“Organic Fertilizer Is Great at Killing Bees,” by Ruth Kava.
A given of the organic agriculture movement is that organic growers don’t use synthetic pesticides and fertilizers, like organophosphates and glyphosate (RoundUp). All that fear-mongering about pesticides is only possible because environmental groups only test for the synthetic kind, they don’t test for the pesticides and fertilizers used by organic growers. Because those are safer? Absolutely not. In the Journal of Economic Entomology, Brazilian scientists studied the effects of copper sulfate, a fertilizer and pesticide that is approved in the U.S. for use in organic agriculture and applied to the leaves of crop plants. Obviously the smarter approach is to treat seeds instead of using a broad spectrum pesticide, and that is the premise behind neonicotinoids, which environmental groups also protest — by treating seeds, which bees have no interest in, rather than plants, which bees do have an interest in, farmers get better yields with less environmental impact.
