3-Halo-3-hetarylcarboxylic acid derivatives having the formula I ##STR1## in which R is a formyl group, a group CO.sub.2 H or a radical which can be hydrolyzed to COOH, and the remaining substituents have the following meanings: R.sup.2 and R.sup.3 are halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy or C.sub.1 -C.sub.4 -alkylthio; X is nitrogen or CR.sup.13, where R.sup.13 is hydrogen or together with R.sup.3 forms an alkylene or alkenylene chain in which in each case one methylene group is replaced by oxygen; R.sup.4 is an unsubstituted or substituted five- or six-membered heteroaromatic ring which contains one to three nitrogen atoms and/or one sulfur or oxygen atom; R.sup.5 is hydrogen, substituted or unsubstituted alkyl, alkenyl, alkynyl, cycloalkyl or phenyl; Y is sulfur, oxygen or a single bond; and Z is halogen. The derivatives I having herbicidal and plant-growth regulating properties.
