The present investigation was conducted at the Horticultural farm, Rajasthan College of Agriculture, Udaipur during Kharif 2018-19. Among the seven treatments, chlorantraniliprole 18.5 SC (76.23%) was found to be the most effective against fruit borer in terms of per cent population reduction and cost benefit ratio, followed by indoxacarb 14.5 SC (74.47%) and spinosad 45 SC (73.38%). The treatment HaNPV 250 LE (29.34%) proved to be the least effective. Emamectin benzoate 5 SG (72.70%) and Novaluron 10 EC (55.64%) were observed in the middle order of efficacy. All the insecticides significantly increased the yield of marketable fruits over control.
