Abstract
Abstract Herbicidal N - (heterocyclicaminocarbonyl)- sulfonamides, and preparation and use thereof, having the general formula wherein R is an aromatic organic group, W is oxygen or sulphur and X and Y are hydrogen, chlorine, bromine, methyl, methoxy or ethoxy. The compounds may be made by reacting 4-aminopyrimidine with an isocyanate or isothiocyanate. They can be formulated for agricultural use with a surface active agent and/or a solid or liquid diluent, and can be used pre- or post-emergence for controlling weeds or for regulating plant growth.
