Abstract

N-[(1,3,5-Triazin-2-yl)-aminocarbonyl]-benzenesulfonamide of the general formula ##STR1## where R¹ is methyl or ethyl, R² is halogen, C₁ -C₃ -alkylsulfonyl, trifluoromethyl or 2-methoxyethoxy and R³ is hydrogen, methyl, ethyl, methoxy, ethoxy, fluorine or chlorine, and their agriculturally useful salts, processes for their preparation and their use.

Claims

1. An N-((1,3,5-triazin-2-yl)-aminocarbonyl)benzenesulfonamide of the formula I ##STR23## where R² is methyl, R² is chlorine and R³ is hydrogen, or its agriculturally useful salts.

2. A herbicidal composition containing a herbicidally effective amount of N-((1,3,5-triazin-2-yl)-aminocarbonyl)-benzenesulfonamide of the formula I as defined in claim 1 or its salt and conventional carriers.

3. A method for controlling undesirable plant growth, wherein a herbicidal amount of an N-[(1,3,5-triazin-2-yl)-amminocarbonyl]-benzenesulfonamide of the formula I as defined in claim 1 or of one of its salts is allowed to act on the plants and/or their habitat.
