Situation of grapevine yellows in France in 2001
In France, no new outbreaks of grapevine flavescence dorée phytoplasma (EPPO A2 quarantine pest) appeared in 2001. Previously, a new outbreak had been reported in 2000 in Savoie. Older outbreaks reported in the south west (Bordeaux region) and in the south (Languedoc) have been largely reduced, as a result of chemical control programmes applied against the insect vector.
Grapevine bois noir phytoplasma (=stolbur phytoplasma) is widespread in France, as practically no vine-growing region is free from it. However, the incidence of the disease is very low. Infected plots are scarce and affected plants isolated.
