Novel compounds are disclosed which have utility as plant growth regulators. Use to produce growth regulators is specifically illustrated. The novel compounds of this invention are phthalimidoguanidines of the following general structural formulas: ##STR1## in which R, R.sup.1 and R.sup.5 are hydrogen, C.sub.1 to C.sub.5 alkyl, R.sup.2 and R.sup.3 are alike or unlike, one of which may be hydrogen but otherwise are substituents selected from C.sub.1 to C.sub.5 alkyl, alkenyl or alkynyl, branched or unbranched, C.sub.2 to C.sub.5 hydroxyalkyl or alkoxyalkyl, C.sub.3 to C.sub.5 cycloalkyl, furfuryl, pyridyl, benzyl, phenyl, C.sub.1 to C.sub.5 alkylphenyl, or --NR.sup.2 R.sup.3 together may be 2,5-dimethyl-1-pyrryl, 4-morpholinyl or 1-pyrrolidinyl, R.sup.4 is halogen, nitro, cyano, trifluoromethyl, C.sub.1 to C.sub.5 alkyl or acyl and n is zero, one or two.
