\"\"<\/a>La semaine derni\u00e8re, 88 parcelles ont \u00e9t\u00e9 suivies afin de d\u00e9tecter les premi\u00e8res maladies foliaires. Les premiers sympt\u00f4mes de cercosporiose ont d\u00e9j\u00e0 \u00e9t\u00e9 observ\u00e9s dans 22 parcelles. Consultez la situation actuelle sur notre site internet : Carte des maladies foliaires<\/a>.<\/p>\n

Ces premiers sympt\u00f4mes ont \u00e9t\u00e9 observ\u00e9s dans des parcelles r\u00e9parties sur l’ensemble du pays, ind\u00e9pendamment de la date de semis et du niveau de tol\u00e9rance vari\u00e9tale \u00e0 la cercosporiose. D\u00e8s l’apparition des premi\u00e8res taches de cercosporiose, nous recommandons d’intervenir afin de ma\u00eetriser la maladie et de limiter sa propagation.<\/p>\n

Veillez toutefois \u00e0 ne pas confondre cercosporiose<\/strong> avec pseudomonas<\/strong>. Un crit\u00e8re distinctif important est la pr\u00e9sence de petits points noirs (fructifications), visibles sur les taches de cercosporiose \u00e0 l’aide d’une loupe.<\/p>\n\n\n\n

\"\"<\/a>En pr\u00e9sence de cercosporiose, nous recommandons d’utiliser un fongicide efficace, de pr\u00e9f\u00e9rence \u00e0 base de prothioconazole et associ\u00e9 \u00e0 un partenaire de m\u00e9lange. Pour vous aider \u00e0 choisir la strat\u00e9gie de traitement la plus adapt\u00e9e, nous vous invitons \u00e0 consulter notre Fongi Memo<\/a><\/span>. Vous y trouverez un aper\u00e7u des fongicides disponibles, des strat\u00e9gies de traitement recommand\u00e9es ainsi que de l’influence de la tol\u00e9rance vari\u00e9tale sur la lutte contre les maladies foliaires. La Fongi Memo est disponible sur notre site web ou via le lien suivant : Fongi Memo.<\/p>\n

Outre la cercosporiose, de la rouille a \u00e9galement \u00e9t\u00e9 observ\u00e9e sur six sites. \u00c0 ce jour, le seuil de nuisibilit\u00e9 n’est toutefois atteint sur aucune de ces parcelles.<\/p>\n

Vous trouverez ci-dessous un aper\u00e7u des seuils de nuisibilit\u00e9 applicables aux principales maladies foliaires.<\/p>\n
