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.
