Product Overview
Atticus Empero Nutsedge Killer is a highly effective turf herbicide containing 75% halosulfuron-methyl, designed to control tough nutsedge in established lawns, ornamental turfgrass, and landscape areas. It works by traveling down to the root system tubers for complete weed kill. Gentle on most warm- or cool-season turf, it's easy to measure and mix, and is rainproof after 4 hours. People and pets can re-enter treated areas once dry.

Application Instructions
Apply the mixed solution to areas affected by nutsedge. Ensure thorough coverage of the weed foliage.
- Apply to established warm- or cool-season turf, including bluegrass, fescue, Bermudagrass, and zoysia.
- Ensure the entire leaf surface of the target weed is wet with the spray solution.
- Avoid double spraying areas to prevent thinning of grass. Using a blue dye (not included) can help track sprayed areas.

Post-Application Care

- Pets and people can re-enter the treated area once the spray solution has dried.
- The product is rainproof after 4 hours, meaning it will remain effective even if rain occurs after this period.
- Avoid watering or cutting the lawn for 2-3 days after application for optimal results.

Troubleshooting
If nutsedge persists after initial application, consider the following:
- Ensure proper mixing ratios were followed, including the use of a surfactant.
- Verify that the entire leaf surface of the nutsedge was thoroughly wetted during application.
- Check weather conditions; avoid application if rain is expected within 4 hours of treatment.
- For very dense or stubborn nutsedge, a second application may be necessary after a suitable interval as per label instructions.
