    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

  • 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.

  • Asked by Greg from Waycross,ga.
    07/11/2014
    Q
    Will Hi-Yield Postemergence herbicide stop Bahiagrass from seeding in a yard with Centipede and St. Augustine?
    A
    Hi-Yield Grass Killer Post-Emergence Herbicide is intended to kill grassy plants and is not labeled for use in desirable turf. This is also a post-emergent, rather than a pre-emergent, so it will not prevent new seed germination. The three grasses you have listed are all warm-season grasses, so any product that would affect seeding of one would affect all of them. You could use a non-selective herbicide such as RoundUp QuickPro to spot treat areas where you want to eliminate the bahiagrass and then reseed after two weeks.

    Does Hi-Yield Grass Killer Post-Emergent Herbicide will kill clover?
    A

    Hi-Yield Grass Killer Post-Emergent Herbicide does not list clover as one of the types of weeds controlled on the label. We would recommend using QuinKill Max Crabgrass & Weed Killer depending on what type of turf you have.

    Spot Applications: Apply 1.45 fl ozs of QUIN KILL MAX per 1000 sq ft (0.75 lb ae/A) of treated area. Make 2 sequential applications of 1.0 fl oz (0.51 lb ae/A) of QUIN KILL MAX per 1000 sq ft and an additional sequential application up to 0.90 fl oz (0.46 lb ae/A) of QUIN KILL MAX per 1000 sq ft at 14- to 21-day intervals.
