Summary: The objectives of this project were: Develop a strategy to control the rapid decline of cherry trees associated with Cherry leaf roll nepovirus. a) Determine transmission mechanisms for Cherry leaf roll virus in orchards of the Pacific Northwest and conditions affecting the disease development associated with this virus. b) Initiate small-scale trial to determine symptoms of Cherry leaf roll virus on new and promising cherry cultivars. Determine the biology of an emerging and very severe virus disease of cherries in the Columbia River Valley. a) Determine sources of an emerging virus disease in Central Washington and the impact of these diseases on cherry varieties and rootstocks. b) Develop diagnostic capabilities suitable for monitoring little cherry viruses in orchards of the northwest.
