Les conditions froides depuis une semaine sont d\u00e9favorables aux vols de pucerons verts. Au 7 mai, il y avait tr\u00e8s peu de champs avec la pr\u00e9sence de pucerons verts et aucun champ n\u2019atteignait le seuil de 2 pucerons verts apt\u00e8res par 10 plantes. Le message est donc d\u2019attendre avant de traiter tout en surveillant la situation de vos champs.<\/p>\n

Les colonies de pucerons noirs restent pr\u00e9sentes mais se d\u00e9veloppent \u00e9galement lentement. Il s\u2019agit de surveiller leur d\u00e9veloppement et de n\u2019intervenir, avec un produit s\u00e9lectif et sp\u00e9cifique puceron, que si leur nombre et taille deviennent importants (30 \u00e0 50 % des plantes avec colonies).<\/p>\n

Pour les champs sem\u00e9s avec un traitement Poncho ou Cruiser, aucune intervention n\u2019est requise.<\/p>\n

Suivez l\u2019\u00e9volution des populations de pucerons verts<\/a> via la carte des probl\u00e8mes signal\u00e9s en culture pour les mois de mai et juin.<\/p>\n
