Managing Bacterial Ring Rot of Potato
June 1, 2022
Bacterial ring rot, caused by the bacterium Clavibacter sepedonicus, is one of the most destructive potato diseases in the world. Because losses due to stored, decaying potatoes can be substantial, seed growers risk losing certification eligibility. Contamination cleanup costs add more to the burden, so it’s crucial to know how to minimize the risks.
Integrating data gleaned from a two-year dual-state study (in North Dakota and Idaho) conducted by UI Extension and USDA researchers, this bulletin discusses the symptoms and signs of an outbreak, the pathogen’s disease cycle, prevention management practices and tips if the worst occurs. Full-color photography helps growers to more accurately identify potentially afflicted tubers and a handy resource guide provides further assistance, including webinars.
