N- ,6-DIMETHOXYPYRIMIDIN-2-YL AMINOCARBONYL -3- TRIFLUOROMETHYLPYRIDINE-2-SULFONAMIDE

摘要

N-[(4,6-Dimethoxypyrimidin-2-yl)aminocarbonyl]-3-trifluoromethylpyridi ne-2-sulfonamide or a salt thereof is disclosed. The compound of the invention is useful as a herbicide which has an extremely high herbicidal effect against a wide variety of weeds including strongly noxious weeds but which shows a high safety against tomato and turfs. A process for the production of N-[(4,6-dimethoxypyrimidin-2-yl)aminocarbonyl]-3-trifluoromethylpyridi ne-2-sulfonamide is also disclosed.
