Label scope and conditions
EPA-accepted master label, residential-lawn use only. Marketed labels may use a subset of these claims. Match the registration and formulation, and follow the label on your container; this reference is not a replacement for it.
- Professional applications to residential lawns are labeled. St. Augustinegrass is restricted to sod farms and is excluded here. Some uses are not registered in California.
- Spot and broadcast directions differ. Follow treated-area limits, weed-growth stages, grass-specific directions and required adjuvant instructions; this product does not control broadleaf weeds.
This page summarizes coverage and does not provide application rates or mixing instructions. Use the complete label on your container for directions, protective equipment, reentry, environmental precautions, and restrictions.
