About 2, 4-D

2, 4-D is one of the most widely used weed control products in the world. The compound has been studied by hundreds of independent scientists and regulatory institutions and is considered one of the most thoroughly researched weed control products globally. Not one health and safety regulator in the world considers 2,4-D to be a human carcinogen. More than 4,000 published studies have been used in these evaluations and no herbicide has been more thoroughly studied.

We use 2, 4-D in a variety of our Scotts® Turf Builder® and Ortho® Weed B Gon® products in the US and Ortho® Killex in Canada. We stand behind its safe and effective labeled use, based on current and ongoing scientific study from health and safety authorities around the world – including US Environmental Protection Agency, Health Canada, the European Food Safety Authority and the World Health Organization – that continue to find that 2,4-D meets modern safety standards.

2, 4-D controls only broadleaf weeds. For more than half a century, 2, 4-D has been a major contributor in reducing agricultural costs, controlling harmful weeds in waterways and keeping damaging weeds out of home lawns, athletic fields and golf courses. Its major agricultural uses are on wheat and small grains, sorghum, corn, rice and sugar cane. It’s also used on right-of-ways, roadsides, non-crop areas and forestry.

What Others Are Saying

U.S. Environmental Protection Agency Pop Link
On October 14, 2014, the U.S. EPA published a memorandum in response to Public Comments received regarding an expanded use pattern in corn and soybeans. This response once again reiterated the EPA’s extensive studies which have found no cause-and-effect relationship between the use of 2,4-D and cancer. EPA concluded there is no additional epidemiological evidence that would implicate 2,4-D as a cause of cancer.

European Health Commission Pop Link
European Commission Health and Consumer Protection Directorate-General re-registered 2,4-D for all uses within the European Union.

Government of British Columbia Pop Link
2,4-D has little potential for carcinogenic effect is supported by the absence of effects in animal carcinogenicity assays, the absence of genetic effects of 2,4-D, the behaviour of the herbicide in the body and the biologically inconsistent and ambiguous results of epidemiology studies.”

European Food Safety Authority Pop Link
It concluded that “it was therefore agreed that 2,4-D, as currently manufactured, is unlikely to have a genotoxic potential or pose a carcinogenic risk to humans.”conducted with the technical active substance.”

PMRA Pop Link
“That 2,4-D meets Canada’s strict health and safety standards.” PMRA continues to hold the position that: “No other international regulatory body considers 2,4-D to be a human carcinogen. Based on all available and relevant data, Health Canada agrees with this position… Health Canada found that 2,4-D does not increase the risk of cancer and can be used safely by homeowners, provided label directions are followed”


  • Julie Goodman Video Harvard Professor Dr. Julie Goodman and her co-authors concluded that “The epidemiology evidence does not support an association between 2,4-D and NHL, gastric cancer, or prostate cancer risk.”
