Herbicidally active substituted 5-acylamino-1-phenylpyrazoles of the formula ##STR1## in which R.sup.1 represents cyano, alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkenylaminocarbonyl or alkinylaminocarbonyl, R.sup.2 represents hydrogen, alkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, alkoxyalkyl, alkylthioalkyl, halogenoalkyl or optionally substituted aryl and R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbonyl or a radical --(X).sub.n --R.sup.8, wherein X represents oxygen, sulphur, sulphinyl or sulphonyl, n represents 0 or 1 and R.sup.8 represents halogenoalkyl, with the proviso that at least one of the radicals R.sup.3, R.sup.4, R.sup.5, R.sup.6 or R.sup.7 represents a radical --(X).sub.n --R.sup.8, but R.sup.1 does not represent cyano if R.sup.5 represents trifluoromethyl. Many of the intermediates are novel.
