With northwest flow dominant across much of the corn-growing region, any corn earworm migration risks are very limited to none until we reach the weekend. By late Friday into Saturday, southerly winds should begin return to the Plains states ahead of a developing low pressure system to the east of the Rocky Mountains. Low risks are predicted from I-90 southward from southern South Dakota into Kansas. The Low risk then spreads east with each successive night, and eventually reaches into Wisconsin and Illinois by early next week. Despite the lack of risks for the next few days, growers all across the corn-growing region should be monitoring traps and scouting fields as some corn earworm moth flights did occur late last week and into this past weekend.
