Banning the agricultural herbicide atrazine  would cost between 21,000 and 48,000 jobs from corn  production losses alone, according to University of Chicago Economist Don Coursey, who announced his findings at a briefing sponsored by the Triazine Network at the National Press Club in Washington. The National Corn Growers Association  (NCGA) is part of the Triazine Network.
Coursey estimates atrazine’s annual production value to corn alone to be between $2.3 billion and $5 billion. Atrazine’s additional value to sorghum, sugar cane and other uses increases these totals.
“The economic data on atrazine are very clear,” Coursey says. “As a first-order estimate, banning atrazine will erase between 21,000 and 48,000 jobs related to or dependant on corn production, with additional job losses coming from both sugar cane and sorghum production losses. The range is wide because we have never before banned a product on which so many depend and for which suitable replacements have a wide variety of prices and application regimes.
“If all of that job loss were concentrated in the agricultural sector, its unemployment would grow by as much as 2.6%,” he adds. “Replacement costs for corn farmers could reach as high as $58/acre.”
Atrazine has been a mainstay of corn, sorghum and sugar cane production for 50 years. The second most-used herbicide  in the U.S., it controls a broad range of yield-robbing weeds, is safe for the crop and supports a variety of farming systems, including soil-saving conservation-till  agriculture.
“As a corn grower, I understand the importance of atrazine to crop production,” says NCGA President Darrin Ihnen. “At NCGA, we also understand that the safety of this important input has been proven time and time again through some of the most extensive testing ever completed on a single chemical. While we are confident that atrazine will once again be re-registered due to its safety, we are disappointed the regulatory practices could be swayed by political considerations rather than proven data.”
The U.S. Environmental Protection Agency  (EPA) re-registered atrazine in 2006 based on the evidence of nearly 6,000 studies and more than 80,000 public comments. It began an additional, unscheduled review of atrazine in late 2009.
“Atrazine is essential to U.S. agriculture,” says Jere White, Triazine Network chairman and executive director of the Kansas Corn Growers Association . “We appreciate Dr. Coursey’s findings and will distribute them to our members, the EPA and to our elected representatives. With unemployment still painfully high across the nation, we can’t afford to lose as many as 50,000 jobs and the corn yield that sustains them.”
EPA cited a media report and claims by a longtime anti-atrazine group when it announced the additional, unscheduled review. It was the first time in history EPA did not cite sound science to initiate a review process.
The Triazine Network was established in 1995 in response to U.S. EPA’s November 1994 decision to initiate a special review of the triazine herbicides, including atrazine, simazine and cyanazine. Since its inception, Triazine Network members have advocated use of sound science and established scientific methods to evaluate the health and environmental impacts of the triazine herbicides.
