Glyphosate vs. Paraquat

Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase.

Paraquat (trivial name; ), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is an organic compound with the chemical formula [(C6H7N)2]Cl2. It is classified as a viologen, a family of redox-active heterocycles of similar structure.

A white solid, C3H8NO5P, that is soluble in water, used as a broad-spectrum herbicide.

A toxic nonpersistent contact herbicide, C12H14 N2, usually formulated as its colorless dichloride salt, C12H14Cl2N2, or yellow bismethyl sulfate salt, C12H14N2O8S2.

N-phosphonomethyl glycine, the active ingredient of several herbicides that inhibit a plant growth enzyme.
