This method for cultivating cotton comprises treating seedlings at least once with a plant activator containing an exogenous elicitor and an endogenous elicitor. ## Claims ### Claim 1 A method for cultivating cotton, wherein the method comprises applying a plant-vitalizing agent comprising an exogenous elicitor and an endogenous elicitor at least once to a seedling of the plant. ### Claim 2 (depends on 1) The method for cultivating cotton according to claim 1, wherein the method comprises applying a plant-vitalizing agent to a seedling of the plant at least once at 2 to days after germination. ### Claim 3 (depends on 1) The method for cultivating cotton according to claim 1, wherein the method comprises applying a plant-vitalizing agent to a plant body at least once after the seedling stage. ### Claim 4 (depends on 1) The method for cultivating cotton according to claim 1, wherein the exogenous elicitor is a chitin oligosaccharide, and the endogenous elicitor is at least one type of oligosaccharide selected from among cellooligosaccharides and xylooligosaccharides. ### Claim 5 (depends on 1) The method for cultivating cotton according to claim 1, wherein the mass ratio of the exogenous elicitor with respect to the endogenous elicitor in the plant-vitalizing agent is 0.1 to 5. ### Claim 6 (depends on 1) The method for cultivating cotton according to claim 1, which comprises a xylooligosaccharide as the endogenous elicitor. ### Claim 7 (depends on 6) The method for cultivating cotton according to claim 6, which comprises both a cellooligosaccharide and a xylooligosaccharide as the endogenous elicitor. ### Claim 8 (depends on 7) The method for cultivating cotton according to claim 7, wherein the mass ratio of the cellooligosaccharide with respect to the xylooligosaccharide in the plant-vitalizing agent is 0.2 to 5. ### Claim 9 (depends on 1) The method for cultivating cotton according to claim 1, which comprises applying the plant-vitalizing agent to a plant at a concentration so that the total content of the exogenous elicitor and the endogenous elicitor is 0.1 to 500 ppm by mass. ### Claim 10 (depends on 1) The method for cultivating cotton according to claim 1, which comprises applying the plant-vitalizing agent to a plant by foliar application. ### Claim 11 (depends on 1) The method for cultivating cotton according to claim 1, wherein the cotton is of the species hirsutum. ### Claim 12 A plant-vitalizing agent comprising an exogenous elicitor and an endogenous elicitor, to be used for cultivation of cotton, which is applied at least one time to a seedling of the plant. ### Claim 13 (depends on 12) The plant-vitalizing agent according to claim 12, which is applied at least once to the seedling 2 to 15 days after germination. ### Claim 14 (depends on 12) The plant-vitalizing agent according to claim 12, which is applied at least once to the plant body after the seedling stage. ### Claim 15 (depends on 12) The plant-vitalizing agent according to claim 12, wherein the exogenous elicitor is a chitin oligosaccharide, and the endogenous elicitor is at least one type of oligosaccharide selected from among cellooligosaccharides and xylooligosaccharides. ### Claim 16 (depends on 12) The plant-vitalizing agent according to claim 12, wherein the mass ratio of the exogenous elicitor with respect to the endogenous elicitor in the plant-vitalizing agent is 0.1 to 5. ### Claim 17 (depends on 12) The plant-vitalizing agent according to claim 12, which comprises a xylooligosaccharide as the endogenous elicitor. ### Claim 18 (depends on 17) The plant-vitalizing agent according to claim 17, which comprises both a cellooligosaccharide and a xylooligosaccharide as the endogenous elicitor. ### Claim 19 (depends on 18) The plant-vitalizing agent according to claim 18, wherein the mass ratio of the cellooligosaccharide with respect to the xylooligosaccharide in the plant-vitalizing agent is 0.2 to 5. ### Claim 20 (depends on 12) The plant-vitalizing agent according to claim 12, which is applied to a plant at a concentration so that the total content of the exogenous elicitor and the endogenous elicitor is 0.1 to 500 ppm by mass. ### Claim 21 (depends on 12) The plant-vitalizing agent according to claim 12, which is applied to a plant by foliar application. ### Claim 22 (depends on 12) The plant-vitalizing agent according to claim 12, wherein the cotton is of the species hirsutum.
