Concerns remain chemical widely used in agriculture as a herbicide can kill all plants, algae, bacteria and fungi in a crop’s vicinity, affecting biodiversity.

Two-thirds of Europeans support a ban on glyphosate, the most-widely used agricultural chemical in the world’s history, according to a new Yougov poll.

A prohibition on the herbicide ingredient was backed by three quarters of Italians, 70% of Germans, 60% of French and 56% of Britons, in a survey of more than 7,000 people across the EU’s five biggest states.

Up to 150 MEPs in Strasbourg are expected to give urine samples today and tomorrow to see if they contain residues of the ingredient, ahead of a symbolic vote on prohibition this Wednesday.
