Corteva

Corteva Agriscience is a global manufacturer of agricultural pesticides and seeds, deriving the majority of its revenue from this portfolio. The company produces and markets synthetic pesticides, including formulations containing chemicals linked to significant ecological and human health harms. A 2020 analysis found that more than a third of pesticide sales by major firms, including Corteva, contained chemicals highly toxic to human health, bees, or aquatic life.

The company’s herbicide Enlist Duo, a combination of 2,4-D and glyphosate, was the subject of a decade-long legal campaign by the Center for Food Safety over its risks. Both active ingredients have been linked to an elevated risk of non-Hodgkin lymphoma. In February 2026, Corteva canceled the nationwide registration for this product following litigation. Separately, in December 2022, a federal appeals court ruled the U.S. Environmental Protection Agency unlawfully approved the expanded use of another Corteva pesticide, sulfoxaflor, by failing to adequately consider its risks to bees. Corteva is also a defendant, alongside Syngenta, in a 2025 antitrust lawsuit filed by twelve state attorneys general. The complaint alleges the companies used “illegal” loyalty programs to block generic pesticides from the market, maintaining high prices for their products.
