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 corn crop has progressed rapidly during the past week due to adequate soil moisture and higher temperatures. Soybean postemergence herbicide applications have been the main activity during the past week.
No insect outbreaks have been reported. However, potato leafhoppers are still present in alfalfa and need to be monitored. To date, very little European corn borer damage has been reported or observed.
Jim Morrison, crop systems educator, reported several soybean cyst nematodeinfested fields. Overall, soybean replants have occurred in a very small percentage of acreage, but replants have occurred throughout northern Illinois due to seedling diseases.
Although it is still dry, many locations have adequate topsoil moisture. Corn is VT-R1 and soybeans are R1-R2.
Wheat is plus 90% harvested, with double-cropped soybeans at VE.
Late-harvested wheat came in at lower test weights.
Some corn is showing "twisted whorl." Spray drift calls have become more numerous.
It is fairly quiet on the insect front. Japanese beetles are a concern at some locations. We are still waiting to assess southwestern corn borers.
Good growing conditions have existed during the past week. As a result, crop development has been rapid. Many cornfields have tasseled and soybeans are growing at a swift pace.
Very few pest problems have been reported for corn.
Roundup and other postemergence herbicide applications on soybean are being completed. Some minor disease problems, such as brown spot, have been observed in some fields.
Wheat harvest is well under way and should be completed soon. Yields are above average and quality is excellent. One flour miller indicated, "This is the best quality I have seen in 6 or 7 years." Soil conditions for double-cropping at this time are excellent.
Potato leafhopper populations are increasing in alfalfa.
Mowing of roadsides, ditches, and pastures is taking place.
