Foliar disease can increase stalk rot incidence

Posted by Angie Peltier - Disease

Stalk rots can decrease harvestable yield - literally leaving some ears on the ground. Corn plants are top-heavy and stalk rots increase the chance that plants will fall over (lodge) due to either gravity or wind and weather events. Compounding the problem in some areas of the state, the cool, wet spring may have led to poor root development. Mid-season environmental conditions that fav...

Abundant western corn rootworm beetles: Implications for 2014?

Posted by Angie Peltier - Insects

Recent observations. I recently spent the day in the field collecting foliar disease severity data in a corn fungicide trial at the Northwestern Illinois Agricultural Research and Demonstration Center (NWIARDC).  Very little disease was present in this particular hybrid.  Common rust was the most commonly observed disease, while gray leaf spot was just starting to develop along...

Precipitation and Temperature: Implications for crop development

Posted by Angie Peltier - Weather

Precipitation April and May both saw above average precipitation, while June and July had below average precipitation ( Table ). The cool temperatures and the resulting slow crop growth that have continued into August have kept crop water demand lower than in a typical growing year. This lack of precipitation during the growing season has created soil con...

Did Western Illinois dodge the bullet for white mold in soybean this year?

Fungus survey. The University of Illinois is taking part in a fungus survey organized by Dr. Kiersten Wise at Indiana's Purdue University through funding provided by soybean check-off dollars and the North Central Soybean Research Program (NCSRP). As part of this survey, participants scout two soybean fields that had been planted to corn last year, one field that is no-till and on...

Figure. Figure. Daily high and low temperatures (between 50 and 86 degrees F) collected at the NWIARDC in 2013 were used to calculate growing degree days, a measurement of corn growth and development.

Temperatures drive corn plant development

Brian Mansfield and Marty Johnson at the Northwestern Illinois Research and Demonstration Center (NWIARDC) recently completed their last corn fungicide spray. It is a hot job: donning their personal protective equipment, mixing fungicides, and applying the fungicides with small backpack sprayers and hand-held spray booms. This task, which is part of many experiments, often takes place w...
