Regional Reports

May 24, 2002
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.

Northern Illinois

Corn planting is about 95% complete in northwestern Illinois and more than 80% complete in northeastern Illinois. There are some small areas in northeastern Illinois that received heavier rainfall on May 11 that are considerably farther behind. Heavy frost was experienced on the mornings of May 18, 19, and 21, causing corn leaf injury, but it will have minimal yield effect since most of the corn is from the 1- to 3-leaf stage. Weather conditions have limited corn growth and caused the crop to have a yellow, unhealthy color.

Soybean planting in some areas will easily surpass 50% before the next rainfall, which is expected on Thursday, May 23. Fieldwork and planting started again in far northwesten Illinois on May 18, with other areas in the region starting up again on May 21. To date, there have been no reports of frost injury on the limited acres of emerged soybeans.

Alfalfa harvest has started this week.

West-Central Illinois

A limited amount of fieldwork has begun in the region. These operations include anhydrous application, tillage, and postemergence herbicide applications on corn. Planting will resume very soon, also, if no additional rain falls.

Cool, wet weather has prevented the corn from growing very much in the last week. Most of the corn is still in the V2 to V3 stage. But this may change rapidly as growing conditions improve.

Not many pests have been reported in corn. However, as soil conditions get better, more thorough scouting will begin. Cutworm will be a major concern because of the excessive weed growth in some fields that will still be planted to corn.

Alfalfa harvest has begun, also. If the field was not treated for weevil, quality will be down significantly. Pasture growth also has been suppressed because of the cool, wet weather.

Wheat is headed, and the wait begins to see if disease will set in as a result of the wet weather.
