before and during harvest.
