摘要: Productivity of gram crop is strongly affected by pod borer Helicoverpa armigera, which damages 90-95% during favorable weather conditions due to its high fecundity, migratory and polyphagus nature, resistance against insecticides. They damage the trichome stem pods ultimately decrease growth productivity chick pea crop. Single binary combinations vermiwash with biopesticides show significant effect on growth, plant pest infestation Helicoverpa. The was observed in per cent after spraying neem oil custard apple leaf extract. combination animal dung municipal solid wastes aqueous garlic extract caused maximum reduction rate H. armigera. vermiwsah obtained from buffalo were more effective for better as well management
