    I am sure this has been gone over but I spent about 30 min. using the search feature with little results.

    I have a home that has an event in 4 weeks, we have some patches of Poa in the rye. I would like the lawn to look perfect so I need a product or method of eradicating the Poa without disturbing the Rye. Cost is not an issue.

    I also read to apply a pre emerg in the fall as a preventative but I can't do that as I am over seeding the winter rye in the hybrid Bermuda. So how do I control this annoying little weed?

    I cannot count on temps being consistently over 80 for mother nature to do her thing.

    I think Prograss or ethofumesate will kill Poa and many other grassy weeds in rye. I thought I saw it labeled for use in dormant bermuda overseeded with rye on the Bayer website.
