Dicamba is a toxic herbicide that drifts through the air and kills everything it touches—neighboring crops, trees, pollinators, even protected ecosystems. It’s been banned twice by the courts. Ask the EPA to keep it that way.

Tell the EPA to Ban the Chemical Killer That Destroys Everything in Its Path

The Environmental Protection Agency wants to reapprove dicamba—a weedkiller that federal courts have banned not once, but twice. The reason? Dicamba doesn’t stay where it’s sprayed. It vaporizes in the heat, drifts for miles, and leaves destruction in its path1.

Across the country, crops not engineered to tolerate dicamba have withered. Trees, wildflowers, and native plants have died. Pollinators like bees and butterflies suffer as their food sources vanish. Farmers have reported losing entire harvests because someone miles away used this chemical2.

This isn’t a farming tool—it’s a weapon with a mind of its own.

Communities and Ecosystems Are Paying the Price

Even with strict application instructions, dicamba has repeatedly escaped control. The EPA’s own guidelines have failed. New proposals attempt to mitigate the risk by restricting use in high temperatures, but experts warn that drift will continue regardless of these rules3.

Meanwhile, the damage reaches far beyond crops. Dicamba exposure can cause nausea, dizziness, vomiting, and eye irritation in humans. Pets and wildlife—especially birds and amphibians—show neurological symptoms after contact4. Runoff from treated fields can contaminate nearby soil and water, where it persists for weeks or even months depending on environmental conditions5.

Lobbyists Win, the Public Loses

The EPA insists dicamba poses “no significant human health risk.” Yet just weeks before the new approval was announced, the agency hired a former industry lobbyist to oversee pesticide regulation2. It’s no surprise that the agency is now ignoring science, court rulings, and public outcry to satisfy corporate interests.

Enough is enough.

Act Now to Protect People, Wildlife, and the Land

Farmers, scientists, and conservationists agree—dicamba must be permanently banned. It causes preventable harm, and its approval undermines trust in science-based environmental policy.

We cannot let a drift-prone herbicide continue to destroy what it cannot see.

Sign the petition calling on the EPA Administrator to stop the reapproval and enact a permanent ban on dicamba.

The Petition

To the Administrator of the Environmental Protection Agency (EPA),

We, the undersigned, urge you to reject any proposal to reapprove the use of the herbicide dicamba and instead take immediate action to impose a permanent ban on its use in American agriculture.

Dicamba has already been banned twice by federal courts due to its well-documented tendency to drift and cause widespread harm to neighboring crops, native plants, and sensitive ecosystems. Reapproving a chemical with such a destructive legacy would be a direct threat to public health, biodiversity, and the integrity of rural communities.

Evidence from scientific and government sources shows that dicamba exposure can lead to respiratory irritation, nausea, and muscle spasms in humans, with some studies suggesting possible links to cancer. Farm animals, pets, birds, and aquatic life have also shown clear signs of distress and illness following contact with dicamba-treated environments. In ecosystems, dicamba is a known contributor to pollinator decline and habitat destruction, weakening the very systems that sustain agriculture and natural life alike.

The Environmental Protection Agency must stand on the side of science, precaution, and the public interest. Reapproving dicamba against the warnings of experts and the rulings of the courts would place the agency's credibility and our nation’s ecological health at risk.

We ask that you affirm a full and permanent ban on dicamba, protect communities from chemical drift, and invest in safer, sustainable alternatives. By acting decisively now, you can ensure a healthier, more stable future for farmers, families, wildlife, and the environment we all share.

Sincerely,
