A field experiment was conducted to evaluate the bio-efficacy of Indoxacarb 9% + Emamectin benzoate 1% SC against chilli fruit borer, Helicoverpa armigera for two consecutive years. Maximum fruit borer reduction (93.36 % and 90.20%) was recorded in the plants treated with Indoxacarb 9% + Emamectin benzoate 1% SC @ 50.0 g a.i. /ha, followed by Indoxacarb 9% + Emamectin benzoate 1% SC @ 40.0g.a.i./ ha (79.59% and 82.36%) and Emamectin benzoate 5% @10.0 g.a.i./ ha, (77.04% and 80.39%) . Minimum chilli fruit borer population reduction in the plots treated with Indoxacarb 14.5% SC@ 60.0 g a.i./ha (74.49% and 78.04%) followed by Indoxacarb 9% + Emamectin benzoate 1% SC @30.00g.a.i./ha, (61.73% and 66.67%), respectively in Kharif 2018 and 2019 season. The maximum yield (196.50 q/ha) was recorded from the plots treated with Indoxacarb 9% + Emamectin benzoate 1% SC @ 50.0 g a.i. /ha followed by Indoxacarb 9% + Emamectin benzoate 1% SC at 100 g a.i/ha (185.85 q/ha). The yield increase was also in high order in these treatments.
