For the last several years, Illinois cooperators have participated in a region-wide monitoring effort for corn rootworm beetles. (You can view the results of these efforts at https://www.rootwormipm.org; see “Adult Trapping Network” on the upper right). This effort allows us to track corn rootworm distributions over time, identify likely problem areas, and keep track of the species composition between western and norther corn rootworm. These monitoring efforts have helped us to document several trends over the last couple of years,…

Soybean cyst nematodes (SCN) cause more losses in Illinois soybeans than any other pathogen. For example, in 2021 alone, losses attributed to SCN were estimated at over 14 million bushels, valued at over $185 million. Frequently the effects of SCN go unnoticed, as many of our modern cultivars do not express noticeable aboveground symptoms of infection except under special circumstances. Even when aboveground symptoms are absent, SCN infections can result in losses of approximately 10% if the nematodes are present at sufficient densities.…

Soil Conditions: Moderately Dry (soil is dry, plants may be browning or stressed, water bodies are low)
Many areas in Northeastern Illinois are experiencing a level of drought conditions. Corn is wrapping in some fields during the day in response to temperatures and lack of moisture. Soybean growth has slowed, and most are hoping for more favorable conditions before applying post herbicides in this crop. …

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Northeastern Illinois is turning dry. Post herbicide applications are taking place in corn fields. Despite dry conditions weed growth and diversity of species has been impressive in some fields, including robust vining weeds including burcucumber and morningglory.  Early planted corn is at V6 and Soy at V2. I received reports of heavy alfalfa weevil feeding and below average tonnage from the first cutting of hay in the region. …

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Much of Northeastern Illinois has had a precipitation-free week. Soils are drying rapidly. Soy planted just before the most recent rainfall event is struggling to emerge in some fields. The soy hypocotyl cannot push through the crusted soil surface. Fields planted in this time period warrant a field scouting trip to evaluate emerged plant population.…

Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
Mostly favorable growing conditions in NE Illinois.  Spotty precipitation slowed some farmers who are trying to wrap up the 2023 planting season. Cooler soils slowed some soybean emergence, especially in high residue no-till fields. Those scouting soybean fields have reported some emerging soy exhibiting discolored cotyledons. Likely causes can include stressful emergence conditions,…
