Regional Reports

October 4, 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

Harvest began last week and was in full activity until widespread rainfall occurred the evening of October 1. Corn silage harvest is nearly complete. Although not widespread, poor corn-stalk quality has been reported throughout the region. Producers are encouraged to inspect cornfields and target susceptible fields for harvest. Some winter wheat has been seeded.

Soybean cyst nematode screening clinics, sponsored by U of I Extension, have been scheduled for November 18 in LaSalle County and November 19 in Marshall County. Interested participants are encouraged to contact the host Extension unit office for program locations and times.

West-Central Illinois

Harvest is well under way and producers have been pleased with corn yields of early-planted corn. We have received documented reports of yields as high as 220 bushels per acre. On average, yields of early-planted corn thus far have averaged from 150 to 170 bushels per acre in many areas, with the exception of areas in the eastern part of the region where wind damage is evident. Depending on location and maturity rating, later-planted corn yields will be somewhat more variable and less impressive. Infestations of corn earworm and second-generation corn borer were prevalent in the corn crop this year. Stalk quality also appears to be less than desired in many parts of the region, most likely a result of stalk rot diseases, shallow root systems, and high corn borer numbers. Many producers have begun to shred corn stalks in harvested fields.

Soybean harvest did not begin until about the last 10 days. Yields are variable with reports of anything from 15 to 60 bushels per acre. Some producers began drilling wheat this past week.
