Products with Prodiamine* (aka. Barricade)......labels say you must wait 4 to 7 months to seed, and that would prevent me from overseeding end of Sept/first week Oct.
If the Prodiamine is active, your seed won't germinate. Whereas with Dimension, after some weeks, you can seed (fescue). "

This is why you "Slice Seed" rather that seed/soil contact.

When you break the 4 month Barrier of the Pre with the mechanical tines, seed will germinate.

I've nothing against slice seeding. In fact I'd consider a Turfco LS-22 if they become available again, or a Billy Goat OS5.
Anyway, I'm BIG on lawn prep prior to overseeding. But to date I haven't slit seeded though I'm not against it.

With all due respect, I humbly say that I am not fully convinced that slit seeding allows one to "break the 4 month barrier of the Pre [prodiamine].......seed will germinate".

Problem I see is poa is a cool season grass it’s annual blue grass as I am sure you all know. We have a tough enough time trying to keep it out of warm season grass I can’t imagine anything that’s going to work well on cool season. But I’m watching to learn.

Also more of a question Prodiamine is a cell division regulator. It stops mitosis of the cotyledon. I don’t see how any mechanism in the mechanical realm will prevent this from occurring if it’s already in the soil profile. Happy to be proven wrong on this. To me it’s more chemistry than anything I could do once it is down.

There are many tools (Negate, Momentum) for fighting Poa in warm season turf. But not so for cool season (eg.tall fescue).
Poa and grass are so similar it's challenging to kill one but not the other.
Poa is like a perennial......while the above-ground plant dies in July/August, it returns in the fall.
I've tried Ethofumesate (RightLine Etho 4 SC) but it appears to do nothing. I mixed it at 1 oz per gallon. I tried it 21 days apart in Jan/Feb, but should have Dec/Jan....my mistake.
I haven't tried Bayer's ethofumesate product Prograss.
Has anyone tried pricy Poacure SC from Korea? (PoaCure® SC (16 fl oz)). Inconveniently, one can't over-seed within 45 days of the last application, or apply PoaCure within 12
weeks of over-seeding.

How about Tenacity and maybe mixed with Dismiss
