Chinese cabbage (Brassica campestris L. var pekinensis) is an Asian vegetable appreciated in all continents for its nutritional value and medicinal properties. Reports from farmers across the country have shown that there are economic losses in this crop apparently caused by bacterial diseases, one of which is bacterial wilt, which decreases the time of viability of the product also its continuity in the market and therefore, non-use by the consumer. Growers in Cogua, Colombia reported an 80% loss in production due to this disease. The main symptom is the presence of moist lesions and wilting on the outer edges of the leaves.
The objective of this project was the identification of potential microbiological pathogens of bacterial wilt in a Chinese cabbage crop in Cogua, Colombia. The methodology included the analysis of microorganisms in healthy and diseased plants, isolation of bacteria in the vascular lesions, the development of pathogenicity and phenotypic identification of the pathogen. The results concluded that the pathogen that caused bacterial wilt on crops of Chinese cabbage in Cogua, Colombia was Xanthomonas axonopodis. The identification of pathogens in plants of economic interest can take more effective measures relating to good agricultural practices to manage diseases in plants and reduce production losses.
