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 alkyl of from 1 to 20 carbon atoms, straight or branched chain alkenyl of from 1 to 20 carbon atoms, straight or branched chain alkynyl of from 1 to 20 carbon atoms or halo-lower alkyl and, when n is 2, R is calcium, magnesium or lower alkylene, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are hydrogen, straight or branched chain alkyl of from 1 to 7 carbon atoms, straight or branched chain alkenyl of from 1 to 7 carbon atoms, straight or branched chain alkynyl of from 1 to 7 carbon atoms, halo-lower alkyl, aryl or R.sub.1 and R.sub.2 together and R.sub.3 and R.sub.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.
