Alert Details

Corn earworm migration risks appear to stay rather limited over the next week as continued northwest to southeast flow remains dominant across the corn-growing region. No risk is predicted for the next three nights, but a Low risk does return to the forecast by Thursday night into Friday across Kansas and Nebraska as southerly flow returns to this portion of the region. The risk expands slightly east into western Iowa for Friday night into Saturday as low pressure slowly organizes in the Plains. With high pressure remaining in control across much of the remainder of the corn-growing region, no migration risk is being predicted through the end of the week elsewhere. Growers should continue to monitor fields at susceptible stages to damage, however, as larvae from previous flights this summer may be appearing in some spots.
