Ratings for the 2024 Illinois soybean crop have been high most of the season, and the August 1 estimate released by NASS is for yield at average 66 bushels per acre. That would be a new record for Illinois, 2 bushels higher than the 2021 yield, and 4.9 bushels higher than the 2024 trendline yield.
While the soybean yield prospects are good, this has been an unusual year, and this lets us watch how the crop’s response to the weather is playing out in the field.…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Soybeans are at R6-R7 throughout the area, and corn is at R4-R5. We have not had any significant rainfall events for a couple of weeks, leading to dryer conditions. I still have not heard any reports of or seen increased incidence of disease or insect issues. Some silage chopping has begun.…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
Recent precipitation and current cool conditions are favorable for both corn and soy crop grain fill. The extended forecast is dry and warmer, which could expedite the grain fill window. For crops on some lighter soils in the Northeast, recent rains appear to have arrived late. Corn in sandy and soils with poor water holding capacity senesced quickly over the recent week.…

Wet weather delayed planting of some of the 2024 Illinois corn crop, but stands (except in drowned-out low spots) are generally good. Warm, dry weather in June caused some water stress in places, but kept development moving and helped roots to establish. July-August rainfall totals have been above normal for almost the entire state, while temperatures have been normal to a little below normal.
Reflecting the favorable weather this growing season, the August 1 estimate of yields,…

Soil Conditions: Moderately Dry (soil is dry, plants may be browning or stressed, water bodies are low)
Rain is in the forecast which would greatly benefit the soy crop in drier areas of Northeast Illinois, that crop is still at R5 or beginning seed. As we reach mid R5 we can expect the remobilization of nutrients from leaves and stems to start. While few reports of soy disease have been noted to date,…

Stalk rot in corn primarily leads to stalk breakage and lodging, and consequently yield loss. Stalk rot is caused by pathogens (fungi or bacteria). While abiotic stress like flooding, droughts, or insect infestations can cause similar damage, the symptoms in the stalk can vary depending on the cause.
Stalk rot pathogens attack the pith, degrading it and destroying the vascular tissue within the stalk. This disruption affects water and nutrient movement within the plant, resulting in premature plant collapse.…

Soil Conditions: Mildly Dry (soil is drier than normal, plant growth may have slowed)
This week precipitation has been mixed in northeast Illinois, areas north of the Rte. 80 corridor have received multiple rainfall events while areas south have received limited to no precipitation. Soy continues to progress, reaching R5, beginning seed stage. Depending upon variety maturity and planting date, most corn fields visited were R3-R4 to R4-R5.…

LaSalle County
Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
We have gotten quite a bit of rain in the last week in LaSalle County, with most areas seeing between 2-3 inches.  Some areas in Bureau County received up to 4 inches of precipitation in the past week. With this, many fields have fairly saturated soils, but I have not noticed any ponding. …

Stephenson County
Soil Conditions: Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
After last week’s storms, the corn that was most heavily impacted (which was minimal) has mostly come back up. Everything still looks very healthy as we continue to receive rainfall. Corn is silking and soybeans are anywhere between R3 and R5. I have seen some rootworm beetles and subsequent silk clipping but not in high amounts.…
