Expel Turf Herbicide, manufactured by CSI, is a 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 then moves throughout the stem to reach the roots, effectively killing 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

Expel Turf Herbicide can be applied with a backpack sprayer, spray rig, boom and nozzle sprayer, or boomless application equipment.

Applications by helicopter can only be made to railroad right of ways.

How to Use

• Step 1: Determine how much Expel Turf Herbicide to use by calculating the square footage of the treatment area. To find this, measure the length and width of the treatment site and multiply (length X width = square footage). For acreage, take the square footage and divide it 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: In your selected sprayer, fill halfway with water, then add the measured amount of Expel Turf Herbicide, and pour in the remaining half of water. Close the sprayer tank lid and shake until 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.
