Exploratory study of the behavior of glyphosate and AMPA in three profiles of a Haplustol Entish soil province of Córdoba, Argentina

Abstract

Glyphosate is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf weeds and grasses known to compete with commercial crops. The most common formulation of Glyphosate is as isopropylamine salt, which is commercialized as Roundoup-N®. Its main metabolite is aminomethylphosphonic acid (AMPA), which is recognized by some authors as slightly toxic. There is evidence of resistance of some species of herbs that adapt after prolonged use of glyphosate
