What is Glyphosate?

Glyphosate (tradenames include Roundup©, Touchdown©, Rodeo©, and others) is an organic solid of odorless white crystals. It is a non-selective herbicide used on many food and non-food crops as well as non-crop areas such as roadsides. When applied at lower rates, it serves as a plant growth regulator. The most common uses include control of broadleaf weeds and grasses in: hay/pasture, soybeans, field corn; ornamentals, lawns, turf, forest plantings, greenhouses, rights-of-way. Glyphosate is currently the world’s best selling herbicide, used in more than 90 countries and on more than 150 crops. Glyphosate use in agriculture has tripled since 1997, largely due to the increasing popularity of Roundup Ready® crops (including corn and soybeans), which have been genetically modified to tolerate glyphosate. The U.S. Environmental Protection Agency has set a drinking water Maximum Contaminant Level (MCL) of 700 micrograms per liter for glyphosate.
