Safe, Effective Products

For nearly 150 years, we have earned consumer trust by providing products that help gardeners grow thriving gardens and landscapes. This includes offering products that control pests and diseases in order to protect environmentally favorable plantings and landscape investments. We are committed to using high-quality solutions that demonstrate safe use for families and the environment.

About Glyphosate

Glyphosate-based products have a 40-year history of safe use. In fact, there have been over 800 health and safety studies on glyphosate — many of which came from independent researchers. Glyphosate is the active ingredient in Roundup® brand products and select Ortho® brand products for weed control. It targets an enzyme found in plants but not in people or pets.

Our Approach to Product Stewardship

As consumers seek to control pests in and around their homes, we must work to ensure that our products can be used successfully, and responsibly, in a variety of settings. We understand that when it comes to safety, our consumers expect our products to be safe to use around people, pets, and the environment. This is why we continuously review what active ingredients we choose to use.

We involve many partners, including leading academic universities and research centers, when evaluating active ingredients for our products. We also work with regulatory agencies at the national and state/provincial levels to understand what active ingredients are best to use in different locations.

This is why we are confident in the labeled uses of glyphosate, the primary ingredient in our Roundup® brand products and select Ortho® brand products, for safe and effective use to control damaging weeds. Over the past 40 years, independent scientific research throughout the world has continuously demonstrated this ingredient’s safety. Environmental and health agencies, including the U.S. EPA, have also studied glyphosate and determined it’s labeled uses to be safe, as evidenced through multiple approvals for use during that same forty year time span.

Glyphosate targets an enzyme found in plants that does not exist in humans or animals. This is why it can effectively control weeds, but also why it has a safe history of use for humans and wildlife.

We take great pride in the science behind, and safety of, our products. We place high value on the world class scientific partners who develop the chemistry. We also highly value consumer trust in our products and work every day to uphold that trust. That includes providing products we know, and others have verified, are labeled for safe use.

A note on the International Agency for Research on Cancer (IARC)

In 2015, IARC issued a rating for glyphosate that gained a lot of media attention. However, this rating doesn’t appear to be based on any new data or to have included the full body of science from national environmental and health agencies that have all found glyphosate to be safe for labeled uses.

There have been numerous multi-year, comprehensive assessments conducted by hundreds of scientists from across the world which have affirmed glyphosate’s history of safe use time and again. In total, 160 nations have reviewed the scientific record and have concluded that glyphosate is safe for use.

The classification does not establish a direct link between glyphosate and an increase in cancer. In fact, the IARC classified glyphosate in the same category as everyday items like coffee, cell phones, aloe vera extract, and pickled vegetables as well as professions such as hairdressers and barbers.

“...RAC concluded that the available scientific evidence did not meet the criteria to classify glyphosate as a carcinogen”Quote

European Food Safety Authority
“...EFSA concluded that glyphosate is unlikely to pose a carcinogenic hazard to humans...”Quote

Canadian Pest Management Regulatory Agency
“Health and Welfare Canada has reviewed the glyphosate toxicology database, which is considered to be complete. The acute toxicity of glyphosate is very low. The submitted studies contain no evidence that glyphosate causes mutations, birth defects or cancer.”Quote

U.S. Environmental Protection Agency
“Several chronic toxicity/carcinogenicity studies…resulted in no effects based on the parameters examined, or resulted in findings that glyphosate was not carcinogenic in the study” and “Glyphosate does not cause mutations.” Quote

U.S. Environmental Protection Agency
“EPA has concluded that glyphosate does not pose a cancer risk to humans.”Quote

German Federal Institute for Risk Assessment
“In epidemiological studies in humans, there was no evidence of carcinogenicity and there were no effects on fertility, reproduction and development of neurotoxicity that might be attributed to glyphosate.”Quote

Australian Pesticides and Veterinary Medicines Authority
“The APVMA currently has no data before it suggesting that glyphosate products registered in Australia and used according to label instructions present any unacceptable risks to human health, the environment and trade. ... The weight and strength of evidence shows that glyphosate is not genotoxic, carcinogenic or neurotoxic.” Quote
