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-methoxycarbonylbenzenesulf onamide or N-[(4,6-dimethoxy-1,3,5-triazin-2-yl)aminocarbonyl]-2-methoxycarbonylbenze nesulfonamide; are useful for the regulation of plant growth and as pre-emergence and post-emergence herbicides.
2-位置被羧基基团、酯、
硫酯或其酰胺取代的N-(杂环
氨基甲酰)芳基磺酰胺;例如,N-[(4,6-二
甲基嘧啶-2-基)
氨基甲酰]-2-甲氧基羧酰基苯磺酰胺或N-[(4,6-二甲氧基-
1,3,5-三嗪-2-基)
氨基甲酰]-2-甲氧基羧酰基苯磺酰胺;对于植物生长的调节以及作为前出和后出
除草剂是有用的。
