    Be careful of what you ask for. You may get it.

    Adding Pre-emerge to your Non-Select Grass Killer (Roundup) may give you close to 2 months but it is not a guarantee. The next step up is ground sterilizers that I will advise you to stay way from. Unless you are doing large areas or high volumes Stay with Retail products Like the Roundup long term product which has pre-emerge in it. I have never used that product and not sure of the exact name of it. But I have seen it on Tractor supplies shelves.

    first thing to pop into my mind was gly + oxyflourofen (sp?). I think this is what was in a product I used about 7 years ago... Groundclear Triox?

    I hope you will be applying this on your property only.

    There are a couple of new products on the market that combine a pre-emergent with glyphosate. I think Lesco sells 'Pro-deuce", a combination of prodiamine and glypohosate. Ortho makes a similar product using dithiopyr.
