Cherry buckskin disease, also called X-disease, is a major cause of
cherry decline, the cause of serious losses of sweet cherry trees in areas of
California.
Diseased trees produce pebbly, leathery-skinned, pale fruit. On
Mahaleb rootstocks, trees may also suddenly wilt and
collapse above the graft union. Buckskin is caused by a phytoplasma organism
that is found in phloem cells of infected trees.
The disease is most often spread by leafhoppers, which acquire the
disease organism when feeding on diseased cherries or other plants that host
the disease organism. Remove diseased cherry trees and manage leafhopper
populations (see sections on MOUNTAIN LEAFHOPPER and CHERRY LEAFHOPPER)
to limit the spread of cherry buckskin.
