SpeedZone Lawn Weed Killer Concentrate 20 oz.

SpeedZone Lawn Weed Killer Concentrate contains the same percentages of active ingredient as the larger SpeedZone Red gallon size and 2.5 gallon size.

Speedzone is an excellent selective post-emergent herbicide with superior cool-weather performance and can be used on established cool and warm-season grasses for common and troublesome weeds in turf-grass such as spurge, pennywort, dandelion, and white clover. Evidence of injury can be seen within hours of application, and plants can die in 7 to 14 days. Safe to apply on Kentucky bluegrass, annual bluegrass, perennial ryegrass, tall fescue, red or fineleaf fescue, creeping and colonial bentgrass (excluding golf greens), and mixtures of cool-season species in noncropland (Kentucky bluegrass, tall fescue, smooth bromegrass, and orchardgrass). Uses include institutional, ornamental, and residential sites, sod production, and noncropland (rights-of-way, roadsides, medians, airports, and military installations). Spray solution must be above pH 5 and below pH 8.




HOW TO APPLY:

FOR ORTHO HOSE-END SPRAYERS FOR COOL-SEASON TURFGRASS

  • For Ortho Dial’N Spray Hose-End Sprayer or Gilmour Dial-A-Mix Lawn and Garden Sprayer:
  • SET THE DIAL: Set dial on 3 tsp. (1 Tbs.) per gallon.
  • FILL: Determine (Measure) the lawn area to be sprayed. Calculate square feet by multiplying length by width. The application rate for this product is 1.4 fl. oz. per 1,000 sq. ft. of lawn. Add an adequate amount of herbicide to the spray bottle to treat the total lawn area.
  • SPRAY: Spray evenly over the lawn.

Example: Measure 4.0 fl. oz. (8 Tbs.) into sprayer jar. Do not add water. Set dial on 3 teaspoons (tsp.) and spray uniformly on 3,000 sq. ft. of lawn. The maximum application rate to turf is 0.8 pound 2,4-D acid equivalent per acre per application per site. The maximum number of broadcast applications per treatment site is 2 per year.

SPOT TREATMENTS FOR COOL-SEASON TURFGRASS

  • For Hand-Operated Sprayers: For cool-season turfgrass, mix 1.0 fl. oz. of SPEED-ZONE Lawn Weed Killer per 1.0 gallon of water for treatment of approximately 1,000 sq. ft. of turfgrass. Apply any time the emerged broadleaf weeds are susceptible.

Caution: Do not apply SpeedZone Herbicide to bentgrass greens, carpetgrass, dichondra, legumes, and lawns with desirable clovers. Do not apply to new grass seedlings until after the second mowing. Delay applying SpeedZone for 3 to 4 wk on newly sodded, sprigged, or plugged areas. Do not irrigate turfgrass within 24 hr after application. Delay mowing 1 to 2 days before and after application. Treated areas may be reseeded 2 wk after application. Do not apply when air exceeds 90°F. Do not apply to any body of water, wetlands, irrigation ditch banks, or shorelines.

    By Travis in Lenoir NC on 05/06/2011

    Used and most of the weeds in my lawn were dead the next evening. It took just a couple days on the clover, but it's dead too!!!! Much better than round up and other brands I've used in the past that had little or not effect. I would highly recommend this to anyone wanting to get rid of weeds!!

    By Grey in Spokane, WA on 05/23/2012

    Great product for treating majority of broadleaf weeds and great amount of product if you don't need 1 gallon size. I blanket sprayed at 1.6 oz per 1000 sq. ft. I could see results next day. On the 4th day black medic, clover, speedwell, dandelion are all curled up and brown. Will see the end result and if there are any survivors in 2 weeks.

    We put an offer on this house late last summer and the homeowner let the grass grow out of hand, oh wait I meant the dandelions, LOL!!! We got the house in winter finally and spring time came & sure enough the dandelions returned in massive amounts, My kids loved it and did not. I bought speedzone and now 2 weeks later all the dandelions and weeds are no longer growing in my yard. I have purchased 3 products now from do my own pest control and all have worked tremendously. I hope this website keeps their prices down and free shipping because I will keep coming back.

    By Marshall in Oklahoma City, OK on 04/17/2012
    Verified Purchase

    About a month ago, my back yard had more henbit than it did bermuda grass. I sprayed the entire yard with Ortho without any noticeable difference. I purchased Speed Zone about 2 weeks later and sprayed again. I fully expected to spray the yard twice, but within a week, the yard was completely clear. Speed Zone completely exceeded my expectations.

    Verified Purchase

    It's been 2 weeks since I sprayed my lawn and the weeds are not dying as I expected. I thought that I would see the weeds wither more quickly. Maybe its a slow release formula. I thinking of doing other applications around the house, but not now.

QDoes Speedzone weed killer kill poa annua?
I have Kentucky bluegrass and I'm having problems controlling poa annua. Is this a good product to use or what Is a good product that you would recommend? Thanks!

ANo, Speedzone Concentrate is not labeled to kill poa annua. We would recommend using Blindside Herbicide. It is safe to use on your KBG lawn and is labeled to surpress poa annua. You will use 0.075-0.15 per 1000 square feet. You will likely have to do a subsequent treatment.

QHow soon can Speed Zone be re-applied?
I sprayed the yard about 10 days ago and I don't see any signs that the creeping Charlie is dying. I don't think I used enough product when I mixed it.

A

The SpeedZone Lawn Weed Killer Concentrate may be reapplied at 2-6 week intervals for more mature weeds, dense infestations, and for adverse environmental conditions. Make sure that you have measured the lawn area to be sprayed. Once you have the square footage of the treatment area you may then mix the labeled amount of SpeedZone (depends on your grass type) with water. Please note that the amount of water that is used is not important, what is most important is that you use the labeled amount of SpeedZone over the area you are treating.

How to Calibrate Sprayers

1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet, or 25 by 40 feet).

2. Place the sprayer on a level surface and add water noting the final level of water in the

spray tank.

3. Spray the marked area with a sufficient volume of water to provide uniform coverage.

Refill the sprayer to the same level as before measuring the amount of water added. The

measured water added to the sprayer is the volume needed to cover 1,000 square feet.

4. Determine the application rate (fl oz/1000 sq ft) - 1.1 oz per 1,000 sq ft up to 1.5 oz per 1,000 sq ft (depends on grass type)

5. To each volume of water used, as measured in step 3, add the amount of SpeedZone as

determined in step 4.

Example:

If the sprayer used 2 gallons of water to cover 1,000 square feet and the desired

application rate of SpeedZone is 1.4 oz/1,000 square feet, then you would add 1.4 ounces of SpeedZone to every 2 gallons of water to be used.

QCan SpeedZoneLawn Weed Killer be used on a new lawn (from seed) that is 7 weeks old and mowed 5 times already?

AThe SpeedZone Lawn Weed Killer label only states that you can reseed after 2 weeks of application.  Typically you want to mow the lawn at least twice before application so there should not be an issue on a lawn as established as what you described.
