Abstract: The invention relates to new N-substituted amino propane sulfonic acid derivatives of the Formula I ##STR1## and salts and hydrates thereof, a process for the preparation thereof and plant growth regulating agents comprising the same whereinR.sup.1 and R.sup.2 may be identical or different and stand for hydrogen, halogen, lower alkyl or lower alkoxy andR stands for furyl; or lower alkyl or phenyl the two latter groups being optionally substituted by one or more halogeno atom(s).

Abstract: New substituted carbamoylimidazole derivatives of the general formula (I) ##STR1## have been prepared by reacting the appropriate substituted imidazole derivatives of the general formula (II) ##STR2## with isocyanate compounds of the general formula (III)R.sub.4 -- N .dbd. C .dbd. O (III).the new compounds of the general formula (I) are potent herbicides and fungicides.In the above formulaeR.sub.1 stands for hydrogen atom or methyl group,R.sub.2 and R.sub.3 each may represent a hydrogen atom or a nitro group, or R.sub.2 and R.sub.3 may form together a --CH.dbd.--CH--CH.dbd.CH--group, which forms a six-membered ring together with the adjacent carbon atoms of the imidazole ring, andR.sub.4 stands for a cyclohexyl, phenyl, chlorophenyl or dichlorophenyl group.
