文摘

Fenoxaprop-P-ethyl is widely applied in rice ecosystem for weeding. A simple and accurate method for determination of fenoxaprop-P-ethyl and its metabolite fenoxaprop-P in paddy water, paddy soil, rice plants, husked rice, straw and rice hull was established by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS-MS). Recoveries of fenoxaprop-P-ethyl and fenoxaprop-P in these matrices at three spiking levels ranged from 75.1 to 102.8% with relative standard deviations (RSDs) of 1.6 to 8.2%. The limits of detection (LODs) of fenoxaprop-P-ethyl and fenoxaprop-P were 0.003 mg/kg. Fenoxaprop-P-ethyl dissipated rapidly to fenoxaprop-P in paddy water and soil during hours. The half-life of fenoxaprop-P-ethyl in rice plants was 1.26-.41 days, and the half-life of fenoxaprop-P in paddy water, paddy soil and rice plants was 1.87-.93, 1.61-.31 and 1.82-.93 days. The ultimate residues of fenoxaprop-P-ethyl and fenoxaprop-P in paddy soil, straw, rice hull and husked rice samples at harvest were not detectable or below 0.01 mg/kg.
