The aqueous extracts of twenty plants were screened by agar diffusion method for their antibacterial activity against Xanthomonas campestris pv. campestris, a causal organism of black rot of cabbage and cauliflower. Xanthomonas campestris pv. campestris was found most sensitive to the leaf extract of Camellia sinensis. Some of the other plants such as Acacia arabicae, Aegle marmelos, Acacia catechu, Achyranthus asper, Asparagus racemosus, Azadirachta indica, Callistemon lanceolatus and Acacia fernesiana, also showed the inhibitory effect against the test bacteria.
