COMBINACION DE HERBICIDAS

El presente invento se refiere a una combinacion de herbicidas, que contiene componentes (A) Y (B), significando a uno o varios herbicidas tomados del conjunto formado por compuestos de la formula (l) o sus sales. New herbicide combinations contain (A) one or more of N-(pyrimidinyl or s-triazinyl)-N'-(3-(5,6-dihydro-1,4,2-dioxazin-3-yl)-pyridin-2-ylsulfonyl)-ureas (I) and their salts and (B) one or more of 2,4-diamino-s-triazines, in which an amino group is N-substituted by a (hetero)aryl-(hetero)alkyl group. New herbicide combinations contain (A) one or more of sulfonyl-ureas of formula (I) and their salts and (B) one or more of 2,4-diamino-s-triazines, in which an amino group is N-substituted by a (hetero)aryl-(hetero)alkyl group. A : N or CR 11>; R 11>H, alkyl, halo or haloalkyl; R 1>H or (all optionally substituted (os)) alkyl, alkoxy, alkoxyalkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aralkyl or aryl; R 2>, R 3>H, halo or (all os by halo) alkyl, alkoxy, alkylthio, alkylamino or dialkylamino; R 4>-R 8>H, halo, CN, SCN or (all os by halo) alkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, alkylamino, alkylcarbonyl, alkoxycarbonyl or alkylaminocarbonyl; alkyl or alkylene moieties have 1-6C (except in R 4>-R 8>, where they have 1-3C), alkenyl or alkynyl moieties 2-6C, cycloalkyl moieties 3-6C and aryl moieties 6-10C. An independent claim is included for a method for non-selective control of unwanted plant growth, involving application of the herbicides (A) and (B), together or separately, preferably to the area in which the plants grow. [Image] ACTIVITY : Herbicide. Combinations of (A) and (B) are stated to show strongly synergistic herbicidal activity against a broad spectrum of grassy and broad-leaf plants (e.g. Sinapis alba, Echinochloa crus-galli, Setaria viridis, Amaranthus retroflexus, Abutilon threophrasti and Panicum millaceum) on pre- or post-emergence application at rates of 100 g/ha or less, but no quantitative results for individual active agent combinations are given. MECHANISM OF ACTION : Acetolactate synthase inhibitor; Protein synthesis inhibitor; Cellulose biosynthesis inhibitor; Cell wall formation suppressor.
