Novel method for regulating the growth of plants which method comprises applying to the plants or their habitat, effective amounts of heterocyclic compound of the formula ##STR1## in which R.sup.1 is alkyl or optionally substituted aryl, R.sup.2 is hydrogen, alkyl or optionally substituted aryl, R.sup.3 is hydrogen or the radical ##STR2## in which Y is oxygen or sulfur and R.sup.5 is alkyl, haloalkyl, alkoxyalkyl, aryloxyalkyl, which is optionally substituted in the aryloxy part, alkoxy, optionally substituted aryl, optionally substituted aryloxy, monoalkylamino, dialkylamino, alkenylamino, dialkenylamino, optionally substituted arylamino, a 5-membered to 7-membered heterocyclic ring, bonded via nitrogen, or the radical ##STR3## in which R.sup.6 is hydrogen or alkyl and R.sup.7 is hydrogen or alkyl, or R.sup.6 and R.sup.7, together with the adjacent nitrogen atom, are a 5-membered to 7-membered heterocyclic ring, R.sup.4 is cyano or the grouping --COR.sup.8 in which R.sup.8 is alkoxy or amino, and X is oxygen or sulfur.
