Research by Syngenta and Bayer on their own neonicotinoid pesticides revealed that the products caused significant damage to honeybees, according to Greenpeace. The environmental campaigning group has obtained the unpublished field trials through a freedom of information request. Previous research had shown that the levels of the chemicals in fields damaged bees; these studies prove that they also damage the performance of colonies. Bees and other pollinators are essential for pollinating 75% of global food crops. Neonicotinoids, the most commonly used insecticides in the world, were banned in relation to flowering crops by the EU in 2013.
