Abstract:
A substituted 2-phenylpyridine of formula (I), where Ar is a radical (A) or (B) and where the ring R is a fused heterocyclic ring which, together with the phenyl ring, forms one of the following bicyclic rings (a) to (l) and the N-oxides of (I) and the agriculturally utilizable salts of (I) if these exist. Use: herbicides, desiccation/defoliation of plants.
