One option is to remove the clumps with a shovel. Spot treatment with MSMA is legal on sod farms and golf courses. Repeat applications of Tribute Total (foramsulfuron + halosulfuron + thiencarbazone) in late summer and early fall will suppress dallisgrass in residential lawns. Make a follow-up application during the next growing season. Use Tribute Total only in bermudagrass. Another approach is spot treatment with glyphosate. Obviously, this is going to kill some of the desirable grass and leave brown spots in the turf. Two applications of glyphosate are needed. Apply the first after active growth begins in May, and spray again when regrowth appears. This will take most of the summer. Keep the glyphosate spray off non-target plants.
