Call for Grain Samples, 2015

  • September 4, 2015

  • Emerson Nafziger

With funding from the Nutrient Research & Education Council (NREC) we started a project in 2014 to try to get a better idea for how much nitrogen (N), phosphorus (P), and potassium (K) are contained in harvested grain of corn, soybean, and wheat.
In 2014 we tried to get yield level for each sampled field in order to see if yield level affects nutrient content. We found that it did not, and so we dropped the requirement to include yield level (will leave it as an option) and ask only for the county in which the sampled field was located.…

Western Corn Rootworm Densities Far Below Average in Illinois Corn and Soybean Fields

  • September 2, 2015

  • Michael Gray

As part of a USDA National Institute for Food and Agriculture (NIFA) sponsored grant, surveys of insect pests were conducted in randomly selected corn and soybean fields across 28 counties throughout Illinois this summer. Fields were sampled during two discrete periods: July 27 – July 31 and August 12 – August 24. Within each county, five cornfields and five soybean fields were sampled. Within a cornfield (away from the field edge and end rows), 20 consecutive plants were examined carefully for northern and western corn rootworm adults.…

The End of an Era

  • August 12, 2015

  • Aaron Hager

In early 1998, Extension specialists in the Department of Crop Sciences (Drs. Kevin Steffey, Mike Gray, Bob Hoeft, and Emerson Nafziger) launched a new educational program dubbed the Corn & Soybean Classic. The program consisted of a series of regional meetings at which extension specialists shared with those in attendance the most current and relevant information related to crop production, pest management, and farm economics. Annually for 18 years, 7 to 10 specialists spent many long hours compiling the information generated from applied and basic research programs into a format that was shared with an audience that ranged in size from 800 to over 1300.…

Got Crazy Top?

  • July 30, 2015

  • Emerson Nafziger

Crazy top, named for the odd formations of the leaves or tassel due to hormonal effects of the disease, is typically found on corn plants that were submerged for a few days early in the growing season. A description of the disease and of its symptoms can be found at http://bulletin.ipm.illinois.edu/pastpest/articles/200220c.html
While a lot of corn was submerged during early growth in Illinois this year, we haven’t been seeing a lot of this disease.…

Symptoms of Sudden Death Syndrome Begin to Appear in Soybeans

  • July 28, 2015

  • Aaron Hager

Last week, symptoms of sudden death syndrome (SDS) began to appear in April 15-planted soybeans at the University of Illinois’ Northwestern Research Center in Warren County. Weather during the 2015 growing season has been favorable for the development of SDS: cool, moist soils after planting and frequent rains ever since. Symptoms began appearing approximately 3 weeks earlier than in 2014.
While the fungus that causes SDS (Fusarium virguliforme) infects roots of soybean seedlings very early in the growing season,…

Does Corn Still Need Rescuing?

  • July 21, 2015

  • Emerson Nafziger

The 2015 Illinois corn crop continues to develop on schedule, with 75% of the crop having reached silking by July 19. But the crop condition rating continues its steady downward trend, with the good + excellent percentage now at 55%, down from its high of 79% at the end of May. Virtually all of this decline is due to standing water, past or present.
Rainfall frequency and amount has moderated some, but parts of western Illinois have received more than 6 inches so far in July.…
