Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonamides, e.g., 5,7-dimethyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulfonamide and their agriculturally acceptable salts are prepared. These compounds and compositions containing them are useful for the control of unwanted vegetation. Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonyl chlorides and substituted anilines and their use as intermediates are also described.
