Abstract Apricot (Prunus armeniaca) is important in the economy of Turkey. Chondrostereum purpureum causing silvering was observed in apricot growing areas in Malatya, Turkey. The characteristic symptom of the diseased tree was silvering of leaves resulting from fungal toxin. The disease incidence was found to be 2–15% in surveyed areas. The pathogenicity test was undertaken on apricot trees in a nursery, and disease incidence was found to be 22% after inoculation.

Keywords Chondrostereum purpureum; silver leaf; disease incidence; apricot
