Abstract:
Cabbage (Brassica family) is a vital winter vegetable, globally valued for its nutritional content and health benefits. Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is a prevalent and devastating disease affecting cabbage, leading to substantial yield losses. This study aimed to evaluate the inhibitory effect of eleven different fungicides and antibiotics against Xcc under in-vitro conditions using an agar well method with three different concentrations. Results indicated that all tested fungicides and antibiotics significantly reduced Xcc growth compared to the control. The maximum growth inhibition was recorded in streptomycin sulphate 90% + tetracycline hydrochloride 10% SP mixed with copper oxychloride 50% WP at all three concentrations tested. Another effective treatment was the combination of Streptomycin sulphate 90% + tetracycline hydrochloride 10% & Bordeaux mixture 1%. These findings offer valuable insights for farmers and researchers seeking to combat this destructive disease in cabbage cultivation.
