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 Kentucky bluegrass, fine fescue, perennial ryegrass or tall fescue. Do not use on unlisted warm-season grasses.
- Apply to actively growing weeds at the label’s early growth stage and permitted temperatures. Dallisgrass and nimblewill control require a second application after the labeled interval.
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.
