The corn-growing region weather pattern is finally showing signs of progression, with a cold front now entering the High Plains region and high pressure advancing east into the eastern United States by this weekend. Low corn earworm migration risks will continue to the east of the cold front, with the risk area tonight into tomorrow mainly east of a line from south central Kansas to Minneapolis, Minnesota and as far east as the I-69 corridor in southern lower Michigan and Indiana as well as western Kentucky. Low risks shift further east tomorrow night into Sunday, mainly east of I-35, and then late in the weekend and early next week, the best chance for mainly isolated corn earworm moth flights looks to focus slightly further east of I-35, especially along/east of the Mississippi River into the southern Great Lakes and eastern corn-growing region. The front does look to be a little more progressive than predicted the past few days, so most areas will be out of any migration risk by later next Tuesday. Processors and fresh market growers are encouraged to continue scouting and trapping efforts until harvest as some moth flights have been confirmed in the past week or so despite the calendar saying mid-late September.
