Unfortunately, there are not any selective post-emergent herbicides for use on dallisgrass in residential lawns. We recommend spot treating existing dallisgrass with a non-selective herbicide such as RoundUp QuikPro and then overseeding any bare spots as needed. If you only have a few clumps, then you can often easily pull or dig them out after rainfall.We recommend using a pre-emergent containing dithiopyr in late winter/early spring to help prevent new dallisgrass, such as Dimension 2EW or Crew Specialty Herbicide
