  • Paraquat is the common herbicide name for 1,1 -dimethyl-4, 4 -bipyridinium dichloride.
  • Commercially available paraquat is produced and sold as the dichloride salt.
  • Paraquat is an extremely nonselective, water-soluble contact herbicide of the bipyridyl class.
  • Paraquat is the most highly acutely toxic herbicide to be marketed over the last 60 years.
  • Gramoxone, manufactured by Syngenta, is the most common trade name for paraquat, but the herbicide is also sold under many different
    names by many different manufacturers.
  • The first commercial paraquat formulation for agricultural use was produced by Imperial Chemical Industries, Ltd. in England and was registered there in 1962.
  • Paraquat is used as a herbicide, desiccant, defoliant, and plant growth regulator.
  • Paraquat is a fast-acting, non-selective contact herbicide that is absorbed by the foliage.
  • China is now the world’s largest manufacturer of paraquat, producing more than 100,000 tones per year.
  • According to industry sources, between 1995 and 2001 3.9% of total global sales were to oil palm plantations, 3.1% to banana plantation and 2.5% to tea estates – in all 9.5% of total sales to just 3 plantation crops mainly in developing countries.
  • China’s paraquat industry has developed rapidly in recent years, with technical output growing with CAGR of 21% in 2003~2008.
  • As the largest paraquat technical supplier in the world, China has created a new record in paraquat technical capacity in 2009, hitting 105,000t/a.
  • It is used preplant or preemergence on vegetables, grains, cotton, grasses, sugar cane, peanuts, potatoes, and tree plantation areas; postemergence
    around fruit crops, vegetables, trees, vines, grains, soybeans, and sugar cane; during the dormant season on clover and other legumes; as a
    desiccant or harvest aid on cotton, dry beans, soybeans, potatoes, sunflowers, and sugar cane; and as a post harvest desiccant on staked tomatoes.
  • Paraquat dichloride is also used on non-crop areas such as public airports, electric transformer stations and around commercial buildings to control weeds.
  • Paraquat dichloride is applied aerially, by groundboom, backpack sprayer, and low pressure handwand.
