<p>Compounds of the formula: <CHEM> wherein J is substituted amino or optionally substituted hydrazino; R is H or CH3; R2 is H or a variety of organic or inorganic substituents; W is O or S; A is a mono- or bicyclic heterocyclic group, e.g. pyrimidinyl or triazinyl; and their agriculturally suitable salts, exhibit herbicidal activity. Some also show a plant growth regulant effect. The novel compounds may be made by a variety of routes, e.g. by reacting an appropriate benzenesulfonyl isocyanate or isothiocyanate with the appropriate heterocyclic amine.</p> |
