Alert Details

Black cutworm migration risks are in the forecast over the weekend and into next week as a fairly potent low pressure system and cold front move through the corn-growing region. Southerly winds will already be on the increase by tomorrow, and Low migration risks are in the forecast mainly south of I-90 from Kansas and eastern Nebraska all the way to western Ohio tomorrow night into Sunday. Low risks continue Sunday night into Monday mainly east of I-35 from eastern Kansas into Missouri and Iowa and points east as the cold front begins to move southeast. Monday night into Tuesday, the Low risk focuses mainly from southeast Missouri and Illinois east into the southern Great Lakes and eastern corn-growing region. South to southwest winds ahead of the front may be gusty at times, but in comparison to previous documented moth flights the overall setup is not quite at the level that an upgrade to a Moderate risk is warranted at this time. Still, growers should continue to monitor traps and also calculate heat unit accumulations from previously recorded flights especially with an increasing percentage of corn being planted and emerging in the coming weeks.
