California Approves Marrone Bio Innovations’ Zequanox for Invasive Mussel Control

In California, Marrone Bio Innovations announced that the state of California has issued a Certificate of Pesticide Registration for Zequanox to control invasive zebra and quagga mussels (Dreissena species) in pipe systems and infrastructure.

Under this registration, Zequanox can now be used as an effective, environmentally responsible alternative to toxic, broad-spectrum chemicals (such as chlorine) to treat irrigation lines and water conveyance structures, as well as cooling and process water systems of industrial and power generation facilities. Zequanox is an EPA-approved, biological molluscicide for controlling zebra and quagga mussels. It is composed of dead cells from a ubiquitous soil microbe.
