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.
- Creeping bentgrass, bermudagrass and seashore paspalum are only marginally tolerant; injury and reduced weed control can occur. Read their special directions before considering use.
- For labeled weeds, use the required spray additive, growth-stage and sequential-application directions. Many uses are not allowed in California.
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.
