Alert Details

An active weather pattern is expected to return to at least the central and southern corn-growing region late this weekend and early-mid next week. A frontal boundary is expected to slowly shift southeast next week, and to the south and east of the front we may see some isolated corn earworm moth migration events. Low risks are in place as early as Sunday night into Monday morning mainly south of I-90 and west of I-55, or from the central Plains north into southern South Dakota, extreme southern Minnesota, southern Wisconsin, and into Illinois. The risk expands slightly east on Monday night into Indiana and southwest lower Michigan, and then focuses mainly over the southern Great Lakes region and eastern corn-growing region by mid-week. Growers should continue to monitor traps and scout fields, especially if the crop is still at a susceptible stage to damage (primarily fresh market and sweet corn growers/processors at this point).
