<p class="MsoNormal"><span style="color:rgb(31,73,125);font-family:"Calibri","sans-serif";font-size:11pt">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.

 targeting this species?<u></u><u></u></span></p>
