Summary:ABSTRACT Objective:To evaluate the insecticidal, antimicrobial and antioxidant activities of bulb extracts ofAllium sativum(A. sativum).Methods:Dried bulbs ofA. sativum were extracted with different solvents and evaluated for insecticidal, antimicrobial and antioxidant activities.Results:Aqueous and methanol extracts showed highest insecticidal activity (mortality rate of81% and 64% respectively) against the larvae ofSpodoptera litura (S. litura) at a concentration of1 000 ppm. With regard to antimicrobial activity, aqueous extract exhibited antibacterial activity against gram positive (Bacillus subtilis, Staphylococcus aureu,) and gram negative (Escherichia coliandKlebsiella pneumonia) strains and antifungal activity againstCandida albicans. While methanol extract showed antimicrobial activity against all the tested micro organisms except two (Staphylococcus aureus andCandida albicans), the extracts of hexane, chloroform and ethyl acetate did not show any anti microbial activity.
