Sulfonamide derivatives of the formula <CHEM> wherein Q is O, S or <CHEM> R1 is optionally substituted pyrimidyl or triazinyl; R2 is H, halogen, alkyl, NO2, SO2CH3, OCH3, SCH3, CF3, N(CH3)2, NH2 or CN; R3 is H, halogen or CH3; R4 is H or CH3; R5 is H, CH3 or OCH3; R6 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. The compounds may be made e.g. by reacting the appropriate 2-substituted benzene sulfonyl isocyanate or isothiocyanate with the appropriate aminopyrimidine or aminotriazine. |
