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:

  • 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.

Northern Illinois

Not a great deal has changed from last week, as the corn and soybean crops certainly look good throughout the region. Additional reports have been received of soybean sudden death syndrome in some areas. Dave Feltes, Extension IPM educator, reported observing second-generation European corn borer egg masses in JoDaviess County. Soybean aphids and Japanese beetles are common throughout the region in soybeans, but no economic damage has been reported for about a month.

Greg Clark, Extension crop systems educator, reports observing white mold and downy mildew disease in soybeans in Whiteside County. White mold disease has also been reported in some northern LaSalle County soybean fields.

West Central Illinois

Moisture has been very spotty in the region, with the western side being the driest. Last week's high temperatures and wind brought an end to some cornfields in the western side of the region. Many fields have various degrees of corn dying, with one report of a field being completely brown. Many stalks are brown from the husk to the ground, with the husk hanging down and the shank dead. An ear of corn tested for moisture on Friday by one producer tested at 35%, when the entire plant had been green the week before. All ears have some degree of kernel abortion, with some aborting over a third of the kernels. The eastern side of the region is faring a little better, with most corn just starting to brown on the lower stalks. Most fields are at or very near dent stage.

Corn silage harvest has begun on the western side, with moistures of 65% being reported.

Hay and pasture growth has ceased, and quite a few producers are feeding hay on the western side. The opposite is true to the east. Many pastures have greened back up, and hay feeding is declining.

Soybeans are still holding on. There is wilting in some areas of the fields in the afternoon. Minor insect activity of soybean aphids can be found in most fields.
