ABSTRACT 1,2,3-Thiadiazol-5-yl-urea derivatives having a plant growth-regulating and defoliating action and their manfacture and use Novel 1,2,3-thiadiazol-5-yl-urea derivatives of the general formula I Image (I) (in which R1 represents aromatic hydrocarbon optionally mono-, di- or polysubstituted by Hal and/or Cl-C6-alkyl and/or Cl-C6-alkoxy and/or -NO2 and/or -CF3; and R2 re- presents E, monovalent metal equivalent, optionally sub- stituted Cl-C6-alkyl, C3-C6-alkenyl or -alkynyl, or -CO-R3 in which R3 represents H, optionally substituted Cl-C10-alkyl, C2-C6-alkenyl or -alkynyl, optionally Cl-C6-akyl-substituted C3-C8 cycloaliphatic hydrocarbon, aromatic hydrocarbon optionally mono-, di- or poly- substituted by Hal and/or Cl-C6-alkyl and/or Cl-C6- alkoxy and/or -NO2 and/or -CF3, optionally substituted heterocyclic hydrocarbon, Cl-C6-alkoxy, C3-C6-alkenyloxy or -alkynyloxy, optionally substituted aryloxy or aryl- thio, Cl-C4-alkylthio, or -NR4R5 in which R4 and R5 each represents H, Cl-C6-alkyl, or aromatic hydrocarbon optionally mono-, di- or polysubstituted by Hal and/or Cl-C6-alkyl and/or Cl-C6-alkoxy and/or -NO2 and/or -CF3) and their manufacture. The novel compounds have a plant growth-regulating and defoliating action, and accordingly may be made up with suitable carriers into plant growth-regulating and defoliating preparation and may be used for treating living plants and areas of land.
