HERBICIDES

摘要

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-XR<3> wherein (mon) is a residue of a monic acid compound, (mon)-COOH, X is O or S and R<3> is an alkyl group substituted by a group -A-R<11> 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.
