Analysis of glyphosate and aminomethylphosphonic acid in water, plant materials and soil
Pest Management Science, 2015AbstractThere is a need for simple, fast, efficient and sensitive methods of analysis for glyphosate and its degradate aminomethylphosphonic acid (AMPA) in diverse matrices such as water, plant materials and soil to facilitate environmental research needed to address the continuing concerns related to increasing glyphosate use. A variety of water‐based

Dissipation of Glyphosate and Aminomethylphosphonic Acid in North American Forests
Journal of Agricultural and Food Chemistry, 1994Residues of glyphosate (N-phosphonomethylglycine) and its metabolite aminomethylphosphonic acid (AMPA) were followed on three forested sites in Oregon, Michigan, and Georgia. Eight-hectare residual stands of low-quality hardwoods were treated with 4.12 kg/ha glyphosate ae applied aerially in late summer.

Synthesis of C-heteryl-substituted aminomethylphosphonic acids derivatives
Russian Journal of General Chemistry, 2010The available diethyl 5-hydrazino-2-p-tolyl-1,3-oxazol-1-ylphosphonate was readily acylated with chlorides of carboxylic acids of heterocyclic series. On heating in acetic acid it underwent the oxazole ring cleavage, recyclization and diethylation that was used to prepar the substituted 2-p-toluylaminomethylphosphonic acids containing a series of 2 ...

Interactions of aminomethylphosphonic acid and sarcosine with montmorillonite interlayer surfaces
International Journal of Quantum Chemistry, 2007AbstractThe smectite clay, montmorillonite, can be found in many soils throughout the world. In addition to its importance in agriculture and soil remediation, montmorillonite has extensive applications in industry both in its natural form and as a component of composite materials.

Degradation of 14C-glyphosate and aminomethylphosphonic acid (AMPA) in three agricultural soils
Journal of Environmental Sciences, 2010Glyphosate (N-phosphonomethyl glycine) is the most used herbicide worldwide. The degradation of 14C-labeled glyphosate was studied under controlled laboratory conditions in three different agricultural soils: a silt clay loam, a clay loam and a sandy loam soil. The kinetic and intensity of glyphosate degradation varied considerably over time within the

Abstract Three small ponds in the boreal forest of southern Manitoba were treated with an aerial application of 2.1 kg/ha glyphosate. Two of the ponds had been treated the preceding year with 0.9 kg/ha glyphosate, whereas the third was previously untreated.
