Glyphosate formulations which are effective even when employed at dosages below the dosage currently recommended for post-emergent herbicidal or plant growth regulant use are described. They are formulated as water solutions or powders or granules of (a) one or more agriculturally acceptable amine, alkali metal, alkylsulfonium, alkylphosphonium, sulfonylamine, and/or aminoguanidine salts of glyphosate; (b) at least one water-soluble long chain aliphatic hydrocarbyl dimethyl amine oxide in which the hydrocarbyl group is a linear or substantially linear saturated or olefinically unsaturated aliphatic group having in the range of 8 to 22 carbon atoms; and (c) at least one water- soluble quaternary ammonium halide having in the range of 8 to 40 carbon atoms in the molecule.

L'invention concerne des formulations de glyphosate qui sont efficaces lorsqu'elles sont employées à des dosages inférieurs à ceux généralement recommandés et qui sont utilisées en post-levée comme herbicides ou régulateurs de la croissance des végétaux. Ces produits sont formulés sous forme de solutions aqueuses, ou de poudres ou de granulés renfermant: (a) au moins une amine acceptable en agriculture, des métaux alcalins, des sels d'alkylsulfonium, d'alkylphosphonium, de sulfonylamine et/ou d'aminoguanidine de glyphosate; (b) au moins un oxide, d'hydrocarbyle diméthyl amine, aliphatique, à longue chaîne, soluble dans l'eau dans lequel le groupe hydrocarbyle est un groupe aliphatique linéaire, ou sensiblement saturé linéaire ou oléfiniquement insaturé, possédant entre 8 et 22 atomes de carbone; et (c) au moins un halogénure d'ammonium quaternaire soluble dans l'eau possédant entre 8 et 40 atomes de carbone dans la molécule.
