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.
