The guidance document provides guidance about plant regulator product label claims, including claims for products known as plant biostimulants. Plant biostimulants are a relatively new, but growing category of products containing naturally-occurring substances and microbes that are used to stimulate growth and reduce the effects of abiotic stress.  Plant biostimulants can promote greater water and nutrient use eficiency, but do not provide any nutritionally relevant fertilizer benefit to the plant. The guidance is intended to identify examples of products and label claims that are considered plant regulators as defined in FIFRA Section 2(v), and examples of products and label claims that are excluded from the FIFRA definition of a plant regulator as plant nutrients, plant inoculants, and soil amendments.
