Abstract
This continuation-in-part is directed to novel pyridine compounds of formula I below have good selective herbicidal properties pre- and postemergence and also influence or inhibit plant growth. The compounds are of formula I ##STR1## wherein each of X, Y and Z independently of one another is hydrogen or a C.sub.1 -C.sub.4 alkyl group, or two adjacent substituents together also form a saturated or unsaturated 3- or 4-membered alkylene chain or alkenyl chain, each of which chains may in turn by substituted by one to four C.sub.1 -C.sub.4 alkyl groups and R is a C.sub.1 -C.sub.4 nitroalkyl group.
