Biorational management of brinjal shoot and fruit borer (leucinodes orbonalis guenee) in mid hills of meghalaya

Ajit Tripura, ML Chatterjee, Rachna Pande and Sandip Patra

The present field experiments were conducted to evaluate some biorational pesticides against brinjal shoot and fruit borer (BSFB) under field condition during kharif season of 2015 and 2016 at ICAR Research Complex for North Eastern Hill Region, Umiam, Meghalaya, India. The treatments viz. chlorantraniliprole 18.5 SC (0.4ml/l), spinosad 45 SC (0.5ml/l), chlorfenapyr 10 SC (2ml/l), indoxacarb 14.5 SC (1ml/l), Bacillus thuringiensis (Bt) (2g/l), azadirachtin 0.03EC (5ml/l), Metarhizium anisoplae (2.5g/l), Beauveria bassiana (2.5g/l), chlorpyriphos 20EC (2.5 ml/l) were applied thrice at fifteen days interval starting from initiation of BSFB infestation. Mean shoot infestation was minimum in chlorantraniliprole plots (6.32%) followed by spinosad, chlorfenapyr, indoxacarb. Among bio-pesticides, Beauveria and Bt were found effective treatments in reducing shoot infestation. Chlorantraniliprole recorded lowest fruit infestation (8.25%) and highest marketable fruit yield (250.30q/ha) followed by spinosad and chlorfenapyr.
