How long do I need to wait after fertilizing to overseed my lawn?

I Just put down Scotts with Halt, on the bag it notes that this can prevent new seeds from germinating. They advise waiting four months. Is this really true, do I really need to wait until August before overseeding? All answers appreciated.

1. Sorry, but the purpose of halts is to keep seeds from germinating!!! Yep.....you have effectively cancelled the need for seeding this year!
2. If they had to put it on the label then there is a reason why. Sorry, you are out of the reseeding game until the pre-emergent is no longer active.
3. "Cactus.." and "dogzilla" are right on. The "halt" in Scotts is a corn-based pre-emergent killer of seeds. You'll just be adding a thin layer of fiber to your lawn if you try and over-seed at this point.
