N-Phenylpyrazole derivatives of the formula: STR1 (wherein each of R5 and R6 represents a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical, or a fluorine, chlorine or bromine atom, each of R7, R8 and R9 represents a hydrogen atom, a C1 -C4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical or a fluorine, chlorine or bromine atom, or R5, R7, R8 and R9 each represents a hydrogen atom and R6 represents a trifluoromethoxy or trifluoromethyl radical, and R10 represents a cyano radical or substituted carbamoyl radical --CONHR11, wherein R11 represents a methyl or ethyl radical) have been found to possess useful herbicidal properties. All such N-phenylpyrazole derivatives with the exception of 5-amino-4-cyano-1-(2,4-dichlorophenyl)pyrazole and 5-amino-4-cyano-1-(4-chloro-2-methylphenyl)pyrazole are new compounds. Herbicidal compositions containing such N-phenylpyrazole derivatives are described and also processes for the preparation of the new compounds.
