Marrone Bio Innovations, Inc. (MBI) a leading provider of natural pest management products for water and agriculture applications, announced 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.
In the study, funded in part through a grant from the Illinois Department of Natural Resources, three sets of paired treatment and control sites were set up within the lake to evaluate the effectiveness of Zequanox. Zequanox was so effective at controlling the invasive mussels that the study concluded after just one month. The study also showed that the application of Zequanox had no impact on water quality and no adult or juvenile fish mortality was observed 24 hours after product application.
“Zequanox has proven to be a powerful tool for controlling invasive mussels in ‘in-pipe’ applications such as cooling water systems. This study shows the product can be equally as effective in open waters,” said MBI Director of Water Technologies Sarahann M. Rackl, Ph.D., P.E. “This successful study represents MBI’s next step in our commercialization efforts for Zequanox in natural water bodies, and we’re excited about expanding into this new market, where there are currently no other environmentally compatible treatment options.”
