Atrazine’s effectiveness, safety and important role in agriculture is well documented in both the U.S. and worldwide. Developed by Syngenta, atrazine has long been a mainstay of corn, sorghum and sugarcane farmers for its control of a broad range of yield-robbing weeds.

Each year atrazine supports up to 85,000 American jobs in agriculture and benefits farmers by more than $3 billion. Atrazine increases U.S. corn crop yields by about 7 bushels per acre, or more than 600 million bushels annually. Atrazine helps protect the environment and critical wildlife habitats by reducing soil erosion by up to 85 million tons each year. The proof is in the numbers; there is no substitute for atrazine.

Syngenta believes in atrazine, its effectiveness, its safety, its importance to agriculture - in the U.S. and worldwide.

Benefits Benefits
Atrazine has long been a mainstay of corn, sorghum and sugar cane farmers because it's effective in controlling a broad range of yield-robbing weeds, is safe to the crop and fits a variety of farming systems. Its ability to increase yields is critical as demand for food and alternative fuel increases.
Science & Safety Science & Safety
Atrazine passes the most stringent, up-to-date safety requirements in the world. In 2006, the U.S. Environmental Protection Agency (EPA) re-registered atrazine in 2006, based on the overwhelming evidence of safety from nearly 6,000 studies.
Drinking Water Drinking Water
Atrazine poses no threat to the safety of our drinking water supplies. In 2008, none of the 122 Community Water Systems monitored in 10 states exceeded the federal standards set for atrazine in drinking water or raw water.
Amphibians Amphibians
The latest, cutting-edge research shows that atrazine has no adverse effect on frogs. In reviewing the research in 2007, EPA went so far as to say, "the data are sufficiently robust to outweigh previous efforts to study the potential effects of atrazine on amphibian gonadal development" and "there is no compelling reason to pursue additional testing."
Stewardship Stewardship
Syngenta's stewardship of atrazine - from watershed management to farmer education - is unsurpassed in the industry.

Save the Frogs EPA Petition Atrazine and its potential impacts on amphibian sexual development underwent a detailed review and evaluation in 2003 by the EPA. At that time, EPA considered all relevant scientific publications and reports, and included several studies cited in the petition summary as scientific evidence
