Broadleaf Weed Herbicide Devastating to Trees
A herbicide produced by DuPont called Imprelis has been field tested by 25 major universities and registered by the Environmental Protection Agency in 2010 as a selective broadleaf weed herbicide.

The herbicide, which costs more initially, would have minimized the use of herbicides overall and seemed to be a good choice for lawn care service providers. Effective weed killer for lawns, it has also killed or damaged thousands of tress nationally.

Dupont has taken responsibility for the damage Imprelis has caused and has established a claim process. The EPA removed the product from the market a year ago and is now conducting an independent evaluation of the herbicide. The EPA said the herbicide “poses a low risk to both humans and non-target terrestrial and aquatic organisms, except for plants.”

Dupont has received more than 33,000 claims from homeowners and golf course operators who believe they have trees that were injured or killed by Imprelis.

Common Aquatic Bacteria Responsible for Fish Kill - Test results from fish sampling suggest the recent Spofford Lake fish kill resulted from the presence of a common aquatic bacteria combined with a time of year when fish were stressed from spawning activity and war water temperatures. Test results showed that no virus was present in the fish tested and that the bacteria found was Aeromonas Hydrophila. According to Fish Health Center Staff, this bacteria only becomes lethal to fish when there is another stressor to the fish. In some cases, the bacteria can infect a single fish and then multiply rapidly, causing a substantial fish kill.
