The efficacy of fenvalerate (EC, dust, and LVC), deltamethrin (2.8 EC), monocrotophos (36 SL), quinalphos (25 EC), methyl- parathion (2% dust), and chlorpyriphos (25 EC) was studied on chilli crop against Spodoptera litura Fab.Fenvalerate in EC and dust formulations was most effective, followed by deltamethrin.The dissipation of fenvalerate residues was faster in dust and EC formulations than in LVC.Terminal residues of fenvalerate fell below the maximum residue limit (0.2 ppm) in 15-21 days.
