Regional Reports

April 19, 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

Field activity started again on a limited basis in many areas over the weekend and increased by Monday. Fieldwork has focused on anhydrous ammonia application and seedbed preparation. Black cutworm moths have been caught in traps near Freeport and also in Fulton County, but an intense moth capture has not been reported. An intense black cutworm moth capture, as defined in last week's Bulletin, is nine or more moths captured over a 1- to 2-day period.

The abnormally warm temperatures this week have contributed to pastures starting to show growth, as well as alfalfa. There have not been any confirmed reports of winter injury to alfalfa or wheat.

Southern Illinois

Field conditions are still quite wet, although warm temperatures and winds are helping to improve things. Wheat is a little behind, at 6-7 on the Feekes scale, and the alfalfa weevil is still causing damage to first-cutting alfalfa.

West-Central Illinois

Corn planting resumed last weekend in the Springfield area and other parts of the region, but there are no reports of plant emergence. Anhydrous ammonia application and primary tillage are being completed as weather and soil conditions permit.

There have not yet been any reports of insect problems in corn. However, significant moth catches have been observed in several black cutworm traps.

Giant ragweed emergence is progressing rapidly.

Leaf feeding by alfalfa weevil is becoming very evident in some fields.

Wheat fields look good, with very little evidence of disease at this time. Due to wet fields, some farmers still need to apply nitrogen and are considering aerial application.

Pay attention to wind speed and direction when applying pesticides.
