摘要

The efficacy of some locally available medicinal plant powders and their alcoholic extracts, v/r. rhizome of Sweet flag, kernel of Neem, seeds of Karanj, leaves of Nirgudi, Swastik. Tulsi and Sadaphuli was evaluated at 1% and 2% dose concentration @ 100 g seeds as pre-storage treatment against pulse beetle, Callosobnichm chinemis L. on Bengal gram, Cicer urietinum seeds. Among the plant products, rhizome powder and alcoholic extracts of Sweet flag offered maximum protection i.e. decreases in percentage of egg laid, seed damage and weight loss, which was closely followed by powder and alcoholic extracts of Neem, Karanj and Nirgudi at same dose concentrations.
