The aim of this study was to investigate the effect of esca disease on bud break of grapevine in relation to different rootstock combinations. For this purpose under field conditions observations of flower bud phenological stages were carried out on three widespread grapevine cultivars 'Cabernet Sauvignon', 'Sangiovese' and 'Trebbiano toscano'. Further phenological observations were recorded under forcing conditions using 'Cabernet Sauvignon' as the most susceptible to esca disease. Each cultivar was grafted on K5BB, 1103P and own rooted. The plants were infected by esca due to the natural presence of fungi in the vineyard. Results showed that esca disease significantly delayed bud break of symptomatic vines for several years. Grapevines on different rootstocks showed different bud break changes, in particular those on K5BB were the most susceptible to esca.
