EPA Registered Agricultural Colorants
ORCO™Ag Dyes & Orcoperm™Ag Pigments are EPA registered and EPA approved agricultural colorants as an inert ingredient for use in crop protection and other environmentally sensitive agriculture applications including seed treatment and coating, fertilizers, crop protection, pond coloration, and agricultural marker dyes – with certain limitations as noted below.
EPA registered ORCO™Ag Dyes & Orcoperm™Ag Pigments are listed on the EPA Trade Name Inert Ingredient Listing database.
These agricultural colorants are available in highly concentrated powders and aqueous liquids (dyes only), designed for efficiency and flexibility of use in a variety of applications. With the EPA registered ORCO™Ag Dyes & Orcoperm™Ag Pigments product line, custom-color formulation services are available to meet your specific shade and physical property requirements.
Can these dyes be blended to make different shades?
Yes, these dyes can be blended, but then you will lose EPA Approval as the EPA Ingredient Listing Database is based on the actual trade name of the dye from Organic Dyes and Pigments LLC
Why are colorants added to seeds, fertilizers or pesticides?
Typically, colors are added so that when a pesticide/fertilizer is delivered through aerial spraying, you can see where those chemicals actually go, and make sue there is no over-spray on additional fields.
Is there any other reason color is added?
Frequently, manufacturers (or farmers) will add color in to differentiate types of pesticides or fertilizers, or to differentiate various types of seed coatings. Colorants are also added for overall branding for specific manufacturers.

Actual ORCO™ Ag Dye & ORCOPERM™ Ag Pigment samples must be evaluated in a laboratory on medium to be colored in production for accurate shade, physical properties, and application assurance. Shades shown on print material and computer monitors are for general reference only as they are inherently inaccurate due to calibration variations and technical limitations of monitors and printers.
