Regional Reports

September 7, 2001
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

Some reports of lodged corn were received, but lodging does not appear to be as severe and widespread as last year. However, growers are encouraged to inspect all fields and identify any areas that may need to be harvested early. Corn silage harvest is now under way. In some areas near the Wisconsin state line, growers are concerned about potential nitrate levels in corn silage. Limited corn harvest is expected to begin this week in some sandy soils in parts of Grundy County.

Several weeks ago, soybean sudden death syndrome had become more evident throughout the region but will not have the same impact on yield as experienced across northern Illinois in 2000.

For alfalfa growers in the northern quarter of the state, a reminder that September 1 was the recommended date for final alfalfa hay harvest during the growing season.

Soybean cyst nematode screening clinics, sponsored by Extension, have been scheduled for September 13--JoDaviess County, September 21--Lee County, and September 21--Whiteside County. Interested participants are encouraged to call the host Extension office for program location and time.

Southern Illinois

The growing season and summer field days are winding down. Most areas have received rain showers, and in general soil moisture is good. Air temperature has been close to perfect for crop maturity and drydown.

Some corn harvest has been completed in early-planted areas. However, many farmers are patiently waiting for mid-20s moisture corn to dry a few more points. Soybeans (except double crops) are mostly R6­R7, with early varieties beginning to mature.

Maturing corn has exhibited gray leaf spot, anthracnose, and pith weevil damage, resulting in ragged appearance. Soybeans have struggled through early SDS symptoms and a little frogeye and now look more promising with improved soil moisture.

Late-season weed surveys remind us how competitive waterhemp, giant ragweed, lambsquarter, and pokeweed can prove to be.

Have a safe harvest season.
