New findings of Grapevine flavescence dorée phytoplasma in Germany
In Germany, Grapevine flavescence dorée phytoplasma (EPPO A2 List) was found in one plant of grapevine (Vitis vinifera) in Rheinland-Pfalz in 2020 (EPPO RS 2021/040) and eradicated (RS 2022/172).
At the end of 2025, as part of national surveys, Grapevine flavescence dorée phytoplasma was detected again in grapevine plants (Vitis vinifera) in three locations in Baden-Württemberg:
- Two in different vine nurseries: as no vectors are present in these areas, it is assumed that the infestations originate from the initial planting material. Tracing investigations are ongoing. All plants of either the same rootstock or scion were destroyed or underwent hot water treatment.
- One in young grapevine plants planted in a vineyard in 2024. The vineyard is located in the infested area for Scaphoideus titanus (RS 2024/190). Official measures are applied.
The pest status of Grapevine flavescence dorée phytoplasma in Germany is officially declared as: Present, at low prevalence, in specific parts of the Member State, where host crop(s) are grown, under eradication.
