Abstract

Compounds of the formula I or salts thereof ##STR1## where R.sup.1 is ethyl, propyl or isopropyl, PA1 R.sup.2 is halogen, NO.sub.2, CF.sub.3, CN, alkyl, alkoxy, alkylthio or alkoxycarbonyl, PA1 n is 0, 1, 2 or 3, Y is O or S, PA1 R.sup.3 is hydrogen, alkyl, alkenyl, alkynyl or alkoxy; PA1 R.sup.4 is a heterocyclic radical of the formulae ##STR2## E is CH or N; G is O or CH.sub.2, R.sup.5 and R.sup.6 are hydrogen, halogen, or are alkyl, alkoxy or alkylthio, which are optionally substituted by halogen, alkoxy or alkylthio, or are --NR.sup.12 R.sup.13, --OCHR.sup.7 --CO.sub.2 R.sup.12, (C.sub.3 -C.sub.6 cycloalkyl, (C.sub.3 -C.sub.5)alkenyl, (C.sub.2 -C.sub.4) -alkynyl, (C.sub.3 -C.sub.5)alkenyloxy or (C.sub.3 -C.sub.5 (alkynyloxy; R.sup.7 is hydrogen or alkyl, R.sup.8 is alkyl, --CHF.sub.2 or --CH.sub.2 CF.sub.3 ; R.sup.9 and R.sup.10 are hydrogen, alkyl, alkoxy or halogen; R.sup.11 is hydrogen, alkyl, --CHF.sub.2 or CH.sub.2 CF.sub.3 ; R.sup.12 and R.sup.13 independently of one another are hydrogen, alkyl, alkenyl or alkynyl, possess outstanding herbicidal and plant growth-regulating properties.
