A herbicidal composition comprising a sulfonylurea derivative of formula (I) <CHEM> wherein Q is -CH=CH- or -S-, R is straight or branched C1-3 alkyl, and X is -OCH3 or -CH3, or an agriculturally acceptable salt thereof, and at least one co-herbicide selected from * imidazolinone herbicides, diphenyl ether herbicides, hydroxybenzonitrile herbicides, 2-(4-aryloxyphenoxy) alkanoic acid herbicides and oxime herbicides, carbamate and thiocarbamate herbicides, quaternary ammonium salt herbicides, triazole herbicides, phytohormone herbicides, including aryloxyalkanoic acid herbicides, arenecarboxylic acid herbicides, pyridinecarboxylic acid herbicides, and pyridyloxyacetic acid herbicides, 2, 6-dinitroaniline herbicides, amide herbicides, and anilide herbicides, the respective herbicidal constituents being present in amounts such that the compositions display selectivity of herbicidal action with respect to crops being treated pre- or post-emergent and exhibit synergistic effects when applied at herbicidally effective rates. |
