A herbicidal composition comprises ester, amide, aryl and heterocyclic derivatives of monic acid A, monic acid B, monic acid C, monic acid ketone and pseudomonic acid. Novel monic acid esters may be represented by the formula (mon)-CO-XR3 wherein (mon) is a residue of a monic acid compound, (mon)-COOH, X is O or S and R3 is an alkyl group substituted by a group -A-R11 wherein A is O or a group S(O)¿x?, and R?11¿ is an optionally substituted alkyl, alkenyl, alkynyl, phenyl, alkyl carbonyl, cycloalkyl or heterocyclyl group. |
