When a sweet corn breeder reached out in 2021 to report severe injury from the herbicide tolpyralate, Marty Williams hoped it was a fluke isolated to a single inbred line. But two years later, after methodical field, greenhouse, and genetic testing, his new Pest Management Science study not only confirms sensitivity to tolpyralate in 49 sweet corn and field corn lines, but also reveals a new genetic vulnerability that may affect corn more generally.

After five trailblazing years, the Center for Digital Agriculture (CDA) at the University of Illinois Urbana-Champaign has a new executive director, John Reid, who plans to support CDA’s growth across all dimensions of use-inspired research, translation of research into practice, and education and workforce development. 

Nutrient runoff from agricultural production is a significant source of water pollution in the U.S., and climate change that produces extreme weather events is likely to exacerbate the problem. A new study from the University of Illinois Urbana-Champaign looks at how extreme rainfall impacts runoff and suggests possible mitigation strategies.

URBANA, Ill. —The College of Agricultural, Consumer and Environmental Sciences (ACES) at the University of Illinois Urbana-Champaign has been a leader in agricultural education since its founding, turning out scores of teachers who inspire the next generation. Now, an ACES alumnus has helped revitalize agricultural education in his local district with the development of an agriculture education building and program at Meridian High School in Macon, Illinois.

When farmers harvest their grain, they can choose to sell it right away or store it to obtain better prices later in the season. A new study from the University of Illinois Urbana-Champaign explores how Illinois corn and soybean producers make those decisions and why the cost-benefit evaluation of storage may differ across farms.

It has been a quarter century since corn and soybeans were engineered to withstand the withering mists of the herbicide glyphosate. Initially heralded as a “silver bullet” for weed control, the modified crops and their herbicide companion were quickly and widely adopted across corn and soybean-growing regions of North America. In the years that followed, though, weeds targeted for eradication quietly fomented a rebellion. 

A promising new form of ammonium phosphate fertilizer has been field-tested by University of Illinois Urbana-Champaign researchers. The fertilizer, struvite, offers a triple win for sustainability and crop production, as it recycles nutrients from wastewater streams, reduces leaching of phosphorus and nitrogen in agricultural soils, and maintains or improves soybean yield compared to conventional phosphorus fertilizers.

Waterhemp, the aggressive weed threatening Corn Belt crop production, is throwing curveballs once again, according to researchers at the University of Illinois Urbana-Champaign. The weed has famously developed resistance to not one or two, but seven herbicide sites-of-action classes, nearly exhausting the chemical tools farmers can use to defend their livelihood.

URBANA, Ill. — The Illinois Regenerative Agriculture Initiative (IRAI) marks the successful completion of its first three years with a new name: I-Regen. The name change reflects an ongoing commitment to the future of regenerative agriculture in the Midwest. I-Regen encourages diversified value chains that balance the health and wealth of Midwest agricultural systems, creating a resilient bioeconomy that combats climate change, enhances soil and water quality, supports communities, and ensures food security.

Over the past decades, Brazil has become the world’s leading soybean producer, as well as the leading consumer of pesticides. Despite concerns about potential public health consequences, little is known about the effects of pesticide exposure in the general population.
