Summary

​This presentation will help consultants, growers, and other practitioners in U.S. potato-producing areas implement proper sanitation and disinfectant procedures for bacterial ring rot, a zero-tolerance disease in the seed potato industry. Periodic outbreaks of this disease require vigilant testing and sanitation to prevent and manage additional spread and infection. This presentation explains survival of Clavibacter michiganensis subsp. sepedonicus bacteria, proper disinfection procedures to prevent ring rot, suggestions for cleaning facilities and equipment contaminated by ring rot, and characteristics of frequently used disinfectants. By the end of this presentation, practitioners and potato growers should understand proper sanitation and disinfection procedures to reduce the risk of bacterial ring rot in potato operations and farms.
