Alert Details

Corn earworm migration risks are predicted to remain in the low category for much of this week due to rather weak southerly winds across portions of the corn-growing region. The risk area tonight into Tuesday morning is focused in areas from South Dakota and southern Minnesota and Wisconsin southwest into the Plains and western/central corn-growing region as a warm front moves north through the upper Midwest. As the week progresses, the risk area is expected to shift southwest with time as a cool front works its way from the Great Lakes region and Canada southwest through the corn-growing region. Much of the risk from Tuesday night through early Saturday is expected to remain in the Plains and western Midwest but even there, southerly flow is expected to be rather limited and only isolated moth flights are predicted at this time.
