Les rangs ferment dans un grand nombre de parcelles, mais certaines, notamment dans le Hainaut et dans le nord du pays, ont \u00e9t\u00e9 sem\u00e9es il y a une dizaine de jours et sont encore au stade <\/span>cotyl\u00e9donaires \u2013 2-feuilles.<\/p>\n

Dans les derniers semis, des atomaires sont parfois observ\u00e9s au c\u0153ur des feuilles. Peu de pucerons sont observ\u00e9s, mais les situations restent tr\u00e8s variables d’une parcelle \u00e0 l’autre. Une vigilance accrue est donc n\u00e9cessaire dans les betteraves au stade 2 \u00e0 6 feuilles, car c’est le stade o\u00f9 la betterave est la plus vuln\u00e9rable.<\/p>\n

Nous vous conseillons alors de poursuivre vos observations jusqu’\u00e0 fermeture de l\u2019inter-rang et si votre dernier traitement date de plus de 15 jours<\/strong>. Si le seuil de 2 pucerons verts apt\u00e8res par 10 plantes est atteint, un traitement insecticide est recommand\u00e9. Les traitements possibles sont\u00a0: Teppeki \u00e0 0,140 kg\/ha, Movento \u00e0 0,45 l\/ha. \u00c0 partir du stade d\u00e9but de recouvrement de l\u2019inter-rang, un traitement avec Gazelle \u00e0 0,25 kg\/ha est aussi possible.<\/p>\n
