Imprelis Kills Trees. Its Effects on Groundwater Have Not Been Determined.
The highly touted herbicide Imprelis, from DuPont, has been found to kill trees and is not approved for use in New York and California because, among other problems, it leaches into groundwater.
Some 30,000 homeowners, golf courses, municipalities and landscapers have submitted claims blaming Imprelis for tree deaths, with more claims still trickling in.
DuPont would not estimate how many trees have died from exposure to the chemical, but experts on trees say it is likely in the hundreds of thousands.
