N-Arylsulfonyl-N'-pyrimidinylureas of the general formula and the salts of these compounds with amines, alkali metal or alkaline earth metal bases or with quaternary ammonium bases have good pre- and post-emergence-selective herbicidal and growth-regulating properties. In this formula, Rtiet18 is hydrogen, alkyl or alkoxy, X is an optionally substituted phenyl radical or a substituted naphthyl radical, YCtief1-Ctief3-alkyl, Ctief1-CtiHalogenalkyl, Ctief1-ctief3-haloalkoxy.Ctief1-Ctief3-alkylthio, Ctief2-Ctief3-alkoxylalkyl , Halogen or a givenf. substituted aminogr. u. Z Sauerst. or sulfur. |
