What is the difference between a biostimulant formulation and a pesticide formulation for EPA purposes?

Under FIFRA, a product that claims to prevent, destroy, repel, or mitigate a pest must be registered as a pesticide. Biostimulants that make only plant-nutrition or growth-enhancement claims may be exempt, but the distinction hinges on exact label language. A qualified crop input formulation chemist on AJ Cosmo Labs can review your intended claims and active ingredients to determine whether you need a full EPA Section 3 registration or can proceed label-exempt.
