Bacterial Blight, caused by Xanthomonas citri subsp. malvacearum (Xcm) has been periodically a damaging disease throughout the Cotton Belt. Damage has been most serious when a region plants a large portion of susceptible cultivars and weather events combine to favor epidemic development. The bacteria can survive in seed, even acid-delinted seed. In 2011 an outbreak of Bacterial Blight started in Northeastern Arkansas and spread throughout the Central Delta. The outbreak has never fully subsided. In 2015 Bacterial Bight was problematic in Georgia, Mississippi, and Texas, among other states. A research review was held in April 2016 at St. Louis, Missouri by Cotton Incorporated and the Donald Danforth Plant Science Center to bring together our knowledge of the pathogen and the disease, and to propose a national research program to manage Bacterial Blight.
