First report of Citrus bark cracking viroid in Germany
The NPPO of Germany recently informed the EPPO Secretariat of the first detection of Citrus bark cracking viroid (CBCVd - EPPO A2 List) in Germany. The viroid was found in two hop (Humulus lupulus) fields in Bavaria in July 2019 after a report by a grower. Infected plants (150 in the two fields) showed reduced growth. The identity of the pathogen was confirmed by RT-PCR and sequencing. A survey is being performed to determine the extent of the outbreak and official phytosanitary measures will be applied to eradicate the outbreak.
The pest status of Citrus bark cracking viroid in Germany is officially declared as: Transient, only at one location, actionable, under eradication.
