This is a continuation in part application derived from our copending application Ser. No. 837,977 (filing date Mar. 10, 1986). 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, R is a C.sub.1 -C.sub.4 nitroalkyl group, a substituted C.sub.1 -C.sub.4 alkylthio group or C.sub.1 -C.sub.4 alkoxy group, an unsubstituted or substituted C.sub.3 -C.sub.4 alkenylthio or C.sub.3 -C.sub.4 alkynylthio group, the hydroxyamino group, a C.sub.1 -C.sub.4 alkoxyamino, C.sub.3 -C.sub.4 alkenyloxyamino or C.sub.3 -C.sub.4 alkynyloxyamino group, a --PO(C.sub.1 -C.sub.4 alkyl).sub.2 or --PO(CH.sub.3)OC.sub.1 -C.sub.4 -alkyl radical or an unsubstituted or substituted hydrazino radical.
