ABSTRACT:
New 1,2,3-thiadiazole-5-yl-urea derivatives as plant growth regulating agents are provided, including processes for producing and using these compounds. The new 1,2,3-thiadiazole-5-yl-urea derivatives have the formula ##STR1## in which R.sub.1 is an aromatic hydrocarbon group which may be substituted with one or more members of the group consisting of C.sub.1 -C.sub.6 -alkyl, halogen, C.sub.1 -C.sub.6 -alkoxy, nitro and trifluoromethyl and R.sub.2 is hydrogen, a monovalent metal or its metal equivalent, a substituted or unsubstituted C.sub.1 -C.sub.6 -alkyl, a C.sub.3 -C.sub.6 -alkenyl or alkinyl, a substituted or unsubstituted aryl- C.sub.1 -C.sub.2 -alkyl or the group aryl-C.sub.1 -C.sub.2 -alkyl ##STR2## wherein R.sub.3 is hydrogen, a substituted or unsubstituted C.sub.1 -C.sub.10 -alkyl, C.sub.2 -C.sub.6 -alkenyl, a C.sub.2 -C.sub.6 -alkenyl, an aryl-C.sub.1 -C.sub.2 -alkyl, a C.sub.3 -C.sub.8 -cycloaliphatic hydrocarbon group which may be substituted with one or more C.sub.1 -C.sub.6 -alkyl substituents, an aromatic hydrocarbon group which may be substituted with at least one of C.sub.1 -C.sub.6 -alkyl, halogen, C.sub.1 -C.sub.6 -alkoxy, nitro and trifluoromethyl, a substituted or unsubstituted heterocyclic hydrocarbon, C.sub.1 -C.sub.6 -alkoxy, C.sub.3 -C.sub.6 -alkenyl-or alkinyloxy, a substituted or unsubstituted aryloxy, and C.sub.1 -C.sub.4 -alkylthio or an arylthio or an amino group ##STR3## wherein R.sub.4 and R.sub.5 are each the same or different and are selected from the group consisting of hydrogen, C.sub.1 -C.sub.6 -alkyl, aryl or aryl substituted with one or more of the members selected from the group consisting of C.sub.1 -C.sub.6 -alkyl, halogen, C.sub.1 -C.sub.6 -alkoxy, nitro and trifluoromethyl.
