Hybridization Facilitates The Rapid Evolution Of Reduced Herbicide Sensitivity In The Widely-Managed Invasive Aquatic Plant, Eurasian Watermilfoil, Elizabeth Ann Larue

Masters Theses

Eurasian watermilfoil (Myriophyllum spicatum) is one of North American’s most invasive and widely managed aquatic weeds. Eurasian watermilfoil also hybridizes with the native northern watermilfoil (Myriophyllum sibiricum) to produce many invasive and genetically diverse populations of hybrid watermilfoils. Both Eurasian and hybrid watermilfoils are commonly controlled with herbicides, but there has been recent concern that some hybrids exhibit reduced herbicide sensitivity. There is a lack of studies comparing the response of Eurasian and hybrid watermilfoils to commonly used herbicides. To determine if hybrids exhibit reduced herbicide sensitivity, I compared the sensitivity of hybrid and Eurasian watermilfoil …
