CA 2214387

The invention concerns plant-protection formulations containing a cyclohexenone oxime ether of general formula (I) in which groups R1 to R6 are as follows: R1 is ethyl or propyl; R2 is hydrogen or an equivalent of an agriculturally useful cation; R3 is 2-(thioethyl)propyl, tetrahydrothiopyran-3- yl, tetrahydrothiopyran-4-yl, tetrahydropyran-3-yl, tetrahydropyran-4-yl, 1- (methylthio)cyclopropyl, 5-(iso-propyl)isoxazol-3-yl, 2,5-dimethylpyrazol-3- yl, 2,3,6-trimethylphenyl or 2,4,6-trimethyl-3-butyrylphenyl; R4 and R5, independently of each other, are hydrogen, methyl or methoxycarbonyl; Alk is CH2CH2, CH2CH(CH3), CH2CH=CH, CH2CH=C(Cl) or CH2CH2CH=CH; R6 is hydrogen, pyhenyl, halophenyl, dihalophenyl, phenoxy, halophenoxy or dihalophenoxy; plus a water-soluble basic salt of an acide with a pKs value greater than 5, but excluding alkali-metal hydroxides and alkali-metal carbonates. The invention also concerns the preparation of such formulations and their use as herbicides.

La présente invention concerne des formulations phytosanitaires contenant un cyclohexénonoximéther correspondant à la formule (I), dans laquelle R?1¿ à R?6¿ ont les significations suivantes: R?1¿ est éthyle ou propyle; R?2¿ est hydrogène ou un équivalent d'un cation à usage agricole; R?3¿ est 2-(thiothyl)propyle, tétrahydrothiopyran-3-yle, tétrahydrothiopyran-4-yle, tétrahydropyran-3-yle, tétrahydropyran-4-yle, 1-(méthylthio)cyclopropyle, 5-(iso-propyl)isoxazole-3-yle, 2,5-diméthylpyrazol-3-yle, 2,4,6-triméthylphényle ou 2-4,6-triméthyl-3-butyrylphényle; R?4¿ et R?5¿, indépendant l'un de l'autre, représentent hydrogène, méthyle ou méthoxycarbonyle; Alk est CH¿2?CH¿2?, CH¿2?CH(CH)¿3?, CH¿2?CH=CH, CH¿2?CH=C(cl) ou CH¿2?CH¿2?CH=CH; R?6¿ est hydrogène, phényle, halophényle, dihalophényle, phénoxy, halophénoxy ou dihalophénoxy; plus un sel basique soluble dans l'eau, provenant d'un acide de valeur pKs supérieure à 5, mais à l'exclusion des hydroxydes de métaux alcalins et des carbonates de métaux alcalins. L'invention concerne aussi la préparation des ces formulations et leur utilisation comme herbicides.
