    Originally searching around the net for more info, this and the Imprelis timeline thread were popping up in search engines.

    Now I don't see them when I do a search. Don't know if it's me or if something is up.

    Coincidence ? ;)

    It's DuPont. They're flying around in black helicopters zapping these threads from search engines.

    Just kidding!
    I googled Imprelis Damage and saw both threads. But I was on the Harrell's website earlier tonight and didn't see Imprelis in their products anymore.

    we do some sub work for Brickman and they sent an email to all subs this afternoon saying Imprellis is NOT to be used on any of their properties and if it was used already this spring, it was to be reported to two contacts they gave. They said "Imprelis may cause severe damage to deciduous and evergreen tree". After seeing these pics, Im so glad I stuck with our 3 and 4 way products. Sorry guys if you are having to deal with any of these complications.

    Can't hurt this tree much more than it already is. Canopy is so thin you can see right through the tree......Cut that sucker down.

    I only mow and am seeing what looks like this on all kinds of pines in Southeastern MI. 4 to 6 weeks ago we had alot of rain when companies were treating lawns. I posted what I am seeing in the Network section under Michigan LCO's. Is there any cure or way to save the pines? Some homeowners are being told it is a fungus and are being sold a 3 application treatment and that the pines can be saved. All the pines 20 to 30 or more and all sizes 5' to 50' on 1 acre lots are affected.

    You can't tell from the angle of the picture, but that's a big bed with 4 or 5 old spruces and a pine in it. Also a visual barrier between their house and the back of the neighbor's garage.
    I've been spraying the lawn and trees at this property for 20 years, never had a problem. Until Imprelis.

    Some of the damage I am seeing was sprayed on 5/18.

    Got my first call yesterday. A Norway spruce showing signs of damage. the customer had a tree specialist look at the tree and send a sample off to Purdue. it was pesticide damage but said the tree looks like it will recover. I have almost 5 gal of Imprellis, think I'm gonna call my rep today and trade out the unopened jug for another herbicide.
