Scouting was done in Stephenson County. Overall the field conditions are very dry with May only bringing 1.1″ across the area so far. Temperatures have been in the upper 70s and low 80s this week with lows in the upper 40s and 50s. There are some potential rain events coming in the next week to add some moisture back into the soil. A large majority of fields have been planted and pre-emerge posts are being applied.

Corn has emerged in a majority of fields. Plants are healthy with good vigor from abundant sunshine. Growth stages are between emergence and V2 pushing V3. Despite the dry weather the residual soil moisture has produced uniform emergence.

Soybeans are beginning to emerge, by the end of the weekend most fields should emerge, but as of Wednesday only a small amount of fields had beans breaking through. Those beans were at the VE emergence or VC unifoliate unfolding growth stages. Soil top soil were dry but no crusting due to the lack of rain and the beans were having no issue breaking through the surface.

Wheat is at Feekes 10 or boot growth stage. The head is fully developed and about 2/3 the way up the leaf sheath. Head emergence is just around the corner with the warm weather. Fungicide sprays will be applied in short order as well once heads emerge. Plants looked healthy with low disease within the wheat stand.

Overall a great week for heat units and growth on the major cash crops in NW illinois and across all of northern IL. The rain potential in the next week will go a long way after a relatively dry spring and a dry winter for crop growth.

During my survey on Tuesday of this week (5/13), I made it circuit around the eastern half of McLean County. When I started my survey in the southeast corner of the county, soil moisture in fields was near normal to slightly dry on some of the hilltops. However, pop-up showers were prevalent that afternoon, and by the time I reached the northern part of the county, there was water standing in headlands, low areas in fields, and roadside ditches. So, although I’ve indicated the soil moisture conditions were “slightly wet” for this report, the truth is that is a county average with quite a bit of variability across the county at the time of my survey.

Before those pop-up showers hit, there were planters rolling in the fields. At least half of the fields I observed in my survey had emerged crop, and the majority of the remainder had been planted with maybe only 10-15% unplanted. Most emerged corn is somewhere in the V1-V2 range, and most soybeans were still at VC with the first trifoliates just starting to unfold. Weed control still looked good in most fields; earlier planted fields are starting to show some sparse weed emergence.

This week came in as a warm one! Growers are finishing planting with the favorable conditions we have had here in Knox County. For me personally, we completed nine plots total last week, two of which are research plots for Western Illinois University and Williamsfield FFA a local FFA chapters Land lab. Sprayers stayed parked for most of the week, and we started to get them ready for post emerge applications.

It has been a very busy couple of weeks as growers in Champaign County are wrapping up corn and soybean planting. I would estimate planting is approximately 95% complete for both crops. We’ve been fortunate to have a stretch of beautiful spring weather—mild temperatures, low humidity, and minimal rainfall—which has allowed for excellent planting progress. Soybeans are at the emergence to VC growth stage, with unifoliate leaves fully expanded. Corn ranges from emergence through V2, with some early-planted fields nearing the window for post-emergence herbicide applications

It’s been wet. There were a couple of breaks in the rain long enough for anhydrous and burndowns to be applied, even a little early tillage, but no planting activity as far as I’ve seen. The wheat looks decent considering the 15+ inches of rain that have fallen since April 1st. In the last week, the wheat has headed out and started to flower.

Rain the last few weeks has limited activity in many parts of LaSalle County, but this week it has dried out a bit and we’ve had perfect weather for planting. Most have completed any planned spring tillage, and since Monday (5/5/25) I have seen many planters/sprayers out in the fields. The research and demonstration plots at Illinois Valley Community College will be planted this Friday (5/9/25). I anticipate many growers will be taking advantage of the sunny, warm weather in the forecast for the next week to finish planting.

This is a good time to scout for seedling pests, particularly in fields that have been slow to emerge/develop – as we get into warmer weather over the next couple of weeks, plants can outgrow a lot of seedling insect problems. So far, I’ve only received a smattering of reports.

Early planted corn and soybean plants have emerged. Corn is in the 2-leaf stage, nearing the 3-leaf stage. Soybean plants are in the unifoliate stage with their first trifoliates developing. Surveyed 200 fields across my 3-county area, and approximately 75% of the fields are planted. Planting progress did vary widely from 30 to 100% complete due the spotty nature of this spring’s rains.
Ponding is evident in fields where the heavier May 3 rains fell. My Black Cutworm monitoring, according to the IL Natural History Survey, predicts that feeding damage may become evident around the Memorial Day weekend.

Planting is progressing in west central Illinois, though at a slower pace as most fields are already planted and only a few remain. Corn has begun to emerge, and soybean rows are becoming visible.

Everyone around here is hoping to not get any rain, so we can dry out to be able to plant again, maybe this weekend. There has been no planting or other fieldwork here since Mid-April. I attempted to take soybean populations and found a few drowned out spots that may need replanted. Some slower soybeans still trying to emerge in cool, wet conditions. Populations were running from 103,000 to 131,000.
