Overview

Demonstrates the effectiveness of foliar applications in reducing symptoms of Esca disease in vineyards, indicating potential for improved yields.

Key Points

To evaluate the effectiveness of a foliar mixture on reducing Esca disease symptoms and improving grape yield.
Conducted treatments with a mixture of calcium, magnesium, and seaweed in four vineyards.
Applied the mixture at 10-day intervals from BBCH stage 19 to stage 83.
Assessed the impact on both chronic and acute forms of Esca disease.
Evaluated vine yield and quality under different climatic conditions.
Achieved a reduction of approximately 50% to 60% in chronic leaf symptoms in 2022.
Treated vines exhibited improved yield and quality under optimal growth conditions in 2022.
In 2023, the effects on symptoms were smaller, with no yield improvement observed due to heavy rains.
Significant reduction in vine mortality due to the apoplexy form was confirmed in 2024.
