%X Residue dynamics and terminal residue of flubendiamide 19.8% suspension concentrate (SC) in rice and field environment were measured by ultra performance liquid chromatography (UPLC). As flubendiamide and its metabolite were applied at a range of concentrations from 0.05 to 1.0 mg·kg-1, average recoveries of them in soil, water, rice straw, rice grain and rice hull samples ranged from 78.2% to 104.8%, with variation coefficients of 1.1%-4.4%. One-year and three-area results showed that the half-life of gradation for flubendiamide was 9.8 to 17.3 d in water, 10.8 to 22.4 d in soil, and 7.6 to 17.3 d in rice plants, respectively. Residues of metabolite NNI-des-iodo in water were detected, but not in soil or rice plants. When flubendiamide was applied at the recommended dose, its residue in rice grain on the 10th day after application was lower than 0.5 mg·kg-1, the maximum residue limit allowed by US for agricultural chemical residues in rice.
