The research was carried out to determine the persistence of acephate and chlorpyriphos on cucumber crop and soil along with the effect of decontamination processes. The initial deposits due to single dose of acephate (560 g a.i. ha-1) and chlorpyriphos (300 g a.i. ha-1),) were 0.640 and 0.980 mg kg-1, respectively in cucumber fruits. However, at double dose the initial deposits were 1.123 and 1.860 mg kg-1 for respective insecticides. Acephate and chlorpyriphos residues persisted in cucumber fruits upto 5 and 7 days at single dose and 7 and 10 days at double dose, respectively. The residues of acephate and chlorpyriphos on fruits reduced to half in less than 2 days with safe waiting periods of 9 and 10 days, respectively. Among various decontamination processes, peeling was found most effective which provided upto 91.36 per cent relief from chlorpyriphos and 71.07 per cent in case of acephate.
