The latest alarming news surrounding GMOs is the impending USDA approval of Dow Chemical’s 2,4-D-resistant corn. 2,4-D is a highly toxic herbicide, and approval of this strain would mean increased 2,4-D use.

It’s a terrible case of irony. 2,4-D-resistant corn is being touted as a solution for farmers who are plagued by superweeds that have grown resistant to Monsanto’s Roundup herbicide. “We’ve got a whole epidemic of Roundup-resistant weeds due to the widespread planting of Roundup Ready crops and the increase in use of Roundup,” continues Freese. “These 2,4-D crops are being introduced as the supposed solution to Roundup-resistant weeds.

“In Vietnam, 2,4-D was combined with 2,4,5-T to make Agent Orange. Millions of gallons of Agent Orange were sprayed all over Vietnam, causing immense health harm to the Vietnamese and to US soldiers. This is a bad-news herbicide.”

Dow 2,4-D-resistant corn will be used in processed foods consumed by humans, as well as in cattle feed.

“You can see where this leads: first it’s Roundup resistance, then it’s 2,4-D resistance,” Freese says. “I call it a ‘chemical arms race with weeds’—you make crops with more resistances to more different types of herbicides, and then the weeds develop multiple resistances.”

This crop is up for approval with the USDA. “If the past is any guide, the USDA will approve the corn,” predicts Freese. “And we’ve already announced that we’ll challenge any approval in court.”

If 2,4-D is approved, others will follow, according to the New York Times. “The corn is just the first of a new wave of herbicide-tolerant crops. Dow is also developing soybeans and cotton immune to 2,4-D. Close behind, Monsanto is developing soybeans, cotton and corn that can tolerate dicamba, another old herbicide in the same family as 2,4-D. Bayer, Syngenta and DuPont are developing crops resistant to other herbicides too,” reports the New York Times.
