ABSTRACT Novel 1,2,3-thiadiazol-5-yl-urea derivatives of the general formula I Image (I) (in which R1 represents H or Cl-C4-alkyl optionally in- terrupted by O and/or S, R2 represents Cl-C4-alkyl optionally interrupted by O and/or S, optionally alkyl-substituted cycloaliphatic hydrocarbon, aromatic hydrocarbon optionally substituted by one or more substituents selected from Hal, alkyl, alkylthio, alkoxy, -CF3 and -NO2, or optionally substituted heterocyclic hydrocarbon containing at least one hetero N, R3 represents H, optionally substituted Cl-C10-alkyl, C2-C8-alkenyl, optionally Cl-C6-alkyl-sub- stituted C3-C8-cycloaliphatic hydrocarbon, aromatic hydrocarbon optionally substituted by one or more sub- stituents selected from Hal, Cl-C6-alkyl, Cl-C6-alkoxy, -CF3 and -NO2, or optionally substituted heterocyclic hydrocarbon and X represents O or S) 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 preparations and may be used for treating living plants and areas of land.
