An experiment was conducted to find out the most effective insecticide (s) for the control of mustard aphid, Lipaphis erysimi Kaltenback (Homoptera : Aphididae) in the field. Eight different insecticides, namely, Marshal 20 EC, Dimecron 100 EC, Malathion 57 EC, Zolone 35 EC, Perfekthion 40 EC, Ripcord 10 EC, Diazinon 60 EC, and Elsan 50 EC were applied as general application covering the whole plants. The mortality data recorded 24 and 48 hours after insecticidal treaments were subjected to statistical analysis. Significant difference was observed among the treatments at 1% level of probability. The results indicated that Marshal 20 EC, Zolone 35 EC and Perfekthion 40 EC - 2ml/litre of water were most effective insecticides in reducing aphid population.
