"DuPont To Recall, Stop Selling Herbicide"

"DuPont said it plans to stop selling and recall its widely used Imprelis herbicide after customers and several lawsuits complained that the treatment has killed thousands of trees.

In a statement on Thursday, DuPont said it is in talks 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.'

It said the talks are intended to 'assure full transparency of important scientific data' regarding Imprelis.

The EPA conditionally approved Imprelis for sale last October, but DuPont this year began receiving many complaints that the herbicide may be lethal to mature landscape trees."
