Burdock Scouting and Prevention:

Mowing on a regular basis can help reduce the chance of this weed moving into your fields. Tillage early in the season before the seeds have a chance to grow and cultivate will reduce the chances of the weed being able to set roots and infest the fields.

Burdock Control:

This weed can be controlled by consistent mowing. By doing this, you will cut off the reproduction; by mowing before the weed has a chance to seed. Tilling is also very helpful to disturb the roots of the weed, making it easier to terminate.
