Mich. Admin. Code R. 285.715.6
Rule 6. Seed that consists of 2 or more varieties of the same kind shall be designated as a blend. The word "blend" shall be shown as a part of the name of the blend. Blends or mixtures may be assigned brand names but not variety names. The labeling and advertisements of varietal blends shall not create the impression that the seed is a single variety. For example, the soybean blend that consists of 2 varieties could not be named "golden pod soybeans" because "golden pod" could be mistaken for a variety name. The same soybean blend could be labeled and represented in an advertisement as "gold pod brand soybean blend." If the variety names of the components making up the blend are shown on the label, the percentage, by weight, of each named variety shall be shown in the order of predominance.
