Roundup’s Lesser-Known Cousin Is Coming to a Farm Near You

It’s the next wave in a revolution of GMO crops—and it’s happening right under our noses.

One of the world’s leading groups of cancer experts has just classified the industrial herbicide 2,4-D as a possible human carcinogen, and that’s got one of the world’s biggest ag-tech companies in an uproar. But why should we care about some corporate kerfuffle?

Because the U.S. is about to be deluged with 2,4-D—an herbicide similar to Roundup but lacking the comfort of a consumer-facing, trademarked name.

This week, the International Agency for Research on Cancer, an arm of the World Health Organization, released the results of its evaluation of three agricultural chemicals, including 2,4-D. The agency’s designation of the herbicide as “possibly carcinogenic to humans” is based on a review of the existing scientific evidence, which it deems “inadequate” in humans and “limited” in animal experiments—hence the emphasis on “possibly” carcinogenic. Nevertheless, the agency says, “There is strong evidence that 2,4-D induces oxidative stress, a mechanism that can operate in humans, and moderate evidence that 2,4-D causes immunosuppression, based on in vivo and in vitro studies.”
