    Most labels say not to plant seed for 3 to 4 weeks. Does anybody have any experience with seeding sooner and did the seeding suffer because of it?

    Quali-Pro 3D applied on 8/3/18. The clock is ticking for my seeding job, and I'm wondering if I should push the envelope a little.

    Thanks Riggle, I thought you had posted about this before, but I couldn't find it in search.

    I think I will kill it now and wait two more weeks until I seed. I have seeded PRG sooner without noticing any problems, but I don't want to have to do this seeding twice.

    Quinclorac is 7 days. Most of your broad leaf herbs are 2 weeks minimum. I prefer 6 weeks myself, depending on rainfall.

    We are almost in prime seeding time here in Connecticut. At this point, I just use round up to kill weeds in areas to be seeded. Wait time for gly is "after it's dry"

    My only experience sort of like that is I once gave a weedy / sedgy area a full dose of sulfentrazone — then the sod unexpectedly and finally after a long wait was delivered next day :eek:. Sod placed and irrigated per usual. No ill effects detected.

    Just for future reference Tenacity can be used prior to seeding if I'm right
