Abstract

Abstract Plant growth regulant compounds represented by the formula: ##STR1## wherein, when n is 1, R is hydrogen, sodium, potassium, ammonium, substituted ammonium, straight or branched chain aliphatic hydrocarbyl or halo-lower alkyl and, when n is 2, R is calcium, magnesium or lower alkylene, R 1 , R 2 , R 3 and R 4 are hydrogen, straight or branched chain aliphatic lower hydrocarbyl, halo-lower alkyl, aryl or R 1 and R 2 together and R 3 and R 4 together are each a saturated ring containing from 3 to 8 carbon atoms, n is an integer from 1 to 2 and X is a number from 0 to 1; enantiomers and racemic mixtures. These compounds are useful as post-emergence and pre-emergence plant growth regulants and herbicides.
