The Environmental Protection Agency is pulling from the market a dozen products containing pesticides known to be toxic to a linchpin of the U.S. food system - the honeybee. The agency announced Monday it has canceled the registrations of 12 pest-killing products with compounds belonging to a class of chemicals known as neonicotinoids, as part of a legal settlement. For years, beekeepers and wildlife conversationalists alike have voiced concern that the widespread use of neonics, as the chemicals are commonly called, is imperiling wild and domesticated bees crucial to pollinating commercial fruit, nut and vegetable crops. The decision follows five years of litigation in which the beekeepers and environmentalists pressed the agency to mount a response to the use of neonics as regulators in Europe and Canada have taken steps toward banning the chemicals. Finally, at the end of 2018, three agribusinesses - Bayer, Syngenta and Valent - agreed to let the EPA pull from shelves the 12 pesticide products used by growers ranging from large-scale agricultural businesses to home gardeners. The legal settlement also compels the EPA to analyze the impacts of the entire neonic class on endangered species. Rebecca Riley, legal director of the nature program at the Natural Resources Defense Council, said that the agency has failed often in the past to adequately consider the potential impact of its pesticide approvals on endangered animals - something every federal agency is supposed to do.
