Little Cherry Virus 1 (LChV1), Little Cherry Virus 2 (LChV2) and X-disease phytoplasma (‘Candidatus Phytoplasma pruni’) cause small and poor color cherries. Visual symptoms are only seen on mature fruit 1-2 weeks before harvest. Timely scouting, testing and aggressive tree removal are critical to reduce the spread of the disease. Multiple resources are available for scouting and sampling of X-disease and Little Cherry disease during the 2023 season.
