Abstract:The disappearance rate of Imidan® (N-(mercaptomethyl)phthalimide-S-(O,O-dimethylphosphorodithioate)) was studied in a sandy loam and a loam soil. The effect of soil composition, moisture, pH, and microorganisms on persistence was also evaluated. Residues of Imidan and its thiol analog, Imidoxon, were determined according to a phosphomolybdate colorimetric method. Imidan degraded very rapidly in both soils. The time for 50% degradation in a sandy loam soil and a loamy soil was in the range of 3–19 days. The major factor associated with degradation of Imidan in soils appears to be spontaneous hydrolysis.
