The European mountain ash ringspot associated virus (EMARaV) is a pathogen that infects mountain ash trees (Sorbus aucuparia). The pathogen attacks the leaves of its hosts where it causes mottling and discoloration. In extreme cases the productivity of the tree can be affected, which can result in its gradual decline.
