Issue No. 10, Article 7/May 29, 2009
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.
Uninterrupted field work was possible throughout most of the region from Tuesday, May 19, through Tuesday, May 26. Completion estimates for corn planting range from 90% to 95% in the western and central portions of the region, with lower levels in the east. Major activities the past week included corn and soybean planting, rotary-hoeing corn, and preemergence herbicide application. Corn planted around May 1 is at V2 to V3.
Corn emergence to date appears uniform and looks good. However, there are some emergence concerns, with fields that have been or need to be rotary-hoed and have not yet emerged. Precipitation through most of the region on Tuesday, May 26, will halt field activity for a few days.
Completion estimates for soybean planting range from 75% in the northwestern portion of the region to 40% to 50% complete in the central portion and lesser amounts in the east.
Wheat appears good and is beginning to head. Some alfalfa has been harvested.
Several days of dry, sunny weather late last week and early into the Memorial Day weekend allowed corn planting to resume, though field conditions were not always ideal. Storms beginning early Monday shut down much, but not all, of the region again. Rainfall amounts ranged widely; some areas received almost nothing, while parts of Madison County received 4 to 9 inches and more. Some of the newly planted corn will likely have to be replanted. The earliest wheat should soon be approaching soft-dough stage.
Depending on location in the region, producers had anywhere from 3 to 6 days of opportunity for field work. Needless to say, quite a bit of corn was planted. Other tasks included NH3 application, rotary-hoeing corn that was planted May 11 to 13, tillage work, and herbicide and fertilizer application. Quite a bit of tillage and diesel fuel have been used to bring weeds under control as well to allow fields to dry before planting and to fill in the ditches. A guess as to the amount of corn planted would be 65%. Corn maturity ranges from VE to V5.
Just a few soybean fields have been planted, and some of the early ones have emerged. Populations look good thus far.
The early-sown wheat has flowered, while later-planted is approaching flowering. Very few disease symptoms on the upper leaves have been noted. Stands are somewhat erratic, based on soil moisture levels.
Alfalfa weevil populations have not been noticeable. The alfalfa crop varies from flowering in the south to bud in the north.
