SpeedZone Southern EW Broadleaf Herbicide

SpeedZone Southern EW Broadleaf Herbicide, manufactured by PBI Gordon, is a selective post-emergent weed killer that controls 83 different weeds, such as clover or spurge, in warm-seasoned and cool-seasoned turf.

This emulsifiable concentrate product is rainfast within 3 hours and offers visible activity in hours. Complete control is achieved within 7 to 14 days. Its unique low-odor formulation and small droplet size result in better coverage with a minimum amount of product.

SpeedZone Southern EW Broadleaf Herbicide is ideal for sensitive southern grass species and is less odorless than the original SpeedZone Southern Broadleaf Herbicide. 

Tools Needed

This product can be applied with a tank sprayer, spray rig, boom sprayer, backpack sprayer, handheld pump sprayer, or hose-end sprayer.

How to Use

• Step 1: Determine which weeds 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 Southern EW Herbicide may damage or kill the turf. To calculate square footage, measure the treatment area's length and width in feet, then multiply them together (length X width = square footage). To treat weeds on Kentucky bluegrass, annual bluegrass, annual and perennial ryegrass, tall fescue, red or fine leaf fescues, or bentgrass, use 1.5 to 2.2 oz. of SpeedZone Southern EW Broadleaf Herbicide per gallon of water per 1,000 sq. ft. For bermudagrass, bahiagrass, buffalograss, centipedegrass, seashore paspalum, St. Augustinegrass, and zoysiagrass, use 0.7 to 1.5 oz. of product per gallon of water per 1,000 sq. ft.
• Step 2: Fill a sprayer tank halfway with the required amount of water and then add the proper amount of Speedzone Southern EW 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: Apply a uniform spray to targeted weeds, ensuring not to overspray or overlap and to prevent 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.
• Step 4: Stay off the treated areas until dry, and do not mow until 2 days have passed. Do not water the area for the first 3 hours.

Where to Use

SpeedZone Southern EW Broadleaf Herbicide can be used on southern warm-season and some cool-season turfgrasses found in residential lawns, apartment complexes, and condominiums. Ornamental turf sites around parks, streets, retail outlets, cemeteries, industrial and institutional buildings, recreation areas, playgrounds, fairgrounds, and athletic fields. Non-cropland sites, including farmyards, fencerows or fence lines, highway rights-of-ways (principal, interstate, county, private, and unpaved roads): roadsides, roadside ditches, road shoulders, road embankments, dividers, and medians; industrial sites: lumberyards, tank farms, fuel or equipment storage areas; municipal, state, and federal lands: airports and military installations, railroad rights-of-ways, railroad yards, railroad crossings and railroad bridge abutments; utility rights-of-ways: telephone, pipeline, electrical powerlines, and communication transmission lines. Agricultural sites like commercial sod production.

Do not apply to golf course greens.

Do not apply this product to 'Floratam' and 'Bitterblue' varieties of St. Augustinegrass, bentgrass mowed under 1/4 inch, carpetgrass, dichondra, legumes, and lawns where desirable clovers are present.

When to Use

Use when broadleaf weeds grow throughout the year. It is best to apply this when daytime air temperatures are above 50 degrees Fahrenheit, soil moisture is adequate, and weeds are young and actively growing.

If dry conditions exist, irrigation 24 hours before and 24 hours after the application will increase weed control.

Safety Information

Speedzone Southern EW Broadleaf Herbicide is safe to use when applied according to product label instructions. Always wear proper personal protective equipment (PPE) when mixing and applying this herbicide.

Do not apply this around any bodies of water, drainage areas, or agricultural irrigation systems.

Keep all people and pets off the treated areas until dry.

Special Considerations

SpeedZone Southern EW Broadleaf Herbicide can actually 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. 

Temperatures over 90 degrees Fahrenheit, moist soil, and high humidity will tend to increase herbicide activity. These conditions will also increase the possibility of temporary turf discoloration.
