Control

• Susceptible to dicamba, many biotypes tolerant to 2,4-D. Roundup controls this weed in no-till situations. Spray at rosette stage in fall or early spring Roundup controls this weed in no-till situations. Listed on Banvel label but not on Roundup or 2,4-D labels. Leaves are close to base of plant but cutting in mid summer cuts off seed umbels in the second year of growth. Annual cultivation destroys the first year plants and promotes germination to reduce the soil seed bank.

Other Comments

• One of most common weeds with complaints under the Weed Control Act, especially in urban areas.
