The European Commission has proposed that member states restrict the use of certain classes of pesticide that are believed to be harmful to bees.
Sprays that use neonicotinoid chemicals should only be used on crops that are not attractive to the insects they said. The sale of seeds treated with these chemicals should also be prohibited.
Bayer, one of the companies who make the pesticides, says they are convinced they can be used without harm to bees.
Earlier this month, the European Food Safety Authority (Efsa) issued guidance on the use of neonicotinoids, in which they recognised “high acute risks” to bees who encountered residue from these sprays in pollen and nectar in crops like oilseed rape and sunflowers.
