The invention is a novel class of phthalimido derivatives represented by a formula: <IMAGE> wherein W is hydrogen or alkyl C1-C4; X and X' each represent hydrogen, halogen, alkyl C1-C4, CF3, alkoxy(C1-C4), benzyloxy, di(C1-C4)alkylamino, C1C4 alkylthio, hydroxy, C1-C4 alkylsulfonyl, alkanoylamino C1-C4 or nitro; Y is -COOR3, -CONHR8, -CONR3 R4, -CONHN(R5)2, -CONHN<+>(R6)3 . halide<->, -CN or -CCR7 with the proviso that at least one of X and X' is a substituent other than hydrogen; R1 and R2 each represent alkyl C1-C4 or when taken together with the carbon to which they are attached form cycloalkyl C4-C11 optionally substituted with methyl; R3 and R4 each represent hydrogen or alkyl C1-C4; R5 and R6 each represent alkyl C1-C2; R7 is halogen and R8 is -CH3 or <IMAGE> where Z and Z' are hydrogen, alkyl C1-C2, halogen, -CF3 or -OCH3, - - - is a single or double bond with the proviso that there be only 0 or 1 double bond in the ring and a method for regulating the growth of plants with these compounds and with compounds having the above structure wherein X and X' each represent hydrogen.
