<p>There is provided a method for selectively controlling the weed galium in cereal crops which comprises applying to the locus where control is desired a herbicidally effective amount of composition (I) wherein R is halogen, or lower alkyl; R1 is haloalkyl; X is hydrogen, halogen, alkyl, haloalkyl, alkoxy, or nitro; Y is hydrogen, halogen, alkyl, alkoxy, haloalkyl, halo lower alkylsulfinyl, or halo lower alkoxy; Q is -CH(R?2)C(R3)(R4)Q'; R2¿ is H or halogen; R3 is halogen; R4 is H or lower alkyl; Q' is COOH, COOZ, COOR?5, CON(R6)(R7¿), CN, CHO or C(O)R5; Z is a salt-forming group; R5 is alkyl, alkoxycarbonylalkyl, cycloalkyl, aryl, haloaryl, haloalkylaryl, or aralkyl, preferably benzyl; each of R?6 and R7¿ is, independently, hydrogen or a radical which is alkyl, cycloalkyl, alkenyl, alkynyl, alkoxy, phenyl, benzyl or SO¿2R?6 or is one of said radicals substituted by halogen, alkyl or cyano.</p> |
