Imprelis® Facts

What is DuPont™ Imprelis®?

Imprelis® is an herbicide created by DuPont for professional use on residential, industrial and institutional lawns and on golf courses.

What is the problem related to Imprelis®?

Some customers who used Imprelis® in their landscaping businesses and on golf courses have reported injury to some species of trees, primarily Norway Spruce and white pine, but DuPont has also received reports of problems with other species.

How widespread are these reports?

The reports of problems appear to be primarily concentrated in a geographic band that includes Minnesota, Michigan, Indiana, Ohio, Pennsylvania, New Jersey and Wisconsin. While most properties treated had successful weed control, we are committed to continuing to work with every customer who experienced problems related to Imprelis®.

We encourage anyone with indications of tree injury to contact their lawn care provider and to return to this website for updates. On September 6, DuPont began a process to fairly resolve claims for impact on trees that Imprelis® herbicide may have caused.

Is Imprelis® safe for humans?

Imprelis® poses minimal risks to people or pets.

Does Imprelis® affect composting?

Clippings from grass treated with Imprelis® cannot be composted. As a precaution, if you dispose of a tree that may have been injured through the use of Imprelis®, do not chip the tree for use in mulch or compost.

If my tree is damaged, will it return to health?

We expect the majority of trees to recover, but it takes time. Lawn care professionals have received information about general care practices to help trees recover. More information can also be found on this website.
