1. A herbicidal composition comprising:

  • (i) a 2-(substituted benzoyl)-1,3-cyclohexanedione of formula (I) embedded imagewherein X represents a halogen atom;

    a straight- or branched-chain alkyl or alkoxy group containing up to six carbon atoms which is optionally substituted by one or more groups —

    OR1 or one or more halogen atoms;

    or a group selected from nitro, cyano, —

    CO2R2, —

    S(O)mR1, —

    O(CH2)rOR1, —

    COR2, —

    NR2R3, —

    SO2NR2R3, —

    CONR2R3, —

    CSNR2R3 and —

    OSO2R4;

    R1 represents a straight- or branched-chain alkyl group containing up to six carbon atoms which is optionally substituted by one or more halogen atoms;

    R2 and R3 each independently represents a hydrogen atom;

    or a straight- or branched-chain alkyl group containing up to six carbon atoms which is optionally substituted by one or more halogen atoms;

    R4 represents a straight-or branched-chain alkyl, alkenyl or alkynyl group containing up to six carbon atoms optionally substituted by one or more halogen atoms;

    or a cycloalkyl group containing from three to six carbon atoms;

    each Z independently represents halo, nitro, cyano, S(O)mR5, OS(O)mR5 (C1-C6)-alkyl, (C1-C6)alkoxy, (C1-C6)haloalkyl, (C1-C6)haloalkoxy, carboxy, (C1-C6)-alkylcarbonyloxy, (C1-C6)alkoxycarbonyl, (C1-C6)alkylcarbonyl, amino, (C1-C6)-alkylamino, (C1-C6)dialkylamino having independently the stated number of carbon atoms in each alkyl group, (C1-C6)alkylcarbonylamino, (C1-C6)-alkoxycarbonylamino, (C1-C6)alkylaminocarbonylamino, (C1-C6)-dialkylaminocarbonylamino having independently the stated number of carbon atoms in each alkyl group, (C1-C6)alkoxycarbonyloxy, (C1-C6)-alkylaminocarbonyloxy, (C1-C6)dialkylcarbonyloxy, phenylcarbonyl, substituted phenylcarbonyl, phenylcarbonyloxy, substituted phenylcarbonyloxy, phenylcarbonylamino, substituted phenylcarbonylamino, phenoxy or substituted phenoxy;

    R5 represents cyano, —

    COR6, —

    CO2R6 or —

    S(O)mR7;

    R6 represents hydrogen or straight- or branched-chain alkyl group containing up to six carbon atoms;

    R7 represents (C1-C6)alkyl, (C1-C6)haloalkyl, (C1-C6)cyanoalkyl, (C3-C8)-cycloalkyl optionally substituted with halogen, cyano or (C1-C4)alkyl;

    or phenyl optionally substituted with one to three of the same or different halogen, nitro, cyano, (C1-C4)haloalkyl, (C1-C4)alkyl, (C1-C4)alkoxy or —

    S(O)mR8;

    R8 represents (C1-C4)alkyl;

    each Q independently represents (C1-C4)alkyl or —

    CO2R9 wherein R9 is (C1-C4)-alkyl;

    m is zero, one or two;

    n is zero or an integer from one to four;

    r is one, two or three; and

    p is zero or an integer from one to six; and

    an organic phosphate, phosphonate or phosphinate adjuvant at a concentration of less than 0.5% v/v when added to a spray tank as a tank mix additive or when co-formulated with a herbicide to produce a spray tank concentration of less than 0.5% v/v.
