PURPOSE:To provide the solid composition comprising a powdery substance alone or its mixture with a water-soluble fertilizer component and/or a water-soluble saccharide, etc., and capable of easily deriving the slightly water-soluble rutin into easily applicable formulations, the powdery substance being obtained by drying a rutin-boron complex and being stable for a long period. CONSTITUTION:A rutin-baron complex is formed from rutin and boron. Dry rutin-boron complex powder obtained by removing water from the complex has sufficiently large water solubility. The powdered rutin-boron complex is used as an active ingredient to obtain a solid composition for the growth stimulation and growth control of a plant. The composition is mixed with a water-soluble fertilizer component, a water-soluble saccharide, and, if necessary, further auxiliary agents such as a water-soluble salt and a powdery surfactant, and subsequently formed by a conventional grinding means and a conventional molding means into formulations. The fertilizer component includes urea, ammonium sulfate, potassium phosphate, borax, manganese sulfate, and magnesium sulfate, and the saccharide includes dextrin, lactose, fructose, and sucrose. The water-soluble salt includes salt, mirabilite, and sodium carbonate. |
