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.
White mold and SDS are now beginning to appear in soybean fields.
Scattered rains occurred over the weekend and the first part of the week in varied amounts.
Leaf cupping is still being reported in soybeans, and sometimes the cupping does not occur until several days after a herbicide application has been made.
There are some reports of less-than-adequate performance of rootworm soil insecticides.
The deadline for seeding grass, legumes, or mixtures of the two for hay or pasture in northern Illinois is August 10 through 15.
An in-depth disease management workshop will be held August 17 at the Northern Illinois Agronomy Research Center near Shabbona. Deadline for registration is August 10. For program information or to register, please contact David Feltes at (309)792-2500.
Heavy rain fell in some areas of the region, with 6 to 8 inches reported in southern Macoupin County. Areas needing rain received some; and, therefore, yield prospects continue to look excellent.
Corn is rapidly advancing, with many fields now in the dent stage. Soybeans are waist high or taller, and podding well.
Some corn has been treated for GLS. Rust is also present in some fields.
SDS can be found in early planted soybeans in western Illinois.
Bean leaf beetle populations are high in some soybean fields; scouting will be necessary.
Timely alfalfa hay harvests have been a problem due to wet weather. Good- to excellent-quality hay will be somewhat scarce.
New grain-storage facilities, both commercial and on-farm, are being constructed.
University of Illinois Brownstown Field Day is August 17, starting at 3:30 p.m.
