Cette semaine, sur les 69 parcelles suivies dans le cadre du r\u00e9seau champs d\u2019observation, nous avons pu constater que :<\/p>\n

\u00a0<\/p>\n

– 48% pr\u00e9sentent des sympt\u00f4mes de cercosporiose et dans 14% des champs le seuil de traitement est atteint,<\/p>\n

– 87% pr\u00e9sentent de sympt\u00f4mes de rouille et dans 52% le seuil de traitement est atteint,<\/p>\n

– 51% pr\u00e9sentent des sympt\u00f4mes d\u2019o\u00efdium et dans 23% le seuil de traitement est atteint,<\/p>\n

– 29% n\u2019atteignent pas le seuil de traitement pour une des 4 maladies foliaires.<\/p>\n

Vous pouvez suivre l\u2019\u00e9volution des maladies foliaires via la carte<\/a>.<\/p>\n

Il est vivement recommand\u00e9 d\u2019effectuer des observations dans vos parcelles et de traiter d\u00e8s que le seuil de traitement pour une des 4 maladies<\/strong> est atteint. Les seuils de traitement pour les diff\u00e9rentes maladies sont repris ci-dessous. Une feuille est consid\u00e9r\u00e9e comme atteinte si au moins une tache est observ\u00e9e sur la feuille.<\/p>\n\n\n\n\n\n
