The European Commission, which already had restricted use of neonicotinoid insecticides, is considering restrictions on another insecticide to protect honeybees.
Members of the Standing Committee on the Food Chain and Animal Health backed the restrictions on fipronil, according to a news release.
In a vote, 23 member states supported the restrictions, with two member states voting against it and three abstanining.
The proposal would restrict the crops on which fipronil could be used as a seed treatment.
Treated seed could be used in greenhouses with special permission. The proposal would exempt field-sown leeks, shallots, onions, and brassicas.
Treatment of corn and sunflower seed would not be permitted.
Under the proposal, the commission would review the restrictions in two years.
