Herbicidal agents containing imidazole herbicide and ether sulfate surfactants
First Claim
1. A herbicidal agent with an effective content ofa) a combination of one or more herbicides of the formulae (I) and (II) or salts thereof ##STR6## where R1 is phenyl, pyridyl or quinolinyl, each of which is optionally monosubstituted or polysubstituted by (C1 -C4)alkyl, (C1 -C4)alkoxy, (C1 -C4)haloalkyl, (C1 -C4)haloalkoxy, a radical of the formulae --COOR3, --COO--CHR3 --COOR3, --CHR3 --COO(C1 -C4 -alkyl) or --CHR3 --COOCHR3 --COOR3, where in each case independently of one another R3 radicals are H or (C1 -C4)alkyl,or by a radical of the formula --CH2 --S(O)n --(C1 -C4)-alkyl where n is 0, 1 or 2, andR2 is H, or a radical of the formula --CONH(C1 -C4 -alkyl);
- --OCO(C1 -C4 alkyl) or --CO(C1 -C4 -alkyl), with one or more compounds of the formula (III) or salts thereof, ##STR7## where Z1 is a radical of the formula --OM, --NHCH(CH3)CONHCH(CH3)COOM or --NHCH(CH3)CONHCH[CH2 CH(CH3)2 ]COOM in which M in each case is hydrogen or an inorganic or organic cation,in a ratio by weight of 1;
3 to 1;
30 of the compounds of the formula (I) or (II) to compounds of the formula (III),b) anionic wetting agents from the group of the C10 -C18 -fatty alcohol polyglycol ether sulfates in the form of the alkali metal salts, ammonium salts or alkaline earth metal salts or of the ammonium salts which are substituted by alkyl or hydroxyalkyl groups, andc) if appropriate, customary inert additives.

Abstract
The agents according to the invention which contain
a) herbicides selected from the group of the imidazolinones of the formula (I) and (II) as claimed in claim 1 and, if desired, additionally phosphinothricin or known analogs,
b) C10 -C18 -fatty alcohol polyglycol ether sulfates as wetting agents and
c) customary additives,
permit a surprisingly lower application rate of active ingredient compared with herbicidal agents without wetting agent b, while having the same effectiveness.
