Beekeepers have been concerned that pesticides are to blame for the bee die-offs devastating their industry for a while now. As we reported recently, their losses have spiraled out of control, putting not just the beekeepers but our entire agricultural system in peril.

The concern centers around a class of pesticides called neonicotinoids, which the Environmental Protection Agency (EPA) allowed to be marketed and sold even after the agency’s own scientists’ put up red flags. And now some in the industry have decided it’s time to formally challenge EPA’s negligence. On March 21, 27 beekeepers and four environmental groups filed a petition [PDF] with the agency asking it to take clothianidin — the neonicotinoid causing the most trouble — off the market until a long-overdue, scientifically sound review is completed.
