Abstract:

Field evaluation of nano based biopesticides Bacillus thuringiensis, Nomura earileyi and Beauveria bassiana against S. litura larvae resulted the highest mean per cent reduction was 77.00 per cent in Bt treated with CaO barley based solid formulation in three days after treatment, followed by 73.72 in CaO based B. bassiana talc formulations (T21), 68.44 per cent in CaO based N. rileyi broken rice formulations (T15) in seven days after treatment. Ten days after spraying the mean per cent reduction was ranged from 0.00 to 16.67 per cent. The results indicated that Bt grown on barley flour and with CaO nanoparticles was found as effective treatment with highest pod and haulm yield of 1993 kg ha-1, 3899 kg ha-1 respectively, followed by 1919 kg ha-1, 3828 kg ha-1 with Bt grown on barley flour with MgO nanoparticles during rabi, 2016. The similar trend was observed during rabi, 2017.
