Paraquat is the trade name for N, N -dimethyl-4, 4 -bipyridinium dichloride, one of the most widely used herbicides in the world. Paraquat, a viologen, is quick-acting and non-selective, killing green plant tissue on contact. It is redistributed within the plant but does not harm mature bark. Paraquat can protect crops by controlling a wide range of annual and certain perennial weeds that reduce crop yield and quality by competing with the crop for water, nutrients, and light. Pure paraquat is highly toxic to mammals and humans if ingested, potentially leading to acute respiratory distress syndrome (ARDS). There are no specific antidotes. A large majority (93%) of fatalities from paraquat poisoning are cases of intentional self-administration, ie, suicides. [National Center for Biotechnology Information.
