Although the label does not specify, we recommend that you use Bayer Advanced 2 in 1 Moss and Algae Killer RTS on established turfgrass for the least risk to your grass. Established turf is generally considered turf that has been growing for at least 4 weeks, or until after the 2nd mowing (whichever is longer). The light rinse is intended to reduce risk to desirable plants since this product could cause burn on plants, especially in hot temperatures. If you have not yet seeded areas that have moss that needs to be treated, then we recommend that you first control and remove the moss, then you can seed at least 5 days after treated, if needed.
