Situation of flavescence dorée and its vector Scaphoideus titanus in Switzerland
In Switzerland, Grapevine flavescence dorée phytoplasma (EPPO A2 List) remains confined to the canton of Ticino where it was first found in 2004. In 2007, new outbreaks were detected in Ticino, in the Malcantone area (Magliaso and Madonna del Piano). The insect vector of the disease, Scaphoideus titanus, occurs in Ticino, as well as in a few vineyards in the cantons of Geneva and Vaud. In 2007, it was observed for the first time in the Valais canton (Port-Valais, Vionnaz) and in new areas in Vaud (Morges and its vicinity). Compulsory control measures against the vector continue to be applied in Switzerland to prevent the spread of flavescence dorée.
The situation of Grapevine flavescence dorée phytoplasma in Switzerland can be described as follows: Present, few outbreaks found in the canton of Ticino, under official control.
