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.
- Use only on the listed established grasses at their permitted rates. Fine fescue, tall fescue, St. Augustinegrass, bahiagrass, rough bluegrass and zoysiagrass can have cultivar-specific injury or discoloration.
- Several weed tables explicitly say control or suppression without identifying which applies to each weed. Those entries are shown as conditional activity, not 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.
