Bioefficacy of neem and Bt against pod borer, helicoverpa armigera in chickpea

Abstract

An experiment was conducted during the year 2007 - 08 and 2008 - 09 to evaluate the bioefficacy of certain biopesticides against pod borer, Helicoverpa armigera in chickpea. Neem Seed Kernel Extract (NSKE 5%) was found most effective in reducing the larval population and pod damage. Yield and Cost Benefit ratio (C: B ratio) was also found maximum in the NSKE treated plots suggesting that these integrated pest management components can be incorporated in the chickpea management.
