Corn earworm migration risks are present across much of the corn-growing region in the next five days. The risk level, however, is kept in the Low category at least for the time being largely due to less than optimal southerly wind speeds and the current growth stage of corn in most areas. Some silking corn, however, is present in the southwest corn-growing region so enhanced risks may be needed soon in these areas. An active weather pattern featuring low pressure across the western Plains or southern Canada and high pressure across the eastern Midwest into the eastern/southeastern United States should keep south to southwest winds blowing on a persistent basis across the corn-growing region. The risk area initially focuses on fields west of Lake Michigan and Illinois but eventually spreads east into the southern Great Lakes area and the eastern Midwest by early next week. Fresh market growers across the Midwest that planted sweet corn early should especially monitor fields in tassel for isolated moth appearances in the next week.
