摘要	N-Phenylpyrazole derivatives of the formula:- (wherein each of R 5 and R 6 represents a C 1 -C 4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical, or a fluorine, chlorine or bromine atom, each of R', R' and R 9 represents a hydrogen atom, a C 1 -C 4 alkyl or alkoxy radical, a trifluoromethyl, trifluoromethoxy, nitro, cyano or primary amino radical or a fluorine, chlorine or bromine atom, or R 5 , R 7 , R' and R 9 each represents a hydrogen atom and R 6 represents a trifluoromethoxy or trifluoromethyl radical, and R 10 represents a cyano radical or substituted carbamoyl radical -CONHR", wherein R" 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 prepararation of the new compounds.
