Letter to Lawn Care Professionals and Golf Course Superintendents

Dear Lawn Care Professionals and Golf Course Superintendents,

I am writing to update you about the product return and refund program for DuPont™ Imprelis® herbicide. We have written to your distributor, who will be coordinating with you to ensure that all remaining full and partially full bottles of Imprelis® are returned. Once your distributor contacts you regarding this product return and refund program, please return all Imprelis® product to them within 10 business days.

After you return your remaining Imprelis® to your distributor, you will be given either a refund or credits, depending on your distributor’s policy. The EPA approved disposition plan suggests that you maintain records associated with Imprelis®, including but not limited to: 1) quantities used and returned, including product lot numbers 2) application records, and 3) purchase records.

If you have Imprelis® product remaining in mixes or spray tanks, please contact DuPont at 800-463-8039 for further guidance.

The following products are included in the program:

  • Imprelis® herbicide (D14616296) – 4.5 fl oz bottle
  • Imprelis® herbicide (D14563533) – 1.0 gallon bottle
  • Imprelis® herbicide (D14544159) – 2.5 gallon bottle

We regret any damage that the use of Imprelis® herbicide may have caused to trees, and we remain committed to working with you and all of our customers to promptly and fairly resolve problems associated with the use of this product.

We appreciate your help in this matter. Please let us know if you have any questions.
