Leaked Memo Shows EPA Doubts About Bee-Killing Pesticide

Over the concerns of its own scientists, the Environmental Protection Agency continues to approve a controversial pesticide introduced to U.S. markets shortly before the honeybee collapse, according to documents leaked to a Colorado beekeeper.
The pesticide, called clothianidin, is manufactured by German agrochemical company Bayer, though it’s actually banned in Germany. It’s also banned in France, Italy and Slovenia. Those countries fear that clothianidin, which is designed to be absorbed by plant tissue and released in pollen and nectar to kill pests, is also dangerous to pollen- and nectar-eating bees that are critical to some plants’ reproductive success.
In 2003, the EPA approved clothianidin for use in the United States. Since then, it’s become widely used, with farmers purchasing $262 million worth of clothianidin last year. It’s used on used on sugar beets, canola, soy, sunflowers, wheat and corn, the last a pollen-rich crop planted more widely than any other in the United States, and a dietary favorite of honeybees.
During this time, after several decades of gradual decline, honeybee colonies in the United States underwent widespread, massive collapses...

In 2009, Italy's neonicotinoid-free corn sowing resulted in no cases of widespread bee mortality in apiaries around the crops. This had not happened since 1999. The European Research Center, Youris, reported that Moreno Greatti, from the University of Udine stated, "Bee hives have not suffered depopulation and mortality coinciding with maize sowing this year. Beekeepers from Northern Italy and all over the country are unanimous in recognizing that the suspension of neonicotinoid- and fipronil-coated maize seeds."
