The U.S. Environmental Protection Agency approved Marrone Bio Innovations' dry formulation of Zequanox, a biological product for controlling invasive mussels within enclosed systems and infrastructures, the company said.

“Zequanox is the first biopesticide available for controlling invasive zebra and quagga mussels, which are crippling industrial and commercial operations by restricting water flow in heat exchangers, condensers, fire suppression systems, and service and cooling water systems, as well as by damaging other infrastructure and equipment,” Marrone Bio Innovations said in a statement.

With Zequanox, 80 percent efficacy in controlling adult mussels and 90 percent in juveniles was demonstrated in multiple North American trials.

“Zequanox provides an effective and environmentally responsible method of controlling invasive mussels without incurring the risks commonly associated with harsh chemicals or the additional operating costs of mechanical solutions,” MBI director of water technologies Sarahann Rackl said in a statement. “We are pleased the EPA has approved this dry formulation, giving facility operators a new weapon in their fight to control invasive mussels.”
