    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!

    05/10/2016
    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.

  • Asked by Brent from New Orleans, La
    10/05/2017
    Q
    How often can I safely apply Hi-Yield Grass Killer Post-Emergent Herbicide to my Centipede lawn to control torpedo grass?
    I sprayed to control torpedo grass but have not seen any results after a few days. I wanted to know if I can spray again or if I should wait a certain number of days before reapplying. Also, the label lists using 2 tbsp per gallon on the chart but recommends 1 tbsp per gallon elsewhere. Is it safe to use the 2 tbsp amount on Centipede?
    A

    Hi-Yield Grass Killer Post-Emergent Herbicide is not specifically labeled for torpedograss. Solitare Herbicide is labeled to suppress torpedograss in centipede lawns, but may not eradicate it completely. Most of the herbicides on the market will only suppress the torpedograss for a short time. It is recommended to spot treat the torpedo grass with a non-selective herbicide such as Round Up Quick Pro and then reseed or sod in the treated areas.

    Q
    Can Hi-Yield Grass Killer Postemergence Herbicide be used on Empire Zoysia grass to control (kill) Bermuda?
    A
    Unfortunately Bermuda grass is so closely related to Zoysia grass that there is nothing that will remove Bermuda from Zoysia and not hurt the Bermuda as well.  In your situation it is recommended to spot treat the Bermuda with Round Up and kill it directly, and then replant Zoysia in those areas. We do carry some professional round up products:  http://www.domyownpestcontrol.com/nonselective-herbicides-c-188_408.html
