Seed Treatment – Colouring of Seeds

Most seed treatment contain dyes, and some companies add their own ‘ colour brand’ dye to seed treatments. Dyes serve two purposes.

1. As a warning that the seeds have been treated to prevent inadvertent contamination of food or feed, and
2. As a visible means of evaluating the completeness of treatment coverage.

The dyes, if used for treating formulation of dry seed, are mixed with fungicide and insecticide treatment.
