Alert Details

Low corn earworm migration risks are in the forecast for the next three nights as a rather persistent fetch of south to southwest winds in association with a building heat dome spreads across especially the southern two-thirds of the corn-growing region. A cold front late in the weekend should bring an end to any migration threats, but until that occurs, Low risks are in the forecast on a nightly basis across Kansas, Missouri, and Kentucky as far north as near the I-90 corridor in southeast South Dakota, southern Minnesota, Wisconsin, and eventually into lower Michigan and adjacent areas of the southern Great Lakes region. Growers with corn that has fresh silks and also vegetable and fresh market growers are encouraged to monitor fields and check traps over the next week as it is quite probable that at least some new moths will appear. Source regions across the southern states and mid-south region are still attractive to corn earworm given their growth stage right now, so we do not foresee large scale flights at this time, but still something to keep an eye on.
