No person shall distribute misbranded fertilizer. A commercial fertilizer is deemed to be misbranded:

(1)  If its labeling is false or misleading in any particular;

(2)  If it is distributed under the name of another fertilizer product;

(3)  If it is not labeled as required in § 2-7-5 and in accordance with regulations prescribed under this chapter; or

(4)  If it purports to be or is represented as a commercial fertilizer or is represented as containing a plant nutrient or commercial fertilizer, unless the plant nutrient or commercial fertilizer conforms to the definition of identity, if any, prescribed by regulation of the director; in the adopting of those regulations the director shall give due regard to commonly accepted definitions and official fertilizer terms as those issued by the association of American plant food control officials.
