  • U.S. approves use of Bayer weed killer for five years

    OCTOBER 27, 20204:00 PM UPDATED AN HOUR AGO

    By Tom Polansek

    CHICAGO (Reuters) - The U.S. Environmental Protection Agency said on Tuesday it will allow farmers to spray crops with weed killers based on the chemical dicamba that are sold by Bayer AG BAYGn.DE and other companies, after a U.S. appeals court blocked sales in June.

    The decision is a boost for Bayer, which has been hammered by lawsuits over various chemicals in the United States since acquiring seed company Monsanto in 2018.

    The EPA re-approved for five years Bayer’s XtendiMax, a popular dicamba-based herbicide that is sprayed on soybeans and cotton genetically engineered to resist it. It is known to drift away and damage other crops that are not resistant to it.

    National Institutes of Health Study Links Dicamba, Increased Cancer Risks

    Findings Come As Spraying of Drift-prone Herbicide Ramps Up in Midwest, South

    WASHINGTON— Researchers at the National Institutes of Health have found that use of the pesticide dicamba can increase the risk of developing numerous cancers, including liver and intrahepatic bile duct cancers, acute and chronic lymphocytic leukemia, and mantle cell lymphoma.

    Researchers at the National Institutes of Health have found that use of the pesticide dicamba can increase the risk of developing numerous cancers, including liver and intrahepatic bile duct cancers, acute and chronic lymphocytic leukemia, and mantle cell lymphoma. The findings come as use of the drift-prone herbicide has skyrocketed across millions of acres throughout much of the Midwest and South in the past three years due to the Environmental Protection Agency’s approval of dicamba on genetically engineered soybeans and cotton.
