A pathological diagnosis was made of an Andean blackberry crop (Rubus glaucus Bentham) in the rural area of Pascote, in the municipality of Gutiérrez, Cundinamarca, Colombia. Samples were taken from blackberry leaves, stems, flowers, fruit and roots; they were processed and identified in the Universidad de Los Llanos’ plant pathology laboratory. Pathogen/disease symptom incidence was evaluated in the field. Four fungal pathogens were found and identified: Colletotrichum gloesporoides (Penz.) Penz (anthracnose), 40% incidence, Peronospora sparsa Berk (downy mildew), 20% incidence, Oidium sp. (powdery mildew), 12.5% incidence, and Botrytis cinerea Perms (gray mold disease), 7.5% incidence.
