Hello,
This is black medic. Black medic is often included on difficult-to-control weed lists. This is because medic can be resistant to many common broadleaf herbicide and herbicide combinations. Clopyralid, fluroxypyr, and quinclorac are among the most effective active ingredients for black medic. Two- and Three-way combination products can be very effective when applied in the fall.
