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 as the only herbicide(s) used in the forming composition; and (b) one or more water-soluble particular types of aliphatic hydrocarbyl sulfonic acid or agriculturally acceptable salt or ester thereof as the only surfactants used in forming the composition. The hydrocarbyl group of the sulfonate is a saturated aliphatic group having in the range of 10 to 18 carbon atoms and is terminally substituted by the foregoing functionality.
La présente invention décrit des formulations de glyphosate agissant efficacement, même aux doses inférieures recommandées pour les herbicides post-émergence et la régulation de croissance des plantes. Lesdites compositions ont été établies selon diverses formulations : solutions aqueuses, poudres ou granulés de (a) un ou plusieurs sels de glyphosate amine, métal alcalin, alkylsulfonium, alkylphosphonium, sulfonylamine et/ou aminoguanidine comme le ou les seuls herbicides entrant dans ladite composition et acceptables dans le domaine agricole; et (b) un ou plusieurs types particuliers d'acide sulfonique hydrocarbyl aliphatique ou autre sel ou ester desdits, acceptables dans le domaine agricole, comme les seuls surfactants entrant dans ladite composition. Le groupe hydrocarbyl du sulfonate est un groupe aliphatique saturé possédant une plage atomique de 10 à 18 atomes de carbone et qui est substitué en phase terminale par la fonction ci-dessus décrite.
