Abstract
Glyphosate is the most widely used herbicide on genetically modified Roundup Ready (RR)soybeans, which are resistant to the herbicide. These applications may lead to the presence ofglyphosate residues and its metabolite aminomethylphosphonic acid (AMPA) in RR soybeangrains treated with the herbicide. Therefore, studies on the traceability of glyphosate and AMPAresidues in RR soybean grain…
