Improving the Control of Flavescence Dorée: Latest Insights and Future Directions
Presented by
Description
Flavescence dorée is a grapevine disease caused by a phytoplasma and transmitted by an insect vector—a leafhopper. Affected vines show reduced yields and, in most cases, eventually die. Highly contagious and incurable, the disease is prevalent in vineyards across Europe. Its emergence in the Champagne region in 2021, followed by its rapid spread, has become a major concern and a rallying point for stakeholders in the wine industry.
The presentation will begin with a brief introduction to the biology of Flavescence dorée and how it differs from the disease known as Bois noir. It will then outline the impact of the disease in Europe and the Champagne region, as well as the measures that must be implemented to improve its control.
Next, the presentation will outline the latest knowledge regarding the ecological cycle of Flavescence dorée, the associated risk factors, and the dynamics of both the disease and its insect vector.
Finally, a concluding section will detail several promising avenues for better controlling Flavescence dorée, including the evaluation of more effective and earlier detection methods, the search for grape varieties with lower susceptibility, and trials of alternatives to insecticides for managing the leafhopper vector.
