Author(s): SG Khorasiya, KL Raghvani, AM Bharadiya and JB Bhut

Abstract: Among the bio-pesticides HaNPV@ 250 LE ha-1 was found most effective against H. armigera which recorded significantly the highest per cent mortality(80.61 and 82.61%) at 50 per cent flowering and 50 per cent pod formation stage, respectively which also noticed significantly registered the highest grain yield (1264 kg ha-1). B. thuringiensis @1.0 kg ha-1 was also found equally effective against H. armigera. In case of insecticides, chlorantraniliprole 0.006 per cent found significantly most effective which recorded the highest per cent mortality (83.59 and 85.59%) at 50 per cent flowering and 50 per cent pod formation, respectively and also recorded 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).
