It's a golden jaundice Grapevine flavescence dorée phytoplasma one of the most dangerous vines in grapevine. As a result of the infection, the yield of vineyards can be reduced by 20 to 50 percent and the number of diseased plants may increase by one to ten times a year.
There is currently no suitable plant protection product available to combat this disease, but its spread may be stopped by American grapes (Scaphoideus titanus), as the pathogen that grows in the insect body moves into healthy plants by planting the plants. If control is not effective enough, 80 to 100 percent of bones can be infected with phytoplasma, and sensitive varieties may die within a few years.
