Black Cutworm
Black cutworm migration risks will be on the increase as we head into the weekend and early next week as low pressure develops over the Plains, leading to an increase in south to southwest winds across a good portion of the corn-growing region. No risk is predicted tonight into tomorrow morning, but Low risks enter for the forecast tomorrow night into Saturday morning mainly west of I-35 and north of I-70, or from the Plains states into western Minnesota and Iowa. This same region is also under a Low risk Saturday night into Sunday morning, but then the risk shifts east and as wind speeds increase, especially from the central Plains into the upper Midwest, Moderate risks are predicted from northeast Nebraska and northwest Iowa north into eastern South Dakota and central/southern Minnesota where some scattered moth flights will be possible ahead of a cold front. Low risks remain along/east of the southeastward-moving cold front early next week, with fields as far east as I-75 in lower Michigan and Ohio potentially being affected. Greatest black cutworm concerns are in recently planted, or not planted, fields at this point from these new potential flights.
