A new version of a weed killer used on corn and soybeans has now been approved for use in several states, however not yet in Missouri. While officials are trying to get it approved in 10 states including Missouri, critics are calling for its removal citing it being harmful to public health. The EPA announced this past Wednesday that is has approved the use of Enlist Duo, a new version of an herbicide used since the 1940’s. Seeds are engineered to resist the herbicide so farmers can use to kill weeds without damaging crops. Critcs believe it has not been tested enough to be approved for public use and wants the EPA to pull it back until it’s been tested to their liking. The EPA is setting a 30 foot buffer zone where the herbicide cannot be sprayed.
