The invention also relates to a nozzle for implementing the method. ## Claims ### Claim 1 A method for spraying a mixture comprising at least a first liquid in the form of a liquid preparation of water-soluble or water-swellable polymers and at least a second liquid, wherein said method comprises implementing a nozzle for simultaneously spraying at least the first liquid and the second liquid, the nozzle including: a body provided with a first chamber within which the first liquid flows and a second chamber within which the second liquid flows, each of the two chambers having a through-hole on the outside of the body, wherein the first chamber and the second chamber form a truncated cone shape having a tapered portion upstream of the through-holes, and wherein within the truncated cone shape, the first chamber and the second chamber are positioned concentrically in relation to one another, such that the first liquid and the second liquid flow concentrically relative to one another as they approach the through-holes, and a deflector secured to the body arranged downstream from at least one of the through-holes, in the direction of flow of the first and second liquids, said deflector being capable of modifying the direction of flow of the first and second liquids, wherein: the through-holes are aligned on the same plane on the outside of the body and are positioned concentrically in relation to one another such that the first and second liquids mix at the latest when they come into contact with the deflector; and the deflector assumes the form of a cone of revolution wherein the apex thereof is oriented towards the through-holes and wherein the axis of the deflector is combined with the axis of said holes. ### Claim 2 (depends on 1) The method for spraying according to claim 1, wherein the axis of one of the through-holes is positioned in the longitudinal direction of the body. ### Claim 3 (depends on 2) The method for spraying according to claim 2, wherein the deflector is positioned downstream from the through-hole having the axis that is positioned in the longitudinal direction of the body. ### Claim 4 (depends on 1) The method for spraying according to claim 1, wherein the second liquid is aqueous or organic or a mixture of the two. ### Claim 5 (depends on 1) The method for spraying according to claim 1, wherein the second liquid assumes the form of a water in oil emulsion or the form of an aqueous dispersion of particles. ### Claim 6 (depends on 1) The method for spraying according to claim 1, wherein the second liquid contains at least one substance of agronomic interest or at least one substance making it possible to improve the development or the growth of plant material. ### Claim 7 (depends on 1) The method for spraying according to claim 1, wherein the second liquid contains at least one cross-linking agent. ### Claim 8 (depends on 1) The method for spraying according to claim 1, wherein the first liquid comprises an acrylamide copolymer. ### Claim 9 (depends on 1) The method for spraying according to claim 1, wherein the weight content of polymer in the first liquid is between 0.01% and 75%. ### Claim 10 (depends on 1) The method for spraying according to claim 1, wherein the method is implemented in a fields of agriculture. ### Claim 11 (depends on 9) The method for spraying according to claim 9, wherein the weight content of polymer in the first liquid is between 5 and 60%. ### Claim 12 (depends on 9) The method for spraying according to claim 9, wherein the weight content of polymer in the first liquid is between 10 and 50%. ### Claim 13 (depends on 1) The method for spraying according to claim 1, wherein the method is performed in order to limit soil erosion, treat rainwater or wastewater, as part of a paper making process, or during mining extraction. ### Claim 14 (depends on 1) The method for spraying according to claim 1, wherein: the axes of the through-holes are secant such that the first and second liquids mix before they come into contact with the deflector; and/or the axis of one of the through-holes is positioned in the longitudinal direction of the body, and the deflector is positioned downstream from the hole having the axis that is positioned in the longitudinal direction of the body. ### Claim 15 (depends on 1) The method for spraying according to claim 1, wherein chambers present in the body consist of the first chamber and the second chamber.
