    i have heard now that dupont is only seeing damage to white pines, and not spruce trees.

    we need dupont in here to start clarifying things before this gets out of hand with hearsay!!

    i am waiting for them to call me back

    Yes, yes they do. They need to get a presence somewhere on-line especially if this is the only national forum that is really discussing the matter.

    They are watching these threads, I can guarantee it.

    We are seeing damage on White Pine, Norway Spruce and Deodora Cedars.
    Nothing on Colorado Blue Spruce or Firs.

    Our field reports show 4 separate customers asking if we are doing something different as their dogs got sick. Still researching that one.

    Thats real nice. The msds and the rep pretty much came across as this being a safer pesticide. Wow, this stuff worked great on thistle, bindweed, charlie, violets, clover, however all these adverse aspects is really starting to concern me a lot.

    sorry for the low-quality picture, taken with cell camera.
    I took these today. They are spruces on a lawn I sprayed on 4/11/11 with Imprelis. Also seeing white pine damage on several properties. Going back in a few days with a real camera, will post more.

    Here's a spruce in a bed next to a driveway. There is just the 1 ft-wide strip of turf between the driveway and the bed, nothing behind or around it. Tips are just starting to turn brown. Mature tree, about 20-25 ft tall. Hopefully it doesn't get any worse.

    I've looked at several lawns I sprayed w/ Imprelis, haven't seen any damage to Blue Spruces yet.
