Alert Details

The weather pattern across the corn-growing region is expected to change by late week and into next weekend, and may bring the next corn earworm migration risk back into the picture. Given the time of year and crop stage both in the source region (mid-south United States) and in the actual corn-growing region, the potential is there to see some more substantial moth flights by the end of the week and into next weekend. Given forecast uncertainty in where large storm complexes will likely track, however, we are keeping the overall risk in the Low category mainly west of Lake Michigan, or from the Plains states east into Wisconsin and Illinois. Growers with crops at susceptible stages to damage, especially along and north of I-80, should prepare for potential moth flights within the next week. Forecast risk levels are likely to increase in subsequent forecasts this week.
