  • the present invention described herein is a coating for seeds comprising at least one polymer that is applied in liquid form to the surface of the seeds. After application, the coating is dried and forms an insoluble coating to the seed surface. The coating becomes tacky when subjected to moisture thus improving the adherence of seeds to landscape ground surfaces.
  • a horticulture system comprising the coated seeds and a container for distributing the coated seeds, and optionally at least one other horticulture material, is also included as part of the invention described herein.
  • “Horticulture material” as used herein is intended to include seeds (such as turf seeds), mulch (such as wood mulch, coconut wood fibers, and the like, and mixtures thereof), fertilizer material (such as fertilizer pellets), and the like, and mixtures thereof.
  • Suitable polymers comprising the coating include polyvinyl acetate, polyvinyl alcohol, sodium polyacrylate, starch, pectin, carboxymethylcellulose, and combinations thereof.
  • the coating described herein may be applied to other materials useful in horticulture applications.
  • the coating may be applied to wood mulch and/or fertilizer pellets. These materials are often combined with seeds to aid in the germination process.
  • the coating of the present invention may be applied to seeds, mulch (such as wood mulch, coconut fiber, and the like), fertilizer pellets, and combinations thereof.
  • Descriptions of exemplary suitable horticulture materials that may be coating according to the present invention are provided in USPNs 8,024,890 and 8,429,849; in US Patent Application Publication Nos. 2006/0047068, 2010/0093535, and 2012/0277099; and in Canadian Patent No. 2839535.
  • the coating is first applied to the material (seed only or seed plus other horticulture materials) using the least amount of moisture necessary to obtain a substantially uniformly coated horticulture system.
  • the material thus coated is then dried.
  • a free flowing (shakable, non-clumping) coated material is obtained.
  • the coated material may then be applied to the ground surface by a consumer via a shaker can (such as a container having openings in the mouth of the container of a size capable of controlled distribution of the material contained therein).
  • the container has a plethora of apertures, each aperture having a size sufficient to allow distribution of the composition and/or material from the container.
  • the horticulture system of the present invention contains a composition comprising coated seed and horticulture material.
  • the moisture content of the composition may be less than 20% by weight, or even less than 15% by weight, or even less than 10% by weight.
  • the moisture content of the composition may be in the range from 0.001% to 20% by weight, or even from 0.1 % to 15% by weight, or even from 1 % to 10% by weight.
  • the ratio of coated seed to horticulture material may be present in the range from 1 to 4 to 4 to 1.
  • the material After application of the coated material to the intended surface for germination, the material is typically watered (a re-wet step). Upon watering, the coating of the present invention adheres the components of coated material together with a thin layer of polymer. In other words, after re-wetting the coated horticulture material, it is no longer a free-flowing product. This action of re-wetting provides the applied horticulture material with an improved resistance to being washed away due to rain fall and/or other heavy watering, and even wind. The components are adhered together with enough tacky force that they resist undesirable movement from the germination location.
  • a device was designed to mimic a sloped surface.
  • the device allowed a test sample to be wetted, dried, and then re-wet.
  • the re-wet step included subjecting the test sample to a water spray while being held at an angle. An angle of 27 degrees was used for testing the samples.
  • Various sized nozzles and water pressures were evaluated so as to test the system over a variety of conditions. Three main test conditions were used:
  • a description of the seed coater can be found in MDS Methods, “SOP for Aginnovation Rotary 12 Seed Coater.”
  • the liquid polymer was then added to the seed coater. The material was allowed to dry for a few seconds. The coated material was then dropped to bag.
  • the prill sample contained starch and sodium polyacrylate.
  • the spray samples contained 50% active emulsified polyvinyl acetate.
  • the measurement shown in Table 1 represents seconds needed for approximately 50% of the preconditioned (wetting and curing) patty to wash away under the wash off wetting conditions.
  • Test results illustrate that horticulture material coated individually with the following components - sodium polyacrylate, polyvinyl alcohol, starch, and sucrose - improved the mulch patty’s “holding power” under extreme (tsunami) conditions but were actually worse under the milder (sprinkle) conditions.
  • polyvinyl acetate either homogenized or emulsified
  • the amount of durability given to the system appears to be a function of the amount of polyvinyl acetate applied.
  • the samples containing the seed coating of the present invention exhibit a glossy and/or shiny sheen which is apparent in the Figures.
  • the “dry application method” refers to a method of applying the seed coating to a material followed by resting overnight; therefore, no additional water is added after application of the coating.
  • the “pre-wet application method” refers to a method for applying the seed coating to a material, followed by resting overnight; and then, prior to use and/or further testing, additional water is added to the coated material to provide a wet surface.
