Interpretive Summary:

Technical Abstract: There is limited information on the distribution of viruses infecting Rubus spp. in the U.S. or around the world other than where the viruses were first discovered and characterized. A survey for viruses in native and commercial Rubus spp. was initiated in the U.S. in 2017. The results presented here represent the first year of the survey with information from limited previous testing included. The survey is planned to continue through the 2019 growing season. For this survey, assays based on ELISA or variations of PCR were employed to determine the presence of viruses infecting Rubus spp. in major production and nursery areas of the U.S. In the Pacific Northwest, black raspberry necrosis virus (BRNV), raspberry bushy dwarf virus (RBDV), raspberry leaf mottle virus (RLMV), and Raspberry latent virus (RpLV) were most common, with strawberry necrotic shock virus at a low incidence. RBDV and RLMV were the most common in northern Washington and British Columbia, with RBDV and BRNV most common in Oregon. In the upper mid-west, the nematode-borne tomato ringspot virus (ToRSV), blackberry chlorotic ringspot virus (BCRV) and RBDV were detected most frequently with a low level of RLMV. In the mid-Atlantic region, BCRV, RBDV, BRNV, and apple mosaic virus (ApMV) were most common with a low incidence of blackberry yellow vein associated virus (BYVaV), blackberry virus X (BVX), and blackberry virus Y (BVY). With limited sampling from the northeastern U.S., ToRSV and RBDV were detected, but this region along with the southeast U.S. and eastern Canada will be the focus of testing in 2019. In the southeast, BCRV, BVX, BVY, BYVaV, TRSV, beet pseudo yellows virus (BPYV) and blackberry leaf mottle associated virus (BLMaV) were detected. There are other viruses present at low levels in each of the areas, and as such they pose a lower threat to nursery systems or fruit production. The information presented highlights the high risk viruses for nursery production, where efforts are made to control all viruses, and fruit production, where efforts are made to control virus diseases.
