Gnomonia fructicola

Gnomonia fructicola is a fungal plant pathogen on strawberries causing leaf spot disease. It can overwinter on leaves and fruits of Fragaria spp. (Rosaceae), occasionally pathogenic on fruits causing strawberry stem-end rot. The causal organism has often been referred to as Gnomonia comari, now considered Gnomoniopsis comari. It occurs in Canada (British Columbia), Europe (Belgium, France) and U.S.A. (MD, NY).
