Abstract
N-Pyrimidin-4-yl-N'-sulfonylureas of the formula I and the basic addition salts thereof have herbicidal properties and properties for regulating, especially inhibiting, plant growth: ##STR1## the symbols in this formula having the following meanings: Q is halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, nitro, amino, lower alkyl or dialkylamino, lower alkoxycarbonyl, formyl, lower alkoxyalkyl, lower alkoxyalkoxy, lower alkylthio, lower alkylsulfinyl or alkylsulfonyl, C.sub.1 -C.sub.4 -alkenyl or C.sub.1 -C.sub.4 -alkynyl, PA0 R.sub.1 is hydrogen, halogen, nitro, a ketal radical, a carbonyl radical substituted by allyl, haloalkyl, alkoxy or cycloalkyl, or is an oxime radical, a lower alkoxy, lower alkylthio, lower alkyl, lower alkylsulfinyl or sulfonyl group, PA0 R.sub.2 and R.sub.3 independently of one another are each hydrogen, halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, lower alkylthio, lower alkoxyalkyl, lower alkoxyalkoxy, amino, lower alkyl- or dialkylamino or cyclopropyl, and R.sub.2 and Q together can also form a 2-4-membered carbon chain, which is optionally interrupted by an oxygen or sulfur atom or by the group --NR.sub.5 -…
