Sulfonamides of the formula n nwherein J is a substituted aryl group of defined structure; nR is H or a lower organic group; nA is a mono- or bicyclic heterocyclic group; nexhibit herbicidal activity. Some also show a plant growth nregulant action, n The novel compounds may be made by a variety of ntechniques, e.g. by reacting an arylamine JNH₂ with a sulnfonyl chloride ASO₂Cl. |
