Will an application of Bayer Advanced All-In-One Lawn Weed and Crabgrass Killer one week after seeding prevent my new grass from establishing?

I seeded my yard 1 wk ago. 2day my roommate cut & then sprayed while I was at wk. Will this prevent my new grass from coming up?

Answer:

You should not apply Bayer Advanced All-in-One Lawn Weed and Crabgrass Killer to newly seeded areas until after the fourth mowing. Cutting new seedlings before they are established - plus herbicide application - puts extreme stress on the seedling turf and will injure or kill it.
