Abstract

Acylated aminophenylsulfonylureas, processes for their preparation and their use as herbicides and plant growth regulators. Compounds of the formula (I) and salts thereof ##STR1## in which W.sup.1, W.sup.2, R, n, R.sup.1, R.sup.2, R.sup.4, X, Y and Z are as defined in claim 1 and R.sup.3 is an acyl radical, are suitable as herbicides and plant growth regulators. The herbicides can be prepared by the process variants from claim 5, the novel intermediate products (II), (IV), (VI) and (VIII)* of claims 9 and 10 being employed.
