Sulfonamide derivatives of the formulan wherein Q is O, S orn n R 1 is optionally substituted pyrimidyl or triazinyl; R 2 is H, halogen, alkyl, NO 2 , SO 2 CH 3 , OCH 3 , SCH 3 , CF 3 , N(CH 3 ) 2 , NH, or CN; R 3 is H, halogen or CH,; R 4 is H or CH,; R 5 is H, CH 3 or OCH,; R 6 is H, alkyl, cyanoalkyl or allyl; and R is selected from a variety of acyclic and cyclic organic groups: and agriculturally suitable salts thereof; exhibit activity as herbicides and for regulating plant growth. They may be formulated into compositions in conventional manner. n The compounds may be made e.g. by reacting the appropriate 2-substituted benzene sulfonyl isocyanate or isothiocyanate with the appropriate aminopyrimidine or aminotriazine. |
