Talpur Imtiaz A. Nizamani 1200221The studies on the evaluation of different insecticides for the control of mustard aphid, Lipaphis erysimi(kalt..) on mustard crop were carried out in the field. The recommended doses o four insecticides viz., Thiodan 50 EC (endosulfun) , Kapaphos 400EC (profenofos), Xiangmen 60 SL (methamodophos) and monophos 40 SCW (Monocrotophos) were sprayed twice at fortnight intervals. The results on reduction percentages in the population of aphids indicated that all the insecticides had higher initial killing effects, however, Monophos was comparatively more toxic and persistent insecticide against this insect pest on mustard. The plots sprayed with monophos yielded significantly higher than rest of the insecticides under trial.]]>Ahamad, M. and R.U.
