    摘要: Compounds of the formula (I) or salts thereof ##STR1## in which R.sup.1 is (C.sub.1 -C.sub.4)alkyl, R.sup.2 is halogen, methoxy, ethyl or propyl, R.sup.3 is hydrogen or methyl, E is CH or N and R.sup.4 and R.sup.5 independently of one another are halogen, (C.sub.1 -C.sub.4)alkyl, (C.sub.1 -C.sub.4)alkoxy or (C.sub.1 -C.sub.4)alkylthio, the abovementioned alkyl-containing radicals being unsubstituted or substituted by one or more halogen atoms or one or two (C.sub.1 -C.sub.4)alkoxy or (C.sub.1 -C.sub.4)alkylthio groups, have an excellent herbicidal action against a large number of harmful plants and also growth-regulatory properties on plants.
