The two grapevine yellows diseases flavescence dorée and bois noir are present in Switzerland. Both spread through contaminated plants (they are graft-transmissible) and/or infectious insect vectors. Whereas bois noir is present in Eastern, as in Western Switzerland, flavescence dorée is confined, so far, in the canton of Ticino. This article presents the situation of the flavescence dorée disease in Switzerland, particularly in regard to bois noir, with which it is often confused. Relevant aspects related to the diagnosis, the control measures and the fight against the disease are also presented.
