Fungal species involved in Esca cause the formation of grapevine wood necroses. It results in the deterioration of vascular network transport capacity and the disturbance of the physiological processes, leading to gradual or sudden grapevine death. Herein, for two consecutive growing seasons, a detailed analysis of the structural (wood necrosis and leaf discoloration) and physiological parameters related to the water use of healthy and esca-symptomatic grapevines was conducted.

- Esca is caused by various fungal pathogens that damage grapevine wood tissues, leading to physiological changes and potential plant death.
- Significant decreases in sap flow density and whole-plant transpiration were observed in Esca-infected grapevines a week prior to visible symptoms, indicating early signs of water transport disruption.
- The study highlights the correlation between necrotic wood in symptomatic vines and reduced hydraulic capacity, suggesting that physiological monitoring can enhance disease detection and management strategies.
