The causal agent of Ascochyta blight in hairy vetch is the highly specialized fungus Ascochyta viciae-villosae Ondřej. The pathogen exhibits high specificity to this plant species, while other members of the genus Ascochyta that affect other legumes do not cause disease symptoms on hairy vetch.
The disease manifests as the formation of necrotic spots on leaves, stems, petioles, and tendrils of the plant. Specific resistance genes for this pathogen have not been identified in this crop; therefore, breeding efforts are focused on selecting phytocenotically stable biotypes with complex resistance.
