Abstract
Abstract N-(heterocyclicaminocarbonyl)arylsulfonamides in which the aryl radical is substituted in the 2-position by a carboxy radical, ester, thioester, or amide thereof; e.g. N-[(4,6-dimethylpyrimidin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide or N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenzenesulfonamide; are useful for the regulation of plant growth and as pre-emergence and post-emergence herbicides.
