Control: Prevention and Reporting

Once established, pale swallow-wort is difficult to control. Small patches must be dug out by hand. The entire crown must be removed and destroyed. Large stands can be managed to prevent seed crops by mowing when pods are very small (early July). Large stands can also be cultivated on a yearly basis to achieve control over time. Stay out of infested areas during seed dispersal to prevent seed dissemination to unaffected areas. Likewise, clean boots, ATVs and other equipment when coming out of infested areas.
