ABSTRACT Herbicidally active novel substituted 5-acylamino-1-phenylpyrazoles of the formula in which R1 represents cyano, alkoxycarbonyl, alkenyloxy-carbonyl, alkinyloxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkenylaminocarbonyl or alkinylaminocarbonyl, R2 represents hydrogen, alkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, alkoxyalkyl, alkylthioalkyl, halogenoalkyl or optionally sub-stituted aryl and R3, R4, R5, R6 and R7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbon-yl or a radical (X)n-R8, wherein X represents oxygen, sulphur, sulphinyl or sul-phonyl, n represents 0 or 1 and R8 represents halogenoalkyl, with the proviso that at least one of the radicals R3, R4, R5, R6 or R7 represents a radical -(X)n-R8, but R1 does not represent cyano if R5 represents tri-fluoromethyl. Many of the intermediates are also novel. |
