Interpretive Summary: Technical Abstract: Rubus stunt is a severe disease that naturally infects only plants in the genus Rubus, and no immune Rubus germplasm has been reported. Apium, Chrysanthemum, Fragaria, and Trifolium species have been used as experimental hosts for Rubus stunt phytoplasma. The disease occurs in wild and cultivated Rubus in Europe, the Soviet Union, and the Middle East. Crop-threatening epidemics have occurred in some areas of Europe and the Soviet Union. Rubus stunt is not known to occur in North America, but Macropsis fuscula Zett., the major leafhopper vector of Rubus stunt in Europe, has become well established in western North America in wild blackberry, especially in R. armeniacus (Himalaya blackberry). At present, importation of vegetative Rubus plant material into the United States from Europe is restricted, partly because of the threat posed to the U.S. Rubus industry by this disease. Although the disease occurs only in Europe, it poses a threat to North American Rubus crops. This disease in most cases is caused by the phytoplasma, Rubus stunt, a member of the Elm Yellows (16SrV-E) group, with one report of X-Disease (16SrIII) group reported from Rubus in the United Kingdom. and a second report of a member of the (16SrIII) group from black raspberry in Oregon. |
