摘　　要：Grapevine trunk diseases (GTDs) are currently one of the most important problems for grapevine plant and wine industry, causing important economic cost in Castilla-La Mancha, Spain. Traditionally, GTDs were associated with diseases present in mature grapevines, however in recent years the incidence of young vine decline has been increasing. In this work, from 2009 to 2016, 250 young grapevine plants have been analysed by fungal isolation and characterization. In addition, during 2017, 32 mature plants showing decline symptoms were analysed. Both kinds of plants were analysed in order to identify the main fungal trunk pathogens present in Castilla-La Mancha region. As a result, it was possible to isolate species associated with black-foot disease (Cylindrocarpon-like anamorphs), esca and Petri disease (Phaeomoniella chlamydospora and Phaeoacremonium spp.), and Botryosphaeria dieback. All these pathogens were isolated from young and mature plants, this fact could suggest a common origin. The lack of effective control measures for these diseases makes it necessary to implement an integrated disease management strategy that provides an efficient approach to reduce infections in nurseries and get better results in infected vineyards.
