Patent number: 10081805Abstract: Bio-regulators from a group of quaternary ammonium moieties modify a gene expression in a plant to induce enhanced growth and robustness. Such bio-regulator may be applied to seeds through coating or encapsulating, to plants through root drenching, spraying and dusting. Bio-regulators may be duel-acting; causing beneficial modification to gene expressions in desirable plants while modifying gene expression in undesirable plants, making them more susceptible to herbicides. Bio-regulators are Ester Compounds, BMIA Compounds or related salts, BMIA Compounds or related salts of those compounds.Type: GrantFiled: October 10, 2016Date of Patent: September 25, 2018Assignee: KamTec, LLCInventors: Henry Yokoyama, James H. H. Chan, Paul S. Oyama, Loren J. Hov, Christopher Lee Petersen, David Vu, John A. Eastin

Patent number: 8999890Abstract: Bio-regulators from a group of quaternary ammonium moieties modify a gene expression in undesirable plants to inhibit growth and robustness and enhance the effectiveness of herbicides. Such bio-regulator may be applied to plants through seed treatments, root drenching, spraying and dusting, or to soil were desirable crops are planted or will be planted. Bio-regulators may be duel-acting; causing beneficial modification to gene expressions in desirable plants while modifying gene expression in undesirable plants, making them more susceptible to herbicides.

Patent number: 6239078Abstract: The present invention is directed to a new matter of composition in the form of chemical compounds and to a method for enhancing plant growth and the properties exhibited by plants treated with the compounds in accordance with this method. In particular, application of the compounds results in an increase in sugar content, essential oils and proteins along with an increase in total plant biomass. Fruits harvested from treated plants exhibit an accelerated biochemical and structural maturity. Citrus fruits typically show a reduced peel thickness and exhibit significant improvements in vitamin C, carotenoid, and essential oil contents. The methods of the present invention produce balanced improvements in the structural, biochemical, and sensory quality of Citrus fruits.Type: GrantFiled: February 8, 2000Date of Patent: May 29, 2001Assignees: Tropicana Products, Inc., The United States of America as represented by the Department of AgricultureInventors: Henry Yokoyama, James H. Keithly, Harold W. Gausman

Patent number: 5854178Abstract: Novel bioactive compounds which when applied to plants in bioregulatory amounts, enhance plant development responses, resulting in enhanced plant properties such as increased total biomass, increased yield, and increased plant quality. Some of the compounds increase the content of taxol and related taxanes in yew plants. One compound, 2-?diethylaminoethyl!-2-methylpropylether causes plants treated with the compound to have resistance to chewing insects. The compound 2-?diethylaminoethyl!-2-methyl-2-phenylpropylether causes plants treated with the compound to have resistance to sucking insects.Type: GrantFiled: July 3, 1997Date of Patent: December 29, 1998Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Henry Yokoyama, Harold W.

Patent number: 5324707Abstract: This invention is directed to a method for the in vitro application of bioregulator compounds. When applied to intact plants in bioregulatory amounts, the compounds enhance important plant properties such as sugar content, essential oils, vitamins, proteins, and an overall increase in total biomass. The treated plants exhibit accelerated growth, accelerated fruit ripening, improved color scores of juice products and an accelerated maturation. The bioregulator compounds which comprise the invention enhance these plant properties when applied individually to plants. It has also been discovered that the application of mixtures of such compounds effect a greater than additive result and enhance the aforementioned plant properties to an unpredicted and unexpected degree when compared to known bioregulator agents. The present application discloses the usage of plant bioregulator agents in an in vitro environment.Type: GrantFiled: September 30, 1992Date of Patent: June 28, 1994Assignees: Tropicana Products, Inc., The United States of America as represented by the Secretary of AgricultureInventors: Henry Yokoyama, James H.

Patent number: 5304529Abstract: This invention is directed to a synergistic mixture of bioregulator compounds and a method of their use. Mixtures of these compounds, when applied to plants in bioregulatory amounts, enhance important plant properties such as sugar content, essential oils, vitamin C, proteins, and an overall increase in total plant biomass. The treated plants exhibit accelerated ripening, improved color scores of juice products, and an accelerated maturation. The bioregulator compounds which comprise the invention enhance these plant properties when applied individually to plants, but the application of mixtures of such compounds effect a greater than additive result and enhance the aforementioned plant properties to an unpredicted and unexpected degree when compared to known bioregulator agents.Type: GrantFiled: September 30, 1992Date of Patent: April 19, 1994Assignees: Tropicana Products, Inc., The United States of America as represented by the Secretary of AgricultureInventors: Henry Yokoyama, James H.
