Abstract

A biostimulant concentrate includes purified water and a solubilizer, triacontanol, an array of brassinosteroids selected from the group consisting of brassinolide, brassinone, dilholide, homobrassinolide, and combinations thereof. The ratio of tricontanol to the array of brassinosteroids is between 3.33:1 on a w:w basis to 50:1 on a w:w basis in one embodiment of the invention. Preferably, the array of brassinosteroids concentration is between 40-70 ppm in the biostimulant concentrate and the triacontanol concentration is approximately 3000 mg/l. The brassinosteroid includes brassinolide having the chemical formula C₆₄H₁₂₄O₂₆. The dilholide has the chemical formula C₂₈H₄₆O₆. The brassinone has the chemical formula C₂₇H₄₆O₅. Preferably, the at least one brassinosteroid is selected from the group consisting essentially of brassinone, dilholide, and homobrassinolide.
