The plant, which sits on 11 acres of land, formerly produced biodiesel and then glycerin, according to a news release.
In addition to the plant, the acquisition also includes offices and a laboratory.
In the months to come, crews will convert the facility to ferment the natural pesticides.
Once operational, the plant is expected to produce Grandevo, a broad-spectrum bioinsecticide, and Zequanox, a natural control for invasive zebra and quagga mussels.
Marrone has several other early-stage products in development that eventually could be produced at the plant, too.
Production is expected to begin in early 2013 and will initially employ 20 to 30 people.
