Determination of Glyphosate in Dried Wheat by <sup>1</sup>H-NMR Spectroscopy
A wheat field was sprayed with a dosage of 1.1 kg a.i./ha Roundup PowerMax 10 days before harvest. The <sup>1</sup>H Nuclear Magnetic Resonance (NMR) spectroscopy was used for the detection and quantification of the glyphosate (GLYP) in dried wheat spikelets, leaves, and stems. The quant...
