Recent increase in the production and sale of seeds has heightened
the scrutiny of organic seed quality and in particular brought attention
to concerns of seed-borne disease contamination. Seed-borne diseases
are pathogens such as bacteria, fungus, or virus that live on the
surface or interior of seed and have the potential to spread disease
further on. Conventional seeds are often treated or coated with chemical
fungicides to kill pathogens. It is always prudent to seek high-quality
seed and work with a reputable company.
Three methods of Seed Protection are
-
Encrustment
-
Pelleting
-
Film coating
Coated seeds can be distinguished visually from naked seeds, because of
their higher weight and different color, the shape of the seeds does
not change much though. The higher weight also provides for a better and
more secure ground contact and therefore provides a higher growth rate
than normal seed. Coated seeds are effective for the germination and the
juvenile development of young seedlings. The coat surrounding the seed
absorbs water which provides for a secure germination and with it a
secure start for the plant. The purely biological components of the coat
are non toxic to birds but also not attractive for them to eat, thereby
the seeds are saved from them. Coated seed is a huge step forward in
seed application and is suitable for most situations. The advantages of
this innovation are valid particularly for small inhomogeneous seeds and
also for seed mixture whether the seeds are sown by hand or machine.
Thus just not the look of the seed changes but its resistibility against
diseases, protection from bird and rodents, and lastly seedling is
protected. Over all the coating helps the seeds to grow as a healthy
sapling.
