Blueberry scorch virus (BBScV) is a plant disease of
blueberries (Vaccinium spp.) and cranberries (V. macrocarpon) as well as other
Vaccinium species.
Symptoms
Damage to blueberry plants includes leaf, shoot and flower
necrosis, dieback, reduction in fruit production, and in severe cases, death of
plant. Cranberries are symptomless. Symptoms can easily be confused with other
pest, disease, cultural or environmental problems. If BBScV is suspected, the
only reliable method to verify its presence is through laboratory testing. Once
infected, plants will permanently carry the virus. BBScV is transmitted by
aphids, but can also be spread by propagation via an infected mother plant.
