Per the product label for Prodiamine 65 WDG (Generic Barricade): Injury to desirable seedlings is likely if Quali-Pro Prodiamine 65 WDG is applied before the secondary roots of seedlings are in the second inch of soil (not thatch plus soil). To reduce the potential to injure overseeded turf, wait 60 days after seeding or until after the second mowing, whichever is longer, before applying Quali-Pro Prodiamine 65 WDG.
