A novel class of N-(arylthiocarbamoyl)-2- amino-1H-isoindole-1,3-(2H) diones which are useful as plant growth regulators have the general structural formula:
in which
R1 is; C1 to C4 alkyl, nitro or halo and n is zero or an integer from 1 to 4
R2 and R3 are; H or C to C. alkyl, or benzyl and
Ar is; adamantyl, C3 to C4 alkyl or alkenyl, benzyl, halobenzyl, naphthyl, phenyl or phenyl bearing thereon from one to three of the substituents: cyano, benzyloxy, nitro, bromo, chloro, trifluoromethyl and C1 to C4 alkyl, alkenyl, alkoxy, alkylthio and alkyl-substituted amino.
