Available in PDF, EPUB and Kindle. Book excerpt: Pararaquat (1,1'-dimethyl-4,4-bipyridlnium) and its dichioride salt (1,1'-dimethyl-4,4-bipyridinium dichloride) are broad-spectrum contact plant killers and herbage desiccants that were introduced commercially during the past 25 years. Today, they rank among the most widely used herbicides globally and are frequently used in combination with other herbicides. The recommended paraquat field application rates for terrestrial weed control usually range between 0.28 and 1.12 kg/ha (0.25 and 1.0 lb/acre), and for aquatic weed control the range is 0.1-2.0 mg/L. Target plant species are unable to metabollze paraquat and tend to contain elevated residues; paraquat-resistant strains of terrestrial flora, whose numbers are increasing, require greater concentrations for control and may contain proportionately greater residues. Paraquat from decayed flora is usually adsorbed to soils and sediments. Paraquat in surface soils generally photoecomposes in several weeks, but paraquat in subsurface soils and sediments may remain bound-and biologically unavailable-for many years without significant degradation.
