The 2025 Glyphosate Report Card: Some Good, Some Bad

As the calendar gets ready to turn to June, schoolchildren across the country are anticipating what their final report cards will look like. In this spirit, let’s consider how the 2024-25 report card looks for glyphosate. Overall, it’s been a mix of positive and negative grades for one of agriculture’s most popular herbicides.

First, let’s look at some of the failing grades. For years now, glyphosate (and primary supplier Bayer) have been the subject of thousands of lawsuits from individuals claiming repeated use of the herbicide caused them health problems. This has resulted in billions of dollars in damage awards from juries. In fact, things have gotten some bad that Bayer has hinted that it would stop producing its Roundup brand glyphosate “in the near future.”

Grade this an F (for financial burden).

More recently, the Make America Heathy Again (MAHA) Commission is preparing to release a report that insiders say could blame “U.S. farmers [for] harming Americans through their production practices.” This likely would point the finger at crop protection products such as glyphosate. In anticipate of this report, several ag trade groups such as the American Soybean Association, National Association of Wheat Growers, and the National Corn Growers Association have released statements criticizing the MAHA report.

Grade this an I (for incomplete information).

But there are some passing grades as well. Over the past two months, two states – North Dakota and Georgia – have passed legislation affirming that federal warning labels on crop protection products such as glyphosate are “ample warning of health risks and supersede the need for additional state and/or local warning labels.” This will remove one of the key arguments used by plaintiffs in glyphosate damage lawsuits across the country. Other states such as Missouri, Iowa, and Tennessee are also considering similar legislative protections for crop protection products.

Grade this an A (for about time).

Finally, Bayer has petitioned the U.S. Supreme Court to officially weigh in on the question of federal vs. state/local warning labels. This potentially could open the door for a national precedent being set regarding current and future warning label issues.

Grade this a B (for better late than never).

What do you think will have the greatest impact on glyphosate's future?

Re: Imagine Life Without Glyphosate

https://www.lancasterfarming.com/farming-news/news/letters-to-the-editor-march-22-2025/collection_442feb91-b377-46bd-83dc-a24f2657a7fd.html

Listening to the radio while driving around the beltway of Washington, D.C., I hear a commercial repeated several times about glyphosate.

It purports that glyphosate is a kind of “essential tool” for our farmers. As I got to thinking about it, I decided I wanted to bring that issue into the classroom at Rutgers, the State University of New Jersey where I am teaching a seminar course for graduate students.

Next, I recall reading the book “Toxic Legacy: How the Weedkiller Glyphosate Is Destroying Our Health and the Environment” by Stephanie Seneff.

So, I get the idea to invite Dr. Seneff, who is on the faculty at Massachusetts Institute of Technology, to be a seminar speaker. Dr. Seneff agrees to present the seminar along the lines of her book title, so long as it can be done remote via Zoom from Hawaii.

All goes well with the seminar delivery from Hawaii to New Jersey. A grad student attending asks the speaker a good question: How she would go about growing corn and soybean without using glyphosate? The seminar speaker seemed hesitant to provide a satisfactory response.

As a soil scientist, I also pondered the question and formulated my own answer that I would later share with students.

Meanwhile, I emailed that question to Dr. Don Huber, professor emeritus of plant pathology at Purdue University in Indiana.

Dr. Huber, now living in Idaho, recently celebrated his 90th birthday and remains active as agricultural consultant. Dr. Seneff credits Dr. Huber as the scientist who inspired her to investigate the health and environmental issues surrounding the widespread use of the herbicide glyphosate.

With quick wit, Dr. Huber provided this reply to the growing of corn and soybean without glyphosate:

“My response is, we would grow them even better without the tied-up minerals and GMO drag. How do they think we grew corn before glyphosate?

“By getting rid of just some of the residual glyphosate in the soil, we had a 11-15 bushel/acre yield increase in corn last year without using glyphosate. Crop rotation, a little tillage, etc. work wonders, especially on glyphosate resistant weeds.

“Bill Johnson, weed scientist at Purdue, said it costs $50/acre more to control Roundup resistant weeds than it used to before Roundup.

“I’m happier when I’m healthy also, and RU is a major contributor to chronic illness. Just look at the 177,000 lawsuits just for NHL (Non-Hodgkin’s Lymphoma).

“Safe and nutritious food needs entering into the formula also. Shooting from the hip with my fingers.”

The answer provided by Dr. Huber is insightful and interesting. I believe it ought to be shared with a larger audience.

So, it is with this letter that I extend this national conversation about glyphosate with the readers of Lancaster Farming.
