Issue No. 16, Article 9/July 23, 2010
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.
According to the Illinois State Water Survey WARM database there was no recorded precipitation at their northern Illinois recording stations at Freeport, DeKalb, St. Charles, and Whiteside County from July 14 to 20. However, there were some spotty showers in the region during that period. The weather has been hot and humid over the past week; corn and soybeans are growing well despite the recent hot, humid, dry weather. Green clover worms and Japanese beetles are active in soybeans, but leaf feeding has been far below economic levels. Fungicide applications on corn continue in the region.
Wheat has been harvested and straw has been baled. Oats are being harvested. Alfalfa growers are reminded to monitor fields for potato leafhoppers, as high numbers have been reported in some fields.
