Among all causes of grapevine decline, Grapevine Trunk Diseases (GTDs) are major concerns for grape growers. This paper reviews knowledge and proposes hypotheses on two GTDs, esca Botryosphaeria dieback, assembles a conceptual model. The objective was to collect information into sequence, from nursery propagation processes, through foliar symptom expression, plant death in mature vineyards. Pathogen infection colonization steps woody vine tissues, the that have been formulated explain outburst symptoms, reported discussed. Factors could aggravate or repress GTD symptoms incidence expansion also addressed. Vine physiology pathology together expand understanding these diseases. Knowledge need validation summarized, model is proposed occurrence influencing factors. be useful cope with complexity as starting point research unravel gaps suggest new disease management strategies.
