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.
- This is the 5% quinclorac / 1.6% sulfentrazone CA formulation, not the separate, higher-strength Solitare WSL registration. Match the exact EPA number and ingredients.
- Use on established listed turf. Tifsport bermudagrass and Zeon zoysiagrass have added discoloration precautions. Lower weed rates give suppression rather than control.
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.

Weeds and coverage
“Conditional activity” flags undifferentiated control/suppression or unresolved weed identity and label conditions. “No activity” is an explicit label entry. An absent weed is not evidence that the product cannot affect it.
