A 1-arylpyrazole of the formula (I) ##STR1## in which R.sup.1 stands for hydrogen or nitro, R.sup.2 stands for hydrogen, for a radical ##STR2## or a radical --S(O).sub.n --R.sup.5, R.sup.3 stands for alkyl, for a radical ##STR3## or for a radical --S(O).sub.n --R.sup.5, and, in addition, in the case where R.sup.2 stands for a radical --SO.sub.2 --R.sup.5, R.sup.3 alternatively stands for an inorganic or organic cation bonded in the manner of a salt, where R.sup.4 stands for hydrogen, alkyl, alkenyl, alkinyl, monohalogenoalkyl, alkoxyalkyl, halogenoalkoxyalkyl, alkylthioalkyl, alkoxy, alkylthio, alkylsulphonylalkyl, alkylsulphinylalkyl, alkylamino, dialkylamino, optionally substituted cycloalkyl, optionally substituted aryl, optionally substituted aryloxy, optionally substituted arylthio, or for optionally substituted arylamino, X stands for oxygen or sulphur, R.sup.5 stands for alkyl, halogenoalkyl or for optionally substituted aryl, n stands for a number 0, 1 or 2, and Ar stands for one of the radicals ##STR4## wherein A.sup.1 stands for hydrogen, fluorine or chlorine, A.sup.2 stands for fluorine or chlorine and A.sup.3 stands for hydrogen or fluorine, but excluding the compounds 5-ethoxycarbonylamino-1-(2,3-dichloro-4-trifluoromethylphenyl)-4-nitro- pyrazol and 5-acetamido-1-2,5-difluoro-4-trifluoromethylphenyl)-pyrazole. Such 1-arylpyrazoles are useful as herbicides and as plant growth-regulating agents.
