EPA Takes Next Step in Review Process for Herbicide Glyphosate, Reaffirms No Risk to Public Health

This announcement was originally published by the EPA on April 30, 2019. You can access more information here

Today, the U.S. Environmental Protection Agency (EPA) is taking an important step in the agency’s review of glyphosate. As part of this action, EPA continues to find that there are no risks to public health when glyphosate is used in accordance with its current label and that glyphosate is not a carcinogen. The agency’s scientific findings on human health risk are consistent with the conclusions of science reviews by many other countries and other federal agencies. While the agency did not identify public health risks in the 2017 human health risk assessment, the 2017 ecological assessment did identify ecological risks. To address these risks, EPA is proposing management measures to help farmers target pesticide sprays on the intended pest, protect pollinators, and reduce the problem of weeds becoming resistant to glyphosate.

“EPA has found no risks to public health from the current registered uses of glyphosate,” said EPA Administrator Andrew Wheeler. “Today’s proposed action includes new management measures that will help farmers use glyphosate in the most effective and efficient way possible, including pollinator protections. We look forward to input from farmers and other stakeholders to ensure that the draft management measures are workable, realistic, and effective.”

“If we are going to feed 10 billion people by 2050, we are going to need all the tools at our disposal, which includes the use the glyphosate,” U.S. Secretary of Agriculture Sonny Perdue said. “USDA applauds EPA’s proposed registration decision as it is science-based and consistent with the findings of other regulatory authorities that glyphosate does not pose a carcinogenic hazard to humans.”

Glyphosate is the most widely used herbicide in U.S. agriculture and has been studied for decades.  Glyphosate is used on more than 100 food crops, including glyphosate-resistant corn, soybean, cotton, canola and sugar beet. Non-agricultural uses include residential areas, aquatic areas, forests, rights of way, ornamentals and turf.

Once the Federal Register notice publishes, the public will be able to submit comments on EPA’s proposed decision at in docket # EPA-HQ-OPP-2009-0361. Public comments will be due 60 days after the date of publication in Federal Register. EPA’s responses to the comments received on the draft ecological and human health risk assessments and the benefits assessment will be in the docket.

EPA reaffirms finding that glyphosate does not cause cancer

The original article was written by Donnelle Eller and published on April 30, 2019 by Des Moines Register. You can access the full article here

The U.S. Environmental Protection Agency on Tuesday reaffirmed its finding that glyphosate, the world’s most popular herbicide, is not a cancer risk to users.

“There’s no evidence that glyphosate causes cancer,” said Alexandra Dunn, an EPA assistant administrator for chemical safety and pollution prevention. “There’s no risk to public health from the application of glyphosate.”

It’s the next step in the EPA’s process to re-register the herbicide, popular with farmers growing food and with families and businesses killing weeds.

The agency said its scientific findings on human health risk are consistent with the reviews by several other countries and federal agencies.

EPA Releases for Public Comment Draft Guidance for Plant Regulators, Including Plant Biostimulants

EPA is releasing for public comment Draft Guidance for Plant Regulators, Including Plant Biostimulants. Read a pre-publication copy of the draft guidance here.

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.

Once the Federal Register Notice publishes, the public will be able to submit comments on this guidance on in Docket # EPA-HQ-OPP-2018-0258. Public comments will be due 60 days after the date of publication in Federal Register.

EPA Applauds Presidential Signature of Key Pesticide Fees and Worker Protection Law

WASHINGTON — Today, U.S. Environmental Protection Agency (EPA) Office of Chemical Safety and Pollution Prevention (OCSPP) Assistant Administrator Alexandra Dapolito Dunn issued the following statement in response to President Donald Trump signing into law S. 483, the “Pesticide Registration Improvement Extension Act of 2018,” also known as PRIA 4:

“Since 2004, PRIA has been a key statute to ensuring timely review by EPA of pesticide registrations. PRIA 4 is supported by farmers and ranchers, environmental justice and worker protection organizations, and a broad array of manufacturers. EPA looks forward to implementing the new law to further the agency’s mission of protecting human health and the environment.”
