SEED COATING COMPOSITION AND METHOD Abstract of the Disclosure A novel coating for crop seeds is dis- closed which serves to delay germination of the seeds after planting thereof for significant periods of time (such as over the winter months), and there- after allows germination and plant development in the normal manner. The preferred seed coatings include a relatively rigid, dried residue of a synthetic resin (e.g., an epoxide) which is filled with a material such as a hydrate former which slowly reacts with moisture from the earth and expands, so that the resin coating will rupture and allow seed germination when soil and climatic conditions are conducive to plant growth. It has also been discovered that a preferred precoating comprising methyl cellulose serves to enhance plant growth and hardiness, particularly in the period shortly after emergence.
