Eradication of Grapevine flavescence dorée phytoplasma from Germany
In 2014, Grapevine flavescence dorée phytoplasma (EPPO A2 List) was detected for the first time in Germany on grapevine (Vitis vinifera cv. Chardonnay/SO4) in Rheinland-Pfalz (EPPO RS 2014/202). One plant was found to be infected in a lot of 4 400 grafted plants. The rootstocks originated from Italy. The infested plant was destroyed and 600 plants of the lot were treated with hot water. The remaining plants were replanted and visually inspected in July and September 2015. No suspect symptoms were observed. In addition, it is noted that the phytoplasma was not detected again in the survey conducted in Rheinland-Pfalz and that the vector, Scaphoideus titanus, does not occur in Germany. The NPPO of Germany considers that the disease has been successfully eradicated.
The pest status of Grapevine flavescence dorée phytoplasma in Germany is officially declared as: Absent, eradicated.
