Marketed by DuPont de Nemours and Co. as an environmentally friendly and safe weed killer, the chemical is being blamed for killing more flora than just weeds.
The product was approved by the EPA in 2010, and marketed in 2011. Mature trees and shrubs in mass are being killed as a result of the lawn applications. Conifers appear to be especially susceptible. At least that is what several homeowners and businesses across the nation are claiming. As of mid-February, there were 29 lawsuits filed in Waukesha County alone.
Projections from arborists and landscapers predict the numbers could be in the thousands across the country, as negative reports from at least 22 states are being filed. The effects are just now starting to surface from applications done in early 2011.
The U.S. Environmental Protection Agency has ordered DuPont to stop the sale of the herbicide until further notice. DuPont has indicated that grass clippings should not be used as mulch in or around trees or gardens, and recommends that homeowners wait at least six months to replant trees.
Concerned homeowners can call DuPont’s Imprelis hotline for more information at 1-866-796-4783.
Have any of our readers been affected by this application? I would be interested in seeing any comments or reports our landscaping readership may have to offer.
