  • Asked by Scott from Smithville, Mo
    04/17/2018
    Q
    Is SpeedZone Lawn Weed Killer also a fertilizer?
    If not when can I apply fertilizer?
    A

    Speedzone is a post-emergent herbicide only: it does not contain any fertilizer. You can apply fertilizer as needed since it should not interfere with your herbicide application. Just be sure you do not mow within 2 days of an application of Speedzone.

    You can browse our lawn fertilizers here.

    Q
    Will Speedzone Lawn Weed Killer work to kill smartweed in PA?
    I have an area off 15000 sq f, almost half has been overtaken by the smartweed. What is the solution to bring back the lawn? Will lime & fertilizer stop this weed from coming back before & after being treated by your chemical?
    A

    SpeedZone Lawn Weed Killer Concentrate is labeled for and will treat for PA Smartweed. Please reveiw the product label to make sure your turf grass is tolerant of this product. ? You can help prevent the smartweed from coming back by using a pre-emergent such as Weed Impede to help prevent it from growing. We recommend that you consult with your local cooperative extension office Master Gardener on uses of lime and specific fertilizers needed on your turf based on the needs.

  • Asked by Ed from Buffalo, Ny
    04/16/2019
    Q
    Does SpeedZone kill lesser celandine?
    A

    SpeedZone Lawn Weed Killer Concentrate  is not labeled to treat Lesser Celadine. Herbicides which contain the active ingredient glyphosate, such as Round Up, are effective in controlling (but not necessarily eradicating) lesser celandine. Applications should be made in late winter or early spring when leaves are visible, but prior to full flowering, and when temperatures are above 40°F. Glyphosate will impact other vegetation so try to target only the celandine. It may take 1-2 weeks before the full effects of the treatment are visible.

    Q
    Will Speedzone kill rescuegrass in bermuda?
    A

    SpeedZone Lawn Weed Killer Concentrate is not labeled to treat rescuegrass.

    Unfortunately, there is nothing labeled to treat rescuegrass post emergently in your Bermudagrass.  For post emergent control, you would need to spot treat with a non-selective like Roundup QuikPro and reseed/sod.  You can use a pre-emergent labeled for rescuegrass to help prevent it from coming up the following season.  You would apply it in the spring and the fall and it will prevent the rescuegrass and other weeds from germinating and coming up.

  • Asked by Jay from Newton Nc

    Q
    Can you spray Speedzone on monkey grass to eliminate wild violets which are mixed in?
    A

    The product label for SpeedZone Lawn Weed Killer Concentrate does not list whether it will harm liriope, monkey grass, or mondo grass. These grasses are generally very hardy and only killed with non-selective herbicides such as glyphosate.  We would recommend testing a small area first to be sure.

    09/04/2019
    Q
    I know adding surfactant to SpeedZone will lower selectivity and damage the lawn but will it kill it?
    I know that adding a surfactant or MSO to speed zone will lower its selectivity and potentially damage turf. What kind of damage though? Will it be permanent and kill the turf or will it just temporarily damage it and stunt it? I think as long as it doesn't kill it the added surfactant might be beneficial if there are severe weed problems.
    A

    SpeedZone Lawn Weed Killer Concentrate already contains a small percentage of surfactant so you do not add another one.  It could cause permanant damage to the lawn or it may only be temporary, it really depends on the rate you use and if your lawn is under any type of stress such as drought or heat.

  • Asked by Christopher
    04/23/2021
    Q
    Can SpeedZone Lawn Weed Killer b tank mixed with Drive XLR8 to treat for clover and crabgrass?
    A

    Since SpeedZone Lawn Weed Killer Concentrate already contains a small percentage of surfactant and an additional surfactant is not advised on the product label and Drive XLR8 DOES require the use of a Methylated Seed Oil Surfactant for best results to treat crabgrass, we would not advise to tank mix these together for one application unless you test a small area of the lawn first. 

    If adding a surfactant to SpeedZone Lawn Weed Killer, you could possibly temorarily or permanently damage your lawn. We would recommend doing a small test spot application to the lawn to see if your turfgrass would be tolerant to using both in one application.

    Q
    I live in Mesa, Arizona, and have tiffgreen. Will Speedzone kill my lawn?
    4 weeks ago I spot treated with Spurge Power and Spots are still yellow and no signs of grass coming back.
    A
    SpeedZone Lawn Weed Killer Concentrate is tolerable on most common and hybrid bermudagrass such as Tifgrass. Temporary turfgrass yellowing may occur on certain varieties (F1 hybrids) of hybrid bermudagrass. To reduce risk of lawn injury, avoid spraying drought stressed lawns or when temperatures are above 85°F. Please read the product label for complete mixing and use instruction prior to using.

    Q
    Can I use Speed Zone herbicide on Mondo to control weeds without damaging the Mondo?
    I use Mondo as a ground cover
    A

    Speedzone could potentially harm Mondo grass. Depending on what type of turf grass you have, Fusilade would be a better option.

    05/03/2016
    Q
    Can Speedzone Lawn Weed Killer Concentrate be used on the garden area, and if so, how long before you can plant?
    A

    No, Speedzone Lawn Weed Killer Concentrate is not labeled for use in gardens. Since it is a broadleaf weed killer, it will harm the flowers that are there.

    We would recommend using an Over the Top product for use in a garden to kill grassy weeds.

    Q
    Can I use SpeedZone Lawn Weed Killer, safely, on Quackgrass in my flower gardens?
    A

    If you're trying to kill Quackgrass in your flower garden, then we wouldn't recommend using SpeedZone Lawn Weed Killer Contrate as it is not recommended to be used over flower beds. Grass Out Max is labeled to be applied in ornamental flower beds. Please refer to the product label for proper application.

    Q
    What is the best surfactant to use with "Speed Zone" herbicide?
    I used plain dish washing liquid as a surfactant for the "Roundup" I use on my gravel driveway. Could I simply use dish washing liquid with the Speed Zone as well? If not, what product that you sell would you suggest?
    A

     

    SpeedZone Lawn Weed Killer Concentrate does not contain a surfactant and the manufacturer does not state that one is required for use with it.

    Q
    Will Speedzone Lawn Weed Killer kill buttercups and other broadleaf weeds in Tall Fescue? Can I apply at the same time as grass seed and a weed and feed product?

    Q
    Will SpeedZone Lawn Weed Killer Concentrate kill centipede grass in my Bermuda lawn?
    I need something that will kill centipede grass that is invading my Bermuda lawn.
    A

    SpeedZone Lawn Weed Killer Concentrate is not safe for Centipede but is safe for established Bermuda. The best thing to do in your case would be to spot treat with a glyphosate based product such as Gly-Pho-Sel Pro and then replant the Bermuda in those areas.
