Speed Zone Southern
By Jim on April 27, 2012My 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.

Don't bother
By Stan on June 6, 2011
Verified PurchaseThis 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.

Worked as Advertised
By Jason on July 5, 2011
Verified PurchaseI 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.

Not too happy
By Sharon on July 31, 2011
Verified PurchaseI'm STILL pulling weeds. I've applied this twice and it kills only a fraction of the weeds in my GA lawn. This was too expensive to not work.
It worked!

Verified PurchaseGot 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.

September 30, 2011Steve from Williamsburg , Va. asked:
QIs the gallon size Speedzone in concentrate form or ready to use? What is the coverage area?
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.
February 23, 2013Jesse asked:
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."
