works great to control Spotted Knapweed. Milestone should be applied at 7 ozs per acre + Clean cut surfactant at 1 qt per 100 gallons per 100 gallons of water. We sell Milestone here at Arborchem in 1 qt containers and 2.5 gallon containers. Caution should
be used when spraying Milestone in root zones of black locust trees or where the spray could drift into canopy of locust trees.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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?<o:p></o:p></span></p>
