  • Asked by Ron from Buffalo My
    07/29/2022
    Q
    What are the mixing ratios
    A
    You can apply Prime Source Meso 4SC at 5-8 oz. per acre for pre-emergent control, which breaks down to 0.11 - 0.18 oz. or 2/3 tsp to 1 tsp per 1000 sq. ft. Be sure that you check the more detailed rates on the product label for your specific turfgrass since some grasses require the lower application rates. Usually you will use about 1 gallon of water per 1000 sq. ft. with a backpack sprayer but be sure you water-in your pre-emergent application after it is made.

    Q
    Will Prime Source Meso 4SC Select Herbicide kill bahiagrass?
    I have several lawns (fescue) that are infested with bahiagrass and I want to kill it. Bahiagrass is not listed on the safe to use on section. Therefore, I assume it will damage it or kill it? Or how about it's evil twin dallisgrass?
    A

    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
