La m\u00e9t\u00e9o plus s\u00e8che et plus cl\u00e9mente des derniers jours favorise le d\u00e9veloppement des cultures ainsi que de la faune entomologique : un plus grand nombre de pucerons verts apt\u00e8res sont observ\u00e9s dans l\u2019ensemble des r\u00e9gions, mais les populations d\u2019auxiliaires pr\u00e9sentes dans les parcelles sont plus nombreuses et diverses. La majorit\u00e9 des parcelles restent cependant sous le seuil de traitement de 2 pucerons verts apt\u00e8res par 10 plantes (en vert sur la carte). 10\u2009% des parcelles suivies ont atteint au moins le premier seuil de traitement. Le seuil de deuxi\u00e8me traitement a \u00e9t\u00e9 observ\u00e9 pour la premi\u00e8re fois dans 3 parcelles situ\u00e9es dans la r\u00e9gion de Li\u00e8ge et de Tirlemont. Enfin, 30 % des parcelles sont toujours sous protection.<\/p>\n

Nous continuons donc vivement \u00e0 recommander de r\u00e9aliser les observations. Si le seuil de 2 pucerons verts apt\u00e8res par 10 plantes est atteint, un traitement insecticide peut \u00eatre r\u00e9alis\u00e9. Nous recommandons un traitement avec Teppeki \u00e0 0,140 kg\/ha ou Movento \u00e0 0,45 l\/ha. \u00c0 partir du stade \u00ab d\u00e9but de recouvrement de l\u2019inter-rang \u00bb, un traitement avec Gazelle \u00e0 0,25 kg\/ha est aussi possible.<\/p>\n
