BASF, based in Ludwigshaven, Germany, has completed the purchase of Ames, Iowa-based Becker Underwood from Northwest Equity Partners for a price of $1.02 billion.
Becker Underwood was known for its seed treatment technology.
BASF will begin integrating Becker Underwood into the newly established global functional crop care unit, which is part of BASF's crop protection division, according to a news release.
As part of the move, BASF will merge existing research, development and marketing of seed treatment, biological crop protection, plant health, and water and resource management with those of Becker Underwood.
Becker Underwood's animal nutrition business will be folded into BASF's nutrition and health division.
The functional crop care unit will become effective Jan. 1, 2013.
