Understanding the control strategies effective against the esca leaf stripe symptom: the edge hypothesis
New and OpinionA peculiar symptom that may develop in grapevines affected by wood pathogens
involved in the esca complex of diseases is the leaf stripe symptom, which also
gives the name to the Grapevine Leaf Stripe Disease. Multiple studies have revealed
strong links between fungal presence, wood symptomatology and expression of the
leaf stripe symptom. However, numerous other factors have been shown to play roles
in symptom onset, incidence, severity and yearly fluctuation of this disease. While the
factors triggering the leaf stripe symptom are still under investigation, three control
strategies have been proven effective for substantially reducing its expression, namely
trunk surgery, and applications of sodium arsenite or a fertilizer mixture. These control
strategies are examined here, including their (putative or confirmed) modes of action,
and how they may influence the leaf stripe symptom development. In this article, we
also propose the ‘edge’ hypothesis to tentatively explain symptoms onset, keeping in
consideration past knowledge and recent advances in the understanding of the esca
leaf stripe symptom. Ultimately, it is our intention to offer food-for-thought and stimulate
debate within the phytopathological communityinfo:eu-repo/semantics/publishedVersio
