Changes in soil pH and addition of inorganic phosphate affect glyphosate adsorption in agricultural soil
(Wiley, 2022-02)Glyphosate is the most widely used herbicide in Argentina. The strong sorption of glyphosate to the mineral fraction of the soil can be affected by environmental conditions and agricultural management, such as the application ... -
Depth distribution of soil, glyphosate, and aminomethylphosphonic acid (AMPA) properties and analysis of crop yield in six long-term experiments

(2015)El objetivo fue evaluar el efecto tóxico de Clorpirifos, Cipermetrina y Glifosato sobre Milax gagates y Armadillidium vulgare. La unidad experimental fue un recipiente (36, 5 x 24,5 cm) con 10 cm de suelo, 45 g de residuo ... -
Efectos individuales y en mezclas de glifosato y clorpirifos sobre organismos indicadores en un ecosistema a pequeña escala = Effects of glyphosate and chlorpyrifos applied alone and in combination on indicator organisms in a small-scale ecosystem
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, Argentina., 2022-06-15)Se evaluó el efecto individual y en mezclas de glifosato y clorpirifos sobre Octolasion cyaneum, Porcellio scaber y Brassica napus. La unidad experimental consistió en un cilindro de PVC con 3 kg de suelo y se introdujeron ... -
Environmental fate of glyphosate and aminomethylphosphonic acid in surface waters and soil of agricultural basins
(Elsevier, 2013-11)Argentinian agricultural production is fundamentally based on a technological package that combines no-till and glyphosate in the cultivation of transgenic crops. Transgenic crops (soybean, maize and cotton) occupy 23 ... -
Epilithic biofilms as a discriminating matrix for long-term and growing season pesticide contamination in the aquatic environment: Emphasis on glyphosate and metabolite AMPA
(Elsevier, 2023-11)The indiscriminate use of pesticides represents high ecological risk in aquatic systems. Recently, the inclusion of epilithic biofilms as a reactive matrix has shown potential in diagnosing the health of water resources. ... -
First evidence of glyphosate and aminomethylphosphonic acid (AMPA) in the respirable dust (PM10) emitted from unpaved rural roads of Argentina
(Elsevier, 2021-02-04)The aim of this work was to compare the concentration of glyphosate and AMPA in the PM10 and the actual PM10 emission from agricultural soils and unpaved roads, located inside and outside farm fields. To determine the ... -
Glyphosate and aminomethylphosphonic acid (AMPA) are commonly found in urban streams and wetlands of Melbourne, Australia
(Elsevier, 2020-01)Glyphosate is the most widely-used pesticide for weed control in agriculture and in urban and residential areas. This is the first study to quantify glyphosate and AMPA levels in surface water in Australia from different ... -
Glyphosate and AMPA concentrations in the respirable dust emitted experimentally by soil aggregates, shortly after herbicide application
(Elsevier, 2020-06-15)The objective of this study was to analyze glyphosate- and aminomethylphosphonic acid (AMPA) concentrations in the respirable dust (RD) emitted by different soil aggregates, shortly after herbicide application in a field ... -
Glyphosate and AMPA concentrations in wind‐blown material under field conditions
(Wiley Online Library, 2018-03-01)Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased ... -
Glyphosate Biodegradation Potential in Soil Based on Glycine Oxidase Gene (thiO) from Bradyrhizobium
