Alligare Panoramic 2SL Herbicide would not be recommended to use on lawns or in any areas where there are desirable grasses, plants, shrubs, etc due to the active ingredient (Ammonium salt of imazapic) leaves a long soil residual and prevents growth. 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 such as Dimension 2EW in late winter/early spring to help prevent new dallisgrass. View our Dallisgrass Prevention/Treatment Guide for more information.
