The wine industry plays important social and economic roles in the region of canton Vaud in Switzerland. Since 2015, “flavescence
dorée” (FD), a disease associated with a phloem-limited bacterium, has been present in the vineyards and represents a major
threat to viticulture. The disease is propagated epidemically by its principal vector, the leafhopperScaphoideus titanus. The
“flavescence dorée” phytoplasma is a quarantine pest, and is therefore under a national surveillance program. Control measures
such as roguing infected stocks and insecticide treatments must be applied in affected perimeters. Regional phytosanitary
services are responsible to organize the inspection of these areas. Each year, a systematic survey ofS. titanus populations and
symptomatic grapevines is conducted to assess that the actions are properly implemented. Here, a few examples from
representative outbreaks are presented. The compulsory measures are efficient and, as expected, the pathway to disease
eradication strongly depends on the initial severity of the outbreak. An adapted management strategy, based on individual risk
analysis of each affected perimeter, to reduce the surface treated with insecticides was proposed.
