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.

    I have tried just about everything to knock out Creeping Charlie in my lawn. Speedzone did it with ease. The results were noticed within days of the first application. It is an amazing product.

    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!!

    5 of 5 stars  Good product
    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.

  • 5 of 5 stars  Great job on clover in November
    By Bill in Woodbridge, VA on 11/28/2016

    I had spent a lot of time getting my yard back into shape during the fall and after finally getting the new seed to take and grow I noticed some clover starting to take hold. I used some weed killer from a big box store but it didn't have any effect. I decided to come here and do a little research since this is where I found the best product to kill my nutsedge. The SpeedZone worked like a charm even in the cooler weather. I didn't know that some weed killers only work well in hot weather. Great product!

  • 5 of 5 stars  Great Broadleaf killer
    By Liston in Mississippi on 07/25/2016
    Verified Purchase

    This is the best product (for the price) I have found for getting rid of broadleaf weeds in common bermuda. It takes care of spurge and buttonweed with no problem, but make sure you use a surfactant and a pre-emerge like generic barricade. The pre-emerge will prevent the seeds on the plant from germinating and returning (I've learned this after spot spraying all summer long). You can expect results in a day or two if used properly.

  • 4 of 5 stars  Speedzone Lawn Weed Killer Concentrate
    By Gary in Trout Lake, WA on 06/29/2016

    This product definitely nuked the vast numbers of dandelions that were growing large and vigorously in my lawn. Within a week every one I had spot treated (precisely per the instructions) was black and shriveling away. Yay! But the blades of grass near the dandelions became yellow, so now the grass is green with plenty of yellow areas. Not as bad as Roundup, but still yellow. In fairness to the Speedzone product, the grass itself was not thick and green and healthy, but thin blades of fescue that were dryish no matter how much they were watered. The soil is very dry as it drains instantly, being volcanic soil. I wrote this to alert others what result they may get if their grass is weak or dry. Speedzone is powerful.

    By Carl in wexford on 05/31/2016

    I bought this especially for wild violets which are invading parts of my lawn,particularly near where I borders a wooded area.. I have tried many others,ncluding BATTLESHIP with poor results Based on my first application of SPEED ZONE, I may have found a friend in my quesr..the wild violets are showing severe damage already...I will try another application in the fall and again next spring. It also seems to toxic to dandelion and some unnamed lawn vines and clover

    By Jerome in Wetumpka,Alabama on 04/26/2016

    This stuff REALLY works, I found its best when spraying the whole yard to use half of the recommend amount on your yard. It will turn some of the Bermuda grass a little yellow. After it rains a couple of time the grass will tun back to normal.

  • 4 of 5 stars  Better than most, but not all
    By Randolph in Virginia on 04/25/2016

    I got it for dandelions and it hands down takes care of what is visible in my lawn, but within a few days there are more dandelions sprouting up. Could just be that my neighbors are also infested with them, and don't seem to attempt to control them. I just applied a second spot spraying and it seems to do the job every time. Doesn't seem to work too well on clover. I did mix with a Horticultural Spray Oil as a sticker, but the clover hasn't died off yet after the second spraying. If the clover was as dead as the dandelions there would have been another star.

    3 of 5 stars  Worked a little too well
    By Bryan in Ohio on 04/09/2016
    Verified Purchase

    Applied this product to my lawn using a hose-end sprayer. Mixed and applied per the instructions. It took a few days, but I've seen a noticeable change in the few dandelions and clovers that had popped. All are shriveling and dying. One thing I did notice though is that the product killed off some of my grass as well. At first just the ends were turning brown, but now entire patches of grass have died. My yard is a fescue/blue grass mix that is supposed to be safe from this product. Probably would not buy again due to the damage to the grass. Three stars because it did a great job with the weeds, but also did a number on my grass.

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.

QDoes SpeedZone contain a surfactant?
I plan to use SpeedZone for spot treatment of Ground Ivy. Addition of a non-ionic surfactant is typically recommended for liquid herbicide application to broadleaf weeds. I do not see this recommendation on the label, nor do I recognize a surfactant on the ingredient list.

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. The SpeedZone Red which is very similar to the Lawn Weed Killer does state on the product label that adding one may reduce the selectivity on the turfgrass so it could harm your lawn in adding one.
