Superoxide generating substances

Paraquat (trivial name; ), or '''N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen''', is a toxic organic compound with the chemical formula [(C6H7N)2]Cl2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. It is one of the most widely used herbicides worldwide. It is quick-acting and non-selective, killing green plant tissue on contact.
