Monsanto Co. has asked a San Francisco Superior Court judge to toss a $289 million verdict, insisting the plaintiff’s evidence failed to show that its herbicide Roundup caused non-Hodgkin lymphoma.

The Aug. 10 verdict came the first trial alleging a link between Monsanto’s Roundup to cancer. The jury awarded $39.2 million in compensatory damages and $250 million in punitive damages to Dewayne “Lee” Johnson, diagnosed in 2014 with terminal non-Hodgkin lymphoma after using a similar Monsanto herbicide, Ranger Pro, as part of his job as a school groundskeeper.
