Residues of propargite were estimated in okra fruits by high performance liquid chromatography following single application of Omite 57 EC @570 and 1,140 g a.i./ha. Residues of propargite were confirmed by high performance thin layer chromatography. The average initial deposits of propargite were observed to be 1.36 and 3.32 mg/kg, respectively, which were below its maximum residue limit of 2 mg/kg. The residue levels of propargite dissipated below its limit of quantification of 0.02 mg/kg after 7 days at single dose and after 10 days at double dose. The half-life values (T ₁(/)₂) of propargite were worked out to be 0.79 and 0.73 days, respectively, at recommended and double the recommended dosages.
丙硫克百威在蕹菜上的残留 经高效液相色谱法测定，在施用奥灭净 57EC @570 和 1140 克有效成分/公顷后，蕹菜中的丙硫克百威残留量。丙硫克百威残留量由高效薄层色谱法确认。丙硫克百威的平均初始沉积量分别为 1.36 和 3.32 毫克/千克，低于其最大残留限量 2 毫克/千克。在单剂量 7 天后和双剂量 10 天后，丙硫克百威的残留水平低于其限量的 0.02 毫克/千克。丙硫克百威的半衰期（T ₁(/)₂）分别为 0.79 和 0.73 天，在推荐剂量和推荐剂量的两倍下。
