Economics of botanicals and biopesticides especially in reference to management of Helicoverpa armigera in chickpea crop

Anil Kumar, MK Tripathi, Umesh Chandra and Ram veer

The field experiment was carried out at the Agriculture Farm, Department of Entomology, Tilak Dhari Post Graduate College, Jaunpur during Rabi 2010-11 and 2011-12 with three replications and seven treatments of Biopesticides, against Helicoverpa armigera. The Biopesticides like NSKE, Bacillus thuringiensis, Neem leaf extract, Neem oil, Nimbicidine and nuclear polyhedrosis virus in reducing the infestation of gram pod borer, Helicoverpa armigera and providing a higher net return per rupee invested. The higher grain yield of 24.07 Q./ha and22.65 Q/ha was recorded with the application of NSKE @ 5 per cent /ha during both years. The most favourable cost benefit ratio was obtained from the plot treated with Neem leaf Extract @ 5 per cent 31.82 and 22.22 followed by Neem leaf Extract @ 5 per cent 31.82 and 22.22, Neem oil @ 2 per cent 22.59 and 20.94, NSKE @ 5 per cent 19.68 and 15.06, Nimbecidine @ 2 per cent 16.16 and 15.04, Ha NPV @ 450 LE/ ha 9.34 and 6.28, Bt.1 kg /ha 6.40 and 4.91 during both years.
