PARIS (Reuters) - France will not accept a five-year extension to the license for weed-killer glyphosate as proposed by the European Commission on Friday, said an official in the French Prime Minister’s office.

France was continuing to seek an extension “for a period that would not go beyond four years,” added the official.

The Commision had proposed a five-year period after failing to secure enough backing for a 10-year license renewal for glyphosate, a common weed-killer that has divided European Union countries over its potential effects on health.
