Alert Details

Corn earworm migration risks are predicted to remain in the Low category for the next five days as a couple of cold fronts move through the corn-growing region. The quick movement of these fronts along with a limited number of fields still at risk for the potential of corn earworm damage limits the risk to a Low category. Low risks are in place tonight into tomorrow morning mainly across southern South Dakota, Nebraska, and Kansas. The risk spreads north and east Saturday night into Sunday and includes fields as far north as central Minnesota and Wisconsin and as far east as southwest Michigan into Indiana. One front moves through late Sunday into Monday but yet another front is quick on its heels and returns an isolated migration risk to much of the corn-growing region by early next week. Growers with fields still at a susceptible stage to corn earworm damage, especially the fresh market and processing crops growers, should continue monitoring their crops and take appropriate action if it is needed.
