    Hi Cindy

    What I meant to say and perhaps was not clear, trees equal to or less than 20 feet in height are not being treated fairly in the DuPont resolution process. In Michigan, for example, I contacted about 5 or 6 reputable tree sale operations and received prices for trees 20ft and under. I calculated the cost of replanting and disposal of toxic materials etc. Then I compared those values to several Resolution agreements I was asked to review. In each case, I had to recommend that the property owner get local pricing, consider the extra removal and installation costs, repair to turf, landscape and hardscape features etc.

    I know what Dupont is offering for trees less than 50 feet tall for some species. I don't know if DuPont is using this valuation scale for all species.

    I do know, for a fact, that Imprelis is still active in the soil and still causing injury to trees including many hardwoods. And yes, your roses may be impacted. I have seen many damaged roses with odd shaped leaves and yellowing consistent with a damaged root system.

    Do not discharge grass clippings on flower beds or around trees. Blow the clippings away from plants if possible. Remember, DuPont has warned up not to mulch with grass clippings, well, if you discharge the clippings onto flowers what do you think the results will be? And why is DuPont warning everyone to completely remove all plant material from trees and plants they are cutting down? And warning not to put in compost or mulch sites? Think about it? They know their chemical Imprelis is still active and cause injury.

    Cindy. Ask yourself a few questions:
    1. Where was the Imprelis applied?
    2. What plant organ was first to contact and remain in contact with the toxin?
    3. If the roots were damaged, probably more than the canopy, will they be able to absorb nutrients or water as efficiently as non treated trees?
    4. What is going to happen when the temperature rises and the trees need more water?
    5. Why are we seeing so many "yellow or light green" tree and plant leaves on Imprelis treated property?

    If the roots are injured, then they simply won't function normally. You are going to see nutrient deficiency problems, wilting, die back in the tree canopy etc.

    We have figured out the first offer is lower than it should be.

    I'd like to know the value of the larger trees also, mine are mostly 30 - 40 feet tall. I will be doing a counter offer, I've had more damage since the first report and dupont's site visit wouldn't include since it wasn't on the original report.

    I'll get some pictures tonight of my deformed blackberry leaves and my yellowed roses. My knock out roses stopped blooming, just dead blooms.

    No doubt that the Imprelis is still active, new growth on my trees are deformed and then dies.

    Are you an arborist? Attorney? LCO? Wondering why you are checking resolutions?

    Almost every tree we own, is dying or deformed. I stuck some tomato plants out near my worst trees, will keep a picture diary.

    Starbuy listed some very interesting information concerning the half life of Imprelis in a recent post. This information is taken from the following EPA document which can be downloaded from the web.

    EPA-HQ-OPP-2009-0789-0014[1] Registration

    Look on page 13 - 14 concerning "Environmental Fate". You may want to read other sections as well. There are about 2.54 cm per inch for conversion purposes.

    I just read that settlement agreement you posted. DuPont is lying about imprelis impacting ground water.

    Here is what they were quoted as saying:

    Aminocyclopyrachlor does not pose significant risks to human health or groundwater contamination, DuPont spokeswoman Kate Childress said.

    "Contamination of well water by Imprelis is highly unlikely," Childress said.

    This is what their EPA Regsistration document says on page 13:

    1.3.2. Environmental Fate
    Aminocyclopyrachlor is non-volatile, highly soluble in water, and highly mobile to mobile in
    soils. Dissipation in the environment is expected to occur predominantly via aqueous photolysis, runoff, and leaching. Terrestrial field dissipation occurred with half-lives ranging from 22 to 126 days. Aminocyclopyrachlor was detected at soil depths of 70 – 90 cm at 365 days, indicating that leaching of residues into groundwater may occur.

    I wonder if I should send a copy of this to DuPont? What don't they understand about being "highly mobile" in soils? That means it moves through soils, downward and laterally, very easily. That is why Starbuy had injury on his property because it moved off the target property onto his. I have seen and photographed many properties with injury far from the application site.

    This truly scares me about our water. We live on over a acre of land and yes we have well water. I have 2 children who drink water daily from our tap from taking to school water bottles everyday to the bottles they fill for their sports not to mention my husband coaching my sons team and all the water bottles he has filled over and over during the last year to provide for those 17 kids on the team!!!!! The water from my well.
    I am terrified to think of the effect it could have on my family!!!!
    Cindy could you please provide the email address you have when emailing Dupont.
    Starbuy, do you have well water also? If so have you been using it over the past year.
