Illinois corn and soybean farmers could experience significant economic losses if glyphosate is banned, according to a recent study conducted by the University of Illinois Urbana-Champaign and the Illinois Soybean Association.
The research estimates annual losses ranging from $300 million to $609 million. Those figures represent a potential decline of 1.8% to 3.6% in farm revenue across the state’s major crop sectors.
Glyphosate remains one of the most commonly used weed-management tools for row crop production. To measure the potential effects of a ban, researchers analyzed herbicide usage patterns, production expenses, crop performance data, and available alternatives.
“I don't know of any farmer who wants to take a revenue loss by any stretch of the imagination, and especially when we've got such tight margins right now,” said study co-author Aaron Hager, professor and faculty Extension specialist in the Department of Crop Sciences, part of the College of Agricultural, Consumer and Environmental Sciences at Illinois. “Profits have been projected to be negative again this year for a lot of Illinois farmers, many of which may be on the verge of not being able to survive.”
Their analysis found that substitute weed-control products would likely cost more and may not provide the same level of effectiveness as glyphosate. As a result, farmers could face lower crop yields and increased operating expenses.
Researchers emphasized that the financial burden would come at a time when many farms are already dealing with narrow margins and volatile market conditions. Additional expenses could further challenge farm profitability.
“We actually discussed studying several different chemicals initially and landed on glyphosate,” said study co-author Corey Lacey, environmental policy manager at the Illinois Soybean Association. “We chose it because a glyphosate ban would probably have the biggest impact on farmers since it is one of the most used crop protection tools by corn and soybean farmers in Illinois. So a glyphosate ban is something that we really have to talk about and put some real numbers to.”
The study also examined the role of glyphosate in conservation tillage systems. These systems help reduce soil disturbance, conserve moisture, and lower fuel consumption. Without glyphosate, some growers may be forced to rely more heavily on conventional tillage practices, increasing equipment use and fuel costs.
While the report focused on economic outcomes, the researchers acknowledged that a complete assessment would also need to consider environmental, public health, tax revenue, and supply chain impacts. Those factors were outside the scope of the current analysis.
Industry leaders say the findings provide valuable information for policymakers considering future pesticide regulations. The researchers also noted that the same evaluation framework could be used to assess potential restrictions on other agricultural chemicals in the future.
