The SpeedZone Lawn Weed Killer Concentrate may be reapplied at 2-6 week intervals for more mature weeds, dense infestations, and for adverse environmental conditions. Make sure that you have measured the lawn area to be sprayed. Once you have the square footage of the treatment area you may then mix the labeled amount of SpeedZone (depends on your grass type) with water. Please note that the amount of water that is used is not important, what is most important is that you use the labeled amount of SpeedZone over the area you are treating.
How to Calibrate Sprayers
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/1000 sq ft) - 1.1 oz per 1,000 sq ft up to 1.5 oz per 1,000 sq ft (depends on grass type)
5. To each volume of water used, as measured in step 3, add the amount of SpeedZone as
determined in step 4.
Example:
If the sprayer used 2 gallons of water to cover 1,000 square feet and the desired
application rate of SpeedZone is 1.4 oz/1,000 square feet, then you would add 1.4 ounces of SpeedZone to every 2 gallons of water to be used.
