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.
Soybean-aphid populations continue to be observed in fields but in smaller numbers than in previous surveys. In some fields that previously had high numbers of aphids, the population has crashed.
The last cutting of hay for the year is currently being made.
Corn-silage harvest is now under way.
Charcoal rot in soybeans is now evident on lighter soils, and areas with SCN are beginning to show up in fields because of the stress of a few weeks of dry weather. Yield reduction should not be extremely high in most cases.
Some corn in isolated areas has been combined.
Corn harvest has begun. Not many yield reports have been received; however, one farmer reported his yield to be "fantastic." Because of the recent warm and dry weather conditions, the corn is drying down very rapidly. Because some concern exists about deteriorating stalk quality due to several stalk rots, the harvest pace will increase very soon.
Soybean maturity is progressing quickly, and a few fields have been harvested. Some fields have been treated for bean leaf beetle. Those fields that haven't been treated may have some seed-quality problems. SCN has been found in soil samples brought to SCN clinics. Consider taking soil samples if the field doesn't yield up to expectations.
New forage seedings and last alfalfa harvest should be complete by September 10 in central Illinois.
The Hessian fly-free date for planting wheat is October 1 to 5 for most of the region.
