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.
Wind-damaged cornfields have slowed the corn harvest in several northern Illinois counties. Anthracnose is the leading disease problem in many of the damaged fields.
Early yield reports on corn are a mixed bag; some individuals are very happy with their yields, while others have been somewhat disappointed.
Early bean yield reports indicate yields have not been what individuals were expecting, but this is based on only a small percentage of the acres harvested at the time of the reports.
Rain on October 3 has halted the bean harvest for a while, and the first killing frost of the season is predicted for October 6 or 7, officially ending the growing season in northern Illinois. All crops are mature except for some beans that were planted very late in drowned-out spots in fields.
Harvest is progressing rapidly with about 60 to 70% completion in some areas. Some farmers are finished. Wet soil is a major problem in small parts of the region, which is making harvest difficult.
In general, corn yields have been very good, but soybean yields have been disappointing. Field averages for corn are 170 to 190 bushels per acre, with some plot yields as high as 250 bushels per acre. Soybean yields ranged from 28 to 63 bushels per acre, with most yields at 45 to 55 bushels per acre.
Major yield-limiting factors for corn include stalk rot and European corn borer, which caused severe lodging in some fields. SDS, root rots, and excessive moisture have limited soybean yields.
Overall, the crop will be a little smaller than anticipated, and few storage problems have been reported.
Postharvest tillage has begun, and farmers are waiting for lower soil temperatures to begin nitrogen applications.
Some unusual weed problems may be addressed with a fall application of a herbicide.
