First report of Elderberry symptomless virus and Elderberry latent virus in Austria
The NPPO of Austria recently informed the EPPO Secretariat of the first findings of Elderberry symptomless virus (Carlavirus - syn. Elderberry virus A) and Elderberry latent virus (tentative Carmovirus) on Sambucus sp. in Steiermark. Samples of cultivated Sambucus trees were collected and sent to the NPPO laboratory for diagnosis. Electron microscopy revealed the presence of the above viruses. The NPPO ordered the uprooting of the infested trees and a treatment against aphids. In addition, it was prohibited to replant Sambucus trees in the infected area.
The pest status of Elderberry symptomless virus and Elderberry latent virus in Austria is officially declared as: Local outbreaks; transient: actionable, under eradication.
