Regional Reports

May 4, 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.

East-Central Illinois

Many farmers have finished corn planting and are well into soybean planting. Rainfall amounts have been low, and planting has been an almost continuous activity. Warm soil conditions have contributed to rapid emergence and good development.

Northern Illinois

Planting has been going full speed during the past week, with planted corn acres reaching more than 50% across northern Illinois. Some soybeans have been planted as well. While the weather has cooperated for corn and soybean planting, continual windy conditions have slowed herbicide applications and contributed to some drift complaints.

Dale Baird, crop systems Extension educator, reported an "intense" capture of black cutworm moths on April 30 and May 1.

Southern Illinois

Rapid planting progress has continued, with many farmers completing corn. 2001 will probably set the record for the amount of early-planted corn in southern Illinois. Some farmers are planting soybeans, while others have stopped due to dry soils.

Parts of southern Illinois are now listed as "moderate drought" areas on the U. S. Drought Monitor. There were some spotty showers on April 30, but most areas have become quite dry. March and April, pending final reports, had less than 50% of normal precipitation.

There have been reports of black cutworm damage to corn. Prairie vole populations appear to be at fairly high levels.

Wheat is now late boot to early heading in south-central Illinois.

West-Central Illinois

Dry conditions continue in parts of the region. A few farmers are waiting to plant soybeans until soil moisture improves.

Southern corn leaf beetle has been identified in several fields. Some fields have sufficient damage to justify an insecticide application.

Alfalfa weevil activity is increasing, and early cutting is occurring in some areas.

There are a few reports of corn-emergence problems due to soil compaction or herbicide injury.

Bean leaf beetles have emerged and can be found in alfalfa fields. Early-planted soybeans should be scouted for damage.
