Expel Turf Herbicide, manufactured by CSI, is an easy-to-use soil-applied product that controls difficult weed species such as yellow nutsedge or spurge in warm-seasoned and cool-seasoned turfs within residential, commercial, or institutional lawns.

Once applied, this liquid-formulated product seeps into the treated plants, moving throughout the stem to reach the roots, effectively killing the weed within 24 hours.

Expel Turf Herbicide comes in a convenient squeeze-and-measure bottle, creating little handle-ment during application and lessening the possibility of product spillage.

Tools Needed

This product can be applied with a backpack sprayer, spray rig, boom and nozzle sprayer, or boomless application equipment.

How to Use

• Step 1: Determine how much Expel Turf Herbicide to use by measuring the square footage of the treatment area. To find this, measure the length and width of the treatment site in feet and multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 = acre). The application rate for cool-seasoned grasses will apply 4 to 8 oz. of Expel Turf Herbicide per 10 gallons of water per acre. For warm-seasoned grasses, use 8 to 12 oz. of product per 10 gallons of water per acre. Refer to the label for specific application rates.
• Step 2: Fill your selected sprayer halfway with water, add the measured amount of Expel Turf Herbicide, and pour in the remaining half. Close the sprayer tank lid and shake until the solution is well-mixed.
• Step 3: On a low-pressure spray, coat the plant base and soil surrounding the weed until wet. Allow 35 days to pass from the first treatment before applying a second application. Best results are seen when waiting at least 1 month after product application before sprigging, overseeding, or reseeding.

Where to Use

Expel Turf Herbicide is to be used on railroad, highway, roadside, pipeline, utility right-of-way, industrial areas, fence rows, non-crop sites, residential and institutional lawns, athletic fields, commercial sod farms, golf course fairways and roughs, in container and field grown ornamentals, cool-seasoned grass, and warm-seasoned grass.

Do not use within 50 feet of sinkholes, reservoirs, impounded or natural lakes, wells (including drainage and abandoned wells), intermittent/perennial rivers, and streams. This product should also not be applied to areas with ornamental bulbs or dormant non-woody perennials, nor on coarse soils (sand) or food-producing trees, vines, or plants.

When to Use

Use Expel Turf Herbicide when the turf is well-established or weeds are relatively small; typically, this will be in early spring, late summer, or fall. Apply on calm, warm days when the soil is firm and not moist.

Safety Information

Expel Turf Herbicide is safe to use around children or pets when used according to the product label instructions. Always wear the appropriate personal protective equipment (PPE) when mixing or spraying this product.

Do not allow children, pets, or other individuals to enter treated areas until the sprays have dried or 24 hours have passed since the application.

Special Considerations

St. Augustine grass and some varieties of bahiagrass, rough bluegrass, or zoysiagrass, particularly stress-weakened turfgrass, can experience temporary leaf surface discoloration (removed upon mowing) upon application of Expel Turf Herbicide.
