Common crop pesticides kill honeybee larvae in the hive

Four pesticides commonly used on crops to kill insects and fungi also kill honeybee larvae within their hives, according to new research. Scientists also found that N-methyl-2-pyrrolidone – an inert, or inactive, chemical commonly used as a pesticide additive – is highly toxic to honeybee larvae.

Toxic fungicide drifts beyond farms where it was applied.

from the StarTribune:

“Many Minnesotans are regularly exposed to [it] in the air they breathe,” said Emily Marquez, a scientist at PAN. “Even at low levels, airborne pesticides can raise serious health concerns.”

The Environmental Protection Agency (EPA) shares the Smiths’ concerns. It considers the fungicide – chlorothalonil – a likely carcinogen, based on animal testing, and an irritant to the skin, eyes and respiratory system. And it is extremely toxic to many forms of aquatic life.
