As long as the seeding and application of Prime Source Meso 4SC Select were done within a week of each other, it should not prevent germination of your grass.
Prime Source Meso 4SC Select Herbicide will not control bahiagrass. Depending on your turfgrass type we do have some selective options for warm season turfgrass use.
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
