Abstract
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.
Claims11
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).
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).
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).
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).
