Imprelis Herbicide Tree Damage Class Action Lawsuit Filed Against DuPont

A class action lawsuit has been filed against DuPont over its Imprelis Herbicide, which is reportedly killing or severely damaging trees in addition to the weeds it is designed to fight. 

The Imprelis herbicide class action lawsuit was filed on July 14 in the U.S. District Court for the District of Delaware by several Michigan country clubs and property owners, including Washtenaw Acquisition, LLC, Polo Fields East, LLC and Polo Fields Golf & Country Club.

The environmental tort lawsuit seeks to represent any property owners who experienced tree damage or tree death after using DuPont’s Imprelis herbicide. The complaint is divided into two classes, one specifically for Michigan landowners, and another class for landowners nationwide.

Imprelis is an herbicide designed to kill broadleaf weeds. It was approved by the U.S. Environmental Protection Agency (EPA) in 2010.

However, according to the lawsuit, property owners almost immediately discovered that Imprelis side effects killed mature landscape trees just weeks after application, including Norway and Colorado spruce, white pines and other evergreens. The needles and branches of the trees turned yellow and curled up as the trees died. Some estimates put damages caused to those types of trees in the millions of dollars for property owners.

Last month, DuPont issued a warning not to use Imprelis on properties with Norway spruce or white pine trees (PDF) on the property or nearby. However, the lawsuit claims that by then professional lawn care services had already applied Imprelis to thousands of lawns and commercial properties throughout the United States. DuPont said in the warning that it was still investigating the Imprelis problems.

The lawsuit accuses DuPont of failing to properly test Imprelis and charges the company with consumer fraud, unjust enrichment, negligence, product liability, and property damage. The lawsuit seeks restitution for three times the amount of the damages incurred by property owners who used Imprelis.

    We have Underwood Lawn service. they applied imprelis in their spring applications of lawn care. We now have mature large trees dead, completely. Underwood has given us their insurance company to contact. Their local company (Kapnic Ins) said we'd have to contact the Hanover adjuster, so we did. The Hanover adjuster is refusing to even visit/give us a claim number, because they say it is Dupo[Show More]We have Underwood Lawn service. they applied imprelis in their spring applications of lawn care.

The Hanover adjuster is refusing to even visit/give us a claim number, because they say it is Dupont's fault. We are being held captive (while attempting to put our home on the market for sale) to KEEP the dead trees on the property till a solution comes about. Perhaps we need to talk to someone about Dupont directly, tho our local landscape service SHOULD be our responsible party. We seem to have no where to turn now
