The commissioners were due to make a decision this afternoon (27 June) on whether to extend the popular weedkiller's license before it expires on 30 June.
But last Thursday's vote by the UK public in favour of leaving the EU has bumped glyphosate down the agenda.
With tomorrow's European Council meeting set to revolve around Brexit, commission spokesperson Enrico Brivio said that the agenda of today's commission meeting had to change and no discussion or decision on glyphosate would be taken.
Meanwhile a meeting of the Plants Animals Food and Feed (PAFF) Committee this morning discussed plans to ban POE-tallowamine, which is often used as a coformulant with glyphosate but has been linked with health issues. It also discussed the recommendations to minimise glyphosate use in public areas and as a pre-harvest application. None of the issues were taken to a vote.
Horticulture Week understands that it is possible that the College of Commissioners will use written procedure - rather than oral procedure - to make its decision, meaning it could reach a decision without meeting in person. The commission is likely to agree to the temporary extension of the weedkiller's license by 30 June, as a majority of member states are in favour of authorization.
The extension would allow the weedkiller to remain authorized until the European Union's Agency for Chemical Products publishes its opinion on the matter, before 31 December 2017.
Whether or not to renew glyphosate's license has been heavily debated since the publication in 2015 of a study from a World Health Organisation agency saying glyphosate probably causes cancer in humans. Other regulatory organisations say glyphosate is not a cancer risk, but the public and NGOs are increasingly in favour of a ban.
