\"\"<\/a>Le seuil de traitement pour les 4 maladies foliaires a \u00e9t\u00e9 relev\u00e9 cette semaine, ce qui fait que moins de champs ont atteint le seuil. La rouille est la maladie la plus observ\u00e9e et dans 36% des champs, le nouveau seuil de 30% des feuilles atteintes, a \u00e9t\u00e9 d\u00e9pass\u00e9. Le seuil pour la cercosporiose, correspondant \u00e0 20% des feuilles atteintes a \u00e9t\u00e9 d\u00e9pass\u00e9 dans 23% des champs. Par cons\u00e9quent, un deuxi\u00e8me traitement est recommand\u00e9 dans de nombreuses parcelles.<\/p>\n

Nous vous conseillons de r\u00e9aliser des observations avant d\u2019effectuer un traitement. Pour ce faire, contr\u00f4lez la pr\u00e9sence de maladies foliaires en observant attentivement 50 feuilles pr\u00e9lev\u00e9es al\u00e9atoirement dans le champ. Les seuils de traitement relev\u00e9s (\u00e0 partir du 20 ao\u00fbt) pour les quatre principales maladies sont :<\/p>\n

Cercosporiose ou Ramulariose : 20% feuilles atteintes ;\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <\/strong><\/p>\n

O\u00efdiu<\/strong>m ou rouille : 30% feuilles atteintes.<\/strong><\/p>\n

Si vous avez d\u00e9j\u00e0 r\u00e9alis\u00e9 un traitement, il est important de recommencer les observations apr\u00e8s trois semaines, car le produit n\u2019est plus r\u00e9manent apr\u00e8s cette p\u00e9riode. L\u2019observation prendra en compte les taches et pustules vivants. Concernant la cercosporiose, les taches vivantes pr\u00e9sentent des points noirs avec un feutrage blanc.<\/p>\n
