The present invention relates to a herbicidal composition comprising glyphosate herbicide and a quaternary ammonium surfactant having formula (I), wherein R1 is a C1-C5 alkyl radical; R2 is a C1-C5 alkyl radical, or a group R4-O-(PO)u-(EO)v-H, R4 being a C1-C5 alkylene group; R3 is C1-C5 alkyl radical, or a group R5-O-(PO)w-(EO)z-H, R5 being a C1-C5 alkylene group; R7 being CH-O-(PO)x'n-(EO)y'n-H; n being an integer of from 1-4; X = x+x'n+u+w being from 15-35; y = y+y'n+v+z being from 0-15; x'n meaning the sum of the propylene oxide radicals of (R7)n; y'n meaning the sum of the ethylene oxide radicals of (R7)n; each x, x', u, w, y, y', v, z being an integer; and X- is an agriculturally acceptable anion.
La présente invention concerne une composition herbicide contenant un herbicide à base de glyphosate et un agent tensioactif d'ammoniac quaternaire de formule (I), dans laquelle R?1¿ représente un radicla alkyle C¿1?-C¿5?; R?2¿ représente un radical alkyle C¿1?-C¿5? ou un groupe R?4¿-O-(PO)¿u?-(EO)¿v?-H, R?4¿ représentant un groupe alkylène C¿1?-C¿5?; R?3¿ représente un radical alkyle C¿1?-C¿5? ou un groupe R?5¿-O-(PO)¿w?-(EO)¿z?-H, R?5¿ étant un groupe alkylène C¿1?-C¿5?; R?7¿ représente CH-O-(PO)¿x'n?-(EO)¿y'n?-H; n représente un entier de 1 à 4; X = x+?x'¿n?+u+w, et est compris entre 15 et 35; Y = y+?y'¿n?+v+z, et est compris entre 0 et 15; ?x'¿n? représentant la somme des radicaux d'oxyde de propylène de (R?7¿)n; ?y'¿n? représentant la somme des radicaux d'oxyde d'éthylène de (R?7¿)n; chacun de x, x', u, w, y, y', v, z représentant un entier; et X?-¿ représentant un anion acceptable dans l'agriculture.
