When it comes to aquatic plant management, words matter

Millions of dollars are spent every year in Wisconsin to manage unwanted aquatic plants. Despite this, little funding or effort is dedicated to education specific to aquatic plant management. A Sea Grant study aimed at filling this information gap by identifying internet search terms.

Herbicide study finds good news, bad news for use of fluridone in lakes

In a study recently published in the journal “Aquatic Toxicology,” researchers found that while concentrations of the herbicide fluridone similar to those used when it’s applied to lakes to control Eurasian watermilfoil and hydrilla did not kill fathead minnows, it can impact fish health in more subtle ways.

Treating lakes for Eurasian watermilfoil with herbicides can harm young fish

Wisconsin Sea Grant’s Gavin Dehnert earned his Ph.D. by studying the effects of commercial 2,4-D herbicide exposure on the development and behavior of freshwater fish at different life stages. Now, he’s taking his research out of the lab and into the natural environment, where 2,4-D is used to treat lakes for the invasive plant, Eurasian watermilfoil.
