The goal of the seed program is to enforce the Colorado Seed Act which requires that the seed label, the germination, and purity content of the seed is accurate.
The program also inspects the seed to ensure that prohibited noxious weeds are eliminated and restricted noxious weeds are below a certain level per pound of seed.
“The general assembly hereby finds and declares that truth in labeling of seed is of paramount importance to the citizens of Colorado."
