Regional Reports

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:

We hope these reports will provide additional benefits for staying current as the season progresses.

East-Central Illinois

Limited corn harvest has started. The lowest moisture report has been 19%, but around 24% is more common. Yield surveys suggest that variations between and within fields will be high and that the USDA report may have been optimistic. Ears with small amounts of Diplodia and other ear rots are relatively easy to find.

Soybeans are taking advantage of the cooler nights to improve seed and pod fill. Early-maturity varieties are starting to turn. Sudden death syndrome is present in some areas but mostly at low levels.

Northern Illinois

According to the Illinois State Water Survey WARM database, 2,416 growing degree-days have accumulated from April 20 to August 23 at Freeport and 2,318 at DeKalb. Accumulated GDD are above the 11-year average by 275 at Freeport and 173 at DeKalb. The corn crop is progressing very well, with about 70% in the dent stage, and soil moisture is adequate in most of the region.

Soybeans have podded well, and yield expectations are high. Soybean sudden death syndrome is becoming more common throughout the region but at present is generally limited to small areas within fields. Soybean aphids are present, but reports indicate low numbers.
