Antecedentes

El oídio de la vid es una de las principales enfermedades fúngicas del cultivo de vid en todo el mundo.

Aunque por lo general no causa directamente la muerte de la planta, las infecciones intensas pueden provocar grandes pérdidas de rendimiento, e incluso niveles bajos de la enfermedad pueden afectar negativamente la calidad del vino.
