§ 163.11 - Registration under the Federal Insecticide, Fungicide, and Rodenticide Act.

(a) Since in most cases where a pesticide chemical may leave a residue in or on a raw agricultural commodity there can be no determination of the adequacy of the directions for use or the warning or caution statements appearing on the labeling of an economic poison until a tolerance or exemption has been established for the pesticide chemical which is, or is a part of, such economic poison, it will not ordinarily be possible to register the economic poison under the Federal Insecticide, Fungicide, and Rodenticide Act until such tolerance or exemption has been established.

(b) Factors other than pesticidal, or biological, effectiveness are considered in the granting of registration under the Federal Insecticide, Fungicide, and Rodenticide Act. Therefore, the criteria for registration are not all applied in considering the certification of usefulness, and the fact that such a certification has been made does not mean that the economic poison can be registered for the uses concerned.
