Palmer amaranth grows very fast, germinates throughout the season, produces lots of seeds, can tolerate heat extremes and is very adaptable, researchers report.

An invasive weed that has put some southern cotton farmers out of business is now finding its way across the Midwest – and many corn and soybean growers don’t yet appreciate the threat, University of Illinois researchers report.

Teff, a nutritious grain, is a staple in Ethiopia. Its seeds are tiny – so small that some say its name was derived from the Amharic word for “lost.” Now, thanks to a creative educational initiative based at the University of Illinois, much less of the precious teff will be lost in Ethiopia.

Crops that produce more while using less water seem like a dream for a world with a burgeoning population and already strained food and water resources. This dream is coming closer to reality for University of Illinois at Urbana-Champaign researchers who have developed a new computer model that can help plant scientists breed better soybean crops.

A new technique to fight crop insect pests may affect different insect populations differently, researchers report. They analyzed RNA interference (RNAi), a method that uses genetic material to “silence” specific genes – in this case genes known to give insect pests an advantage. The researchers found that western corn rootworm beetles that are already resistant to crop rotation are in some cases also less vulnerable to RNAi.
