    5 of 5 stars  Speed Zone Southern
    By Jim in Virginia Beach, VA on 04/27/2012
    Verified Purchase

    My yard, approximately 3/4 acre, consists mainly of St. Augustine/fescue and was heavily infested with a variety of different weeds due mainly to lack of previous treatment (St. Augustine very sensitive to most herbicides). Mixed and applied SZS in accordance with directions at a rate 1.5 fl oz mixed in 2 gal. quantities per 1000sf. Positive results noticed within 2 days with approximately 98 percent positive results in 2 weeks (as advertised). Surprisingly, same species of weeds responded with a less positive results during same time periods. This may be due to uneven application caused by varying pump pressure as chemical was distributed. Distribution was performed using a hand pressurized fan sprayer with a 2 gal capacity. Little or no turf damage observed.

    5 of 5 stars  Very effective stuff
    By Alex in Cral Srings, FL on 01/14/2014

    I'm a first time homeowner in South Florida. Being such when I purchased my home I didn't have the slightest clue that there are things called weeds that slowly choke and take over your grass if left untouched. 4 years later my lawn was a mess. But in those four years I have grown to be an adept do it yourself homeowner. So after sodding about 25% of my lawn that was completely choked with weeds, I had to figure out how to get rid of the weed in the other areas. Most of which was anywhere from 40-65% weed mixed with grass. I also had some of the toughest weeds to kill. The toughest one was the creeping beggar weed. I didn't find anything from my research that treated it effectively without killing grass. And believe me I did a ton of research down to whatís the best method of getting rid of each individual type of weed in my lawn. After about 2 weeks of fruitless searching I found a website mentioning this herbicide as being extremely effective. So I bought and then applied it per the instruction and after just one application my yard is now only 10-20% weed! This stuff is AMAZING!! Killed 4 years of weed in just one application! Furthermore, my grass stayed completely green without any negative effect from the herbicide (St. Augustine) I was hesitant to buy it at first because of the price but itís completely worth it. Also there's enough herbicide here to last you anywhere from 3-5 years so in the long run its cheaper than most of the stuff you will buy at home depot. In fact comparing this to even the best thing home depot has to offer is like comparing an NFL team to a high school team. If you have the types of weed that this herbicide is designed for just stop searching for anything else and buy this. If you use it correctly it will destroy your weed without harming your grass.

    Got the Speedzone Southern Herbicide, sprayed it on as per the instructions and it quickly went to work. Took about 2 days for the burr weed to start dying. It is all gone now and two weeks later the Bermuda is coming in strong that the burr weed had been choking out before. Good stuff Thanks.

    By B in Valdosta, GA on 01/19/2016

    Proven winner for Southern turf. Kills broadleaf weeds faster than the rest. The added ingredient Carfentrazone is the key to the "Speed" Follow the instructions, use the proper equipment, and watch the weeds die.

    5 of 5 stars  No Bull.
    By S. in Hertford, NC on 08/09/2015

    I've struggled with beggar weed in our zoysia grass for several years. I tried the usual "weed selective" Ortho's Weed Be Gone sold through the warehouse stores to no avail. For that matter, it's totally disappointing at removing most any weed to include even a dandelion. I then studied Do My Own Pest Control's web site and learned of SpeedZone Southern Herbicide. Good stuff! Does what a selective weed killer is suppose to do. A little pricey but you get a large quantity that will last for quite some time.

    I sprayed my Bermuda hybrid with this product and it killed the broad leaf weeds as advertised. I did follow the instructions to the letter, even down to when to mow and not mow. I sprayed my yard 1/2 acre with my four wheeler making sure I stayed around 1.5-2 miles an hour as best I could. My grass didn't yellow much, even with the temperatures being on the border of being too hot per the instructions. One application of fertilizer the next week and it's back to its dark green color.

    This stuff isn't worth the shipping and the shipping is free. I used it once and nothing happened. Two weeks later I re-read the directions, mixed it a little stronger with the same results. I should of put 82.50 in a blender and dumped it on the lawn. Everything else I bought here has worked great. I had to give it one star because it won't let you give a zero.

QHow much SpeedZone Southern Herbicide do I mix with one gallon of water?

A

You will need to use .55 fl oz -1.5 fl oz per 1,000 sq ft. Please refer to the product label fro the correct usage rate for your needs.

Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.
Steps in Calibration:
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./1,000 sq. ft.) for Speedzone Southern from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of Speedzone Southern as determined in step 4.
Example: If the sprayer uses 2 gallons of water to cover 1,000 square feet and the desired application rate of Speedzone Southern is 1.5 fluid oz./1,000 square feet, then you would add 1.5 fluid ounces of Speedzone Southern to every 2 gallons of water to be used."

QAt what rate should i use speedzone southern in a 4 gallon backpack sprayer

A

The exact dilution rate of SpeedZone Southern Herbicide depends on the specific weeds you are treating. You will need to use .55 fl oz -1.5 fl oz per 1,000 sq ft. Please refer to the product label for the correct usage rate for your needs.
To determine how many gallons of water is needed to cover 1,000 sq ft depends on the sprayer. On average, it takes 1-2 gallons of water.
For example: If the sprayer uses 2 gallons of water to cover 1,000 square feet and the desired application rate of Speedzone Southern is 1.5 fluid oz./1,000 square feet, then you would add 1.5 fluid ounces of Speedzone Southern to every 2 gallons of water to be used.

QCan Speedzone Southern be applied if temperature rises above 85?
Can Speedzone Southern be applied to Centipede if temperature is below 85 upon application but rises later in the day above 85 degrees?

A

According to the Speedzone Southern product label you are prohibited from broadcast spraying when temperatures reach 85F degrees or above and spot treatments may cause injury as well when temps reach 85F degrees.  To avoid issues it would be better to apply later in the day when temps drop so that the treated area will not be exposed to high temps after application.

QI'm going to purchase SpeedZone Southern and would like to know which hose end spray if any you would recommend for the application of this product on a 5k sq ft lawn.

APre-emergent herbicides are not recommended to be used in a hose end sprayer because those sprayers are not accurate enough to apply the correct amount of SpeedZone Southern Herbicide. You will need to use a hand pump sprayer and uniformly spray the product over the specified area. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix  of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.

QI want to start a lawn program which includes insecticide/fungicide/fert and weed control on st Augustine fl
What products do I need? I have a company doing it now, buts it's expensive, trying to do it myself

AIn a St. Augustine lawn you can use Speedzone Southern Herbicide for your weed control. As a fungicide, Eagle 20EW is an excellent choice. To control insects, some popular lawn applications are Talstar P or Talstar XTRA Granules. We do also carry some fertilizers; however as they are newer to our inventory, that is not our area of expertise. You can always contact your local cooperative extension office and talk to the master gardener in your area for recommendations.

According to the Speedzone Southern product label: The turf tolerance to this product may vary and temporary turf grass yellowing may occur on St Augustine. Do not apply Speedzone Southern to Floratam, Bitterblue or other improved species of St Augustine.

I have either lespedoza or creeping beggarweed and lots of it. When should I use this product?

AMost all of the professional herbicides we sell come in a concentrate form and Speedzone Southern is no different.  You should apply about .55 to 2 ounces per 1000 square feet depending on what type of grass you have.  As far as when you should apply the product, it can be applied anytime that you see the weeds you would like to control.
