    Q
    Will Prime Source Meso 4SC Select (Generic Tenacity Herbicide) still work if I purchased it in the fall and it is now separated?
    I used some in the fall and kept it in the garage over the winter. Temp in the garage never got below 10
    A

    It is best to store chemicals such as Prime Source Meso 4SC Select in a cool dry place away from extreme temperatures (below freezing and above 85) and direct sunlight.  If the product was exposed to below freezing temperatures and it is separating and will not mix back up, then it would be recommended to replace as it may not be as effective.

    Prime Source Meso 4SC Select is not labeled to control hairy bittercress. Quincept Herbicide is a great choice for hairy bittercress control as well as a wide variety of other weeds. Be sure to check the Product Label for your grass type to make sure its one of the tolerant species for using this product over it safely.

    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
