New genetic vulnerability to herbicide found in nearly 50 sweet and field corn lines

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.

The silver bullet that wasn't: Glyphosate's declining weed control over 25 years

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.

Recycled phosphorus fertilizer reduces nutrient leaching, maintains yield

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.

New study indicates C4 crops less sensitive to ozone pollution than C3 crops

Ozone (O3) in the troposphere negatively impacts crop growth and development, causing significant decreases in crop yield worldwide. This airborne pollutant does not come directly from smokestacks or vehicles, but instead is formed when other pollutants, mainly nitrogen oxides and volatile organic compounds, react in the presence of sunlight. In an increasingly polluted atmosphere, understanding what plants are tolerant of O3 is critical to improving crop productivity and resilience.

Single gene controls Corn Belt weed's resistance to soil-applied herbicide

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.
