Candidatus Phytoplasma vitis 16SrV-D
Flavescence doree (Candidatus Phytoplasma vitis 16SrV-D) is a phytoplasm of grapevine. It is a native of North America and was first detected in Europe.
Symptoms of flavescence doree are similar to other grapevine yellowing diseases. Yellowed and curled leaves, drooping shoots, and lack of grape production are all symptoms. This disease can spread quickly throughout a grape vineyard and threatens wine production in several areas of Europe, particularly France.
