Subpages: Herbicides | Glyphosate in Agriculture & Horticulture

“A pesticide is any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any pest. Though often misunderstood to refer only to insecticides, the term pesticide also applies to herbicides, fungicides, and various other substances used to control pests. Pesticides also include plant regulators, defoliants and desiccants.” (US EPA)

New Study Shows Roundup Kills Bees
BY AUSTIN PRICE for sierreaclub.org | OCT 3 2018. The article cites this scientific publication: Glyphosate perturbs the gut microbiota of honey bees, Erick V. S. Motta et al., 2018 PNAS 115 (41) 10305-10310. From Significance of the PNAS paper: “Increased mortality of honey bee colonies has been attributed to several factors but is not fully understood. The herbicide glyphosate is expected to be innocuous to animals, including bees, because it targets an enzyme only found in plants and microorganisms. However, bees rely on a specialized gut microbiota that benefits growth and provides defense against pathogens. Most bee gut bacteria contain the enzyme targeted by glyphosate, but vary in whether they possess susceptible versions and, correspondingly, in tolerance to glyphosate. Exposing bees to glyphosate alters the bee gut community and increases susceptibility to infection by opportunistic pathogens. Understanding how glyphosate impacts bee gut symbionts and bee health will help elucidate a possible role of this chemical in colony decline.”
