Herbicidally active novel substituted 5-acylamino-1-phenylpyrazoles of the formula <IMAGE> in which R1 represents cyano, alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkenylaminocarbonyl or alkinylaminocarbonyl, R2 represents hydrogen, alkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, alkoxyalkyl, alkylthioalkyl, halogenoalkyl or optionally substituted aryl and R3, R4, R5, R6 and R7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbonyl or a radical -R8, wherein R8 represents halogenoalkyl, with the proviso that at least one of the radicals R3, R4, R5, R6 or R7 represents a radical -R8, but R1 does not represent cyano if R5 represents trifluoromethyl. Many of the intermediates are also novel.
