Surflan AS Herbicide is not labeled ofr use in hay fields or pastures where animals graze. You would not be able to use the area for hay for at least 1 year. Pastora is the only pre-emergent we carry labeled for use in select hay field types. Please refer to the product label to confirm it would fit your needs.
