Alert Details

A cold front will make its way somewhat slowly to the southeast across the central and eastern corn-growing region over the next several days. Ahead of the front, south to southwest winds will be common but not overly strong and should actually weaken as we head into the weekend. Nonetheless, these winds may pose an isolated black cutworm migration risk and Low migration risks are predicted tonight into tomorrow mainly east of the I-35 corridor from eastern Kansas into Iowa and southeast Minnesota as far east as southern Ontario, Canada and central Ohio/Kentucky. Low risks then focus mainly east of the Mississippi River and from southern lower Michigan and northern/central Illinois and points southward from tomorrow night right into Sunday before the front finally clears much of the corn-growing region. Growers are encouraged to monitor traps for new flights but also calculate degree days from observed flights in April and early May as some new generations may be appearing in some areas now or very soon.
