Seed processing can include several steps. After harvesting, milling removes weed seed and other impurities, and cleaning improves the condition of the seed by eliminating disease, fungi or other pathogens that may interfere with the ability to germinate and grow.
Seed Treatments, primarily fungicides and insecticides, are used to protect the seed from seedling plant diseases and insects. As the traits of transgenic seed varieties and hybrids becomes more valuable, it is critical to protect that investment with seed treatments.
Proper storage of seed is vital to conserving its vigor and vitality. Seeds can last from a few years to centuries, depending on the species and the storage conditions. In general, most seeds stored in cool, dry conditions will survive longer than seeds stored in a wet, warm environment.
