    • New herbicidal picolinamide derivatives are described with general formula (I), in which Z represents an oxygen or sulphur atom, R and R each independently represents a hydrogen atom or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, alkaryl, hydroxy, alkoxy, alkenyloxy, alkynyloxy, alkylcarbonyl, amino, mono- or di-alkylamino, alkoxycarbonylamino, arylamino, arylalkylamino or dialkylcarbamoyl group, or together represent an alkylene chain which is optionally interrupted by an oxygen or sulphur atom or by a group -NR- in which R represents a hydrogen atom or an alkyl group, R or each R independently represents a halogen atom or an alkyl or haloalkyl group, R , R and R each independently represents a hydrogen or halogen atom, an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkylalkyl, aryl, aralkyl, alkaryl, alkoxy, amino, mono- or di-alkylamino, alkoxycarbonylamino, arylamino, dialkylcarbamoyl, acyl or acylamido group or a cyano group, with the proviso that R and R do not represent an acyl, acylamido or cyano group, and n represents 0, 1, 2 or 3. The invention further relates to the preparation of the above mentioned picolinamides, intermediates prepared during the synthesis of these compounds, compositions containing the compounds and their use as herbicides for the control of undesired plant growth.
