Bayer has agreed to a proposed $7.25 billion deal to settle thousands of U.S. lawsuits that blame Roundup for causing cancer. Bayer and lawyers for cancer patients announced Tuesday that they were filing the proposed settlement in St. Louis. It comes as the U.S. Supreme Court is preparing to hear Bayer’s argument about federal rules and warning labels for the popular weedkiller. That separate case will continue. Bayer says Roundup's key ingredient of glyphosate does not cause non-Hodgkin’s lymphoma. But the company says legal costs have threatened Roundup sales in U.S. farming markets. Bayer bought Monsanto, the original Roundup maker, in 2018.
