A class action settlement provides money and other compensation for damage to trees and other vegetation that was caused by an herbicide (weed-killer) called Imprelis®.

Imprelis® was applied by lawn care professionals on residential and commercial properties, as well as by licensed "self-applicators" on golf courses and other properties. Imprelis® was approved for application across the country - except in California and New York - between August 31, 2010, and August 21, 2011.

This Settlement provides compensation to three groups, called classes, of individuals and businesses. Select one of the classes for more details.

Notice of Final Settlement

The Settlement is now final.  The settlement became final on June 16, 2014.  A notice of Final Settlement has been sent according to the terms of the Agreement.  New claims are no longer being accepted, and for many property owners, the deadlines for objecting or appealing a Claim Resolution Agreement (CRA) has passed.  The CRA sets forth the deadlines for objecting/appealing if you disagree with its terms.  Those who received a CRA recently may have one or more of the following options:

(1) submit a written objection to your CRA by the deadline set forth therein; or (2) file a timely Notice of Intent to Appeal to the three arborists Appeals Panel. 

More details about options available to class members are set forth in these FAQs.

If you have not received a response from DuPont concerning an existing claim or warranty claim, please be advised that DuPont is continuing to process existing claims and conduct site inspections.
