    Q
    Can I use Hi-Yield Grass Killer Post-Emergent Herbicide in freshly tilled soil?
    We grow on 2 acres and have Johnson grass problem.
    A

    Hi-Yield Grass Killer Post-Emergent Herbicide will last in the area that was tilled. If you are trying to replant in that area, it would be best to apply a non-selective (kills all grass-no selective-will eradicate desired turf also) such as Killzall or RoundUp QuikPro and wait 7-14 days prior to planting in that area. If you are seeking a selective application, please let us know. Thank you!

    Q
    Will Hi-Yield Grass Killer Post-Emergent Herbicide get rid of bermuda grass in a centipede lawn?
    A

    No, Hi-Yield Grass Killer Post-Emergent Herbicide will not get rid of bermuda grass in a centipede lawn.  Unfortunately, centipede and bermuda grasses are so closely related that any product that would kill the bermuda would also kill the centipede.  In this type of situation, we usually recommend using a glyphosate product such as Roundup Quik Pro to spot treat the bermuda grass as much as possible, and then replanting the centipede in a couple of weeks when the bermuda is gone.
