A New Film-Forming Agent Used to Improve Seed Coating Application Performance


Seeds used for growing crops often have one or more coatings. The coatings adhere agriculturally active components to the surface of the seed and impart a variety of beneficial properties. During manufacturing, transportation, and planting of the seed, the coating is exposed to a variety of conditions that may negatively affect the integrity of the coating or its adherence to the seed. To address these problems, film-forming agents are usually added in seed coating formulations as key additives. We recently developed a new polymeric solution comprising specific groups to interact with the seed surface. Experimental results indicate that the coated seeds using the new polymeric solution showed excellent anti-attrition performance, which is expected to enable integrity during production and transportation. The coatings also show good water resistance, which will enable the new film-forming agent to be widely used in various dry and paddy crop seeds, such as rice, corn, and soybeans. In addition, the film-forming agent maintains water/gas permeability and has negligible impact on seed germination.
