Abstract
Herbicide N-[(pyrimidin-2-yl)aminocarbonyl] benzene sulphonamides of general formula I, wherein the substituents represent the following: R1 represents methyl or ethyl; R2 represents hydrogen or methyl; R3 represents optionally substituted alkyl; or a group ER6; in which E stands for O or S, and R6 represents optionally fluorine-susbtituted alkyl except difluoromethoxy or, if E represents O and simultaneously, R5 represents trifluoromethyl, can represent methyl sulphonyl, ethyl sulphonyl, trifluoromethyl sulphonyl; allyl sulphonyl, or propargyl sulphonyl; or NO2 or OH; or a dialkyl group, if R5 represents fluorine; or a C1-C2- alkyl sulphonyl group which can contain 1-3 halogen atoms; R4 represents hydrogen, methyl, ethyl, methoxy, ethoxy, fluorine, chlorine, methylthio, ethylthio, or C1-C2-halogen alkoxyl; R5 represents fluorine or trifluoromethyl, as well as their environmentally acceptable salts and process for their manufacture and their use.
