Apr 1, 2019Guidance for plant regulators, biostimulants comments sought
EPA is releasing for public comment Draft Guidance for Plant Regulators, Including Plant Biostimulants.(2 pp, 230 K, About PDF)
In recognition of the growing categories of products generally known as plant biostimulants, this draft document gives guidance on which products are (and are not) subject to regulation under FIFRA as plant regulator pesticides, and what kinds of claims can be made for them. The draft guidance provides examples of each. EPA is taking this step to provide clarity to our state regulatory partners, to industry, and to the interested public in this emerging product area.
Plant biostimulants are a relatively new, but growing, category of products containing naturally occurring substances and microbes that are used to stimulate plant growth, enhance resistance to plant pests, and reduce abiotic stress. Their increasing popularity arises from their ability to enhance agricultural productivity by stimulating natural processes in the plant and in soil, using substances and microbes already present in the environment.
Biostimulants can improve soil health, optimize nutrient use, and increase plant growth, vigor, yield and production. They can promote greater water and nutrient use efficiency but do not provide any nutritionally relevant fertilizer benefit to the plant. Plant biostimulant products can be used in sustainable agriculture production systems and integrated pest management (IPM) programs, which in turn can reduce the use of irrigation water, as well as agrochemical supplements and fertilizers.
