<p>The invention is concerned with a herbicidal agent active in combating unwanted plant growth in Indian corn and other cereal crops containing 0.1 to 95 parts by weight of a substituted acetanilide of the formula I, wher R denotes hydrogen, linear or branched alkyl or alkoxy of up to 5 carbon atoms, R1 denotes hydrogen, halogen, or linear or branched alkyl or alkoxy of up to 5 carbon atoms, R2 denotes hydrogen, halogen, or linear or branched alkyl or alkoxy of up to 5 carbon atoms, or R together with R2 denotes an alkylene chain of up to 6 carbon atoms which is linked in the o-position and may be substituted by linear or branched alkyl of up to 4 carbon atoms, X denotes chlorine or bromine, and A denotes an azole ring containing 1 to 4 nitrogen atoms, which is attached via a ring nitrogen atom and may be mono- or polysubstituted by halogen, phenyl, alkyl, alkoxy, alkylthio or perfluoroalkyl, each alkyl of up to 4 carbon atoms, cyano, carboxy, carbalkoxy of up to 4 carbon atoms in the alkoxy, or alkanoyl of up to 4 carbon atoms, or A denotes a salt of an azole ring containing 2 or 3 nitrogen atoms, as herbicidal active ingredient, and of a dichloracetamide of the formula II, where R1 and R2 are identical or different and each denotes linear or branched alkyl or a maximum of 6 carbon atoms which is unsubstituted or substituted by alkoxy of a maximum of 4 carbon atoms or by cyano, R1 and R2 further each denote linear or branched alkenyl or alkynyl of a maximum of 4 carbon atoms or cycloalkyl of 3 to 6 carbon atoms, or R1 and R2, together with the nitrogen atom whose substituents they are, form a 4- to 9-membered, saturated monocyclic or bicyclic ring which is unsubstituted or mono- or polysubstituted by linear or brancked alkyl of a maximum of 4 carbon atoms, as antagonistic agent, the ratio of acetanilide to N-dichloroacetyl-2,2-dimethyl-1,3-oxazolidine being from 1:2 to 1:0.05 parts by weight.</p> |
