The use of tested virus-free plant material especially when using S. aucuparia as rootstock in nursery propagated species of the Maloidea-subfamily is highly recommended. Reliable diagnosis of EMARaV can be done by molecular tools such as virus-specific RT-PCR or RT-PCR using genus-specific primers in combination with Sanger-sequencing (Rehanek et al. 2022). Commercial serological tests are not available yet. EMARaV-infected host plants in urban environments should be cultivated under optimal environmental conditions to keep their vitality. If that is not possible the infected tree has eventually to be removed, if it shows ongoing decline symptoms. This decision depends on the trees function and epidemiological risk to infect further host species.
