Alert Details

A rather persistent weather pattern is predicted to hold across much of the corn-growing region for the next week. High pressure is expected to remain in place across the Great Lakes region and eastern Midwest through much of this week while low pressure organizes in the far western Plains states. Southerly winds are expected to blow especially in the Plains and western Midwest, but should become lighter further to the east. Enough eastward expansion of stronger southerly winds at moth flight level is predicted tomorrow night into Wednesday morning especially from eastern South Dakota east into Minnesota and far western Wisconsin to warrant an isolated corn earworm moth flight risk during that time period. Otherwise, no risks are in the forecast. There are still some processing fields at susceptible stages to damage in the upper Midwest, and those growers should continue to monitor fields and take appropriate action, if needed, in the coming week.
