Flavescence dorée (FD) and other types of grapevine yellows are serious diseases of grapevines caused by phytoplasmas. FD is spread by a leafhopper species, and it has been shown to be transmitted by using infected cuttings. Data are presented for the effective use of hot‐water treatment to eliminate FD. Immersion time has to be increased logarithmically when temperature is reduced linearly. The effective treatments range from 10 h at 40°C to 10 min at 55°C. The eggs of the leafhopper vector of FD, Scaphoideus titanus , are also killed by immersion at 50°C for 45 minutes. This temperature/time combination is recommended for treating dormant cuttings of grapevines for the elimination of FD.
