HERBICIDE AND GROWTH-CONTROLLING COMPOSITIONS CONTAINING PYRIDINE-SULFONYL-UREAS AS ACTIVE COMPONENTS AND PROCESS FOR PRODUCING PYRIDINE-SULFONYL-UREAS |
摘要 |
Pyridinesulfonylureas of general formula: <CHEM> wherein J is a substituted pyridyl group; W is O or S; R is H or CH3; A is a mono- or bicyclic heterocyclic group, e.g. pyrimidinyl or triazinyl; and their agriculturally suitable salts show high activity as preemergence and postemergence herbicides. some also show a plant growth regulant effect. The novel compounds may be made e.g. by reacting an appropriate pyridine sulfonamide JSO2NH2 with an appropriate heterocyclic phenyl carbamate:- <CHEM> t |
