First report of Ralstonia pseudosolanacearum in Hungary
The NPPO of Hungary recently informed the EPPO Secretariat of the first finding of Ralstonia pseudosolanacearum (EPPO A2 List) on its territory. Following the recent reports of this bacterium in the Netherlands and in Germany (EPPO RS 2021/140, RS 2021/179, RS 2022/195), the NPPO of Hungary decided to test water samples contaminated with Ralstonia solanacearum species complex with a specific test which can distinguish the different Ralstonia species of the species complex, as described in EU Regulation 2022/1193. The tests were carried out by the National Reference Laboratory for Plant Health in September 2022. Samples from three counties (Hajdú-Bihar in Eastern Hungary, Jász-Nagykun-Szolnok in Central Hungary, and Zala in South-western Hungary) were positive for Ralstonia pseudosolanacearum. Further tests will be conducted to clarify the origin of the contamination.
The pest status of Ralstonia pseudosolanacearum in Hungary is officially declared as: Present.
