Chemistry in the news

                According to the Environmental Protection Agency website, the scientist at the EPA have registered a new nematicide alternative to a list of nematicides (Milbourn, EPA website). The chemical they are switching out is called fluenesulfone, which “has a lower risk than the methyl bromine that they once used in insecticides. This chemical does not have the unintentional side effects on other plants (Kearn, Dillon, Ludlow, Abstract). Fluenesulfone is a part of the chemical group called floroalkenyl thioester group. (Abstract). The image below is the chemical formula for the new nematicide for crops.
