Removal of spotted knapweed
Hi there, my name is Caity and I'm doing a presentation on spotted knapweed (Centaurea stoelbe). I need a professional reference, so I figured I'd give this a shot. I was wondering what you believe the most effective method of removal for the spotted knapweed would be? Could I get your name and title to put down in my references also? Thanks!

Thank you for your question, Caity. We have spotted knapweed in Oregon, but different species than the one you’re interested in. (https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/ec1559.pdf) Here are articles from other states addressing your plant’s control: https://wric.ucdavis.edu/information/natural%20areas/wr_C/Centaurea_stoebe.pdf and a longer one here: http://culter.colorado.edu/~tims/Knochel_Seastedt_2009.pdf Since I am only the messenger, and not the author of the articles, you should cite the authors as your sources/references. Good luck!
