N-phenylpyrazole derivatives of formula: $ (8,) $ (where R12 represents a chlorine atom, R13 represents a hydrogen, or fluorine or chlorine atom, R14 represents a hydrogen or fluorine atom and R15 represents a hydrogen, fluorine or chlorine atom, provided that when R14 represents a fluorine atom, R15 represents a fluorine or chlorine atom, or R12, R13 and R15 each represent a fluorine atom and R14 represents a hydrogen or fluorine atom), which derivatives have useful herbicidal properties. Herbicidal compositions, methods for controlling weed growth and methods for preparing N-phenylpyrazole derivatives are also described, as well as the intermediates of formula: |
