The antibacterial investigation of Punica granatum (Pomegranate rind) extract was performed against Agrobacterium tumefaciens, Erwinia chrysanthemi, Pseudomonas pisi, Pseudomonas solanacearum, Xanthomonas malvacearum and isolated plant pathogenic bacteria as test organisms. This screening of antibacterial activity of Punica granatum rind extract was determined by agar- well diffusion method. Among them, Agrobacterium tumefaciens (23mm) and Pseudomonas pisi (22mm) are found to be more sensitive and Xanthomonas malvacearum (18mm) is found to be less sensitive. And among the isolated ones all are found to be the highly sensitive but bacteria isolated from Cotton Leaves (33mm), Tuwar Seeds (32mm) and Lemon Leaves(30mm) are found to be the more sensitive. And bacteria isolated from Tuwar Leaves (29mm) and Cotton Bolls (29mm) are found to be the less sensitive against Punica granatum rind extract. Thus, results obtained indicate that, Punica granatum fruit rind posse’s potent antibacterial activity as compare with standard antibiotic Streptomycin against all the tested plant pathogenic bacteria. This antibacterial activity was due to the presence of bioactive phytochemical.
