Corteva, Inc. (also known as Corteva Agriscience) is a major American agricultural chemical and seed company that was the agricultural unit of DowDuPont prior to being spun off as an independent public company.
It is the biggest pure play (stand alone) agricultural organization in the world. DowDuPont announced the Corteva name in February 2018, saying that it was "derived from a combination of words meaning 'heart' and 'nature.'" Corteva became a public company on June 3, 2019, when DowDuPont distributed Corteva shares to its shareholders.
The DowDuPont agricultural businesses that became Corteva had revenue of over $14 billion in 2017, which would have placed the company in the Fortune 500 for that year.
