Becher from Uniontown Pa writes
Prodiamine 65 WDG (Generic Barricade) can injure desirable seedlings if applied before the secondary roots of seedings are in the 2nd inch of soil (not that plus soil). To reduce the potential of injuring overseeding turf, wait 60 days after seeding or until after the second mowing, whichever is longer, before applying Quali-Pro Prodiamine 65 WDG.
