Dissipation and persistence of certain organophosphorus insecticides in/on Okra
Author(s): CS Patil, BV Deore, YS Saindane and SA Landge
Abstract: Persistence of some organophosphorus insecticides viz. acephate, triazophos and profenophos in okra was studied following two applications at recommended dose. Residues persisted upto 5, 7, and 10 days for triazophos, acephate and profenophos, respectively. Half-life values were calculated from first-order dissipation kinetics. In case of acephate, residues on okra fruits dissipated with half-life of 1.88 days, whereas residues of triazophos and profenophos dissipated with the half-life of 1.89 and 1.59 days, respectively. Considering 0.05 mg/kg as LOQ, 7, 10 and 15 day can be considered safe for harvesting residue free okra fruits in case of triazophos, acephate and profenophos, respectively.
