(1) The labeling is false or misleading;
(2) It is distributed under the name of another fertilizer product;
(3) It is not labeled as required in section 22-607, Idaho Code, and in accordance with rules prescribed under this chapter; or
(4) 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 rule of the department. In adopting such rules the department shall give due regard to commonly accepted definitions and official fertilizer terms as stated or provided for in section 22-603, Idaho Code.
