Publication Type: Abstract Only Publication Acceptance Date: 6/23/2022 Publication Date: N/A Citation: N/A Interpretive Summary: Technical Abstract: Potato mop-top virus (PMTV) is a pathogen of economic concern for potato growers in the Northwest U.S. PMTV is vectored to potato by Spongospora subterranea, a fungal pathogen that causes root galling and powdery scab on tuber surfaces (Figure 1A, B). PMTV causes internal tuber necrosis (Figure 1C, D). Visually, PMTV symptoms are indistinguishable from Tobacco rattle virus (TRV). Between 2016 and 2022, tubers from the Washington Seed Lot Trial were tested for the presence of both tuber necrotic viruses to determine the prevalence of PMTV and TRV in seed. |
