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.
Hot, dry weather the past several weeks has reduced expected yields for corn and soybeans, particularly corn. Numerous areas in the region had little to no rainfall during the past 5 weeks. Some growers have expressed concern about potential high nitrate levels in corn to be harvested for corn silage.
Numerous soybean fields were treated for soybean aphids in mid-August, but insecticide treatment has declined during the past few weeks. Several reports have been received of sudden death syndrome and white mold disease in soybeans. Also, gray leaf spot has been reported in corn.
Producers are encouraged to bring soil samples to soybean cyst nematode screening clinics scheduled for September 16 in Carroll County and JoDaviess County and September 26 in Stephenson County. Contact local Extension offices for times and locations.
