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.
The past week's major activities include applying postemergence herbicides, cultivating corn, sidedressing corn with nitrogen, and continued replanting of soybeans and some corn.
Producers have expressed concern about potential nitrogen loss and water damage to standing corn because of heavy rainfall received 2 weeks ago.
No insect damage reports have been received. However, potato leafhoppers have been observed in alfalfa regrowth.
After weeks of rain, we are now high and dry and actually wishing for a little sprinkle here and there. Wheat harvest is well under way. Yields have been reduced by barley yellow dwarf and scab. Most first-crop beans are in, with double-cropped beans to follow quickly. Corn planted is proceeding well, with sporadic reports of cutworm, southern corn leaf beetle, and grape colaspis.
Storms marched across the region again last Wednesday evening, dropping as much as 4 inches of rain in some places. Scattered areas received hail that obliterated early-planted corn. Scattered showers fell again on Saturday evening, but accumulation was minor. Temporary flooding in bottomland and flat upland areas has had a noticeable effect on soybean emergence and stand establishment, but crops in better-drained areas appear to be in good condition.
Early-planted corn has progressed well and is anywhere from the V7 to V10 growth stage, and most sidedressing of nitrogen has been completed. The first flight of European corn borer moths is winding down, and larval feeding has been noted in many fields. Soybean growth stages range anywhere from unifoliate to fourth trifoliate, with most fields in the first or second trifoliate.
Wheat is in the dough stage and has begun to turn in many areas, but fungal diseases such as scab and head smut are apparent in some fields and will likely affect yields.
The agriculture department at Western Illinois University will hold its annual Herbicide Field Plot Tour at 1:00 p.m., Thursday, June 27, at the WIU Agronomy Field Laboratory, located immediately north of the WIU Harry Mussatto Golf Course off of Tower Road north of Macomb, Illinois. The field plot tour is open free to the public, free of charge. For more information, contact Dr. Gordon Roskamp at (309)298-1569.
