Les parcelles sem\u00e9es vers le 20 mars atteignent maintenant progressivement le stade de 2 vraies feuilles (BBCH 12). Dans de nombreux cas, cela signifie que le 2\u1d49 traitement FAR va \u00eatre r\u00e9alis\u00e9.<\/p>\n

\u00c0 partir du stade BBCH 12, \u00ab Centium<\/strong> \u00bb et \u00ab Matrigon<\/strong> \u00bb sont \u00e9galement homologu\u00e9s et peuvent donc \u00eatre utilis\u00e9s pour \u00e9largir le spectre d\u2019action.<\/p>\n

En pr\u00e9sence de mercuriale annuelle et d\u2019arroche : FAR + Centium<\/strong> (0,02 \u00e0 0,03 l\/ha)<\/p>\n

Lorsque Venzar<\/strong> est \u00e9galement utilis\u00e9 dans les programmes, privil\u00e9giez Venzar au FAR 2 et appliquez Centium \u00e0 partir du FAR 3 ou 4.<\/p>\n

Pour lutter contre la renou\u00e9e des oiseaux, l\u2019arroche et le ch\u00e9nopode, Venzar peut aussi \u00eatre utilis\u00e9 lors du 2\u1d49 FAR. La dose peut \u00e9ventuellement \u00eatre augment\u00e9e jusqu\u2019\u00e0 0,15 l\/ha maximum en fonction de la pression des adventices.<\/p>\n

Pour la lutte contre la petite cig\u00fce et les ast\u00e9rac\u00e9es (comme la camomille et le s\u00e9ne\u00e7on), Matrigon<\/strong> peut \u00eatre appliqu\u00e9 d\u00e8s le stade 1 feuille des adventices et en conditions poussantes. L\u2019utilisation de Matrigon est \u00e9galement recommand\u00e9e pour contr\u00f4ler les repousses de chicor\u00e9e.
En cas de pression normale : FAR + Matrigon (0,3 \u2013 0,5 l\/ha)<\/p>\n

Un second passage peut \u00eatre n\u00e9cessaire en fonction des adventices pr\u00e9sentes et du stade des betteraves.<\/p>\n

En conditions s\u00e8ches et en cas de forte pression des adventices, la dose de \u00ab Betanal \u00bb peut \u00eatre augment\u00e9e jusqu\u2019\u00e0 50 %.<\/p>\n
