Interpretive Summary:

Technical Abstract: There are several important virus diseases of raspberry and black raspberry in the Pacific Northwest. Pollen-borne viruses include Raspberry bushy dwarf virus and Strawberry necrotic shock virus (aka Tobacco streak virus –Rubus isolate or Black raspberry latent virus). Strawberry necrotic shock virus is common but symptomless in field-run 'Munger' and 'Boysenberry'. Strawberry necrotic shock virus will spread from infected 'Boysenberry' to immediately adjoining red raspberry rows, where it causes no obvious symptoms or crop loss. This virus is transmitted by thrips in strawberry and there is some evidence it can be transmitted by thrips Rubus spp. since there can be low levels of transmission in plants that are not flowering. It can be detected serologically or by RT-PCR. Crumbly fruit is characterized by the abortion of many drupelets which causes the fruit to crumble at harvest, resulting in significant reductions of yield and fruit quality. Reduced plant growth and leaf patterns may also occur. Ringspot symptoms vary from mottled, chlorotic, mosaic leaves to leaf curling and ring spotting. Infected plants often show no symptoms but have low vigor and yield. In the case of Tomato ringspot virus, young leaves on primocanes often show a chevron pattern and ringspot early in the season.
