Summary: The objectives of this project were: Objective 1: Determine areas with sweet cherry trees expressing symptoms associated with Little Cherry Disease (caused by the pathogens Little cherry viruses 1 & 2 and/or X-Disease phytoplasma) in Oregon’s Mid-Columbia region. Objective 2: Conduct regional Mid-Columbia survey for Cherry leaf roll virus and the Cherry leaf roll virus complex with Prune dwarf virus and Prunus necrotic ringspot virus on sweet cherry. Objective 3: Survey Mid-Columbia sweet cherry orchards for nematode-transmitted viruses (such as Cherry rasp leaf virus, Tobacco ringspot virus, and Tomato ringspot virus) and their vectors. Objective 4: Investigate spread and diversity of Tomato ringspot virus isolates from cherry in known-infected areas.
