Alert Details

Low corn earworm migration risks are predicted for late week and into next weekend as a low pressure system develops in the High Plains and moves east through the corn-growing region. Southerly wind flow to the east of a trailing cold front may allow for some isolated corn earworm moth flights into especially Kansas, southern Nebraska, and western Missouri Thursday night into Friday, and then from Missouri into portions of Illinois, Kentucky, Indiana, Ohio, and southern lower Michigan Friday night into Saturday as the cold front moves east. This threat is primarily focused at early maturing fresh market and produce growers as these early-season flights can cause localized damage given the lack of other nearby hosts not being at a susceptible stage to damage yet, so corn earworms find those fields that are and can result in localized feeding even at this point in the growing season.
