Who exactly are you addressing this comment to?

You.

Well you must have me confused with someone else.

Nope.

Because I was never
discussing using pre emergent for poa trivialis with you or anyone else
before talking to the agricultural extension.

You didn't read this part of the thread?

Hi Trader.
I may pull a remaining clump and take it to the local state agri
service for identification, as I've been curious as to exactly what
this is for awhile. Quack grass is on my list of possibilities too.

It might be quack if it hasn't gone to seed yet, or it could also be some
sort of bizarre annual rye, or blue...or, if it is or has seeded. (?)

As someone else has already suggested, the only way to attempt a control
of an annual grass infestation is with a late summer pre-emergent
crabgrass control product application. (the same product you'd use in the
spring)

You have to lay it down before the annual grasses
re-germinate....otherwise their whole life cycle starts over. (timing is
critical)

It's a real problem to deal with, if you're going for a mono-strand look.
