varieties are Blue Tag Certified by the Tennessee Crop Improvement
Association. TCIA inspects the grass at each producer's farm three
times a year to ensure genetic identity. If it fails due to excessive
off-types, they are not allowed to sale as certified until the off-types
are eliminated. This is done so that if you buy Tifway 419 at one
certified location, you have proof that is the same quality and
variety grass as another certified producer location. Be sure to
ask for the Blue Tag Certificate when you purchase certified grass.
