ABSTRACT:
Herbicidal agents containing an N-azolylmethylhaloacetanilide of the formula ##STR1## where R denotes hydrogen or alkyl or alkoxy of a maximum of 5 carbon atoms, R.sup.1 denotes hydrogen, halogen, or alkyl or alkoxy of a maximum of 5 carbon atoms, R.sup.2 denotes hydrogen, halogen, or alkyl or alkoxy of a maximum of 5 carbon atoms, R together with R.sup.2 forms an alkylene chain of a maximum of 6 carbon atoms which is linked in the o-position and is unsubstituted or substituted by linear alkyl of a maximum of 4 carbon atoms, X denotes chlorine or bromine, and A denotes an azole and a haloacetanilide of the formula ##STR2## where R denotes alkyl, alkenyl or alkynyl, each of a maximum of 4 carbon atoms, or --A--R.sup.1, A denoting alkylene of 1 or 2 carbon atoms which may be monosubstituted by ethyl or mono- or disubstituted by methyl, and R.sup.1 denoting alkoxy, haloalkoxy, alkenoxy, alkynoxy or alkoxyalkoxy, each of a maximum of 4 carbon atoms, cycloalkoxy or cycloalkylmethoxy with 3 to 6 carbon atoms in the cycloalkyl ring, 1,3-dioxolan-2-y1 or alkoxycarbonyl of a maximum of 4 carbon atoms in the alkoxy, X denotes chlorine or bromine, and Y.sup.1 and Y.sup.2 each denotes hydrogen or alkyl of a maximum of 4 carbon atoms, Y.sup.1 and Y.sup.2 only denoting hydrogen when R is alkyl, alkenyl or alkynyl, each of a maximum of 4 carbon atoms.
The ratio of N-azolylmethylhaloacetanilide of the formula I to halcacetanilide of the formula II is from 1:0.5 to 1:20 parts by weight.
