Pollinator habitat program spreads bad seeds with the good Dec 7, 2016 8:30 am8309 views Weed scientists in at least two Midwestern states have been reporting for years that a conservation program meant to provide habitat for pollinating insects is sowing bad seeds – including seeds of the potentially devastating agricultural weed Palmer amaranth – along with the good. Now, researchers at the University of Illinois have traced the weed seeds to at least one source: pollinator habitat seed sold by a company in the Midwest. Many Midwestern retailers sell mislabeled invasive vines Jan 8, 2018 9:00 am7714 views Gardeners hoping to celebrate the beauty of American bittersweet – a native vine that produces orange berries in the fall and is used for wreaths – may be unwittingly buying an invasive bittersweet instead. That’s because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online. Supersweet Sweet Corn: 50 Years in the Making Aug 7, 2003 9:00 am7163 views Fifty years ago, sweet corn wasn't all that sweet and had a short shelf-life, which made it difficult for grocery stores to stock it. As a result of the persistence of some UI corn researchers, today's sweet corn not only lives up to its name in taste, it maintains its high quality for more than a week, long enough to get it into stores and onto dinner tables. Jerald "Snook" Pataky, UI plant pathologist in the College of Agricultural, Consumer and Environmental Sciences, has researched the history of UI’s contribution to the existence of today's supersweet corn and will be one of the featured speakers at Agronomy Day on Aug. 21. s Eight Illinois researchers rank among world’s most influential Nov 18, 2016 9:15 am6823 views Eight University of Illinois researchers have been named to the Thomson Reuters / Clarivate Analytics Highly Cited Researchers list for 2016.

Corn better used as food than biofuel, study finds Jun 20, 2017 9:00 am6069 views Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs. Cahokia's rise parallels onset of corn agriculture May 14, 2020 8:15 am5966 views Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion. North American checklist identifies the fungus among us Nov 28, 2018 8:15 am5923 views Some fungi are smelly and coated in mucus. Others have gills that glow in the dark. Some are delicious; others, poisonous. Some spur euphoria when ingested. Some produce antibiotics. All of these fungi - and hundreds of thousands, if not millions, more - occur in North America. Of those that are known to science, 44,488 appear in a new checklist of North American fungi, published this month in the journal Mycologia. Report: Milkweed losses may not fully explain monarch butterfly declines Mar 13, 2017 4:15 pm5758 views Monarch butterfly declines cannot be attributed merely to declines in milkweed abundance, researchers report. Chill-tolerant hybrid sugarcane also grows at lower temperatures, team finds Jul 28, 2015 8:00 am5217 views U.S. farmers have long hoped to extend sugarcane’s growing range northward from the Gulf coast, substantially increasing the land available for sugar and biofuels. Several hybrid canes developed in the 1980s have proved hardy in cooler climes, surviving overwinter as far north as Booneville, Arkansas. But until now, no one had tested whether these “miscanes,” as they are called, actually photosynthesize, and thus continue to grow, when the thermometer dips. Agricultural fungicide attracts honey bees, study finds Jan 8, 2018 9:30 am4844 views When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports. Genomic study reveals evolutionary secrets of banyan tree Oct 8, 2020 9:15 am4766 views The banyan fig tree Ficus microcarpa is famous for its aerial roots, which sprout from branches and eventually reach the soil. The tree also has a unique relationship with a wasp that has coevolved with it and is the only insect that can pollinate it. In a new study, researchers identify regions in the banyan fig’s genome that promote the development of its unusual aerial roots and enhance its ability to signal its wasp pollinator. Ag robot speeds data collection, analyses of crops as they grow Mar 12, 2018 8:45 am4676 views A new lightweight, low-cost agricultural robot, developed by a team of scientists at the University of Illinois, could transform data collection and field scouting for agronomists, seed companies and farmers.

Genomic study explores evolution of gentle ‘killer bees’ in Puerto Rico Nov 16, 2017 9:30 am3715 views A genomic study of Puerto Rico’s Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees’ rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years. Scientists: Expanding Brazilian sugarcane could dent global CO2 emissions Oct 23, 2017 9:45 am3551 views Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report in the journal Nature Climate Change. Some plants grow bigger – and meaner – when clipped, study finds Oct 11, 2017 8:30 am3510 views Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these “overcompensators,” as they are called, also augment their defensive chemistry – think plant venom – when they are clipped. Virus-infected honey bees more likely to gain entrance to healthy hives Apr 27, 2020 2:00 pm3465 views Honey bees that guard hive entrances are twice as likely to allow in trespassers from other hives if the intruders are infected with the Israeli acute paralysis virus, a deadly pathogen of bees, researchers report. Their new study, reported in the Proceedings of the National Academy of Sciences, strongly suggests that IAPV infection alters honey bees’ behavior and physiology in ways that boost the virus’s ability to spread, the researchers say.
