What is Prep-Coat?

In this process, the seed is primed and then pelleted. The result is a pelleted seed that prevents thermal dormancy. The resulting pelleted, primed seeds:

  • Are uniform in size
  • Are relatively dustless, which is easier on planting equipment
  • Split readily when exposed to moisture. These seeds break apart into two equal pieces, which allows air to reach the seed immediately. This is important because seeds respire, they require both moisture and oxygen.
  • Germinate faster
  • Increase seed lot uniformity allowing more uniform seedling emergence
  • Greatly reduce heat induced seed dormancy
  • Help to eliminate light sensitivity.
