Alert Details

As heat unit accumulations continue to increase, western bean cutworm emergence will increase and expand especially across the western and southwestern portion of the corn-growing region. Moderate developmental risks are in place for the next five days from northern Kansas into western Missouri and will eventually reach into southern Nebraska and southwest Iowa as 25% and greater emergence thresholds are met in these areas. Low developmental risks are in place as far north as central Nebraska, western and southern Iowa, northern Missouri, and into western Illinois by the extended forecast period early next week.
