On March 25, 2019, the U.S. Environmental Protection Agency (EPA) finally weighed-in on the murky and often misunderstood topic of label claims for plant regulators and plant biostimulants in posting its Draft Guidance for Plant Regulator Label Claims, Including Plant Biostimulants in Docket # EPA-HQ-OPP-2018-0258. EPA issued the notice of availability in the Federal Register on March 27, 2019. 84 Fed. Reg. 11538. EPA states that the draft guidance, issued under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), is intended to “provide guidance on identifying product label claims that are considered to be plant regulator claims” by EPA, thereby subjecting the products to regulation as pesticides under FIFRA. EPA notes that when determining whether a plant biostimulant may trigger pesticide registration requirements, or may be excluded or exempt from FIFRA regulation, a “key consideration is what claims are being made on product labels.” Comments on the draft guidance are due by May 28, 2019.
