The Potato Corky Ringspot Pathogen, Tobacco rattle virus, Occurs in Native Habitats in Minnesota

B. E. Lockhart and S. L. Mason

October 2011

Brief

When corky ringspot of potato, caused by Tobacco rattle virus, was first reported in Minnesota in 2008, it was thought that TRV did not occur naturally in Minnesota. Results reported here indicate that TRV occurs in Minnesota in areas with no known history of cultivation to potatoes or other crops, that these TRV isolates are variable, and that some are similar to virus isolated from potato with corky ringspot symptoms. These data suggest that corky ringspot incidence in Minnesota is due to the presence of endemic rather than introduced sources of TRV.
