Au 14 mai, des pucerons verts apt\u00e8res ont \u00e9t\u00e9 observ\u00e9s <\/strong>dans 14% des champs du r\u00e9seau des champs d\u2019observation (14 parcelles sur 98 parcelles observ\u00e9es). Aucun champ n\u2019a atteint le seuil de traitement<\/u><\/strong> qui est de 2 pucerons verts apt\u00e8res par 10 plantes. Le conseil est donc d\u2019attendre avant de traiter tout en surveillant la situation de vos champs. La vigilance est de mise!<\/p>\n

Les colonies de pucerons noirs restent pr\u00e9sentes mais semblent se stabiliser. Il s\u2019agit de surveiller leur d\u00e9veloppement et de n\u2019intervenir que si le seuil est atteint (30 \u00e0 50 % des plantes avec colonies).<\/p>\n

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