Description:
Whole-lake techniques are increasingly being used to selectivelyremove exotic plants, including Eurasian watermilfoil(Myriophyllum spicatumL.). Fluridone (1-methyl-3-phenyl-5-[3-(trifluoromethyl)phenyl]-4(1H)-pyridinone), a systemicwhole-lake herbicide, is selective for Eurasian watermilfoilwithin a narrow low concentration range. Because fluridoneapplications have the potential for large effects on plant assemblagesand lake food webs, they should be evaluated atthe whole-lake scale. We examined effects of low-dose (5 to 8ppb) fluridone applications by comparing submersed plantassemblages, water quality and largemouth bass (Micropterussalmoides) growth rates and diets between three referencelakes and three treatment lakes one- and two-years post treatment.In the treatment lakes, fluridone reduced Eurasian watermilfoilcover without reducing native plant cover, althoughthe duration of Eurasian watermilfoil reduction varied amongtreatment lakes.
