Method of regulating plant growth

Abstract

Abstract SEMICARBAZIDES, ESPECIALLY THE TETRAALKYLATED THIOSEMICARBAZIDES AND BIURET DERIVATIVES, ESPECIALLY THE MONOAND DITHIOBIURET DERIVATIVES HAVE DEMONSTRATED EFFECTIVE GROWTH REGULATING ACTIVITY. EXEMPLARY OR PREFERRED SEMICARBAZIDES ARE THOSE HAVING THE FORMULA: R1-N(-R2)-C(=Y)-N(-X)-N(-R4)-R3 WHERE R1 AND R4 EACH REPRESENT AND UNSUBSTITUTED OR SUBSTITUTED C1-C30 HYDROCARBYL GROUP, PREFEFERABLY C1-C10, AND X CAN BE EITHER HYDROGEN, SAID UNSUBSTITUTED OR SUBSTITUTED HYDROCARBYL GROUP, AND Y CAN BE O OR S. EXEMPLARY OF PREFERRED BIURET DERIVATIVES ARE THOSE HAVING THE FORMULA: R5-N(-R6)-C(=Y)-N(-N(-R9)-R10)-C(=Y)-N(-R7)-R8 WHERE R5-R10 CAN BE H, UNSUBSTITUTED OR SUBSTITUTED C1C30 HYDROCARBYL GROUP, PREFERABLY C1-C10, AND Y CAN BE O ORS, AND COMBINATIONS THEREOF. TYPICAL R1-R10 HYDROCARBYL GROUPS INCLUDE: (1) SATURATED OR UNSATURATED, ACYCLIC OR CYCLIC, ALIPHATICS SUCH AS, E.G,M ETHYL, PROPARGYL, CYYCLOHEXY, CYCLOHEXENYL, ETC., AND (2) AROMATIC OR HETEROAROMATIC RADICALS, SUCH AS PHENYL, PYRIDYL, ETC.
