Soon after the discovery of Tobacco streak virus (TSV) in cranberry, Blueberry shock virus (BlShV) was also associated with cranberry scarring symptoms in Wisconsin and Massachusetts. BlShV and TSV cause identical scarring symptoms on cranberry and cannot be distinguished in the field. Scarred berries turn red prematurely, making it relatively easy to identify hotspots of disease in the field, especially during the early stages of fruit development (mid- to late July). Unlike TSV, which affects many crops, BlShV is known to infect only cultivated blueberry and cranberry. This fact sheet offers a succinct list of symptoms and recommendations for handling BlShV (4 pages; 2017).
