Rajesh Kumar, MK Mahla, Beerendra Singh, KC Ahir and NC Rathor

Relative efficacy of different bio-pesticides and newer insecticides treatments against sucking insect pest on brinjal was evaluated in field condition at the Horticulture Farm of Rajasthan College of Agriculture, MPUAT, Udaipur during kharif from August 2015 to January 2016. The result showed that the three applications of Imidacloprid 17.8 SL (0.5 ml /lit) was found significantly most effective, which caused maximum population reduction per cent of sucking insect pest of brinjal aphid, 78.10, jassid, 76.55, and whitefly, 82.21 per cent. It was followed by fipronil 5 SC (1 ml /lit) with 74.00, 72.00, 74.37 and emamectin benzoate 5 SG (0.2 g/lit) with 70.82, 70.35, 71.00 per cent mean population reduction. NSKE 5 % was found least effective aphid, jassid and whitefly with 55.00, 53.82, 53.33 It was followed by azadiractin 3000 ppm was found least effective aphid, jassid and whitefly with 58.72, 59.75, 64.80 and Spinosad 0.1 ml /lit, was found least effective aphid, jassid and whitefly with 61.76, 69.69, 67.30 the treatments and caused lowest mean reduction population of aphid, jassid, whitefly. The highest marketable yield of 28.69 kg /plot was recorded in case of Imidacloprid 17.8 SL (0.5 ml /lit). It was followed by fipronil 5 SC (1 ml / lit), and emamectin benzoate 5 SG (0.2 g/lit), which yielded 27.69, 24.43 kg/plot and respectively. NSKE 5 %, azadiractin 3000 ppm, and Spinosad 0.1 ml /lit yielded the lowest marketable of 15.90, 18.06, 22.93 and 23.51kg/plot.
