Alert Details

A cold front is expected to continue southeast through much of the corn-growing region over the next 24 hours. In its wake, northwest flow is likely to be dominant so little to no corn earworm migration risk is predicted through mid-week. By late week, however, southerly winds ahead of the next developing weather system in the Rocky Mountains leads to Low migration risks mainly west of I-35 by Thursday night into Friday and then generally west of the Mississippi River Friday night into Saturday. Despite the lack of risk early in the week, growers are strongly encouraged to check traps and scout fields over the next several days as some new moths likely flew into portions of the corn-growing region late last week and into this past weekend given the favorable weather pattern and more advanced crop stage in mid-south and southern states host/source regions. These moths may begin appearing in traps this week.
