Issue No. 21, Article 4/September 10, 2010
Extension center educators, unit educators, and unit assistants in northern, west-central, east-central, and southern Illinois prepare regional reports to provide more localized insight into pest situations and crop conditions in Illinois. The reports will keep you up to date on situations in field and forage crops as they develop throughout the season. The regions have been defined broadly to include the agricultural statistics districts as designated by the Illinois Agricultural Statistics Service, with slight modifications:
- North (Northwest and Northeast districts, plus Stark and Marshall counties)
- West-central (West and West Southwest districts, and Peoria, Woodford, Tazewell, Mason, Menard, and Logan counties from the Central district)
- East-central (East and East Southeast districts [except Marion, Clay, Richland, and Lawrence counties], McLean, DeWitt, and Macon counties from the Central district)
- South (Southwest and Southeast districts, and Marion, Clay, Richland, and Lawrence counties from the East Southeast district)
We hope these reports will provide additional benefits for staying current as the season progresses.
A big rain last week brought harvest to a temporary halt, but most combines were rolling again after only short delays. Corn harvest is progressing rapidly. Yields are quite variable. Some are very good--the Shelby County Extension plot averaged 221 bu/A. Not wanting a repeat of last year, many farmers are taking advantage of the good weather to do some fall tillage as soon as fields are harvested.
Some of the later soybeans may have benefited from the late rain, but most fields are now starting to turn.
The crop has matured a great deal over the last few weeks, but "full harvest" is still several weeks away. There has been some limited corn harvest during the past week, mainly in the southern third of the northern region. Harvest has focused on the shorter-season hybrids (around 103-day corn), with moisture reports in the low 20s. Many of the full-season hybrids have not quite reached black layer, especially in the northern half of the region. The windy days early in the week caused some corn to start to go down in some stressed areas.
Many soybean fields are turning and shedding leaves, but producers will be harvesting corn acres before many soybeans are ready for harvest.
