Abstract
Abstract A plant growth stimulator formulation including a substantially water-soluble concentrate solution of 1-triacontanol, a polar organic solvent, and metal ions having a valence of +2 or more. Metal ions disclosed in the present invention markedly increase the growth-stimulating effect of 1-triacontanol when applied to plant life resulting in crop yield increases which may be as high as 50 to 100% over controls. The formulations are effective on all plant life tested, including field corn, soybeans, wheat and grains, vegetables, and other plant life. In addition, additive effects are noted in successive generations of plant life to which the formulations are applied.
