Neonicotinoid Insecticide Ban May End Rapeseed Crops in the EU The EU restricted the use of three neonicotinoid insecticides on flowering plants beginning in 2013 because of a belief they were responsible for the decline in bee populations. It then banned the use of all such insecticides on all fields for the same reason despite no scientific consensus that they are causing the problem.
