Effect of insecticides on insect pests of brinjal.

Two foliar sprays of bifenthrin @ 50 g a.i./ha or an insecticide mixture, chlorpyriphos +cypermethrin @ 1000 ml/ha were effective in managing leafhopper and whiteflies. However, borer infestation might be minimized by two sprays of either cartap hydrochloride @ 500 g a.i./h or endosulfan @ 700 g a.i./ha or carbosulfan @ 750 ml/ha and also observed to inproduce high yield (24.93, 23.60 & 24.78 MT/ha) as well as cost benefit ratio (1:3.16,1:3.25 & 1:3.45), respectively as compared to control that gave 15.03 MT/ha with C:B of 1:2.15.
