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.
Warmer temperatures and sunshine are causing the lime-green patches in soybean fields to become a more normal dark green. Rainfall has delayed some postemergence herbicide applications, and grasses are heavy in many fields. Early evidence of SDS and rhizoctonia/fusarium has been diagnosed.
Southern counties have reported large numbers of moths that have tentatively been identified as armyworm moths. All the yellow flowered weeds seem to be blooming at once; wild parsnip and yellow sweetclover are two of the most common.
The high temperatures of the last few days seem to have caused the wheat to turn almost overnight. Many farmers have taken advantage of the weather to get their hay cut and put up.
Crop growth and development have accelerated with the warmer temperatures. Soybean planting continues in some areas due to the wet field conditions this last month. Reports of damping off in soybeans have increased this week, and some fields have been replanted. Additionally, other soybean fields are having difficulty emerging due to soil crusting.
First cutting of hay has yet to be completed. Numerous fields have been cut, received rain, and have yet to be baled.
Reports of armyworm infestations have slowed this week.
Summertime temperatures have arrived in southern Illinois. Topsoil moisture now permits planting and other fieldwork to resume. The U.S. Drought Monitor continues to show most of southeastern Illinois as abnormally dry.
Limited wheat harvest has begun. There is some concern about the availability of barges, with the Mississippi at flood stage. Early corn is rapidly growing. Later fields may have corn at multiple stages of growth. Many soybean fields are receiving postemergent herbicide spray applications.
True armyworm flight continues but may have peaked in the southernmost counties. Southwestern corn borer flight continues to be quite high in the deep south and increasing in Franklin County.
Warm and dry weather has returned to the region. Soybean planting will be completed, and as some fields dry, farmers will evaluate soybean stands and decide whether replanting or patching is necessary. As a result of the recent wet weather, seedling diseases will probably be noticeable in some soybean fields.
The drier weather will also allow farmers to finish sidedressing corn. Yellow corn has appeared in the wet, poorly drained areas of some fields.
Postemergent herbicides are needed in many cornfields and soybean fields. Some cultivation will be done also.
Wheat is turning rapidly, with an early harvest anticipated. Symptoms of wheat scab were observed in one field.
First-harvest alfalfa is complete, while some producers will be taking second cuttings very soon.
