PURPOSE: To obtain a plant growth controlling agent having synergetic activity and capable of exhibiting strong plant growth controlling activity, e.g. bud growth-stimulating effect, cold resistance-stimulating effect and plant growth maturation-stimulating effect. CONSTITUTION: This plant growth controlling agent contains (A) an epoxycyclohexane derivative of formula I (R<1> is H, a 1-6C alkyl or a 3-6C cycloalkyl; R<2> and R<3> are each a lower alkyl or together form polymethylene which optionally substituted with an alkyl), e.g. 4,4- ethylenedioxy-1- 4-(hydroxycarbonyl)-1-hydroxy-3-methyl-3-buten-1-yl}-1,2-oxo-2,6,6- trimethylcyclohexane and (B) a brassiosteroid, preferably a compound of formula II (R<4> and R<5> are each a lower alkyl), e.g. (22R,23R,24S)-2α,3α- dipropionyloxy-22,23-epoxy-B-homo-7-oxa-5α-stigmastan-6-one, as active components. |
