Soil Conditions: Mildly Wet (soil is wetter than normal, local vegetation is healthy)
Some growers were able to take advantage of the nice weather over the weekend and get out in the field. Most corn that was planted earlier is at VE-V1, and soybeans are at VE-VC. There is minimal standing water, but fields remain fairly wet.

Black cutworms have been observed in traps across the state for the past couple of weeks. Several counties have reported significant moth flights (9 or more moths over a 2-night span). We can use the date of the significant flight to predict potential cutting dates based on degree day predictions.
Based on trap catches in late April and May, many counties in Illinois may start observing feeding, including cutting, as early as this week (Figure 1).…

Soil Conditions: Moderately Wet (soil is damp, standing water may be present in low areas, water bodies are full)
Much like many areas of the state, northwest Illinois has received plenty of rainfall in the past couple of weeks, but there have still been enough dry days that have allowed for decent planting conditions. About 10-15% of fields in this area have visibly emerging corn,…

April temperatures were warmer than normal in Illinois, making the January-April period one of the warmest on record. April was also wetter than normal, and as rains have continued into May, questions about nitrogen (N) losses continue to increase. This concern is greater for fall-applied N, but warm soil temperatures and wet soils have some people talking about the possible need for more N to replace what might have been lost so far.…

Spring moth trapping is one month in and we thank all of the volunteer cooperators for diligently sending in trap counts each week.
The stormy weather pattern continues to bring north lots of black cutworm moths. Several counties have had significant moth flights. We expect more over the coming weeks.
While black cutworm flights have been steady these past few weeks, the same cannot be said for true armyworm. Trap catches have been low across the state.…

March was relatively warm and dry in Illinois, and corn planting started early: NASS reported that 1% of the Illinois corn crop was planted by March 31, and 2% by April 7. Those are no record-early starts, but it’s rare to have enough planted acreage to report by April 1. Most of the state has had above-normal rainfall for far in April, so we expect limited planting progress in the coming days.
In this article we’ll consider a few nitrogen-related issues to keep in mind as planting progresses in 2024:
Due perhaps to an article in the Ohio State C.O.R.N newsletter this week,…

While statewide precipitation in March averaged 3.21 inches (89% of normal), we saw a clear north-south gradient within Illinois, with totals ranging from half to an inch above normal in the northern part of Illinois to as much as up to two inches below normal in the southern end of the state. April began with above-average precipitation across the state, with 7-day totals averaging almost 2 inches,…

The Insect Trapping Network provides real-time information to growers through Illinois during the growing season.  As in past years, our spring traps focus on black cutworm and true armyworm moths. During the summer months, our focus switches to corn earworm, European corn borer and fall armyworm.
We are currently looking for cooperators to monitor both black cutworm and true armyworm traps from April 1 – May 31. By placing traps around the state, we are able to provide information on pest populations as they move into the state and predict timing of potential injury.…
