The present invention describes glyphosate salts of ether amines as compounds and compositions, including their methods of use. The compounds include glyphosate salts of the formula Z-CH2-NH-CH2-POR1R2 (I), wherein Z is COOH, COSH, COCl, COBr, COF, COI, or COR3; R1, R2, and R3 are each independently OH or OR4 such that at least one of R1, R2, and R3 are OR4; and R4 is an ether amine salt-forming cation of the formula H3N+-R5-O-R6 (II), wherein R5 and R6 are each independently C1-C6 alkyl, C2-C6 alkene, or C2-C6 alkyne. The compositions included herein contain at least the above-described glyphosate salt in combination with a carrier. This composition is useful in methods to inhibit the growth of unwanted plants by contacting the plant with an herbicidally effective amount of the composition.
La présente invention concerne des sels de glyphosate d'éther amines en tant que composés et compositions, ainsi que des méthodes d'utilisation de ceux-ci. Lesdits composés comprennent des sels de glyphosate de formule (I) : Z-CH¿2?-NH-CH¿2?-POR¿1?R¿2? (I), dans laquelle Z est COOH, COSH, COCl, COBr, COF, COI ou COR¿3? ; R¿l?, R¿2? et R¿3? représentent chacun indépendamment OH ou OR¿4? de telle sorte qu'au moins un des éléments parmi R¿l?, R¿2? et R¿3? représente OR¿4? ; et R¿4? est un cation formant des sels d'éther amines, de formule (II) : H¿4?N-R¿5?-O-R¿6? (II), dans laquelle R¿5? et R¿6? représentent chacun indépendamment alkyle C¿1?-C¿6?, alcène C¿2?-C¿6? ou alkyne C¿2?-C¿6?. Les compositions mentionnées contiennent au moins le sel de glyphosate cité ci-dessus en combinaison avec un support. Ce type de composition est utile dans des procédés destinés à inhiber la croissance de plantes parasites, ces procédés consistant à mettre en contact la plante avec une quantité herbicide efficace de la composition.
