BRUSSELS (Reuters) - The European Commission decided on Monday not to renew approval for a pesticide linked to harming bees, effectively banning Bayer’s insecticide known as thiacloprid.

The decision follows approval by a majority of EU governments in October last year, based on a proposal from the Commission, the bloc’s executive.

“There are environmental concerns related to the use of this pesticide, particularly its impact on groundwater, but also related to human health, in reproductive toxicity,” Health Commissioner Stella Kyriakides said in a statement.

In principle, farmers will not be allowed to use the insecticide, sold under brands Calypso and Biscaya, after April 30 this year, when its current approval expires.

In practice, EU governments have until Aug. 3 this year to withdraw authorisations, with a possible grace period ending on Feb. 3, 2021.
