Flavescence Dorée (FD) is a type of grapevine yellow and a serious disease caused by phytoplasma. FD is spread by an insect vector, a leafhopper Scaphoideus titanus, and it
has been shown that it can be transmitted by using infected propagation material, scions and/or cuttings collected from diseased plant during a period of symptom latency. Hot water
treatment of propagation material could prevent from this danger.
