Patent

CA 2454488

The invention relates to herbicide combinations containing components (A) and (B), which exhibit an improved herbicidal action. According to the invention: (A) is one or more herbicides of formula (I) or the salts thereof, in which R1 represents a (C1-C8) alkyl, (C3-C4) alkenyl, (C3-C4) alkinyl or (C1-C4) alkyl, which is monosubstituted to tetrasubstituted by radicals from the group containing halogen and/or (C1-C2) alkoxy, R2 represents I or CH2NHSO2CH3, R3 represents methyl or methoxy and Z represents N or CH; and (B) is one or more herbicides, which are selectively effective in several monocotylic cultures against monocotylic and/or dicotylic harmful plants from the group of compounds consisting of (B1) flucarbazone, (B2) BAY MKH 6561 (procarbazone), (B3) florasulam, (B4) halosulfuron, (B5) tritosulfuron, (B6) picolinafen, (B7) cinidon ethyl, (B8) mesotrione, (B9) metosulam, (B10) clopyralid, (B11) flufenacet, (B12) flumetsulam, (B13) flupoxam, (B14) prosulfocarb, (B15) flurtamone, (B16) aclonifen, (B17) hexazinone, (B18) asulam, (B19) diuron, (B20) ametryn, (B21) isoxaflutole, (B22) amicarbazone, and (B23) trifloxysulfuron, excepting herbicide combinations, which contain (A) one or more herbicides from the group of compounds of formula (I) and the salts thereof, in which R1=(C1-C8) alkyl, (C3-C4) alkenyl, (C3-C4) alkinyl or (C1- C4) alkyl, which is monosubstituted to tetrasubstituted by radicals from the group containing halogen and (C1-C2) alkoxy, R2= CH2NHSO2CH3, R3= methoxy and Z = CH, and (B) is one or more herbicides from the group of compounds containing metosulam (B9), flupoxam (B13), prosulfocarb (B14) and flurtamone (B15).

L'invention concerne des combinaisons herbicides contenant les composants (A) et (B) et présentant un meilleur effet herbicide. Selon l'invention, (A) est un ou plusieurs herbicides ou les sels de ceux-ci, de formule (I), dans laquelle R?1¿ est (C¿1?-C¿8?)-alkyl, (C¿3?-C¿4?)-alcényl, (C¿3?-C¿4?)-alkinyl ou (C¿1?-C¿4?)-alkyl substitué une à quatre fois par des restes du groupe halogène et/ou (C¿1?-C¿2?)-alkoxy ; R?2¿ est I ou CH¿2?NHSO¿2?CH¿3? ; R?3¿ est méthyl ou méthoxy ; et, Z est N ou CH. Par ailleurs, (B) est un ou plusieurs herbicides actifs sélectivement dans certaines cultures monocotylédones contre des plantes nuisibles monocotylédones et/ou dicotylédones, choisis parmi (B1) flucarbazone, (B2) BAY MKH 6561 (procarbazone), (B3) florasulame, (B4) halosulfurone, (B5) tritosulfurone, (B6) picolinafène, (B7) cinidonéthyl, (B8) mésotrione, (B9) métosulame, (B10) clopyralide, (B11) flufénacète, (B12) flumétsulame, (B13) flupoxame, (B14) prosulfocarb, (B15) flurtamone, (B16) aclonifène, (B17) hexazinone, (B18) asulame, (B19) diurone, (B20) amétryne, (B21) isoxaflutole, (B22) Amicarbazone, et (B23) trifloxysulfurone, à l'exception de combinaisons herbicides contenant (A) un ou plusieurs herbicides du groupe des composés et leurs sels, de formule (I), dans laquelle R?1¿ est (C¿1?-C¿8?)-alkyl, (C¿3?-C¿4?)-alcényl, (C¿3?-C¿4?)-alkinyl ou (C¿1?-C¿4?)-alkyl substitué une à quatre fois par des restes du groupe halogène et/ou (C¿1?-C¿2?)-alkoxy, R?2¿ est CH¿2?NHSO¿2?CH¿3?, et R?3¿ est méthyl ou méthoxy, Z est N ou CH, et (B) est un ou plusieurs herbicides du groupe des composés Métosulame (B9), flupoxame (B13), prosulfocarb (b14) et flurtamone (B15).
