SpeedZone Herbicide

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 turfgrass 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.

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.

    4 of 5 stars  Impressed so far
    By Matt in Charlotte, NC on 06/03/2011
    Verified Purchase

    I waited a little too long (May 20) to try to kill the wild violet in my yard with Speed Zone. One treatment killed about half of it and very fast. Temps are above 90 now so I guess I'll try again in the fall or spring so I don't injure the grass. Be very careful if you have a vegetable garden though. I sprayed in what I thought was calm conditions and it managed to drift enough to cause injury in my garden. Next time I'm putting a tarp barrier up.

    5 of 5 stars  Post Emergent herbicide
    By John in Sudbury, MA on 06/08/2012
    Verified Purchase

    Late April 2012 I planted a new lawn by seed--approximately 3/4 acre, consisting of a mixuture of cool and warm season grasses. The imported top soil was unfortunatly loaded with weed seed which came up along with the new grass. The weeds were dominated by Virginia Knotweed, which at 6 weeks were ~12" inches in height and beginning to form seed heads. Using a 1:1 mix (oz Speed Zone to gallon water), due to the new grass being ~6 weeks mature, Speed Zone killed the knotweed and did not harm the tall fescue/little bluestem mix. Weeds wilted within 24 hrs and were mowed 7 days after application--the first cutting for the new grass. There are a few nut grass still in the seeded area not killed by Speed Zone, but these are small enough instances to be pulled. Speed Zone was very effective at controlling post emergent weeds in a stand of newly planted grass seed. I plan to extend it's use to my established lawn--spot treating small areas of white clover and oxalis (woodsorrel).

    3 of 5 stars  SpeedZone is a good choice
    By Sa in Denver, CO on 06/29/2011

    I've been using SpeedZone commercially for 4 years now, on about 190K sq. feet of 'high impact' grass areas. It's the best product for Dandelions, which has been a hard one to beat. I like to use it in conjunction with a liquid fertilizer. This helps SZ to work faster for me. Dandelions propagate so quickly, the product needs to work as fast as possible. SZ is not the best choice for thistle, but any other cheaper herbicide with 2,4-D will handle that.  SZ keeps your tank and pump clean, which many others do not. Lastly, I've cut back my use of SZ this year because of its cost. I've tried diluting a little, but then it doesn't work. I would use it more, if it cost less.

    Not withstanding use restrictions, this stuff does the job! It took care of problems that Ortho wouldn't and more! You still have to pull the dead material so the lawn isn't full of dead weeds though.  I recommend this for serious, no kidding around post-emergent turf weed control!

    By Jackie in Huntsville, AL on 03/26/2012

    SZ works great on Chickweed, Henbit and Dandalions. It did not get my clover and it does not work on crab grass. It does work well in the cool Springtime and even if it rains the next day. The note said rainproof in 4 hours.

    By D in Illinois on 04/30/2016

    Using a Chapin battery-powerd backpack sprayer, I spot sprayed 2 1/2 acres with SpeedZone mixed with High-Yield Spreader Sticker and my dandelions and thistles are deader than a doornail. Spray two or more days after you mow and a couple days before you mow again (with temps in the 50's to a high of 80) and every single weed you spray will die and not come back. Bye bye $548 a year professional weed man.

QApplication rates for Ortho Dial-N-Spray
I would like to use non-Ortho concentrates in my Dial-N-Spray sprayer but I cannot find conversion ratios. For cool-season turfgrasses I prefer Bonide Weed Beater Ultra, but its broadcast application rates are listed in pints per acre. I am treating 9000 square feet and have no idea what setting on my hose-end sprayer to use. For spring treatments next year I would also like to use Speedzone Red, which lists rates for ounces per thousand square feet and gallons per thousand square feet; not ounces per gallon.

AGenerally, one gallon of mixed solution will treat 1,000 sq feet. So, Speedzone Red would be approx 1.5 fl oz per one gallon of mixed solution to treat 1000 sq. feet. Please follow the product labels for application. The same can be said for Bonide Weed Beater Ultra. the product label suggests mix 1.5 - 2.4 fl. oz into one gallon of water to treat 1000 square feet.

QCan SpeedZone Red be used on Floratam or Centipede grass?


While SpeedZone Red is labeled to control creeping beggarweed, it is not labeled for use on Floratam St. Augustine but is for Centipede.

Celsius WG is labeled for creeping beggarweed in Floratam and Centipedes grasses and when used as directed on the product label will do a great job helping you eliminate this pest weed

QCan I use speed zone around trees and bushes?
I have a major weed problem around my trees, bushes and lawn. I want to kill the weeds but do not want to damage the other vegetation. I also want to plant more vegetation once I have the weeds gone. Should I use roundup or speed zone weed killer?

AIf you want to plant other vegetation once the weeds are gone you have to use a round up type product since glyphosate, the active ingredient in round up, does not stay for long in the soil.  If you apply speed zone or other selective herbicides, you will not be able to plant any other vegetation for some time.  The quickest way is to spot treat weeds with a glyphosate product.  We carry a full line of professional weed killers that are actually much cheaper per finished gallon than over the counter round up.

QHow many ounces of SpeedZone Red do I need for a gallon of water?

AWe cannot answer your question without more information.  Mixing instructions depend on what type of grass you have, how large of an area, and what type of weeds you are treating.  All of the mixing instructions are on the product label.  Just look on the label for the type of grass that you have and then it will tell you how much to mix per 1000 square feet based on the weeds you are treating.

QBest herbicide to kill Pennsylvania Smartweed in turf during mid to late spring in Pennsylvania?
Have a very stubborn and dense infestation of Pennsylvania Smartweed. Have used Speedzone last couple of years only to have it come back again. What am I doing wrong? Should I try another product, maybe Surge? Do I need to add anything to a herbicide?

ASpeedZone will only kill the weeds that you spray directly it does not prevent anything from coming back.  You can help prevent the smartweed from coming back by using a pre-emergent such as Weed Impede to help prevent it from growing.
