Interpretive Summary: Roses are woody flowering plants widely used for ornamental purposes. A rose plant obtained from a Minnesota public garden was identified with rose rosette disease symptoms and was confirmed as infected with Rose rosette virus (RRV) by laboratory analyses. This is the first report of RRV infecting roses in Minnesota. This information will be useful to plant diagnosticians and regulatory agencies, as well as the ornamental and the landscape industries.

Technical Abstract: A Rosa hybrida plant was identified with rose rosette disease symptoms and was positive for Rose rosette virus (RRV) by reverse transcription PCR. It is important to monitor routinely roses for RRV symptoms and to test and rogue symptomatic plants. This is the first report of RRV infecting roses in Minnesota.
