A trial began against Swiss agribusiness giant Syngenta over its decision to introduce a genetically engineered corn seed variety to the U.S. market before China approved it for imports.

 

It's the first of tens of thousands of cases to go to trial over the issue. The proceedings started Monday in Kansas City, Kansas. The federal trial involves thousands of plaintiffs from Kansas. That trial and another soon in Minnesota are meant to provide guidance for how the complex web of litigation in state and federal courts could be resolved.

 

The lawsuits allege Syngenta wrecked China as an increasingly important export market for U.S. corn and caused price drops that hurt all producers.

 

Syngenta denies it caused farmers any losses.
