ABSTRACT "N-PHENYLPYRAZOLE DERIVATIVES" N-phenylpyrazole derivatives of the general formula:- IV (wherein R12 represents a chlorine atom, R13 represents a hydrogen, fluorine or chlorine atom,R14 represents a hydrogen or fluorine atom and R15 represents a hydrogen, fluorine or chlorine atom, with the proviso 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) possess useful herbicidal properties. Herbicidal compositions, methods for controlling the growth of weeds and processes for the preparation of the N-phenylpyrazole derivatives are described. . |
