    Speed Zone Southern

    By Jim 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.

    Very effective stuff

    By Alex 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 what’s 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 it’s 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.

Questions & Answers

Have a question about this product?
  
Q
How 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."

Q
My dog ate grass with this on it and threw up - is she in danger of something bad?

How long do I have to wait before I can walk my dogs on grass treated with this?

A
The SpeedZone Southern Herbicide label states that once the product is dry, it is safe for pets to re-enter the treated area. Normally, an animal would have to consume a large amount to be affected by the herbicide. If you have any concerns, we recommend you contact your Vet and the manufacturer PBI Gordon at 800.821.7925 for clarification.
