That's bogus. Preemergent controls prevent the seeds from sprouting
in early spring.

They do the same thing in late summer, brainiak.

This would be one of the ones that you spoke of in an earlier thread,
wouldn't it?

Yep. Most of them prevent grass seed germination first, some are better
than others at it.

rgr that. I was referring to those that constantly give out bad advice. ;)

That's bogus. Preemergent controls prevent the seeds from sprouting
in early spring. In order to kill the plants before they set seed in
summer/fall, use a crabgrass killer several times.

you are partially correct. preemergent controls prevent seeds from
sprouting, period.
Of course, you're right. However, in the late summer crabgrass plants
are mature and setting seed. We don't want those seeds to hit the
ground. So, we kill the plants. I may be wrong, but that's why Ortho,
Bonide and other companies produce "crabgrass killers". In my
experience they work very well when applied according to the directions.

Funny how he thinks applying it in late summer is no good, but applying
it several times is a great idea.

I didn't know pre-emergent herbicide could read a calender.... someone
better tell preen. :)

When are we supposed to apply it
then, 3 weeks in a row in April? LOL

Know what too much will do? Root prune the desirables.

Like I told you before your extension guy did, timing is critical with that
approach. Too soon can root prune, and too late won't work. You'll still
end up with some of it.

If you follow the thread, the discussion about applying pre emergent
again in late summer was to control poa trivialis, not crabgrass.

You.



Well you must have me confused with someone else. Because I was never
discussing using pre emergent for poa trivialis with you or anyone else
before talking to the agricultural extension.

Crab grass!
 

OK, I see it now. I think what had me confused was I didn't know it
was poa trivialis until 2 days ago and was thinking of the discussion
in the context of what works specifically for that. When we were
discussing it before, no one knew what it was, but the advice you gave
does work as one of the avenues of attack for this too.
