Abstract

A herbicidal composition containing one or more substituted 2-aminothiophenes of the formula I ##STR1## where R.sup.1 and R.sup.2 together from a C.sub.4 -alkylene chain to which a benzene ring may be fused, R.sup.3 is --CN or CX--R.sup.6, where R.sup.6 is hydroxyl, C.sub.1 -C.sub.4 -alkoxy or amino, R.sup.4 is hydrogen or a phenyl group which may carry one or two nitro radicals, EQU --PO(OR.sup.8).sub.2, --CX--R.sup.9, --SO.sub.2 R.sup.10, --CX--N(H) --CO--R.sup.8 or --CX--N(R.sup.7)--SO.sub.2 --R.sup.11, where R.sup.8 is hydrogen, C.sub.1 -C.sub.4 -alkyl or phenyl group R.sup.9 is C.sub.1 -C.sub.20 -alkyl, partially or completely halogenated C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.6 -cycloalkyl, or amino, C.sub.1 -C.sub.4 -alkylamino, C.sub.3 -C.sub.8 -cycloalkylamino, phenyl or phenylamino, where the aromatic moiety may carry at least one of nitro and halogen; R.sup.10 is C.sub.1 -C.sub.4 -alkyl or phenyl, which may carry one C.sub.1 -C.sub.4 -alkyl radical; R.sup.11 is pyrrolidin-1-yl, piperidin-1-yl, morpholin-4-yl or piperazin-1-yl, where the heterocyclic structures may carry one C.sub.1 -C.sub.4 -group; R.sup.5 is hydrogen; or R.sup.4 and R.sup.5 together f…
