Abstract
Official abstract text for this publication.
The invention relates to the use of a grape marc extract in order to stimulate the natural defenses of plants and to a method for stimulating the natural defenses of plants, which comprises the application on said plants of a composition comprising a grape marc extract.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of inducing natural defenses in a plant, comprising applying to said plant, prior to exposure of the plant to a pathogen, a composition comprising an elicitor, wherein the elicitor is grape marc extract that has not undergone composting, and wherein the method induces a hypersensitive response in the plant prior to exposure of the plant to a pathogen, wherein the plant is a tobacco plant, a tomato plant or corn, and wherein the quantity of grape marc extract is from 0.0625% to 0.25% (w/v). 2. The method of claim 1 , wherein the composition is an aqueous composition and it is applied by foliar spraying or by infiltration. 3. The method of claim 1 , wherein the extract includes more than 45% polyphenols by weight in relation to the dry weight of the extract. 4. The method of claim 1 , wherein the extract includes more than 70% polyphenols by weight in relation to the dry weight of the extract. 5. The method of claim 1 , wherein the extract includes more than 0.5% anthocyanins by weight in relation to the dry weight of the extract. 6. The method of claim 1 , wherein the extract includes more than 8% anthocyanins by weight in relation to the dry weight of the extract. 7. The method of claim 3 , wherein the composition comprises an aqueous/alcoholic extract of grape marc. 8. The method of claim 1 , wherein the composition is an aqueous mixture comprising grape marc extract corresponding to a concentration of from 0.1 g/L to 10 g/L dry weight of the extract. 9. A method of inducing natural defenses in a plant, comprising applying to said plant, prior to exposure of the plant to a pathogen, a composition comprising an elicitor, wherein the elicitor is grape marc extract that has not undergone composting, wherein the method induces a systemic acquired response in the plant prior to exposure of the plant to a pathogen, wherein the plant is a tobacco plant, a tomato plant or corn, and wherein the quantity of grape marc extract is from 0.0625% to 0.25% (w/v). 10. A method of inducing natural defenses in a plant comprising applying to said plant, prior to exposure of the plant to a pathogen, a composition comprising an elicitor, wherein i) the elicitor is grape marc extract that has not undergone composting; and ii) the composition is an aqueous mixture comprising grape marc extract corresponding to a concentration of from 0.1 g/L to 2.5 g/L dry weight of the extract; and wherein the method induces a hypersensitive response in a plant prior to exposure of the plant to a pathogen, wherein the plant is a tobacco plant, a tomato plant or corn, and wherein the quantity of grape marc extract is from 0.0625% to 0.25% (w/v). 11. A method of inducing natural defenses in a plant, comprising applying to said plant, prior to exposure of the plant to a pathogen, a composition comprising an elicitor, wherein the elicitor is grape marc extract that has not undergone composting, and wherein the method induces a hypersensitive response in the plant prior to exposure of the plant to a pathogen, wherein the plant is a tobacco plant, and wherein the quantity of grape marc extract is from 0.0625% to 0.25% (w/v).
