Issue No. 19, Article 4/August 4, 2006
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.
The corn and soybean crops look very good throughout the region. Soybean aphids are present in many soybean fields, but populations are well below economic thresholds. Recent high temperatures have hindered soybean aphid populations. Several Extension educators have reported grasshoppers feeding in soybeans. Greg Clark, crop systems educator, Whiteside County, reported observing soybean sudden death syndrome there.
Wheat harvest is complete, with most yields reported in the range of 80 to 100 bushels per acre. Oat harvest is occurring this week.
