A research program was designed to check the efficacy of different insecticides against cabbage aphid during ‘rabi’ season of 2017-18 and 2018-19. From the results it concluded that malathion 50 % EC (82.10 %) was most effective as it cause maximum reduction in population of aphids w.r.t control, followed by nimbecidine 0.03 % EC (71.77 %) whereas, Bacillus thuringiensis var. kurstaki 0.05 % WP (49.93 %) was found least effective insecticide. However, two sprays were found more effective in managing the population of aphid rather single spray. Persistence and residual toxicity of the most effective insecticide i.e., malathion 50 % EC revealed that it was persisted up to 15 days in cabbage at both single and double dose with half life value 1.78 and 2.40, respectively. The average residues of malathion at both dose in cabbage was found below MRL (Maximum Residue Limit) i.e., 3.0 mg kg-1.
