Cherry Green Ring Mottle Virus (CGRMV) The causal agent of CGRMV was identified about ten years ago in infected cherry trees in the USA. While the disease usually remains latent on sweet cherry and peach, sour cherry and ornamental Prunus species develop leaf yellowing and dark mottles around secondary veins in early June. The fruits are often necrotized. On P. serrulata the disease is very severe with twisting and atrophy of the youngest leaves. In early summer the bark cracks and the young tips die. With rising temperatures in summer plants recover temporarily. About 5 % of cherry and peach cultivars are contaminated with latent CGRMV. It seems to be evenly distributed in the plant and not epidemic. Indexing on P. serrulata and recently developed PCR tests are used for detection of the pathogen.
