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.
- For home lawns only, on well-established, non-stressed turf. Check the exact grass, cultivar, reseeding and application restrictions.
- Use the lawn weed tables only; ornamental plant lists are excluded. The detailed tables do not distinguish control from suppression for each species; the Use Information section makes some explicit control claims.
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.
