No person shall distribute misbranded fertilizer. A fertilizer shall be 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 KRS 250.376 and in accordance with regulations prescribed under KRS 250.421; or (4) If it purports to be or is represented as a fertilizer, or is represented as containing a plant nutrient or fertilizer, unless such plant nutrient or fertilizer conforms to the definition of identity, if any, prescribed by regulation of the director; in adopting such regulations the director shall give due regard to commonly accepted definitions and official fertilizer terms such as those issued by the Association of American Plant Food Control officials.
