University of Minnesota researchers have reported limited success from an experiment to control an invasive weed in Lake Koronis near Paynesville.
Researchers from the Minnesota Aquatic Invasive Species Center have studying how to combat starry stonewort , which has been spread to 11 lakes across the state. They found that a combination of mechanical harvesting and algaecide greatly reduced the biomass of the plants in the treated area. And it was more effective than chemical treatment alone.
