SAN FRANCISCO (AP) — Agribusiness giant Monsanto on Tuesday appealed a $78 million verdict in favor of a dying California man who said the company’s widely used Roundup weed killer was a major factor in his cancer. The company filed a notice of appeal in San Francisco Superior Court challenging a jury verdict in favor of DeWayne Johnson. In August, the jury unanimously found that Roundup caused Johnson’s non-Hodgkin’s lymphoma and awarded him $289 million.
