As alleged in the complaints, Imprelis, which is meant for killing broadleaf and hard-to-control weeds, including dandelion, clover, plantains, ground ivy, and wild violets, was released by DuPont in October 2010. The herbicide was originally approved in part because of its low toxicity towards mammals. However, since Imprelis’s release, lawn care professionals and land owners in a reported 22 states have complained of tree damage, including brown spots and shedding of leaves, in connection to the substance. Last week, DuPont announced that it plans to stop selling Imprelis and that it intends to issue a recall to remove Imprelis from the market.
On Thursday, August, 4, 2011, DuPont released a statement, saying that it is working closely with the U.S. Environmental Protection Agency on “the most effective way to implement our recommendation of a voluntary suspension of sale of DuPont Imprelis herbicide, and a product return and refund program.”
