After applying this product to my lawn, specifically to kill/prevent the crabgrass. When can I seed for new grass?
If the Barricade 4FL Pre-Emergent Herbicide (Prodiamine) was sprayed in early spring, then yes, you can overseed. The only time you can't overseed is if you apply the Barricade within 4 months of seeding.
