Blueberry shock virus

Blueberry shock virus (BlShV) is an Ilarvirus belonging to the Bromoviridae family. The Bromoviridae family contains single-stranded, positive-sense RNA viruses. Virus particles are icosahedral and 30 nm in diameter. Blueberry shock virus causes shock of blueberries in Oregon, Washington, and British Columbia. It gets its name because plants are shocked by the initial infection, meaning the flowers and foliage blight and wilt in the early spring, right when the plant is in full bloom. BIShV was first discovered in a blueberry field containing highbush blueberry (Vaccinium corymbosum L.) in Washington in 1991. It continued to spread to Oregon, Washington and British Columbia since that time. In 2009, the disease was found in a western Michigan field, and may be preset in Pennsylvania as of 2011. Since its discovery, eradication is in progress to eliminate the disease and reduce loss of yield from it.
