Abstract: An experiment on the efficacy of botanical extracts in comparison with a synthetic insecticide against whitefly on cotton crop was conducted at New Developmental Farm, The University of Agriculture, Peshawar, Pakistan during 2013. Two botanical extracts Datura alba 5% and Parthenium hystophorous 5% were applied in comparison with imidacloprid (250 g/acre i.e.,). Minimum number of whitefly/leaf/plant (0.38), (1.25), (1.35), (1.49), (1.75) and (1.84) was recorded after 24hrs, 48hrs, 72hrs, 7 days, 10 days and 15 days respectively in plots treated with imidacloprid followed by D. alba and P. hystophorous. Maximum number (4.00), (5.32), (5.87), (6.24), (6.75) and (6.94) of whitefly/leaf/plot was recorded in control plot. The study recommends the use of D. alba and P. hystophorous extracts for the effective management of whitefly in cotton crop.
