Eutypa canker and dieback of almonds was first recorded in commercial plantations in Greece in mid‐1980 and confirmed as due to the ascomycetous fungus Eutypa lata. The disease manifests itself by the formation of cankers at the point of the junction of the branches and the trunk and is associated with pruning wounds made by the growers in order to confront the‘non‐infectious bud failure’disorder or to remove unwanted limbs close to the crotch. Pathogenicity tests made on young trees of cv. Texas with different isolates originated from grapevine, almond, apricot and pear showed significant differences in virulence. Pathogenicity tests carried out on 20 different almond cultivars gave a significant indication of the existence of tolerant and susceptible cultivars.
