Glyphosate and glufosinate are herbicides used for weed and vegetation control. AMPA, aminomethylphosphonic acid, is a degradation product of glyphosate. Since the introduction of glyphosate resistant (round-up ready) corn and soybeans glyphosate has become the most widely used herbicide in the world.
