Efficacy of bio-pesticides, insecticides alone and their combination against pod damage caused by Helicoverpa armigera in chickpea

Khorasiya SG, Raghvani KL, Bharadiya AM, Jethva DM and Bhut JB

A field experiment was conducted during Rabi season of 2011-12 and 2012-13 at instructional farm, Junagadh Agricultural University, Junagadh to find out efficacy of bio-pesticides, insecticides alone and their combination against pod damage caused by Helicoverpa armigera in chickpea. Among the bio-pesticides HaNPV@ 250 LE ha-1 was found most effective against H. armigera which recorded significantly lowest per cent pod damage at harvest (15.25 %) and registered the highest grain yield (1264 kg ha-1). Bacillus thuringiensis @1.0 kg ha-1 was also found equally effective against H. armigera. In case of insecticides, chlorantraniliprole 0.006 per cent found most effective, which recorded significantly the least per cent pod damage (13.78 %) with highest grain yield (1383 kg ha-1). In combination of insecticides and bio-pesticides HaNPV 125 LE ha-1 with chlorantraniliprole 0.003 per cent found significantly most effective. The highest ICBR i.e. 10.19 was observed in HaNPV @ 250 LE/ha which was followed by HaNPV @ 125 LE ha-1 + chlorantraniliprole 0.003 per cent (8.06).
