Pennington applied for and was awarded a trademark for the color green when applied to grass seed, and the U.S. Supreme Court confirmed a color could be a company's trademark in the case of Owens-Corning and their "pink" insulation.

PENKOTED® seed has a unique advantage, containing a fungicide, a growth stimulant and a natural insect repellent. Birds tend not to eat PENKOTED® seed if they have an alternate source of food.

The famous PENKOTE® treatment was first used by professional landscapers and golf courses, long before the consumer began to recognize the advantages of PENKOTED® seed. Pennington continues to improve its PENKOTED® seed through continued research to seek better fungicides, better natural insecticides, better growth stimulants, and greater bird repellency.

A single lot of tall fescue seed was divided into equal parts. One part was PENKOTED®, the other was left uncoated The seed were then planted in the six planter boxes shown.

Pythium* Level One would be that level found in a consumer's lawn that we would rate as a moderate infestation.

Pythium Level Five would be a heavy infestation on a lawn.

Pythium Level Eight is a laboratory environment where the Pythium level would be several times greater than one would normally expect to find in a natural environment.

Notice the dramatic difference in growth and stand survivability between the PENKOTED® and uncoated seed.

*Pythium is a fungus found in soil. Pythium often attacks young grass seedlings and can severely damage an entire stand of new grass.

PENKOTED® and uncoated seed were grown in a petri dish in a laboratory environmnet Note the halo of protection around the PENKOTED® seed with the growth of fungus outside the halo. Laboratory proof of the effectiveness of PENKOTED® seed against fungus.

This picture indicates the stand survivability of tall fescue seed that has been PENKOTED® versus the same lot of tall fescue that was not coated. Note the increased survivability of the PENKOTED® seed over the uncoated seed.
