Sloe (Prunus spinosa), European bird cherry (P. padus) and black cherry (P. serotina) are natural hosts of cherry ringspot viruses (prune dwarf and Prunus necrotic ring spot) in the GDR. However, no virus infestation was found in choke cherry (P. virginiana). Some 8.8% of sloes, 2.3% of bird cherries and 1.1% of black cherries were infected. Of 21 isolates from sloes 4 belonged to Prunus necrotic ring spot and 14 to prune dwarf, with 3 mixed infections. Only Prunus necrotic ringspot was isolated from bird cherries. Seed transmissiosion could not be demonstrated in these 2 Prunus spp.
