It’s not just the State and Defense departments that are reeling this month from leaked documents. The Environmental Protection Agency now has some explaining to do, too. In place of dodgy dealings with foreign leaders, this case involves the German agrichemical giant Bayer; a pesticide with an unpronounceable name, clothianidin; and an insect species crucial to food production (as well as a food producer itself), the honeybee….
…An internal EPA memo released Wednesday confirms that the very agency charged with protecting the environment is ignoring the warnings of its own scientists about clothianidin, a pesticide from which Bayer racked up €183 million (about $262 million) in sales in 2009.
Clothianidin has been widely used on corn, the largest U.S. crop, since 2003. Suppliers sell seeds pre-treated with it. Like other members of the neonicotinoid family of pesticides, clothianidin gets “taken up by a plant’s vascular system and expressed through pollen and nectar,” according to Pesticide Action Network of North America (PANNA), which leaked the document along with Beyond Pesticides. That effect makes it highly toxic to a crop’s pests — and also harmful to pollen-hoarding honeybees, which have experienced mysterious annual massive die-offs (known as “colony collapse disorder”) here in the United States at least since 2006.
