Clothianidin is an insecticide developed by Takeda Chemical Industries and Bayer AG. Similar to thiametoxam and imidacloprid, it is a neonicotinoid.
Criticism
Clothianidin is being studied regarding mass dieoffs of honeybees in some parts of Europe. Use of clothianidin was prohibited by the German Federal Office of Consumer Protection and Food Safety on May 15, 2008[1] until new studies can prove the innocuousness of the product.[2]
In August 2008, the Natural Resources Defense Council sued the United States Environmental Protection Agency after the latter agency failed to provide records related to studies regarding clothianidin's possible effects on bees.[3]
