Sod over Halts

    Just contacted by a potential customer wanting sod (approx 10,000 sq ft). It seems that he had a new pool installed and seeded AND applied Scotts with Halts Crabgrass Preventer. I didn't ask why. Well he realized his seeds are not growing and he made a mistake. He wants grass ASAP. My question is can sod be laid on the Halts after it is tilled under?? Or is he waiting until the fall??

    Given the stupidity of what the clients done so far, it's probably safe to assume he's over applied the Halts too. That said, tilling would cause the barrier to break & the vapors that don't dissipate will at least be diluted to the point where the sod will be OK.
    In other words: Go for it.

    Tilled in should be OK,

    Most crab. pre-emergents do inhabit root development on sod.

    I think I would worry more about the "DIP"watering enough to keep it alive.

    Hang in there!

    Thanks for the info guys I was thinking the same thing but did not know for sure. Until....I called Scotts yesterday and was told it would be 4 months for the Halts to breakdown. This would apply to reseeding AND laying sod.

    Thanks again,

    Any tiller worth it's weight in salt is going to churn soil down to 10" or more. Pendimethalin sets a gaseous vapor vapor in the top inch of soil. I'll repeat, tilling that barrier will cause much of the gas to dissipate. What's left will be diluted by a factor of 10. Halts label does NOT require a 4 month wait even at the full rate so the Scotts rep was covering the companies butt.
    If you're really worried, Activated Charcoal definately will work, but I still don't think you need to go that far.
    Just my opinion though.
