On December 10, 2024, the U.S. Environmental Protection Agency (EPA) announced streamlined proposed registration review decisions for several biopesticides used in a variety of agricultural, commercial, and residential applications. These biopesticides present very low toxicity, exposure, and risks to human health and the environment, and there have been no human health or environmental incidents reported or new information that would necessitate additional assessment or reconsideration of EPA’s prior decision. The Agency is proposing that no further registration review is necessary for these biopesticides at this time. This streamlined approach allows EPA’s Office of Pesticide Programs to be more flexible and efficient with its limited resources.

Through the registration review program, EPA reevaluates each pesticide’s registration based on current scientific and other knowledge about the pesticide, including its effects on human health and the environment, taking into consideration any changes in law, regulations, or policy since the last review.

Pesticides go through a registration review process that can take years to complete. The provision in EPA’s regulations at 40 CFR 155.46 allow the Agency to determine that there is no need to reconsider a previous decision that a pesticide meets the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) standard for registration. This provision would not be appropriate for higher risk pesticides, pesticides about which adverse incidents have been reported, or those that have new scientific or information that would necessitate that the Agency conduct additional assessment and possibly change the Agency’s prior risk determination or required mitigations.
