Crops

URBANA, Ill. – In the battle against herbicide-resistant weeds, farmers are increasingly eager to add non-chemical control methods to their management toolbox. Impact mills, which destroy weed seeds picked up by a combine, have been shown to kill 70-99% of weed seeds in soybeans, wheat, and other small-statured cropping systems.

URBANA, Ill. – The U.S. and China recently agreed to a phase one trade deal that aims to resolve the current trade war between the two countries. But that is just the latest development in longstanding and complicated U.S.-Chinese trade disputes.

The U.S. Department of Energy has awarded a $3.3 million grant to a multidisciplinary research team at the University of Illinois at Urbana-Champaign to develop a precise system for measuring greenhouse gas emissions from commercial bioenergy crops grown in central Illinois.

URBANA, Ill. – Researchers from the University of Illinois College of Agricultural, Consumer and Environmental Sciences and the Illinois Natural History Survey have published their 2019 field research results related to crop pests and diseases in Illinois.

URBANA, Ill. – For corn growers, the decision of when and how much nitrogen fertilizer to apply is a perennial challenge. Scientists at the University of Illinois have shown that nanosatellites known as CubeSats can detect nitrogen stress early in the season, potentially giving farmers a chance to plan in-season nitrogen fertilizer applications and alleviate nutrient stress for crops.

URBANA, Ill. – Like most plants, soybeans pair up with soil fungi in a symbiotic mycorrhizal relationship. In exchange for a bit of sugar, the fungus acts as an extension of the root system to pull in more phosphorus, nitrogen, micronutrients, and water than the plant could on its own.  

URBANA, Ill. – When a plant senses an invading pathogen, it activates a molecular signaling cascade to switch on its defense mechanisms. One such mechanism involves sacrificing host cells to the pathogen. This is a tightly controlled process that involves the work of plant proteins to ensure that the sacrificial cells are only killed if the pathogen is attacking. This process, called the cell death response, ensures that only a few host cells die.

URBANA, Ill. – Fall-applied anhydrous ammonia may not fulfill as much of corn’s nitrogen needs as previously assumed. According to a new study from the University of Illinois, the effectiveness of the practice depends on the soil.

The study used a “tagged” form of ammonia to determine how much of the nitrogen in corn grain and plant material comes from fertilizer, versus nitrogen supplied naturally by the soil.

URBANA, Ill. – The United States is the world’s leading producer of soybean and the second-leading exporter. Nearly 90% of oilseed production in the U.S. comes from soybean. A biological threat to soybean crops in America could affect the global economy, and the result could be devastating to the American soybean farmer, according to researchers in the USAID Soybean Innovation Laboratory (SIL), housed in the College of Agricultural, Consumer and Environmental Sciences at the University of Illinois.

URBANA, Ill. – The Soybean Innovation Lab (SIL) recently launched Africa’s first free, open-access, certificate-based online course in integrated pest management (IPM) and pesticide safety.

Insect pests, weeds, and diseases are common problems for farmers worldwide. In sub-Saharan Africa, pest control is typically manual, which is labor-intensive and often ineffective.
