All,<br>
I am working on adding spotted knapweed to the list of invasive plants in the Mid-Atlantic that have biocontrol insects available for release, but the vast majority of published work deals with infestations in western rangelands. The implication seems to be that it rarely becomes invasive in the east, but maybe that is changing.<br>
Does anyone know of (1) infestations of knapweed in particular habitats in the east or (2) any states in the eastern US that have released biocontrol insects targeting this species?<br>
Thanks,<br>
Judy<br>

I'm glad we are giving this plant more attention. It is definitely an invasive in natural areas in the eastern states. See the EDDMapS based map of its distribution nationwide from the Invasive Plant Atlas of the United States.  I saw large infestations of it along I-70 and I-68 this past weekend in Allegany and Washington Cos. in Maryland.<br>

Attached is a pub on knapweed we did back in the 1980 - 90?s.<br>
We haven?t worked on it since then. Still a lot of knapweed here.<br>
