Control

Hand removal of individual plants, including the crown, can limit spread of small infestations
An insect biological control agent is available
Apply 2,4-D, chlorsulfuron, clopyralid, dicamba, glyphosate, or metsulfuron to actively growing plants prior to seed production; aminocyclopyrachlor, aminopyralid, or picloram pre- or post emergence
