I found one site on Yellow Star thistle that might help.
http://www.snowcrest.net/tcrcd/yst.htm
The information given there, especially the prevention information, is
similar to that for other knapweeds (Centaurea) spp such as Russian knapweed
and spotted knapweed which have become a serious problem east of the
Cascades in Washington, on into Montana. In Leavenworth, WA, people
concerned about spraying, which kills other species as well, have organized
an effort where people "adopt a stretch" of highway and monitor it, pulling
knapweed before it can go to seed. Recently there has been some concern
about cancer-causing agents in knapweed, so gloves are recommended (and for
star thistle, requisite I suppose!).
