DOI: 10.1002/em.22534
Abstract: Glyphosate, the most heavily used herbicide world‐wide, is applied to plants in complex formulations that promote absorption. The National Toxicology Program reported in 1992 that glyphosate, administered to rats and mice at doses up to… read more here.

DOI: 10.1002/etc.3820
Abstract: Glyphosate is currently the most widely used herbicide in agricultural production. It generally enters aquatic ecosystems through surface water runoff and aerial drift. We evaluated the effect of glyphosate acid on biochemical parameters of periphyton… read more here.

DOI: 10.1002/etc.3851
Abstract: In Argentina, glyphosate use has increased exponentially in recent years as a result of the widespread adoption of no-till management combined with genetically modified glyphosate-resistant crops. This massive use of glyphosate has created concern about… read more here.

DOI: 10.1002/etc.5442
Abstract: Herbicides are the most widely used pesticides globally. Although used to control weeds, they may also pose a risk to bee health. A key knowledge gap is how bees could be exposed to herbicides in… read more here.

DOI: 10.1002/jeq2.20437
Abstract: Residual concentrations of glyphosate and its main transformation product aminomethylphosphonic acid (AMPA) are often observed in soils. The factors controlling their biodegradation are currently not well understood. We analyzed sorption-limited biodegradation of glyphosate and AMPA… read more here.

DOI: 10.1002/ps.4573
Abstract: BACKGROUND Five glyphosate-resistant populations of Chloris truncata originally collected from New South Wales were compared with one susceptible (S) population from South Australia to confirm glyphosate resistance and elucidate possible mechanisms of resistance. RESULTS Based… read more here.
