The History of Glyphosate

Glyphosate has a 40-year history of use for effective weed management. Regulatory and scientific authorities worldwide, such as the Environmental Protection Agency and European Commission, have concluded that glyphosate, when used according to label directions, does not pose an unreasonable risk to human health, the environment, or pets. These regulatory authorities periodically review the safety of glyphosate as well.

History of Global Uses:

  • 1974 – Control of perennial and annual weeds in non-crop and industrial areas.
  • 1976 – Perennial weed control in perennial crops and before planting or following harvest of annual crops with first crop use label.
  • 1978 –Spot spraying of perennial weeds in annual crops like cotton and soybeans.
  • 1979 –Selective application in annual crops with re-circulating sprayers or rope wick applicators for control of annual and perennial weeds.
  • 1986 –Control of annual weeds prior to planting annual crops in reduced or no-tillage systems.
  • 1996 –Introduction of Roundup Ready® technology, which permitted direct application for weed control in glyphosate-tolerant crops.
