d.The concentration of an active ingredient for a pesticide tank mix, as stated by the applicator and allowed by the pesticide label, shall not exceed or be less than the concentration of active ingredient stated by more or less than the tolerance for active ingredient concentration specified by this paragraph. Concentrations above or below the established tolerance shall be prima facie evidence of a use unsuitable, unsafe or inconsistent with its label or labeling. No pesticide shall be formulated into a tank mix at a concentration in excess of or below that permitted by the pesticide label without written approval from an authorized agent of the Oklahoma Department of Agriculture, Food, and Forestry:

(1)when the stated concentration or that allowed by the pesticide label is less than 0.51% the minimum amount of active ingredient in the tank mix shall be at least 60.0% and not more than 150.0% of the stated concentration or that allowed by the pesticide label when analyzed,
