Sulfonamides of the formulan wherein J is a substituted aryl group of defined structure;n R is H or a lower organic group; A is a mono- or bicyclic heterocyclic group; exhibit herbicidal activity. Some also show a plant growth regulant action. n The novel compounds may be made by a variety of techniques, e.g. by reacting an arylamine JNH 2 with a sulfonyl chloride ASO 2 Cl. |
