HOUSTON (ICIS)--The US Environmental Protection Agency (EPA) on Thursday issued an order to chemicals major DuPont to immediately halt the sale, use or distribution of the company’s Imprelis herbicide.

The herbicide, marketed to control weeds, has been reported to be harming a large number of trees, including Norway spruce and white pine, the EPA said.

Last week, DuPont already voluntarily suspended sales of Imprelis and announced that it will soon conduct a product return and refund programme. The company also set up a web page and a telephone hotline to provide information and updates concerning Imprelis.

DuPont spokesperson Kate Childress said, "In light of recent reports of tree damage related to the use of Imprelis we are conducting ongoing broad scientific and stewardship reviews of our data, label directions, and scientific analyses and sharing that information with the EPA. We remain committed to our customers’ satisfaction and will take all necessary steps to ensure that objective."

The EPA’s order follows an investigation into why a large number of evergreens and other trees have been harmed following the use of the herbicide, the agency said.

The EPA is still evaluating whether these incidents are the result of product misuse, inadequate warnings and use directions on the product’s label, environmental factors or other possible causes, it added.
