ABSTRACT
Persistence of cypermethrin, chlorpyriphos, and profenofos in tomato and soil were studied following application of two pre-mix formulations of insecticides viz. Roket 44EC (profenofos 40% + cypermethrin 5%) and Action-505EC (chlorpyriphos 50% + cypermethrin 5%) at recommended (0.8-1.0 L ha(-1)) and double dosage (1.6-2.0 L ha(-1)). In all the treatments residues persisted beyond 7 days in tomato fruits. Half-life values were calculated from first-order dissipation kinetics. In the case of Roket 44EC, residues of cypermethrin on fruits dissipated with half-life of 2.0-3.6 days, whereas residues of profenophos dissipated with the half-life of 2.2-5.4 days. In the case of Action-505EC, residues of chlorpyriphos and cypermethrin dissipated from fruits with the half-life values of 2.9-3.3 and 2.5-4.8 days, respectively. In soil, residues of profenofos persisted for 7-15 days, whereas residues of chlorpyrophos and cypermethrin persisted for 0-7 days only.
