Xylella fastidiosa bacterium detected in Luxembourg vineyards

The bacterium Xylella fastidiosa, known as the fire bacterium, has been detected in vineyards in the Luxembourg municipalities of Mertert and Grevenmacher. This discovery has led to the establishment of buffer zones that extend into the Trier-Saarburg district of Rhineland-Palatinate, Germany.

Maximilian Hendgen, managing director of the Mosel Winegrowers Association, expressed significant concern among vintners, noting that the pathogen is a new threat for which there is little experience. Once infected, vines cannot be cured and must be removed. The bacterium is typically spread by insects that feed on plant sap.

Luxembourg has already completed clearing operations in the three primary infection zones, with additional removal of potential host plants ongoing. Authorities in Trier have announced that restrictive measures for the buffer zones will be detailed in an official general decree expected to take effect early next week.
