Applying a herbicide before plant removal ensures that the root system is killed as well. Blueberry shock, caused by the blueberry shock virus is very similar to blueberry scorch in its symptoms, including a sudden blighting of blossoms and leaves (Photo 5). Transmission occurs when pollinators, especially foraging honeybees, transfer infected pollen to flowers on healthy plants. Virus transmission takes place when bees and other pollinators transfer pollen from infected plants to flowers of healthy plants. However, shock can be differentiated by the scattered distribution of symptomatic bushes among perfectly healthy bushes, the absence of fungal growth on blighted tissues, and a second flush of green leaves on symptomatic branches.

Different strains of the virus exist with the greatest virus diversity identified in British Columbia. Virions are quasi-isometric spheres and 26–29 nm in diameter. Distinguishing between various virus symptoms is difficult in blueberries. In the Pacific Northwest, good yields are possible in well-managed fields after the plants recover. Once a plant is infected, severe yield loss will occur that year. Virus transmission does not occur via contact between plants and is highly unlikely to occur via pruning shears. If you experience any issues with your products or services, please contact ATCC Customer Service at sales@atcc.org. Blueberry shock virus (BlShV) has been identified throughout the Pacific Northwest (Oregon, Washington and British Columbia) but not in any other blueberry growing regions of the world. Plant-to-plant spread occurs when insects — especially foraging honeybees — transfer infected pollen to flowers on healthy plants. Symptoms begin to appear just prior to bloom; affected new tissue appears black and older foliage will turn orange. BlShV was detected by triple-antibody sandwich enzyme-linked immunosorbent assay and reverse-transcription polymerase chain reaction, and isometric virions of 25 to 28 nm were observed in cranberry sap. Blueberry shock virus isolate Berkely segment RNA1 replicase P1 gene, complete cds. During bloom, bushes infected with shock virus will suffer from loss of foliage and blossoms resulting in yield loss. However, the plant then apparently recovers and produces a second flush of leaves. The field should be monitored for sucker development from left-over roots the following spring. Cause The Blueberry shock virus (BlShV), which is pollenborne. The virus can spread rapidly in the field. Blueberry Shock. The rate of spread within a field varies by cultivar. However, in areas where the virus is not known to be present and the infection is localized, removal and destruction of the bushes is recommended.
