Persistence of acephate and cypermethrin in/on okra and cropped soil

Author(s): MU Mayannavar, CS Patil, BV Deore, SA Landge and PN Guru
Abstract: Persistence of acephate and cypermethrin in/on okra was studied after application of insecticides at fruit initiation stage. Acephate @ 560 and 1120 g a.i. ha-1 and cypermethrin @ 50 and 100 g a.i. ha-1 were applied twice at an interval of 10 days. The initial residues dissipated with half life of 1.83 and 1.83 days in case of acephate and 2.38 and 2.00 days in case of cypermethrin at recommended and double the recommended dose, respectively. Considering the LOQ of 0.05 mg kg-1, Pre-Harvest Interval (PHI) of seven days and five days can be suggested for acephate and cypermethrin for safe consumption of okra fruits.
