SpeedZone Lawn Weed Killer Concentrate is labeled to eradicate buttercups and many other listed broadleaf weeds selectively in listed established lawns. It can be applied to the newly seeded areas after the third mowing. If the product was already applied, you can reseed two weeks after the application per the instructions on the product label. It can be applied at the same time as a fertilizer not a weed and feed type product.
