Herbicidal agents containing ethyl-N-ethyl-N-bicyclo-[2.2.1]-hept-2-yl-thiolcarbamate of the formula ##STR1## as herbicidal active ingredient and at least one haloacylamide of the formula ##STR2## where R denotes linear or branched haloalkyl of a maximum of 3 carbon atoms, and R.sup.1 and R.sup.2 are identical or different and each denotes linear or branched alkyl of a maximum of 6 carbon atoms which is unsubstituted or substituted by alkoxy of a maximum of 4 carbon atoms or by cyano, R.sup.1 and R.sup.2 further denote cycloalkyl of 3 to 6 carbon atoms, or linear or branched alkenyl or alkynyl of a maximum of 4 carbon atoms, or R.sup.1 and R.sup.2, 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 branched alkyl of a maximum of 4 carbon atoms, or a tetrahydro-1,3-oxazine ring of the formula ##STR3## where R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 are identical or different and each denotes hydrogen or linear or branched alkyl of a maximum of 3 carbon atoms, R.sup.8 denotes hydrogen or linear or branched alkyl of a maximum of 8 carbon atoms, R.sup.9 denotes hydrogen, linear or branched alkyl of a maximum of 8 carbon atoms, alkoxyalkyl of a maximum of 6 carbon atoms or dialkoxyalkyl of a maximum of 8 carbon atoms, or R.sup.8 and R.sup.9 may together form a methylene chain of 4 or 5 carbon atoms, as antagonistic agent.The weight ratio of ethyl-N-ethyl-N-bicyclo-[2.2.1]-hept-2-yl-thiolcarbamate to antagonistic agent is, whether applied together or separately, from 1:1 to 1:0.01.
