The Biological Control of Spotted Knapweed in the Southeastern United States
<p>Spotted knapweed is an invasive, short-term-perennial plant that is native to Eurasia. It was accidentally introduced into North America in the early 1890's and has since spread across The United States and Canada. Spotted knapweed degrades rangelands and pastures by negatively impacting native …

Development and utilization of molecular tools to understand invasion biology in Centaurea maculosa (spotted knapweed)
… ecological phenomena in the invasive weed, spotted knapweed (Centaurea maculosa Lam.). In this dissertation, I first introduce the need for research at multiple scales and the potential benefits of collectively examining molecular, physiological and ecological phenomena in an invasive plant. …

Predicting Spotted Knapweed (Centaurea maculosa) Range Expansion Near Missoula Montana Using Localized Climate and Elevation Data
Since the 1920s spotted knapweed (Centaurea maculosa) has adapted to a variety of habitats, including pastureland, rangeland, hay land, open forests, road sides, and ditches. In 2003 this plant species dominated more than five million acres in Montana, half of the total infestation of noxious weeds …

Impact of Roadside Maintenance Practices on Larinus minutus (Gyllenhal), a Biological Control Agent of Spotted Knapweed
<p>Spotted knapweed, Centaurea stoebe, is an invasive weed found throughout much of the United States. Spotted knapweed is a rangeland weed where it was originally introduced into western North America in the 1880s.Where spotted knapweed spread to the southeastern U.S., it is found mostly along …

Effectiveness of Root-Boring Knapweed Weevil (Cyphocleonus achates Fåhr.) Herbivory on Spotted Knapweed (Centaurea stoebe Lam.) in Kamloops, BC: A Five-year Review
Spotted knapweed (Centaurea stoebe) is an Eurasian plant now invasive across North America. The root-boring knapweed weevil (Cyphocleonus achates) is one of 13 approved biocontrol agents. In 2017 and 2018, root-boring knapweed weevils were released at 15 sites across Kamloops, BC, Canada. This …

Catechin, a novel root exudate of Centaurea stoebe, exhibits pleiotropic effects on the soil microbial community and individual soil isolates, and undergoes chemical changes with numerous abiotic factors from soil
… been studied for (±)-catechin, a root exudate of spotted knapweed, as a plausible mechanism that facilitates knapweed invasion in North America. Phytotoxic effects are observed in invaded fields as well as greenhouse experiments when employing catechin or growing spotted knapweed, demonstrating …
