Monsanto, U.S. farm groups sue California over glyphosate warnings

Reuters – Monsanto Co and U.S. farm groups sued California on Wednesday to stop the state from requiring cancer warnings on products containing the widely used weed killer glyphosate, which the company sells to farmers to apply to its genetically engineered crops.

The government of the most populous U.S. state added glyphosate, the main ingredient in Monsanto’s herbicide Roundup, to its list of cancer-causing chemicals in July and will require that products containing glyphosate carry warnings by July 2018.

California acted after the World Health Organization’s International Agency for Research on Cancer (IARC) concluded in 2015 that glyphosate was “probably carcinogenic”.
