Situation of grapevine flavescence dorée in Cataluña (Spain)
In October 1996, grapevine flavescence dorée phytoplasma (EPPO A2 quarantine pest) was reported for the first time in Spain in Cataluña (Alt Empordá), near the French border (see EPPO RS 97/113). The two first foci found in the municipalities of Agullana and Sant Climent de Sescebes were destroyed during winter 1996/1997. Later, four foci were found near the initial point of discovery, and two other foci of limited extent were also observed at a slightly greater distance (in the municipalities of Espolla and Cantallops). However, the disease is still limited to Alt Empordá. A survey was also carried out to determine the distribution of the vector, Scaphoideus titanus, in Cataluña. It is present in Alt Empordá where the disease occurs and also in the western part of Cataluña, but many areas are still free from it. Eradication measures have been taken and include: strict control of grapevine planting material, destruction of affected grapevines (and of abandoned vineyards), compulsory control of Scaphoideus titanus.
