The present study was conducted to study the effectiveness of the plant crude extract against some animal and plant pathogenic microbes. Antimicrobial activity was assessed by agar well diffusion method against nine bacterial strains. The crude extracts (pet.ether, chloroform and methanol crude extracts) tested against 9 bacterial strains (3 plant pathogenic and 6 animal pathogenic).
