Agronomy professionals from around the world converged at the Crop Sciences Research and Education Center’s South First Street facility on August 26 for in-field presentations and opportunities to interact with ACES faculty.

The event is hosted biannually to coincide with the Farm Progress Show in Decatur. Most of the attendees hailed from Brazil and Argentina.

URBANA, Ill. – Corn, soybean, and cotton farmers shudder at the thought of Palmer amaranth invading their fields. The aggressive cousin of waterhemp – itself a formidable adversary – grows extremely rapidly, produces hundreds of thousands of seeds per plant, and is resistant to multiple classes of herbicides, including glyphosate.

URBANA, Ill. – Bacterial leaf streak, a foliar disease in corn, has only been in the United States for a handful of years, but Tiffany Jamann says it’s a major problem in the Western Corn Belt.

URBANA, Ill. – Nitrogen from agricultural production is a major cause of pollution in the Mississippi River Basin and contributes to large dead zones in the Gulf of Mexico.

Illinois and other Midwestern states have set goals to reduce nitrogen load through strategies that include different land management practices. A new study from University of Illinois researchers, published in Journal of Environmental Management, uses computer modeling to estimate how those practices may be affected by potential changes in the climate, such as increased rainfall.

URBANA, Ill. – Waterhemp and Palmer amaranth, two aggressive weeds that threaten the food supply in North America, are increasingly hard to kill with commercially available herbicides. A novel approach known as genetic control could one day reduce the need for these chemicals. Now, scientists are one step closer.

URBANA, Ill. – A corn gene identified from a 118-year-old experiment at the University of Illinois could boost yields of today’s elite hybrids with no added inputs. The gene, identified in a recent Plant Biotechnology Journal study, controls a critical piece of senescence, or seasonal die-back, in corn. When the gene is turned off, field-grown elite hybrids yielded 4.6 bushels more per acre on average than standard plants.

URBANA, Ill. – When a dead bat was found in a package of salad greens in 2017, the Florida story spurred product recalls and national media attention. The incident, assumed to be rare, was one of dozens of cases of consumers finding animals – live, dead, or severed – in fresh produce over the past 15 years. A University of Illinois study catalogues and analyzes these incidents as part of a larger effort towards greater food safety and quality improvements in the fresh produce industry.

CHAMPAIGN, Ill. – A new computer model incorporates how microscopic pores on leaves may open in response to light—an advance that could help scientists create virtual plants to predict how higher temperatures and rising levels of carbon dioxide will affect food crops, according to a study published in a special issue of the journal Photosynthesis Research today.

URBANA, Ill. – The public will have the opportunity to learn from more University of Illinois scientists than ever before during the 62^nd Agronomy Day on Aug. 22. Researchers and Extension specialists from across the College of Agricultural, Consumer and Environmental Sciences will share the latest discoveries and best practices in agronomy and land stewardship.

URBANA, Ill. – We’ve all heard about bacteria that are becoming resistant to multiple types of antibiotics. These are the so-called superbugs perplexing and panicking medical science. The plant analogue may just be waterhemp, a broadleaf weed common to corn and soybean fields across the Midwest. With resistance to multiple common herbicides, waterhemp is getting much harder to kill.
