Flavescence dorée (FD), a quarantine phytoplasma disease, appeared in Switzerland in 2004 in Ticinese vineyards, where it remains confined. Its spread throughout the territory has been constant. Overall, 37.4 % of all samples received were tested FD-positive. All told, 188 plots belonging to 161 producers were infected for the past ten years. In 13 % of the plots, FD was consistently diagnosed during a time interval of between four and ten years, despite its mandatory control. Ten years with FD have highlighted the complexity of the system and the need for a better understanding of variety sensitivity to FD, the potential role of alternative vectors and host plants, the ecological relationships involved and how the environment influences the different components of the system. This ten years experience underlines that a long-term coexistence is to be managed with this disease.
