(2) adequate warning statements or directions for use which may be necessary to protect plant life, animals, humans, aquatic life, soil or water are not shown upon the label;

(3) its composition falls below or differs from that which it is purported to possess by its labeling; or

(4) it contains viable weed seed in amounts exceeding the limits which the department establishes by regulation.

(b) Exception.--A soil amendment or plant amendment shall not be considered adulterated under this section if the quantity of the substance in the soil amendment or plant amendment does not ordinarily render it injurious.
