The B.C. Supreme Court has certified a class-action lawsuit against global agriculture firm Syngenta over claims that its herbicide products cause Parkinson’s disease.

A decision released online this week says the case was filed in B.C. in August 2022, alleging the Switzerland-based firm’s family of herbicide products, marketed as Gramoxone, causes Parkinson’s disease.
