Low corn earworm migration risks are in the forecast tonight into tomorrow morning from far eastern South Dakota into central and southern Minnesota, far northern Iowa, and Wisconsin as a cold front moves its way east through the upper Midwest. South to southwest winds to the east of the front may pose an isolated migration risk to the remaining fields that are still at susceptible stages to damage. Additional Low risks are in the forecast tomorrow night into Sunday morning across southern and central lower Michigan as well as southern Ontario, Canada as the front continues to move east. Low risks are also being introduced to the forecast next Tuesday night and Wednesday as the next cold front and associated southerly winds and precipitation move back into the upper Midwest. Fields from eastern South Dakota into Minnesota may be at risk of isolated flights at that time as well. Processing and fresh market growers in the upper Midwest with crops still at susceptible stages to damage are encouraged to monitor fields and traps and take appropriate action, as needed, in the coming week.
