Abstract

Novel benzoic acid compounds of the formula ##STR1## in which R is alkyl or substituted alkyl of up to 6 carbon atoms, where the substituents are selected from halogen, or R is aryl which is optionally substituted by halogen and/or by alkyl of up to 4 carbon atoms, R.sup.1 is alkyl, alkoxy or alkylmercapto, of in each case up to 4 carbon atoms, or halogen, R.sup.2 is hydrogen, R.sup.3 is hydrogen or halogen, R.sup.4 is hydroxyl, alkoxy of 1 to 6 carbon atoms or an amino group which is optionally substituted by one or two alkyl radicals each of up to 6 carbon atoms, and R.sup.5 is halogen or alkyl of up to 4 carbon atoms; are outstandingly effective and selective as herbicides.
