(Medicago polymorpha)
Drawing by Andrew Schaible Burclover is a perennial which is very similar in appearance to
black medic. It contains a three oblong leaflets, the center leaflet
being on its own pediole. The leaflets often have brown spots on
the upper surface.
The flowers of burclover are yellow. Burclover reproduces by
seeds from “burred” seed pods as well as spreading prostrate
stolons which allows bur clover to tolerate close mowing.
Burclover is found from Virginia south to Florida, west to Texas and
Missouri.

Immature Stage
Integrated Pest Management Control Recommendations
Cultural Practices:
Preventive practices can discourage bur clover infestation. Mechanical or physical removal is not recommended,
as stolons may break and sprout with the potential to increase rather than decrease the infestation. If the turf is
kept under very close mowing conditions (6-8 mm), pluggers may be used effectively for physical removal. Good
turf management practices, including good liming and a nitrogen fertilization program, will encourage a dense
stand of turf and make it difficult for bur clover to become established.
Herbicide Use:
Knowing the optimum timing for a chemical control application will help to minimize the amount of chemical
required for bur clover control. For optimum control, make your herbicide application when bur clover is actively
growing and in the seedling to flower stage of growth.

Fall Panicum
(Panicum capillare)
Fall panicum is a grassy summer annual with a jagged app-
earance because it bends at its nodes. It has a very rounded stem,
prominent midveins in the leaves and a ring of hair as its ligule.
Fall panicum can reach a height of 7 feet. The seedhead, is a
large, open, branched panicle that takes on a purple tinge when
mature.

Herbicide Use:
Make preemergent applications during fall and spring to prevent germination.
