Black cutworm migration risks continue in the forecast for the next three nights until a cold front passes much or all of the corn-growing region by late this week. Low risks are predicted tonight into tomorrow mainly along and east of the I-35 corridor from western Missouri through central Iowa and southeast Minnesota east as far as lower Michigan and western Ohio. Low risks shift only slightly east tomorrow night into Thursday morning, and then focus mainly east of the I-55 corridor from southeast Missouri and central Illinois and points east as the cold front begins to accelerate more quickly to the east. Growers with newly emerged corn should be scouting fields as any flights late last month and early this month may be producing larvae that could be affecting fields. Flights at this point will be of more concern to re-plant or late planted corn in mid-June.
