Update on the situation of Ralstonia pseudosolanacearum in Germany
In Germany, Ralstonia pseudosolanacearum (EPPO A2 List) was first reported in 2021 in a research institute in Hesse on symptomatic ginger (Zingiber officinale) and tomato plants (Solanum lycopersicum) in a greenhouse (RS 2021/040). Official eradication measures were taken.
In June 2022, symptoms were observed again on ginger plants in the same location. Both ginger and cucumber plants (Cucumis sativum) which were grown in the same greenhouse tested positive for R. pseudosolanacearum. The source of the infestation is not known, nor whether it is a carry-over from the previous year's occurrence or a new introduction. Official eradication measures are applied, and a survey will be carried out for at least 3 years.
The pest status of Ralstonia pseudosolanacearum in Germany is officially declared as: Present, only in one location, under eradication.
