ABSTRACT
In the present study, three insecticides viz. methamidophos @ 1.0lha, fenpropathrin @ 1.2l/ha and metasystox @ 1.4l/ha were tested for the control of aphid population on Brassica campestris. The experiment was conducted during October 2013 to April 2014. Crop season following a randomized complete block design (RCBD) with four replications and six treatments in the research farm of Babar Agricultural Farm at Old Shuja Abad Road, Multan. Different insecticides showed different mortality of aphid population. Of the three insecticides tested, methamidophos resulted in more than 80% mortality in the aphid population and more than 30% increase in the yield, whereas fenpropathrin and metasystox produced mortality of 80% and 72% respectively. The result of this study indicated that the insecticide methamidophos is more effective as compared to that of fenpropathrin and metasystox.
