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.
