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.
建立并验证了一种改良的单甲脒在水稻植株和环境中的残留分析方法。在 GAP 条件下的田间试验中研究了单甲脒的残留动态和最终残留量。在 0.05、0.5 和 1 mg kg(-1) 的添加水平下，回收率在 75.0%至 109.2%之间，相对标准偏差（RSD）为 1.2-5.1%（n = 5）。消解实验表明，单甲脒在水中、土壤和水稻植株中的半衰期（T(1/2)）分别为 1.1-1.9、1.4-2.1 和 1.3-2.1 天。在收获前间隔（PHI）为 21 和 30 天时，土壤中单甲脒残留量为 0.01-0.06 mg kg(-1)，水稻植株中残留量为 0.01-0.19 mg kg(-1)，去壳糙米中残留量为 0.01-0.09 mg kg(-1)。
