El Instituto vasco de Investigación y Desarrollo Agrario, Neiker-Tecnalia, ha desarrollado un nuevo método de detección temprana de las enfermedades mildiu, oidio y botritis, habituales en las vides. La nueva metodología, basada en técnicas de biología molecular, permite detectar la enfermedad antes de que aparezcan los síntomas en la planta. De este modo se puede llevar a cabo el tratamiento rápido de las parcelas o áreas afectadas y evitar así que la patología se propague en el conjunto del viñedo, con lo que se logra disminuir la presión infectiva. Por otra parte, el centro tecnológico ha estudiado la evolución de la infección del patógeno Plasmopara viticola –causante del mildiu- sobre cuatro variedades de vid: Solaris, Cabernet Sauvignon, Tempranillo y Petit Courbu. La especie que presenta una mayor resistencia al hongo resultó ser Solaris.
