| Abstract | Wrightia tinctoria L. leaf hexane, methanol, chloroform, ethyl acetate and water extracts were screened against plant
pathogenic bacteria by in vitro. The extracts were tested using disc diffusion method and minimum inhibitory
concentration. Ethyl acetate and methanol extracts showed significant antibacterial activity against gram negative
bacteria; the MIC was 50 μg/ml for Xanthomonas campestris and Erwina sp. Study shows Wrightia tinctoria leaves
possessed potent antimicrobial properties against plant pathogenic bacteria suggesting that the active principles may
be useful in the control of plant disease.
