Issue No. 11, Article 8/June 4, 2004
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.
Widespread precipitation occurred throughout the region on May 30 and 31, with numerous areas reporting 2 to 3 inches or more of rainfall. Hail damage was reported in Will County. The latest rainfall coupled with earlier precipitation over the past several weeks has contributed to numerous field ponding and flooding near creeks and rivers. Some replanting will occur. If emerged corn was flooded and replanting to soybean is considered, producers are reminded to review the recropping restrictions on previously applied herbicides.
Soil conditions the past 3 weeks have hindered soybean planting, with the majority of planting last week occurring on May 28 and 29. Several reports have been received concerning acetamide herbicide, applied preemergence, causing injury in corn. The cool, wet growing conditions have contributed to current herbicide plant injury. However, warmer temperatures will alleviate the conditions.
Numerous reports have been received of bean leaf beetle feeding in soybeans, but reported populations and damage have been below economic thresholds. The weather has been very challenging for alfalfa growers to produce high-quality forage and has delayed crop postemergence herbicide applications and sidedressing of nitrogen.
