Bushy Dwarf Virus:
Since 1998, this disease has increased in Oregon. Bushy Dwarf (BD)virus causes berries to be crumbly and leaves to developed chlorosis yellowing; although, not all infect plants display this leaf-yellowing symptom. BD can infect both raspberries and marionberries plants, dramatically reducing their fruit production and infecting surrounding plants.

The BD is spread by pollinating insects, because the virus is in the flowers pollen, so they transmitted the virus to other plants. There is no ‘cure” so infected plants must be destroyed.
Replanted with healthy nursery-certified, disease-resistant plants.
Below is a list of Raspberries resistant to BD:
Boyne, *Chilcotin, Citadel, *Comox, Fairview, Restival, Glen Cova, Glen Moy, *Haida, *Heritage, Hilton, Killarney, Malling Admiral, Malling Jewel,Malling Joy, Malling Promise, Nootka, Puyallup, Scepter, Sentinel,Sumner, *Willamette.
Note: *Willamette & Chilcotin raspberries are immune to raspberry bushy dwarf.
While, Haida, Comox and Heritage are moderately resistant.

Raspberry Mosaic:
Raspberry mosaic disease is spread by aphids, symptoms vary but in general they include: stunted canes, delayed leafing out, clusters of shoots coming out from one node, and tip dieback. Leaf symptoms are yellow spots and cupping. This disease affects black raspberries more than red raspberries, but both can be infected. The plant typically dies within two years.
Cultivars resistant to Raspberry Mosaic are:
Canby, Carnival, Chilliwack, Comox, Glen Moy, Glen Prosen, Haida, Malling
Autumn Bliss, Malling Joy, Malling Leo, Nootka, Reveille, Skeena.
Raspberries that are resistant to both diseases are: Haida, Malling Joy, Nootka.
