Thanks for the reply, Timothy. The product in question was delivered
through a pump sprayer. This is very embarrassing as I am a carpet
cleaner owner/operator. My stuff is labeled in the van...So do you think
the same will go as far as what you said before since it wasn't diluted
much-if at all? I am anxious to get seed down since we had a late spring.
Thanks for the low-down on the #2 of your post. It makes total sense.

I firmly believe that the herbicide is no longer active. If it was truly
round-up, even at concentrated levels, it should be completly washed out
of the soil by now. Round-up has a half life of 2 to 4 weeks... so it
would be totally inactive with in 4 to 8 weeks.

What you can do at this point...
You could spray the weed/lawn area with round-up ( I personally prefer
finale as a herbicide due to it's short half life ), wait 2 weeks and
re-seed.

When I can, I try to use chemicals that are less harmful to people and the
enviroment. The product Finale is a herbicide that containts
Glufosinate-Ammonium. It ( in my humble opinion ) is safer to the public
and the enviroment than round-up due to it's short half life and due to
the bacterial break down of the product in the soil. It's less likely to
move through the soil and contaminate the ground water. Granted, finale
doesn't have the longevity of round-up but if your looking for longevity
you should be looking for a pre-emergent such as 2,4-d in my opinion.

I decide on which herbicide to use using a couple different factors.
For light weed infestations or if your looking just to 'knock down'
weeds/grass, then I select horticultral vinegar. If the outside temps are
not high enough for the vinegar ( 70 or above ) I tend to use finale with
an added herbicide sticker. For heavy infestations or brush, I tend to use
a product called crossbow. It is in a nut shell triclopyr,2,4-D and
kerosene. It is completely nasty stuff but sometime nessasary.
Good luck with the lawn.....
