Carraro L, Loi N, Kuszala C, Clair D, Boudon-Padieu E, Refatti E, 1994. Flavescence dorée (FD) is a quarantine disease with huge consequences on the vine-growing economy, including yield loss and degraded grape quality. Leaves turn yellow or red depending on the cultivar.

'Universal' assays use primers constructed from conserved nucleotide sequences in phytoplasma ribosomal DNA (16S rDNA and intergenic spacer) (see review by Seemüller et al., 1998). In France, control of flavescence dorée is subject to several legislative directives. Directives from the local authorities regulate the mandatory control of flavescence dorée and its vector for particular areas where flavescence dorée is present. Special issue: Flavescence dorée.

Elle doit être réalisée collectivement pour être efficace et fait appel à plusieurs méthodes complémentaires : Lorsque ces mesures sont correctement appliquées, la flavescence dorée ne progresse pas et le vignoble peut être assaini progressivement. These PCR assays are especially useful for the survey of grapevine yellows (Daire et al., 1997b), and also for the identification of still unknown grapevine yellows agents and the identification of insect vectors.

Two kinds of primers may be used, either for specific assays to identify flavescence dorée phytoplasma or for 'universal' detection assays that allow the detection of any phytoplasma (Seemüller et al., 1998). Flavescence dorée first appeared in 1949 in the Armagnac region of south west France. Inoculation pressure may be reduced by the destruction of sources of infection consisting of infected vines.
