​Bacterial ring rot of potato is one of the most feared tuber-borne diseases of potato. On an annual basis, economic losses due to ring rot are low, but the constant threat of severe and devastating losses warrants the continued vigilance of the potato industry. Although the bacterium that causes ring rot is primarily disseminated by seed potatoes, the bacterium is also capable of surviving outside its host for extended periods. Disease management depends an integrated approach using high-quality seed, modern pathogen detection technologies, and sanitation.
