Zebra and quagga mussels may be small in stature, but there’s power in numbers and these tiny creatures are having a big ecological and economic impact throughout North America. The invasive mussel problem has been particularly pervasive and costly for the hydroelectric power industry, but recent scientific developments offer new hope for controlling these pesky invaders.
Zequanox, a new biological treatment, offers new hope for controlling invasive mussels at hydroelectric projects.

Marrone Bio Innovations, Inc. has received Certificates of Pesticide Registration from New York, Pennsylvania, Connecticut and Vermont for a biopesticide product [Zequanox] designed to control invasive quagga and zebra mussels at hydropower projects.
Marrone’s product — called “Zequanox” — is composed of dead cells from naturally occurring microbes which the company said provide a level of efficacy comparable to chlorine and other chemical treatments. This makes Zequanox biodegradable, non-corrosive and non-volatile, Marrone said, and removes the need for detoxification before water discharge. more
Biological product for controlling zebra and quagga mussels provides environmentally responsible alternative to chlorine and other toxic chemicals
Marrone Bio Innovations, Inc. (MBI) a leading global provider of biopesticides for water and agriculture applications, announced today that New York, Pennsylvania, Connecticut and Vermont have each issued a Certificate of Pesticide Registration for using Zequanox® to control zebra and quagga mussels (Dreissena species) in enclosed systems and infrastructures. Approved by the EPA in 2012, Zequanox now offers regional businesses such as energy producers, manufacturing companies and golf courses an effective alternative to toxic, broad-spectrum chemicals and costly microfiltration and UV light systems to control populations of invasive mussels.
BlueTech Research, an O2 Environmental company, recognizes Marrone Bio as one of the “most important innovative technology companies in the industry” and adds Zequanox to the BlueTech Innovation Tracker list.

More promising results have been announced for a naturally derived toxin that kills invasive zebra mussels but appears not to harm other aquatic life.
The toxin, Zequanox, was applied to isolated sections of an infested lake in the Chicago suburbs. The results: 97.1 percent mortality, and no observed deaths of fish, vegetation of other life in the area, according to results announced Wednesday, Dec. 12.

Study at Deep Quarry Lake showed more than 97 percent mortality of invasive mussels after applying Zequanox within barrier systems at three separate locations
Marrone Bio Innovations, Inc. (MBI) a leading provider of natural pest management products for water and agriculture applications, announced today that Zequanox® was highly effective at controlling invasive zebra mussels in Deep Quarry Lake located in DuPage County, Illinois. Zequanox, the industry’s only environmentally compatible molluscicide, was applied within barrier systems in three locations throughout the lake. Results showed that treated sites experienced an average mussel mortality of 97.1 percent compared with 11.2 percent mortality in the control (i.e., untreated) sites.
DAVIS, CALIF, September 13, 2012 – Marrone Bio Innovations, Inc. (MBI) announced today that it has been chosen for the 2012 Artemis Top 50 Water Tech Listing™, and earned the distinction as one of the five early market leaders generating revenues beyond $5 million. The selection of MBI to the list was based largely on its groundbreaking product Zequanox®, the industry’s first selective and environmentally compatible solution for the control of invasive zebra and quagga mussels that aggressively impact freshwater lakes and rivers.
“Zequanox offers significant benefits over traditional treatments such as chlorine and other biocides, and we’re proud to be recognized by Artemis for developing and commercializing this important product,” MBI CEO Pam Marrone said. “Unlike conventional mussel control methods—namely chlorine and other biocides—Zequanox is a highly effective biological that successfully maintains downstream water quality, while improving worker safety and supporting healthy aquatic ecosystems.”
