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.
Most of the area received about 1/2 inch of rain, with some areas receiving up to 1 inch. However, progress was made in finishing up corn planting, except for "drowned-out" areas, and progress was made with soybean planting. Other activities focused on rotary hoeing and early corn postherbicide application. Corn emergence last week was very slow, with some reports of corn leafing out under ground. Warmer temperatures beginning on May 26 have contributed to corn exhibiting a more normal green color. Frost 10 days ago will have minimal yield effect on corn.
Alfalfa harvest is under way, and some fields have alfalfa weevil populations approaching economic thresholds. Reports of fungicide application on wheat were received.
Isolated heavy rain fell in some parts of the region, once again filling the ponded areas and delaying planting.
A significant amount of corn was planted and replanted during the past week. Planting is about 90% complete. Early-planted corn is still not growing very rapidly, with most of it still in the V2-V4 stages.
Not many insect problems have been reported in corn. However, wireworm has been observed in some fields in the western part of the region. Postemergence herbicides are being applied where soil and weather conditions allow them.
Soybean planting has begun, with about 15% to 20% of the acres planted. No pest problems have been reported in soybean. Frost damage on soybean is suspected in some fields in western Illinois.
Hay harvest has begun in the area. Quality has been reduced because of the extreme wet weather.
