Field trials were conducted to evaluate the efficacy of insecticides against Bemisia tabaci and ToLCV incidence in tomato during summer seasons of 2008 and 2009. Among the insecticides, profenophos @ 500 g a.i/ha and thiamethoxam @ 25 g a.i/ha effectively controlled the whitefly population and reduced the ToLCV incidence and improved the yield of tomato fruits. Higher net returns of Rs.83,070/- and Rs. 79,580/- were also realized with Profenophos and thiamethoxam sprays with maximum cost:benefit ratio of 1:5 and 1:4:95, respecitvely.
