"DuPont was ordered by the Environmental Protection Agency on Thursday to stop selling and recall its Imprelis herbicide, following thousands of complaints that the treatment kills trees."

"

The order came after the EPA in June began getting reports from state agencies of damage to evergreens linked to Imprelis, which DuPont had marketed to control weeds in recreational areas such as golf courses and commercial properties such as sod farms.

According to the agency, DuPont has submitted more than 7,000 reports of damage or death to such trees as Norway spruce and white pine, as well as test data confirming a link between Imprelis and tree damage. The EPA said it approved Imprelis for use last August."
