SpeedZone EW Broadleaf Herbicide

SpeedZone EW Broadleaf Herbicide, manufactured by PBI Gordon, is a selective post-emergent weed killer that significantly controls many broadleaf weeds found on warm and cool-season grasses.

This emulsifiable concentrate product contains four main active ingredients. Carfentrazone, which demonstrates fast, effective weed control of some of the most challenging weed species, such as spurge, dollar weed, dandelion, and white clover.

SpeedZone EW Broadleaf Herbicide delivers a visual response within 24 hours; weeds usually die within 7 to 14 days.

Tools Needed

For small turfgrass applications, you will need a hand-operated sprayer (backpack sprayer, handheld sprayer, pump sprayer) 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 the treatment areas' length and width in feet, then multiply them together (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: Fill a sprayer tank with the required amount of water and add the adequately measured amount of Speedzone EW Broadleaf Herbicide according to your calculations. Mix and fill the rest of the tank with the required amount of water, agitating the sprayer until the product is well-mixed.
• Step 3: Make a uniform application to targeted weeds, ensuring 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 swinging, 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. If necessary, a second application may be made 30 days after the initial application. Do not make more than 2 broadcast treatments of this product per site per year. 

Where to Use

Labeled for use on cool season turf such as Kentucky bluegrass, annual bluegrass, annual ryegrass, perennial ryegrass, tall fescue, red fescue, fine leaf fescue, creeping bentgrass, colonial bentgrass (excluding golf greens), smooth bromegrass, and orchardgrass. 

Warm seasoned turf to be treated are Common Bermudagrass, hybrid bermudagrass, zoysiagrass, and buffalograss.

When to Use

Apply when weeds are young and actively growing since this is when they are weaker and more susceptible to herbicide treatments. Apply on calm (non-windy) days when rain is not in the immediate forecast. 

Applications during winter-to-spring and fall-to-winter transition periods are not advised. 

Safety Information

Special Considerations

SpeedZone EW Broadleaf Herbicide can be mixed with liquid fertilizers or adjuvants like surfactants or drift-reducing agents to give you a broader spectrum of control. But always remember to read labels for use restrictions and test your mixed solution on a small, discreet patch of grass to monitor any adverse effects.
