Abstract

L'invention concerne un herbicide pour rizières, à haute sécurité pour les plants de riz et très efficace contre un large éventail de mauvaises herbes annuelles et vivaces dans les rizières. L'herbicide est très efficace également sur les mauvaises herbes résistant aux herbicides à base de sulfonylurée. La composition est caractérisée en ce qu'elle renferme comme éléments actifs 2-[4-(2,4-dichloro-m-toluoyl)-1,3-diméthyl-1H-pyrazol-5-yloxy]-4'-méthylacétophénone (dénomination usuelle: benzofenap) et un ou plusieurs composés choisis dans le groupe suivant: bensulfuron-méthyle, azimsulfuron, pyrazosulfuron-éthyle et imazosulfuron.
