When it comes to tackling stubborn sedges and Kyllinga in your warm or cool season lawn, Halo Select is a must-have for both DIYers and lawn care pros. This targeted, easy-to-use herbicide offers reliable control over some of the most persistent grassy weeds. Here’s what you need to know about using Halo Select to keep your lawn healthy and sedge-free.
What Is Halo Select?
Halo Select (active ingredient: halosulfuron) is a selective, post-emergent herbicide designed specifically for controlling sedges—like yellow nutsedge, purple nutsedge, and Kyllinga species. Available in convenient single-use pouches or larger bottles with a measuring scoop, Halo Select makes mixing and application simple for DIYers. It’s safe for use on Bermuda, St. Augustine, Zoysia, Centipede, and Bahia lawns, as well as Kentucky Bluegrass, Perennial Ryegrass and Fescue.
What Weeds Does Halo Select Control?
Halo Select is highly effective against:
- Sedges: Yellow nutsedge, purple nutsedge, and green Kyllinga.
- Certain Broadleaf Weeds: (Check the product label for a full list.)
This makes Halo Select a go-to solution for those tough, grassy weeds that other herbicides often miss.
When Should You Apply Halo Select?
Timing is key for effective sedge control:
- Post-Emergent Applications: Apply when sedges and Kyllinga are actively growing and have reached the 3–8 leaf stage for best results.
- Warm-Season Lawns: Use on Bermuda, St. Augustine, Zoysia, Centipede, and Bahia. (Always check the label for specific turfgrass tolerances.)
- Cool-Season Lawns: Use on Kentucky Bluegrass, Perennial Ryegrass, and Fescue. (Always check the label for specific turfgrass tolerances.)
- Temperature Considerations: Halo Select works faster in hot weather (expect results in about 15 days) and a bit slower in cooler temps (up to 21 days or more).
How to Apply Halo Select
- Choose the Right Pack: One 13.5-gram pouch treats 1,000 sq ft and includes surfactant. The larger bottle covers up to 43,500 sq ft (1 acre).
- Mixing: Add the entire pouch (or one scoop from the bottle) to 1 gallon of water. For the larger bottle, add a non-ionic surfactant if not included.
- Application Method: Use a battery or pump sprayer for even coverage. Blanket spray for widespread sedge or spot treat as needed.
- Watering In: Do not water in after application—let the product sit on the foliage for best results.
- Tank Mixing: Halo Select can be mixed with other herbicides like Image, Celsius, or BioAdvanced for broader weed control.
Integrating Halo Select Into Your Lawn Care Routine
- Monitor for Sedges: Regularly inspect your lawn for the telltale signs of sedges and Kyllinga—upright, shiny, light-green blades that grow faster than your turf.
- Combine with Good Practices: Healthy mowing, watering, and fertilization help your lawn recover from weed stress and resist future invasions.
- Patience Pays Off: Halo Select works slowly but effectively—give it time to do its job.
Safety and Environmental Tips
- Keep Children and Pets Off Treated Areas: Until the spray has dried.
- Avoid Drift: Do not spray on windy days or near desirable plants.
- Storage: Store in a cool, dry place away from sunlight and out of reach of children.
- Check Local Regulations: Some products may not be registered for use in all states—verify before applying.

Halo Select is your best ally for sedge and Kyllinga control in warm and cool season lawns, offering targeted, professional-grade results with easy DIY application. By understanding when and how to use it, you can keep your lawn looking its best—free from those pesky, persistent weeds.
