Cabbage is one of the most popular winter cruciferous vegetables grown in India. It is mostly cultivated in cool places and hence, the crop is mostly affected by Xanthomonas campestris pv. campestris (Xcc) (Pammel) causes black rot disease worldwide. Increased usage of different chemicals based products to control these pathogens have resulted in problems like residual effect of chemicals in agri-based products and also increased resistance for chemicals in target pathogens and environmental pollution. The crude extracts of some well-known botanicals, biocontrol agents and organic amendments are used to control some of the plant pathogens.  The results of botanicals the leaf extract of Datura stramonium (10%) was maximum inhibition and minimum inhibition of Ocimum basilicum were recorded. Whereas, the biocontrol agents of Streptomyces spp and Trichoderma viride showed maximum inhibition zone were effective against the growth of Xcc.
