If farm raised seed is to be sold, a germination, purity, and noxious weed test must also be performed. Sample bags and forms are available at the Extension Office.

Circular bleached patches become obvious as snow begins to melt. There are two types that may be present being pink snow mold and gray snow mold. When wet, the bleached patches of grass caused by pink snow mold fungus show light pink fluffy growth.
