Abstract
- A modified method for the analysis of monosultap residue in rice plant and environment was developed and validated. Monosultap residue dynamics and final residues in supervised field trials at GAP conditions were studied. At fortification levels of 0.05, 0.5 and 1 mg kg(-1), it was shown that recoveries ranged from 75.0% to 109.2% with RSDs of 1.2-5.1% (n = 5). The dissipation experiments showed the half-lives (T(1/2)) of monosultap in water, soil and rice plants were 1.1-1.9, 1.4-2.1 and 1.3-2.1 days, respectively. At pre-harvest intervals (PHI) of 21 and 30 days, monosultap residue were 0.01-0.06 mg kg(-1) in soil, 0.01-0.19 mg kg(-1) in rice plants, and 0.01-0.09 mg kg(-1) in husked rice.
