An experiment was laid during Rabi 2019 at central research field, SHUATS, Prayagraj, U.P. Bio-pesticides and combination were used with seven treatments and three replications. Experiment was carried out in Randomized Block Design. The results obtained based on pest population, grain yield and B: C ratio are as follows, Emamectin benzoate (220gm/ha) + Indoxacarb (30gm/ha) (2.19) and (1932.67kg/ha) was most effective treatment followed by Indoxacarb (60gm/ha) (3.3) (1880.33kg/ha), NSKE (25kg/ha) + Indoxacarb (30gm/ha) (3.6) (1584.33kg/ha), Neem oil (5ml) + Indoxacarb (30gm/ha) (3.9) (1435.00kg/ha), Beauveria bassiana (400gm/ha) + Indoxacarb (30gm/ha) (4.4) (1332.00kg/ha) and Bacillus thuringiensis (750-1000gm/ha) + Indoxacarb (30gm/ha) (5.2) (1224.33kg/ha). The highest cost benefit ratio was obtained from Emamectin benzoate + Indoxacarb (1:2.70) ˃ Indoxacarb (1:2.65) ˃ NSKE + Indoxacarb (1:2.23) ˃ Neem oil + Indoxacarb (1:2.03) ˃ Beauveria bassiana + Indoxacarb (1:1.84) ˃ Bacillus thuringiensis + Indoxacarb (1:1.64) ˃ control (1:1.21).
