• Symptoms

This physiological disease manifests itself in spring, generally in Mediterranean regions and on growing vegetation. When the drying wind succeeds a rain, this causes a more or less important drying out of the foliage of the vine.

  • Explanatory factors  
    • A tall vine, young and vigorous, with a superficial root system;
    • A rootstock promoting the expression of this disease (161-49C, SO4).
  •  Preventive measures
    • Pinch the end of the twigs to limit evapotranspiration when conditions favorable to folletage appear.
