建立了杀虫单在水稻植株和环境中的残留分析方法。研究了GAP条件下杀虫单残留动态和田间试验中的最终残留。在0.05、0.5和1 mg kg−1的强化水平下，回收率范围为75.0%-109.2%，RSD为1.2-5.1%（n = 5）。杀虫单在水、土壤和水稻中的半衰期（T1/2）分别为1.1-1.9、1.4-2.1和1.3-2.1天。在收获前21天和30天的间隔期内，杀虫单在土壤中的残留量为0.01-0.06 mg kg− 1，在水稻植株中为0.01-0.19 mg kg− 1，在糙米中为0.01-0.09 mg kg− 1。
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 (T1/2) 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−1in soil, 0.01–0.19 mg kg−1in rice plants, and 0.01–0.09 mg kg−1in husked rice.
