Tools Needed

To use Speedzone EW Broadleaf Herbicide, you will need a hand-operated sprayer (backpack sprayer, handheld sprayer, pump sprayer) for small turfgrass applications or a professional spray ring for large-volume broadcast applications.

How to Use

• Step 1: First, determine which weed(s) you are targeting, the turfgrass type and the square footage of the area to be treated. This is important because if applied in a non-labeled area, SpeedZone EW Broadleaf Herbicide may damage or kill the turf. To calculate square footage, measure and multiply the area length times the width (length x width = square footage). To treat weeds on cool-seasoned turf, spray 1.1 to 1.8 oz. of SpeedZone EW Broadleaf Herbicide per gallon of water per 1,000 sq. ft. For warm-seasoned turf, apply 0.75 to 1.5 oz. of product per gallon of water per 1,000 sq. ft. For example, if you have warm-season turfgrass and measured 3,000 sq. ft., you will need to mix 2.25 to 5.2 fl. oz. of Speedzone EW in at least 3 gallons of water.
• Step 2: In a sprayer tank, fill the tank halfway with the required amount of water and then add the proper measured amount of Speedzone EW Broadleaf Herbicide according to your calculations. Mix and fill the rest of the way with the required amount of water and then agitate the sprayer until the product is well-mixed.
• Step 3: Make a uniform application to targeted weeds, making sure not to overspray or overlap and prevent any drift, When using a flat fan nozzle tip, spray the weeds at a suitable height to get even coverage. Moving your arms, such as in a swinging motion, will not give you a uniform spray. After the application, wait at least 1 to 2 days before mowing and do not water the grass for at least 3 hours.
