Abstract

L'invention concerne une composition herbicide contenant en tant qu'ingrédients actifs du 2-chloro-4-fluoro-5-(4-méthyl-5-trifluorométhyl-3-pyridazinon-2-yl)phényl hydrocarbyl éther C1-C5 non cyclique et du 4'fluoro-N-isopropyl-2(5-trifluorométhyl-1,3,4-thiadiazol-2-yloxy)-acétanilide, et un procédé d'élimination des mauvaises herbes à l'aide de cette composition. Lorsqu'elle est appliquée aux sols ou sur les mauvaises herbes, cette composition peut éliminer efficacement les mauvaises herbes dans les sols agricoles ou non agricoles, présente une activité accrue par synergie comparée à l'utilisation isolée de chacun des ingrédients, peut être appliquée à de faibles doses, est capable d'éliminer un large spectre de plantes nuisibles sans développer d'effets néfastes dans les cultures, en particulier dans les champs de blé, d'orge, d'avoine, de seigle et de maïs.
