Black rot disease of crucifers is one of the economically important diseases of cabbage and cauliflower in Nepal. The causal organism, Xanthomonas campestris pv. campestris is seed-borne  in nature. Experiment has been conducted in the laboratory and screenhouse to find out the role of seed-borne infection in the development of disease in seed and seedling, and to find out the seed dresser for its control. Among the tested varieties, Copenhagen market showed the highest seed and seedling infection.The relationship between seed and seedling infection was found positive (r = 0.87 1, P= 0.08). Among the treatments used as seed soaking 0.2 % of Copper sulphate and Zinc sulphate were found statistically superior than 0.2% urea and Fluorescing Pseudomonas.
