    Q
    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.

    Q
    Will Hi-Yield Grass Killer Post-Emergent Herbicide kill zoysia at the base of rose bushes without harming roses?
    A

    Hi-Yield Grass Killer Post-Emergent Herbicide is safe for use around roses as directed on the product label but it is not labeled to control zoysia.  Using a product such as GlyPhoSel Pro as a spot treatment will work to treat the areas where you have the zoysia invading, but it will also kill anything it comes into contact with so be sure to avoid any drift/spray contacting the roses themselves.

  • Asked by Steve from Independence, Mo
    08/07/2019
    Q
    Will Hi-Yield Grass Killer Post-Emergent Herbicide kill brome in tall fescue?
    A

    Hi-Yield Grass Killer Post-Emergent Herbicide is not labeled to control brome aka cheatgrass. Cheatgrass isn’t listed on many labels as its hard to control. You will likely need to use a product like Roundup to spot treat the cheatgrass and then fill in the bare spots with grass seed to try and keep it from coming back. There are a few pre emergents on the market that claim to prevent cheatgrass so you can look over those to see if you want to use them for prevention this fall and next spring. The Dimension 2EW is labeled to prevent brome/cheatgrass and can be used to prevent it and other weeds like crabgrass in the lawn.

  • 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.
