There has been some excellent discussion of hawkweed, wrapping up with
information that the reason that hawkweed is such a problem in some
areas is that it is allelopathic.   While some organic controls were
suggested, I would really like to fish for:  in what way is hawkweed
allelopathic?  What does it do to kill surrounding plants?

Anybody know?

Anybody know somebody that might know?
