\"wortelziekte\"<\/a>Il est recommand\u00e9 de parcourir ses champs avant arrachage et de veiller \u00e0 adapter l’ordre d’arrachage de ses parcelles pour limiter l’incidence des maladies racinaires. Les champs infect\u00e9s par l’une ou l’autre des maladies d\u00e9crites ci-apr\u00e8s doivent \u00eatre arrach\u00e9s prioritairement aux autres pour limiter le niveau d’infestation dans le sol et dans les betteraves arrach\u00e9es.
\nLes pertes de rendement et de qualit\u00e9 industrielle des betteraves atteintes par ces maladies restent limit\u00e9es pour les courtes dur\u00e9es de conservation. Des illustrations de ces maladies sont disponibles sur le site Internet de l’IRBAB.
\nLes maladies racinaires de la betterave pr\u00e9sentes en fin de p\u00e9riode de v\u00e9g\u00e9tation sont souvent difficiles \u00e0 identifier, surtout apr\u00e8s arrachage et mise en tas.
\nAvant arrachage, la r\u00e9partition et l’intensit\u00e9 du sympt\u00f4me au champ, l’aspect du bouquet foliaire et des betteraves voisines, la zone du champ o\u00f9 les betteraves sont attaqu\u00e9es, la vari\u00e9t\u00e9 sont des \u00e9l\u00e9ments utiles pour identifier l’origine du probl\u00e8me.
\nLes principales maladies racinaires observ\u00e9es \u00e0 la r\u00e9colte peuvent \u00eatre dues \u00e0 :
\n– une carence en bore<\/strong>, avec un sympt\u00f4me de pourriture du coeur (point v\u00e9g\u00e9tatif de la betterave) et un developpement de moisissures secondaires dans le collet (cas graves),
\n– une attaque de n\u00e9matode du collet<\/strong> : une partie du collet peut \u00eatre profond\u00e9ment creus\u00e9e. Des pourritures secondaires peuvent ensuite se d\u00e9velopper dans les tissus attaqu\u00e9s (parfois fort en profondeur dans la racine),
\n– une attaque de rhizoctone. Il faut alors distinguer le rhizoctone brun<\/strong> du rhizoctone violet<\/strong> pour savoir s’il y a lieu d’utiliser par la suite des vari\u00e9t\u00e9s tol\u00e9rantes au rhizoctone brun (NB: il n’y a pas de vari\u00e9t\u00e9s tol\u00e9rantes au rhizoctone violet).
\nD’autres maladies, plus difficiles \u00e0 identifier, peuvent \u00eatre ponctuellement observ\u00e9es sur quelques betteraves.<\/p>\n","protected":false},"excerpt":{"rendered":"
