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

Soil moisture remains good, and crop conditions are, in general, excellent.

Corn is starting to dent. Scattered fields and patches are showing nitrogen deficiencies due to flooding or other nitrogen problems, mostly related to source and timing. There have been some scattered reports of earworm damage and mold.

Soybeans are setting pods. Sudden death syndrome is starting to show up.

Southern Illinois

The earliest-planted corn is rapidly approaching black layer. The crops in some areas in the south and southeastern parts of the region are beginning to show the effects of the hot and dry conditions that have settled in for the past week. For the most part, however, soil moistures have thus far been adequate to allow the crop to continue development without obvious leaf rolling. The most obvious problems being seen on corn are foliar diseases such as gray leaf spot and northern corn leaf blight, firing of the lower canopy due to nitrogen deficiency, and nosing back of the tip kernels due to environmental stresses.

The soybean crop continues to be quite variable. Late-planted fields are at or approaching R3 and showing the greatest negative effects from the hot, dry conditions. Early-planted fields are at R4-R5. So far, sudden death syndrome has not been a widespread problem in the southern region, although it can readily be found just to the north along IL Route 16 in Jersey County.

Livestock producers wanting to stockpile tall fescue for deferred grazing should be applying nitrogen fertilizer to those pastures now.
