An Austrian/French research report on the effect of heat treatments on the survival of E. amylovora was presented by Keck et al. Incubation in a humid atmosphere or hot water at 45° C for 3 h eliminated the bacteria without damaging the buds. It was concluded that thermotherapy can be used under certain conditions to eliminate E. amylovora from budwood of apple and pears.
