ABSTRACT OF THE DISCLOSURE: Herbicidal agents containing an N-azolylmethylhaloace- tanilide of the formula Image I, where R denotes hydrogen or linear or branched alkyl or alkoxy of a maximum of 5 carbon atoms, R1 denotes hydrogen, halogen, or li- near or branched alkyl or alkoxy of a maximum of 5 carbon atoms, R2 denotes hydrogen, halogen, or linear or branched alkyl or alkoxy of a maximum of 5 carbon atoms, R together with R2 forms an alky- lene 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 of 1 to 4 nitrogen atoms which is attached via a ring nitrogen atom and is unsubstituted or mono- or poly- substituted by halogen, phenyl,alkyl, alkoxy, alkylthio or per- fluoroalkyl, each of a maximum of 4 carbon atoms, cyano, carboxy, carbalkoxy of a maximum of 4 carbon atoms in the alkoxy, or alka- noyl of a maximum of 4 carbon atoms, A also denoting a salt of an azole containing 2 or 3 nitrogen atoms and a haloacetanilide of the formula Image II, where R denotes linear or branched alkyl, alkenyl or alkynyl, each of a maximum of 4 carbon atoms. or -A-R1, A denoting- O.Z. 33,315 alkylene of 1 or 2 carbon atoms which may be monosubstituted by ethyl or mono- or disubstituted by methyl, and R1 denoting linear or branched 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 cyclo- alkyl ring, 1,3-dioxolan-2-yl or alkoxycarbonyl of a maximum of 4 carbon atoms in the alkoxy, X denotes chlorine or bromine, and Y1 and Y2 are identical or different and each denotes hydrogen or linear or branched alkyl of a maximum of 4 carbon atoms, Y1 and Y2 only denoting hydrogen when R is linear or branched alkyl, alkenyl or alkynyl, each of a maximum of 4 carbon atoms. The ratio of N-azolylmethylhaloacetanilide of the formula I to haloacetanilide of the formula II is from 1:0.5 to 1:10 parts by weight.
