Safe, Effective Products

For 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 is the active ingredient in many Roundup® brand products and Ortho® GroundClear ® for weed control. It targets an enzyme found in plants but not in people or pets. 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.

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 glyphosate, the primary ingredient in Roundup® brand weed & grass killer products and in Ortho® Groundclear ® products, can be used safely to control damaging weeds. Over the past 40 years, independent scientific research throughout the world has continuously demonstrated this ingredient’s safety.

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.

For more information on how, and where, to responsibly use our Roundup® products, please see our usage tips.

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 can be used safely when label directions are followed.

IARC’s classification is inconsistent with the numerous multi-year, comprehensive assessments conducted by hundreds of scientists from countries worldwide who are responsible for ensuring public safety. In total, 160 nations have approved glyphosate for use.

It’s also important to note that IARC’s rating does not establish a direct link between glyphosate and an increase in cancer. In fact, in addition to glyphosate, IARC has also issued ratings that impact everyday items like coffee, cell phones, aloe vera extract, and pickled vegetables as well as professions such as hairdressers and barbers.

U.S. EPA: Concludes that glyphosate is not likely to be carcinogenic to humans.
The Agency’s assessment found no other meaningful risks to human health when the product is used according to the pesticide label. The Agency’s scientific findings are consistent with the conclusions of science reviews by a number of other countries as well as the 2017 National Institute of Health Agricultural Health Survey.News

In conclusion, we found no evidence of an association between glyphosate use and risk of any solid tumors or lymphoid malignancies, including NHL and its subtypes.News

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

“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
