Blueberry scorch virus (BISV) is a plant disease of blueberries (Vaccinium spp.) and cranberries (V. macrocarpon) as well as other Vaccinium species. 


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 BISV suspected, the only reliable method to verify its presence is through laboratory testing. Once infected, plants will permanently carry the virus. BISV is transmitted by aphids, but can also be spr​ead by propagation via an infected mother plant.
