'''Glyphosate''' [N-(phosphonomethyl)glycine] is a broad-spectrum systemic herbicide. It is classified as a non-selective herbicide, since it kills most plants, both broad-leaf and grass.<ref>http://npic.orst.edu/factsheets/glyphogen.html</ref> It is absorbed mainly through foliage, though also slightly through roots. It works as an enzyme inhibitor, preventing plants from synthesizing three amino acids, tyrosine, phenylalanine, and tryptophan. | '''Glyphosate''' [N-(phosphonomethyl)glycine] is a broad-spectrum systemic herbicide.
