A plant growth regulator containing as an active ingredient one or more compounds represented by the formula ##STR1## wherein R, X, Y and Z are defined in the specification is disclosed. The plant growth regulator is effective for a wide variety of plants, particularly for grassy plants. In addition to such activity, the regulator of this invention acts on plants to thicken the foliage and to aid health growth without causing substantial phytotoxicity.

Plant growth regulator

Isonicotinanilide derivatives of the formula ##STR1## (wherein R.sub.1 is a hydrogen atom or a lower alkyl group; X is a halogen atom or methyl; n is an integer of from 0 to 2; R.sub.2 is phenyl, halo-substituted phenyl or a lower alkyl group; and Q is ##STR2## provided that Q is ##STR3## or --CH.sub.2 --when R.sub.2 is phenyl or halo-substituted phenyl, and Q is ##STR4## when R.sub.2 is a lower alkyl group) a process for preparing the same and a plant growth regulator containing the same are disclosed. The derivatives of the formula above have good activity for regulating the growth of various plants, especially of grassy plants.
